Application
1. The detergent builder. ISS and 4A Zeolite complementary in terms of functionality, both at a reasonable mixing ratio, can completely replace the detergent in STPP. Either before spray-drying production of ordinary detergent ingredients can also be adopted as the basis of powder agglomeration concentrated detergent production, product flow is good, no clumping, no caking, strong detergency.
2. Washing pastes, laundry detergent additives. With the surfactant and bleach compatibility is good, not hydrolysis, no precipitation.
3. Wash meal builder. Oil absorption value up to 70%, the ability to replace oil hydrated sodium silicate (oil absorption value 38%).
The industrial cleaning agent additives. ISS is a metal cleaning agent, heavy oil cleaner, oil drain cleaners, cleaning agent bottles bottles of various cleaning agents are important components, strong detergency, but also the effect of corrosion and rust.
5. Direct cleaning oil. ISS without surfactant can fit directly transferred into the appropriate concentration of the aqueous solution to be cleaned of oil.
6. ceramics, cement, refractories, grinding enhancer. ISS has a unique pour depolymerization effect, in ceramic, cement, refractories milling production, can effectively reduce fine grinding time and increase strength and cement grade embryo.
7. A building cement additives, dispersants.
8. plating rust polishing agent, PH value buffer.
9. yarn cooking, paper bleaching, textile finishing agent.
10. Crude oil, natural gas and underwater drilling projects as adhesives and cement dispersants.
11. The metal corrosion rust inhibitor.
12. The blast furnace maintenance, masonry adhesive.
13. production aids special lubricants, thixotropic agent.
14. Glass enhancer.
Instant Powdered Sodium Silicate
Product Name: Instant powdered sodium silicate, also known as instant sodium silicate, sodium silicate hydrate.
Formula: Na2O? NSiO2? NH2O, the molecular weight is generally between 280-350.
Appearance: The appearance of white, in powder form, good uniformity.
Uses: Widely used in metallurgy, electric power, petrochemical and building materials industries. It is used as a binder in monolithic refractories, industrial cleaning agents, preservatives, the soap and acid-proof cement, fine ceramics industry and casting industry, drying agent and enhancer, transport, storage and use very convenient, especially for mechanization and automation. Instant powdered sodium silicate products also have all the properties and applications of liquid sodium silicate has.
