CaCO3 Filler Masterbatch Production And Application Market

Aug 14, 2017

CaCO3 Filler Masterbatch Production and Application Market
     CaCO3 Filler Masterbatch has been in the market since the early 1980s, because of its low price, excellent product performance, can improve some of the physical properties of plastic products. {TodayHot} alternative synthetic resin, and the production process is simple, less investment, with significant economic and social benefits. Thus, CaCO3 Filler Masterbatch is the fastest growing new industry in the plastics industry in recent years and has become one of the key additions to the plastics processing industry and the main addition of plastic products.
    Production Status of CaCO3 Filler Masterbatch
    CaCO3 Filler Masterbatch was originally used to fill the CaCO3 Filler Masterbatch, which was developed by taking advantage of the byproducts produced by polypropylene cracking - random polypropylene. With the rapid development of the plastics industry, CaCO3 Filler Masterbatch is not only an added material, can reduce the production cost of plastic products, but also has to improve the physical properties of plastic products, such as reducing the gap shrinkage, improve the appearance and feel and other characteristics Get the market recognition, has become an indispensable raw materials in some plastic products. With the improvement of advanced technology and production technology, CaCO3 Filler Masterbatch varieties, performance, use are to adapt to the needs of the market and constantly changing.
    (1) the main production equipment. CaCO3 Filler Masterbatch production equipment, the first high-speed mixer mixed, two-roll open-type plastic molding machine or closed-type molding machine, after mixing tablet, flat cutting machine granulation. As the production process is only applicable to the production of random polypropylene as a carrier of CaCO3 Filler Masterbatch, mixing effect is poor, impurity content, uneven dispersion, low yield, quality is unstable, and gradually parallel to the twin-screw extrusion Granulation units and other production equipment replaced.
    According to incomplete statistics, at present, the domestic production CaCO3 Filler Masterbatch production line of more than a thousand, 80% of the manufacturers using high-speed mixer and parallel twin-screw extrusion granulation granulation. {HotTag} twin screw extruder with screw diameter of 60mm-80mm for the largest screw diameter of 110mm, aspect ratio is generally (L / D) 28: 1-40: 1. (Including double-stage single-screw extruder granulator unit), single-screw extruder granulation unit equipment is low in cost and relatively low production cost, but because of the process of mixing The effect is far less than twin screw extrusion granulation unit, so, in product quality and production yield is limited
    (2) the main raw and auxiliary materials. CaCO3 Filler Masterbatch main materials are olefin resin, non-metallic mineral powder as filler (CaCO3 dosage accounted for more than 80%, talc powder about 10%, kaolin, silica fume, etc. about 5% -85), the main surface active agent aluminum An acid ester coupling agent, a titanate coupling agent, a silane coupling agent, and the like. Plasticizers and other additives, mainly stearic acid, PE wax, paraffin, white oil and so on. (A) The choice of carrier resin is generally the same as or close to the resin selected for the plastic product, and the melt flow rate is slightly larger than that of the product. In addition to PP, PE and other resins, PS, EVA, ABS and other resins as the production of dedicated CaCO3 Filler Masterbatch carrier, at present, has been developed applications, application areas and the use of is expanding. (B) Non-metallic mineral resources are abundant, inexpensive and easily processed, and have become the main material of CaCO3 Filler Masterbatch. CaCO3 Filler Masterbatch used in the most heavy calcium carbonate, generally require more than 95%, water content <0.3%. Te, Si02 content of the larger impact on the product, Fe content is high, the impact of product whiteness, Si02 on the processing equipment to wear. CaC03 whiteness is good, easy processing, low price, particle size was granular, is filled with CaCO3 Filler Masterbatch application of the largest and most widely used inorganic materials, the largest amount is 400 mesh -1250 mesh, now gradually to the refinement, function Development. Modified CaCO3 Filler Masterbatch is a new modified material developed on the basis of CaCO3 Filler Masterbatch. With talc, wollastonite, kaolin and other large amount of application, modified CaCO3 Filler Masterbatch can significantly improve the physical properties of plastic products to improve the defects of certain materials, such as car bumper, instrument decoration pieces. The use of PP + talc, can improve its impact strength, reduce shrinkage.
    Enhanced CaCO3 Filler Masterbatch mainly to inorganic materials (mica, glass fiber, etc.) to improve the mechanical properties of products, and some in the processing to add special properties of resin or additives, such as adding antioxidants, heat stabilizers, flame retardants Additives, as well as the addition of POE, EVA and other modified materials.
