| Introduction: |
At first, China Abrasives Import & Export Corporation (CAEC) was set up in 1981 as the largest state-owned corporation that specialized in abrasives and abrasive products in China. After nearly 30 years, it has developed into a conglomerate corporation that dabbling in abrasives, refractories, chemicals, minerals, metals, machineries, as well as processing trade, exports and imports complete sets of equipment and technologies.
CAEC is composed of two subsidiary companies, four stock-owned companies and four I/E business departments, has a professional, capable and efficient team which consists of Senior Engineer 21%, Engineer 64% and Assistant Engineer 15%. CAEC also has hundreds of cooperative suppliers and scientific research institutes.
Now, CAEC is the Chairman of China Abrasives Association, the Chairman of Artificial Corundum Branch and the Chairman of Sic Branch of China Chamber of Commerce of Metals Minerals & Chemicals Importers & Exporters.
The China National Machinery Industry Corporation (SINOMACH), to which CAEC is subordinated, was established in January 1971 with approval of the State Council. SINOMACH is a large scale, state-owned enterprise group under the supervision of the State Assets Supervision and Administration Commission. Its service covers a wide range of key national economic sectors including industry, agriculture, communication and transportation, energy, building, light industries, automobile, ship- building, mining, metallurgy and aerospace industries.

[Sell] Sedimentation agent for silicon carbide (SiC) micro-powder |
|
|
Our sedimentation agent is only specialized for the silicon carbide micro-powder which has a maximum particle size of 10 μm. It is a kind of non-smelly, non-toxic and non-corrosive liquid with light yellow color. It can effectively prevent such micro powders from being washed away in the acid-washing process by accelerating the sedimentation. And the sedimentation rate of the powder is about 2 cm per second. It is alkalescent and can only be used in the acid suspension that pH value is higher than 4. Also a higher than 10 °C temperature of the suspension is recommended so as to assure the activity of the agent.
Typical use amount:
Add 1kg sedimentation agent into per 10 tons suspension r which contains more than 0.20% SiC.
