wood plastic composite production process

wood plastic composite production process, including at several points 1) Stabilizer: composite lead salt stabilizer: the advantage of good thermal stability, weather features, the disadvantage is not toxic and environmentally friendly, poor dispersion during processing, it is difficult to maintain products, excellent physical properties. Manufacturers in the production will be different according to the different uses of the production levels of lead stabilizers (PVC rigid products, pipes, profiles, sheet; flexible cable products, hoses, etc.) wood-plastic composite production of lead content of lead salt stabilizer most well not less than 30%. In order to process the composite lead salt stabilizer need to add some lubricant (stearic acid, paraffin wax, PE wax oxidation Pe wax, etc.) for the production of composite lattice panels foam is best plus oxidized PE wax help adjust the recipe and do not affect the product quality (with good lubrication). The amount of good and bad, according to the size of the old and new processing methods and equipment, screw, stabilizer, and generally add 4-5% .. Not be used for transparent products, with sulfide pollution, can not be mixed with organic tin. Organotin stabilizer: the advantage of good thermal stability can be used for transparent products, add less, low toxicity, the disadvantage is the high price, because it is somewhat inconvenient to transport and use of liquid. Lubricity general, and metal stearate and used to addition to the synergistic effect and can reduce the amount of organic tin, and reduce costs. Ca-Zn stabilizer: is a non-toxic and environmentally friendly new heat stabilizers have two kinds of liquid and powder, the disadvantage is to add a large amount of poor thermal stability, good lubrication. Most of the domestic production of wood-plastic composite lead salt stabilizer Yin Jiage cheap. But a little departure from environmentally friendly materials as wood environmental purposes, and there is a certain influence on the adjustment formula and product quality and stability. Stabilizer not better it also has an optimum amount, less thermal stability is not enough, more impact plastics and physical properties of the product. 2) foaming agent: outside flooring materials basically using Sai Luka design which will help improve the expansion ratio and hollow products, production, so I recommend using the CCR-10 hair foaming agent, thermal deformation, weather resistance, environmental protection and other demanding sheet, profiles, tubes and the development of a modified blowing agent, hair volume slightly less than AC, but decompose completely, to improve the rigidity of products Vicat has helped. Slow decomposition when the extrudate exits the die surface cools rapidly, the cell structure contributes to the formation of dense surface for 赛卢卡 and Crust foam. 3) Lubricant: select and match their usage, both inside and outside the former balance and ensure adequate lubrication of the amount of lubricant in the late varieties of lubricant is to ensure normal production of key wood. Many different types of lubricants such as stearic acid, paraffin wax, PE wax, oxidized PE wax, stearate, monoglyceride, PETS, EBS, etc., some of which are within the lubricant, outside slip agents, some of which are pre-lubricants some late lubricant, but they are in different processing temperatures can be interchangeable. Different machines have different amount of lubricant, more than a single screw and twin screw amount of slip inside and outside focus is different, new and old, and the size of the amount of equipment is not the same, simple slip inside and outside of the amount of product shapes are different, different stabilizers the amount of lubricant is not the same (some stabilizers lubrication, some do not). How much influence the stability of the lubricant production and continuous production cycle, the apparent product, foam and mechanical index products. 4) foam regulator: The use of outdoor wood flooring density is not the same size is generally about 0.7 to 0.8, so the general requirements can be achieved with the 530, its molecular weight 5,000,000 or so, as with higher molecular weight modifier is foamed helpful but will reduce the rigidity of the product. General dosage is 6-8. 5) the use of coupling agents help to improve fibers and inorganic filler to improve the compatibility of the product and reduce mechanical index of water absorption article, I propose to use DL-88 is used in an amount of 1.5% of the total fiber and filler, which affordable rates and performance comparable with a silane coupling agent. And is a solid powder weighing and add convenience. 6) toughening: in wood products in Canada, I recommend without elastomer toughening or less, because the elastic properties of products related to appreciate the impact. To add to add Our PA-48, it does not reduce the product's Vicat,If you want to understand the situation more wood products, please click here to have a surprise for you!wpc floor for sale
