Recycling technology for waste plastic woven bags

Abstract

The invention discloses a recycling technology for waste plastic woven bags. The recycling technology comprises the following steps: firstly carrying out stage treatment on raw materials, washing waste plastic woven bags using polyethylene and polypropylene as main ingredients and waste plastic woven bags using polystyrene as a main ingredient, then drying, then taking the waste plastic woven bagsusing polyethylene and polypropylene as the main ingredients as raw materials to manufacture an aromatic compound, and using the waste plastic woven bags using polystyrene as the main ingredient as raw materials to manufacture solid resin and an adhesive. According to the recycling technology, the waste plastic woven bags are effectively recycled and further utilized in different fields, so thatmore novel and wider thoughts are provided for recycling of plastic.

Description

technical field [0001] The invention belongs to the field of packaging materials, and in particular relates to a process for recycling waste plastic woven bags. Background technique [0002] In the past few decades, waste plastics have been an important part of municipal solid waste. In the early stage, the disposal methods of garbage in cities can be divided into the following types: the first is legal landfill; It is still a dominant method; but the plastic will not decompose in a short time after landfill, so it will occupy more landfill; this is easy to cause secondary pollution, and the groundwater and land will cause different degrees of pollution; the second It is the incineration method. Plastics are polymers. Using incineration to obtain heat is another method of processing plastics. For example, the combustion value of polyolefin is very high, which is 43.3MJ / kg, which is close to 44.0%MJ / kg of fuel oil. [0003] , much higher than those of coal, wood, and paper! ...
