Resin tiles, a new breakthrough in the roofing building materials industry, uses advanced three-layer co-extruded technology, ultra-high weather resistance, and a high quality, durable and durable roofing material.ASA engineering resin, extruded, lightweight and weight resistance, waterproof and heat insulation, thermal insulation, shock resistance, corrosion resistance, self-cleaning ability are very strong, but when it comes to his high-temperature resistance, I would like to introduce you to how to measure the high-temperature resistance of resin tile.
In terms of mechanical properties: the coefficient of expansion of synthetic resin tiles is4.9*10mm/mm/°C, the shape of the dig has two-way tensile properties, dozens of temperature changes are large, the dig's expansion and contraction properties can also be digested by itself, which can ensure that the resin tile a few and dimensional stability.
In toxicity: in the smoke generation at the same time, the material combustion or pyrolysis also produces toxic gas, resulting in building fires in the death of people for the number of people who died of smoke poisoning, so the potential toxicity of the material must be emphasized. Resin tile to reach the combustion point of combustion will form a smoke exhaust band, and combustion does not produce melt droplets.
In the combustion performance: synthetic resin tile tree flame retardant products, his oxygen index is less than20, its raw materials are acrylonitrile, styrene and acrylic rubber composed of ternary polymers, that is, a class of synthetic polymers, resin tiles as a new generation of environmentally friendly chemical building materials, the process of renewable production, the amount of flame retardant, so that the resin tiles are not easy to combust, according to the internal design of the building fire code, the resin tiles are judged to be flame-retardant B1 level, fire rating B1 level.In the fire, it is extinguished when it leaves the fire, does not produce dripping and melting in the fire, does not play the role of combustion, does not aggravate and accelerate the combustion of other materials, and in the fire, it will form its own smoke evacuation belt, thus effectively reducing the phenomenon of poisoning of the people in the disaster.
In terms of thermal insulation performance: in terms of high heat insulation from fire, his thermal conductivity and heat capacity are two very important influencing factors, expansion, contraction, deformation melting, pulverization have a great impact on the performance of thermal insulation, construction methods and thermal insulation is directly related to the coefficient of thermal conductivity of synthetic resin tiles for the0.325w/m.k, about 1/310 of clay tiles, 1/5 of cement tiles, and 1/200 of 0.5mm thick color steel tiles. by comparison, it can be seen that the thermal conductivity of synthetic resin tiles does not lose to ordinary roof tiles.
