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.
Abrasive grains can be divided into two categories: natural abrasive grains and artificial abrasive grains. All natural materials that can be used for grinding or grinding are collectively referred to as natural abrasives. Artificial abrasives can be divided into corundum series, carbide series, superhard series, etc. We provide relevant products of passive grains. If you are interested in this, please take the initiative to contact us for more information.
There are many kinds of passive grains, which are generally classified according to their hardness. The highest hardness is diamond, including synthetic diamond and natural diamond; The second is carbide, such as black silicon carbide, green silicon carbide, boron carbide and carbon silicon boron, etc; The third is corundum with high hardness, such as brown corundum, white corundum, single crystal corundum, chrome corundum, microcrystalline corundum, black corundum, zircon corundum and sintered corundum.
Silicon carbide abrasive grains are divided into black silicon carbide and green silicon carbide, which are obtained by heating silicon carbide and carbon in an electric resistance furnace. Silicon carbide has good thermal conductivity and low coefficient of thermal expansion. Compared with green silicon carbide, black silicon carbide has higher hardness and lower toughness. In addition, they can also be distinguished according to their colors, for example, those with silicon carbide content of 96-99% are black; Those with more than 99% silicon carbide are green.
White corundum abrasive grains are commonly known as emery, also known as alumina grinding powder. It is a white corundum crystal block obtained by smelting aluminum oxide powder in an electric furnace, crushed and sorted according to the particle size standard. White corundum and brown corundum are both corundum abrasives, and their difference lies in the content of alumina crystals.
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.
