Product Details

sillica powder price, SiO2 micronized silica amorphous silicon powder for matting

Product Description

The main ingredient of silica fume is amorphous Amorphous Silicon Powder, as the rising of furnace gas, there are some impurities, such as floating C, Fe2O3,CaO,K2O,Na2O and so on. The colors of silica fume range from hoary, grey to dark grey as the rise of C, Fe2O3 content.
At present the classification standards of silica fume industry is based on the activated SiO2 content, our product can be divided into 900D,900U,920D,920U,940D,940U, " D"means Densified," U " means half-desified or undesified.

Certifications

Our products high meets ASTM1240, SGS , ISO9001, tc stardards.

Advantages

1.Very low permeability to chloride and water intrusion.

2.Extremely high electrical resistivity.

3.Increased abrasion resistance on floors,highways,marin structures.

4.Superior resistance to chemical attack from chlorides,acids,sulfates.

Application

(1)Amorphous Silicon Powder can be blended into cement and concrete to improve the quality of concrete.

(2)It can be used as addition agent in the fireproofing material. Pure silicon powder has high fluidity, high strength.

(3)It is the adhesive of metallurgical pellet

(4)Very low permeability to chloride and water intrusion

(5)Extremely high electrical resistivity.

(6)Increased abrasion resistance on floors,highways,marin structures.

(7)Superior resistance to chemical attack from chlorides,acids,sulfates.

Packaging & Shipping

1.Regular products packing with a multilayer woven plastic ton bag each ton. Or with small bags(20/25/50kg) then into a ton bag.

2.Special product package with moisture proof bags.

3.Package with customers' requirement.

With a adequate capacity and convenient location(which is about 5 hours' way form Tianjin port),we would garantee a timely delivery to our customers.Usually with 14 days up receiving of an order.
