Expanded polystyrene board expanded polystyrene board (eps board) the full name of polystyrene foam board, the material is made from polystyrene beads containing a volatile liquid blowing agent, after pre-heating in the mold and heated hair white solid having a fine closed cell structure. Benzene board is flammable insulation effect, but easy to absorb water, and cause weight gain distortion, waterproof measures must be done in place, otherwise it will directly affect the life of the fire performance coupled with low one thin stone slab, construction complex process, require additional mesh, so the state is generally not prescribed wall insulation polystyrene board. Extruded sheet extruded polystyrene board (xps board) the full name of extruded polystyrene foam board, the material is polystyrene resin supplemented by heating a mixture of polymer, while injecting a catalyst, and then the continuity of closed-cell extruded extrusion rigid foam insulation board phenolic foam board Phenolic insulation board phenolic foam, phenolic foam is a new type of non-flammable, low smoke and fire insulation material, which is joined by a phenolic resin foaming agents, curing agents and other additives made of closed-cell rigid foam. 5, chemical anchor quality varies greatly. Currently one of the thin stone plate contact, after the curtain wall industry plus the anchor is the most widely used chemical anchor. But more miscellaneous chemical anchor brand, fish, quality varies. Chemical anchor anchorage glue acts as bonding concrete substrates and Anchorage. Currently, a variety of chemical constituents appearing on the market of chemical binders, more common is a modified epoxy resin, ethylene acrylic resins and unsaturated resin categories. Anchorage glue directly affect the physical and chemical properties of the anchoring effect, in addition to several imported brands promotional materials marked with durable plastic anchor, temperature, freezing and other test indicators, most of the manufacturers of products introduced only "anti-acid, anti-aging, heat fire, low temperature sensitivity, "the vague declaration. Despite the large pullout test site can meet the design requirements, but because of the durability of the plastic anchor currently only predicted by laboratory tests, and how the influence of high temperature welding plastic anchor, no say where, so the chemical anchor choose the one not freeloaders thin stone slab quality, we must use all the performance indicators are in line with the design and specification requirements, while the market reputable products. In summary, the hanging stone walls in order to ensure safety, we must start from the basic material selection should not only consider the immediate, while the use of low cost materials wholesale thin stone one board to seat belts to risks. At the same time to strengthen the management of the construction process, do tests, installation and training of workers, and enhance their quality of security awareness, avoid operating or non-standard workers' quality and safety awareness is not strong security risk to the stone walls. In short, we make stone walls become a beautiful landscape of urban road construction, rather than a gold time bomb. One thin stone plate, take off decorative (certified), thin stone slab from one takeoff Decoration Engineering Co., Ltd., Shandong offer. Shandong takeoff Decoration Engineering Co., Ltd.
