BaSO4 Filler Masterbatch in the selection of time there will be some need to pay attention to the problem
BaSO4 Filler Masterbatch in the choice of time there will be some need to pay attention to the problem, these problems, usually we will ignore the problem, for these problems, BaSO4 Filler Masterbatch manufacturers for the sake of everyone, to give you some knowledge, I hope you can Draw this knowledge.
BaSO4 Filler Masterbatch is also commonly used as a functional dyeing with the masterbatch, the same choice and other masterbatch is not the same, specifically reflected in what place? Here to give you a detailed description of these issues.
Different BaSO4 Filler Masterbatch, the choice of paint, the performance is different, the following were introduced under the BaSO4 Filler Masterbatch how to choose the pigment:
Heat-resistant masterbatch The choice of pigments, the most basic requirements of the polypropylene fiber production process can withstand the temperature, to maintain its stability. Temperature temperature is generally required for the 270 ~ 280 ℃ above.
Dispersible color masterbatch pigment should be excellent in dispersibility, and in the masterbatch to be dispersed evenly, and the use of dispersants will not reduce the quality of polypropylene fiber or else can not produce good quality liquid stained liquid, the operation is not stable , It is easy to break or produce abnormal fibers when drawing fibers.
Brightness Polypropylene liquid coloring has a variety of uses, which are used for bedspreads and knitted fabrics, require bright colors. Because organic pigments are bright and bright, and easy to color, so that the use of organic pigments for the use of the above.
Light resistance In the light of the role of some pigments have photosensitive effect, so that coloring fiber fade and fragile, and the light resistance of the pigment is basically related to its chemical structure, so in the production of masterbatch should pay full attention to the light resistance, Of the pigment need to be used, you can consider adding UV absorbers.
The pigment used in the stable masterbatch has excellent stability to the colored polypropylene fiber, meaning that the pigmented fiber polymer does not react with the fiber after prolonged exposure to heat, light or high temperature to form a new chemical The performance of the polymer is low.
Buy high-quality BaSO4 Filler Masterbatch, to my company, my company's product quality excellent, cost-effective, loved by the majority of users.
BaSO4 Filler Masterbatch is the main component of filler, mainly used for polyolefin (polyethylene and polypropylene) processing molding, also known as polyolefin BaSO4 Filler Masterbatch. Polyolefin BaSO4 Filler Masterbatch raw and auxiliary materials selection: Polyolefin BaSO4 Filler Masterbatch is composed of resin, filler and various additives composed of three parts, which accounted for the main component of the filler, up to 90%. Polyolefin BaSO4 Filler Masterbatch is mainly used for the production of polyolefin plastic such as polyethylene and polypropylene. Such as: polyethylene hollow blow molding products, polyethylene injection products and polyethylene film, polypropylene woven bags, woven cloth and packing belt, and so on. General choice of olefin BaSO4 Filler Masterbatch raw and auxiliary materials, to take into account its good performance, low cost.
(1) filler polyolefin BaSO4 Filler Masterbatch used in the filler is mainly heavy calcium carbonate, followed by talc, kaolin, wollastonite powder and other inorganic fillers. It is an important technical indicator for any inorganic filler, particle size and particle size distribution. Usually the smaller the particle size, the narrower the distribution, the better the filling effect. In addition, the filling effect is also good or bad with the dispersion, the smaller the smaller the difficulty of dispersion, the higher the price. Purity is another important technical indicators of inorganic filler, the less impurity content, the higher the purity the better. General use of heavy calcium carbonate selection, its content as high as possible, the general requirements of more than 94%. To ensure that other indicators meet the requirements, the price is low, in order to help reduce the cost of masterbatch.
