Common knowledge of coating: what characteristics should a good quality thermal reflective and thermal insulation coating have

Core tip: a good reflective thermal insulation coating for building should have the following characteristics (1) Solar thermal reflection coefficient and high hemispherical emissivity solar thermal reflection coefficient are called solar reflection ratio Their physical significance is: the ratio of the solar radiation flux reflected to the hemispherical space and the solar radiation flux incident on the surface of the object The physical meaning of hemispherical emissivity is the ratio of the emissivity of a thermal radiator in the hemispherical direction to that of a total radiator (blackbody) at the same temperature The higher the two values, the more significant the insulation effect Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: a good reflective thermal insulation coating for building should have the following characteristics (1) Solar thermal reflection coefficient and high hemispherical emissivity solar thermal reflection coefficient are called solar reflection ratio Their physical significance is: the ratio of the solar radiation flux reflected to the hemispherical space and the solar radiation flux incident on the surface of the object The physical meaning of hemispherical emissivity is the ratio of the emissivity of a thermal radiator in the hemispherical direction to that of a total radiator (blackbody) at the same temperature The higher the two values, the more significant the insulation effect 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,
