Product Description

Quartz sand have higher fireproof performance, admiral industrial quartz sand is often divided into: ordinary quartz sand, fine quartz sand, high purity quartz sand, fused quartz and silicon powder, etc.

1, ordinary quartz sand; SiO2 90-99% Fe2O3 0.06 or less - 0.02% or higher, refractoriness 1750 , the exterior part of the larger particles, the surface has a yellow skin cyst. Particle size range 5-220 mesh, grain production according to user requirement. Main application: metallurgy, silicon carbide, glass and glassware, enamel, cast steel, water filtration, paohuajian, chemical industry, spray noisy and other industries.

2, the refined quartz sand; SiO2 99-99.5% Fe2O3 0.02 or less - 0.015% or higher, select high-quality complex ore processing. 5-480 mesh size range, can be produced according to the requirements of customers, appearance white or crystal. Main use: senior glass, glass products, refractories, smelting stone, precision casting, grinding wheel grinding materials, etc.

3, high purity quartz sand; SiO2 acuity 99.5-99.9% Fe2O3 0.005% or less, is to use level 1-3 natural crystal and high quality natural stone, carefully selected, fine processing and into. Particle size range 1-0.5 mm, 0.5 -- 0.1 mm, 0.1 0.01 mm, 0.01 0.005 mm, can be produced according to the requirements of customers. In millimeter (mm)

4, fused quartz sand; Chemical composition: SiO2 99.9 99.95%; Appearance is colorless transparent block, granular or white powder. Relative density: 2.21; Mohs hardness: 7.0; PH: 6.0;

5, silicon powder; Appearance is gray or gray powder, refractoriness > 1600 . Density: 200 ~ 250 kg/m3.

6, color quartz sand; Main raw material is quartz sand, through the industrial fuel processing, became the dye color sand.

Application area

 

1. is used in mortar and concrete: high-rise buildings, Seaport Wharf, Reservoir Dam, Water Conservancy, culvert, railway, highway, Bridge, Subway, tunnel, airport runway, concrete pavement and coal mine roadway anchor spray reinforcement.

In the 2. materials industry: (1) High-grade high-performance low-cement refractory pouring and prefabricated parts, the service life is three times times the ordinary castable, fire resistance increased by about 100 ℃, high temperature strength and thermal shock resistance are significantly improved.

has been widely used in: Coke oven, ironmaking, steelmaking, steel rolling, non-ferrous metals, glass, ceramics and power generation and other industries.

(2) Large iron ditch and ladle material, breathable brick, smear repair material and so on.

(3) Self-flowing refractory pouring materials and dry and wet injection construction applications.

(4) oxide combined with silicon carbide products (ceramic kiln tools, flame insulation plate, etc.).

(5) High temperature type calcium silicate lightweight insulation material.

(6) Electric porcelain kiln with corundum mullite push plate.

(7) High temperature wear-resistant materials and products.

(8) Corundum and ceramic products.

(9) Cylon combination products.

At present, in addition to the general use of pouring refractories, in the electric melt and sintered refractories have also been a large number of applications.

3 a new type of wall materials, finishes materials:

(1) Polymer mortar, thermal insulation mortar, interface agent for wall insulation.

(2) Cement-based polymer waterproof material.

(3) Light aggregate insulation energy-saving concrete and products.

(4) internal and external wall construction with putty powder processing.

4. Other uses:

(1) Silicate brick raw materials.

(2) Production of water glass. (3) to be used as a reinforcing material for organic compounds. Because its composition is similar to that of silica produced by gas phase method.

It can be used in rubber, resin, paint, paint, not full polyester and other polymer materials used as filling and reinforcement materials.
(4) Fertilizer industry used as anti-agglomeration agent.

Effect

 

Silica ash can fill the pores between cement particles, at the same time with hydration products to produce gel, and alkaline material magnesium oxide reaction to produce gel.

In cement-based concrete, mortar and refractory castable, the appropriate amount of silica ash can play the following role:

1, significantly improve the pressure resistance, anti-folding, anti-seepage, anti-corrosion, impact resistance and wear resistance.

2, with water retention, prevention of segregation, drainage, greatly reduce the role of concrete pump resistance. 3, significantly extend the service life of concrete.

Especially in the harsh environment such as chlorine salt pollution erosion, sulfate erosion and high humidity, the durability of concrete can be increased one or even several times.

4, greatly reduce the injection of concrete and pouring material floor ash, improve the thickness of a single spray layer.

5, is a necessary component of high-strength concrete, has C150 concrete engineering applications.

6, with about 5 times times the effect of cement, in ordinary concrete and low cement castable application can reduce costs. Improve durability.

7, effectively prevent the occurrence of concrete alkali aggregate reaction. 8, improve the density of pouring refractories.
When coexisting with Al2O3, it is easier to generate mullite facies, so that its high temperature strength, anti-thermal vibration enhancement.
