Technique for producing recycled article by employing pouring molding of molten waste plastic

Abstract

A method for producing a recycled article involving the pouring molding of a molten waste plastic, which comprises a step of feeding two or more types of waste plastic including a material with contaminants, a printed matter, or a colored material to a melting device to melt them together, a step of pouring the molten resin into a preheated mold by its own weight to thereby mold the resin, a step of forcedly cooling the mold having the molten resin therein and the resin with cooling water, and then a step of releasing the resulting molded article. The method has accomplished the technique wherein two or more types of plastic, which may be stained, colored or printed, may have attached matters, and may be of any material, are molded by melting them and pouring the molten resin into a mold by its own weight.

Description

technical field [0001] The invention relates to the technique of melting and casting more than two kinds of waste plastics in a metal mold. In other words, the present invention relates to the use of crushed various waste plastics, which may be materials with stained appearance, colored products, printed matter and attached plastics, which are crushed and mixed, heated and melted with most of the thermoplastic resins and then casted. Methods to manufacture recycled goods technology. The present invention also proposes equipment and methods accompanying the melting and casting technology, a series of recycled product manufacturing plants and various equipment. Background technique [0002] Among all kinds of waste, unprocessed food waste is returned to nature through composting and backfilling, but waste plastic is the most difficult to dispose of among waste, even if it is backfilled, it cannot be returned to nature, and due to the high calorie temperature during incinerati...

AI Technical Summary

Problems solved by technology

[0007] However, as mentioned above, most of the waste is not new products, such as products with a defaced appearance, printed matter, and materials with foreign objects attached, and since there are disputes about how these products can be recycled at low cost, recycled products cannot be widely used

This is the current state of material recycling and makes recycling difficult

As long as this problem is not solved, the problem of backfilling, incineration and illegal dumping cannot be solved, and environmental protection is also difficult

[0008] In addition, in the traditional recycling technology, before the recycled products are completed, they have to go through the crushing company, and the agent of pellets and ingots as the intermediate industry, so the recycled products are produced at the cost of each disposal and the cost of each transportation, and because They are sold at prices several times higher than new production items, so most are hard to sell

[0009] In addition, the recycling technology for a large amount of waste plastics, regardless of whether they are defaced or undamaged, has not been established so far.
