Reutilization process of industrial solid waste

Abstract

The invention discloses a reutilization process of industrial solid waste. The reutilization process comprises the steps that (1) the recycled industrial solid waste is crushed into fragments; (2) after being crushed, the industrial solid waste is divided into a material capable of being molten and a material which cannot be molten according to certain plastic melting temperature, and the materialcapable of being molten and the material which cannot be molten are mixed according to the proportion of 1:1 to obtain a pre-mixed material; (3) a mold is taken, a layer of Dacron non-woven fabric isput in the mold, heat conduction oil is contained in an inner cavity of the mold, low-pressure circulation electromagnetic heating is carried out, the mold is firstly heated to the plastic melting temperature in the step (2), the pre-mixed material is put into the mold to be pressed, and crude finished products are obtained; (4) trimming deflashing, cooling and temperature decrease are carried out, and cooling is carried out to room temperature; (5) the product quality is detected, and unqualified products are crushed again and re-machined; and (6) qualified products are packaged. According to the reutilization process, no poisonous gas is generated during machining, various special-shaped products are obtained through machining and can be used as environment-friendly novel material products to replace wooden products and plastic products, ageing resistance is high, toughness is good, waterproofness is achieved, and cyclic utilization can be achieved.

Description

technical field [0001] The invention relates to a recycling process of industrial solid waste, which belongs to the technical field of industrial waste. Background technique [0002] With the rapid development of my country's industry, factories produce a large amount of industrial waste, a large part of which cannot be recycled, causing factory waste to be discarded everywhere, and incineration will produce a large amount of toxic gas and dust, which will bring certain pollution to the environment. [0003] Industrial solid wastes that cannot be recycled and reused are generally composite materials with different properties. They cannot be sorted and re-granulated. They are usually incinerated or landfilled. Some can be bonded with chemical resin glue to form new materials. The method is not environmentally friendly, and a large amount of toxic gas will be generated during the production process, and the product cannot be recycled.
