- Scope
- This standard specifies the requirements, sampling, test methods, marking, packaging, transportation and storage of fine-porous silica gel. This standard applies to fine-pore spherical silica gel and fine-pore block silica gel made from sulfuric acid and sodium silicate as raw materials. Fine-pore spherical silica gel is mainly used as gas purifier, desiccant, air temperature regulation and catalyst carrier, and is used in petroleum In the refining of products, fine-pore block silica gel is mainly used for the refining and separation of petrochemical products and the dehydration and refining of organic products. Molecular formula: SiO|(2)·nH|(2)O
