Calcined aluminum oxide has the advantage of quite small coefficient of expansion, excellent hydrophilicity, great toughness and great great strength. Calcined Aluminum Oxide Abrasive Cloth usually used for polishing stainless steel, hard metal, titanium alloy, casting metal and welding lines.
Abrasive Cloth is the cloth with grinding compound. According to the different grinding compound, the abrasive cloth can divided into four kinds: Aluminum Oxide Abrasive Cloth, Silicon Carbide Abrasive Cloth, Zirconium Oxide Abrasive Cloth and calcined aluminum oxide abrasive cloth and so on. According to the hardness, it also can be divided into flexible abrasive cloth,middle flexible abrasive cloth and hard abrasive cloth. Some of them can do waterproof or oil-proof. The shape of the abrasive cloth is roll, belt and sheet. The abrasive cloth is generally used for wood grinding and metal grinding. It can available in vary grits.
After 30 years` development, abrasive cloth grinding has become a complete and self-contained system of new processing technology. Because of its high processing efficiency, wide application range, strong adaptability, low cost, safe and convenient operation, it is well received by customers. In foreign countries, Abrasive Belt grinding technology has made great progress. It can be applianced for more and more processing object . It can process almost all engineering materials, from the general daily life appliance to application of large aerospace equipment.

How to fertilize fertilizer in winter
How to make fertiliser fertilizer in winter should do the following: choose a place for fertilizer. It is necessary to choose a region that is close to the faecal source and convenient for transportation. The manure pile is planned to be occupied. The pile of manure is round and the height is about 1.5-1.8 meters. The piled agricultural fertilizer is broken and mixed well. In winter, it is necessary to increase the amount of hot fertilizer such as livestock manure, so that fermentation can be faster and the quality of fertilizer can be improved. Try to minimize the amount of water and loam to increase the temperature and speed up the fermentation. At the bottom of the manure pile, a layer of cattle, horse manure or weeds should be laid first, and then various mixed fertilizers should be piled up. If it is cold in winter, if the dung heap is too small, it will be easy to be frozen and not easy to ferment; increase the drying pile to make the heat dissipate slowly and ferment. It is also possible to adopt the method of sealing mud insulation, and to cover some heat preservation such as firewood straw around the manure pile. It is also very advantageous for the farmer to use some methods to cover the manure pile.
