ABSTRACT
The article describes innovative technologies for the use of materials with heat preservation properties, the results of experimental studies on the analysis and improvement of existing methods for determining thermal conductivity. On uneven surfaces, methods of applying heat-protective coatings, effective use of heat are perfectly illuminated.
Keywords: modern thermal insulation coatings, energy efficiency, thermal conductivity, microsphere, requirements for thermal insulation coatings, advantages and applications of liquid thermal insulation coatings.
Adequate use of heat while reducing energy consumption is one of the most pressing issues in the world. One of the most important tasks to be addressed in the construction of modern buildings and structures is the efficient use of heat in the delivery of hot water from the heat sources (TPP) to the population. The advent of new heat-insulating materials has solved many problems related to energy efficiency in buildings (TPPs). Efficient use of thermal insulation coating has helped to optimize construction and heating costs, increase the service life of buildings, improve microbiological performance, create and maintain a favorable microclimate inside the building.
So what is heat? Thermal conductivity? What are the advantages of a heat-insulating coating? Heat-insulating coating (insulation) is a material used in residential and industrial buildings, heating units and pipelines to reduce heat loss to the environment.
Heating materials have a porous structure and low density (more than 700 kg / m ) as well as heat conductivity (maximum 0.30 W / (m 0C)). They are function according to 4th grade divided into
A 0.07 Vt / (m-°S)
B 0.07 -0.12 Vt / (m-°S)
V 0.12 -0,18 Vt / (m-°S)
G 0.18 -0.30 Vt / (m-°S)

Basic raw of the item type according to heat insulation The use of materials mineral ( inorganic ) or organic , q to the field according to insulation - construction (relative cold surfaces for ) and insulation - mounting (cold and Hot surfaces for) shape and external appearance on heat insulation materials pieces to be prepared solid (slab, shell, segment, brick, cylinder) and flexible (fabric, cord), soft and friable materials (cotton, perlite, sand, vermiculite) divided into.
Structure on heat isolation materials fibrous (mineral cotton, fiberglass (granular) perlite, vermiculite), porous (porous from concrete prepared materials, foam glass) materials classified.
Most heat insulation materials high degree porous to be as a result sound swallow ability has that is noise with fight for from them acoustic materials can also be used as opportunity gives Sound winner materials high degree sound swallow coefficient has to be need (of the material partially swallowed sound his energy to the surface falling all energy ratio ) - 1000 Gts frequency - less than 0.4 lack of need as well time pass with his acoustic properties unchanged without and engineering aesthetics and hygiene requirements mos arrival need.
Heat and sound insulation for following materials and items functional Produced: mineral cotton and his based on The material is based on fiberglass materials, foam glass, thermoset picture 2 (inflated slag), expanded clay, porous from ceramics made pieces, inflated perlite and vermiculite, asbestos, diatomite and trepel based on items, light and special light concretes, technical all kinds of cardboard species, reeds plate and straw board, wood plates and so on materials, foam and porous plates, solid and elastic, three layered plastics and sotoplasts, porous and tola based on wrapping materials, peat and plugged plates, felt, hemp, mok and so on materials in size applied. Them new very promising density kam which was and high mechanical properties has which was non-flammable and biostability has which was technological materials that is foam metal with exchange possible .
Heat and sound insulation materials in transport application this wrapper and lifter structures (walls, partitions cover, column, sea and river of ships hulls, wagons bodies and so on), mass reduces, required heat conditions minimal energy cost did without to create (buildings, refrigerators and isothermal containers, wagons, vans, refrigerators and others), basic construction of materials need reduction ( in metals, reinforced
