Although the development of China's bearing industry has achieved certain results, the current problems can not be ignored, the most prominent is the low-end products, high-end products also rely mainly on imports. The development of high-end bearings in China is seriously out of line with the development of China's machinery and equipment. What is gratifying is that some companies that have accumulated and are committed to innovation have made breakthroughs in developing high-bearing products. For example, Luoyang Zhongyue Precision Bearing Co., Ltd. specializes in R&D and production of P4 and P2 high-end precision bearings. At present, the company's machine tool bearings, spindle bearings, high-speed bearings and other market competitive advantages, especially the machine tool bearings, product quality and imported products can be equivalent.
Based on the backward development of high-end bearings in China, the "Twelfth Five-Year" development plan that has been introduced clearly states that the state will play a guiding role in industrial policies to support the development of the bearing industry. Under the guidance of the state, the access threshold for the bearing industry will increase, the high-end production capacity of low-end products will be controlled, and the research and development of high-end bearings will enter the high-speed stage.
Potassium hydroxide, also known as lye is an inorganic compound with the chemical formula KOH. Also commonly referred to as caustic potash, it is a potent base that is marketed in several forms including pellets, flakes, and powders. It is used in various chemical, industrial and manufacturing applications. Potassium hydroxide is also a precursor to other potassium compounds. Potassium hydroxide is used in food to adjust pH, as a stabilizer, and as a thickening agent. This ingredient has been considered as generally safe as a direct human food ingredient by the FDA, based upon the observance of several good manufacturing practice conditions of use. In addition to the above uses, potassium hydroxide is also used in making soap, as an electrolyte in alkaline batteries and in electroplating, lithography, and paint and varnish removers. Liquid drain cleaners contain 25 to 36% of potassium hydroxide. Medically, potassium hydroxide (KOH) is widely used in the wet mount preparation of various clinical specimens for microscopic visualization of fungi and fungal elements in skin, hair, nails, and even vaginal secretions,. Recently, it has been studied for efficacy and tolerability in the treatment of warts. It was determined that topical KOH solution was found to be a safe and effective treatment of plane warts.
