Product Description

Product Description:
Enhanced within reinforced type of polyvinyl chloride (PVC) waterproof membrane,  is a kind of thermoplastic PVC membrane, the membrane use polyester fabric or the glass fiber as reinforcement, through the special technology of extrusion coating method, make double PVC and polyester or in the middle of the glass fiber reinforced plastic layer combination become one formed by polymer membrane.
The formulated polyvinyl chloride (PVC) plastic layer combined with the reticulated polyester fabric provides excellent dimensional stability and low thermal expansion coefficient. The reinforcing bars and coils in glass fiber are fully kneaded so that interlaminar separation and water impregnation do not occur. Enhance the long-term performance of the directly exposed materials in the natural environment. At the same time, the unique coating on the surface of the materials makes the materials have self-cleaning function, preventing the dust and pollutants in the air from coloring on the materials
Used Areas:
All kinds of roof .eg steel structure roof, planted roof and so on.
Underground engineering, such as building basement, subways, tunnels, air Raid shelter, etc.
Other projects like artificial lake , dam, water reservoir,, grain storehouse, etc.
Reinforced quality features:
1)Polyester reinforced PVC waterproof membrane has excellent resistance to plant root.
2)Strong tensile strength, high elongation, good dimensional stability after heat treatment.
3)Excellent flexibility at low temperature, excellent resistance to the low and high temperature.
4)Excellent resistance to impact and perforation.
5)Fireproof : the membrane extinguish immediately after away from the fire source.
6)Easy and fast construction without pollution. 
PVC waterproof membrane is recyclable, environment-friendly and without heavy metal.
7)Excellent resistance to UV, chemical etching, long service life.
Service life: more than 20 years as roof waterproof material, more than 50years if used in underground waterproof . 
8)Repair project: Repair the damage place only and reduce the repair cost.
9)Various colors are available.

Packing:
packed with woven bags or black PE film for Reinforced/single ply PVC waterproof membrane.
Then with pallets.
Construction method:
1. Cold sticking method,
The construction method of pasting the pasting material on the base course by cold work is called cold adhesion method.
According to different waterproof design requirements, cold bonding can be divided into full bonding or local bonding.
(1) the method of full adhesion is the construction method of binding all PVC coils to the base.
1) during the construction, the first thing to do is to pre-lay the PVC coils on the surface of the base line of the line (no bonding first). It is required to be smooth, straight and not distorted.
2) the vertical lap width of the coil is 50mm, and appropriate cutting. It is transversely treated by butt joint, with no composite layer (class N) 200 ~ 250mm wide. PVC coiling lap welding.
3) fold half of the long edge of one or more sheets (about 10m), apply special adhesive to the base layer and the surface of the sheets respectively from the folding place. When the adhesive is dry to non-adhesive, close and paste the pre-laid sheet surface, and then use the pressure roller for compaction. Then fold the other unfolded part, continue from the fold as described above, and so on paste firm compaction. At last, the seam welding is carried out.
(2) partially paste the film. When the PVC coil material is laid, the coil material and the base material are pasted on the base by dot or strip sticking.
Spot sticking: the adhesive of the coil material to the base. Bond no less than 5 points per square meter with an area of 100mm x 100mm.
Strip adhesion: strip adhesion between the sheet and the base. Each sheet shall be no less than two binding surfaces and each sheet shall be no less than 150mm in width.
2. empty laying method
That is, when the PVC waterproof rolling material is laid, the rolling material and the base layer are only bonded within a certain width around the whole waterproof layer. Other parts of the non - bonding construction method. The construction process of the void shop method is as follows:
Basic leveling cleaning a spring line a rolling material pre-laid a rolling seam lap welding a special part processing a fixed, pressing a sealing material sealing side one acceptance.
First of all, the prelay of the coil refers to the full bonding method, and the width of the longitudinal lap is 50mm. Secondly, only the rolling material around the whole waterproof project is fully adhered and welded to the joint. The horizontal butt joint is adopted, and 200 ~ 250mm wide non-composite layer (class N)PVC coil is used to cover lap and weld.
3. Mechanical fixation
That is to say, the construction method of connecting the coil with base by mechanical fastening and fixing parts.
(1) during the construction, the pre-laying shall be carried out first, and the work can be referred to the full adhesion method. The longitudinal lap width is 100mm, of which 50mm is used as the fixing part. The fixing part shall be fixed on the structure layer through the insulation layer.
(2) according to the fixed spacing designed and calculated, drill holes with percussion drill first, and the aperture is slightly smaller than the external diameter of the fixed screw. After placing the fixator in place, reinforce and tighten it with an electric screwdriver. For each lap joint, the butt joint is applied horizontally, and the lap joint is covered by 200 ~ 2500mm wide (class N) reels.
The welding process of PVC membrane
The longitudinal lap width between PVC coils is 50mm and the transverse width is lOOmm. When the welding process is adopted, the welding nozzle is 45 to the welding direction. Angle, press roller and welding nozzle parallel and maintain about 5mm distance, rolling should not be too fast.
Use small welding nozzles with the width of 20mm welding nozzles, generally two, the welding temperature is controlled in level 6, and the effective width of each welding is 15mm ~ 20mm.
It is better to use a big welding nozzle with a width of 40mm, the welding temperature is controlled in the 7th gear, and the effective width of welding is 25mm.
Welding requirements: it should be pre-welding before welding, width should not be too wide, so that hot air will not overflow during welding and affect welding quality. The welding edge should overflow, but there should be no burning phenomenon.
