Coating classification: paste phase change energy storage thermal insulation putty

Core tips: simple Abstract: paste phase change energy storage and heat insulation putty is made of elastic emulsion as a film-forming material, with Ceramic Hollow Microbeads, shape stabilized phase change materials, heavy calcium and talcum powder as fillers The paste phase change energy storage and heat insulation elastic putty is prepared with the aid of auxiliaries and water Besides having good adhesion strength, elasticity, water resistance, permeability and permeability, it also has phase change energy storage, temperature regulation and temperature control And thermal insulation function, and external wall insulation system has excellent compatibility, matching and synergy Heat insulation mechanism: the temperature control and heat insulation mechanism of paste phase change energy storage heat insulation putty is as follows: In use for external insulation system Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: Introduction: paste phase change energy storage thermal insulation putty is based on elastic emulsion film, ceramics Hollow bead, shaped phase change material, heavy calcium and talcum powder are used as fillers, and paste type phase change energy storage and heat insulation elastic putty is made under the coordination of additives and water, which has not only good bonding strength, elasticity, water resistance, permeability resistance and permeability, but also phase change energy storage, temperature control, heat preservation and insulation functions, and external wall The external insulation system has excellent compatibility, matching and synergism Heat insulation mechanism: the temperature control and heat insulation mechanism of paste phase change energy storage heat insulation putty is as follows: In the elastic putty for external insulation system, add a proper amount of phase change material paraffin In hot season, the temperature of the putty layer rises due to absorption of solar radiation heat and air convection heat transfer When it reaches the melting point of paraffin, the paraffin starts to change from solid state to liquid state At the same time, it absorbs heat energy and stores it, so as to control the rising speed and maximum temperature of the wall temperature (wave peak) value, reduce the heat transmitted to the internal wall; when the temperature drops, the temperature of putty layer will drop accordingly; when the temperature drops to the phase change point of paraffin, paraffin will produce reverse phase change, from liquid to solid, and release the stored heat, so as to slow down the temperature drop rate of putty layer Finally, the peak valley temperature ratio is slightly higher than the same, reducing the high and low temperature The temperature difference can prevent or reduce the temperature change cracks caused by too fast or too large temperature difference in the insulation layer The phase change material plays the role of "peak cutting and valley filling" in the process of temperature change of elastic putty Properties: ① paste phase change energy storage insulation elastic putty is the supporting material of external wall external insulation system, and the putty layer can play an important role in shielding the cracks of protective layer, preventing the cracks of decorative coating, enhancing the effect of heat preservation and insulation, and improving the efficiency of energy conservation (2) the film forming material is composed of cross-linked acrylic emulsion and VAE emulsion When the ratio of 3-4 to 1 is 40%, the physical indexes of putty meet or exceed the JG158-2004 standard, and the elongation of the coating is 187% ③ The paraffin liquid is adsorbed into the micropore of sepiolite to make the phase change material and add it to the putty The paraffin can absorb or release certain phase change potential under isothermal condition, and store and exchange heat with surrounding medium or environment to achieve the effect of heat storage and temperature control When the content of paraffin is 6% - 8%, compared with the same formula putty without paraffin, the wave crest of surface temperature is reduced by 6-7 ℃, the wave trough is increased by 4 ℃, and the wave trough temperature difference is decreased by 10-11 ℃, which has an obvious heat insulation and cooling effect ④ The putty made of light porous material composed of sepiolite powder, wood fiber and ceramic hollow bead has good thermal insulation When the total amount of filler is constant and the content of sepiolite powder and wood fiber is fixed, when the content of ceramic hollow bead is 20%, the thermal conductivity of putty is 0.091 w / (m · K), and the physical and chemical properties are excellent Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
