How to temper soft offline Low E glass by forced convection glass tempering furnace?

Actually, there is no standard for low-e glass because no one knows what the e-value of this glass is. First, you can check the e value.

Normally, when temper a new type Low-e glass, first, pls test one piece of this glass. Compared with normal float glass, the lower temperature is lowered a bit, the heating time is extended, and the convection fan is turned on larger.

After the glass is taken out of the furnace, first check whether there is white mist on the glass. If there is no white mist, it means that the convection fan is turned on basically. If there is a white mist below, it means that the convection fan is turned on too small. If there are two white mists, it means that the convection fan is turned on too large.

Next, focus on heating up the time. If it breaks, it means the time is short. If there is some wave, it means the time is long. In addition, the wind pressure on the upper part of Lowe glass is slightly higher than that of ordinary glass, which can be adjusted based on the fragmentation and flatness.

The flatness adjustment method is the same as ordinary. The principle is that there are no standard parameters, they are all tested one by one and then recorded for future use.
