Black silicon carbide F240 F320 mesh for engine lubricating oil
The main functions of engine oil are lubrication, cooling, rust prevention, sealing, etc. The main purpose of lubricating oil is to lubricate the engine, reduce engine wear, lower engine temperature, and prevent parts from rusting. At the same time, the oil also needs to maintain appropriate viscosity, dispersibility, and high-temperature stability. Black silicon carbide powder is a wear-resistant, oxidation-resistant, high-temperature-resistant, and high thermal conductivity material. Black silicon carbide F240 and F320 can greatly help the function of motor oil. Specifically reflected in the following aspects:
Black silicon carbide powder has good oxidation resistance. Especially at high-temperature, it still has excellent oxidation resistance. The melting point of silicon carbide is 2600 degrees. It can be used normally at a temperature of 1900 degrees. Maintain very stable chemical and physical properties below 1600 degrees. As a result, the particle surface will not undergo oxidation reactions. Therefore, when working in automotive and diesel engines, the black carborundum microns in the engine lubricating oil improves chemical stability and corrosion resistance.
Black silicon carbide powder has high thermal conductivity. The thermal conductivity of black silicon carbide is 60-200 W/(M · K). So, it can not only withstand the high temperature during engine operation but also transmit the generated high temperature. Moreover, it will reduce the impact of high temperatures on lubricating oil performance.
Black silicon carbide powder has good high-temperature stability. Thus it is not easy to react with other substances even at high temperatures. It will not cause oxidation reactions in lubricating oil, preventing the generation of acidic substances and precipitates in the engine oil.
Black silicon carbide powder has high wear resistance. The microhardness of black silicon carbide is 28-33GPa, and the Mohs scale hardness is 9.2. Under the conditions of high temperature and high pressure, the engine oil forms an oil film with wear resistance on the engine friction surface, which is due to the black silicon carbide powder.
The quality of black silicon carbide powder added to the engine oil and lubricating oil is good. Mainly reflected in the SiC purity, flowability, and cleanliness of black silicon carbide powder. High-purity silicon carbide ensures the physical and chemical properties of the added material. Silicon carbide powder with good fluidity can fully mix with engine oil evenly. It can reach various contact surfaces of the engine. Silicon carbide powder with good purity will not cause additional pollution to the engine oil.
HAIXU black silicon carbide F240/F320 (JIS320 # 400 #) adopts a series of complex cleaning and screening processes to control the quality. It meets the requirements of the European standard FEPA. Other types of black silicon carbide such as dust extraction powder and milling silicon carbide powder can’t make the job.
