Plastic coated canvas often encounters high paste viscosity during production. If the quality of the equipment is not up to standard (mainly because the quality of the feeding roller is not up to standard), the roller will be twisted, and the coated cloth will easily cause the adhesive layer to be thin on both sides and thick in the middle. It is easy to crush the edge of the cloth, so it is necessary to improve the toughness of the roller; it is best to choose a solid alloy roller; but if the quality of the adhesive layer is too poor, it will stick to the feeding roller, so a knife hanger can be used, so there should be 2 plastic coating machines. Coating head, namely roller coating + knife coating.
If you do not want to change the equipment, you must reduce the viscosity of the material. Physical viscosity reducer or chemical viscosity reducer can be added. Chemical viscosity reducer is limited to reduce viscosity. If the amount of viscosity reduction is large, physical viscosity reducer is still used, but this will increase production costs.
Therefore, the best equipment modification is of great benefit to future production and operation, and can also reduce the pollution of waste gas to the environment. Therefore, when purchasing plastic coating machine equipment, we should pay attention to the quality of the equipment, not only the appearance of the equipment, but also the inherent quality of the equipment itself, otherwise the production cost will be high, and it will not survive.
