Gray glass production technology gray glass (Figure 5-10), also known as neutral gray glass glass, which is characterized by a balanced transmittance over the entire visible spectrum, and therefore its spectral curve is almost through with the abscissa axion line, but no glass shades. Ideal neutral glass does not actually exist, gray filter photometric precision is very close to neutral with glass. Manufacturing was darkened gray discoloration of the ingredients can be used to darken the glass was tinted glass matrix. These components are described in British Patent No. 1,515,642 in Pat. These advertisements already known fast response glass color glass, internal distribution of halides: silver grains discoloration aluminophosphate glass. Non-color components of the glass (weight 96) as follows - 'SiO:! 8.5-25: 6, Al. O. 13-56.5%, P: O. The .5-33.5: "color glass manufacturers, B: O. 7-28%, R: O7-20.5%. ; Its towel R. O represents Na. O, K: O and li: O in one or more of · oxide. Li: O is the highest content of 5%, when BzO, avian less than 896 color development performance impact when carried out final heat treatment at the annealing point of the high between 20 ℃ and 100 ℃, for 10-60 minutes completed within the period. For specific glass, optimum annealing temperature gradient furnace techniques to determine the available range. Sometimes, in order to avoid deformation during the heat treatment, the need to support the glass mat. Glass melting furnace charge can be an ordinary glass material preparation: such as carbonates, phosphates or partial positive phosphates, nitrates and oxides. Or silver halide composition, silver may be ground respectively and sodium halide or potassium halide is added in the form of charge. During melting, evaporation losses in order to minimize the burden components, the need to take protective measures. Hot tempered glass surface: Reason: 1. Hot glass surface is dense shape hesperidin, which is due to the surface temperature of the glass after baking is too high or the heating time is too long leads. Solution: Reduce the oven temperature to make thick glass, so that, under the furnace before entering the furnace temperature. Under the circumstances, does not affect the quality of the glass, to reduce the heating time. Reasons: 1. If overheated, showing a star-shaped glass, which is normal because the new furnace at the production stage or ceramic roller sediment / original plate glass itself is not clean. Solution: revocation of the original plate roller furnace dirty things, waste board outside the dirt on the glass to check into the furnace, reducing the speed of the glass in the furnace back and forth. ● glass plate deformation Reason 1: The intermediate glass concave peripheral upturned, peripheral portion on the surface temperature is too high, more center low temperature shrinkage, less shrinkage. Solution: Adjust the temperature of the furnace on the poor, open homogenization furnace heat balance. Cause 2: glass around the intermediate drum recurved discoloration glass advertising, the lower surface of the surrounding temperature is less than the central high shrinkage low shrink temperature. Solution: a lower adjustment, in an oven, open the heating furnace temperature balance homogenization temperature difference.
