Can paper-plastic packaging bags be recycled?
Paper-plastic packaging bag is a new type of packaging bag with high strength, anti-aging, high temperature resistance, moisture-proof, breathable. Widely used in commodity bags for packaging food, fresh and frozen food, starch, casein, feed, building materials, chemicals, mineral products and other industries. So how do we deal with it after use? SUNY GROUP has always carried out environmental protection to the end. After continuous research, continuous improvement, and continuous trial production, the paper-plastic separator is suitable for the separation and recycling of various paper-plastic composites. This equipment integrates wet decomposition, crushing, kneading, separation, cleaning, and dehydration to carry out paper-plastic composites. separation of things.
The paper-plastic separation equipment developed and manufactured by SUNY GROUP can efficiently separate coated paper, composite woven bags, kraft paper bags, cement bags, fruit bags, paper mill materials, beer labels, high-pressure double-coated paper, instant noodle boxes, milk boxes, trademarks Paper and other paper and plastic waste, and support on-site test machine experiments.
Paper and plastic packaging recycling machine
Working principle:
After preliminary crushing, the raw material enters the feeding port of the equipment through the conveyor belt, and is sprayed and moistened. The pulp fiber further absorbs water and swells. The high-speed rotating rotor drives the raw material to roll and rub in the inner cavity of the equipment. The pulp is separated from the plastic surface and passes through the orifice plate with water. In the discharge system, the pulp can be dehydrated through the pulp thickening recovery machine and the pulp press machine; the plastic washed by spraying is driven by the rotor and discharged from the equipment through the discharge port.
Precautions:
1. High-strength eddy current and strong pulping effect are generated during work, which promotes full swelling, loosening and dispersion of various paper fibers into single fibers, avoiding excessive cutting, damage, and affecting fiber length and strength. Effectively avoid the breaking of light impurities such as plastic sheets and back film, so as to facilitate screening and removal.
2. Under medium-concentration conditions (4-12%), the fibers rub against each other, extrude, and knead strongly, so that various diaphragms and fibers are separated. At the same time, the pulp suspension has low viscosity and strong fluidity, and the fibers absorb water and moisten. , become soft and plastic, which is conducive to improving the quality of paper. Operation and maintenance Close the slag discharge valve, fill the tank with clean water to 1/3 height, and check whether there is any leakage in the slurry system pipeline. Start the motor, check whether the direction of rotation of the impeller is correct, and pay attention to whether the equipment is running normally. When the equipment is operating normally, it can be fed. Feeding is based on the principle of uniformity, and the concentration is properly controlled. The raw materials containing coarse impurities and metal impurities should be cleaned up to avoid damage to the equipment. Bearings and lubricating oil circuits should be checked frequently, and oil should be added at least once a month.
Paper-plastic separation equipment has a scientific and reasonable process. It does not need to add any chemical raw materials for separation and recovery, and does not need heating. It saves time and effort, and the separation is thorough. Paper and plastic are all separated and recycled for reuse. Water recycling, no waste water, no waste, no pollution to the environment. It is a new type of environmental protection separation and sorting equipment. The purity of plastic can reach about 99%, the purity of paper fleece can reach about 99.5%, and the recovery rate of raw materials can reach more than 99.9%. It has truly realized "turning waste into treasure, limited resources, infinite circulation".
SUNY GROUP has developed through many years of research and development experience and the cooperation of cooperative manufacturers. According to the characteristics of paper-plastic composite materials and paper-plastic mixtures, it adopts the method of water mixing and spindle sieve plate friction separation. This paper-plastic separator has been unanimously certified by many cooperative manufacturers and customers that the product's production capacity and effect have reached a high level in the industry, and it has become a very important node equipment in the paper-plastic regeneration granulation and pulp recycling links.
