Imitate cooling treatment.
Further, it is attributed to the inherent characteristic of coated glass original piece 13, when its thickness rises to 6mm by 5mm, pressure
The strong chilling wind for 4500Pa~5000Pa will make its interior tissue in cooling procedure when acting on it to be had obviously
Temperature gradient difference, and then the stress concentration phenomenon for causing it internal occurs, it at this time just must be for coated glass original piece 136mm's
Chilling wind pressure pressure is significantly reduced, and its pressure value range is set as 2000Pa~2500Pa by thickness.In this way, pressure
On the one hand coated glass original piece 13 that chilling wind for 2000Pa~2500Pa can be rapidly 6mm to thickness is quickly cooled down,
On the other hand it can avoid causing the internal temperature gradient of coated glass original piece 13 excessive and causing interior tissue inhomogenous again, stress
The serious phenomenon of concentration phenomenon occurs.So by being 2000Pa~2500Pa by the pressure set of chilling wind, just take into account in this way
To carry out effective temperature-reducing cooling and ensure coated glass original piece 13 that thickness is 6mm for the coated glass original piece 13 for being 6mm to thickness
Interior tissue is stablized in cooling procedure, reduces it and reveals risk.
