To dry type composite film bubble, do that first

Dry compound, from time to time on the composite membrane can appear annoying bubbles, the reason is various, to dry composite film bubble trouble, do the following work: 1, to strengthen all kinds of raw materials ( Including film, all kinds of solvents, ink, adhesives, etc. ) Inspection work, strictly the quality pass, from the source to reduce composite film bubble and other failure risk, improve the quality of composite membrane. 2, in the actual production shall, according to the types and features of the different printing, film, packaging, after the performance of the contents and requirements as well as the processing conditions such as the specific circumstances to choose the appropriate printing ink and composite, by adhesives and adjust and control according to the specific production situation printing and composite process parameters, guarantee the quality of dry type composite membrane. 3, in the daily operation of equipment to take good care, and to pay attention to the maintenance of equipment and maintenance, timely cleaning before and after every time before driving and parking equipment, with dip with a small amount of solvent clean soft cloth rub-up adhesion on the surface of the applicator roll and rubber roller, adhesion agent or other debris and avoid these morohology dry solid effect after coating uniformity, thus reducing the incidence of bubbles. In addition, for the applicator roll also repeatedly with brush or copper brush to brush the net hole sections, as thoroughly as possible eliminate cave in net residual glue adhesion agent, lest cause net hole blockage, affect the amount of glue and glue evenness. Roller, coating in the preservation coating composite rubber roller, rubber roller and they shall be placed on a dedicated support, must not be allowed to directly on the ground, in case the restrict and affect the quality of the composite products. In addition, often should check if the roller was damaged, once found that damage to timely replacement or repair. 4, should make the environment temperature and humidity inside the printing shop remained relatively constant, conditional word can install air conditioning or wetted ( Humidifying) Such devices. Even at the same time keep the warehouse and workshop in environmental health, and good ventilation conditions, avoid dust, sand and other impurities foreign body of composite technology and dry composite membrane has a harmful effect on the quality.
