1.The traditional gas heating mode, heating the pouring material directly, easy to burn materials, uneven heating,Road Cutting Machine and open-air operations, easily lead to high-temperature to the gas tank , flammable and explosive easily, there is a big security risk .
2. Heating mode of heat transfer oil, the heat transfer oil as heat conduction, heating the material indirectly,rubberized hot melt asphalt driveway crack adhesive sealant the heating function is slow, uneven heating, ans little pressure during sprinkler .After heated the heat transfer oil to high temperature it will expand and have serious consequences if the exhaust vent is blocked.
3.Power exhaust heating and screw extruder way.
Scope and works of hot asphalt sealing machineRoad crack is one of the most common diseases of asphalt pavement irregular cracks, expansion joints of concrete pavement. if not potting timely,Saving Asphalt Mixing Plant Application it will cause a large area of the road surface damage. Hot asphalt sealing machine is used to melt the material and pouring material into the cracks to achieve the special equipment of payment maintenance.
The heat sealing machine asphalt used the liquefied gas as fuel, heating on the bottom of the pouring tank . HTF filled inner tank wall make heating quickly and heating average, insulation plays the role of an warm keeper out of HTF wool insulation. After the sealant melt,Refractory Concrete Pavement Humidifier it can be used by manual mixed to exchange the heat. After the sealant achieve the requirement , the pump will start pouring asphalt material output, manual forward (or backward) to the discharge port aligned cracks, promote equipment to sealing.
