The development of modern industry presents a multifunctional character, many enterprises have been affected by the introduction of advanced production equipment. Hot melt Adhesive coating machine as a technology-based product, has also gained a better development trend in the market. It is different from the traditional foam coating machine, in the efficacy of high efficiency and fast air-drying, to a certain extent, for the production of good yield preparation. So for such a multi-functional machinery and equipment, how should we use to better play its role?

The use of hot melt adhesive coater first of all we should timely replenish the amount of glue, and when appropriate, should also improve the amount of glue. This is because the amount of glue is too small will lead to a reduction in the degree of adhesion, and ultimately produce difficult to compound the results. We can use anilox rollers with deeper anilox holes, or increase the amount of glue applied to the surface of the substrate through the pressure of the rubber rollers and reducing the contact pressure between the doctor blade and the anilox rollers. For some plastic film substrates, you can corona treatment before coating, so that the surface of the hairy Whipple, thus improving the ability of the substrate to adsorb adhesive, so that the amount of adhesive coated on the surface of the increase.

Secondly, in the choice of drying temperature should also pay special attention. Only full grasp of the drying temperature, in order to bring good performance for the use of hot melt adhesive coating machine, the temperature is too high or too low will affect the adhesive fastness of the composite film.

Coated substrate drying temperature is too high or after high-temperature cooking, will make the surface layer of the adhesive is carbonised, thus destroying the adhesive bonding ability. Drying temperature is too low, the adhesive curing is not complete, the adhesive viscosity of the adhesive is poor, the composite is not firm and after a period of time, the composite film is easy to form bubbles, destroying the composite quality of the product.
