3 All perlite is a mineral formed by silicon-aluminum volcanic rock, named for its white pearl-like spherical shape. The water content of siliceous volcanic rock is 2% 5%, and when it is crushed and heated to about 1000, it expands to form expanded perlite, which has a small bulk density of 50 180 kg m3. This mineral has a closed cell-like structure.

The main components of perlite are massive, porous, pumice-like perlite, containing a small amount of porphyry crystals, microcrystals of feldspar and various forms of rudimentary crystals, cryptocrystalline minerals, amphibole and other arc-shaped cracks, the fracture is uneven, pearl luster, after weathering, it is grease luster, and the streaks are white.

The color is mostly yellow and white, flesh red, dark green, gray, brown, black and gray, among which gray-white - light gray is the main, the appearance of the fracture is uneven, shell-like, lobe-like, streaked white, in fact, different perlite characteristic morphology, the same kind of perlite, because of the different formation conditions, due to the different internal structure, composition, etc., there are often other characteristics may also appear in different forms is the sign of identifying perlite, but also the basis for analyzing the origin of perlite.

The morphology of crystalline perlite is mainly studied by monomers and aggregates. Therefore, the morphology of perlite is not only. For solid amorphous quasi-(or similar) perlite, there is only a single perlite monomer of aggregate perlite, that is, a single crystal of perlite.

The morphology of perlite monomer mainly includes two aspects: the crystallization habit of perlite crystal (embodied in the crystal shape) and the crystal plane pattern.

Let Zhang ** see for yourself.

What is Perlite? How much do you know?

Perlite is an acidic volcanic glass lava. Brittle. It has a pearly luster and oily luster.

There are special arc cracks. Hardness, density. The expansion factor can reach more than 7 30 times, and the refractory degree is as high as 1300 1380.

After crushing, screening, preheating and roasting, it becomes a porous granular material--- expanded perlite, with which it can be made into perlite products with various beginnings and properties, with light weight, low thermal conductivity, strong sound absorption, non-corrosion, non-combustion, acid and alkali resistance, non-toxic and tasteless, etc., it is a high-efficiency and ultra-light thermal insulation, heat insulation, sound insulation, decorative materials, widely used in metallurgy, petroleum, chemical industry, electric power, construction and national defense industries, and can also be used for casting, soil improvement, detergent, Model filler, paint texture, etc.

Perlite is a vitreous rock formed by the rapid cooling of acidic molten agglomerates from volcanic eruptions, and is named for its pearl fissure structure. Perlite mines include perlite, obsidian, and turpentine. The difference between the three is that perstone has arc-shaped cracks formed by condensation, called perlite structure, and the water content is 2 6%; The pine resin rock has the unique turbin luster of Hetang, with a water content of 6 10%; Obsidian has a vitreous luster and shell-like fractures, and the water content is generally less than 2%.

Perlite is a commonly used building insulation material in the construction industry, and is often used in exterior wall insulation. Dry perlite has strong water absorption, easy to seepage and weight gain, and the outer layer needs to be made with a layer of waterproof coating when it is usually used for exterior wall insulation.

Many people don't know what perlite is, but perlite is a vitreous rock that appears after a volcanic eruption that undergoes a sharp low temperature. It has the ability to effectively absorb water, improve soil and absorb pores, and is mostly used as garden soil. At the same time, perlite also has the disadvantage of being easy to pulverize and endangering human health after smoking.

After the volcanic eruption, the acidic lava undergoes a rapid transformation of high temperature and low temperature, and the vitreous rock formed is what we often call perlite. Perlite is named after the pearly fracture structure of this rock, which is the arc-shaped crack formed by rapid condensation on the rock.

1. Effective water absorption

The arc-shaped cracks of perlite make it have a strong ability to absorb water, and can generally absorb more than 2 or 3 times more water than itself. Therefore, perlite is usually mixed into the soil where plants are grown, so that the soil's ability to absorb and drain water is greatly enhanced, and the plant roots rot are prevented from standing in the pot.

2. Improve the soil

The special structure of perlite can also make it improve the soil, prevent soil compaction due to long-term accumulation or overwatering, and make the soil loose and porous. Loose soil allows plants to take deeper roots, prevents lodging, and allows for better dilution and control of fertilizer concentration.

3. Porous adsorption

The pearl fissure structure of perlite makes it have a good porous adsorption capacity, and it can be well diluted for pesticides and herbicides sprayed into the soil to prevent plants from being poisoned due to excessive concentration. At the same time, perlite can also be used as a carrier of medicinal liquid, effectively preventing pests and diseases from threatening the health of plants.

1. Easy to chalify

In addition to the above benefits, the many pores of perlite also make the perlite more buoyant, and it is easy to float on the water surface after watering. And the perlite texture is light, it may run away when it is blown by the wind, and it is easy to be powdered due to the wind and sun.

2. Harmful to health

The particles of perlite are very small, they are small round white particles, if people do not pay attention to inhaling perlite into the body, it will cause the nostrils and respiratory tract to be blocked by the fine particles of perlite, so that the problem of breathing difficulties occurs, causing harm to people's health.

Introduction to Perlite.

Perlite is a vitreous rock formed by the rapid cooling of acidic lava from volcanic eruptions, and is so named for its unique pearl-like fissure structure.

Perlite composition.

Perlite contains chemical elements such as ferrosilicon, which is chemically stable and has a neutral pH.

Perlite features.

Merit. First, perlite has a very strong ability to absorb water, which can reach two to three times its own; Second, perlite can regulate soil compaction, effectively prevent crop lodging, and control fertilizer efficiency and fertility; The porous adsorption of perstone can be used as a diluent and carrier for pesticides and herbicides in agriculture.

Shortcoming. First of all, perlite is easy to chalver. After watering, it will float on the soil surface and be easily blown away by the wind; Second, perlite is harmful to the human body after inhalation.

Perlite is suitable for plants.

Perlite is used in most plants. The perlite bucket is wide, light and porous, and has a good reputation for air permeability and drainage. It is suitable for growing a variety of plants that require drainage and ventilation media. It is also a good substrate for soilless cultivation and can also be used for cuttings of plants that are not easy to root.

Perlite is a volcanic eruption, acidic lava that has been sharply cooled to form a vitreous rock, so named for its pearl fissure structure. Perlite mines include perlite, obsidian, and turpentine. The difference between the three is that perstone has arc-shaped cracks formed by condensation, called perlite structure, which is mainly used as filler in rubber and plastic products, pigments, paints, inks, synthetic glass, heat-insulating bakelite and some mechanical components and equipment. Perlite expands to become a lightweight, multifunctional new material.

It has the characteristics of light apparent density, low thermal conductivity, good chemical stability, wide range of operating temperatures, small moisture absorption, non-toxic, odorless, fireproof, sound-absorbing, etc., and is widely used in a variety of industrial sectors.

Perlite is a mineral formed by bauxilia volcanic rocks, named for its white pearl-like spherical shape. The water content of siliceous volcanic rock is 2% 5%, and when it is crushed and heated to about 1000, it expands to form expanded perlite, which has a small bulk density of 50 180 kg m3. This mineral has a closed cell-like structure.

Perlite is a vitreous rock formed by the rapid cooling of acidic rocks from volcanic eruptions. It also has similar genesis, occurrence and composition to black rock and pine resinite. After the perlite is calcined at high temperature, the volume rapidly expands by 4-30 times, and countless vitreous closed pores are formed in the rock, which is called expanded perlite.

It has excellent properties such as light weight, thermal insulation, fire resistance, and drug resistance, so it is widely used in construction, energy-saving petroleum, chemical, pharmaceutical, sewage treatment, and agricultural sectors.

1. Application in the construction industry;

2. Expanded perlite is light in weight, sound insulation, heat insulation, good performance, and is widely used in the construction industry (accounting for about 60% of the amount) such as the sound absorption capacity of general perlite concrete is 20 times that of ordinary concrete, and the weight is only 1 10-1 20 of sand, and the mortar prepared with it is 60% lighter than the traditional slurry, so the expanded perlite is widely used as an aggregate for concrete and mortar, which can not only improve the thermal insulation, heat insulation and load-bearing performance of modern buildings, but also reduce the consumption of rigid materials and infrastructure costs.

3. Application in thermal insulation material industry.

Expanded perlite is made into products of various shapes and specifications together with sodium silicate asphalt, cement and other cementitious materials, which are widely used in thermal kilns, pipeline equipment and facilities in chemical, petroleum, electric power, metallurgy, transportation and other industries, and have the functions of heat insulation, steam insulation, heat preservation, radiation protection, waterproof, moisture-proof and so on.

4. Application in filter aid coatings, fillers, etc.

In the fine powder of expanded perlite, many capillaries are formed, and the appearance is colored. It is processed into perlite filter aid, which is lighter than diatomaceous earth and has a large flow rate, which can be used in petroleum, foundry, medicine, food, sewage treatment, etc. In addition, it can also be used as a filler for rubber, enamel, paper and plastic.

The expanded perlite of the filter aid can also be used as a filler for oral impression materials, and the coating prepared by expanded perlite can increase the coverage capacity and the hardness of the coating film, and is mixed with the paint for the ground of the ship to play a lightweight, thermal insulation, anti-corrosion and other functions.

5. In the application of agriculture, the expanded perlite is porous and has adsorption capacity. In agriculture, it can be used as a carrier of fertilizer and water, improve soil, and is often used as a carrier of pesticides and insecticides. In addition, it can also be used as poultry and livestock feed additives and bedding.

6. The role of glass and ceramics.

The waste powder in the production of expanded perlite can save nearly 1 2 soda ash. Used as an ingredient for sanitary ceramics, it can not only reduce the firing temperature, but also make the billet have good molding performance.

7. The role of other aspects.

Perlite is also used to synthesize x-sieve molecular sieve, and is also used instead of emery for polishing marble and picture tubes.
