HSA微硅粉

微硅粉 (硅微粉) 出售

微硅粉, 也称为微硅粉, are ultrafine powders collected as a by-product of the production of silicon and ferrosilicon alloys. Silica Fume particles are spherical and very fine, a property that makes them an excellent additive for concrete mixtures. They are widely used in high-rise buildings, refractory materials and other industries.

HSA成立于 2001, Silica fume is black or gray in color, and is available in several product forms and packaging options. Our products include:

未致密硅粉 ( 250~350kg/m³), SIO2: >85%, 92%,94% ,96%, 99%
致密化 (Compacted) 微硅粉 ( 550~700 kg/m³), SIO2: >85%, 92%,94% ,96%
White 94% 氧化锆微硅粉

We can also customize silica fume in various bulk density according to your needs.

HSA silica fume conforms to ASTM C1240, and is recognized by well-known testing institutions such as SGS.

未致密硅粉 (硅微粉)

未致密硅粉, 由冶炼过程中产生的大量高挥发性一氧化硅气体制成, 被空气迅速氧化并凝结成二氧化硅粉尘, 用于耐火材料, 肥料, 建造, ETC.

致密硅粉 (硅微粉)

致密硅粉, 是对原始微硅粉进行进一步加工，得到更致密的加密微硅粉, 常用于混凝土应用.
