Embodiment Construction
[0011] A touch screen cover glass with strong acid and alkali resistance, the components in the glass components are calculated by weight percentage as follows:
[0012] SiO 2 55-67%,
[0013] Al 2 o 3 16-24%,
[0014] Na 2 O 13-18%,
[0015] ZnO 0.1-4%,
[0016] TiO 2 0.1-1%.
[0017] The SiO 2 The content is preferably 60-63%.
[0018] The Al 2 o 3 The content is preferably 18-22%.
[0019] The Na 2 The O content is preferably 14-17%.
[0020] The ZnO content is preferably 0.5-3.5%.
[0021] The TiO 2 The content is preferably 0.5-0.8%.
[0022] SiO 2 It is a component that constitutes the glass skeleton, SiO 2 Higher content, chemical resistance and mechanical strength will increase, high temperature viscosity of glass will increase, SiO 2 If it is too much, it will be difficult to obtain glass with long material properties. SiO 2 Low content is not easy to form glass, the strain point decreases, the expansion coefficient increases, th...
