The high speed tape coating machine adopts special high speed coated head, which can effectively reduce the production of bubbles. All the coating rolls of the coating machine are all equipped with full speed automatic membrane mechanism and tension closed loop automatic control. Compared with the ordinary glue coating machine, it has its unique advantages. In the process of reverse roll coating, if the gap between two rolls is small and the capillary number is low enough, the flow in a relatively wide range of velocity ratio is relatively stable under a relatively small viscosity or speed, and a better coating apparent quality can be obtained. High speed tape coater is prone to air entrainment if the gap is relatively large and the coating speed is high. There are many tiny bubbles on the surface of the coating.
Adhesive coating machine is a green and environmental coating technology. It has fast production speed, high efficiency, low cost, small area of equipment and short investment recovery period. It is a economical and economical investment project. It has been widely used in packaging, medical * *, automobile, clothing, electronics and other industries. Hot melt adhesive coating has huge market prospects. The technology will develop more and more in the market and will continue to appear in new application fields.
