　　crack sealantmanufacturer Share the operation process of sealant filling.

　　Cleaning seams:

　　Use compressed air or forest fire extinguishers to clean and dry the dust and debris within a range of at least 5cm on both sides of the tank.

　　preheat:

　　The sealant should be used when the road surface temperature exceeds 4 ℃. Using at low temperatures may reduce viscosity, and there is too much water vapor in the cracks of squid. If the temperature is below 4 ℃, appropriate heating methods can be used to ensure that the minimum requirements are met. If sealing is required below 4 ℃, ensure that the cracks are dry, free of water and debris. The temperature of the sealant should be maintained at the heating temperature, and the sealant should be inspected by personnel to ensure adhesion.

　　Grouting:

　　Under the condition that the sealant reaches 193 ℃, use a pressure nozzle with a scraper on the sealing terminal to evenly pour the sealant into the groove.

　　Maintenance:

　　After sealing the seam with sealant, traffic should not be immediately opened until the sealant has cooled sufficiently. The general cooling time is about 15 minutes, and the specific implementation can be flexibly controlled according to the temperature situation.

　　Key points to note:

　　(1) The temperature of the sealant during construction should reach 193 ℃, but not exceed 204 ℃.

　　(2) The slot size should meet the low design requirements, that is, the width should be ≥ 1cm and the depth should be ≥ 1.3cm.

　　(3) Before grouting, the groove and both sides should be kept clean.

　　(4) The road surface temperature during construction should be maintained at 4 ℃, otherwise preheating should be carried out.

　　(5) Before opening up traffic, ensure that the sealant has sufficient cooling time
