How to make joints with rubber waterstop hot-melt welding machine? Rubber waterstop uses adhesive for cold joints and hot vulcanization molds for hot joints. Then, how to use rubber waterstop hot-melt welding machine for joints?
Prepare the rubber waterstop hot-melt welding machine required for the rubber waterstop joint, turn on the power 30 minutes in advance to preheat the hot-melt welding machine, and the preheating temperature should reach 130-150℃.
Cut the rubber waterstop joints neatly, use a grinder to polish the end, the width is not less than 5cm. Cut a 10cm wide raw rubber connecting strip and a 1cm wide raw rubber connecting strip respectively. Unplug the power, close the rubber waterstop hot-melt welding machine, and lay the waterstop joint on the bottom plate of the welding machine. Place the 1cm wide raw rubber connecting strip into the center of the seam. Then spread the 10cm-wide raw rubber helper strip on the polished surface of the waterstop to ensure that the width of the seam is equal on both sides.
Close the rubber waterstop hot-melt welding machine and tighten the bolts. After connecting the power supply for 5 minutes, tighten the bolts again and continue to heat for 5 minutes. The power supply is closed and the welding is completed. After the rubber waterstop hot-melt welding machine cools down for 20 minutes, take out the rubber waterstop, check the appearance of the welding, and then install it after passing the test.
