Special mold silica sol for precision casting

Main purpose

This product is a kind of silica sol product designed for precision casting. The shrinkage of EPC casting is very suitable for the whole surface layer. The shell made it has a surface layer

The production of EPC Castings has the advantages of high smoothness high temperature compressive strength, which significantly improves the qualified rate of castings. .

an instruction manual

In the vertical mixer, first add wetting agent defoaming agent, then add silica sol, stir evenly, then add resistance in the continuous mixing

Fire powder, mix again until the management system is sufficient stable, measure its viscosity, if the management system viscosity is too high, add silica sol diluent; if the management system

If the viscosity is too low, add proper fireproof powder until the viscosity is appropriate.

Packaging storage

1. High density polyethylene drum is selected for packaging, the key packaging specifications models are 25kg 250kg. .

2. Store in a temperature of 0-40 "C to prevent exposure to the sun. If the temperature is less than 0 ° C, the gel will be invalid.

3. Prevent the open type contacting with gas for a long time.
