Shanghai Daoqin Plastics Co., Ltd.

       一, processing process 方面

       1, requirements 塑化一定 need high, 塑化尽 amount high, need separation understanding color can improve/increase 塑化, make material dilute soft degree versus for high 点;

       2, machine 筒四区 temperature degree, generally control in 175即 can.

       二, formulation 方面        

        1, for/regarding stability property need versus for good, can use stabilizer, is stability generally use lubricated 太差. but also content comparison large;        

        2, amount decrease/reduce lubricated separation 数, this product to outer force deformation 时候, PVC separation 子链连接不容 easy to bad;       

        3, inner lubricated amount less use, use large separation structure high melting point oxidation wax;

        4, need use high content CPE, 当CPE use amount increase high rear effect/influence tube/pipe hardness;

        5, need hardness very high, strong/high degree obvious 两 并存, powder amount need ultra- 25份;

        三, equipment 方面

        1, has 效平直段, amount use 2. 5倍 low. this pressure degree can increase very more,

        2, has 效平直段 front 端, can increase add pressure 仓.

        3, production process in, in 观察孔看 to 塑化也 good, inner outer lubricated 也适当, quality also is 不行, need more screw and material 筒.

        四, material amount

        1, improve/increase in short time inner mixed combined degree. requirements material amount resin flow;

        2, powder requirements 沉淀体积2.6-3.0以 inner,, use amount ultra- 25份, can in 掺入适 amount nano 钙 提 high strength;

        3, stabilizer selection very important, need has good heat stabilized property can, inner outer lubricated balanced stability. use amount ultra- 3.2份;

        4, CPE requirements molecular weight large, chlorine content standards, ultra- 35%, 且不残留, use amount is 5-7;

        5, lubricated must good, outer slip most use to PE腊, use amount and is 1.5份;

        6, if stability can a small amount of metal type;
