Determination of melting temperature
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 temperature 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.
Avoid long time high temperature heating coatings
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.
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 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. When the raw material is started, the engine should not be started, the residual material 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 is started. The mixing device has positive or negative speed or agitation at a fast and slow speed, adjusting according to the actual situation.
In the melting process, the hot-melt kettle should adjust the fire size in time according to the speed of marking 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.
