PVC profile formula and its performance characteristics
在我们的日常生活中，PVC型材随处可见，PVC型材大家听的少，感觉陌生，但是一说塑料，估计大家并不怎么陌生了吧。可以说是，我们的生活离不开塑料。正因为塑料的出现，它给我们的生活带来了许多便利，比如：我们平时购物时，用塑料袋装我们购买的物品;我们平时喝的饮料，装饮料的容器材质也是塑……今天，小编给大家介绍一下PVC型材配方和其性能特点。
In our daily lives, PVC profiles can be seen everywhere. PVC profiles are rarely heard and feel unfamiliar, but when it comes to plastics, it is estimated that everyone is not very unfamiliar. It can be said that our lives cannot do without plastic. Because of the emergence of plastic, it has brought many conveniences to our lives. For example, when we shop, we use plastic bags to hold the items we buy; The drinks we usually drink are also made of plastic containers... Today, I will introduce the formula and performance characteristics of PVC profiles to you.
PVC树脂，它是一种具有强烈的分子作用力的聚合物。一般是白色粉状物质，没有毒性，没有任何气味，不能在水中溶解。但是它在极高温度下，会有刺鼻性气味生成，这种气体是氯化氢，这种气体有毒，极易溶于水，会被人体吸收，导致中毒。
PVC resin is a polymer with strong molecular forces. Generally, it is a white powdery substance with no toxicity, no odor, and cannot be dissolved in water. But at extremely high temperatures, it can produce a pungent odor, which is hydrogen chloride. This gas is toxic, easily soluble in water, and can be absorbed by the human body, leading to poisoning.
PVC型材的种类分为两种，一种是软性PVC型材，另一种是硬性PVC型材。在我们的家庭中，门窗的边框就是PVC型材，还有水管的管道，这些都是硬性的PVC型材。我们平时用的行李箱其材质有的就是PVC型材，在国家网电局用于输电的电缆也是PVC型材，这些都是软性的PVC型材。
There are two types of PVC profiles, one is soft PVC profiles, and the other is hard PVC profiles. In our family, the frames of doors and windows are made of PVC profiles, as well as the pipes for water pipes. These are all hard PVC profiles. The luggage we usually use is made of PVC profiles, and the cables used for power transmission in the State Grid Administration are also made of flexible PVC profiles.
随着科学技术的日益进步，PVC型材的性能越来越强大。如今的PVC型材的性能种类及其繁多，有的能抵抗强酸强碱的腐蚀，有的耐高温……在一些PVC型材中，有的性能强大的甚至可以代替铝合金或者其他金属材料。
With the increasing progress of science and technology, the performance of PVC profiles is becoming increasingly powerful. Nowadays, there are a wide variety of performance types of PVC profiles, some of which can resist strong acid and alkali corrosion, while others can withstand high temperatures... In some PVC profiles, some of which have strong performance and can even replace aluminum alloys or other metal materials.
