Due to the lack of characteristics of PVC material itself, people have to add a large number of additives to stabilize PVC plastic, in fact, pure PVC plastic is not toxic, but after a large number of additives are added by people to transform, PVC plastic is chemically reacted with toxic substances under the comprehensive action of a variety of additives, that is to say, these additives can make PVC plastic become a softer chemical additive phthalein, after using a large number of PVC plastics, the inner kidneys of the human body, The liver and so on have a very big impact.
2. PVC material itself is not toxic, if it is not a monomer that is not fully polymerized or a degradation product contains a certain toxicity, under high temperature and ultraviolet radiation, polyvinyl chloride will be degraded, at this time, if people use the degraded PVC plastic products, it is easy to cause damage to the internal system of the human body, thereby causing hepatic angiosarcoma.
3. PVC plastic includes urea-formaldehyde and paraformaldehyde, if we process and manufacture PVC plastics, their reaction is incomplete, which will lead to a large amount of free formaldehyde in PVC plastics, and this formaldehyde is a kind of cell plasma poison, if the bowl made of PVC material is used to hold hot food, it is easy to cause the deterioration of some cells after human consumption, which is not good for human health, and there is chlorine in PVC plastic, when we burn it, It produces a toxic substance that pollutes the environment.

There must be, don't use PVC for home decoration, the kitchen and bathroom area is not very large, just use more than 100 gussets to hang well, PVC will be yellow for a long time, the thickness of the gusset is best above, pay attention to it when buying, this package is installed, PVC should be installed. You also have to buy wooden sticks to fight in trouble.

Anonymous users2024-01-22It is not recommended to use PVC.
PVC is made of polyvinyl chloride resin as the main raw material, adding an appropriate amount of anti-aging agent, modifier, etc., through mixing, calendering, vacuum blister and other processes. The advantages are flame retardancy, wear resistance and chemical corrosion resistance, but the biggest disadvantage and the most fatal disadvantage is that the thermal stability is very poor, and it will emit substances that are harmful to health at high temperatures.
You can use PS material, one is that it will not release toxic substances, and the other is that PVC has the advantages that it has.
Now environmental protection is the mainstream, those PVC materials that harm the human body will be gradually eliminated, PS materials belong to environmental protection materials, of which the "Yousen" brand PS can also be guaranteed for 10 years, it is worth buying
I don't think so. There may be a small amount of gum smell, just ventilate and disperse.
Toxic, PVC is made of polyvinyl chloride resin as the main raw material, adding an appropriate amount of anti-aging agent, modifier, etc., through mixing, pressure rolling, vacuum blister and other processes. The advantages are flame retardancy, wear resistance and chemical corrosion resistance, but the biggest disadvantage is also the most fatal disadvantage is that the thermal stability is very poor, and it will emit substances that are harmful to the health of the body at high temperatures.
The release of the toxicity of PVC gusset needs to be facilitated by external conditions, such as close contact with grease. However, this toxicity does not volatilize as a gas, and of course it does not cause harm to the human body. >>>More

General building materials can be used as ceilings, and PVC boards can also be used as modeling ceilings, but the treatment of the paint surface after PVC board ceilings is not as good as gypsum board and other boards, and the cost is not low.
