简介  稀释剂也叫“填充剂”。把原药加工成粉剂时,或为了使其便于喷施所加入的进行稀释的惰性物质。如:粘土、高岭土、陶土、滑石粉等。 稀释剂概述  热固性树脂需加入稀释剂来降低它的粘度而便于进一步加工,这些稀释剂实际上都是比树脂便宜的有机溶剂,因此也起降低加工成本的致廉作用。例如,环氧树脂常加的非活性稀释剂有丙酮、甲乙酮、环己酮、苯、甲苯、二甲苯、正丁醇、苯乙烯等。对热塑性树脂来说,加入溶剂的目的主要是工艺上的要求,因溶剂的加入可作为降低聚合物粘度的临时措施,以便把聚合物加工成制品——如合适的溶剂可以溶接聚合物而起粘合作用、聚合物的溶液可作涂料用、湿法纺丝也要加入溶剂才行。 但聚合物的溶解特性与小分子化合物有很大差别:蔗糖这类低分子量结晶物存在一个溶解极限——以每升溶剂中的可溶蔗糖克数表示;但对无定型聚合物而言,它的溶解性通常不存在极限,即它可与溶剂以任何比例相溶。 聚合物溶解的实质可理解为聚合物分子链段间由热运动所致的“孔隙”立即为更易活动的溶剂分子所占据,这个过程能继续到所有的聚合物分子被相互间隔而成为“溶液”。溶解聚合物的过程也可看成是一种受控的扩散过程,有时认定性的概念看可以说是聚合物溶解了溶剂而不是相反。 如果聚合物分子是交联的,则链段的运动受到限制,一种轻度交联的聚合物会溶胀或稍溶于溶剂,直到渗透力或扩散力为聚合物伸展着的分子的弹性收缩力所平衡,但它不会溶解成为一种易动的溶液。高度交联的聚合物不会发生链段运动,也不会吸收这种液体,故不可能溶胀或部分溶解。对可溶聚合物通常存在临界的溶解温度,低于该温度体系被分隔成两相:不溶性的溶胀聚合物和几乎是纯的溶剂。 聚合物溶剂中常可加入多量的非溶剂而不沉淀出聚合物。事头上加入这些非溶剂可改善溶解性,它们常被称为潜溶剂。往往存在这样的情况:二种非溶剂的混合物却是某聚合物的良溶剂,如硝酸纤维素的溶剂是醚—醇混合物,而相反的情况也存在,如醋酸纤维可分别溶解于苯胺或强酸,但不溶于它们的混合物。 增加粉状聚合物溶解速度的最有用办法:一是先把粉状料悬浮于非溶剂中,然后再加入真溶剂,这种操作过程可预防聚合物颗粒之间的结聚;二是用加热来加速溶解速度。 中国通用稀释剂常用对应牌号: x-1:·硝基漆稀释剂 x-3:过氯乙烯漆稀释剂 x-4:酚醛漆稀释剂 x-5:丙烯酸漆稀释剂 -6:醇酸漆稀释剂 x-7:环氧漆稀释剂 x-9:酚醛漆稀释剂 x-13:有机硅漆稀释剂 常见稀释剂  香蕉水又名天那水,主要成分是乙酸异戊酯,挥发性极强易燃易爆有毒,是危险品,主要是因为有较浓的香蕉气味,所以叫香蕉水。将乙酸乙酯、乙酸正丁酯、苯、甲苯、丙酮、乙醇、丁醇按一定重量百分组成配制成混合溶剂,称之为香蕉水。纯香蕉水是无色透明易挥发的液体,有较浓的香蕉气味,微溶于水,能溶于各种有机溶剂,易燃,主要用作喷漆的溶剂和稀释剂。香蕉水配制方法:按重量比,取乙酸正丁酯15%,乙酸乙酯15%,正丁醇10~15%,乙醇10%,丙酮5~10%,苯20%,二甲苯20%,然后将其充分混匀即可制得香蕉水。常见用来做家具漆、物品漆和汽车漆的稀释剂。 常见稀释剂简介515-稀释剂  1.稀释剂外观:无色透明液体。 2.稀释剂性能:丝网油墨标准稀释剂,略带清香味,挥发速度较快.稀释剂用途:稀释丝印油墨、移印油墨及清洗网版用。 616-慢干稀释剂  1.稀释剂外观:无色透明液体。 2.稀释剂性能:丝网油墨慢干稀释剂,干燥速度较慢,有助于油墨的消泡,流平及增加亮光,有效防止堵网。 3.稀释剂用途:稀释丝印油墨、移印油墨。 UV-SG稀释剂  1.UV-稀释剂外观:无色透明液体。   2.UV-稀释剂性能:属UV类稀释剂,可有效降低UV油墨的粘度。   3.UV-稀释剂用途:UV油墨通用稀释剂,加入量为油墨重量的5-10%。   4.UV-稀释剂UV固化速度:中等。 PP-处理水  1.PP处理水外观:无色透明液体。   2.PP处理水性能:通过对PP及PP和PE混合材料的表面擦拭处理,可明显提高油墨的附着力。代替火焰处理方式。   3.PP处理水用途:PP及PP和PE混合材料的表面擦拭处理 416-开油水 436-开油水  1.开油水外观:无色透明液体。   2.开油水用途:YPS和PS油墨专用稀释剂,防止油墨烧面。 UV-SL稀释剂  1.UV稀释剂外观:无色透明液体。   2.UV稀释剂性能:属UV类稀释剂,可有效降低UV油墨的粘度。   3.UV稀释剂用途:UV油墨通用稀释剂,加入量为油墨重量的5-10%。   4.UV稀释剂UV固化速度:中等。 UV-SB稀释剂  1.UV稀释剂外观:无色透明液体。   2、UV稀释剂性能:属UV类稀释剂,可有效降低UV油墨的粘度。   3.UV稀释剂用途:UV油墨通用稀释剂,加入量为油墨重量的3-5%。   4.UV稀释剂UV固化速度:较慢。 UV-SW稀释剂  1.UV稀释剂外观:无色透明液体。   2.UV稀释剂性能:属UV类稀释剂,可有效提高UV油墨的固化速度,提高油墨的硬度和耐化学性。   3.UV稀释剂用途:UV油墨通用稀释剂,加入量为油墨重量的3-5%。   4.UV稀释剂UV固化速度:快速。 LD减粘膏  1.减粘膏外观:半透明果冻状膏体。   2.减粘膏性能及用途:调入丝印或移印油墨中,可有效降低油墨的粘度,消除拉丝性,并有效提高印刷图文的立体感和清晰度,   加入量为油墨重量的5-25%,加入后和油墨充分搅拌均匀即可使用,可替代溶剂型稀释剂。 UV减粘膏  1.UV减粘膏外观:半透明果冻状膏体。   2.UV减粘膏性能及用途:调入UV丝印或移印油墨中,可有效降低油墨的粘度,消除拉丝性,并有效提高印刷图文的立体感和清晰度,加入量为油墨重量的3-5%,加入后和油墨充分搅拌均匀即可使用。

Introduction the diluent is also called "filler". The raw materials processed into powder, or to make it easy for spraying the addition of inert material dilution. Such as: clay, kaolin, clay, talc powder etc.. Diluent overview of thermosetting resin need to add thinner to reduce its viscosity and facilitate the further processing, these diluents are actually cheaper than organic solvent resin, therefore also reduce processing costs caused by low effect. For example, non reactive diluent of epoxy resin often with acetone, methyl ethyl ketone, cyclohexanone, benzene, toluene, xylene, butyl alcohol and styrene. The thermoplastic resin, adding solvent is the main purpose of the technological requirements, because the addition of solvents can be used as a temporary measure to reduce the viscosity of polymer, in order to put the polymer processing into products -- such as the suitable solvent can be welding and adhesive effect of polymer solution, polymer can be used as a coating for wet spinning, also want to join solvent caixing. But the dissolution properties of the polymer and small molecule compounds have very big difference: sucrose in this kind of low molecular weight crystalline substance there exists a solubility limit - per liter solvent soluble sucrose grams said; but for amorphous polymers, its solubility is not usually has a limit, that it can be in any ratio and solvent phase soluble. The solvent molecules occupy the essence of polymer solution, can be understood as the polymer molecular chain segment by thermal motion induced by the "pore" immediately for more mobile, this process can continue to polymer molecules all are mutually spaced but become "solution". The process of dissolving a polymer can also be seen as a diffusion process in a controlled, sometimes identified the concept can be said is a polymer dissolved solvent instead of. If the polymer molecules are cross-linked, then the chain segment movement is restricted, a lightly crosslinked polymers can swell or slightly soluble in the solvent, balance the shrinkage force of the elastic molecular until penetration or diffusion capacity for polymer stretched, but it will not be dissolved in a solution of a mobile. Not highly cross-linked polymer chain segment motion occurs, will not absorb the liquid, so it is not possible or partially dissolved swelling. The soluble polymers usually exist dissolved the critical temperature, lower than the temperature of the system is divided into two phases: not soluble swellable polymers and almost pure solvent. Non solvent volume can often polymer solvent without precipitation of polymers. Things head add these non solvent can improve the solubility, they are often referred to as the latent solvent. There are often such a situation: a good solvent two is a mixture of non solvent of polymers, such as cellulose nitrate solvent is ether alcohol mixture, whereas the opposite situation exists, such as cellulose acetate were dissolved in a mixture of aniline or strong, but insoluble in their. The most useful way to increase the dissolution rate of powder polymers: one is to put the powder material is suspended in a non solvent, then adding true solvents, this procedure can prevent between polymer particles.; the two is to use heat to accelerate the dissolution velocity. China General diluents commonly used corresponding brands: X-1: lacquer thinner x-3: Vinyl perchloride paint thinner x-4: phenolic paint thinner X-5: thinner acrylic paint -6: alkyd paint thinner X-7: epoxy paint thinner X-9: phenolic paint thinner X-13: silicone paint diluting agent common diluent water, is the main component of isoamyl acetate the volatile highly inflammable, poisonous, dangerous goods, mainly because of the thick banana smell, so called banana water. The ethyl acetate, butyl acetate, benzene, toluene, acetone, ethanol, butanol formed according to a certain weight percentage is formulated into a mixed solvent, known as banana water. Pure water is colorless and transparent banana volatile liquid, has the thick banana aroma, slightly soluble in water, soluble in various organic solvent, flammable, mainly used as paint solvents and diluents. Preparation method of banana water: according to the weight ratio of butyl acetate, take 15%, ethyl acetate and n-butanol 15%, 10 ~ 15%, 5 ~ 10% of 10% ethanol, acetone, benzene 20%, 20% of xylene, then mixing evenly to obtain banana water. The common used to make furniture paint, paint and paint thinner automobile articles.
