Supply Guozhen series two-component polyurethane spray gun. Two-component polyurethane waterproof coating spray gun hot melt method. Use flame spray gun or blowtorch to aim at the bottom surface and base layer of the coil to heat evenly. When the asphalt on the surface begins to melt and becomes black and bright, bake it while baking. Spread the roll material and compact it with a pressure roller. At the same time, attention should be paid to adjusting the flame size and speed to keep the asphalt temperature between. After the construction is completed, the overlapping edges should be sealed with cold adhesive.
In the cold bonding method, use a rubber scraper to evenly apply polymer modified asphalt adhesive or cold mastic and other cold adhesives on the surface of the base layer, and control the thickness to be uniform. Use a rubber stick to push the roll while laying it out. Remove the air until compacted. When the ambient temperature is lower than ℃, the hot melt method should be used to treat the overlapping parts and coil closing parts.
A two-component polyurethane spray gun includes a gun body, a trigger, a feed pipe, a discharge pipe, a valve and a gun barrel. There are two feed pipes and two discharge pipes, which are arranged side by side in the gun body. The valve There are two, and the characteristic is that a stirring device is provided in the gun barrel, the valve includes a stuffy cover, and the stuffy cover is arranged on the inlet of the discharge pipe. The advantage of this utility model is that after the two-component liquid material A and B enters the barrel, it flows forward under the action of pressure, thereby pushing the spiral mixer to rotate, so that the two-component material is fully stirred, more uniform, and sprayed out After solidification, the strength is higher. At the same time, the valve's cover structure makes the cover tightly pressed on the discharge pipe under the action of pressure when the utility model is not in use. The greater the pressure, the tighter the pressure. This ensures that there is no leakage at all. This makes the operation cleaner and more environmentally friendly, saving production materials and reducing production costs.
