Product Features: 1. smooth surface, the appearance of superior quality; 2. Easy installation, high efficiency, low compared to the cost of handmade; 3. The core material is a natural rock wool, iron blast furnace slag and other high temperature melting into wire, and then curing. Has better sound-absorbing, sound insulation and good fire resistance, the test proved that it has a fire resistance of 650 ℃, fire rating to A-level; 4. Interface tight conduction of heat is not easy; the furnace temperature 180 ℃, the outer plate a temperature below room temperature + 5 ℃. 5. poor load-bearing capacity. Rock wool sandwich fields of application] widely used in steel plants, simple activities room roof, wall, ceiling and cut off the air clean room main application metal Typical characteristics (color steel tile, aluminum, stainless steel, etc.), lighting tile, aluminum panels, sun panels, stone, concrete and other strong bond, especially sealing, high temperature resistance, fatigue resistance and good anti-follow performance good tensile strength and elongation, deformation and cracking of the interface adaptability UV protection, extend the useful life of the substrate aging resistance, weather resistance and corrosion resistance can be good with a strong acid-alkali resistance waterproof, fire and mildew , anti-bacterial, anti-algae and other elastic, wide area suitable for -50 ℃ ~ + 88 ℃ of use, excellent flexibility at low temperatures is still possible human stampede, stampede, except with the destruction of a variety of colors, well-matched metal board primary retention, low odor, on human health and the surrounding environment without harm, in line with environmental protection regulations VOC odor released, continuous construction solutions are: 1) to cover both sides of the roof reinforcement with rivets depending on the circumstances; 2 ), was cut 25 cm wide woven polyester fabric sewn, according to the actual cut into a shape corresponding to the ridge, then follow the same method as the above construction (five spread a cloth); 3) Gutter weld seam waterproofing treatment: 20 cm wide woven polyester fabric sewn by five spread a cloth waterproofing method recommended gutter seam welding, please reuse after handling the gutter protective coating as protective treatment gutter. 6, a single layer of metal roofing grassroots paint coating rate of 40 m / 20 liters, woven polyester fabric sewn utilization rate was 90%; the actual coating rate due to construction methods, different metal roofing situation is slightly different. 7, waterproof concrete parts as follows: 1) All nodes need to do waterproofing roof; 2) Water requirements: waterproof construction in strict accordance with the requirements of water treatment, in ten years the warranty period to ensure that no leakage occurred.
