| Popis: | 104 This experiment is for the secondary hardening chemical methods, the use of reverse engineering method from the etching→Grinding→Cutting pushed back the process to discuss the impact of all relevant factors secondary hardening. Process in the HF concentration because of etched glass and gradually decline, thereby affecting the etch rate, but itself if etching too long, will result in poor product appearance, and lack of etching the cracks can’t be eliminated or reduced, can not achieve the mechanical resistance to pressure increase purposes, If the glass cutting and grinding processes poorly, will produce a lot of> 100 um or more of crack extension (crack), because of the need to use the longer etching time, could have a substantial edge glass water ripples, resulting in poor appearance, If you choose to carry out high-density grinding wheel, reduce the degree of extension of cracks, may help repair two strong chemical effect, but the process is time consuming and costly, nor a mass productivity. Therefore, this study will be tested against the strengthening of the Management and control of secondary etching, grinding, cutting various conditions to 4PBT(4-Point Bending Test) analyze their respective conditions of AVG(Average) anti-stress and B10, to find the best conditions for strengthening. |
