The laminating machine has a bad situation of sticking to the table
There is a bad situation of sticking to the table
(1) Improper selection of adhesive, improper setting of glue application amount, and wrong ratio measurement. The type and amount of adhesive should be re-selected.
(2) The diluent contains alcohol and water that consume NCO groups, so that the main agent does not react. High purity CH3COOC2H5 should be used.
(3) There is powder spraying on the surface of the printed matter. Wipe off gently with a dry cloth.
(4) The ink layer of the printed matter is too thick. Adhesive coating arrangement should be increased to increase pressure
(5) The ink layer of the printed matter is not dry or completely dry. It should be hot pressed once before gluing; choose an adhesive with a high solid content; increase the coating thickness of the adhesive; increase the temperature of the drying path, etc.
(6) The adhesive is absorbed by printing ink and paper, so that the amount of coating is insufficient. Reformulation and application rates should be set.
(7) The surface treatment of the plastic film is not enough or exceeds the pot life, making the treated surface invalid. The plastic film should be replaced.
(8) The pressure is low, the vehicle speed is fast, and the temperature is low. The temperature and pressure of the film should be increased, and the speed of the vehicle should be appropriately reduced.
