What do you usually do with waste paper? How is it then turned into new paper?

To the 1980s the recovery rate of waste paper has reached about 25%, a few manufacturers can also produce deinking pulp. Into the 1990s, some large and medium-sized paper enterprises have introduced from abroad, including the production line, including deinking equipment and technology, and waste paper deinking agent and waste paper deinking equipment for targeted improvements and innovations, so that China's waste paper utilization and processing technology and equipment assembly level to the overall development. Some larger cardboard production enterprises, the use of imported waste paper and the introduction of deinking equipment and technology to produce high-grade products. Such as Shanghai Hongwen Paper, Fujian Qingzhou Paper Factory, Liaoyang Industrial Paperboard Factory, Anhui Wuhu Oriental Board Paper Factory, etc., the use of imported waste corrugated cardboard boxes, the use of hot dispersion method or cold sieve method of treatment of recycled pulp as the core, bottom pulp, in the introduction of the production line or the original introduction of the paper machine, the production of kraft cartonboard and paper with copying paper and other varieties of paper bag paper. Not only is the quality and grade high, but also the old imported corrugated paper containing adhesives and impurities that affect production and are prone to cause paper diseases can be effectively dealt with, ensuring the normal operation of the production line. Enterprises represented by Guangzhou Paper Company Limited, China Paper Company Limited and Fujian South Paper Company Limited have respectively introduced deinking production lines or main equipment from abroad, and adopted the comprehensive flotation-washing method to treat old newspapers and old magazine paper. Guangzhou Paper Mill and Fujian South Paper Co., Ltd. seem to be recycled pulp with copied newsprint. Ltd. Ningbo China Paper Co., Ltd. is the use of waste paper recycled pulp as the core pulp and bottom pulp, the production of coated white paperboard, have achieved better results. Some domestic research units and production units to cooperate in research and development of deinking technology and equipment, the use of existing conditions for innovation, the production of small quantities of waste paper recycled pulp has been successful. Manufacturers in Xuchang, Jiaozuo, Suixian, Xinxiang and other places in Henan Province have utilized imported AOCC and other waste paper to copy high-strength corrugated paper and boxboard with remarkable results. Small and medium-sized enterprises, such as Fuzhou Second Paper Mill and Nanning Xinyang Paper Mill, utilize domestic equipment and technology to process old newspapers and old cardboards, and produce toilet paper and low-grade white cardboard. Henan Province, Hebi paper mill will be the original equipment slightly modified, the use of old newspapers to produce recycled newsprint. Xuchang, Yanshi paper street, the use of waste paper production of toilet paper. Xinmi City, some paper mills using old domestic cartons to produce cardboard, kraft paper and other low-grade products have achieved good results. Domestic equipment manufacturers and chemical production, research units, through cooperative research, in the performance of equipment, chemical quality has also achieved good results. For example, Hangzhou Light Industry Research Institute developed a small waste paper treatment process and waste paper deinking system. Liaoyang Paper Machinery Factory and Fujian Light Industry Machinery Factory research waste paper treatment equipment has formed a supporting series, successfully put into production. Shandong's some paper machinery factory also produced different types of deinking equipment, has been purchased by manufacturers to use. There are Fujian Paper Research Institute, Hangzhou Chemical Research Institute, Tianjin University of Science and Technology and other units of research and development of various types of deinking agent has also been recognized by users. The industry on how to rationalize the enterprise waste paper recycling and utilization of a few suggestions: 1. Purchase of waste paper raw materials should be strictly controlled. Especially imported waste paper, in the current supply channels more cases, more careful action. Enterprises must operate waste paper suppliers to carry out a comprehensive investigation to understand the source of supply, economic strength, reputation, etc., so as to avoid being deceived. 2. enterprises with strong financial and technical strength, in the purchase of foreign old corrugated cardboard boxes, old magazine paper and old newsprint at the same time, but also the introduction of foreign countries, including the existing production line, including deinking technology and equipment, the production of high-quality regenerative pulp, up-grade products. For the existing grass pulp alkali recovery of enterprises can also use imported waste paper recycled pulp to add grass pulp, commercial wood pulp, proportionally copied high-grade cultural paper. 3. has been shut down or pollution control hopeless paper mills, can invest a small amount of money on the original equipment to slightly improve the transformation, the use of domestic waste paper production of low-grade toilet paper, corrugated paper or recycled newsprint and other products; can also use domestic and imported waste paper pulp with copying of high-grade products, it will be possible to get out of the predicament. Enterprises in the purchase of waste paper, should be combined with their own equipment, technical strength, production varieties, such as categorized use. Can use imported corrugated cardboard, AOCC waste paper production of high-grade boxboard, high grade corrugated paper and paper bag paper, or as the production of white paperboard core pulp and bottom pulp material; use of waste newspaper with about 30% of the old magazine paper, after flotation - washing integrated deinking, the production of newsprint or as the white paperboard core pulp and bottom liner pulp; the use of imported miscellaneous office paper, such as photocopying paper, computer printout, etc., to choose a new deinking method, and the use of waste paper, such as copy paper, computer printout. Selection of new deinking methods, in the improvement of paper machine or the introduction of the production line, the production of high-grade cultural printing paper. Purchased domestic waste paper can produce low-grade boxboard and toilet paper. At the same time in the use of waste paper recycled paper, should pay attention to the use of chemical additives to make up for the lack of physical strength and other indicators of paper products.
