HDPE Geomembrane Welding Machine for Waterproof Projects

1.)Use with grounded 3-cord mains cable and 3-hole socket with a capacity not less than 10A (socket corresponds with welder plug, phase L connected to live wire, N to zero lines, phase to grounded protection liner), confirm that external lines have been well connected. Check that power is on-off state and regulate temperature control potentiometer and speed control potentiometer to 0 positions, press lever handle down to disengage pressure roller, then insert the plug.

2). Turn on the power and select a certain temperature and speed, take several narrow materials to try welding. Temperature selection may be different for the same material at different ambient temperatures and material thicknesses. To determine the best welding effect, adjust the speed to approximately 2m/min, and then fine increase it from low to high temperature -approximately 250℃-350.

3). Flatly and straightly trim the weld edges and frontage faced, with lower left and upper right overlapped. The overlap width is 100mm.

4). After temperature and speed have been determined, insert material to be welded between the two pressure rollers, make the machine body parallel with edges of base materials, and engage press lever handle for proper motion. Generally, only observation of deviation between welding mark and base materials is needed for the operator, and timely make the correction on a small degree.

5). When welding will be ended, timely press lever handle to disengage upper and lower pressure roller to prevent rubber wheel damage for long duration.

6). Excessive temperature high and low may occur because of thermal inertia. On this condition, temperature deviation may be compensated by speed regulation on a small degree.

Geomembrane Welding Machine is able to manufacture hot air or hot wedge welding systems designed for geomembrane liners, covers, geotextiles and more. We have the experience in the geomembrane industry to be able to help you reduce labor while increasing production.

Applications that use geomembrane welders include: Irrigation canals, ballpark covers, landfills, reservoirs and more.

Geomembrane Welding Machine

adopts advanced hot air heating system. With small, light and high speed, it perfects the welding quality even if corrosive materials and bad working environment. This machine is specially designed for tunnels, subway, water conservancy, aquaculture, biogas plants, landfills, chemical mining, sewage treatment, roof constructions and other waterproofing projects.

Application:

Welding of thermoplastic materials as well as single-ply flexible plastics and modified bitumen in the form of boards, tubes, profiles, lining membranes, coated materials, films, foams, tiles and sheets. The following procedures are possible: overlap welding, welding with rod, with tape, butt welding and melt welding.

For foaming, ending and sealing of the thermoplastic semi-finished materials and plastic granules.

Drying of water-damp surfaces.

Shrinking of heat-shrink sleeves, films, tapes, solder sleeves, preformed and mould part.

Soldering of copper pipes, solder joints and metal foils.

Defrosting of frozen water pipes.

Activating and dissolving of solvent free adhesive and fusion adhesives

Igniting of wood shavings, paper, coal or straw in furnaces
