Asbestos powder is powdery non metallic materials containing asbestos fiber,

in a waterproof material, asphalt material, heat insulation materials and other fields have more extensive application

Asbestos (English: Asbestos and Asbestos), is a natural fibrous siliceous minerals to collectively, is a kind of silicate minerals

are widely used in building materials fire prevention board fiber, also is the only natural mineral fiber, it has good tensile strength

and good thermal insulation and anticorrosive, not easy combustion, it is widely used.

Asbestos is a lot of more phyletic, according to its mineral composition and chemical composition is different,

can be divided into two categories, serpentine asbestos and amphibole asbestos.Serpentine asbestos chrysotile and said,

it is a kind of the asbestos production most, has good spinning performance.Can be divided into the blue amphibole asbestos asbestos,

tremolite and actinolite asbestos etc., less than serpentine asbestos.

Q: Why PVC watts relative to asbestos tile, color tile good?: PVC tile is mainly made of polyvinyl chloride resin (PVC), supplemented by UV anti UV agent and other chemical raw materials. It is made up of advanced technology by scientific proportion. PVC watts, also known as plastic steel tile, is a color steel tile replacement products. Multi layer co extrusion composite technology is adopted to coat the surface of the product with anti-aging layer, which improves the weather resistance and color persistence, and the bottom layer increases the wear resistance layer. With good fire resistance, corrosion resistance, weather resistance, asbestos free ingredients, bright colors, environmental protection and health. It is widely used in the roof and wall of large span portal structure workshop. It not only meets the anticorrosion requirement of light steel structure workshop, but also saves steel and reduces cost.There are advantages to it:1, in terms of price, it is more affordable and practical;2, fire - oxygen index OI = 32, which is flame retardant materials;3, corrosion resistance - chemical resistance, more than 3 times longer than the zinc plate life;4, strong toughness - impact resistance, tensile, not brittle;5, weather resistance - because of the material added UV anti UV agent, so the product can really play anti ultraviolet radiation, life long;6, low noise - when raining noise is extremely low, than the metal roof panel noise reduction of more than 30db;7, portability - easy to install and transport, save time and effort;8, beauty - bright color, bright and colorful;9, environmental protection - asbestos free ingredients, no carcinogenic and other substances released.

Q: What substances are CFC, HFC or asbestos, and what is the harm to humans?: By asbestos fiber bundles, and fiber bundles by a long and thin can separate fiber asbestos. With high flame resistance, electrical insulation and thermal insulation, fire prevention is important insulation and insulation materials.Asbestos itself is not toxic, it's the greatest harm from the fiber, which is a very small, almost invisible to the naked eye fiber, when these tiny fibers are inhaled, will be attached and deposition in the lungs, causing lung disease, asbestos has been the International Cancer Research Center for certain carcinogens.

Q: The density of asbestos can not be found on the Internet. All of them are asbestos sheets, asbestos nets, asbestos ropes, asbestos free asbestos, and those asbestos materials are not studied well. What about those? I'll see if I can get back to the density of asbestos on the Internet Wipe!: Asbestos is a natural fibrous mineral, not asbestos asbestos density of 2.55, after mechanical dispersion, asbestos soft, fluffy fiber, the volume increases.

Q: When is the last bus to asbestos in Chengdu Shiyang bus station?: Now a lot of cars, take the high speed, more than 3 hours can go, and the last 1 to asbestos is 18:00

Q: Where is the difference between glass fiber and asbestos?How about the grade of glass fiber? How to detect? What are the levels?How is asbestos rated? What are the levels?: Asbestos is a natural fibrous siliceous minerals generally referred to, is a widely applied in building fire prevention board of silicate mineral fiber, natural mineral fiber is unique, it has good tensile strength and good heat resistance and corrosion resistance, not easy to burn, so it is widely used. There are many kinds of asbestos, the most common three are chrysotile asbestos (Bai Shimian), iron asbestos (brown asbestos) and bluestone (Lan Shimian), of which chrysotile asbestos is the most abundant and the most widely used.Glass fiber is a kind of inorganic nonmetallic material with excellent properties. English name is: glass fiber. It is prepared by high temperature melting, wire drawing, winding and weaving process with glass balls or waste glass as. All kinds of products formed finally, glass fiber monofilament diameter from a few microns to twenty micron, the equivalent of a hair 1/20-1/5, each bundle of fibers are hundreds or even thousands of root root filaments, usually as a reinforcing material of complex materials, electrical insulating materials and insulation materials, circuit board, etc. and widely used in various fields of the national economy.Glass fiber has (no) roving and twisted to form spinning frames of different specifications and uses. There are two kinds of alkali (R2O < 0.8%, code E) and medium alkali (R2O12.0 + 0.47%, code C). Mainly used as glass steel paste, lamination, winding, injection enhancement material and the insulation, composite and fireproof glass products production molding.

Q: What else is the use of asbestos nets besides chemistry?: And metal composite material for high temperature protection, it can avoid the rocket plume and high-speed flight due to damage caused by high temperature. Asbestos and glass fiber, nylon fiber woven composite material is also used for rocket and missile industry.

Q: Physical and chemical properties of asbestos: Different kinds of asbestos are different in physical, mechanical and chemical properties. Asbestos fiber length is generally 3~50 millimeters, also has longer. China has found the longest asbestos fiber, 2.18 meters, the longest in the world. Serpentine asbestos with good alkali resistance, almost no alkali corrosion, but acid resistance is poor, very weak organic acids can be asbestos in the Magnesium Oxide precipitation, so that the strength of asbestos fibers decline.Amphibole asbestos belongs to the monoclinic structure. The color is generally deep, the proportion is bigger, has the high acid resistance, the alkali resistance and the chemical stability, the corrosion resistance is also good. Especially the filter performance of blue asbestos is better, and it has the important characteristics of preventing chemical poison and purifying the air polluted by radioactive material. Distinguish between serpentine asbestos and amphibole asbestos is put into a mortar asbestos, chrysotile felt mess, fiber is not easy to separate, amphibole asbestos after grinding easily into many small fibers. Iron free asbestos is white, iron containing asbestos in different shades of blue.

Q: Asbestos products are prohibited in those countries: Most European Union countries, Japan, Australia and other countries have also issued regulations prohibiting or restricting the production and use of asbestos products.

Q: Asbestos Market Overview: The consumption of asbestos in China is the largest of the consumption of cement products, accounting for about 70% to 80% of the total consumption, followed by 8% to 12% of friction materials, about 6% to 8% of sealing materials, and about 9% of textile products and other uses.China's exports of asbestos are low, with exports of 3472 tons in 2003, mainly exported to North Korea (1234 tons), Thailand (1539 tons), Malaysia (513 tons), Japan (48 tons), amounting to $1 million 556 thousand and 200.China used to import some of the long fiber asbestos, in order to make up for the shortage of domestic long fiber asbestos. After 1991, the influx of Russian asbestos, imports rose sharply, only in 2003, in addition to import 1366 tons of asbestos fiber, the amount of $about 960000 over the same period, generally also imported 142111 tons of asbestos, amounting to $24 million 310 thousand.

Q: How to produce fumed silica from asbestos tailings": Hello! Produce fumed silica from asbestos tailings, but so far the domestic technology is not yet mature, Yunnan Dai application in the production of gas serpentine fumed silica patent, but did not realize industrialization.
