Stone-plastic line as elevator sleeve is now more and more accepted and promoted by more and more customers. In the process of more and more products being used, there will be some quality accidents more or less. If the factory is regular and the workers receive strict quality inspection training and then go on duty, they will generally take one of the occurrences in the production process of stone-plastic line. Some common faults of finished products have been avoided, but if there is no formal training in this area, it is easy to produce quality batch accidents. As an old driver who is very professional in making stone-plastic lines (elevator sleeves), the following is an analysis of several common faults that often occur in stone-plastic lines (elevator sleeves).


First, the toughness of the line is poor, the base material is brittle and easy to break.


1. The number of calcium powder is too low. We usually use 600-purpose heavy calcium to make stone-plastic lines. The lines made by this kind of calcium powder are delicate in texture, smooth in surface and will not have some small bumps of impurities. On the contrary, if some calcium powders with a lower number of items are used, the texture of the lines will be brittle and the toughness will be worse.


2. There is no use of PVC resin powder raw materials, the selection of some official materials, plastic steel materials. In the process of recycling, the product toughness is getting lower and lower.


3. The quality of chemical small materials is not up to the standard. In the plasticizing process of raw materials for stone and plastic lines, stabilizers, CPE and other small chemical materials play a decisive role.


4. The physical reason is that in order to reduce costs, individual manufacturers open the die too thin, resulting in light weight and easy to break.

石塑线条

二、表面膜纸附着不好,假烫现象。

石塑线条(电梯套)表面的花色纹理是通过热转印把一层膜纸烫印到基材上。这是决定电梯套表面使用年限的最根本的一个决定性因素。经常出现的问题就是掉膜,膜纸附着不好,很短时间内就脱落。造成这个成品故障主要有以下几点。

1、烫印师傅技术不过关。烫印膜纸是按照基材的形状,运用不同的唐银轮,把膜纸烫在石塑线条的表面,对烫印师傅磨轮,和经验方面要求很高,技术好,经验丰富的师傅烫印出来的线条一般不会出现假烫事故,

2、基材和膜纸之间的面料质量不过关或者根本不用面料。面料是一层质量很好的塑料颗粒,它的使用主要是增加膜纸的附着和使用年限,价格较贵,利益驱使下,有些不良商家用质量不好的面料或者干脆不用,导致假烫。表面成品开始看不出什么,但是在安装和使用过程中,膜纸很容易脱落或者使用年限很短。

3、膜纸质量的区别。这是原材料层面的问题,便宜膜纸不好烫,烫不牢,从而影响石塑线条成品的表面使用年限。

4、物理原因,模具部分区域糊料,造成面料中断,该区域烫印不牢。一般表面眼睛看不出来,但是安装过程中,擦拭或者磕碰,很容易掉膜。
