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.

Solubility (20 ℃) | 50 | 50 | The number of grams that can be dissolved in 100 grams of water, a small amount of which can be dissolved for many times. |
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.
