Under what circumstances is pvc poisonous

In the use of some ordinary items, people tend to only care about the condition of the item. It is only in the material of the item, which is often ignored by everyone, but in fact, doing this is also a kind of influence in disguise. , The material is equivalent to the foundation of the article. If the foundation is not well investigated, the subsequent operations can’t be said, then under what circumstances is pvc poisonous? What material is pvc?

Under what circumstances is pvc poisonous

PVC material itself is not toxic. If it is a monomer or degradation product that is not fully polymerized, it will have a certain degree of toxicity. Under high temperature and ultraviolet radiation, polyvinyl chloride will degrade. At this time, if people use it again, it will degrade. The finished products of PVC plastic can easily cause damage to the internal system of the human body, causing hepatic angiosarcoma.

1. Due to the insufficiency of the characteristics of the PVC material itself, people have to add a large amount of additives to stabilize the PVC plastic. In fact, pure PVC plastic is not toxic. Under the comprehensive action of various additives, toxic substances are produced by chemical reactions, which means that these additives can turn PVC plastic into a softer chemical additive. After using a large amount of PVC plastic, it will affect the internal kidney, liver, etc. of the human body. The impact is very big.

2. PVC plastics include urea-formaldehyde and melamine-formaldehyde. If we process and manufacture PVC plastics, their reaction is not complete, which will result in a large amount of free formaldehyde remaining in the PVC plastic, and this formaldehyde is another kind of formaldehyde. Cells are toxic to the original pulp. If a bowl made of PVC material is used to hold hot food, the human body will easily cause some cells to deteriorate after being eaten, which is not good for human health. There is also chlorine in PVC plastic. When we burn it , It will produce a toxic substance that pollutes the environment
