造纸工业消泡剂的概述
造纸行业泡沫处理在生产中是不可避免而且相当棘手的一个问题。从制浆过程中,都有不同程度的泡沫。泡沫严重影响了纸张的正常生产和纸张质量。造纸消泡剂可以完全解决消泡问题。传统消泡剂主要是矿物油,磺化植物油,醇类等表面活性差,消泡效率很低,适用面较窄的消泡剂,不能满足大部分用户的要求。为了适应市场变化,脂肪酸酰胺消泡剂、聚醚消泡剂,有机硅消泡剂等随后出现。 1脂肪酸酰胺消泡，脂肪酸酰胺消泡剂为合成消泡剂是一种合成的消泡剂,无毒且流动性较好易于使用,便宜,主要用于制浆和抄纸的部分。
2聚醚消泡消剂的主要活性成分是环氧乙烷-环氧丙烷嵌段共聚物。主要用于造纸涂布纸涂料配置的过程中,由于聚醚消泡剂仅消泡性能卓越，还可以长久的抑泡。聚醚消泡剂也广泛应用于激光、日用化工、纺织助剂、石油、食品,在橡胶工业也有着重要的应用。
3有机硅消泡剂通常包含含有硅油和乳化剂两种成分,两者缺一不可。常用的硅油是二甲基硅油或硅膏(二甲基硅油和改性二氧化硅)。
Papermaking industry overview of defoaming agent
Papermaking industry foam processing in production is inevitable and quite difficult a problem.From pulping process, has a different degree of bubbles.Bubble seriously affected the normal production of paper and paper quality.Papermaking defoamer can completely solve the problem of foam.Traditional defoaming agent mainly mineral oil, sulfonated vegetable oils, alcohols, such as surface activity is poor, defoaming efficiency is very low and narrow applicable defoaming agent, can't meet the needs of most users.In order to adapt to market changes, fatty acid amide defoaming agent and polyether defoaming agent, silicone defoaming agent and so on appears in the later.
1 fatty acid amide defoaming, fatty acid amide defoaming agent for the synthesis of defoaming agent is a kind of synthesis of defoaming agent, non-toxic and has good liquidity is easy to use, cheap, it is mainly used for pulping and the writing section.
2 polyether defoaming agent elimination is the main active ingredient of epoxy ethane - epoxy propane block copolymer.Mainly used in the process of paper coated paper coating configuration, because only polyether defoaming agent defoaming
performance is outstanding, also can inhibit.Polyether defoaming agent is widely used in laser, daily chemical industry, textile auxiliaries, oil, food, also has important applications in rubber industry.
3 organic silicon defoamer usually contains containing silicone oil and emulsifier two ingredients, both be short of one cannot.Common silicone oil is dimethyl silicon oil or cream (dimethyl silicone oil and modified silica).
DE feng papermaking, many different kinds of defoaming agent such as
papermaking black liquor defoaming agent, paper pulp and paper coating defoamer, defoaming agent in paper making water treatment, etc., can also call my company according to the different foam system to customize various defoaming agent.
