Benefit is that during interstitial structure is processed, the contact area of process equipment and the second glass cover-plate 40 will not be from the beginning of
When be exactly favorite it, it is then invariable, but start from scratch, i.e., process, arrive since an angle of the second glass cover-plate 40
It diagonally terminates, and the process velocity of broached-tooth design can be not in very big suddenly, the acute variation mistake then to diminish again with constant
Journey, the damage to process equipment are smaller.
In order to not change the thickness of component, ensure the built-in quality of component, the broached-tooth design layer and second glass
Cover plate 40 is integral type structure, i.e., it is to be obtained on existing second glass cover-plate 40 by processing that this, which changes broached-tooth design layer,
So that the thickness of the solar double-glass assemblies finally obtained and original solar double-glass assemblies is identical, other processing technologys of solar double-glass assemblies do not have
There is change.
