Synthesis of cosmetic plastic containers to promote the development of the industry and made great contributions to improve people's life level. At the beginning of the development of plastic industry, chemical stability of the composite material is one of the important research content of people are very concerned about and. For decades, its stability has been a good solution. Dramatic is, today its stability has become obstacles to the further development of an important reason. 'Agricultural film' is a good example. Because is hard to biodegradable, can be used only once, simple treatment method is to set it. Not only waste resource, but also causes pollution of the atmosphere. Industry for cosmetic plastic containers of recycling and utilization has three concepts, namely direct use, conversion and burning or biological decomposition. Conversion as the name implies is used for other purposes. At the same time contains both chemical and physical methods. Physical conversion, similar to the direct use, the difference is for producing factories to their use of the latter, the former for other factory use. Process is broken Granulation - Extrusion molding ( Stretch) Or injection, if necessary, add other items. Chemical methods can be divided into two kinds: one kind of method is the use of polymer chemistry, polymer into small molecule compounds, or simple. Such as polyester can use hydrolysis, alcohol solution or ammonia solution method into a single or small molecular compounds. Hydrolysis reaction is the reverse reaction of polyester synthetic reaction, can be made into terephthalic acid and ethylene glycol ( Polyester synthetic raw material monomer) ; Methanol methyl alcohol solution can get terephthalic acid and ethylene glycol; Ethylene glycol alcoholysis products for terephthalic acid double hydroxyl ethyl ester; Propylene oligomer ChunChun solution, for the synthesis of unsaturated polyester ( Paint or ink) And with alkyd resin. Another method is to use plastic flammability, burned to produce heat energy to generate electricity. The two methods have advantages and disadvantages, chemical decomposition method, the resource utilization is higher, but the process is complex, high cost, thus affecting the recycling of plastic products. Incineration of waste gas, such as PVC ( Polyvinyl chloride (PVC) film) Containing chlorine gas produced by the body after burning, it is a component of acid rain, many other plastics produced by incomplete combustion exhaust gas, cosmetic plastic containers of great harm to the environment and human health, so this method has a tendency to be eliminated. 512.
