年产1500吨醋酸乙烯乳胶漆的生产工艺
——溶解釜的设计
摘要：聚醋酸乙烯乳胶漆作为一种水性涂料，它的出现和发展适应了改善人类对生存环境的要求。它是白色粘稠液体，可加入各色色桨配成不同颜色的涂料。主要用于建筑物的内外墙涂饰，还可以用作金属表面的涂饰。该涂料以水为溶剂，所以具有安全无毒、施工方便的特点，易喷涂、刷涂和滚涂，干燥快、保色性好、透气性好。聚醋酸乙烯乳胶漆采用乳液聚合的生产工艺。乳液聚合的基本工艺有间歇聚合、半连续聚合、连续聚合、预乳液以及种子乳液聚合等。半连续分批加料乳液聚合能很好地控制聚合速度和操作弹性，且适应性强，单体转化率高（﹥99﹪），乳液性质稳定。该生产工艺目前还是工业化生产聚醋酸乙烯乳胶漆的主要方法。

1500Tons of Vinyl Acetate
Emulsion Paint Production Process
Dissolve The Axe- Design
Abstract: As a kind of coating, the polyvinyl acetate emulsion paint appears to the development and improvement of the living environment of mankind. It iswhiteviscous liquid, can add different colors of color of the paint. It is mainly used for building exterior daub and can also be used as a metal surface finishing. This coatingwithwater for solvent, so is non-toxic, convenient
construction, easy spraying, brush and roll, fast drying, it good, good permeability. Polyvinyl acetate emulsion paint by emulsion polymerization process. The basic technology of emulsion polymerization is intermittent polymerization, the semi-continuous polymerization, continuous emulsion polymerization, such as seed emulsion polymerization. The semi-continuous partial charging emulsion polymerization can easily control polymerization rate and elasticity of operation, and high adaptability(﹥99﹪), monomer latex properties stable. The production technology or industrial production according to the main method of emulsion paint ofvinyl acetate.
Keywords: emulsion paint, Dissolve The Axe, half a continuous emulsion polymerization, partial charging
