Method for fully recycling and reproducing waste drip irrigation belts and waste greenhouse films

Abstract

The invention relates to a waste drip irrigation tape and waste greenhouse film total recovery and reproduction method, and relates to the technical field of waste drip irrigation tape and waste greenhouse film resource recovery and reutilization, and the method comprises the following steps: waste material cleaning: putting waste drip irrigation tapes and waste greenhouse films into a cleaning pool for full cleaning; waste material drying, wherein the cleaned waste drip irrigation tape and the cleaned waste greenhouse film are dried; the waste materials are cut up, wherein the dried waste drip irrigation belts and the dried waste greenhouse films are cut up; mixing the raw materials: fully mixing the chopped waste materials with the new plastic material and the dyeing master batch; granulation: adding the mixed raw materials into an extruder for extrusion granulation; and film forming: performing blow molding and film forming on the raw material particles to finish reproduction of the waste materials. The waste drip irrigation tape and the waste greenhouse film can be utilized to the maximum extent, and the produced product is good in performance and good in application effect.

Description

technical field [0001] The invention relates to the technical field of resource recovery and reuse of waste drip irrigation belts and waste greenhouse films, in particular to a method for full recovery and reproduction of waste drip irrigation belts and waste greenhouse films. Background technique [0002] Greenhouse film refers to a special plastic film used for facility agricultural production and construction. Its light transmittance, heat preservation, tensile and aging resistance are better than ordinary agricultural film. It is of great significance to the growth of greenhouse crops, increasing production and increasing income. There are mainly four kinds of greenhouse films commonly used in my country: the first is polyvinyl chloride film; the second is polyethylene film; the third is ethylene-vinyl acetate copolymer film; the fourth is dimming agricultural film. membrane. [0003] The drip irrigation belt uses plastic pipes to send water through the orifice or dripp...

AI Technical Summary

Problems solved by technology

[0004] After the greenhouse film and the drip irrigation tape are used for a long time, the wind and the sun will cause aging and produce a large amount of waste plastics. Since the plastic is a high molecular polymer with stable chemical properties, it is difficult to degrade in the natural environment, causing "white pollution" and severe environmental pollution

[0005] Some existing recycling measures can recycle greenhouse film and drip irrigation tape, but the treatment process is not perfect, there is no mature process system, and the treatment effect is uneven, which affects the effect of recycling and does not maximize the realization of resource recycling.
