Longyuan Sifang stones metal tile, metal tile vermiculite, villa tile, new roof tiles, gravel Hangzhou Longyuan Sifang gold tile is the first development of new products?, Titanium zinc alloy 铔 low surface ceramic particles attach to test Canada forever do not fade, titanium zinc metal Ya Unlike aluminum and zinc metal susceptible to air oxidation, while the intensity of the strongest adhesive is water-based acrylic adhesive glue is different from the poor weather, the Division I stones metal tile temperature of 70 degrees left and right hour surface without phenomenon, low temperature of minus 50 degrees surface delamination. Quickly became popular roofing products, it is the latest generation of materials currently roofing tiles. To wind earthquake, inexpensive, easy to install, but also insulation, roofing tiles Yatai chlorpyrifos-foreign cooperative research and development experts using adhesive, free to bend ensure afford particles of sand color with a special formula is by far not fade off, selling products at home and abroad, mainly in the face of high-end customers and building market. It is the latest generation of roofing series. Use waterproof material is waterproof design an important part of decisive significance. Now a wide variety of materials, different forms, different performance, the price level of disparity; each with different construction methods. Therefore, the material must be adapted to the requirements of the selected engineering requirements: engineering geology, hydrology, structure type, construction season, the local climate, architectural features and using special parts and other waterproof material has specific requirements. Use waterproof material is waterproof design an important part of decisive significance. Now a wide variety of materials, different forms, different performance, the price level of disparity; each with different construction methods. Therefore, the material must be adapted to the requirements of the selected engineering requirements: engineering geology, hydrology, structure type, construction season, the local climate, architectural features and using special parts and other waterproof material has specific requirements. 1, China has a vast disparity between north and south high and low temperatures, summer temperatures of the southern region for more than four degrees for several days, exposed roof waterproofing layer, prolonged exposure, prematurely pushing waterproof. Choice of material should be resistant to strong ultraviolet radiation, high softening point, such as APP modified bitumen membrane, EPDM rubber sheet, PVC sheet. ?? 2, South rainy, snowy northern, western drought. Annual rainfall of about 1000 mm over 15 provinces and autonomous regions, the rainy days of 200-day, the roof is always wet, poor drainage and stagnant water, quit for months, soaked with waterproof layer. Poor water resistance of the coating, and then emulsifying or prone to hydration reduction; intolerance blisters binder, seriously reduce the adhesive strength of the adhesive seam cracking polymer membranes, especially in the drainage gutter, I was soaked in water for a long time and leakage. Water should be used for this material, such as fiberglass tires, polyester tire of modified bitumen membranes or water-resistant adhesive bonding polymer membrane. ?? 3, the drought in the Northwest, evaporation is much greater than the rainfall, often missing roof rain water. Clearly the extent of water in these areas has decreased, as a secondary building fortification can meet the water requirements, if the make the protective layer, to achieve durable life. ?? 4, cold and snowy regions, cycling and some waterproof material not stand cold frost contraction, premature aging fracture. There are four or five months of the year is covered by white snow, snow lasting impregnated waterproof layer while melting snow and ice, frost resistance is not strong, water-resistant adhesive bad, will fail. These areas should use SBS modified bitumen membranes or welding seam of the polymer membrane, if the choice of low-temperature resistance of waterproof material, should be inverted roofing work. ?? 5, waterproof construction season can not be ignored. Also in North China Branch season cold, water-soluble paint can not be used when the adhesive at 5 ℃ reduces the adhesive properties that is at subzero temperatures but can not construction. Design is summer, when construction is thirty-nine, adhesives and congealing in case of concrete, the loss of adhesion. Web commissure not stick, causing construction failure, tarry duration, tuition materials. In summer, cold in the Northeast Construction of waterproof material, but in the cold winter, these waterproof layer completed, unable to withstand the ravages of frost shrink, waste premature failure. Learn to adapt the design should pay attention to the temperature of the selection of materials. ??
