该指标属于必检项目,其数值反映了聚氯乙烯树脂的平均分子量大小,也就是案

分子链的长短,决定了树脂的牌号和相应
加工参数,聚氯乙烯树脂是一种非结晶的线型高分子化合物,其分
子量越大,数就越高,材料的强度、刚度、初性、热及耐低温
性越好,但成型加工性能越差,究其原因,主要是随聚氯乙烯树脂
分子量增加, 大分子链间范德华引力或绕程度相应增加
(对于悬浮法聚氧乙烯,分子量是聚合温度的函数),使其材料力学
性能提高,分子链中不正常的弱结构及链端基结构相应减少,故材
料热及时候性提高安装专用工具

除了以上的常用工具外,为保证安装质量,提高安装速度,还需下面三种专业工具。

l 压痕器   

用它来对外墙挂板的切割边进行压痕。这种压痕用于门窗

洞口以及其它洞口下、檐口或墙顶的 后一块挂板。压痕的作

用是将墙板咬合于收口条内。

l 钉槽冲孔器   如果有必要钉住墙板的切割边,就用这种工具来冲孔。考虑到       

挂板的胀缩,钉槽一般均为细长孔. 

l 拆除工具                                              

使用这种工具来拆除或替换墙板。                                      


The measurement of viscosity is usually carried out by Utrecht viscosimeter

This index belongs to the item that must check, its numerical value reflected the average molecular weight size of polyvinyl chloride resin, namely case

Vinyl chloride molecular chain length, determines the resin brand and corresponding

Processing parameters, polyvinyl chloride resin is an amorphous linear polymer compound, its component

The larger the quantity, the higher the number, the strength, stiffness, initialness, heat and low temperature resistance of the material

The better the properties are, the worse the molding properties are

With the increase of molecular weight, the degree of van der Waals attraction or winding between vinyl chloride macromolecules increases correspondingly

(for suspension polyethylene oxide, the molecular weight is a function of the polymerization temperature) to make its material mechanics

The abnormal weak structure and chain end - group structure decrease with the increase of molecular performance

Improve material heat and timeliness and install special tools

In addition to the above commonly used tools, in order to ensure the installation quality, improve the installation speed, also need the following three professional tools.

L indentation

It is used for indentation on the cutting edge of exterior wall panels.This indentation is used in doors and Windows

The last board under the eaves or on the top of a wall under the mouth of a cave or other opening.The indentation

It is used to bite the wallboard into the seam strip.

Slotted punch if it is necessary to nail the cutting edge of the wall panel, use this tool to punch.Considering the

Board expansion and contraction, nail slot are generally slender hole.

L removal tools

Use this tool to remove or replace siding.
