  • Detail

The smoke that ignites the wallpaper is just carbon particles produced by the full combustion of PVC in the air; The smell comes from the trace amount of HCl produced during combustion, which is often referred to as hydrochloric acid

you often encounter some merchants who sell wallpaper and ask the shopping guide to make a wallpaper burning demonstration. They prepare two kinds of wallpapers in advance. One is the so-called non environmental wallpapers, which are often mentioned in the market " pvc" Wallpaper, the other is "e; Pure paper "e; Wallpaper. In the demonstration of combustion " Pure paper "e; When wallpaper, white smoke is released, and the burning smell is slight, but in the burning belt " pvc" When wallpaper, it emits black smoke and smells the smell of burnt plastic. Consumers are credulous that those who smoke white must be environmentally friendly, and the other must be inferior products. They mistakenly think that PVC (polyvinyl chloride) is toxic. In fact, it is not. This practice is nothing more than a conversion of concepts, just like burning chemical fiber cloth selling cotton proves to be harmful

the truth is: the so-called thick smoke is just carbon particles produced by the full combustion of PVC in the air; The smell comes from the trace amount of HCl produced during combustion, which is often referred to as hydrochloric acid. Among them, polyvinyl chloride (PVC) is a high molecular polymer, which has no toxicity by itself; Toxic ones are PVC monomers used as raw materials for PVC production. As long as the residue of vinyl chloride monomer in the polymer is controlled, that is, PVC ≤ 1.0mg per kilogram (the limit of harmful substances in wallpaper is international gb18585-2001, which is the same as the value specified in gb9681 hygienic standard for polyvinyl chloride molded products for food packaging in the food industry), there is no harm to human body

in the production process of PVC wallpaper, PVC will experience a process high temperature environment of more than 90 ℃ (120 ℃ -210 ℃) three times in the coating, printing and embossing section, and the vinyl chloride monomer remaining in PVC will basically volatilize. Polyvinyl chloride and resin (PVC) are one of the most common chemical products, and they are also one of the environmental protection (protection of natural forest resources) materials used by trees vigorously promoted by the United Nations in recent years, such as fresh-keeping film, drinking water buckets, toys, lacquer skin of LV handbags, water pipes, etc
