PVC flame retardant, Shandong Advanced Technology (certified), PVC flame retardant provided by Aetna New Material Technology Co., Ltd., Shandong. Shandong Antai New Material Technology Co., Ltd. (www.antaitech.com) is specialized in the "fireproof material" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: the Wu Hu. Two-stage extruder consists of two parts Weifang retardant PVC manufacturers, with the first order for high-speed twin-screw mixer, second-order low-speed single-screw extruder PVC flame retardant suppliers, both vertically orthogonal arrangement, constitute a double order of composite unit; complementary co-rotating twin-screw combined with the advantages of a single screw. Twin-screw conveyor mandatory, efficient plastics mixing and shear dispersion, inorganic head back pressure reflux, avoiding high shear overheating; high-pressure single-screw extruder, but low speed shear, also avoid overheating contradiction. Particularly suitable for processing PVC and other heat-sensitive materials. Twin screw processing temperature of 150 ~ 185 ℃, single screw temperature 130 ~ 165 ℃. Using air grinding grain fervent way retardant PVC manufacturer, pellets after cyclone shaker into the hopper. PVC cable quality problem cause analysis here mainly with extrusion granulation processes to be analyzed and explained. Some simple routine questions, such as pellet blocking (cooling is not sufficient), die, or only a portion of the material inconsistency where the material (die uneven heating or heating impervious, material flow and poor causes), etc., there is not as Description of focus. Shandong Antai New Material Technology Co., welcomed the new and old customers to buy.
