How to use water based pu adhesive to achieve maximum utilization
Water based pu adhesive because of its low cost and good environmental protection characteristics, generally does not emit VOCs during use, so there is no obvious harm to people and human bodies, especially water-based PU adhesive can better save Equipment, water-based PU adhesive has good adhesion properties.
So now water based pu adhesive is slowly being understood and accepted by people. At present, many shoe manufacturing industries also choose water based pu adhesive, but if the water-based PU adhesive is not used properly, it will easily cause pregnant products. So, what should be paid attention to when using water-based PU adhesive, and how to use it to achieve the best results.
First of all, pay attention to the correct use of spray guns. When using water-based PU glue, you need to pay attention to that. When using water-based PU glue spray guns, you must use special guns. Although they are all spray guns and work in a similar way, they are still quite different.
For example, the diameter of the paint spray gun is relatively small, because the paint is a low-viscosity liquid and the adhesion is not particularly strong, so it is easy to perform atomization. However, water-based PU glue has high adhesion before drying, and it is relatively difficult to atomize the spray gun. If a paint spray gun is used to atomize the water-based PU glue, it will be easy to block the nozzle of the spray gun, but not the spray gun. Normal use.
If the spray gun nozzle is found to be difficult to atomize during spraying, it needs to be cleaned in time, and it can not be used any more, so as not to affect the effect. It can be said that water-based PU glue will only be used if it is used correctly according to the instructions. Glue exerts its best effect, so be sure to pay more attention to these matters when using it.
