Recently, Zhongke Refining & Chemical's 350,000-ton/year polypropylene plant successfully produced new grades of high-melting index fiber materials, filling the gap in Sinopec’s production of high-melting index fiber materials by degradation method in South China.
High-melt index fiber material is a high-quality raw material for high-speed non-woven fabrics for medical masks. It has a good market prospect and requires extremely high production process operations. Zhongke Refining & Chemical Co., Ltd. meticulously compiles trial production plans and grade switching instruction sheets, organizes technical backbones to carry out technical research, and confirms plan details. When converting production, the production technicians kept a close eye on the adding speed and amount of solid additives during the whole process, and the equipment engineers always paid attention to the operation status of the extrusion granulation unit and adjusted various indicators in time to ensure the successful trial production of the high melting index fiber material.
