Chrysotile asbestos GOST 12871-2013 grade A-6-30 TU 5721-003-005-29-994-2015. Used in the production of asbestos technical, asbestos-cement products, thermal insulation. They are used for thermal insulation of furnaces and heating devices, lining of steam boilers. Chrysotile asbestos (other names are asbestos chips, chrysotile asbestos, asbestos chips, asbestite, asbestos) is a natural mountain mineral serpentinite is a raw material for obtaining chrysotile-asbestos material, unique in its properties. Chrysotile asbestos, the so-called asbestos crumb, has excellent applied technological properties. In terms of strength, the material is comparable to the best grades of steel, has low electrical conductivity and very high heat resistance.
Chrysotile asbestos 6-30 (50 kg) chemically inert:
does not dissolve in water.
does not collapse under the influence of oxygen, solar radiation, ozone.
The material is characterized by high fire resistance.
when processing chrysotile, the fiber fluffs up and acquires a high ability to absorb other chemicals
Chrysotile asbestos, asbestos crumb is used for the manufacture of especially important electrical insulating asbestos products and filter cardboards
Asbokroshka is also used in the production of special paronite, electronite, electrical insulating cables and other materials.
Chrysotile asbestos, asbestos crumble, is used as a protection of metal structures from exposure to high temperatures, for thermal insulation of furnaces and heating devices, lining of steam boilers, is used when lining heat pipes and pipelines, for organizing repair and restoration operations of heating mains
Products based on asbestos are used as a heat-resistant heat-insulating material, in the manufacture of industrial equipment, high-strength asbestos-textolites, rubberized fabrics.
Asbestos is a fairly popular building material. Due to its unique properties, it has replaced other even modern analogues from production processes. To this day, it has not been possible to find in nature a more effective replacement for asbestos. And those few synthetic analogues that exist still lose to him in terms of operational capabilities. In addition, the profitability of the extraction of such raw materials is very low. It is developed by open pit mining. Then the collected ore is enriched in factory conditions using a special technology.
In this case, we are talking about the chrysotile type of raw material. This mineral fiber is white in color and does not have a specific odor. There may also be another color of asbestos crumbs:
greenish with a yellow tint;
light gray with a pronounced silky sheen.
The length of the threads, as a rule, is from 5 to 6 millimeters. Although sometimes come across fibers and 15-16 mm.
Kinds
It is customary to classify asbestos crumbs according to the type of fiber structure. Guided by this feature, the material is selected for various technological processes in production. We list these three varieties;
soft asbestos;
semi-rigid material;
hard asbestos.
In addition, raw materials are usually divided into 8 grades. In this case, the length of the fibers is directly taken into account. The first tory varieties are classified as long-staple asbestos. The other 5 varieties, respectively, are called short-fiber (building) material.
Application
Asbestos chrysotile or asbestos crumb finds a fairly wide application. Today, the number of goods where this material is present is more than 3000 items. This is a very large number. At the same time, the industry uses fibers of a certain length. In this case, these are mineral threads with a length of at least 0.5 millimeters. Firstly, this is required by the technology of processing raw materials. And secondly, a product made of such fibers is as safe as possible for human health.
And so, asbokroshka has several "application points". Among them:
industrial production of special, fire-resistant materials;
a component that significantly increases the wear resistance of the modifier;
production of pressure and non-pressure pipes based on asbestos chips;
an additional component when laying a road, asphalt canvas;
an additional component with which you can enhance the anti-friction ability of moving mechanisms;
filler. Here we mean resins, some types of plastics, as well as insulators;
manufacture of complex devices for filtration. Such equipment is in demand primarily in the food and chemical industries. In addition, for these purposes, asbestos is also purchased by the pharmacological industry;
element for the production of batteries and special acid superchargers. It is important to note that all these materials, thanks to asbestos crumbs, increase their resistance to aggressive media (alkalis / acids);
large-scale production of technical/cement/bitumen/molar products.
Characteristics
Chrysotile asbestos (aka asbestos) has excellent performance in most physical and chemical properties. Here are some of these unique features:
very high operating temperatureA. The material is able to operate at a temperature of about 500 degrees Celsius. At the same time, the material does not lose its original structure;
high melting point. It is 1550 degrees. Thus, the asbestos crumb is not at all afraid of long-term, high-temperature heating;
optimum coefficient of friction. It is this, as mentioned above, that makes it possible to use the material in moving mechanisms;
resistance to contact with alkalis. Even direct interaction does not have a destructive effect on asbestos. This made it possible to use raw materials in the chemical industry.
Storage
Asbestos should be in a tight and hermetically sealed package. Only in this way is the preservation of all its operational properties guaranteed. In addition, it is necessary to exclude high humidity in the room where raw materials are stored.
Chrysotile asbestos is the only type of asbestos that is widely used throughout the world. It is the least dangerous, even when compared with cellulose or artificial substitutes, because it is removed from the human lungs faster than all other fibers. And in general, chrysotile asbestos is harmless to the body - from a chemical point of view.
Chrysotile asbestos, like its other "brothers" (dangerous varieties of asbestos), is capable of splitting into the finest fibers, resembling cotton wool fibers. However, unlike natural wool, asbestos fibers do not burn and can withstand very high temperatures.
Chrysotile asbestos, as well as products made from this material, fully retain their performance at temperatures up to +500 degrees Celsius. If the ambient temperature exceeds +700, then asbestos fibers become brittle. Chrysotile asbestos melts at a temperature of +1500 degrees Celsius.
It has good dielectric properties. Purpose: for thermal insulation of furnaces and heating appliances, lining of steam boilers, in the production of asbestos-technical, asbestos-cement products. Products based on asbestos are used as a heat-resistant heat-insulating material, in the manufacture of industrial equipment, high-strength asbestos-textolites, rubberized fabrics. Asbestos is made up of a mixture of fibers of various lengths. Depending on the length of the fiber, it is divided into 8 groups: 0, 1, 2, 3, 4, 5, 6 and 7 - group 0 is the maximum fiber length, the 7th group is the minimum fiber length and is marked with the letter A. Fire and explosion proof.
Asbestos has gained wide popularity due to its availability and good stable qualities. Existing asbestos is strictly divided by texture. So, some of the types of asbestos fibers can be dangerous to human health. These include anthophyllite, crocidolite, amosite, tremolite, and akinilite, which are collectively referred to as amphiboles. They include different types of asbestos, the fibers of which are hard and have hard needles. But there is also such asbestos, which is quite safe for humans - this is chrysotile asbestos, its fibers are soft, and the needles are elastic.
The danger of amphibole asbestos lies in its acid resistance - their structure is such that, settling in the lungs of a person, it is practically not removed from them, which affects the functioning of the respiratory system. Chrysotile asbestos, on the contrary, decomposes very quickly under the action of weak acids and easily leaves the body. Be that as it may, the world is actively arguing about the dangers of this type of asbestos. In particular, proposals were repeatedly made at various international conferences to ban chrysotile asbestos for use. However, while these proposals have remained proposals.
Asbestos has been used in industry for over 100 years. Asbokroshka, of course, is used as a heat-insulating material, as well as for the manufacture of ATI. Asbestos crumble can be combined with such common thermal insulation material as glass wool and is used for thermal insulation of boiler and heating equipment.
Asbokroshka offered for sale is made on the basis of chrysotile asbestos, the use of which is permitted on the territory of the Russian Federation. The main regulatory document regulating the quality of asbestos is GOST 12871-93. The GOST specifies the characteristics and properties, displays the order of labeling, storage and use of this type of product. In particular, GOST 12871-93 defines the sorting order into groups depending on the length of the asbestos fiber. There are eight such groups in total: 0, 1, 2, 3, 4, 5, 6, 7. Asbestos from the zero to the sixth group differs in grades and fractional composition. Asbestos of the seventh group is subdivided into groups according to bulk density. A detailed list of brands and their characteristics can be found in GOST 12871-93 itself. High-quality asbestos should not contain foreign inclusions and should have a moisture content of not more than 3%. When buying asbestos, pay attention to its labeling. High-quality asbestos from reliable manufacturers is marked according to GOST 14192, which reflects such characteristics as the name of the manufacturer, brand, batch number, date fromcooking and other data.
