行波堆 Traveling Wave Reactor

通过对抑制堆芯燃料的分布和运行,核燃料可以从一端负级启动点燃,裂变产生的多余中子将周围不能裂变的U-238转化成Pu-239,当达到一定浓度之后,形成持续的裂变反应,同时开始焚烧在原位生成的燃料,形成行波。

行波以增殖波先行焚烧后增殖,一次性装料可以连续运行数十年甚至上百年
形象的说,行波堆像蜡烛,用火柴点燃后逐渐烧尽,并可以点燃其他蜡烛。

顏料

发泡油墨 . 丙烯颜料 4 Types of Acrylic Paint ♦油漆

丙烯颜料

丙烯颜料又称为塑胶彩或压克力颜料, 英语为“acrylic”,发明于1950年代,是颜料粉调和制成的。 丙烯颜料可以用水或稀释剂稀释,但在干后迅速失去可溶性,不再溶于水。 且不易褪色,持久性较好。 另外,丙烯颜料也是大多数人学习油画前的替代品,因为两者的成品及技法有不少类似之处。 丙烯颜料绘画技法又可分为类似水彩画的透明技法以及类似油画的不透明技法两种运用。 在压克力颜料中加入清水,则可让颜料呈现透明似水彩的状态。 若只调和微量的水分或者不加入水分,颜料则不透明,可厚实堆叠出类似油画的效果。 在颜料的变化上,也有加入增厚剂或增光剂,提升颜料的光泽度及透明度。 毒性 丙烯颜料有轻微毒性。 清除方法 立刻用清水或肥皂水搓洗。 颜料干后,可用清水长时间浸泡,或于80摄氏度左右的热水浸泡后再搓洗。 溶于汽油。 Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water-soluble, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, mediums, or pastes, the finished acrylic painting can resemble a watercolor, a gouache or an oil painting, or have its own unique characteristics not attainable with other media. Painting with acrylics Before the 19th century, artists mixed their own paints, which allowed them to achieve the desired color and thickness, and to control the use of fillers, if any. While suitable media and raw pigments are available for the individual production of acrylic paint, hand mixing may not be practical because of the fast drying time and other technical issues, such as the necessity to combine several polymers, as well as surfactants, plasticizers, dispersants, defoamers and stabilisers in the correct amounts and order. Acrylic painters can modify the appearance, hardness, flexibility, texture, and other characteristics of the paint surface by using acrylic mediums or simply by adding water. Watercolor and oil painters also use various mediums, but the range of acrylic mediums is much greater. Acrylics have the ability to bond to many different surfaces, and mediums can be used to modify their binding characteristics. Acrylics can be used on paper, canvas and a range of other materials, however their use on engineered woods such as medium-density fiberboard can be problematic because of the porous nature of those surfaces. In these cases it is recommended that the surface first be sealed with an appropriate sealer. Acrylics can be applied in thin layers or washes to create effects that resemble watercolors and other water-based mediums. They can also be used to build thick layers of paint—gel and molding paste are sometimes used to create paintings with relief features. Acrylic paints are also used in hobbies such as trains, cars, houses, DIY projects, and human models. People who make such models use acrylic paint to build facial features on dolls, or raised details on other types of models. Wet acrylic paint is easily removed from paintbrushes and skin with water, whereas oil paints require the use of a hydrocarbon. Acrylic paints are the most common paints used in grattage, a surrealist technique that became popular with the advent of acrylic paint. Acrylics are used for this purpose because they easily scrape or peel from a surface. Painting techniques Acrylic artists' paints may be thinned with water or acrylic medium and used as washes in the manner of watercolor paints, but unlike watercolor the washes are not rehydratable once dry. For this reason, acrylics do not lend themselves to the color lifting techniques of gum arabic-based watercolor paints. Instead, the paint is applied in layers, sometimes diluting with water or acrylic medium to allow layers underneath to partially show through. Using an acrylic medium gives the paint more of a rich and glossy appearance, whereas using water makes the paint look more like watercolor and have a matte finish. Acrylic paints with gloss or matte finishes are common, although a satin (semi-matte) sheen is most common. Some brands exhibit a range of finishes (e.g. heavy-body paints from Golden, Liquitex, Winsor & Newton and Daler-Rowney); Politec acrylics are fully matte. As with oils, pigment amounts and particle size or shape can affect the paint sheen. Matting agents can also be added during manufacture to dull the finish. If desired, the artist can mix different media with their paints and use topcoats or varnishes to alter or unify sheen. When dry, acrylic paint is generally non-removable from a solid surface if it adheres to the surface. Water or mild solvents do not re-solubilize it, although isopropyl alcohol can lift some fresh paint films off. Toluene and acetone can remove paint films, but they do not lift paint stains very well and are not selective. The use of a solvent to remove paint may result in removal of all of the paint layers (acrylic gesso, et cetera). Oils and warm, soapy water can remove acrylic paint from skin. Acrylic paint can be removed from non-porus plastic surfaces, such as miniatures or models using certain cleaning products such as Dettol (containing chloroxylenol 4.8% v/w) An acrylic sizing should be used to prime canvas in preparation for painting with acrylic paints, to prevent Support Induced Discoloration (SID). Acrylic paint contains surfactants that can pull up discoloration from a raw canvas, especially in transparent glazed or translucent gelled areas. Gesso alone will not stop SID; a sizing must be applied before using a gesso. The viscosity of acrylic can be successfully reduced by using suitable extenders that maintain the integrity of the paint film. There are retarders to slow drying and extend workability time, and flow releases to increase color-blending ability. thermoplastic-polymer Polyethylene is a thermoplastic resin, which means an item made with the material can be recycled, melted down and reformed into another shape. Polyurethane, on the other hand, is a thermoset resin, meaning that it has two parts mixed together to form a chemical chain. Once polyurethane is cured, the process can’t be undone. This means that something made of polyurethane can’t be melted down and reformed into a different item. What is Polyurethane Foam? Polyurethane foam is one of the four basic types of products that can be made from raw, liquid polyurethane. They are comprised of two chemicals which, when mixed and heated, form liquid polyurethane prior to being further processed. These chemicals are polyol, a type of complex alcohol, and diisocyanate, a petroleum byproduct that reacts strongly with alcohol. By combining the two, a stable long-chain molecule is formed. It's a polymer, or plastic, known as urethane. What is Polyurethane Foam Used For? Polyurethane foam is used primarily for bedding and furniture stuffing. It's hypoallergenic, nontoxic and does not degrade over time. This means that cushions filled with it will always regain their shape, no matter what punishment they're put through. Foam beds are also becoming popular. The solid layer of foam molds to fit the body. Packing peanuts and foam inserts are also used by shipping companies across the world. How is Polyurethane Foam Made? Once the two ingredients have been combined to form hot liquid polyurethane, they are passed down through a pipe into a nozzle head. Beneath the head is a series of rollers upon which waxed paper passes by. The nozzle jets a fine spray of hot liquid over the waxed paper, mixing with blasts of carbon dioxide coming from another nozzle. This causes the polyurethane to expand as it moves down the conveyor belt, forming a foam strip. The edges of the foam are trimmed and compressed to ensure it retains a viable shape. The foam is comprised of an untold number of tiny gas bubbles trapped in the polyurethane. Unless the gas is released, the foam will take on the consistency of a rock. So, the foam passes beneath a series of heat lamps. It dries the foam and causes the bubbles to expand, then burst, leaving a completed spongy porous material behind. Urethane Vs. Polyurethane Although the terms "urethane" and "polyurethane" are often used interchangeably, these are two distinctly different compounds. Urethane Urethane is a crystalline compound with the chemical formula C3 H7 NO2. It is an ester of carbonic acid. Polyurethane Polyurethane is called such because it is composed of multiple, or “poly,” urethane units. The urethane units are joined by a chemical reaction called polymerization. Properties Urethane is flexible and malleable, making it ideal for objects that have different shapes and forms, and it is used in liquid form. Polyurethane, on the other hand, is stiff and rigid and is ideal for firmer items, with many advantages over natural rubber. Urethane Uses Many insecticides, veterinary medicines and pharmaceuticals contain different amounts of urethane. The compound is also used as a solvent. Some plastics are formed of urethane. Polyurethane Uses Polyurethane is used for solid materials such as shoes and foams. Some types of polyurethane are also mixed in paints for a long-lasting coating. Toxicity Urethane is toxic to small animals. People who take pharmaceuticals with urethane often experience nausea as a side effect. Polyurethane, on the other hand, biodegrades very slowly and generally poses a low toxic risk. What Is a Polymer? A polymer is simply a material composed of many repeated units called monomers that link together into chains or branches. Some polymers like starch, cellulose and rubber occur naturally while others like polyester, nylon and plastic are synthetic. What Makes Thermoplastic Polymers Special? The monomers that make up thermoplastic polymers come together via electrical bonds called van der Waals forces that weakly attract neutral molecules to each other. These repeating units arrange themselves in such a way that thermoplastic polymer molecules look like many strands of pearls mixed together. Because their bonds are weak, thermoplastic polymers readily soften when heated, allowing manufacturers to mold them into a wide range of shapes, then resoften them and mold them again. This ability to reuse thermoplastic polymers indefinitely means they are highly recyclable. Other benefits of these polymers include excellent strength and a tendency to resist shrinking. On the other hand, thermoplastic polymers do have a few drawbacks, including high production costs and the fact they melt easily, which renders them inappropriate for some high temperature applications. What Are Some Common Thermoplastic Polymers? There are actually many types of thermoplastic polymers, which are unique in form and function. Manufacturers often use high pressure polyethylene to encapsulate rigid objects like electrical equipment. Low pressure polyethylene is very elastic and ideal for insulating electrical cables. Polyamide is most commonly associated with the production of ropes and belts. Perhaps the most readily recognizable thermoplastic polymer is polyvinyl chloride, or PVC, which readily molds into pipes, containers and insulation materials. Finally, some adhesives are thermoplastic polymers, including acrylates, cyanoacrylates and epoxy. While thermoplastic polymers come in a wide range of formats and serve many unique purposes, the basic features of these materials remains the same: high versatility and recyclability. When it comes to chemistry applications in the real world, you would be hard-pressed to find a better example than the production of plastics, including thermoplastic polymers.

釉藥是什麼
釉藥與玻璃成分相近,
釉藥需燒附在坯體上,玻璃則可成形為獨立個體;
然而釉藥可增加陶瓷器的裝飾與保護效果,
得以盛裝水、食物或製成衛浴用品,
防止液體滲漏,讓表面容易清洗,
且由於釉色變化多端,讓陶瓷呈現多采多姿的面貌。

一般陶藝釉藥是由多種粉末原料組成,
如臺灣常見的長石原料為:日化長石、釜戶長石、澳洲長石、霞正長石...等,
再與其他原料,如石英、高嶺土、碳酸鋇、氧化鋅、石灰石、骨灰...等,
也會混和金屬氧化物:氧化鐵、氧化猛、碳酸銅、氧化鈷...等,
依重量比例調成,最後加入適量的水呈現液體狀態後,
使用浸、噴、刷、淋、彩繪等施釉技法,
讓坯體表面堆疊至適當的厚度層,
再經由每種釉藥適合的溫度燒成。

陶藝釉藥以溫度可區分為四個區塊
低溫釉 900~980℃
低中溫釉 1000~1160℃
中溫釉 1160~1280℃
高溫釉 1300以上℃,
通常鮮艷的釉色在低溫較容易保留,
但也較易釋放出金屬物質,
然而1200℃以上的釉藥較穩定,不會釋放金屬物質,
毛細孔變小,也不易沾黏汙垢。
柴燒窯內的火焰與坯體狀態,大約接近1000度。

影響陶藝釉藥的燒成氣氛
氧化燒
燒成時窯內充滿氧氣(空氣)的條件下燃燒加熱。
釉色穩定。例:結晶、銅綠、鐵紅...等釉色。
一般普通電窯(單純電熱絲加熱)。

還原燒
燒成時讓窯內氧氣(空氣)供應不足的條件下燃燒加熱,
轉而進入坯體與釉藥尋找氧氣燃燒。
釉色富變化,但較不易控制。例:青瓷、銅紅、鈞窯...等釉色。

瓦斯窯、柴窯、氧化還原兩用電窯。
瓦斯窯使用瓦斯燃燒,可看到火焰,控制空氣、壓力、氣壓...等狀態,來達到還原的效果。

備註:一般區分為氧化燒與還原燒,但另有中性氣氛,需視釉藥來決定。

Methods to recover the elasticity of silicone rubber

Heat treatment: Silicone rubber can lose its elasticity over time due to exposure to extreme temperatures or environmental factors.
By subjecting the rubber to controlled heat, you can restore its elasticity.
Place the silicone rubber object in an oven set at a low temperature, typically around 150-200 degrees Celsius (300-390 degrees Fahrenheit), for a specific period of time.
This process, known as heat treatment or annealing, helps to relax the polymer chains and restore the material's elasticity.
Be sure to consult the manufacturer's guidelines or perform a small test before exposing the entire object to heat.

Compression molding: Silicone rubber can be restored by subjecting it to compression molding.
This method involves applying pressure to the rubber to reshape and reform its structure.
Place the silicone rubber object between two heated plates or molds and apply pressure.
The heat softens the material, allowing it to flow and regain its original shape.
This process can help eliminate any deformations or stresses that may have caused the loss of elasticity.

Silicone rejuvenation products: There are silicone rejuvenation products available on the market that can help restore the elasticity of silicone rubber.
These products typically contain silicone oils or treatments that penetrate the rubber surface and replenish its lost elasticity.
Follow the instructions provided with the product for proper application and curing time.

Mechanical stretching: Gently stretching the silicone rubber can help restore its elasticity to some extent.
Take the rubber object and stretch it slowly and evenly in different directions.
This process helps realign the polymer chains and improves the material's elasticity.
However, be cautious not to overstretch the rubber, as it may lead to permanent deformation or tearing.

Remember to consider the specific properties and composition of the silicone rubber you are working with, as different formulations may require different approaches for recovery.
If you have valuable or critical silicone rubber components, it is advisable to consult the manufacturer or an expert in the field for guidance on the best method to restore elasticity.

ionocaloric refrigeration cycle

This is an advanced cooling technology that utilizes the ionocaloric effect, driven by an electrochemical field, to achieve efficient and eco-friendly refrigeration. By manipulating the electrochemical potential through ion addition or removal, significant temperature changes and entropy variations are achieved. This cycle offers a sustainable alternative to traditional refrigeration systems, with potential applications in various industries. Ongoing research is focused on optimizing ionocaloric materials and system design to enhance its performance and viability. It was developed by Drew Lilley and Ravi Prasher at the Department of Energy's Lawrence Berkeley National Laboratory. 离子取代冷媒 全新制冷技术问世,有望取代传统冰箱。 传统的冰箱利用液体吸收热量后蒸发成气体,再通过密闭管道冷凝回液体,以此循环来降低温度。 然而,目前常用的制冷剂对环境有害,因此寻找更环保、更安全的制冷方式,成为科学家努力的方向。 科学新闻网站《Science Alert》报道,科学家发明了一种全新的制冷方法“离子热循环冷却”(ionocaloric cooling),这项技术不仅更安全,还对环境更友善,未来可能彻底改变人们的制冷方式。 由美国劳伦斯柏克莱国家实验室与加州大学柏克莱分校的研究团队开发的这项新技术,运用了物质相变时储存或释放能量的原理。 就像冰融化时会吸收周围的热能一样,这项技术透过添加离子来改变物质的相态,进而达到制冷效果。 研究团队使用碘和钠制成的盐类来融化碳酸乙烯酯(一种常见于锂电池的有机溶剂)进行实验。 这种溶剂的生产过程需要使用二氧化碳,也说明有关系统不仅不会产生温室气体,还可能协助减少大气中的二氧化碳。 团队的实验结果令人振奋:仅需不到1伏特的电压,就能产生25摄氏度的温度变化,这个成果超越了目前其他类似技术的表现。 研究团队目前致力于将这项技术从实验室推向商业应用,并计划扩大规模。 这项技术未来不仅可用于制冷,还可应用于加热系统。

在半导体加工、表面处理和有害气体排放等许多工业领域都有应用。 microwave-plasmas comsol blogs 经微波技术激发的等离子体中。 等离子体和用于激发等离子体的磁控管不发生接触。 此等离子体密度和自由基的比例在微波等离子体中是非常高的。 借此,可实现特别高的蚀刻速率。 当电子从穿透等离子体的电磁波中获得足够的能量,微波等离子体就会持续放电。 微波等离子体的物理特性有很大不同,具体取决于传播的是 TE 模式(面外电场)还是 TM 模式(面内电场)。 在这两种情况下,电磁波都不可能穿透到电子密度超过临界电子密度的等离子体区域(2.45GHz 时约为 7.6×1016 1/m3)。 这个临界值对应于电磁波的角频率与等离子体频率相等的点。 微波等离子体的压力范围非常宽。 对于电子回旋共振等离子体,压力可以在 1Pa 左右,而对于非电子回旋共振等离子体,压力范围通常在 100Pa 到一个大气压之间。 功率在几瓦到几千瓦不等。 由于微波电源很便宜,所以微波等离子体很受欢迎。 微波放电理论 为了理解与微波等离子体仿真有关的细微差别,有必要复习一下如何维持放电的理论。 微波在时间尺度上的等离子体特性与较长期的等离子体行为是不同的,后者受双极场的约束。 ECR 反应器 当对 ECR(电子回旋共振)反应器进行建模时,问题的复杂性又增加了一层。 电子传递属性成为了静态磁通密度的张量和函数,而静态磁通密度可以用永磁体来创建。等离子体电导率也变成了一个完整的张量,并且是一个高度非线性的静态磁通密度的函数。 微波等离子体技术的应用 等离子体(plasma)是物质气体、液体、固体以外,存在的第四态,比气态能量更高,等离子体是良导体,受磁场影响。 微波是等离子体产生的方法之一,微波等离子体(microwave plasma)具有无电极、大面/体积、低能耗、高效率和低成本等多种优点,比之其它电激励类型的等离子体有更高的活性。 微波等离子体的运行气压很宽,从10-3Pa(微波ECR等离子体)到超过大气压(微波等离子体炬)。 微波等离子体技术的应用包括如下几个方向: 封闭式微波等离子体技术 微波等离子体无电极、大体积、运行气压宽、低能耗、高效率和低成本等优点,其等离子体发生室和处理室可分合,工艺灵活。 开放式微波等离子体技术(等离子体炬) 等离子体火炬(亦称等离子体发生器或等离子体加热系统)就是依据这一原理研制的专门设备。 等离子体火炬通过电弧来产生高温气体,可在氧化、还原或惰性环境下工作,可以为气化、裂解、反应、熔融和冶炼等各种功能的工业炉提供热源。 微波等离子体炬就是以微波为激发能量的开放式等离子体技术。 应用领域 石墨烯和新材料制备领域,化工和环保领域

清除固化油性胶

已固化的油性胶难以清除,需要使用化学溶剂软化及降解,配以机械方法除去。 丙酮、乙醇、阻燃剂和化学降解剂可以软化或降解部分油性胶。 步骤 1 使用丙酮或丙酮汽油混合液。 取丙酮或丙酮与汽油的混合比3:1的溶液,使用刷子涂抹在已固化油性胶上,5-10分钟后用刮板刮除。 2 使用乙醇或甲醇。 取乙醇或甲醇溶液,方法同上,用时间稍长,约10-15分钟。 乙醇甲醇对部分油性胶有一定溶解作用。 3 使用阻燃剂溶液。 取阻燃剂如溴代烃与汽油的混合比1:3的溶液,,方法同上,时间约10分钟。 4 使用化学降解剂。 选择适合油性胶的化学降解剂,按说明稀释后涂抹,作用时间较长,约0.5-1小时,然后清除。 5 使用高温水蒸汽。 使用热水蒸汽机喷射高温蒸汽对固化油性胶进行软化,然后用刮板刮除清除。 蒸汽温度控制在100°C,软化效果较好。 6 机械磨除。 如果化学方法不易除去,可以使用角磨机、气动除胶枪对固化油胶层进行机械除去。 这种方法需要适当控制以免损伤基材。 注意事项 控制化学药剂使用量和作用时间,蒸汽软化温度控制在100°C;机械除胶要轻轻操作。

溶解丙烯酸树脂

丙烯酸树脂用甲苯和酯类如丙烯酸丁酯溶剂可以溶解。 丙烯酸树脂,丙烯酸树脂是丙烯酸、甲基丙烯酸及其衍生物聚合物的总称。 其中的丙烯酸,它可与水、醇、醚和氯仿互溶。 用丙烯酸酯和甲基丙烯酸酯单体共聚合成的丙烯酸树脂对光的主吸收峰处于太阳光谱范围之外,所以制得的丙烯酸树脂漆具有优异的耐光性及抗户外老化性能。

丙烯酸树脂作为粉末涂料的用途

1、流平剂 使用最广泛的粉末涂料流平剂是丙烯酸树脂,代表产品是501,它们是丙烯酸均聚物或丙烯酸共聚物,如丙烯酸正丁酯均聚物,丙烯酸异辛酯均聚物,丙烯酸二酯与丙烯酸异辛酯共聚物,丙烯酸正丁酯与丙烯酸异辛酯共聚物等。 2、润湿剂(Weting Agent) 润湿剂又称光亮剂、增光剂,代表产品是701。 润湿剂通常是甲基丙烯酸甲酯均聚物或甲基丙烯酸甲酯-丙烯酸正丁酯共聚物,甲基丙烯酸甲酯-丙烯酸异辛酯共聚物。 因甲苯、二甲苯作溶剂溶液聚合,引发剂是过氧化二苯甲酰,聚合后,真空脱除溶剂,冷却后破碎,成产品。 3、热塑性丙烯酸粉末涂料 热塑性丙烯酸粉末涂料是由不含或含极少量活性官能团的热塑性丙烯酸树脂为成膜物的粉末涂料。 其优点是其优良的光学性能和保光性能,其缺点是附着力和机械性能不足,若分子结构中含有少量丙烯酸或甲基丙烯酸链节,可以提高其与底材或底漆的附着力。

胶水



常见的有瞬间胶 (常见的-1203瞬干胶-氰基丙烯酸乙酯强力瞬间接着剂是一种) 环氧树脂粘结类 厌氧胶水 UV胶水(紫外线光固化类) 热熔胶 压敏胶 乳胶类等。 胶水就是能够粘接两个物体的物质。 胶水不是独立存在的,它必须涂在两个物体之间才能发挥粘接作用。 胶水中的化学成分,在水性环境里。 胶水中的高分子体(白胶中的醋酸乙烯是石油衍生物的一种)都是呈圆形粒子,一般粒子的半径是在0.5~5μm之间。 原理 物体的粘接,就是靠胶水中的高分子体间的拉力来实现的。 在胶水中,水就是中高分子体的载体,水载着高分子体慢慢地浸入到物体的组织内。 当胶水中的水分消失后,胶水中的高分子体就依靠相互间的拉力,将两个物体紧紧的结合在一起。 在胶水的使用中,涂胶量过多会使胶水中的高分子体相互拥挤在一起,高分子体间就产生不了很好的拉力。 同时,高分子体间的水分也不容易挥发掉。 这就是为什么在粘接过程中“胶膜越厚,胶水的粘接效力越差”。 涂胶量过多,胶水大起到的是“填充作用”而不是粘接作用,物体间的粘接靠的不是胶水的粘结力,而是胶水的“内聚力”。 如果不是水溶性的,其实原理也大同小异,就是用其他溶剂代替了水罢了。

注意事项

环境 在使用条件胶水和密封胶水要在一定的环境中使用,工作条件对胶接性能有重要影响。 在使用条件中,有受力情况,环境温度和湿度,化学介质情况,户外条件等等。 (1)受力情况。 当被粘物受剥离力,不均匀扯离力作用时,可选用韧性好的胶,如橡胶胶水、聚氨酯胶等; 当受均匀扯离力、剪切力作用时,可选用硬度和强度较高的胶,如环氧胶、丙烯酸酯胶。 (2)温度情况。 不同的胶水有不同的耐热性。 根据不同的温度,选用不同的胶水。 (3)湿度。 湿气和水分对胶接界面的稳定性很不利,可以说是有害而无益的。 因为水分子体积小,极性大,经过渗透、扩散,起到一种水解作用,使胶接面破坏或自行脱开,造成胶接强度和耐久性降低。 被粘件要求耐水性好的,选环氧胶,聚氨酯胶等。 (4)化学介质。 化学介质主要指的是酸、碱、盐、溶剂等,不同类型的胶水,不同的固化条件,具有不同的耐介质能力。 所以,要根据被粘物接触的介质选用胶水和密封胶。 (5)户外条件。 户外使用的胶接件所处条件比较复杂,气温变化、风吹雨淋、日晒冰冻等,会加速胶层老化,使寿命缩短。 因此,在户外条件下,胶接要选用高温固化和耐大气老化好的胶,如酚醛一缩醛胶,环氧一丁腈胶; 密封则选用硅酮密封胶。 双组份聚氨酯胶粘剂 双组份聚氨酯胶粘剂良好的复合效果与多方面条件有关,其中工作环境的变化也是很重要的影响因素。 也就是说,随着季节气候的改变,为了获得理想的复合效果,有必要对胶水使用工艺作某些微调。 简单地说,影响复合的季节气候变化也就是环境湿度、温度两大指标的变化:具体而言在春夏两季尤其是梅雨时节,空气的相对湿度较大,甚至可达到饱和而秋冬两季则空气干燥、湿度小; 就气温而言,夏季比冬季高出许多,两者之间最大可相差将近30~40℃(此处以室内无暖气的南方地区为例来作比较)。 对于这些差异如不加注意,很可能在复合时会产生下列问题:空气潮湿时,胶水经常固化不彻底,也就是干不透,残留黏性大,严重的甚至可在对复合膜作剥离时观察到有拉丝的现象,特别当薄膜本身吸潮性较大,比如用尼龙膜复合时就更容易产生这种现象; 其次,潮湿的空气会在上胶网纹辊上产生冷凝,从而将水分带入到胶盆中,随着时间的推移,胶水逐渐由透明变得混沌、发白,以至失去粘结作用; 湿热高温亦使得胶水的保存比较困难,配好的工作胶液如当天用不完,放置过夜之后,经常会发白结块,形成凝胶(果冻啫喱状)。 与之相对的是,在冬季天冷时,之前没用完的工作胶液隔夜之后依然保持良好的透明流动性,甚至不必分批分次掺入新配的工作胶液内,就可直接拿来上机使用。 另一方面,在气温较低的冬季,胶水会变得粘稠,流平性下降。 当复合机高速运转时,胶盆内容易产生大量的气泡堆积在胶水表面以及上胶网纹辊边缘,这时有可能造成空泡转移,上胶量不足,影响复合牢度; 同时,由于流平分散性能不佳,复合膜的外观效果也会变差,比如胶水的流平纹比较明显,有时呈橘子皮状,当用于复合铝箔或镀铝膜时,如果印刷面有大面积的白墨或浅色油墨时,更容易形成小白点、斑点; 另外,由于冬季气温低,熟化房的温度与外界环境温度相差很大,如果保温措施做得不够到位,则热量的散失速度远比高温的夏季为快,这往往使得熟化房内温度达不到设置温度(一般为50℃)。 因此熟化的效果亦受到一定的影响,在同等的熟化时间下,复合牢度有可能比夏季时偏低一些。 分析造成以上现象的原因,就要了解水分和温度对胶粘剂的影响。 首先,对于双组份聚氨酯胶粘剂来说,水分如同其中的主剂即聚酯/聚醚多元醇一样,可与固化剂中的NCO基团反应。 据测算,1g的水可以消耗掉26~32g的固化剂,当然,这是就纯粹的反应重量比而言,在实际当中,混入工作胶液内的水分在与固化剂反应时是与主剂相竞争的。 但不管到底有多少水分参与了反应,这无疑是消耗了固化剂,使得其与主剂反应的量达不到原来设定的工作配比,因此也就造成了固化的不彻底和残留黏性。 而胶粘剂的粘度和反应活性则与温度有着很大的关联。 胶粘剂厂家给出的粘度值是以25℃为标准温度用旋转粘度计测量出来的,这意味着实际使用时,工作环境的温度在夏季可比其高出10余度,而冬季天冷时可能比其低上20℃有多。 胶水的粘度正好与温度高低相反,即同样的胶水在温度高时表现出来的粘度值较低,流动分散性能好,温度低则粘度高,流平差。 另外,胶粘剂的两个组份之间的交联固化反应,在温度低时反应速度慢,温度高时反应速度快,这也恰恰是要有熟化房的原因(加快固化反应速度,提高生产效率)。 针对这样的情况,在使用双组份聚氨酯胶粘剂进行复合时可根据环境变化做以下一些调整:如果空气潮湿,气温偏高,将固化剂的用量适当提高10%~20%,以弥补水分对其的消耗; 经常用干爽的棉纱或布碎吸掉复合机上冷凝的水滴,防止其落入胶盆内; 用不完的工作胶液可添加少量溶剂稀释,然后密封保管,如果条件允许,可置于小型冷柜内冷藏保管,这样效果更佳,下次再用时,在密闭情况下解冻,并与新配的工作胶液混合使用。 当冬季气温偏低时,配制工作胶液可适当多加一些溶剂以降低体系粘度,改善流平分散性,同时也减少了工作时胶盆内气泡的产生。 但这样做工作胶液的浓度会有所降低,如不欲改变工作浓度,则可以用少量的丙酮取代部分醋酸乙酯,即使用丙酮与醋酸乙酯的混合溶剂来作为稀释剂,两者的比例可为2:8或3:7。 此外,冬季低温时可把熟化房的温度设置稍为调高,以保证其实际温度能达到要求,以免影响熟化效果。 其他 粘度 胶水的粘度用布氏粘度计测出,单位是“cps厘泊”。 胶水的粘度的读数一般在300~30000cps之间。 在水溶性的粘合剂中,固体含量并不决定胶的粘度,而在于胶水的配方内的增塑剂、增粘剂等等,影响胶水的粘度值。 一般情况下周围的环境温度越高“粘度↓”,“温度↓粘度↑”。 水在27℃时的粘度为1。 粘接工艺 由于胶水和被粘物的种类很多,所采用的粘接工艺也不完全一样,概括起来可分为: ①胶水的配制; ②被粘物的表面处理; ③涂胶; ④晾置,使溶剂等低分子物挥发凝胶(只是限于一些特殊胶水,一般的胶水不用晾置); ⑤叠合加压; ⑥清除残留在制品表面的胶水(施胶时注意点这一步就可以避免)。 胶黏剂 凡是能把同种的或不同种的固体材料表面连接在一起的媒介物质统称为胶黏剂,通过胶黏剂的粘接力使固体表面连接在一起的方法叫做粘接或胶接。 数千年前,人类就注意到自然界中的粘接现象,例如甲壳动物牢固地粘贴于岩石上等。 自然界存在的粘接现象启发人类利用粘接作为连接物体的方法。 早期的胶黏剂都来源于天然物质,例如用来黏合箭头、矛头的松脂、天然沥青以及骨胶、石灰等。 在长期使用天然胶黏剂的时期,粘接技术未能得到显著的发展。 直到20世纪初,美国发明酚醛树脂开始,胶黏剂和粘接技术进入了一个崭新的发展时期,在人类社会中占有了重要的地位。 胶黏剂在国民经济各部门中都有着重大作用。 例如在航空航天工业、汽车及车辆制造工业、电子电气工业以及医学方面等都有着广泛的应用。 现代的航空工业大都使用高性能的酚醛-缩醛类结构胶黏剂。 制造每架飞机大约需要400~2200kg的胶黏剂,并且单机使用胶黏剂的数量常常代表一个国家飞机制造工业的工艺水平。 在电子、电气工业中,胶黏剂主要作为绝缘材料、浸渍材料和灌封材料投入使用,所用的胶黏剂大部分为改性环氧、酚醛-缩醛及有机硅聚合物方面的产品。 在医学方面,以各种丙烯酸酯聚合物或单体为基料的胶黏剂有广泛的应用,例如在施行各种骨折接骨手术、胸腔手术中的骨质粘接,皮肤破损的粘接及止血等都是重要的应用范例。

如何加温溶解环氧树脂胶

胶粘剂在工业生产中起着重要的作用,而环氧树脂胶作为一种常用的胶粘剂,具有优异的性能和广泛的应用领域。 然而,在使用环氧树脂胶时,有时会遇到需要加温溶解的情况。 那么,环氧树脂胶如何加温溶解呢?下面我们来详细介绍。 环氧树脂胶的性能 环氧树脂胶是一种由环氧树脂和固化剂组成的胶粘剂,具有优异的粘接强度、耐化学腐蚀性和耐高温性能。 在一些特殊情况下,环氧树脂胶可能会因为低温或长时间存放而变得粘稠或凝固,无法正常使用。 这时,我们可以通过加温溶解的方法来恢复其流动性和粘接性能。 加温溶解环氧树脂胶的方法有多种,下面我们介绍其中两种常用的方法。 第一种方法是使用热水浴。 将需要加温溶解的环氧树脂胶放入一个耐热容器中,然后将容器放入预先加热好的热水中。 注意,热水的温度应该控制在环氧树脂胶的溶解温度范围内,一般为50℃-80℃。 通过热水的传导热量,环氧树脂胶会逐渐溶解并恢复流动性。 在加热过程中,可以用玻璃棒或搅拌棒轻轻搅拌,促进溶解的进行。 当环氧树脂胶完全溶解后,可以取出容器,待其冷却后即可使用。 第二种方法是使用加热器。 将需要加温溶解的环氧树脂胶放入一个耐热容器中,然后将容器放入加热器中。 加热器可以是电热板、电热套或电热棒等。 通过加热器的加热作用,环氧树脂胶会逐渐溶解并恢复流动性。 在加热过程中,同样可以用玻璃棒或搅拌棒轻轻搅拌,促进溶解的进行。 当环氧树脂胶完全溶解后,可以取出容器,待其冷却后即可使用。 需要注意的是,在加温溶解环氧树脂胶时,要控制好温度加热时间,避免过高的温度或过长的加热时间导致环氧树脂胶的性能发生变化。 此外,加温溶解后的环氧树脂胶应尽快使用,避免再次凝固。 世盈胶水

洗掉502胶水

第一种、这是最简单的一种,直接用湿毛巾敷在胶渍处,一段时间后502就会变软,然后洗掉就可以了。 第二种、在沾有502胶渍的地方使用同样的502进行融化,变软后去除。 第三种、使用绝缘油,绝缘油效果很好,502胶水能很快变软,然后直接洗掉就可以了 第四种、使用丙酮,但是使用丙酮一定要注意,丙酮有一定的毒性,它会对眼睛造成很大的刺激,如果不小心进入到了眼睛,立即用大量清水清洗,清洗时可以使用稀碳酸氢钠溶液。 第五种、用热水浸泡一下也可以,只需要泡5-10分钟即可。 【衣服被502胶水沾上的去除方法】 在使用502胶水的过程,衣服无疑是很容易被沾上胶水的,那么衣服沾上502胶水怎么洗掉,有哪些方法呢。 第一种、用香蕉水滴在衣服的502胶渍上,接着用刷子不停的对着胶渍刷,一段时间之后,胶会变软从衣物上脱落,这时再用清水漂洗,然后晾干就可以了。 第二种、因为502胶的溶剂是丙酮,只要沾染了502胶的衣物不含有醋酸纤维,就可以使用丙酮进行清洗,因为502胶粘在醋酸纤维上的话,纤维会被溶解,便会造成破洞,在用丙酮要非常注意使用方法: a、首先把衣服翻转到背面,渍迹下面垫上卫生纸等吸附材料。 b、将丙酮滴在渍迹周围,由外向内逐步溶解,如果你觉得速度慢的话,还可以垫上一层布轻轻挤压、敲打。 c、更换吸附材料,重复上面的操作,直至全部溶解完毕。 第三种、在衣服上沾有502胶渍的地方使用同样的502进行融化,,然后迅速用水洗掉,就可以了。 第四种、使用绝缘油,但是比较难找到绝缘油,在变压器里一般有,绝缘油效果很好,502胶水能很快变软,然后直接洗掉就可以了。 第五种、其实,如果只是很小面积粘上502胶水,用热水浸泡一下也可以达到去除的效果,当然如果是大面积沾上502胶水,就要涂上丙酮了,这是最好的去除方法。 【日常502的去除方法】 1、以毒攻毒法 如果要是比较硬的地方切不怕水的地方沾上了502胶水,可以再远地方再滴上一些502胶水,然后迅速的用水洗掉。 2、绝缘油 用绝缘油,倒点变压器里的绝缘油在桌上,502胶水很快变软,可以很快搓掉了。 3、溶解法 502胶水是一种树脂胶,只要用溶解树脂的有机溶剂就可以,比如丙酮。 大约等5~10分钟就可以除去。 (但吸入丙酮有毒,注意使用方法)可以把粘胶的部分塞到瓶子里。 据说放到冰箱中冷冻,胶也会掉下来。 要是使用丙酮清除衣物上的胶水,先要确定衣物不含有醋酸纤维,才可以使用丙酮,如果面料是全醋酸纤维织品,渍迹处的纤维就会溶解成为破洞而无法修复。 4、香蕉水 用香蕉水滴在胶水渍上,同时用旧牙刷不断搅刷,待胶水迹变软脱下,再用清水漂净,反覆刷洗,刷净为止。 不过这个方法也不是很灵,有些地方好像用着也是无效的。 5、热毛巾法 可以用湿的热毛巾在粘502那里。 十几分钟后固化的502就会变软,就可以清除了。 1、502胶水有毒吗 502胶水属于化学制品,对人体是有一定伤害的,但就平时的使用量,还不致对人造成伤害,而且它一旦固化,就没什么毒性了。 2、502胶水耐高温吗 502胶水并不耐高温,甚至可以说在100高温下即能快速软化。 所以502胶水的使用说明中会有“25度以下储存”字样。 3、502胶水的正确使用方法 第一、先把要使用胶水粘黏的物品表面清理干净,去除表面灰尘等。 第二、打开前盖,并以手指轻扣尖端部份,使不留有残余液体,再用剪刀剪出孔穴。 第三、在要粘黏的地方滴一小滴,立即进行接着,并保持至硬化为止,接着面积能太大,厚度也不能超过0.2mm。 第四、用完后,立即将盖子盖上,然后存放于阴凉干燥处或冷藏,注意,千万不能倒置。 4、502胶水使用注意事项 第一、因为502胶水的蒸气会刺激粘膜及眼睛,所以在打开瓶帽时一定要远离眼睛。 第二、使用期间要对自己的皮肤做好防护工作,避免与皮肤接触及进入眼睛,若不小心进入眼睛,立即以大量清水洗涤并送医。 用绝缘油,倒点变压器里的绝缘油在桌上,502胶水很快变软,可以很快搓掉了。 那么假如不小心把502胶水弄进眼睛里,又该怎么处理呢? 方法一: 有条件的可以用生理盐水冲洗(药店有售),一般用大量清水冲洗干净也可,不多的胶水可以通过水冲洗干净,如果与角膜有粘连,最好到医院用针头剔除干净,滴消炎的眼药水治疗。 方法二: 立即用热水或丙酮清洗,需要去眼科给予结膜囊冲洗加棉签擦拭。 裂隙灯观察角膜情况,清除胶水残留。 给予抗生素眼药水。 来不及去医院,抓紧时间就近取干净的凉白开水加少量盐,大量冲洗,将有害物稀释到最低浓度,实在紧张,也可以用自来水冲,提起眼脸,再到医院就医,点抗生素眼药水即可。
