Little Giant Enterprise

From an ordinary piece of wood pulp paper to becoming a powerful tool for caring for the engine. The automotive filter paper produced by Shijiazhuang Chentai Filter Paper Co., Ltd. accounts for 35% of the national market, and is the largest automotive filter paper manufacturer in China. In particular, the electrospinned nanofilter paper developed and produced has broken the international monopoly and filled the domestic gap. In the second batch of specialized and new small giant enterprises in the country released by the Ministry of Industry and Information Technology, Shijiazhuang Chentai Filter Paper Co., Ltd. is among them.

In the production workshop of Shijiazhuang Chentai Filter Paper Co., Ltd., the machine roared, and different types of wood pulp fibers and special fiber raw materials were put into the hydraulic pulp machine in a certain proportion, and water was added to disperse and mix, and then pulp was beaten. The pulp slurry was produced accordingly. The pulp slurry was uniformly passed through the molding net, and after vacuum dehydration and drying, it was dipped and applied to apply adhesive and dried again, which enhanced the tensile pressure resistance, airflow shock resistance, flame retardant and other strengths and special characteristics of the filter paper. After slicing, rewinding and packaging, the filter paper can be officially offline. The production process seems simple, but the formula of wood pulp and adhesive is the core secret.

There are many types of wood pulp fibers, and the processing technology and raw materials used are different. From a large category, it is divided into broad-leaved wood and coniferous wood. For example, eucalyptus is broad-leaved wood and pine is coniferous wood. The diameter, length, breathability and filtering performance of these fibers are different. In addition, there are a variety of special fibers to meet the performance of special products, so different formulas are required.
