Gypsum-based fireproof coating takes gypsum as the main substrate and adopts inorganic lightweight thermal insulation and fiber materials consisting of powder. Compared with cement-based fireproofing coatings, gypsum-based coatings are green and environmentally friendly, the raw materials are low-carbon and energy-saving, and the materials are light and of low density. At the same time, it has strong adhesive force, good deformation ability, excellent fire resistance, and can provide up to 4 hours of fire protection against fiber and hydrocarbon fires. The finished product is not easy to crack and fall off, breaking through the bottleneck of cement-based layered and channelized construction, and the product can be realized in one spraying construction molding. It is suitable for indoor and outdoor steel components, pressed steel plates and prefabricated concrete components. At present, the thick fireproof coating is mainly divided into three types according to the base material: cement-based, gypsum-based and cement-gypsum composite-based.
Advantages:
1、Structural load lightness
2、Construction convenience and rapidity: 15-minute curing technology, construction speed, saving labor.
3, low cost: spraying process construction, one-time molding
4、Construction quality: gypsum-based flexibility, strong resistance to deformation, will not crack, hollow drum, falling and falling off.
5, green zero pollution: inorganic materials do not contain asbestos, benzene and fiberglass substances, VOC content (organic volatile organic compounds) is zero, the heavy metal content is zero.
6. Long-lasting fire-resistant performance: Neutral material, does not promote steel corrosion; stable fire-resistant performance.
7, sound insulation effect is better: has a certain sound insulation effect.
8, a variety of decorative: can be directly batch putty, brush all kinds of paint.
9, anticorrosion protection and long-lasting: gypsum-based fireproofing coating can play a protective effect of anticorrosive coating on steel structure, which can help anticorrosive paint to enhance the anticorrosive life to more than 20 years.
