This will further stimulate the molybdenum powder usage grows in the paint, paint consumption. In addition, molybdenum powder has good weather resistance, have the important characteristics of abrasion resistant, low electrolyte content, PH stabilizing effect, can improve the corrosion resistance and paint rheology, etc. basic group processing is mainly for the production of fine printing and writing paper, to newsprint and some important papers, although produce in the Powder coating oven acid-based environment, but also can be used molybdenum powder. The main used of molybdenum powder filler is plasticized PVC (cable, floor leather, etc. According to reports, the coarse whiting is nowadays widely used in polyvinyl chloride, polyethylene, polypropylene and various unsaturated resin, of which PVC products are the earliest and largest market of molybdenum powder.
The Worlds papermaking process from acidic shift in the alkaline was culminated in mid-1990s, calculated in paper production capacity, in 1997 the United States alkaline and neutral papermaking process accounted for 80% of total papermaking production capacity. Western Europe accounted for 65%. From the information that metal powder exportersupplied, we know that currently the paper coating grade molybdenum powder produced by China cannot meet the production demands, the large gap needs to import to supply. This shift gives molybdenum powder a huge market.
Since the world paper industry from the beginning of the 1980s was succeeded by from an acidic process to alkaline process change, make the use of filler has occurred a revolutionary change.mhcmp. Molybdenum powder is the important filler in the paint production, fineness and particle distribution determines the transparency of the paint. In addition, adding coarse whiting can improve the stability of plastics.
Molybdenum powder is a very important filler material, especially in Europe, by weight, it accounts for 60% of the mineral filler and reinforcing agent market. Whats more, use molybdenum powder in the paint can reduce the amount of titanium dioxide, it is advantageous considered economically.) and polyethylene. To 2000, the United States in addition to a small amount of special paper products, 95% of the production capacity is alkaline or neutral, Europe also up to 80%. For example, in soft polyethylene wire, polyvinyl chloride, polyvinyl chloride tiles, calcium plastic material, accounts for 20%-50%, in polyethylene, polypropylene packaging material accounts for 10%-30%, in the automotive parts, ceiling accounts for 20%-60%.
Production of paint is another vital purpose of molybdenum powder. Molybdenum powder in water-based coating series is also very important, it can improve the performance of quick-drying, in the road crossed has an important significance. Molybdenum powder instead of wood pulp and other pigments can improve the papers brightness, no permeability, porosity, bulk density, etc.Coarse whiting as a filler added to the plastic, not only plays the role of compatibilize, increment, reduce costs, make the fabric evenly, but also improve the processing performance, wear resistance, tensile strength, impact strength, bending strength, breaking elongation and thermal properties of products, etc
