4. User Guide
1. Before filling, ensure that the cracks are dry and there is no water or rain within 24 hours before and after potting.
2, according to customer requirements, whether to slotting and filling. The dust must be purged before potting.
3. When the temperature during the construction of the joint is lower than 5 °C, the crack should be preheated by a hot spray gun.
4. The filling joint is constructed by a filling machine with a stirring function. The sealing glue should be continuously stirred during the construction process. The sealing glue needs to be heated to 180-190 °C before the filling can be applied.
5, After the construction of the joint, it should be allowed to stand for 20 minutes to open the traffic. If it is open traffic immediately, it needs to sprinkle a small amount of fine sand or talcum powder, cement and other spacers to prevent the glue from sticking to the tire.
6. After the filling construction is completed, the sealing machine should be cleaned and the sealant should be avoided in the filling machine. After each section of the jointing construction, the filling machine should be cleaned.
