Paint filler (which improves the weather resistance of the coating).

In fact, it is not much different from ordinary sand. It's just cleaner.

The composition of quartz sand is:

SiO2, colorless transparent crystal. In fact, due to the small particle size and reflection, the purchased quartz sand looks white.

Just like the table salt we see is also white.

The main component of quartz sand is quartz, with a density of grams per square centimeter, a hardness of 7 on the Mohs scale, and a crystalline system of 60,000 crystals, with a white, blue-gray, gray-white appearance, etc. It is mainly used in glass products, foundry industry, metallurgical industry, ceramic uranium surface, refractory materials, cement industry, chemical industry, etc.

The chemical formula SiO2, also known as silica.

Quartz powder is produced after deep processing of quartz sand.

Quartz sand is a quartz particle made by crushing quartz stone. Quartz is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral, and its main mineral component is SiO2. The color of quartz sand is milky white, or colorless translucent, with a hardness of 7 on the Mohs scale.

Brittle and non-cleavage, shell-like fracture, grease luster, density, bulk density (1-20 mesh, 20-200 mesh, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750.

Quartz (chemical composition SiO2) is the main component that makes up the earth's crust. Some of them exist in the state of silicate compounds, constituting various mineral rocks (such as kaolinite Al2O3·2SiO2·2H2O). The other part exists in an independent state, becoming a separate SiO2-containing mineral entity, mainly vein quartz and quartzite, referred to as quartz ore.

Quartz sand is a powder of various particle specifications that is crushed and processed by these individual quartz ores in a stone powder factory, which can be used in glass, ceramics and refractories, casting, metallurgy, chemical and other industries.

Quartz sand is a quartz particle made by crushing quartz stone. A non-metallic mineral is a hard, wear-resistant, chemically stable silicate mineral. The color is milky white, or colorless translucent, and the Mohs scale is 7.

Technical characteristics of quartz sand filtersThe quartz sand filter material layer is thicker, the filter tank is deeper, and the civil construction cost is higher. The filtration efficiency is high, the filtration effect is better, there is no need to stop the backwashing, and the operating cost is low. The head loss is high, and it is generally necessary to set up a secondary lifting pump room, which increases the operating cost.

The activated sand filter can flexibly increase or decrease the number of filters according to the change of water volume, and is mainly suitable for small-scale sewage treatment plants.

The activated sand filter is a continuous filtration equipment integrating flocculation, clarification and filtration, which is widely used in the fields of drinking water, industrial water, advanced sewage treatment and reclaimed water reuse treatment. The system adopts the principle of upflow flow bed filtration and a single homogeneous filter material, the filtration and sand washing are carried out at the same time, and can run continuously and automatically for 24 hours, and the ingenious sand lifting and sand washing structure replaces the traditional high-power backwashing system, and the energy consumption is extremely low.

1. The hardness is different.

The hardness of ordinary sand simply cannot be compared to quartz sand.

hardness comparison. 2. The silica content is different.

The difference between quartz sand and ordinary sand mainly lies in the silica content, in addition, quartz has high fire resistance, and generally quartz sand is used for casting, and the high temperature resistance is 1750 degrees, so this is also an important aspect of the difference between quartz sand and ordinary sand.

3. The purity is different.

Quartz sand is a sand grain with high purity, mainly silica, which contains a small amount of iron minerals, quartz sand is processed by special processes such as natural quartz stone mineral crushing, selection, magnetic separation, gravity separation, etc. And ordinary sand does not have such a high purity.

4. Different uses.

Because ordinary sand has a corrosive effect on metals and buildings, ordinary sand does not dare to be used in construction, but sea sand is also widely used, and there is a great demand for sea sand in the market.

5. The ingredients are different.

In addition to silica particles, ordinary sand has a large number of impurities of other oxide minerals, such as feldspar, etc., and the silica content is very low. The quartz sand is basically relatively pure silica, generally the silica content is high in or even above purity, the processing cost is low, easy to purify and manufacture, all the sand contains quartz, whether it can be made of glass depends on the content of quartz.

Hey. My family makes quartz sand!

The biggest difference between the sand of quartz sand should be the content of silicon, quartz sand has a high silicon content, while the sand has too many impurities. Although I don't know how to make glass, my glass-making customers have mentioned that they require silicon content. So sand can't make glass!

<> a silicate mineral. The main component of quartz sand is SiO2, which is milky white or colorless translucent, and is a chemically stable, wear-resistant and hard silicate mineral. Its application in the industry is still very extensive, in the construction industry, mainly artificial marble, concrete, cementitious materials, road construction materials, etc., in the chemical industry, the main group is the filling of sulfuric acid tower, silicon compounds and water glass collapse raw material limb source, in the glass industry, is the main raw material of glass products, instruments, in rubber, coatings, plastic industry, are used as fillers.

Quartz sand is a quartz particle made by crushing quartz stone. Quartz sand has the characteristics of hard and wear-resistant, and is an important industrial mineral raw material, quartz sand is mainly used in glass, casting, plastic, rubber and other industries. Quartz sand is mainly divided into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused silica sand and silica powder.

Ordinary quartz sand uses natural quartz ore, and the use cycle is relatively long. The refined quartz sand is made of high-quality natural quartz sand, the high-purity quartz sand is made of high-quality natural quartz stone, the appearance of fused silica sand is colorless and transparent block, and the appearance of silica powder is gray or gray-white powder.

4. Common specifications are: mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh.

5. Quartz sand is a colorless, transparent variant of quartz, which the Greeks called "krystallos", which means "white ice", and they were convinced that quartz was durable and strong ice. The ancient Chinese believed that holding cold crystals in their mouths would quench their thirst. Quartz sandstone is a consolidated clastic rock, quartz clastic content of more than 95%, sensitive to a variety of magmatic rocks, sedimentary rocks and metamorphic rocks, less heavy minerals, associated minerals for feldspar, mica and clay minerals.

Quartzite is divided into two types: sedimentary origin and metamorphic origin, the former has no obvious boundary between detrital particles and cementation, and the latter refers to quartzite ore with deep metamorphism and pure quality. Vein quartz is formed by hydrothermal action and is almost entirely composed of quartz, dense and massive structure. The mineral content in quartz sand varies greatly, mainly quartz, followed by feldspar, mica, cuttings, heavy minerals, clay minerals, etc.
