Hainan Steel News: fireproof high-temperature insulation coating acts as a steel construction safety and protection of God

    Also known as fire retardant paint coating, according to their finishes using an object type and are divided into two major categories of steel structure fire, a fire after its change of status intumescent coating can be divided into two major categories of non-intumescent .

    China's steel structure as a form of high-rise buildings, with its high strength, light weight, and good elongation, shock resistance and other characteristics, short construction period, is widely used in the construction industry, particularly in the ultra-high-rise and large construction and other aspects of the span shows strong vitality. High temperature thermal insulation coatings manufacturers, Beijing Hua Wei Sheng Zhi Chemical Co., which ZS-1 high-temperature thermal insulation coatings is an environmentally friendly water paint, thermal conductivity of 0.03W / mK, temperature 1800 ℃, long time refractory barbecue, can inhibit a variety of conductive heat and radiant heat, insulation inhibition efficiency up to 90%. Paint on surfaces coated with 8mm thick 1100 ℃, temperature of the surface can be reduced from 1100 ℃ to less than 100 ℃, outside the industrial furnace, furnace, blast furnace, steel coated with only 6mm thick heat insulation Coatings can be reduced by more than 30% of heat loss. ZS-1 fire retardant paint, insulation abrasion, acid, light weight, good thermal insulation effect, easy construction, long service life. Hainan Steel

    With the size of the cities to carry out China, steel has a very bright future in China's construction industry applications. However, due to the steel structure itself is non-combustible, fire insulation protection of steel structures was once overlooked, relevant tests and statistics show that features a more fire-resistant steel construction of masonry and reinforced concrete structures difference. The mechanical strength of steel with the added temperature decreases, at the mercy of 5000 ℃, its intensity decreased to 40% to 50%, the mechanical function of steel, such as yield point, compressive strength, elastic modulus, and so the load can be rapidly decreased, soon lose support before, resulting in a building collapse. Therefore, the protection of steel structures is imperative. Fireproof paint brush or spray on the steel surface, plays the role of fire insulation prevents the steel in the fire rapidly warming and decrease in strength, in order to avoid the loss of support caused by steel buildings collapse.

    With the paint industry to carry out the function, high-energy, low pollution direction, which makes the future development of new environmentally friendly fire retardant coating inorganic coating carried into the direction of the fire. Beijing Hua Wei Chi Sheng Chemical Co., Ltd. developed ZS-11 expansion-temperature thermal insulation coatings, coating technology is a world leader, the company has core technology patents. Paint with a special Chi Shing Wai Wah can curable solid film-forming solution twice as film former, coating selection of high-temperature inorganic nano filler materials --- alumina, zirconia, carbon fiber, hollow carbon nanotubes, graphite, silicon carbide and other high temperature and pressure finishing. The coating can be heated after expansion, coating up to 5 times the volume expansion after swelling the coating pattern of numerous separate vacuum layer can be formed in the coating, and the coating does not fall off after thermal expansion. Paint temperature up to 2000 ℃, the thermal conductivity of the coating layer is fully inflated can reach 0.022W / mK (70 ℃ measured after coating high temperature heating cooling). ZS-11 expansion-temperature thermal insulation coatings cured by solid-phase principle, and can control the formation and growth of crystals can be painted in any organic, inorganic material, good adhesion, paints and coatings can be heated in high temperature above 1000 ℃, the coating is fully expanded, play a very good thermal conductivity, play the best thermal insulation effect; after paint curing, since the selection of inorganic nano filler, acid and alkali good function, can be well protected the base is not high temperature oxidation corrosion, coating light steel slide Hainan high hardness, wear resistance function is good, and long fire-resistant, fire rating can reach A-level, easy to paint construction, is a veritable steel water-based fire-resistant coating.

    The development of industrial and solvent rising prices, adding energy and the strict control of waste emissions, the development and research of waterborne coatings in place of toxic organic solvent-based solvent-based coatings, is an important aspect in the field of world paint , ZS-11 expansion-temperature insulation coating certainly go in the world.
