Spiral steel pipe anti-corrosion coating performance mainly has the impact resistance, flexural properties, wear resistance. On the impact asphalt companies near me strength, the twist with polyethylene plastic coating is better than the asphalt coating, and a good protective layer of polyethylene plastic rigid polyurethane foam coating toughness, which has good resistance to bending properties, but smaller mechanical strength, can not withstand the beat, hit, so pay attention gently, avoid collisions and reduce damage when loading and unloading. into heat-resistant coating temperature resistance and low temperature parking lot striping resistance, which is to determine the boundaries of the main transport medium temperature parameters, to ensure that the use of heat resistance temperature deformation, not flowing, do not accelerate the rate of aging, and the softening point related the low temperature to ensure that it stacked at low temperatures, transport and construction pull no cracks, no shedding. Asphalt coating temperature performance is poor, piped medium temperature does not exceed 80 , heat-resistant coating of polyethylene plastic twist with a certain degree depending on the heat-resistant primer, if primer poor temperature resistance, adhesion performance is poor, the upper limit is quite petroleum asphalt coating, foam, rigid polyurethane foam coating as a good insulation […]
