767-1AW，767-5AW are powdered activated carbons made of selected wood sawdust and is produced under strictly controlled chemically activation processes at a high temperature and acid washing refining. Through the introduction of advanced production equipment and technology from Japan, this series of carbon are specially developed by Xing Chang company for the applications such as pharmaceutical, chemical, food and beverage industries are characterized by high purity and high performance. Compared with the average medicinal activated carbon, 767-1AW and 767-5AW have better performance in the surface area, pore structure, adsorption effection, stability, impurities and filtration speed etc. After comparing in practical application, 767 - AW series products have been approved to be able to replace imported high-performance carbon in domestic market.
767-1 is a powdered activated carbon made of selected wood sawdust. Produced under strictly controlled chemically activation processes at a high temperature and acid washing refining, this carbon is characterized by large surface area, prosperous pores structure, perfect chemical stability, low impurity and Speedy filtration.
767-2 is a powdered activated carbon made of selected wood sawdust. It is produced under strictly controlled chemically activation processes at a high temperature and acid washing refining. This carbon is developed by Xing Chang Company and is a pharm grade activated carbon with special pores structure. Produced by special activation processes, 767-2 is characterized by more homogeneous pores structure distribution and better Selective adsorption ability than the other average pharm grade activated carbons in domestic market.
767-3 is a powdered activated carbon made of selected wood sawdust. It is produced under strictly controlled chemically activation processes at a high temperature and acid washing refining. Produced by special activation processes, this carbon is characterized by large surface area, prosperous pores structure, perfect chemical stability, low impurity and Speedy filtration.
767-1AW，767-5AW，767-1，767-2，767-3 are certified by SFDA (Shanghai Food and Drug Administration) and meet the related requirement of China Pharmacopoeia, and are widely used in the following applications.
