PVC注塑产品的表面光泽问题
PVC回料造粒后,下游客户使用PVC粒子后,做出的产品会出现光泽度不够的现象。而造成这样的原因,往往是PVC回料厂家在回料造粒时会添加钙粉,用来降低生产成,而钙粉会导致消光作用,所以往往会导致造粒后进行PVC产品注塑时光泽度达不到客户要求。PVC回料造粒厂家尝试了添加许多塑料助剂来改善PVC注塑产品的表面光泽问题,但是都没有达到很好的效果,PVC回料造粒厂家于是抱着再次尝试的心态,想使用硅酮系列的助剂来解决,PVC回料造粒厂家在网上对比后,决定选择XX塑料的硅酮粉来进行试样。
After PVC granulation, the products produced by downstream customers will not have enough gloss after using PVC particles. The reason for this is often that the PVC recycling factory will add calcium powder in the recycling granulation to reduce the production, and calcium powder will lead to extinction, so it often leads to the glossiness of PVC products after granulation injection can not meet customer requirements. PVC recycling granulator tried to add many plastic additives to improve the surface gloss of PVC injection products, but they did not achieve good results. So the PVC recycling granulator tried again and wanted to use silicone series additives to solve the problem. After comparing on the Internet, the PVC recycling granulator decided to choose the silicone powder of XX plastic for the sample.
PVC回料造粒厂家在与公司技术工程师对接后,与其沟通加工工艺后,技术工程师推荐PVC回料造粒厂家添加比例0.8%,于是PVC回料造粒厂家进行了试样,试样后PVC回料造粒厂家发现PVC表层的粒子光泽度明显提高,达到了光泽度要求。
After docking with the company's technical engineers and communicating with them about the diaosurw.37ix.com.cnzhagungp.37ix.com.cnzhibanx.37ix.com.cnwalengzhi.37ix.com.cn  technology, the technical engineer recommended that the proportion of PVC recycling granulator be 0.8%. So the PVC recycling granulator carried out the sample. After the sample, the PVC recycling xianweisu.37ix.com.cnprocessinggranulator found that the glossiness of the particles on the surface of PVC was obviously improved, which met the glossiness requirement.wushui.37ix.com.cn
主要解决原理:本身PVC的回料里含有钙粉但是我司的硅酮粉里含有硅油这块只要包覆的好,光泽度是会提高的,还有一点就是内外润滑效果提高,螺杆混炼强度更好了出料效果也就均匀了,同时能提高产品光泽度的功效的。
Principle of Solution: PVC material contains calcium powder, but our silicone powder contains silicone oil. As long as the coating is good, the gloss will be improved. Another point is that the internal and external lubrication effect will be improved, the screw mixing strength will be better and the effect of discharging will be uniform, and the gloss of products can be improved.
