| The use of industrial filter paper is first designed for automobiles,and is divided into air filter paper,oil filter paper and fuel filter paper according to the application.Therefore,industrial filter paper is also commonly known as "automobile three filter paper" or directly referred to as "three filter paper",among which air filter paper is based on Its filtering function is divided into two types:engine filtration and air conditioning filtration.With the development of industrial filter paper copying technology,the performance of filter paper has been greatly improved.At the same time,according to the needs of the market,many small categories have been derived.Large can be applied to mines and power plants to filter dust,while small can be used for household appliances.Purification;some industrial filter papers that impart water absorption,water resistance,flame retardancy,etc.through papermaking auxiliaries,and can also be used in the manufacture of water purification and flame retardant filter elements.As an industrial raw material,automotive industry filter paper is limited by its downstream automotive industry.It also benefits from the strong development momentum of the automotive industry.As a filter material,it also has many performance requirements such as filtration performance.Physical properties,chemical properties,etc.,various properties complement each other and restrict each other.This paper mainly analyzes and summarizes the current situation of the market and production for the filter paper of the automotive industry,based on the traditional specialty paper manufacturer Hangzhou Xinhua Paper Co.,Ltd.Through analysis and research on the production process of automotive industry filter paper,raw and auxiliary materials,production equipment and some key process control points,the factors affecting the production and quality of filter paper in the automotive industry are obtained.According to different factors and the current state of the company to give appropriate advice and improvement methods,hoping to help companies better control product quality and cost in the production process,thereby enhancing the core competitiveness of enterprises,helping enterprises to survive and development of. |
