Anchor nails are connected wall and Insulation board A kind of fastener between them is composed of galvanized screws, nylon expansion tubes and fixed discs. According to the different thickness of insulation layer, it can be divided into various specifications. It is widely used in building decoration. Main features: it has the characteristics of aging relief, temperature shock resistance, corrosion resistance, cold and heat resistance, high bearing capacity, high pressure bearing, and good tensile performance; It is not easy to deform, damp proof, slow vibration, absorb noise and have good insulation after loading. It is easy to install and can be hammered without special installation tools. cement The high-temperature and fire-resistant anchor nails used in the industry are made of chromium, nickel and titanium. External wall insulation The nails are mainly used to fix the insulation board in the external wall insulation system. The plastic expansion insulation nails are divided into various specifications, depending on the thickness of the insulation layer, and are widely used in building decoration. Thermal insulation nails are widely used in the thermal insulation layer of buildings. It can ease aging, resist sudden temperature change, prevent corrosion, cold and heat resistance; High bearing capacity, high bearing capacity and good tensile performance; It is not easy to deform, moisture-proof, vibration mitigation, noise absorption and good insulation after loading, so it is easy to install. The heat preservation nail is a special engineering plastic expansion nail used to fix the heat preservation board on the wall. The heat preservation nail is composed of three parts: one is the sleeve made of nylon; The second is the galvanized steel screw in the sleeve; The third is the nylon disc in front of the casing (used to cover the insulation board). Its length varies according to the thickness of the insulation board. It is widely used in anchoring of wall insulation houses. Galvanized screws solve the corrosion problem very well, with good durability, low heat transfer performance of nylon material, no cold bridge in winter, and energy saving.
