Quick drying silica sol: the film used forcasting shell can quickly dry the shell of the product. According to thedifferent high temperature strength, colloidal silica for precision casting canbe divided into the surface layer obt830 colloidal silica and the back layerobt1430 colloidal silica. This product has a transparent appearance, which cangreatly improve the efficiency and stability of the shell quality. It is moresuitable for the application of automatic shell production line, cansignificantly improve the drying speed of shell film, shorten the constructionperiod and save costs.
Accession It is used as binder of variousfire-resistant materials. It has high bond strength and high heat resistance(1500-1600c).
Accession Used in coating industry. Itmakes the paint firm. It also has the functions of anti pollution, dustproof,anti-aging, fire prevention and so on.
Accession It is used in the precisioncasting of thin coating to improve the strength of the coating and the finishof the casting. Its forming quality is better than that of water glass. It canbe used to replace ethyl silicate for molding, so as to reduce costs andimprove operating conditions.
Accession Silica sol has large specificsurface area, which can be used to prepare catalyst and support catalyst.
Accession Used in paper industry. It can beused as anti adhesion agent of cellophane, pretreatment agent of photosensitivepaper, antiskid agent of cement bag, etc.
Accession Used as sizing agent in textileindustry. When processing wool and rabbit hair together with photo paper oiland antiskid agent, it is helpful to improve the processing performance of wooland rabbit hair and reduce the economic loss.
Accession It can be used as treating agentof silicon steel plate, dispersing agent of picture tube and antiskid agent offloor wax.
Accession Silica content is 40% of basicsilica sol, which can be used for refractory and polishing
Accession Ammonia stabilized silica sol ismainly used for ceramic fiber and catalyst support.
