UVLED technology has the advantages of fast curing speed, energy saving and environmental protection. Quickly promoted in the printing and coating industries, occupying a large market, and has not made much progress in the glass printing industry. With the efforts of various professional ink manufacturers and the active cooperation of glass processing enterprises, UVLED technology The application has made breakthrough progress. It is advancing towards the stage of industrialization development. In the near future, UVLED printing will become the main production method of the glass printing industry. This is because the development requirements of the low-carbon economy are a global trend. From the perspective of low-carbon emission reduction and environmental protection, glass printing technology must meet the production technology methods of environmental protection requirements. From the current point of view, UVLED printing technology meets the requirements of low-carbon environmental protection, this revolution is imperative.

For a long time, the glass printing industry has focused on self-drying and thermosetting inks. Although the self-drying ink is energy-saving, the various indicators cannot fully meet the requirements of the product. The thermosetting ink has good various indicators, but the processing process consumes a lot of power. Slow curing speed (relative to UVLED printing), does not meet the requirements of low carbon and environmental protection! Thermosetting inks have one-component and two-component (two-component with curing agent) but all need to be baked at 150-180 degrees for 8-25 minutes to dry. In contrast, UVLED technology has great potential, and will definitely replace traditional curing systems such as ovens in the future.

Compared with the cost of traditional color crystal glass printing:

1. Investment in printing workshop (taking investment of 1 tunnel and 2 screen printing machines as an example) The printing room needs about 1500 square meters, 1500 × 15 yuan / square meter (market price) = 22500 yuan (factory rent)

2. Electricity fee, tunnel electricity fee, 60kw × 8h = 480kw (working 8 hours per day)

Glass size (47 × 636cm refrigerator glass size as an example), printed 400 times per hour to calculate. 0.47 × 0.63 (glass size) × 2 (2 machines) × 400 × 8h = 1895 ÷ 3 (printing times per glass) The daily output is about (finished product 630 square meters) 480KW ÷ 630 square = 0.78 degrees / square 12480 × 0.9 yuan = 11232 yuan (monthly electricity bill)

3. The market price of colored ink is between 55-75 yuan. The color crystal ink is about 90-130 yuan, which can be printed 25 square meters per kilogram. Each glass is printed three times (both mirror silver, color crystal, cover bottom). The cost per square meter is about 5.8-8.5 (the cost is normal printing meter). When the screen printing plate or the two-component ink loss, it should rise 20-30%, which is about 7.5 yuan -11.5 yuan).

The development of energy-saving and efficient UVLED technology has opened up a brand new path for the glass printing industry.
