China is already the world Bopp touch film output power

Bopp touch membrane production technology in 1958 by Italian Katie company initiative. Industrialize production in Europe and the United States and Japan monopoly in 1962, since its rapid development, currently the world's more than 200 production enterprises, nearly 500 production lines. In our country since the early 60 s by Beijing chemical industry research institute and other units for design and manufacture of two-way stretch technology and equipment, and completed and put into operation in succession some smaller, simple equipment production line, and so far, our country is already the world film Bopp tactility output power, has brought new changes in the supply and demand in China and even Asia.

how to ensure the precoating touch film laminating temperature uniform at work?

when using membrane tectorial pre-coating tactility, to ensure the effect of the effect is good, generally in the process of work to keep the effect of temperature, such coated effect will be better.

so, how to guarantee the precoating tactility film laminating temperature in work?

in order to ensure the quality of composite, it is necessary to make the specification of laminating temperature data in the whole work process has always been consistent.

(1) the use of electronic, mercury thermometer, such as measuring the temperature of the heating roller surface of different positions, pay attention to each part of the heating roller surface temperature difference and the instrument shows the difference in temperature, through appropriate adjustment, control the lower limit of the actual temperature, limit within the specification data:

2. As far as possible the heating roller electric, air, heating roller transmission structure and transformed into electric heating, heat conduction oil, heating roller transmission structure. Depend on the characteristics of heat conduction oil medium, maintain a constant heating platen temperature. In work interface area effectively absorb heating roller heat conduction. Ensure hot melt colloid fully melted.

display colloid full fusion is an important symbol of good transparency, it is the most intuitive and convenient testing method.
