Recycling and processing of waste woven bags

the waste woven bags are recycled and processed into ordinary protective particles for making 2. Spring testing machines. A lot of pollution will be generated in the process. At present, most manufacturers process them into particles and then use them for injection molding products. Now, through scientific research, it has a new space for use

experts organized by the science and Technology Department of Hubei Province appraised the process and technology of Wuhan Institute of Chemical Technology for manufacturing high-grade polypropylene pipes with waste woven bags. Experts believe that the research results with independent intellectual property rights are in line with the idea of circular economy, can save a large amount of crude oil, and have positive significance in promoting the construction of various kinds of engineering pipelines in China

China has nearly 3million tons of waste woven bags every year, which is one of the main components of white pollution that is difficult to degrade naturally. The production of a ton of polypropylene pipes Requires 25 tons of crude oil, which is a pressure on China, which is lack of oil. Yuanjun, associate professor of Wuhan Institute of chemical technology, and others have cooperated with Honghu science and Technology Co., Ltd. since 2002, they have begun to study the use of waste woven bags to manufacture polypropylene pipes. Through toughening, strengthening and modifying the recycled materials of waste woven bags, they prepared a special material for polypropylene pipes, which has stable performance, good repeatability and excellent process performance; They adopt the patented technology and special mold independently developed, and use their polypropylene pipe special materials to manufacture a series of drainage pipes with a molded diameter of 1.2m. The process is unique and advanced

it is reported that only about 1/5 of fresh materials need to be added to produce polypropylene pipes with this process and technology, and the performance is equivalent to that of all pipes produced with fresh materials, and the price is reduced by about 30%. At present, three enterprises in Shanghai, Hubei and other places have used this process and technology to cover basic research and utilization research, forming a production capacity with an annual output of 50000 tons and an annual output of 500 million yuan under the favorable policies and the promotion of the government. It is estimated that if half of the waste woven bags can be regenerated into polypropylene pipes every year, the output value can reach nearly 20billion yuan, and 37million tons of crude oil can be saved
