Mono Calcium Phosphate ,the chemical formula is Ca (H2PO4)2.H2O, molecular weight of the body is 252.06, after dryed the product is white or slightly yellow micro powder or granules, the relative density of 2.22 (16 °C). Slightly hygroscopic, soluble in hydrochloric acid, nitric acid, slightly soluble in cold water, almost insoluble in ethanol. At 30 °C, 100 ml of water soluble MCP 1.8g. The aqueous solution was acidic, heating the aqueous solution can get calcium hydrogen phosphate. Lose crystal water at 109 °C and decomposed into calcium metaphosphate at 203°C. Applications:Monocalcium Phosphate is used to supply mineral nutrition such as phosphorus (P) and calcium (Ca) for animal, which can be easily digested and absorbed. Extensively applied as additives of Phosphorous and Calcium in aquatic animals feed.Higher water solubility of MCP is required in aquatic animals feed.

Among them, the newly introduced VEC spatial error compensation technology is particularly noticeable. Ms. Wang Wei, chief representative of API China, said in an interview with China National Machinery and Metal Processing Network that VEC's spatial error compensation technology is a calibration method that can improve the accuracy of machine tools in a shorter time. This technology uses an API laser tracker in conjunction with an Active Target moving target to perform compensation measurements on the machine tool in a shorter period of time. "The VEC technology uses a laser tracker and moving targets to accurately compensate for machine tool errors by taking points and establishing motion error models. Its measurement range covers the entire processing area. Compared with conventional laser interferometers, it has an error in machine tools. The compensation accuracy can be improved 3-4 times, and the efficiency is greatly improved.†Ms. Wang Wei said: “VEC technology is not limited by the size and structure of the machine, and can quickly complete the calibration of the machine tool, including five-axis, six-axis Large-scale machine tools, which guarantee high-precision positioning, are breakthrough innovations and practical methods for calibration of large-scale machine tools.â€
API Corporation is a world leader in high-precision standards for coordinate measurement and machine tool performance testing. The company is the world's first manufacturer of commercial laser trackers and the only manufacturer of six-dimensional laser trackers and six-dimensional laser interferometers. The company's products include laser trackers, laser interferometers, high-precision three-dimensional scanning probes, intelligent probes, rotary shaft angle pendulum testers, etc., and are widely used in aerospace, railway, automotive, electric power and other fields.
Ms. Wang Wei told the author that the API brought the concept of the tracker to China for the first time, but at the same time, she also admitted that compared with the competitors, the API entered the Chinese market much later. “In spite of this, our development speed is very fast, increasing by 30%-40% every year. In the past 2009, API occupied 60% of the market share of China's laser tracker industry, and so far this year, our Sales have been the same as last year."
Wang Wei said that he is very optimistic about the Chinese market. “With the acceleration of domestic large-aircraft projects, high-speed railways, wind power, and nuclear power construction, as well as the user’s increased awareness of trackers, the market is also growing.†According to reports, API is wholly-owned in Chengdu. Established a production base - Ai Peiyi Zhongjian (Chengdu) Precision Instrument Co., Ltd., "AiPeiYi ZhongMei will spare no efforts in research and development of cantilever coordinate measuring technology to improve the ability to quickly respond to the market. Next, we hope to be able to Do something and continue to introduce advanced measurement products that meet the diverse needs of users.â€
