Most plastic material is polyethylene or polyvinyl chloride, will generate CO after incomplete combustion, in addition, the material burning chlorine generates HCl, toxic. In addition plastics also add a lot of additives, these biomass burning also releases toxic substances organic substances class range of plastic types, such organic substances include phenol, cresol, benzene, toluene drunk, Mo Virginia, formaldehyde, urea, acetylene. to plant fiber as a basic component of plastic The main products are made of cotton but wood flour, pulp, paper and cloth manufacturing many types of plastic which can play a very important role in the burning characteristics: very different combustion characteristics of various plastics, depending on the shape of the product ( solid section, films, plates, foam, molded shapes, synthetic granules and powders) and chemical composition. does not burn or remove the source of fire stopped after burning products, including phenol containing asbestos, a number of polyvinyl chloride, nylon, and some fluorocarbons. There is also a class of products easy to burn, but burn more slowly, after clearing fire may stop may not stop burning. These plastic water content of formaldehyde (urea or phenol) and some ethylene derivatives. milli unhindered burning, and after clearing the source of fire to continue burning products, including polystyrene, propylene, some of cellulose acetate and polyethylene plastic cups combustion products: burning plastic cups will produce flammable gases, heat ., flames and smoke after leaving the fire will continue to burn, the flame status: yellow-based (upper yellow, the lower blue); plastic state of change: melting dripping strongly stimulate smell of formaldehyde, these substances also contains some fatal toxic gases. Most plastic cups are associated with the combustion smoke. In general, urethane or flame in the flame avid, smoke will emerge, it will make within a few seconds around visibility deteriorated. It will produce a deadly gas when burned, but also irritating gas while in Shanxi TT exhaust gas purifying combustion exhaust gas treatment plastic lights can handle hazardous gases produced when burning plastic, with a small, easy management, good effect, low operating costs and having both sterilization and other characteristics used for the majority of environmental companies.
