Abstract
The invention discloses a recovery method for waste polyethylene plastic. The main technological process comprises: heating waste polyethylene plastic to form a plastic viscous liquid, transferring the viscous liquid into a thermal-insulation steel barrel with leaks at the bottom end, extruding when the viscous liquid is hot, so as to enable waste plastic to form strips, cutting the strips into particles, and packaging to obtain a product. The waste plastic means waste polyethylene.
Description
Technical field
The present invention relates to a kind of recovery method of waste polyethylene plastic, refer in particular to waste polyethylene plastic through heated evolves be mucus, mucus is transferred in the steel drum of low end band small opening of insulation, upper end extruding makes plastics form strip to enter in cold rinse bank, bar is cut into granular must the method for product.
Background technology
The present invention causes serious environmental pollution mainly for current waste polyethylene plastic, the also method of not effectively recycling, devise the method for easy recovery and granulation, avoid because waste plastics proportion is little, reclaim and concentrated time cost of transportation too high, thus make the situation that conventional recovery method cannot be promoted.
Because the present invention utilizes waste polyethylene plastic to obtain vinyon particle through simple technique, therefore wide application and promotion prospect will be had.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of recovery method of waste polyethylene plastic, and this method is primary raw material with waste polyethylene plastic, utilizes simple method, obtains vinyon particle by simple technical process.
The technical problem to be solved in the present invention is solved by following scheme: a kind of recovery method of waste polyethylene plastic, is characterized in that: waste polyethylene plastic is heated to 270
0c-295
0c, forms plastics mucus, mucus is transferred in the insulation steel drum of bottom band small opening, and the conduction oil temperature in insulation steel drum interlayer is 280
0c-290
0c, pressurization while hot makes plastics mucus be extruded with bar, is cut into by bar granular, packaging into products after cooling.
In the recovery method of above-mentioned a kind of waste polyethylene plastic, waste polyethylene mainly refers to waste polyethylene film, waste polyethylene bottle and waste polyethylene pipe etc.
Advantage of the present invention is: 1, very low with the vinyon particle cost of this method recovery.2, be easy to because method is simple promote.3, the environmental pollution that the recovery being applied to waste polyethylene plastic will greatly alleviate waste plastic and causes.
Accompanying drawing explanation
Fig. 1 is the process chart reclaiming waste polyethylene plastic.
