HDPE is mainly used in waterproofing projects such as landfills and wastewater treatment plants. LDPE is mainly used for tunnel composite lining and is not suitable for exposed roofs. EVA is mainly used in subway projects, tunnels, air-raid shelters, dams, artificial lakes, industrial waterproofing and other projects. ECB is mainly used for waterproofing of subways, roads, dams, tunnels, civi
Advantages and disadvantages of PE self-adhesive waterproofing membrane Polyethylene polypropylene composite waterproofing membrane uses polyethylene resin as the main waterproof layer, double-surface composite polypropylene filament non-woven fabric as a reinforcement layer, and a hot melt direct pressure process for one-time composite molding (low grade) The product uses a secondary compound mol
Is the side of the composite PE film The correct representation method of SBS waterproof membrane: SBS Ⅰ PY PE PE 4 10 GB18242-2008; when simplified, it is written as: SBS Ⅰ PY PE PE 4. The meaning of the expression (SBS waterproof membrane) (type I) (polyester felt carcass) (the upper surface is PE polyethylene film surface)) (the lower surface is PE polyethylene film surface) (thickness is 4mm)
Introduction of PE membrane waterproof membrane PE membrane waterproof membrane, also known as polyethylene membrane waterproof membrane, has the characteristics of high mechanical strength, aging resistance, strong puncture resistance, large friction coefficient, flexibility and corrosion resistance. Chinese name polyethylene film waterproof membrane foreign name PE alias polyethylene geomemb
Waterproof membrane introduction Waterproof coiled material is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater leakage. It is a flexible building material product that can be rolled into a roll shape as the engineering foundation There is no leakage connection with the building, which is the first waterproof barrier for the wh
Precautions for first-class polyurethane foam board Thermal insulation materials, as the name suggests, can be used for thermal insulation. Thermal insulation can collect excess heat. In buildings, thermal insulation materials can be used to isolate the outflow of heat in the room, thereby playing the role of thermal insulation. This function of thermal insulation material makes it extremely popu
1. XPS extruded board must ensure that the aging meets the 42-day requirement under natural environmental conditions. If the construction period is tight, backup measures should be taken for 5 days under 60-degree steam curing conditions. In order to avoid the insufficient aging period of the XPS board, it will continue to shrink after being placed on the wall, causing cracking, warping and deform
Brief introduction of XPS extruded board The main raw material of XPS extruded board is polystyrene resin, with an average molecular weight ranging from 170,000 to 500,000, Mw/Mn ≥ 2.6, and auxiliary materials including additives and foaming agents. Most of the blowing agents used by foreign companies do not contain halogenated carbon, but use hydrocarbon blowing agents with a faster replacement
