High purity precision casting colloidal silica sol acidic

1. sol for precision casting of thin, can cover strength, casting finish, with its shape better than the quality of the water glass shape, the shape of inexpensive off than ethyl silicate.
2. sol used in the coatings industry, the coating firm, good adhesion properties, but also dirt, dust, crack, fire and other functions.
3. sol silicate refractories used for a variety of binder has strong adhesive, high temperature (1200 ℃) Zhu advantages.
4. sol textile industry as a thickener, greatly improving the economic efficiency it with oil, and for the processing of wool, wool can improve spinnability, reduce breakage. Prevent fly, to improve the yield and if used the veil slurry, the slurry can be improved adhesion, and easy to drop slurry, drying time is shortened, etc. sol make wool fabric (such as carpet) modified to prevent contamination.
5. due to the larger surface of the silica and catalytic activity, it is suitable for the catalyst carrier, for example 40% SiO2 silica sol used in the production of the catalyst C41 ABS plastic carrier.
