Silica Products
Silica, (SiO2, gel, xerogel or aerogel, chemical composition of SiO2-xHO) in the field of chemical industry in addition to being used as adsorbents, desiccants, an important application area is used as catalysts and catalyst carriers. The preparation technology of silica gel carrier is one of the core technologies for the production of polyolefin catalysts, which requires it to have a certain stack density, specific surface and pore structure. In the research and application of polyolefin catalyst carriers, silica gel plays an irreplaceable role.
The central role of carriers:
1、hemical role a .Solid and dispersed metal active component; b.The important ligand of the active component.
2、Physical Role a. Strength controls crushing in catalyst preparation; b. Particle size and pore structure control crushing and diffusion behavior; c. Pore structure controls polymer structure and properties; d. Morphology controls polymer particle morphology; e. Strength controls crushing behavior in polymerization; f. Particle size and particle size distribution control flow and mixing.
