Along with the people environmental protection consciousness enhancement, furniture factory has begun to transition choice instead of waterborne wood paint paint, including waterborne wood paint drying is a must to solve the problem, what circumstance waterborne wood paint dries quickly, waterborne wood coatings how fast drying method!
Underneath, small make up about several common methods of drying for you!
1, the natural drying
natural drying method is simple and applied widely, but at the same time with slow drying defects. In the temperature and humidity and wind speed is changing from time to time, drying speed and film quality is not stable. Under high temperature and high humidity or high humidity conditions, paint film is easy to pale. Especially in the low temperature below 5 ℃, waterborne wood paint film.
2, microwave drying,
microwave refers to the electromagnetic wave, with a penetrating common frequency is 915 - 2450 mhz。 The application of microwave heating is a principle of dielectric loss, make the rapid oscillating water molecules, the heating effect of the significant, so that the wood lacquer interior and exterior temperature meteoric rise at the same time. The advantages of microwave heating is particularly fast drying speed, by drying objects without appearance requirement, heating, on average, there is no temperature gradient.
3, hot air drying
the hot air drying is the principle of convection, in a temperature of 40 ~ 60 ℃ hot air for heating medium, to send objects appearance of coatings, heat energy absorption after curing film heating drying method. Hot air drying process, can significantly speed up the coating is dry, and has the characteristics of strong adaptability, is a kind of dry application of common way.
4, infrared drying
infrared curing waterborne wood paint are can be used to dry. Infrared ray is a kind of invisible rays, between the visible and microwave, the wavelength of 0. 72 - 1000um。 Infrared curing with rapid, curing speed and temperature as well as good quality, but dry coating obvious temperature gradient, should not be used for the drying of the thicker coating.
