Application:
The use of nuts
Use of Nuts The main uses of the steel wire ropes used in mines in China are: mine hoisting (stainless steel stampings stainless steel drive chain screw), endless rope winches, aerial ropeways, haulage of belt conveyors, electric shovels and return columns. The position of such steel wire ropes in the production of coal mines is extremely important. Once problems occur, they will seriously threaten the safety of coal mines and workers. The importance of wire ropes for mining can be divided into important-use steel wire ropes and general-purpose steel wire ropes according to their importance. Important use of steel wire rope refers to the main mine, auxiliary shaft lifting wire rope, belt conveyor hauling wire rope and inclined shaft wire rope winch ropeless. The general purpose steel wire ropes are in contact with steel wire ropes in the general structure of 6*19 and 6*37. These wire ropes consume a lot in coal mines, but the technical requirements are not high, and the quality is of little impact on the production of coal mines.
Properties:
Oxalic acid can be used as a reducing agent, bleach, dyeing aid, regulator, additive, etc.
1. Oxalic acid is mainly used in the production of drugs such as antibiotics and ice tablets, as well as solvents, dye reducing agents, tanning agents, etc. for refining rare metals. In addition, oxalic acid can also be used to synthesize various oxalates, oxalates, oxalamide and other products, with the largest production of diethyl oxalate, sodium oxalate and calcium oxalate. Oxalic acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, the cleaning of metals and marble, and the bleaching of textiles. Acidity regulator used to synthesize adhesives such as urea-formaldehyde Resin and MELAMINE formaldehyde resin. The pharmaceutical industry is used to manufacture oxatetromycin, aureomycin and other drugs.
2. It is mainly used as a reducing agent and bleaching agent, and a mordant in the printing and dyeing industry. It is also used to refine rare metals and synthesize various oxalates, oxalates and oxamide.
3. It is used as an acidity regulator for synthetic adhesives such as urea-formaldehyde resin and melamine formaldehyde resin. Polyvinyl formaldehyde water-soluble adhesive can also be added to improve the drying speed and bonding strength. It is an important organic synthetic raw material and is used to produce various oxalates, oxalates, oxalamides, hydroquinone, quintetrate, mollic acid and other products. The pharmaceutical industry is used to manufacture aureomycin, oxyteramycin, tetracycline, streptomycin, ice tablets, vitamin B12, phenobarbital and other drugs. The printing and dyeing industry is used as a color dye and bleach. The plastics industry is used to produce polyvinyl chloride, amino plastics and urea-formaldehyde plastics. The metallurgical industry is used to produce high-purity nickel, carbon fine rods and precipitate rare earth metals. It is also used as a metal Detergent, tanning agent, chelating agent, catalyst, anaerobic adhesive and acrylic fast-fixing agent, machined rust remover, electroplating complexing agent, wood bleaching, marble cleaning and oil refining, etc.
4. It can be used as an additive to shampoo in cosmetics, mainly in the manufacture of chemical industry products; in the pharmaceutical industry, it is used in the manufacture of antibiotics and other drugs; it is widely used in the printing and dyeing industry and the leather industry; in oil chemistry, it is used as a refiner for turine alcohol, glycerin and stearate; in addition, it is used in the processing of aluminum products and cemented carbide production.
