Common knowledge of coating: advantages and disadvantages of inorganic and organic thermal insulation materials

Core tips: inorganic thermal insulation materials are mainly concentrated in glass wool, rock wool, expanded perlite, micro nano thermal insulation board and other materials with certain thermal insulation effect, which can achieve class a fire protection The production of rock wool is harmful to human body, and workers will not want to construct it Moreover, the period of rock wool factory building is long It takes about two years from the factory building to the production At present, the supply of rock wool in the domestic market can not meet the requirements of use The weight of expanded perlite is large and its water absorption is high The heat preservation performance of micro nano heat insulation board is 3-5 times of that of traditional heat preservation materials It is often used in high temperature environment, but the price is more expensive Two 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: inorganic thermal insulation materials are mainly concentrated in glass wool, rock wool, expanded perlite, micro nano thermal insulation board and other materials with certain thermal insulation effect, which can achieve A-level fire protection The production of rock wool is harmful to human body, and workers will not want to construct it Moreover, the period of rock wool factory building is long It takes about two years from the factory building to the production At present, the supply of rock wool in the domestic market can not meet the requirements of use The weight of expanded perlite is large and its water absorption is high The heat preservation performance of micro nano heat insulation board is 3-5 times of that of traditional heat preservation materials It is often used in high temperature environment, but the price is more expensive In March 2011, the Ministry of public security stipulated the use of class a non combustible materials as thermal insulation system, and the future trend can be relaxed to Class B1 fire-resistant materials at most, and the development prospect of inorganic thermal insulation materials is still great Expanded perlite has a wide range of raw materials, simple production facilities, and is harmless to human body It is believed that it can be used as the main material in the future Organic thermal insulation materials, organic thermal insulation materials mainly include polyurethane foam, polystyrene board, phenolic foam and so on Organic thermal insulation materials have the advantages of light weight, good processability, high density and good thermal insulation effect, but the disadvantages are: aging resistance, large deformation coefficient, poor stability, poor safety, easy to burn, poor ecological environmental protection, difficult construction, high engineering cost, limited resources, and difficult to recycle Traditional polystyrene board and inorganic heat preservation board have excellent heat preservation effect, which are widely used in the current wall heat preservation material market in China, but they do not have safe fire-proof performance, especially the toxic gas generated during combustion In fact, the use of such materials has been limited in very small application fields in developed countries for a long time In recent years, the fire accidents caused by the use of polystyrene board thermal insulation materials in large areas of Chinese buildings are frequent, resulting in huge economic losses and casualties 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,
