The waterstop hot melt welding machine is composed of two parts: a mold and a control box. The mold is equipped with an electric heating element connected to the control box. The interface shape of the mold is adapted to the heated element. There is a temperature measurement facility in the middle of the mold to mix the film. Similar to the vulcanized rubber material at the joint of the waterstop, the vulcanizing agent in the large mixed rubber sheet diffuses to the joint interface and cross-links with the remaining double bonds of the vulcanized rubber to form a co-vulcanized system, making the joints integrated and pressurized. The vulcanization temperature and vulcanization time need to be strictly controlled during the process. Characteristics of the hot melt welding process for waterstops
The hot melt welding machine for waterstops is easy to operate, has automatic temperature control, and the welded joints are smooth, firm, and have good waterproof performance.
The waterstop straightening fixture has the characteristics of simple processing and convenient operation. The waterstop is light in weight, easy to install and has good straightening effect.

Operation points
Waterstop connection Waterstop installers must check the length of the waterstop before invert concrete construction examine. The length of the waterstop must be greater than the invert of the section. If the length is insufficient, extend the waterstop to facilitate connection for the next waterstop installation.
How to use the hot melt welding machine
Cut and align the two waterstop joints.
b. Fill the reserved seams with the hot-mixed rubber sheet.
Wrap the waterstop seam with wide, long and thick raw tape for a week and press it tightly with your hands.
d Place the connection joint position on the hot melt welding host.
Adjust the temperature ℃ that needs to be heated on the temperature controller.
During the heating process, constantly adjust the jack until the gap between the two molds just reaches the thickness of the waterstop.
Heating time. Leave to cool to room temperature.
Inspection of the integrity of the waterstop. Before installing the waterstop, the integrity of the waterstop must be inspected to check whether the waterstop has defects such as breakage, damage, and perforations. If there are defects, the defective parts should be repaired immediately. Hot melt vulcanized rubber is used for repair.
Waterstop straightening: Use a special straightening fixture to straighten the waterstop within the length of this construction. The special straightening fixture is composed of two pieces of angle steel and a type clamp.
When setting out the waterstop position, the construction surveyor used red paint to draw the ⊙ symbol as a mark on the side wall at the end of the invert. And inform the waterstop installer in writing the positional relationship between the waterstop and ⊙.
Installation and positioning of the waterstop: When the invert concrete is poured close to the bottom of the waterstop, fix the waterstop and straightening clamps on the invert steel bars and formwork. The fixing method uses iron wire to tighten the clamps on the aluminum alloy fixture, the invert steel bars and the formwork so that the waterstop does not shift during the concrete pouring process.
Concrete within the buried height range of the waterstop for concrete pouring should be poured symmetrically on both sides of the waterstop. Only in this way will the waterstop not be offset. When tamping concrete, tamping should be done symmetrically on both sides of the waterstop and gradually move forward. It is prohibited to tamp one side first and then the other side.
Removal of the straightening clamp The waterstop straightening clamp can be removed only one hour after the concrete pouring is completed. When dismantling the straightening clamp, first cut the wire, then loosen the bolt of the clamp, and finally take out the angle steel.
