release date:2015-12-07 Views:7 Back to list
Nano thermal insulation coating literally means the protection of objects, both heat insulation and heat preservation. It is mainly a layer of nano protective film, the main component is nano materials, so that the heat energy of objects containing temperature will not be lost. The components of nano thermal insulation coating are nano zirconia, nano aluminum oxide, nano titanium oxide, nano cerium oxide, and hollow ceramic beads. All nano inorganic components are excellent zirconium nano thermal insulation coating Collection A new type of cooling and heat-insulating coating that integrates reflection, radiation and hollow microbead insulation. The coating can highly reflect a wide range of solar infrared and ultraviolet rays, has a high heat reflectivity, and can automatically radiate and dissipate heat, removing heat from the surface of objects. Radiate into space to lower the temperature of the object. At the same time, hollow microspheres with extremely low thermal conductivity are placed in the paint to isolate the transfer of heat energy. These three major functions ensure that the object painted with the paint cools down and ensures that the internal space of the object can be maintained for a long time. constant temperature state. Principle of action After the above-mentioned nano-alumina, nano-zirconia, nano-cerium oxide, etc. are deposited on the outer surfaces of steel plates, reactors, ceramics, roofs, buildings, etc., nano-aluminum on the surface of various nano-oxide particles Oxygen, zirconium oxide, cerium oxide, etc. have close to atomic size and can reflexively recombine to form nano ceramic bubble shells. Combined with hollow ceramic beads, the heat preservation effect is good. The thermal conductivity effect is /, which has the effect of absorbing and reflecting infrared rays and blocking the transfer of thermal radiation. Double thermal insulation When used indoors in buildings coating, applying a thin layer can effectively enhance the thermal insulation effect. In autumn, the indoor temperature can be increased by ℃, and in summer, the indoor temperature can be reduced by the same amount, thus saving considerable water and electricity costs. Since the coating itself has a long life, applying it to the waterproof layer of buildings can reduce roof repair and replacement costs and solve roof leakage problems. In addition, the coating contains high-tech anti-corrosion ingredients, which can not only eliminate existing corrosion on the metal surface, but also prevent further corrosion on the metal surface. It has strong adhesion with walls, metals, ceramics, cement, wood products and other substrates. It can be applied directly on the surface of the substrate to achieve the purpose of heat insulation. Product functions , Thermal insulation, heat insulation Low thermal conductivity. The bubble shell and hollow ceramic beads are used to block heat conduction and heat insulation in the air, and nano-alumina, nano-zirconium oxide, nano-cerium oxide, etc. are used to absorb and reflect infrared rays to block the transfer of thermal radiation. Double thermal insulation , Sound insulation There are many bubble shells inside, and the sound conduction coefficient is low. It can not only use the air bubble shell to block sound transmission and reduce noise, but also use nano-alumina, nano-zirconium oxide, nano-cerium oxide, etc. to absorb sound waves to reduce noise and sound insulation. , Anti-corrosion Form a hard ceramic layer on the surface of the object to prevent the entry of air, corrosive gas, water, etc., and achieve a super anti-corrosion effect Features ensure the use of this coating It has a long service life, so the development and application of nano-transparent heat-insulating coatings on the surface of ordinary glass, organic glass and other transparent carriers is not only environmentally friendly and energy-saving, but also economical and practical. In today's society where the energy crisis and environmental protection pressure are increasing, thermal insulation coatings will have good application prospects. Due to high energy consumption, heavy pollution, poor safety and other reasons, it will gradually withdraw from the stage of history. With the establishment of a market economic system and the further improvement of people's living standards, as well as the adjustment of the energy structure, the Chinese market needs to update its backward traditional technologies and manufacturing processes in terms of environmental protection, energy conservation and emission reduction, and economic operation.
