The laminating machine has high requirements for temperature control. If the temperature is too high, the heating time is too long, and the film quality will decrease. If the drying temperature is too high, the surface of the adhesive will be skinned, resulting in blistering of the film.

Excessive thermal stress will also cause the film to lose its elasticity, resulting in performance degradation and easy tearing. There are three ways to dissipate heat in physics:

Conduction, convection and radiation, the first two have been eliminated, that can only be solved by thermal radiation. Radiation heat dissipation can not be affected by the temperature of the medium surrounding the object. As long as the temperature of the object exceeds zero, the object will radiate heat, but it depends solely on the object itself. The heat radiation amount of the object is very small, and it cannot solve the heat dissipation and cooling of the object well. Only increase the heat radiation amount of the object to reduce the temperature of the object, so that a layer of heat dissipation paint is applied on the surface of the object to greatly enhance the heat of the object. The amount of radiation to reduce the temperature of the object.

The heat dissipation coating improves heat exchange in the form of infrared radiation, and the heat dissipation is not affected by the surrounding medium. The heat dissipation of the coating can be used in a vacuum environment. The radiant heat dissipation cooling coating can improve heat exchange while also having good self-cleaning properties. Features of insulation, corrosion resistance, water resistance, acid and alkali resistance, and convenient construction.

Laminating machines can be divided into two categories: instant-coating laminating machines and pre-coating laminating machines. It is a kind of special equipment for paper, board, and film laminating. After being pressurized by rubber roller and heating roller, they are combined together to form a paper-plastic product. Now let's talk about what to do when the laminating machine foams. If the printing ink layer is not dry, it should be hot-pressed and glued again to delay the coating time to make it dry. The printing ink layer is too thick. Should increase the amount of adhesive coating, increase the pressure and compound temperature. If the drying temperature is too high, the surface of the adhesive will crust, so the drying temperature should be lowered.

The surface temperature of the composite roller is too high, so the temperature of the composite roller should be lowered. The film of the laminating machine is wrinkled or slack, the film is uneven or curled, the film should be replaced and the tension adjusted. There are dust and impurities on the surface of the film, which should be cleaned up in time. Adhesive coating is not uniform and the amount is small, so the coating amount and uniformity should be increased. If the binder concentration is too high, the viscosity is high, and the coating is uneven, the thinner should be used to reduce the binder concentration.
