    determination of melting temperature
    determination of melting temperature
    coating temperature should be determined according to the construction environment and the melting point of coating itself. If the local temperature is lower, the coating temperature can be appropriately higher, and vice versa; when the coating is thicker, or when the construction machinery is running slowly, the material temperature can be lower. The temperature of the coatings of different manufacturers is not the same. You should pay attention to the instructions.
    The paint temperature should be determined according to the construction environment and the melting point of the paint itself.If the temperature of the ground gas is low, the temperature of the coating can be properly higher, and vice versa; the construction coating is thicker, or the temper Ature of the construction machinery is lower when the driving speed is slower.The temperature of the coatings of different manufacturers is not the same.You should pay attention to the instructions. If the marking construction is stopped for some reason, the furnace fire of the hot melting kettle should be reduced in order to prevent the coating from being too thin or discolored for a long time.
    If the marking construction is stopped for some reason, the fire of the hot-melt kettle should be reduced, so as to prevent the heating of the paint from overheating for a long time, and the paint is too thin or discolourable, which will affect the construction.
    Different kinds of Try not to mix up different kinds of hot-melt coatings
    The cover of the hot-melt kettle should be kept open at the initial heating stage. If br /> is not opened, the heated vapor in the hot-melt kettle may ignite more often, and when the feeder suddenly opens, the gas in the kettle leaks out, possibly burning the worker. The engine should not start when the initial melt is started. When the residual material in the kettle is melted and the stirring blade can be easily propelled, the engine should be started again, and the hydraulic or mechanical stirring switch should be put on to start the stirring. The mixing device has positive or negative speed or agitation at a fast and slow speed, adjusting according to the actual situation.
    If it is not open, the steam heated by the hot-melt kettle may catch fire when the heat is gathered. When the feeding worker suddenly opens it, the gas in the kettle is released, and the workers may be burned. Erial in the kettle will be melted away.When the blade can be easily propelled, the diesel engine will be restarted, and the hydraulic or mechanical mixing switch is carried on, and the stirring device is started.The mixing device has positive or negative speed or agitation at a fast and slow speed, adj. The hot-melt kettle should adjust the fire size in time to the speed of marking construction. Contrarily, the smaller point. The size of the fire is reasonably adjusted in order to ensure the progress of the marking machine construction.
    When the paint is thicker, the fire can be larger, otherwise the dots will be smaller. The size of the fire is reasonably adjusted in order to ensure the progress of the marking machine construction.
