The thermal decomposition of waste plastics plastics products

Thermal decomposition technology, the basic principle is that the waste plastic polymer resin for a more thorough Plains macromolecular chain decomposition, bring it back to low molar mass state, thus obtained using high-value products. Different varieties packaging company of plastic thermal decomposition mechanism and thermal decomposition products varies. PE, PP thermal decomposition of the main form in a random chain scission, almost no thermal decomposition products of the corresponding monomers, accompanied by thermal decomposition and random chain scission depolymerization reaction, some thermal decomposition products of styrene monomer , pvc plastic package first removal packaging design of the thermal decomposition of hydrogen chloride, then scission at higher temperatures, the formation of hydrocarbons.
Thermal decomposition of waste plastic pyrolysis process can be divided into low and catalytic decomposition, the former generally at 600 a high temperature of 900 , the latter even less than 450 300 the lower temperature, clear plastic box decomposition products of both different. Waste plastics pyrolysis reactor used are: tower, furnace type, trough, tube furnaces, fluidized plastic trays bed and extrusion machines. This technique is plastic case more thorough waste plastics recycling technology. Pyrolysis of the feedstock oil recovery methods, the need to carry out the reaction at a high temperature, a large investment in equipment, plastic box recovery costs are high, and the reaction process of coking phenomenon, thus plastic packaging limiting its application. The low-temperature catalytic decomposition due to the relatively low temperature reaction, so the research more active, and has made some progress.
Gulf states plastics consumption will grow 22% in

Gulf Petrochemicals and Chemicals Association (GPCA) predicts annual plastics consumption in the GCC countries in 2015 will grow by 22% clamshell packaging from the current 3.3 million tons to 5.5 million tons.
Gulf Petrochemicals and Chemicals Association Secretary Sadoun said that the increase in consumption is due to plastic plastic compound production expansion.
Although plastic accounts for only GCC petrochemical products 20%, but in value has reached 70%
