Good products, good quality tunnel fire retardant paint, Hebei, Yunnan region Beaulieu factory outlets

1, tunnel fire paint coating does not contain asbestos and hazardous materials, production, use and construction after no irritating odor. When the fire does not release toxic gases, smoke toxicity achieve AQ-1 level in line with environmental requirements. 2, good preparation by the factory, component packaging, construction site, construction mixture was stirred, easy to operate. 3, direct spray and trowel application, drying fast curing. 4, light coating, bonding firm, high strength, aging resistance and superior water resistance. Performance indicators 1, according to HC-curve detector (GA98-2005) container status: white granules, powder mixture; Drying time: dry ≤24h; dry density (kg / m): ≤650; bond strength (Mpa) : ≥0.2; compressive strength (Mpa): ≥0.5; Water resistance: 720h After the test, the coating does not crack, layer, fall off, allowing a slight swell and change color; Alkaline: After 360h test the coating no cracking, layer, shedding, allowing a slight swell and change color; Acid resistance: after 360h test, the coating does not crack, from the floor, shedding, allowing a slight swell and change color; freeze-thaw cycle test: by 15 runs After coating does not crack, layer, loss, color; fire resistance: coating thickness up to 18mm ± 2mm, refractory time is 2 hours. 2. Description of different fire resistance fire resistance of / h 1.5 2.0 2.5 3.0 3.5 coating thickness / mm 10 18 23 27 30 Construction Construction of Tunnel fire coating layered construction technology commonly used intermittently, sub base layer (fireproof layer) and the surface (color layer) construction. 24h during construction and after construction, ambient temperature not lower than 4 ℃, in order to protect against frost damage. In the extremely dry and hot conditions, it should create the necessary conditions for the conservation, prevent excessive water loss coating. 1, the construction machinery: mortar mixer, special spraying equipment (squeeze mortar pump, air compressor), smear mortar special iron, cleaning utensils, transport and so on. 2, the construction preparation: (1) the cleaning tunnel concrete surface dust, oil and other clean, and the water spray wetting; (2) repair the uneven place, to ensure smooth concrete surface tunnel; simultaneously particularly smooth surface of the concrete place, requirements for mortar surface; (3) the leak must trap seal. 3, Base Construction: (1) water and paint with (0.70 to 0.75): 1 ratio, with mixer mixing 20min (make sure the mixing time, with the mix with paint to use), into a thick syrup; (2) with a small amount of paste to make lateral distance of strip thickness 2.5m mark, as the spray of reference; and (3) with a sprayer for spraying from the waist to the top of the tunnel (from the bottom), each coating thickness 3 ~ 8 mm; (4) After the first spraying basic dry, continue spraying the second, and so on, until the painting to design thickness; (5) due to spraying the surface is not smooth enough, so after the last spraying, immediately padding with slurry for manual leveling, trimming, coating smooth surface, and ensure that the coating thickness to meet the design; (6) after the completion of the grassroots, requires coating the surface, smooth and clean. 4, surface construction: basic dry grass after molding (about 3d), surface construction can be carried out (for demanding projects, such as municipal engineering, construction best before scraping the surface layer of putty in the grass surface) . Surface can be used gun, wool brush, roller and other equipment for the construction, stencilled requires uniform, smooth, no color. The dividing line between the requirements of different colors straight and clear. Conservation of conventional natural conservation 28d, the same curing conditions and ordinary concrete, coating if damaged, should be repaired. Construction Notes (1) while stirring the slurry is too dry, it may be appropriate to increase the water-cement ratio, subject to appropriate construction; (2) mixing, spraying, painting process, scattered, rebound slurry may recover in time use; polluted and more than 2h of unusable; (3) coating the bag should be used immediately once opened, moisture caking coating shall not be used; (4) the construction process can be designed according to the coating thickness and application conditions, appropriate adjustments . Packaging and Storage 1, the product is lined with plastic woven bag, 40kg. 2, this product should be in a cool, dry warehouse storage, the storage period of six months. 3, the product is non-flammable, non-explosive, non-toxic, non-corrosive of security products. Storage and transportation, attention sealed to prevent moisture and rain ingress, damp material that is invalid
