ZS-221 Type A sunscreen Thermal insulation coating It integrates reflection, radiation, infrared shielding and nanometer A new type of sunscreen, heat insulation and cooling integrated hollow microspheres coating The coating can reflect the solar infrared, visible light and ultraviolet light in the wave band range of 200nm -- 2500nm, with a thermal reflectance of more than 90%, so that the heat from the sun does not accumulate after the object surface is irradiated. The coating can also automatically radiate heat to radiate the residual solar heat on the object surface into space, The residual accumulated temperature of the object is reduced. Even in cloudy days and nights, the coating can radiate heat to reduce the temperature. At the same time, nano hollow beads with low thermal conductivity are placed in the coating to isolate the heat transfer. Even when the atmospheric temperature is very high, the coating can also isolate the external heat and conduct it to the interior of the object.
In 2011, the sunscreen and heat insulation coating improved by the company as a whole added new inorganic materials such as carbon nanotubes, carbides and nitrides. New materials such as carbon nanotubes, carbides and nitrides have strong electromagnetic shielding and aging resistance. The heat insulation coating can form a strong infrared shielding stack after adding these materials, The high electromagnetic wave emitted by these materials forms a superimposed infrared shielding layer on the surface of the coating. When the infrared ray of the sun does not reach the thermal insulation coating, and the light from the sun is still a certain distance away from the coating, the superimposed infrared shielding layer will emit electromagnetic shielding layer, which can effectively shield a large amount of reverse solar light in infrared ray, Reduce the exposure of sunlight and infrared rays to sunscreen and heat insulation coating. The four major functions ensure the cooling of objects coated with heat insulation coating, ensure that the internal space of objects can be kept at a constant temperature, and create a cool and cool space environment.
In the summer when the sun is strong and direct, ZS-221 Type B sunscreen and heat insulation coating The surface temperature of the object can be lowered by more than 25 ℃, and the temperature can be lowered by more than 5 ℃ or the same as the atmospheric temperature in cloudy days and nights. ZS-221 Type B sunscreen and heat insulation coating It has good mendability for objects with small cracks, and plays a good role in waterproofing and leakage prevention. ZS-221 Type B sunscreen and heat insulation coating There are a variety of colors to choose from, and different colors of sunscreen and heat insulation coatings can be applied according to different color requirements. In addition, the coating is smooth and smooth, with good hydrophobic and self-cleaning properties, so ZS-221 Type B sunscreen and heat insulation coating It is a new sunscreen, heat insulation, energy-saving and long-life coating integrating heat insulation and cooling, thin layer decoration, self-cleaning and waterproof, moisture and ultraviolet aging resistance, acid and alkali resistance, and anti-corrosion, with a service life of 25 years.
ZS-221 Type B sunscreen and heat insulation coating It can be widely used in construction, chemical industry, petroleum, electricity, metallurgy, shipbuilding, textile, storage, transportation, aerospace and other industries to cool down, save energy, and create a comfortable and cool human living and working environment.
