other uses of microsilica-pg电玩城

in the production process of ferroalloy plants, industrial silicon and ferrosilicon will discharge a large amount of high-temperature exhaust gas with dust during the high-temperature melting process. the exhaust gas directly discharged into the atmosphere will cause serious environmental pollution, and the main content of dust in the exhaust gas is sio2 dust, which is a fine spherical particle formed by condensation of high-temperature vaporized sio2, which accounts for about 90% of the weight. the silicon powder is an important raw material, and it can be widely used in construction engineering, hydraulic engineering, refractory materials, etc., and the market prospect is extremely broad. therefore, the treatment of exhaust gas and the collection of silicon powder are good things that are both environmentally friendly and of high economic value.

 application of microsilica on refractory materials: as a new raw material, silicon powder is commonly used in the refractory industry. it plays an important role in the improvement of amorphous refractories. expressed as:

1. there are many pores in the traditional refractory material, and the micro-silica powder is filled in the pores, which increases the bulk density and reduces the porosity, and the strength can be obviously enhanced;

2. microsilica powder has strong activity, can form colloidal particles in water, and adding proper amount of dispersing agent can enhance fluidity and improve pouring performance;

3. micro-silica powder is easy to form in water - si-oh group, has strong hydrophilicity and activity, can enhance the coagulation of refractory materials, and at the same time greatly improve the high temperature performance, and can prolong the service life of refractory products. .

other uses of microsilica:

1. cement industry: after adding micro-silica powder to cement, the performance is improved, and the quality and label are greatly improved;

2. rubber industry: after adding a certain amount of micro-silica powder, the rubber has a large shrinkage, tear resistance and anti-aging degree. the rubber also has good dielectric properties and low water absorption capacity;

3. as an anti-caking agent: instead of mica or diatomaceous earth as a raw material to prevent agglomeration of fertilizer particles;

4. as a pellet binder: microsilica powder has a large specific surface area and strong adsorption, and has achieved remarkable effects as a binder for pellets in foreign countries;

5. water glass industry: can replace the quartz mine to produce water glass with a modulus of 4;

6. in the oilfield as a cementing use: jilin oilfield, liaohe oilfield, karamay oilfield, etc., all use micro-silica powder and achieve good use effect;

7. applications in insulating materials, waterproof materials, paints, coatings, printing industries, etc.

  the promotion and application of micro-silica powder marks the entry of china's construction industry and ceramic refractory production into a high-tech period. in the 1980s, the application of micro-silica powder also led to the application of other micro-powders. with the development of the market, the construction industry, ceramics and refractory materials are increasingly demanding, and their special physical and chemical properties of micro-silica powder will be more favored by the market, and the application prospect is very broad. in recent years, micro-silica powder has been applied in the construction and building materials industries, achieving very desirable results, and its use is becoming more and more extensive.

the application of ceramics and refractory materials for micro-silica powder can greatly reduce the amount of water used for casting, greatly improve the strength and density of castables, and even improve product quality and improve product life. it is the most ideal binder and performance improvement blend. .
