What are the main research progress of coal powder silica?
At present, from a technical point of view, the research progress of coal-coke stone-made silica in my country is mainly to use acid leaching slag, high-temperature calcination, aluminum slag and other methods to process coal-made silica.
The results show that the process conditions of the white carbon black product prepared by the carbon decomposition method are: (NN0):n(SiO,)=1.5, and the mass concentration of the sodium silicate solution is 1.07g/cm2. Additive alcohol can improve the dispersibility of silica, PEG can improve its hydrophobicity, CTAB can improve its dispersibility, so as to obtain products with small particle size and high DBP absorption rate. The composite effect of polyvinyl alcohol and CTAB, the addition amount is 4.1.11×10, 9×10, 8×10’mol/L respectively, the particle diameter of silica is ≤4.5m, and the small is 2.77um. The product has good dispersion performance and strong hydrophobicity, and can be used as a filler for polymer materials with excellent performance.
What are the benefits of silica complete equipment?
What is the specific use of the silicone complete set of equipment and what is the value of the market, entrepreneurs and scholars have been thinking hard and prepared a lot of materials.
(1) Silica-silane and raw materials can help reduce the rolling resistance of tires, effectively reduce vehicle fuel consumption, and reduce carbon dioxide emissions.
(2) The zinc-loaded inorganic agents and coatings of silica have good bacteriostatic properties, and have good inhibitory effects on Escherichia coli and Staphylococcus aureus.
(3) Silica gel manufacturers can effectively improve the road performance of SBS-modified asphalt and asphalt mixtures, especially for improving the storage stability of SBS-modified asphalt.
