High-temperature heat insulation for furnaces and stones

The Russian Federation of the market of ovens and stones is selling new products and materials. The leather vyrobnik is more comfortable than the carpet on itself, it is more expensive, but the very product itself is the most beautiful, unique and effective. The sellers, who do not have any practical advice, give jagged information about the sales trainings for the detailed nutrition. Spozhivachev, as long as it’s all the same, he didn’t turn to the fakhivts, he had only a little strength and an hour to bring up all the nuances.

The most important aspect in the operation of stones and ovens is the safety. Here it’s like once that vipadok, if bazhanya sparing or banal nondibility at once, without needlessness, can lead to a great bidi. The main design element, which is a guarantee for safety, is a high-temperature thermal insulation.

Theoretically, it is possible to perform editing with your own hands, a little bit more can be done about human life, more beautifully to trust the robot to fahivtsy. On the market of awakening services of the lackluster companies, those who are well aware of such a service, protest to the choice of the officer, so it goes with great strictness - the company has been guilty of being on the market for a long time and the mother has been reputed. It’s not easy to get migrant workers and shabashniks, there’s no one to feed them.

Vimogi to heat-insulating materials

For his sutta there is a stone and a fire with an open firebox and a dimokhod, without decorations. There are no other design features, because they do not seem to be out of the question, because they go before the installation and are equipped with one and the same. Thermal insulation, apparently, it should be shown near the firebox and for the air flow and is guilty of coming to the advancing vimogs:

• low heat conductivity
• ecology
• visoka fire
• good fortune
• Maximum permissible temperature for heating

Reinsurance of the authorities' materials were guilty of taking care of the general responsibility by extending the term of exploitation.

Classification behind the warehouse

High-temperature insulation materials are subdivided into the following types:

1. Stamping and filling: zirconium oxide, quartz sand, versatile mortars, kaolin. Wickedness, in the main, in industry, labor at work
2. Fibrous insulators: wadding, wool, felt, according to the essence of its є mineral wadding and produced. May be the lowest thermal conductivity factor, resistant to thermal shocks, protects against mechanical failures
3. Solid materials: fireproof cardboard, chamotte cegla, virobi from fireproof ceramics plates. Preserve the first form and can be mechanically adjusted

At the bottom of the furnaces of furnaces and stones, as well as the metal and asbestos-cement flow itself, you can insulate yourself with mineral wool. Tseglyan dimokhodi insulate with solid materials from the lining, or just vikonuyut plaster in three balls.

Inspection of the market of heat-insulating materials

Establishments of admirable prices and high availability є the most popular product in the field of storage. Warehouse - 100% Kamyan (gabro-basalt) cotton wool. Two types are released: without coating and with aluminum foil from one side. The maximum allowable temperature from the side of the foil is + 500 ° C, from the side of the wool + 750 ° C. The size of the plate is 1000 * 600 * 30 mm, the thickness is 100 kg / m3.

The thermal conductivity coefficient at + 300 ° C should be 0.088 W / m * K. The option without foil is non-flammable, with foil, flammability class G1. When the material is vibrating, it is even more important to increase the temperature of the furnace, so that when overheating the foil can stick out and an unpleasant odor spreads along with the micro-particles of cotton wool. The insulator slabs are very dull, so they are mounted in a rigid metal frame.

vermiculite

Natural mineral from a group of hydromicas, sharuvat is the structure of a thread when heated. Vognezakhisnі materіali viroblyayut with a new path of preservation. Most of the furnaces are stagnant in the aviation and automotive industry, as well as in the nuclear energy itself, as well as the gamma-vipromyuvannya. On the market there are material of performances by two virobs:

• Vermix Refractory. Kraina-virobnik - Russia, thermal conductivity coefficient at + 300 ° С - 0.18 W / m * K, plate size 600 * 600 * 30 mm, capacity 300 kg / m3, permissible temperature + 800 ° С. installation, a rigid frame is not required. Minusi is so very present - material is afraid of vologues.
• Skamolex is a vermiculite heat insulator for import from Dania. It is a symbiosis of refractory and decorative panels with different design solutions. Heat conductivity at + 200 ° С to become 0.16 W / m * K, plate size 1000 * 610 * 25 mm, thickness 600 kg / m3, peak temperature + 1100 ° С. having set and forgotten ”, vikoristovuyutsya for the footer of the furnaces. Z minusiv - visoka parti, in the fallowness from the region of the Russian Federation the price of the plate can be 5 times the plate of the same area Vermix Refractory.

Based on calcium strength

The upstream row of the thermo-insulator is calcium silikat - inorganic speech in the form of calcium and metasilicic acid salts. On the market of minimal performances in the offensive viconance:

1. Silca 250km. Import from Nimechchin. Plates with a size of 1000 * 625 * 40 for storing in ovens, stones and dimochannels. The density is 250 kg / m3, the thermal conductivity coefficient is 0.09 W / m * K at + 200 ° C, the temperature is + 1100 ° C. The structure of the plate is not fibrous, it can be an insulator as a lining material, absolutely not for the health of people. In particular, the installation of the metal frame does not shrink. Go for thermal insulation of wood walls in the firebox.
2. Promasil 950 ks - Chergovy goods from Nimechchin with a size of 1000 * 500 * 30 mm and a thickness of 245 kg / m3. When the voltage is 900 ° С, the heat conductivity at + 200 ° С becomes 0.10 W / m * K, it is not necessary to move ahead of the front of the isolator on the other side of the lower part. It is easy to mount without a frame, the virobnik guarantees ecological safety. The material is usually new, practical reports about the first time in the region are few and far-fetched, but the cost is low in terms of analogs.
3. Scamotec 225 is a student of Dania. Slab size 1000 * 610 * 30 mm, thermal conductivity coefficient 0.08 at + 200 ° С, maximum storage temperature +1000 ° С, easy to install without a frame, not very durable for health, provided it is possible to keep the heat insulating and decorative. vognestiykoyu farboy. Behind the charge is in the middle price segment.
4. Isolrath 1000. Country of travel - Austria. Size 1000 * 610 * 30 mm, thickness 240 kg / m3, heat conductivity 0.06 W / m * K at + 200 ° C. Working temperature up to + 900 ° C, the frame for installation is not required. Virobnik is a guarantor of ecology and safety on the basis of many high-quality designs. Lay also until the middle price segment.

Another group of thermal insulators is represented by a single cement-based material. Miner LV to import from Dania. The size of the virob is 1200 * 630 * 9 mm, the thickness is 1150 kg / cubic meter, so that the material to finish is important, but it is thin - to save the living space. The thermal conductivity coefficient is set to 0.25 W / m * K, so that the suttau moves to the previously seen images.

The temperature of consumption of Minerita LV is up to + 150 ° С. Vyhodyach with parameters, it can be used as a supplementary element in the already thermo-insulated top of the stone, either in the oven, or in the highly specialized virobes.

The most important factor, which is responsible for the vibration of heat insulation for furnaces, is the correct setting of the peak temperature. The temperature is stored in the form of a fire, the heating of the furnace and the other parameters, so the value of the key parameter is more beautiful than the parameters.
