Product Description

 

Product Description

 

Silica fume, also known as microsilica, It is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production. Silica fume is an ultrafine material with spherical particles less than 1 μm in diameter, the average being about 0.15 μm, which have supperpower activity index. This makes it approximately 100 times smaller than the average cement particle. The bulk density of silica
fume depends on the degree of densification in the silo and varies from 100kgs/m3 (undensified) to 720 kgs/m3
The main field of application is concrete, grouts and mortars as well as refractory, cearamic ,oil well grouting, shotcrete,repair products.

Silica fume in repair products
Silica fume is used in a variety of cementitious repair products. Mortars or grouts modified with silica fume can be tailored to perform in many different applications-overhead and vertical mortars benefit from silica fume's ability to increase surface adhesion. Silica fume dramatically improves cohesiveness making it ideal for use in underwater grouts, decreases permeability in grouts used for post-
tensioning applications and increases the resistance to aggressive chemicals.

Company Profile

SY (SanYuan ) company started to research and promote microsilca since 2001,then we built the production plant. except the original Yinchuan factory, Gansu Sanyuan has established a new"Lanzhou factory". It has also
upgraded the Yinchuan factory, result in made the Yinchuan factory safer, more technological, more efficient, and more environment-friendly (add a full set of environmental protection equipment and add the screening and classification functions of the original equipment). Our company has added the Tianjin Distribution Center on the basis of the original three storages of "Gansu, Ningxia and Inner Mongolia", achieving secondary quality inspection and fast transportation.
We have been producing and selling microsilica nearly 20 years. So we are very professional and experienced in this filed. Our annual production capacity is over 100,000 tons. Sanyuan is one of the industry leaders of microsilica
products in China for decades, mean while we participated in the drawing of Chinese national standard for microsilica.
