Heat the filling glue in the heating chamber of the hot melt kettle, the sealant heated to melt until the required construction temperature of 193 ��. Note: In the process of heating the sealant, it is necessary to ensure that it is uniformly heated, it is recommended to use the heat transfer oil or hot air as the medium of the heating equipment, so as to avoid sealing charcoal phenomenon. Slot: According to the design of the slot size, adjust the width and depth of the slot machine and then slotting operations, the construction process according to the fission changes in time to adjust the slot size, and meet the minimum design requirements. Clear: clean the dust and debris in the tank and at least 5cm in both sides of the tank with compressed air guns or forest fire extinguishers. Preheat: pouring glue should be used when the road surface temperature exceeds 4 ��. The use of low temperature may reduce the viscosity, because the cracks at the water too much, if less than 4 ��, you can use the appropriate method of heating to ensure that the minimum requirements to achieve the limit. If it is required to seal below 4 �� C, it is necessary to ensure that the cracks are dry, anhydrous and debris. The sealant temperature should be maintained at a safe heating temperature, and the sealant should be inspected by a specialist to ensure stickiness. Filling: Under the condition of 193 �� C, the sealant is filled into the tank with a pressure nozzle with a scraper on the end of the irrigation joint. Maintenance: After filling with the irrigation glue, can not immediately open the traffic, the sealant must be fully cooled in the case of re-open traffic. The general cooling time of 15 minutes or so, the specific implementation, according to the temperature of the situation to master. single wheel pulley car damaged by pothole construction roller compactor sealcoating mix calculator
