| The paper industry has been occupying an important position in the global industry.Modern paper industry is not in the traditional sense of the "light industry",but the important basic industries of the national economy.Vigorously develop the paper industry will become a new economic growth point,the Chinese economy will have a strong pulling effect.Indonesia,Brazil and South Korea have had to start from scratch and gradually developed into a modern large-scale industry successful experience,it is worth us to draw lessons from.Fiber raw material is the basis of pulp and paper industry,and it is also one of the obstacles restricting the development of China's paper industry.Data show that in the past 40 years,the world pulp(not including the production of waste paper pulp)laid the wood pulp fiber raw material,timber accounted for 90% of the fiber raw materials,and non wood fiber raw materials accounted for only 6%.Non wood fiber raw material is mainly used in China,India and other developing countries,the development of the raw materials used in the developed countries is almost wood,about 99%".And long term non wood raw material is one of the important reasons that lead to many problems of China's pulp and paper industry.In the long run,it is necessary to realize the modernization of China's paper industry and to solve the dual pressure of the because of "environmental protection" and "international competition" and the crisis of survival,it is necessary to take to adjust the structure of raw materials mainly by wood.Therefore,the current problems faced by China's pulp and paper industry is how effectively using limited forest resources,take what process can be the resources into high quality slurry and can reduce the cost,to reduce pollution.The lack of forest resources in China,non wood fiber raw materials in the paper raw materials will be a large proportion of long-term.Therefore,it is an important subject for the development of pulp and paper industry in China to develop the non wood resources,develop the high yield pulping technology,and improve the quality of the products.In recent years,the domestic institutions of higher learning and scientific research units have carried out research on APMP pulping of wood raw material and straw material.At present,a number of domestic enterprises have introduced the APMP production line,and achieved good economic benefits,accumulated a certain production experience.Domestic paper industry competition is intense,in order to enhance the market competitiveness of enterprises,how to reduce the enterprise production cost and production process on the environment caused by pollution,reduce subsequent manufacturing costs has become a top priority and MCC Yinhe Paper Co.,Ltd.(hereinafter referred to as: Yinhe Paper)is located in the northwestern region of North China Plain,the region mainly in the cultivation of food crops,lack of large area of forest coverage,hardwood resource scarce,in order to solve the situation of tight supply of raw materials,research in APMP feedstock join a certain proportion of pine block.So the main task of this paper is to study in the actual production process of the APMP raw material structure adjusted pine is added on the original poplar wood chip based,reduce the production cost,and reduce the abrasion of the raw material of the equipment,improve service life of spare parts,and according to the actual production of chemicals for disabled or increasing,improve the drug for the corrosion of the equipment and improve the liquid of raw materials of maceration,reach better effect of pretreatment.In the actual production process of APMP,to achieve the above requirements,whether to achieve the purpose of cost savings,it is required to carry out a long-term follow-up in the actual production practice. |
