What is sodium silicate? Sodium silicate (Na2O · nSiO2), known as partial alkali, is an inorganic substance with a colourless, slightly coloured translucent or transparent massive vitreous body. It is mainly used as filler, fabric fire retardant and adhesive. Hazard symbol R36 / 38; Hazard Description Xi; UN Dangerous Goods No.2922. The state can be divided into two categories: liquid sodium silicate and solid sodium silicate. Liquid Na2O · nSiO2 is distinguished according to the different proportions of quartz sand and alkali and the different types of alkali. It is a viscous liquid with different colours showing significantly different grades, and its appearance mainly changes from colourless to grey and black. There are many properties, such as: neutral Na2O · nSiO2, alkaline Na2O · nSiO2, weak alkaline Na2O · nSiO2, compound Na2O · nSiO2, etc.
The solid-state Na2O · nSiO2 is an intermediate product, coloured in mostly light blue colours. The Na2O · nSiO2 made by different methods has a different appearance. The Na2O · nSiO2 formed by dry casting is massive and transparent, while the Na2O · nSiO2 formed by water is granular in appearance and can only be used in liquid Na2O · nSiO2. There are many common Na2O · nSiO2 solid products, such as block solid, powder solid, instant sodium silicate, zero water sodium metasilicate, five water sodium metasilicate, and sodium protosilicate.
Main uses of sodium silicate Sodium carbonate mainly has five uses: 1. sodium silicate is the most valuable filler in the soap industry. The sodium silicate in laundry soap can buffer the alkalinity of laundry soap, reduce the loss of laundry soap in water, and can enhance the washing ability and prevent the soap; 2. sodium silicate in synthetic detergent to help washing, corrosion, stable foam role; 3. can be used as paper packing; 4. used to manufacturing silicon gel, silica gel; 5. used in the casting industry adhesive, bonding sand and clay into various casting and type cores.
As a water glass, there are seven main uses: 1. Water glass coated on the metal surface will form alkali metal silicate and SiO2 gel film; make the metal free from external acid, alkali and other corrosion; 2 used as a binder for bond glass, ceramics, asbestos, wood, plywood, etc.; 3. To manufacture refractory materials, white carbon black, acid-resistant cement; 4. Used as a slurry and dip agent in the textile industry, Used as fixation and media in textile dyeing and embossing, and used for silk fabric aggravation; 5. By adding water glass to the leather production, Its dispersed colloidal SiO2 is used to produce soft leather; 6 It can be used to preserve eggs in the food industry, Prevent microorganisms from entering the eggshell space and causing deterioration; 7 In the sugar industry, Water glass can remove the pigment and resin in the sugar liquid.
