| SM Powered Fast-dissolving Sodium Metasilicate (series) |
 |
Powered Fast-dissolving Sodium Metasilicate (Na2O·nSiO2·H2O.The value of n changes with the size and purpose)is adapt to different scopes.
This product is mainly applied as spraying complement ingredient for kilns, casting ingredient,acid proof daub , and as adhering agents used in other unshaped refractory . It is also employed as bond in casting , pottery , coating and insulating materials . It is not only needed as quick drying agent and reinforcing agent in common cement and used as thickening agent and water blocking agent in oil extraction industry as well . It is often found as degreasing agent , filling agent and corrosion inhibitor in synthetic detergent . |
