Specifications of Silica Powder Sand
Use in abrasive, glasswork, cast steel, precision foundry,sand blasting, remove rust, charging, refractory, pesticide use, rubbe

Fused Silica is made of high purity Chinese crystal Silica by electrically fusing (fusing temperature 1800-2000 degrees centigrade) to amorphous Silicon dioxide, then by alumina ball mill grinding, unique air classifying, screening, magnetic and other impurity seperating techonology, designed for EMC and other electrical application.

Use in abrasive, glasswork, cast steel, precision foundry,sand blasting, remove rust, charging, refractory, pesticide use, rubber,dope, waterproof, antisepticise, abrasive ground, made ground, water treat, felt and so on.

The nature of these two sand is different.
Q:Ordinary concrete mix design rules JGJ55-2011 in the sand material 28d compressive strength is what glue
More to see the specification to know: "cement mortar strength test method CISO method" GBjT; do cement mortar strength of the standard method, the new specification should be the strength of cement mortar material should be containing the admixture, anyway it has Conversion value, if the strength of the cement can also be calculated!
Q:Hello, I am the general taxpayer to do gravel, how much is our tax point
57) 6% to 3 of the State Administration of Taxation of the Ministry of Finance on the basis of the following measures The small hydropower generating units are small hydropower units with the installed capacity of less than

) and calcium material (lime, cement) as the main raw material, mixed with gas agent (aluminum powder) Porous concrete products made by stirring, pouring, pre-feeding, cutting, autoclaving and other processes are widely used in new wall materials
Q:Asbestos in the industry why the application of such a light, its use which
It is an important fireproof, insulated and insulated material with high fire resistance, electrical insulation and thermal insulation. However, asbestos fiber can cause asbestos lung, pleural mesothelioma and other diseases, many countries have chosen a comprehensive ban on the use of such dangerous substances.
Q:Is there any more advanced material to replace the mortar king?
You say if it is waterproof mortar, then still continue to use waterproof mortar to do kitchen and toilet water and other areas of waterproof materials.
