Waste plastics recycling and utilization, has become a worldwide topic, the recycling of plastic products, not only can protect the environment, save energy, but also has the very good economy.
the manufacturer is in manufacturing process, inevitably produce some bad product, these bad goods piled up there, and how we should deal with?
small make up today as tell your factory is how to deal with these abandoned plastic hose, we generally has three methods: direct use, conversion and burning or biological decomposition.
the direct use of plastic products processing is mainly physical process, is the agent or add color masterbatch, basically is also physical mixing processes. Heat the plastic slice or aggregate after melting, injection plastic products, injection blow molding product or film extrusion blow molding or extrusion casting pieces of stretch film. Due to the change in the process of the material are all is a physical change, its chemical structure remains unchanged, it provides convenience for the application of the leftover material. So in producing plastic products factory, in the production of leftover material generally is broken, after extrusion granulation or melting extrusion granulation, put into production line continue to use again. Manufacturers will often choose to use this method.
conversion as the name implies is used for other purposes. At the same time contains both chemical and physical methods. Chemical methods can be divided into two kinds: the first method is the use of polymer chemistry, polymer into small molecule compounds, or simple. 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, capital is high, 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 combustion, is a component of acid rain, also many plastics produced by incomplete combustion exhaust gas, does great harm to the environment and human health, so this method has a tendency to be eliminated. 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.
biodegradation due to plastic products is not easy to aging, hard to microbial decomposition, causing the so-called white pollution. Rather than passive treatment, from the source to find a way to, is also because of so, plastic industry attaches great importance to the research and development of biodegradable plastics. At present, from two aspects of performance and biodegradability were satisfying varieties almost none. To truly realize industrialization, there is still a long way to go.
