The welding machine for a geomembrane

The welding machine with a hot wedge is used:

for welding of a film in the form of a tunnel, for sealing in the sphere of hydraulic engineering, for a waterproofing in the construction sphere, for isolation of razlchny waste (garbage). The welding machine with a hot wedge of LST 900 carries out heating through a metal heating element, satisfies to various qualitative characteristics of materials and various standards of thickness of a construction film, we will apply to all types of a film – RE (polyethylene), PVC (PVC), EVA, HDPE (PND), RR (polypropylene) and other materials which are subject to a termosplavka.

The system of automatic maintenance of constant temperature used in a temperature regulator of the welding machine provides high precision, reduces the level of temperature fluctuations; the speed regulator automatically regulates speed and stabilizes tension in an electric chain. The established level of speed remains in case of loadings [when welding a seam] on an inclined plane, and also on the perpendicular plane (covering). Welding is carried out by compression of heated surfaces. Pressure upon a polyethylene film is transmitted with use of the cranked lever through the leading clamping rollers. The double welding seam with so-called "test air" the channel is formed. Durability of a welding seam – 85% of the main metal. Functions of the operator when carrying out welding by these devices for welding of polymers are reduced only to selection of the mode of welding parameters (speed of welding and temperature of a hot wedge) and correction of a trajectory of the device at the movement along an overlap. Performance data of the welding machine with a hot wedge allow to make work more convenient and stable, to increase efficiency of welding. The device finds broad application in the sphere of a construction of high-speed highways, the subway, tunnels, reservoirs, channels, musorokhranilishch, in the construction sphere for a waterproofing.
