Description

Technical Field

[0001] The utility model belongs to the technical field of melt filtering filter elements, and in particular relates to a high-precision pressure split flow filtering melt filter element. Background Art

[0002] In the processes of chemical fiber spinning, injection molding, and bottle blowing, in order to improve product quality, reduce defective products, improve production efficiency, and reduce costs, filtering polymers is an essential step. Due to the presence of unreacted monomers, solid impurities mixed in the raw materials, polymer gels, etc. during the polymerization reaction, and the small diameter of the filaments during high-speed spinning, and the need for high-ratio stretching; solid impurities, gels, and other foreign matter during injection molding and bottle blowing affect the light transmittance of the product. Therefore, improving the purity of the polymer is one of the key factors to ensure the normal progress of the next process and the quality of the finished product. When the existing melt filter is filtering, the flow rate of the melt is slow. If the melt filtration time is too long, it will gradually cool down and solidify, causing the melt to be blocked in the filter element, affecting the filtration of the melt.
