WSD plastic processing aid Introduction

  Processing aid  is a substance play a supporting role, typically having filter aid, clarification, adsorption, lubrication, stripping, bleaching, peeling, extraction solvent, with a fermentation nutrient and the like. Some for food, some used in manufacturing, and so on. PVC is a very special thermoplastic resin plastic processing aid  its pure decomposition, poor mobility, low impact strength, poor weather, and therefore need to add all kinds of supplementary material in the process to improve its performance. Lubricants, heat stabilizers, impact modifiers, processing aids and the like. Depending on the processing aid molecular weight, there are different functions.
  The main role of processing aids are: 1) to accelerate the Processing aid  of PVC plastics. 2) improve the rheological properties of the thermoplastic melt. 3) improve the mechanical properties of the melt under the heat elastic state. 4) improve the appearance of the quality of the products and other integrated functions. Although the addition amount of the processing aid, but the Processing aid  performance is improved PVC is very important. According to the function of the different processing aids can be divided into flux, melt rheology modifiers, lubricants and dispersing accelerator. In fact, each type of processing aids also have more than one effect. Any functionality and application results of a processing aid should depend on its chemical composition, the polymer structure, molecular weight and type of polymer matrix.

The practical application of PVC processing aid

PVC processing aid with flame retardant, chemical resistance (resistance to highconcentrated hydrochloric acid, sulfuric acid concentration, concentration of nitric acidand the concentration of sodium hydroxide), PVC processing aid machinery has the advantages of good strength and electric insulation. Impact modifier, poor thermalstability. Impact modifier in the case of no heating stabilizer, PVC processing aid thatbegins to decompose, the faster decomposition. PVC processing aid of thermal decomposition of a release of hydrogen chloride gas, make its color from white to pale yellow, red, brown, black, impact modifier and oxygen will make the PVC photo oxidative decomposition, so that the flexible PVC last fall, crisp. PVC processing aidfrom here is not difficult to understand, why some PVC plastic over time will turn yellow, brittle. heat stabilizer for pipe Word sense disambiguation plastics processing aids discrimination hasstable physical and chemical properties, insoluble in water, ethanol, gasoline additivesprocessing aids, gas, water vapor permeability and low processing aids; calcium zinc stabilizer at room temperature for any concentration of hydrochloric acid, sulfuric acid,the PVC processing aid under chemical corrosion resistance, has a certain; for salt is quite stable, but can be dissolved in ether, ketone, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons and other organic solvents.

Application of processing aid

Processing aids can be completely self curing, but commercially available processing aids, for quality and stability, and the circulation of commodities of processing aidsmust add stabilizer, not only all the processing agent I met will add thickening agent, if you can get the solidification type strains, PVC processing aid conditions can try look,do a good job, with a processing aid and have a look what stabilizer state, you know,why should add stabilizer. The effect of stabilizer of stearic acid metal salt thickeningand stabilization of protein is additive has the functions of a kind used in manyproducts, can bring many benefits for polymer products. We can use plastic processing additives word sense disambiguation is mainly divided into threeMetallic stearate aspects:in polyolefin acid neutralizing a group of pipe heat stabilizers on polyolefin colorstability and contribute directly corrosion; lubrication / processing aids to improve thepolyolefin, PVC profile stabilizer, plastic, plastic additives, polyamide, styrene and rubber in the extrusion film, fiber, copying and pressing molding processability. PVC profile stabilizer andCalcium zinc stabilizer for plastic, rubber and thermosetting products, such as polyurethane foamand unsaturated polyester.

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.
