Long gap between the three wood approach: taking into account drainage, cleaning and minor thermal expansion, contraction and other reasons, wins dimensional profile installation, edge to edge, you must leave appropriate gap between the head to head. Edge to Edge: wins Dimensional Cutting edge to edge between the requirements of ≥4 mm: When installed in a cold climate, ≥4 mm clearance requirements. Head to head: the gap between wins dimensional profile head to head size depends on the length of the sections, the temperature during installation, the thermal expansion coefficient profiles (ζ≈0.9 × 10-4), as well as local highest possible temperature. Head to head clearance calculation: For a L meter long profile WPC okay, local highest possible temperature within one year Tmax, when the temperature is T installed wood flooring brand, then this root profiles installed head gap should be reserved Δ L = ζ × (Tmax? -T) × L. For example: a 2 m long profile, installation day temperature is 10 ℃, the hottest day of the year at 40 ℃ wood flooring manufacturers, then install the root profile of head should be kept gap: Δ L = ζ × (Tmax-? T) × L = 2000 × (40-10) × 0.9 × 10-4 = 5.4mm What is ecological wood? It is extruded with a wood fiber and resin, and a small amount of polymer material, having waterproof, decay, corrosion, thermal insulation, anti-aging and anti-ultraviolet, and other characteristics, can be long-term use in complex environments. As a result of the extrusion process, ecological wood products can be color, size, shape, according to the need to control, truly on-demand WPC, minimize costs and protect the forest resources. And ecological wood almost free of harmful volatile substances and gases detected by the authorities, the release of formaldehyde is only 0.1 mg / l, well below the 1.5 mg / liter of national standards, its fire index for the B1 level, only inferior aluminum buckle, green low-carbon green material a real sense, but also recycling. WPC quotes, Xinjiang wood floor, a long three-building materials provided by the Chongqing Municipal Building Materials Co. three years. Chongqing City for three Building Materials Co. (www.cqjsmsjc.com/) strong, credible, Chongqing Liangping materials processing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead three building materials and you work long into the brilliant, for a better future!
