Silicon Powder Gelatinous material

In the industrial smelting smelting silicon, it will produce a lot of volatile strong silica gas, and these gases once discharged into the air will quickly condense into precipitated substances, micro-silica fume manufacturers to collect these substances , We became familiar with the micro-silica fume. Micro-silica powder is the appearance of white powder, do not look it is only a small powder, it does have a lot of role. The following micro-silica fume manufacturers for everyone to answer in detail.

     First, micro-silica fume will quickly generate gel-like material after encountering water, so it can be used to fill the gap between the cement. So the use of this powder in the building materials industry is very extensive. And the micro-silica fume fire resistance and high temperature resistance is also very good, which further enhance the safety of this material.

Second, micro-silica fume can be used as a refractory casting, such as breathable bricks, ladle and some high-temperature ceramics which we can add micro-silica fume, so that these materials will become very high temperature, in the processing time will change Very convenient. And the density and strength of this material are very high, plasticity is also very strong, so in the industrial field of application is very wide.

Third, the micro-silica fume and water reaction, and then dry and specific conditions of the firing, you can form a new smelting materials, and the impurities in this material is very small. Of course, if this can, this powder can also be used as fertilizer and fire extinguishing agent, and in the future believe that its use will be more and more widely, let us wait and see.

Mainly in:

(1) increase the strength. So that the concrete compression, bending strength greatly increased, infiltration 5-10% of the micro-silica fume, compressive strength can be increased by 10-30%, bending strength increased by 10% or more;

(2) increase the density. Impermeability increased by 5-18 times, the ability to improve resistance more than 4 times:

(3) frost resistance: micro-silica fume concrete after 300-500 times the rapid freezing cycle, the relative elastic modulus decreased by 10-20%, while the ordinary concrete through 25-50 cycles, the relative elastic modulus reduced to 30- 73%;

(4) early strength: micro-silica fume concrete to shorten the induction period, with early strength characteristics;

(5) anti-abrasion, controlled cavitation: micro-silica fume concrete than ordinary concrete anti-grinding ability to improve 0.5-2.5 times, anti-cavitation capacity increased 3-16 times. From the appearance of silicon powder and micro-silica fume is also relatively easy to distinguish, silicon powder its pure, color white, balanced particles, is a non-toxic, tasteless, non-polluting inorganic non-metallic materials; according to silica raw materials, Or the different furnace conditions, the vast majority of micro-silica fume was gray or dark gray. In the process of formation, due to the process of phase transition by the role of surface tension, the formation of non-crystalline amorphous spherical particles, and the surface is more smooth, and some are a number of ball particles together with the aggregates. White micro-silica fume is relatively rare, the past has been no suitable market positioning, has introduced white micro-silica fume, successfully applied to compound fertilizer, pesticides (as adsorbents, or the production of silicon fertilizer), paint, paint (as thickener, (As a reinforcing agent), plastic (as a filler), special ceramics, can replace white carbon black, but the number is relatively limited.
