Features
Wat kaolin refractory is made of alumina, the basis of which is quartz sand. In a special oretermic furnace, melted at a temperature in the range of 1800 degrees. In the melting zone there are three electrodes, while there are only two of them in the place of developing them. The imaging technique is used to smell the material, it is based on the effects of a special steam under the condition of the pressure of about 0.7 MPa. The ejection nozzle ensures the passage of the entire inflating process. Liquid glass, clay or cement can act as binders.
Calin wool is realized in the form of rolls up to 10 meters long, thickness and width are 2 cm and 60 cm, respectively. It has elasticity, thereby ensuring a dense adjacent to any design. Today, manufacturers try to improve the material by adding additional components, for example, yttrium oxide. Due to this, the stability of the fibers is improved and the possibilities of use are expanding.
Fire resistant materials
It is made from the mineral base and are distinguished by resistance to the effects of high temperatures, while their characteristics remain at the same level. They are indispensable in the metallurgical industry to conduct distillation, evaporating and other processes, the creation of high-temperature mechanisms (motors, reactors) and parts for them. After using refractories are sent for processing.
Most often, products of this species have a rectangular shape and a small mass, due to which they are optimally suitable for various lining. Currently, there is a decrease in the production of simple refractories, since increasing attention is paid to the production of special solutions and concrete, resistant to high temperatures.
Methods of manufacture

The full functioning of the fireplace, as a rule, depends not only on what type of heating device you will pick up for your cozy home, but also on the accuracy of the installation of thermal insulation and correctly selected thermal insulation materials. Among other things, well-performed thermal insulation is considered a reliable warranty of fire safety, which is why the price of such materials and the procedure of their laying often exceeds the cost of the fireplace itself.
It must be said that such an indicator is considered one of the most significant characteristics of insulating materials. Moreover, during the heating of foci, the thermal insulation material behaves as follows: the lower the thermal conductivity, the greater the ability to interfere with heat transmission. Thus, it is the thermal conductivity that is considered one of the most significant criteria for the acquisition of thermal insulation materials.

Basalt wool, which is still called "stone", is characterized by a fibrous structure. For the manufacture of material used basalt, metallurgical slags, as well as mixtures thereof.
An important component of the material is the binder substance (this may be bitumen, synthetic substances and bentonite clay). Such substances help in fastening wool fibers with each other. Basalt wool on the market is produced in the form of plates ("mats"), rolls ("cylinders") or in bags. In the latter case, the binder is not used.
The main advantage of basalt wool's main characteristics is excellent thermal resistance, since the material does not ignore and does not melt, it is characterized by stability to rot, good water repellent features. If you allocate the minuses of stone wool, it should be said separately that if the temperature reaches the six hundred - the seven of degrees Celsius, the binding element in the wool structure will be collapsed, as a result of which the properties of the thermal insulation material itself will occur. Among other things, the minuses include a high price category of wool, the presence of seams in the installation zones, dust dust during the assembly process and a rather large paroque ability, and this is a limitation of the material utilization.
Watts from Basalt are widely used in different areas, but mainly it is used to build buildings, it is a thermal insulation of pipelines, technical devices, floating floors, conducting smoking systems through ceiling floors, heat insulation of ceilings and walls, assembling warmed sandwiches and sandwich-panels .
Kaolin Vata.
Kaolin wool, it is still referred to as ceramic, is considered an alternative glasswater. Kaolin wool is the thermal insulation type of material that is made of technical alumina. Currently, ceramic wool is produced in the form of rolls, plates and comedy wool. Components of ceramic wool fibers combine with each other with all sorts of binders: refractory clay, hydro-grade cement, silicate glass, silicon organic substances.
The material is highly popular with buyers due to increased refractory, as it can withstand the temperature indicators from a thousand hundred to a thousand two hundred and fifty degrees Celsius, provided that zirconium or alumina fibers will be used for production, their temperature criterion may increase to a thousand four hundred - Thousands of six hundred degrees Celsius. In addition to the listed indicators, it is worth noting the low thermal conductivity, high sound insulation, waterproof, electrical insulation, and the fiber density is one hundred and thirty kilograms per cubic meter. The material is blown out, which is already related to its minuses, it is environmentally safe.
Kaolin-type wool is used in different directions, it can be the production of plates, sealing inserts; Reliable isolation of buildings, ceilings, use as a specialized lining of foci, for the release of insulated chimneys, isolation of chimneys through wooden floors, as well as the Bedmark thermal insulation material.
Superisole is a lightweight material with a porous structure, characterized by excellent insulation indicators. Such high marks it turns out to be achieved due to the presence of small pores inside the superimol, which help to withstand the temperature within two hundred and thousands of one hundred degrees Celsius. The substance is made on the basis of calcium silicate.It is worth noting that despite the rather high price category, the material is in demand from Russian buyers. Superisole is distinguished by its ease, thus one sheet of material weighs only eight kilograms, among other things, it is environmentally friendly and tight. At the same time, buying superizol, you do not have to forget that he poorly absorbs moisture, but some foreign companies are already represented with increased moisture protection.
Superisole is perfect for thermal insulation of different options for foci. But it is usually used for the insulation of ceiling overlaps, carrying out smoking systems through the roof of the building, as well as to install the fire cutting of fireplaces, the installation of foci of increased power and the manufacture of fireplace boxes of the decorative sample. It should be noted that the material is today considered one of the most suitable for the construction of foci by the option, which allows it to be used in the most difficult places of compound.
Plates from vermiculite are produced using special minerals from a group of mica, characterized by their layered structure, as well as with the help of binders such as bitumen and silicate glass.Vermiculitic plates are distinguished by their environmental cleanliness, since they do not contain organic fibers in their array, asbestos, therefore, they are characterized by an increased level of heat resistance and thermal insulation, that is, they can withstand the temperature from fifty to a thousand two hundred degrees. The material has a long utilization time, it is simply cut and easily glued.
Summing up, you can confidently say that the material is well suited for isolation. However, due to the fact that the plates are highly density, it does not fit for the construction of light designs.
In addition, it should be noted that the vermiculitis refers to fragile substances, so with inattentively breaking and crumbs. Typically, the plates are used for refractory lining and thermal insulation of foci and chimney systems, as well as increasing the refractory facilities.
The mass of mineral wool insulation is allocated silica wool SuperSil. The characteristics of this thermal insulator are quite high, they include the ecological purity of the material that does not highlight harmful substances into the atmosphere of the building during heating. SuperSil has increased fireproof, reaching thousands of two hundred degrees, excellent heat and sound insulation. Wat does not have carcinogens and fibrous inclusions.
Material for sale is available in the form of mats and is used for isolation of chimneys, wooden walls, fireplace floors, air ducts, outlet pipes and thermal insulation boxes.
Minerito Plates are produced on the basis of a special substance of fibrocement, a fibrous substance, as well as a lime filler. The material has a resistant surface, as well as good density. The plates of this sample do not absorb moisture, do not rot, are characterized by high indicators of sound insulation, strength and thermal insulation. The heat resistance of the substance varies within eighty - thousands of a hundred degrees Celsius. Plates are simply easily decorated and serviced, when heated does not allocate harmful volatile substances.
Since GVL sheets can be painted, boxes are often performed from this material. Among other things, the KNAUF-superlist is used to cover framework devices, as fire protection of installations, partitions, wood insulation, wood and walls in the approachable zone.

Today, the Russian market presents a huge amount. However, not all of them are the same and able to withstand harsh climatic conditions and reliably protect against the heat loss of the building, communications. Statistical data from the construction complex of Russia showed that the main type of insulation used in Russia are mineral wool products to which are mineral, kaolin, quartz, graphite wool. All of them have an increased temperature resistance, their market share is a little more than 65%, the remaining 35% are different types of foams that are significantly inferior to mineral wool.
Minvata.
Mineral wool is a thermal insulation material consisting of the thinnest glass fibers obtained by spraying the liquid melt of the mixture from metallurgical slags, rocks or other silicate materials. Depending on the outgoing raw materials, the mineral wool is divided into: stone WatWhich made from mineral rocks (sedimentary rocks: clay, limestone, dolomites, mergels and lowered: granites, sinites, pebmatites, pemps) and slag cottonMade from metallurgical slags - domain, combustion and Marten slags, as well as slags of non-ferrous metallurgy.
The thermal insulation properties of mineral wool are determined by the airpasses concluded between the fibers. Mineral wool It is manufactured by blowing and centrifugal methods. The basis of the blowing methods is the use of the kinetic energy of steam, compressed air or gas coming out of the nozzle and occurs on its way a stream of silicate melt, as a result of which the latter is divided into drops, stretching first into cylindrick, which is then narrowing and forms two pear-like bodies associated thread. Pear-shaped bodies decrease and turn into fibers. The centrifugal method is based on the use of the centrifugal force of the rotating disk, which falls the stream of silicate melt.
There is also the most "tricky" method of obtaining mineral wool - centrifugal filter-blowing. It provides a complete absence of non-binding inclusions (so-called "kolkov"), as well as a small diameter of wool fibers. The properties of mineral wool: with an increase in the content of silica in the mineral wad, the temperature of its softening and temperature resistance increases. Alumina increases the chemical and biological durability of the wool, iron oxide reduces temperature resistance, increases the corrosion of the wool. The coefficient of thermal conductivity depends on the average thickness of the fibers, bulk weight and porosity. The optimal porosity is 90%. The thickness of the fiber can vary from 2 to 40 microns.
Glasswater
Glass Vata. This is a thermal insulation material consisting of randomly located flexible glass fibers obtained by pulling out of molten glass. Raw materials for receipt glasswater Serves glass or glass industries.
Manufactured glasswater In two ways, the blowing and method of continuous pulling (filler-blowing). The technological process of producing glass fiber on the blowing method is similar to the blowing method for producing mineral wool. Glass fiber has a thickness of 4 to 30 microns, the fiber length is 120-200 mm. The way continuous pulling looks like this. The glass charge is loaded into the bathroom furnace (T \u003d 1500C), under the influence of the temperature melted over the surface and flows the thin layer in the homogenization zone where it becomes more uniform.
The melt leaks through a special plate, which has holes (moving) with a diameter of 0.1 mm. A thread is pulled from the flowing jeting of the melt with the help of a rapidly rotating drum. The method of continuous pulling gives fiber without "kolkov", uniform thickness and high quality. Fiberglass strength depends on its thickness. The fiber thicker, the more fragile. Fiber fragility causes its rapid destruction during vibration. That is, the optimal thickness of the fiber must be 15 μm and less.
More advanced fiberglass production technologies allow to obtain an average thickness - 6 μm (that is, the fiber is practically not irritating the skin and mucous membranes of the respiratory tract). The technological process of producing glass wool isover consists of the following steps. Raw materials (used glass, sand, soda, limestone) melted in the furnace (T \u003d 1400C and higher); After that, the molten mass flows into the fiber-forming agent, which is a spinning centrifuge, where glass breaks on the fibers.
Between themselves, the fibers of the glass wool bind with the help of a binder (it is mixed in the form of an aerosol with fiberglass during the fiber formation process). Products impregnated with resin fall on heat treatment (T \u003d 250C), which gives the required insulating material the required rigidity. The coefficient of thermal conductivity of fiberglass fluctuates (0.029-0.040 W / MK), temperature resistance + 450c, frost resistance (Stock photota freezing and thawing) -25c. Glasswater is resistant to the effects of acid and heat meter industry and thermal conductivity of glass gamble differs from minvati, in which a smaller average density, less temperature resistance. It is used for the thermal insulation of building structures, as well as in technical insulation (pipelines, industrial equipment), as well as refrigerators and vehicles.
Kaolin Vata.
Kaolin wool and products based on it refer to refractory (high-temperature isolation, use temperature T \u003d 1100-1250C). The raw material for its production is a technical alumina, containing 99% aluminum oxide, and pure quartz sand. The melt is obtained in a five-electrophole oretermic furnace (melting point of 1750 ° C). The workspace of the furnace consists of zones of melting and generation. The melting area is equipped with three graphitized electrodes, the development zone is two. The melt jet is inflated by ferry under a pressure of 0.6-0.8 MPa with the help of an ejection nozzle.
Liquid glass, alumina cement, refractory clays, silicon-organic binder are used as bindings. The average density of kaolin wool 80 kg / m3. It is resistant to vibration, inert to water, water pair, oils and acids, has high electrical insulating properties, which practically do not change with an increase in temperature to 700-800s, is not wetted by liquid metals. Kaolin Vata is produced in rolls and in the form of products of various shapes (plates, shells, segments, etc.). Kaolin Vata. It is manufactured in the form of coma wool and various products. Scope - various industries.
