Water based varnish in the correct storage environment is a kind of non conjunctival information, just like edible oil in the air will not form a dry film. See ultraviolet light, such as sunlight, arc welding, printing lamp will immediately cure. But general fluorescent lamps, incandescent lamps and other lighting sources will not cause water-based varnish curing. The photoinitiators and diluents in water-based varnish have a certain stimulating effect on human skin. The following varnish machine manufacturers for you to introduce the high gloss oil preservation method.

 

Taking into account the characteristics of water-based varnish, in the use of water-based varnish should pay attention to the following points:

 

1. When passing through the UV lamp irradiation area, the better temperature should be 50 ~ 60 ℃, because the waterborne Varnish can cure quickly at this temperature and has strong adhesion after curing. That is to say, under the UV lamp, the lower the temperature is, the better. Some manufacturers in winter low temperature factory glazing, adhesion is not good, leveling is not good, the main reason is that.

 

2. Glazing machine should be placed in the sun can not be directly exposed to the position, otherwise water-based glazing oil will be in the sun under the effect of UV curing in the coating roll. If you can't avoid direct sunlight, you should also use red and black curtains to block the sunlight.

 

3. The normal operating temperature of water-based varnish is 50 ~ 55 ° C. when it is used at low temperature in winter, it needs constant temperature water to heat the water-based varnish circularly to make its viscosity reach the planned operating viscosity, which is conducive to the smooth and rapid solidification of water-based varnish.

 

4. When polishing, the water-based varnish scraped off will bring the ink that has been printed on the substrate to the water-based varnish on the polishing machine to make the varnish color. However, after filtering deposition, these glazing oil can continue to use, do not have to throw away.

 

5. The viscosity of water-based glazing oil varies according to the type of glazing machine. Special glazing oil should be selected according to the type of glazing machine. If the viscosity of water-based glazing oil can not reach the required viscosity of glazing machine, thinner can be used to remove or thickener can be used to add viscosity. But after such adjustment, the curing speed, brightness and adhesion of water-based varnish will be lost.
