Shanghai Daoqin Plastics Co., Ltd.

         in plastics film processing and use process in need add plastics additives, is is has resin or film product solid has property can 不适应 its processing process requirements, add additives can its processing property;也 has material processing properties relatively good, product property can 却达不 to requirements, this need add additives, 以改变 product property can. 而开口 agent positive is film additives 之一, below/following, will is detailed introduction.

        现 in commonly used 开口爽 slip agent anti viscous agent has types: acid amine, acid amine, oxidation silicon; remove additives outer also has 开口母 material and slip masterbatch and other functional masterbatch.

        爽 slip agent: in film in add slip formed good in block between add water, can very easy sliding film, very difficult it separation 开;

        开口 agent: in film in add 入开口 agent or 开口母 material good use 砂纸 两 block between surface 打毛糙, this very easy film separation 开, is very difficult sliding;

        开口母 material: formed is silicon type (无 machine material);

        爽 slip masterbatch: formed amine type (has machine material). will amine and anti viscous agent 共同添 add to masterbatch in, formed 20~30% content, formed is 极佳 开口 masterbatch product.

        三 types slip agent introduction

        1, 油 acid amine:

        油 acid amine also 称油酰 amine, add amount is 0.1-0.15%, in processing must mixed combined material or masterbatch 形式添 add, ensure 均一 爽 slip 效果.

         in polyethylene (PE) film in use it can decrease/reduce processing process in inner scratch film and equipment between scratch, demolding easy, from increase output/production volume, improvement products surface gloss. acid amine for PE开口效果 good, 但味道 large, fast, effect/influence electrical and printing, especially is for/regarding temperature degree requirements comparison 严格, in and use amount different. generally 说, acid amine to surface fast, acid amine long friction coefficient ratio acid amine low, but also ratio acid amine heat stabilized property good.

        2, acid amine

         can use 做CPP, BOPP, LDPE, LLDPE, EVA, PVC, PVDF, PVDC, PU and metallocene polyethylene (PE) and other plastics film. through reduce products (film or sheet/slice 材) surface and friction coefficient, improve/increase film easy processing property and packaging as efficiency, add amount is 0.12% left right.

        芥 acid amine slip property strong/high, amount less, resistant temperature high, easy 变黄, ratio acid has obvious advantages.

         as is BOPP agent, its packaging speed degree can high separation 钟500～800包, its scratch 因数必 must ≤0.2, has add acid amine (0.12% left right), can obtain 准确 静, scratch 因数.

         remove mono use, also can production for slip property requirements very high PP吹胀 film, can using/adopting acid amine and acid amine mixed combined use, more is 理想.

        3, SiO2 anti-blocking agent

         this type of agent can very good maintain film high light property, tool has very strong/high anti-blocking property strong/high and dispersion property, can uniform dispersion in film in, in film surface formed many micro fine hard 突起, from decrease small film between 接触面积, achieve reduce film surface friction coefficient 目, make film easy 于开口, meanwhile due to this 突起 存 in, make external gas easy 于进入 to film between, in 两层贴 combined in film between formed true 空, from to anti film viscous function.

         can used for PP, PE and other film product.

        开口 agent selection

         in 开口爽 slip masterbatch in, amine and oxidation silicon selection is non important.

        酰 amine quality 参差不齐, masterbatch for film effect/influence has 发生, ratio 如味道 large, film upper has black spots and other, is due to material 油杂质 more, content pure 导致. in selection process in according to amine property can testing and use 情况决定.

        二 oxidation silicon selection separation important, need from 粒径, ratio surface 积, water amount, surface treatment and other more 方面考虑, for/regarding production masterbatch and film process has important effect/influence.
