0.2 Micron Pp Spun Filter Element

Regarding the production process of melt-blown filter element, the process is divided into several steps, before melt-blown molding, we must first prepare the corresponding raw materials, and all the prerequisites for production must be ready to avoid some basic errors in the production process. The main raw material of polypropylene melt blown filter element is polypropylene particles, which is the basic structural raw material of pp spun filter element, the others are secondary, mainly polypropylene particles, and the others are some auxiliary production process materials, such as stabilizers, enhancers, and color masterbatches. Before being put into production, these basic materials should be screened, cleaned and dried, so as to ensure the high purity and good quality of the spun depth filter element produced. After the material is ready, it is necessary to begin the molding of the pp melt blown filter element. The molding principle of the melt-blow filter element is very simple,…
