Introduction of water-soluble silicon phosphate
I, Preface
Due to the existence of alkali metal ions that are easily soluble in water, the water soluble alkaline substances remain after curing, so the water resistance of water glass is poor, easy to regain moisture, and is not suitable for wet environment. Therefore, water glass based materials must be added with certain curing agent to improve their water resistance and curing performance. Common curing agents include metal oxides, inorganic acids, fluorosilicates, etc. However, there are still many imperfections in the use of these curing agents. For this reason, a new type of curing agent, water-soluble silicon phosphate, was developed on the basis of the original curing agent.
II, Product characteristics
Water glass curing agent - water-soluble silicon phosphate is a white powder that can be dissolved in water and is environmentally friendly. It does not melt into colloid at high temperature. Silicon phosphate curing agent has the characteristics of high curing efficiency, environmental protection and high temperature resistance.

IV, Product features
(1) The product is non-toxic or low-toxic, and the production process is pollution-free.
(2) The curing speed is moderate and there is no early setting or non-condensing phenomenon.
(3) After curing, the performance is better than that of the previous curing agent and reaches the industry standard.
(4) It not only effectively overcomes the shortcomings of traditional curing agent, but also has no pollution and conforms to the environment The need for protection.
V, Scope of use
In addition to being used as sodium silicate curing agent, silicon phosphate can also be used as lime curing agent and cement curing agent; Special optical glass; Inorganic coating; Ingredients of high-strength cement and acid-resistant adhesive; Waterproof adhesive curing agent; Non-toxic antirust coating and organic synthesis catalyst.
VI, Usage and dosage
6.1 Mixed method
6.1.1 Application process: first dissolve silicon phosphate with a small amount of water for many times, and then directly add it into water glass or other material media to stir evenly; Silica phosphate can also be soaked with a small amount or the powder can be directly added to water glass solution or other material media and stirred evenly.
6.1.2 Dry process: silicon phosphate powder and sodium silicate powder can be mixed directly and used evenly.
6.2 Dosing recommendation
The water glass can be sealed and stored after adding curing agent. The general dosage is about 3-10% of the liquid water glass dosage (the specific dosage is adjusted according to the process).
VII, Packaging and storage
25kg/bag,1000kg/bag plastic woven or kraft paper bag. Store in a cool, dry and ventilated place.
