When modified granulation manufacturers produce drawn products, the drawn products often have rough surfaces and poor finish after being drawn, which often fail to meet customer product quality requirements, resulting in defective products and increased production costs.
Baozhuan New Material’s customers have solved the problems of surface finish and roughness of drawn products by using our silicone powder. The correct solution to the rough surface of nylon products
This customer is engaged in the production of nylon products spun from nylon and silicon carbide powder. Before finding our silicone powder products, the nylon products he produced often had rough surfaces and poor finish. Therefore, the nylon product customer consulted our company’s technical engineers through the recommendation of a friend (who is also a customer of our company’s silicone powder products).
After understanding the problem, a technical engineer from Baozhuan New Material, matched our silicone powder BZSP001 product to solve the problem. The reason why the surface of nylon filament products is rough and not smooth enough is mainly because when customers process silicon carbide powder and nylon modification, the raw materials are not fluid enough, resulting in insufficient screw mixing. When the raw materials cannot be completely mixed, it will directly affect the uneven distribution of nylon filament products, resulting in problems on the product surface. The correct solution to the rough surface of nylon filament products is that after PVC recycled materials are granulated, the products made by downstream customers using PVC particles will not have enough gloss. The reason for this is often that PVC recycled material manufacturers add calcium powder when granulating recycled materials to reduce production costs. Calcium powder will cause matting, so it often results in the gloss not meeting customer requirements when PVC products are injected after granulation.
How to improve the surface gloss of products granulated with PVC recycled materials?
PVC recycling granulation manufacturers have tried to add many plastic additives to improve the surface gloss of PVC injection molding products, but they have not achieved good results. PVC recycling granulation manufacturers are determined to try again and want to use silicone series additives to solve the problem. After comparing online, PVC recycling granulation manufacturers decided to choose Baozhuan New Material Plastic’s silicone powder for testing.
How to improve the surface gloss of PVC recycling granulation products?
After the PVC recycling granulation manufacturer docked with the technical engineer and communicated with him about the processing technology, Baozhuan New Material’s technical engineer recommended that the PVC recycling granulation manufacturer add a proportion of 0.8%. So the PVC recycling granulation manufacturer conducted a test. After the test, the PVC recycling granulation manufacturer found that the gloss of the particles on the surface of the PVC was significantly improved, meeting the gloss requirements. The main solution principle: The PVC recycling itself contains calcium powder, but our silicone powder contains silicone oil. As long as the coating is good, the gloss will be improved. Another point is that the internal and external lubrication effect is improved, the screw mixing strength is better, and the discharge effect is uniform, which can also improve the gloss of the product.
