Finished the aluminum alloycomposite material technologyscheme and accumulatedexperience.
By improving the production process,the product technology has beenupgraded.
The company was established, andtwo new production lines were putinto use.
Dongguan Ruihui Surface Treatment Materials Co., Ltd. was established on January 4, 2017 with a registered capital of 1 million Yuan, the building area is about 1200 square meters, and there are about 30 employees. It is a comprehensive enterprise specializing in the production of surface treatment materials. The company integrates production, research and development, sales and service.
It continuously absorbs advanced production processes at home and abroad, and establishes a sound quality certification system in accordance with ISO9001 standards. It has complete experimental facilities and advanced physical and chemical testing equipment, manufacturing white corundum abrasive products. Widely used in semiconductors, refractory materials, ceramic materials, electronic chemicals, grinding and polishing, precision casting, building materials, petroleum, aerospace, military and other manufacturing fields.
α- SiC forms many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, and more than 70 varieties have been found. β- SiC transforms to α- SiC。 The industrial production of silicon carbide is made by refining high-quality quartz sand and petroleum coke in an electric resistance furnace. The refined silicon carbide blocks are processed into products of various particle sizes through crushing, acid and alkali washing, magnetic separation, screening or water separation.
Silicon carbide has two basic varieties: black silicon carbide and green silicon carbide α- SiC。 ① Black silicon carbide contains about 95% SiC, and its toughness is higher than that of green silicon carbide. It is mostly used to process materials with low tensile strength, such as glass, ceramics, stone, refractories, cast iron and non-ferrous metals. ② Green silicon carbide contains more than 97% SiC and has good self sharpening property. It is mostly used for machining cemented carbide, titanium alloy and optical glass, as well as for honing cylinder liners and finishing high-speed steel cutters. In addition, there is cubic silicon carbide, which is a yellow green crystal made by a special process. The abrasive tools used to make it are suitable for ultra precision machining of bearings, and can make the surface roughness from Ra32~0.16 μ m to Ra0.04~0.02 μ m.
Silicon carbide has stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance. Besides being used as an abrasive, it has many other uses. For example, coating silicon carbide powder on the inner wall of the turbine impeller or cylinder block with a special process can improve its wear resistance and prolong its service life by 1~2 times; The high-grade refractory material made of it has the advantages of heat shock resistance, small size, light weight, high strength and good energy saving effect.
Pure silicon carbide is colorless and transparent crystal. Industrial silicon carbide is light yellow, green, blue or even black due to different types and contents of impurities, and its transparency varies with its purity. SiC crystal structure is divided into hexagonal or rhombohedral α- SiC and cubic β- SiC。
The product is very perfect, the quality is excellent and very durable, the manufacturer's delivery speed is very fast, and I look forward to continuing to cooperate next time.
Your company is strong, the logistics speed is very powerful, and the delivery time is accurate. I highly appreciate this cooperation and hope to continue to cooperate with your company for a long time!
They are a very strong company with accurate delivery times and guaranteed product quality! The receptionist was very kind and patiently answered our questions!
Firstly, We make sure the quality before the goods to be packed, if clients get the item with Substandard products, We have warranty for our clients,we will ship out the new replacements.
Al2O3 alumina is the starting material of aluminium production, both of metallic aluminium and aluminium oxide. It is porous an has a large reactive surface.
The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).
Generally, we suggest to make shipment by sea which costs less. We also can follow other transportation method you asked.
