Heat welded roofing membrane Polyvinyl chloride PVC waterproof membrane
is a kind of polymer waterproof sheet with excellent performance. It uses PVC resin as the main raw material to add plasticizers, anti-ultraviolet agents, anti-aging agents, stabilizers and other processing aids, and is produced by extrusion Molded polymer waterproof sheet.
This product adopts a unique product formula, the product life is far beyond the general waterproof material, the entire waterproof system has a long life, the roof is more than 20 years, and the underground is more than 50 years.
Reinforced white epdm membrane for roof waterproofing of industrial and civil buildings, including planted roofs, sloped roofs, and flat roofs; underground waterproofing of buildings; waterproofing of reservoirs, pools, canals and basements; tunnels, grain depots, civil air defense projects, landfills, and artificial Lake and other waterproofing.

How to install pvc membrane roll:
A. Empty shop
That is, when paving the PVC waterproof coiled material, the coiled material and the base layer are only bonded within a certain width of the entire circumference of the waterproof layer; the rest of the construction method is not bonded. The construction process of the empty paving method is as follows:
Grassroots leveling, cleaning, elastic line, roll material pre-laying-roll material seam lap welding-special part treatment-fixing, edge holding-sealing material edge sealing-acceptance.
First, the coil pre-laying refers to the full bonding method, and the longitudinal overlap width is 50mm. Secondly, only fully glue the coils around the entire waterproof project and weld the lap joints. Horizontal butt joint treatment is adopted, and 200-250mm wide non-composite layer (N type) PVC coil material is used to cover the overlap and welding.
B. Mechanical fixation
That is, the construction method in which the coiled material is connected with the base layer by mechanical fastening and fixing parts.
(1) During construction, pre-laying should be carried out first, and the full adhesion method can be referred to. The longitudinal lap width is 100mm, of which 50mm is used as a fixing part, and the fixing part needs to pass through the thermal insulation layer and be fixed and covered on the structural layer.
(2) According to the designed and calculated fixed spacing, first punch holes with a percussion drill, and the hole diameter is slightly smaller than the outer diameter of the fixing screw. After placing the fixing parts in place, use an electric screwdriver to reinforce and tighten them, and then cycle operations in turn. Weld each lap joint, adopt butt joint treatment in the transverse direction, and cover the lap joint welding with 200-2500mm wide non-composite layer (N type) coil material.
C. PVC waterproof coiled material welding technology
The longitudinal overlap width between PVC waterproof membranes is 50mm, and the horizontal width is 100mm. When the welding process is adopted, the welding nozzle forms a 45° angle with the welding direction, and the pressure roller
Parallel to the welding tip and keep a distance of about 5mm, the rolling should not be too fast.
Use a small welding nozzle with a welding nozzle width of 20mm for welding, generally two passes, the welding temperature is controlled at the 6th gear, and the effective width of each pass is 15mm-20mm.
Use a large welding nozzle with a welding nozzle width of 40mm should be one welding, the welding temperature is controlled at the 7th gear, and the effective welding width is 25mm.
