CONSTITUTION:The cutting tool is formed by coating the surface of a ceramic substrate with a surface hard layer having 0.1-10mum mean thickness by chemical or physical vapor deposition. The ceramic substrate contains, by volume, 5-40% aluminum oxide and the balance of >=1 kind among the ...
Disinfectionmeans a process which inactivates pathogenic organisms in water by chemical oxidants or equivalent agents. Anaerobic digestermeans a liquid manure storage area that is constructed with the intent to capture and combust gas emissions resulting from the digestion of waste by microbes in anaerob...
Chemical Precipitation. If physical separation techniques do not work, separation may be achieved by chemical conversion to a soluble precipitate. Ion Exchange. Certain solid substances have the property of exchanging one ion for another if placed in a solution containing the ions. Typical substances ...

The purpose of this Group Standard is to determine a standardized test for evaluation of the chemical and physical suitability of the material. 此标准目的在于定义评价材料的化学和物理适用性的测试标准。 The range of the parts to be tested must be coordinated with the respective specialist department...
A robust superhydrophobic surface needs to be able to resist chemical, and mechanical damage, while demonstrating overall thermodynamic stability. If the geometry or surface chemistry is compromised, then the surface properties will degrade and superhydrophobicity will be lost. Self-healing surfaces and ...
