Silicasol is the aqueous dispersion of nano silica, and nano particles have huge specific surface area, which can produce good adsorption. This time, Baite New Materials will introduce the key points for using silica sol.
Baite New Material Reminder: Key Points for Using Silicone Sol
1. The selected silica sol is acidic and meets food hygiene standards.
2. Silica sol must be added before gelatin. If other clarifying agents such as carbon, bentonite, etc. are used, they also need to be added before adding silica sol, leaving sufficient reaction time.
3. When using silica sol for clarification, the temperature should be ensured to be above 10 ° C.
Shandong Baite New Materials Co., Ltd. focuses on producing nano dispersions. The main products include silica sol, acidic silica sol, neutral silica sol, high-purity silica sol, polishing solution, and so on. Welcome to inquire

Silica sol: What are the key points for using silica sol
Silicasol is the aqueous dispersion of nano silica, and nano particles have huge specific surface area, which can produce good adsorption. This time, Baite New Materials will introduce the key points for using silica sol.
Why does silica sol have storage stability?
Silicasol is the dispersion of nano silica, and the particle size of nano particles is generally 3-150nm. The density of nano silica in silica sol is 2.2-2.3, while the density of water is 1, with a significant difference in density. However, we observed that silica sol can maintain suspension stability for a long time. Why is this?
Precautions for the use of silica sol
Although silica sol can maintain suspension stability for a long time, some precautions should be taken during storage, otherwise irreversible damage may occur.
Structure and stability of silica sol
Silica sol is a dispersion of nano silica particles in water or solvent. Silica sol is widely used in CMP polishing fluids, special coatings, papermaking, textiles, precision casting, refractory materials, catalyst carriers, precision ceramics and other fields.
