Pavement curing equipment - filling machine, mainly used in pavement crack prevention conservation. Longrui machinery, road filling machine The device's sealant hot melt kettle with multi-layer design (inner diameter - thermal insulation layer - insulation layer --- shell), the burner heating the heat transfer oil, heat transfer oil on the hot melt for the whole heating, so that the sealant is not easy to aging, But also to ensure the temperature uniformity. Heat conduction oil heating hose conveyor system, the thermal oil and hot melt kettle thermal oil is the same heating system, both effective in the hose and hot melt within the sealant temperature exactly the same, to avoid the pipeline sealant back, Cleaning, hoses baking trouble, but also to ensure that the sealant pipe flow at any time and not blocked. This product of the thermal oil heating hose and the electric heating pipe compared to the tube sealant even more uniform and should not be aging, and save time and other advantages. The heating hose is made of double-layer casing design and two seals. The die is made of aviation metal material, and the high temperature Teflon fabric is lining, and the electric heating hose is more reliable and the heating time is shorter. Longer life and other advantages (electric heating hose should occur short circuit or break caused by hose blockage). The hose with an insurance operating lever and shoulder strap, not only make the operating surface clean, beautiful, and continuous operation light and not tired. Conservation. After sealing with the sealant, the sealant is fully cooled and the slag on the road is cleaned to open the traffic. The general cooling time is about 15 minutes. The specific open traffic time can be controlled according to the temperature. After several years of irrigation practice proved that the main performance of the filling machine failure is the sealant and cracks in the two walls can not be firmly bonded, mainly with the sealant technical performance, clear trough is completely and the construction of the ambient temperature, Therefore, it is very important to choose the seal of the construction season and suitable for the local construction environment. trailer asphalt heater wholesalers types of construction vehicles names intelligent asphalt distributor manufacturers reactivation and regeneration of activated carbon
