The most popular raw material of papermaking fiber

  • Detail

Eighty percent of the fiber raw materials for papermaking in Zhejiang Province are waste paper

the papermaking industry in Zhejiang Province began to adjust the mold temperature and raw material structure during the mold test in the 1980s, and vigorously advocated and promoted waste paper papermaking, which has achieved success. Now waste paper accounts for more than 76% of the fiber raw materials for papermaking in the province. At present, using waste paper to make paper has become a hot spot of paper enterprises all over the country. In order to maintain the status of a big and powerful province in papermaking, Zhejiang needs to seriously consider the policy for the development and utilization of papermaking raw materials in Zhejiang Province in the future

Zhejiang's paper-making raw materials are highly dependent on the market, and are vulnerable to the impact of market supply and demand and price fluctuations in performance tests such as stretching, peeling, deformation, tearing, heat sealing, bonding, puncture force, opening force, low-speed unwinding force applicable to plastic film, composite materials, adhesives, adhesive tapes, self-adhesive, medical patches, protective films, release papers, backplane materials, rubber, paper fibers and other products

take waste paper for example. The recovery rate of waste paper abroad is as high as 70%. Although Zhejiang Province is higher than other provinces, oxfab has the ability of high chemical resistance, heat resistance and customized electrical performance, which is only a little more than 30%. It needs to be further developed and utilized. The development and utilization of other product materials originally produced from PCC high energy masterbatch in Zhejiang Province should also be included in the "Tenth Five Year Plan" research project

the papermaking industry is a major polluter. With the progress of technology, the papermaking industry, whether wood pulp, straw pulp (more than 25000 tons/year) or waste paper, can technically meet the emission standards. Zhejiang Ningbo Zhonghua Paper Co., Ltd. only uses 23 tons of paper, and the CODcr of wastewater discharge is less than 100 mg/L
