Ultrafine powder processing industry has a promising future

Modern industrial production and manufacturing technology has profound changes have taken place, these changes have a common characteristic, that is the product original base material application, new type of ultrafine powder materials became the most upstream of manufacturing industry and raw materials. Almost all manufacturing and manufacturing sectors in heavy and light industries have been sapped. In today's world, the production, processing and application level of ultrafine powder has become a national standard of scientific and technological development. Attention and grasp the characteristics of this trend, with a unique perspective to find the hozhou industrial economic development direction of the focus.

Modern industrial manufacturing; For example, in paper making, it is generally necessary to add 10%-20% ultrafine powder to paper sizing. In high-grade copper sheet paper, the addition amount of kaolin (or calcium carbonate) ultrafine powder is as high as 40%. Also like plastic products, the amount of modified ultrafine powder can be up to 30%-50% depending on the product requirements. Some PVC products have been added up to 70%. Superfine powder in rubber, plastic, electronics, cables, paints, coatings, abrasives, pharmaceuticals, cosmetics, ceramics, building materials, food processing heavily and household electrical appliances, such as American flour production rules for a certain amount of talcum powder to add. More than 6000 mesh ultrafine powder is added to the plastic products (e.g., TV cabinet), not only can improve the look of the product size, finish, color, feel physical indicators, such as can also improve product strength, flexibility, toughness and aging resistance.

Also like the car chassis paint made from the superfine powder of calcium carbonate above ten thousand eyes, the car chassis can have stronger anti-erosion ability than steel plate. The addition of kaolin ultrafine powder in the cable skin can increase the insulation strength of the cable by 5-10 times. The cosmetics made with the superfine powder of more than ten thousand eyes make you can only see the natural beauty and hardly notice the trace of cosmetics. In addition in oil catalytic cracking, molecular sieve, detergent, cleaning agent, product modification, metal smelting, chemical synthesis, aerospace, high temperature superconductivity, machinery manufacturing, etc. Especially in high-tech areas has the extremely widespread application. It is the basic material of these industrial sectors and hence the demand is particularly high.

According to incomplete statistics, in 1998 China's paper industry demand for ultrafine powder is about 500000 tons, about 200000 tons of paint, paint, detergent, 800000 tons of petrochemical 400000 tons, for the most widely use the biggest plastic, cable, rubber, ceramics, refractory materials, building materials and so on to have relatively accurate data source. Our country "15" planning draft non-metallic mineral development during the tenth five-year plan for heavy calcium carbonate powder 2.5 million tons, talcum powder, 400-400 tons, kaolin, 1000-12 million tons of production.

The U.S. consumed more than 40 million tons of ultrafine powder annually in 2000. It can be seen that the demand for ultra-fine powder is large. According to last year, China's demand for ultrafine calcium carbonate powder has more than 4 million tons, detergent (mainly for washing powder) on the amount of powder more than 800000 tons, with raw materials of powder, the production of automotive friction materials is also demand of 400000 tons. So the trend is very fast.

Ultrafine powder is mainly produced by metal and non - metallic ores and organic compounds. The ultrafine powder produced from metal or metal ore is iron powder, aluminum powder, magnesium powder, titanium iron powder, manganese iron powder, copper powder, lead powder, zinc powder, zinc oxide powder, molybdenum powder, tungsten powder and so on. With compound processing of non-metallic mineral ultrafine powder with kaolin powder, titanium dioxide, talcum powder, feldspar powder, calcite powder, quartz powder, coarse whiting powder, light calcium powder, jade-like stone powder, mica powder, barite powder, graphite powder, gypsum powder, peng bentonite powder, etc., with organic processed has all kinds of food, agricultural products, medicinal materials, other animals and plants processed into powder.

All these ultrafine powders are important raw materials in modern industry, most of which can be used directly in the production of industrial products. The use of ultrafine powder materials can be multiplied by modification. After modification of ultrafine powder is not only a kind of filling material, it as a product of a kind of important components, can enhance and improve the product such as strength, elasticity, wear resistance, high temperature resistance, ageing resistance, anti radiation, and so on performance. And can greatly reduce the production cost of products.
