Insulation nails, the choose and buy of exterior wall thermal insulation nails, bolts
on the market sell insulation nails, expands external insulation nails, nail, swell tubes are diverse, although perhaps color appearance is not the same, but in general use are the same. First of exterior wall thermal insulation system used in the insulation board insulation nails fixed, anti-aging, temperature resistant mutation, anti-corrosion, cold heat; High bearing capacity, high pressure, good tensile performance; After loading is not easy to deformation, moisture, low vibration, noise absorption and excellent insulation characteristics, such as device is simple. Heat preservation exterior wall thermal insulation nails, nail and the anchor nails, plastic wall thermal insulation nails, nail wall insulation nails, swell insulation, heat preservation nail swell bolt, etc. Insulation nails, nail swell insulation quality, directly affects the quality of the thermal insulation engineering construction, good thermal insulation nails, plastic insulation nails, swell heat preservation nail can be used for 50 years to 70, to become old, yea, with construction of exterior wall thermal insulation nails, poor quality of thermal insulation nails, swell heat preservation nail can be used only more than 10 years to 20 years, due to poor insulation nails, exterior wall thermal insulation nails used substandard stature is short, the wall of the external wall thermal insulation layer break, fixed a new make of exterior wall thermal insulation engineering than a heat preservation engineering cost many times higher, caused the serious wasteful of time, money and resources. So, choose a good heat preservation nail expands, exterior wall thermal insulation nails, nail, plastic insulation insulation nails, nail swell bolt is particularly important.
heat preservation nail specification has two, one is JG149 - 2003 < Swelling polystyrene board thin plastering exterior insulation system specification: single bearing capacity of heat preservation nail acuity 0. 3 kn, 0 or higher thermal conductivity. 004. The other is a new specification JG158 - 2004 'powder polystyrene particles exterior insulation system specification: single bearing capacity of heat preservation nail acuity 0. 8 kn, 0 or higher thermal conductivity. 004, heat preservation nail outside dish 56 mm or higher. Insulation nails according to the raw material is divided into plastic swell insulation heat preservation nail nails and nylon is puffy, according to the layout is divided into separate insulation heat preservation nail and one-piece nail. On the basis of thermal insulation layer of its thickness is not the same, can choose the different heat preservation nail standard. Heat preservation nail composed of three some: it is made of nylon or plastic casing; Second, the casing of galvanized steel screws may stainless steel screw; 3 it is nylon or plastic disc before the casing.
