Laminating glue is currently a kind of strong glue widely used in the market, so what is the application processing process of laminating glue?
The application processing technology of laminating glue is as follows:
1, the composite method is dry composite, that is, the coating machine should use a dry composite machine with curing furnace and composite roller heating.
2, curing furnace ambient temperature of about 60-95 ℃. The ambient temperature of the compound working pressure roller is about 40-70 ℃, and the compound working pressure is about 8-20kg.
3, it is best under permitted conditions, the strong glue is baked to 7-9 dry is appropriate, in such an environment composite products color is relatively high, rapid speed. In such a compound environment, compound working pressure rollers.
4, for gold printing silver products or printing ink and gold and silver cardboard that are very easy to discolor reaction, the strong glue must be thoroughly dried.
The ambient temperature should be reduced to less than 50℃ to prevent the occurrence of large bubbles in composite products; The working pressure should be slightly reduced, and the most appropriate is that the strong glue is not squeezed.
5, in the selection of strong glue is completely dried processing process, the composite working pressure roller temperature in the case of not burning the film the higher the better, the greater the working pressure the better.
Common faults and treatment methods of water-based dry film adhesive (laminating adhesive)
Transport storage temperature shall not be lower than 5 degrees, pay attention to anti-freezing and sunscreen.
The machine must be cleaned before use;
Products generally can not be mixed with other glues;
When the machine stops, clean the rubber roller, scraping plate and groove in time;
All BOPP films must be corona qualified;
It is recommended to make a small sample before laminating gold and silver ink prints to confirm no color difference and bonding strength, and must wait until the glue is completely dry before pressing;
If the composite product has the following conditions or is processed after coating, a sample should be tested before mass production;
1.Gold and silver cardstock;
2. embossing;
3.concave and convex;
4.Paper hanging;
5.Printed matter with thick ink layer or large dry oil;
