Common knowledge of coating: reflectivity determines heat insulation efficiency

Core tip: the design principle of thermal insulation coating and thermal insulation paint is that when the ratio of the energy reflected by the surface of the object and the total energy projected by the sunlight into the object is the thermal reflectance, the higher the reflectance, the more the heat of the sun will be reflected away, and the object surface will not be overheated by the sun Reflective heat insulation coating and heat insulation paint are made by selecting appropriate resin, metal or metal oxide pigments and fillers and production process to produce high reflective coating reflecting solar heat, so as to achieve the purpose of heat insulation Prevent heat from passing through by reflecting part of the light and heat 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: the design principle of thermal insulation paint and thermal insulation paint is that when the ratio of the energy reflected by the surface of the object and the total energy projected by the sunlight into the object is the thermal reflectance, the higher the reflectance, the more the heat of the sun will be reflected away, and the object surface will not be overheated by the sun Reflective heat insulation coating and heat insulation paint are made by selecting appropriate resin, metal or metal oxide pigments and fillers and production process to produce high reflective coating reflecting solar heat, so as to achieve the purpose of heat insulation By reflecting part of the light and heat out, the heat is prevented from being transmitted to the room through the coating, causing the indoor temperature to rise The fact is that in 2014, Beijing Zhisheng Weihua Chemical Co., Ltd carried out the third technical upgrading and improvement on the reflective heat insulation coating according to the user's feedback on the use effect for many years The upgraded reflective heat insulation coating is more suitable for the reflection of solar heat in summer In 2012, new inorganic materials such as carbon nanotubes, carbides and nitrides were added to the zs-221 reflective thermal insulation coating, which was improved for the second time New materials such as carbon nanotubes, carbides and nitrides have strong electromagnetic wave shielding and aging resistance After adding these materials to the thermal insulation coating, a strong infrared shielding layer can be formed, and the high electromagnetic wave emitted by these materials is being coated The infrared shielding layer is formed on the surface of the material When the infrared ray does not reach the thermal insulation coating, the infrared shielding layer will emit electromagnetic shielding layer, which can effectively shield a large number of infrared rays in the sunlight from the opposite direction and reduce the contact of the infrared rays of the sunlight with the sunscreen and thermal insulation coating Because the infrared part of the sunlight accounts for 55% of the total heat of the sun, the coating will affect the sun Z The sunscreen, heat insulation and temperature reduction performance of S is improved by more than 20% The heat insulation and temperature reduction performance is based on the original temperature and heat insulation, and then the temperature and heat insulation are reduced by more than 5 ℃ In 2014, zs-221 reflective and thermal insulation coating improved the directional arrangement of reflective materials and radiation materials and the floating reflection technology of materials The reflectivity of zs-221 reflective sunscreen and thermal insulation coating can reach 92%, the solar reflectance can reach 0.88, the hemispherical emissivity can reach 0.89, and the reflection temperature of high elevation can be reduced In the hot summer, under the direct sunlight, the total heat insulation and cooling can reach more than 27 degrees Celsius Even in rainy and cloudy days, it can cool down to over 6 degrees, adding new inorganic aging materials, increasing weathering resistance and aging resistance by 30% Zhisheng brand sun protection coating can reach 25 years, and the coating is waterborne, environmental protection, energy saving and the world's leading technology The national standards for reflective and thermal insulation coatings are GB / t25261-2010 reflective and thermal insulation coatings for buildings, JG / t235-2008 reflective and thermal insulation coatings for buildings, JC / t1040-2007 thermal reflective and thermal insulation coatings for external surfaces of buildings, gjb1670-1993gf-i specification for thermal reflective coatings The thermal reflectance of thermal insulation coatings is mentioned on the inside and the solar thermal reflectance is the thermal reflectance of thermal insulation coatings and thermal insulation coatings The key 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,
