The practical application of metallic stearates and PVC stabilizers
Metal stearates and PVC stabilizers are relatively common lubricants, metal salts of stearic acid and stearate in the melt between the wall surface and the metal thin film is formed, thereby providing lubrication role, but the stearic acid, metal salts of stearic acid salts are typically alkaline,WSD plastic processing aid,PVC processi it is to be appropriately selected depending on the type of plastic, the polyethylene wax is a polyolefin.WSD plastic processing aid,PVC processi lactose dryer Features : metal stearates fast drying, greatly increasing the surface area of the atomized liquid, PVC stabilizer in the hot gas stream instantaneously 95% -98% of water evaporation, drying time is only a few seconds to complete bell, especially suitable for drying heat-sensitive materials. Metallic stearate products with good uniformity, mobility and solubility,WSD plastic processing aid,PVC processi high purity and good quality. Production process is simplified, easy to operate controls. PVC stabilizers and metal stearate to 40-60% moisture content (up to 90% special materials) can be a liquid product was dried to a powder after drying without crushing metal stearates and screening, reducing production process, improve product purity. PVC stabilizers product particle size, bulk density, water,WSD plastic processing aid,PVC processi within a certain range can be adjusted by changing the operating conditions, easy to control and manage. Working principle: PVC stabilizer heated air through the filter and into the top of the dryer hot air distributor,WSD plastic processing aid,PVC processi and then into the drying chamber was evenly spiral. Feed speed centrifugal atomizer at the top of the tower through the liquid, metal stearates rotation into a very fine spray mist droplets, PVC stabilizers in contact with the hot air flow in a very short drying time is finished, PVC continuous output stabilizer finished bottom of the drying tower and cyclones, exhaust gas from the turbine emptying.

WSD plastic processing plastic products introduced in the role
WSD plastic processing in plastic products proportional share of less than 8%, but its role in the improvement and progress of plastics processing and application performance of it is unquestioned, now an array of plastic products almost invariably reflects the plastics additives function and role. Them with resin, processing machinery, Glycrin monostearate together constitute the three basic elements calcium stearate of the world's plastics industry.
WSD plastic processing categories and numerous different functions. Depending on the function and role, often including stabilizing additives, processing aids and functional system gives agents the three systems. With the increased development of the plastic industry, plastic resin structure, advancement and application of technical advances in molding product performance requirements, which greatly promoted the expansion of categories of plastic additives consumption and production progress.
WSD plastic processing can be divided into "synthetic additives" and "processing aids" two systems. Synthetic additives is defined by the monomers involved in the polymeric resin during various auxiliary chemicals, such as polymerization, initiator, molecular weight modifier, the terminating agent, emulsifier,PVC heat stabilizer for window dispersing agentand antifouling agent. They are intended to improve the conditions of the polymerization, to adjust the size and distribution of molecular weight, is closely related to the polymerization process, the polymer resin and is generally not into the plastic article, the return on such additives customary in the discussion of the synthesis resin, and statistical category is not listed as plastic additives. The basic concept in the frame of modern plastics additives given in terms of processing aids.
Is well known, WSD plastic processing molding process with the article consists essentially of, mastication, shaping processes to complete. In this process, resin, additives, processing equipment (including mold) is an integral part of the basic elements. In contrast, the additive in plastics formulations insignificant,magnesium hydroxide flame retardant but its role in the improvement and advancement of product processing and application performance on important. We can say that after the polymer resin structure determination, selection and application of additives products is the key to the success of the decision.
