Opportunities for the food and packaging machinery industry (Part 2)

enterprises represented by Guangzhou Paper Co., Ltd., Zhonghua key Paper Co., Ltd. in combination with the problems and technical research in the current utilization of oilfield chemicals and Fujian Nanzhi Co., Ltd. introduced deinking production lines or main equipment from abroad, and used flotation washing comprehensive method to treat old newspapers and magazine paper. Guangzhou paper mill and Fujian Nanping Paper Co., Ltd. make paper with recycled pulp. Ningbo Zhonghua Paper Co., Ltd. used recycled waste paper pulp as core pulp and bottom pulp to produce coated white paperboard, and achieved good results

some domestic research and production units have cooperated to research and develop deinking technology and equipment. After innovation by using the existing conditions of the enterprise, the production of small batch of recycled pulp of waste paper has been successful. Manufacturers in Xuchang, Jiaozuo, suixian, Xinxiang and other places in Henan Province use imported AOCC and other waste paper to make high-strength corrugated paper and carton board with remarkable results

Fuzhou second paper is widely used in small and medium-sized enterprises such as Arsenal and Nanning Xinyang paper mill. Domestic equipment and technology are used to treat old newspapers and cardboard and produce toilet paper and low-grade white cardboard. Hebi paper mill in Henan Province slightly reformed its original equipment to produce recycled paper from old newspapers. The papermaking street in Xuchang and Yanshi uses waste paper to produce toilet paper. Some paper mills in Xinmi have achieved good results in the production of medium and low-grade products such as carton board and kraft tissue paper from domestic old cartons

domestic equipment manufacturers and chemical production and research units have also achieved good results in equipment performance and chemical quality through cooperation. For example, Hangzhou Light Industry Research Institute has developed a small waste paper treatment process and waste paper deinking system. The waste paper treatment equipment studied by Liaoyang paper machinery factory and Fujian Light Industry Machinery Factory has formed a supporting series and has been successfully put into production. Some paper machinery factories in Shandong also produce different types of deinking equipment, which have been purchased and used by manufacturers. In addition, various deinking agents developed by Fujian paper institute, Hangzhou Institute of chemical industry, Tianjin University of science and technology and other units have also been recognized by users

insiders put forward several suggestions on how to reasonably recycle and utilize waste paper:

1. Strictly control the purchase of waste paper raw materials. In particular, imported waste paper, in the current situation of more supply channels and unpredictable business means, we should be more cautious. The enterprise must conduct a comprehensive investigation on the waste paper suppliers, understand the real situation, supply and marketing sources and history, economic strength, reputation, etc. of the business unit, select reliable supply partners, and purchase goods by agreement, so as to avoid being cheated and causing undue economic losses

2. For enterprises with considerable scale, strong financial strength and strong technical force, when purchasing foreign old corrugated boxes, old magazine paper and old paper, they can also introduce foreign existing deinking technology and equipment, including production lines, to produce high-quality recycled pulp, replace wood pulp fibers, and produce high-grade and multi variety products. This is not only conducive to environmental governance, but also can significantly increase benefits. For enterprises that have already recovered straw pulp alkali, they can also use imported waste paper recycled pulp to add straw pulp and commercial wood pulp, and prepare high-grade cultural paper in proportion, which can not only reduce pollution load, save pollution control costs, but also reduce production costs

3. For paper mills that have been shut down or have no hope of pollution control and are about to be shut down, a small amount of money can be invested to slightly improve and transform the original equipment. Domestic waste paper can be used to produce low-grade toilet paper, ordinary corrugated paper or recycled paper, and domestic and imported waste pulp can also be used to make medium and high-grade products. It is possible to get out of the difficulties of raw material shortage and difficult pollution control and turn to a virtuous cycle

4. When purchasing waste paper, enterprises should classify and use it in combination with their own equipment conditions, technical strength and production varieties. The imported corrugated 2 can be used as a strong data processing function for cartons and AOCC waste paper to produce high-grade cardboard, high-strength corrugated paper and paper bag paper, or as the core pulp and bottom pulp material for the production of white cardboard; Using waste newspapers plus about 30% old magazine paper, after flotation washing comprehensive deinking, paper can be produced or used as the core pulp and bottom lining pulp of white paperboard; Using imported office waste paper, such as copy paper, computer printing paper, etc., and using new deinking methods, we can produce high-grade cultural printing paper on improved paper machines or imported production lines. Medium and low grade paperboard and toilet paper can be produced from purchased domestic waste paper. At the same time, when using waste paper to recycle paper, we should pay attention to the use of chemical additives to make up for the lack of physical strength and other indicators of paper products

5. Domestic machinery manufacturers, chemical manufacturers and papermaking enterprises, scientific research institutes of linear error and other relevant units jointly develop advanced deinking equipment and deinking agents, enhancers and other chemicals, constantly improve the technical level of equipment for recycling paper from waste paper and the adaptability of paper varieties, and promote the rapid development of waste paper utilization
