Coating knowledge: coating is the first choice for building external facing materials

Core tip: external insulation can not only solve the problem of insulation, but also reduce the thickness of the wall which is too rich for the mechanical requirements, and reduce the cost of civil engineering External wall insulation is the most effective way to achieve building energy saving As the application of external facing materials, building insulation coating is still the first choice In China, the recommended external insulation systems are: polystyrene board thin plastering external insulation system, polystyrene particle thermal insulation slurry external insulation system, cast-in-place concrete composite non mesh polystyrene board external insulation system, cast-in-place concrete composite polystyrene board external insulation system, cast-in-place concrete composite polystyrene board external insulation system, mechanical fixed polystyrene board steel grid Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coating home news: external insulation can not only solve the problem of heat preservation, reduce the thickness of the wall too rich for mechanical requirements, but also reduce the cost of civil engineering External wall insulation is the most effective way to achieve building energy saving As the application of external facing materials, building insulation coating is still the first choice In China, the mature and recommended external insulation systems are: polystyrene board thin plastering external insulation system, polystyrene particle thermal insulation slurry external insulation system, cast-in-place concrete composite non mesh polystyrene board external insulation system, cast-in-place concrete composite polystyrene board external insulation system, cast-in-place concrete composite steel wire grid plate external insulation system, mechanical Fix the external insulation system of polystyrene board steel wire grid plate In addition, rock wool, polyurethane, extruded polystyrene board and other external insulation systems have also been developed and applied Building energy conservation in Western European and American countries At present, the widely used external wall external insulation system mainly adopts the thin plastering method of external insulation board There are two kinds of insulation materials: flame-retardant expanded polystyrene board and non combustible rock wool board, all of which take coating as the exterior decoration layer The application of external wall insulation system in Europe was initially to make up for wall cracks With low thermal conductivity, easy construction, oil resistance, acid resistance, alkali resistance and low pollution coefficient, the exterior wall thermal insulation coating is the most ideal thermal insulation material in the current exterior wall thermal insulation industry There are many kinds of exterior wall thermal insulation coating, including ceramic thermal insulation coating, hydrophobic silicic acid thermal insulation coating, rubber powder polystyrene particle exterior wall thermal insulation coating, etc Ceramic thermal insulation coating is a water-based liquid coating, which is made of ultra-fine hollow ceramic beads pretreated and high quality emulsion It has extremely high thermal reflectivity and emissivity, and can effectively reduce the energy consumption of building cooling in summer and heating in winter Hydrophobic silicic acid thermal insulation coating is composed of various high-quality thermal insulation materials such as high-quality sea foam velvet, aluminum silicate fiber, expanded perlite, organosilicon and high polymer It has excellent thermal insulation performance and is widely used in wall, tank, refrigerator, pipeline and other thermal insulation Polystyrene particles is a new type of thermal insulation material, which is composed of two main components: rubber powder and polystyrene particles At present, the relatively good exterior wall thermal insulation coating has good weatherability, low thermal conductivity, stable thermal insulation performance, high softening coefficient, freeze-thaw resistance and anti-aging It has strong adaptability to deformation at the base level, effectively prevents cracks on the wall surface, and the system has no cavity and strong anti negative wind pressure capability, and is suitable for multi-storey and high-rise buildings With good air permeability and strong respiratory function, it has not only good waterproof function, but also can drain the moisture of insulation layer; the construction is convenient and fast, and can be constructed in multiple points and layers; the fire resistance rating can reach B1 and above and many other comprehensive advantages Home of coatings is
