First, Frosted glass Frosted tempered glass (frosted glass) is a homogeneous rough surface with sandblast glass or hydrofluoric acid etching glass is formed. Frosting technology can also be combined with screen printing technology to produce a variety of different patterns and designs on the glass surface for decoration, produce hazy, noble, elegant decorative effect. Frosted glass and steel-sided, we need to put into the furnace Frosted face up to avoid damage to the roller. Since Frosting surface is matte, to heat absorption enhancement, Frosted glass surface temperature rises quickly, the production time, to set the upper temperature lower than the lower part, holding the furnace temperature uniformity. In addition, quenching the windward gate height slightly lower, but also help produce high-quality glass Frosting. Frosted glass and steel double-sided, glass will have some friction roller damage, it should be avoided producing double-sided Frosted glass. If you really need to produce, it can adjust the line speed of the glass movement is small, and 5% to 10% shorter heating time. After production, with waste glass (must be clean) friction dressing roller. 2.2 Measures for controlling thermal deformation temperature unevenness due to heating caused by (1) the temperature difference for the upper and lower surfaces, when the glass is bent upward, indicating that the glass surface temperature. Surface temperature should be reduced, while maintaining the overall glass heating temperature constant, an appropriate increase in surface temperature; when the glass is bent downward, indicating that the surface temperature is higher than the surface temperature, the surface temperature should be lower due to lower, while increasing the surface temperature. If at the time of adjusting the temperature, tempered steel yield and quality are affected, respectively, an appropriate extension of the heating time or reduce the heating time. (2) For the deformation temperature difference caused by the presence of glass in the middle and edge, if the glass showing saddle-shaped, indicating poor insulation or furnace temperature setpoint lower edge, you need to adjust the temperature set point edge; when When the glass bottom of the pot shape rendering, if due to historical reasons, can temporarily laying glass, the first air furnace operation, the furnace temperature is evenly distributed and then poorly; if the temperature setting issue, the need to adjust the temperature setting parameters, so furnace temperature distribution. (3) for the random uneven temperature, you need timely maintenance equipment, to avoid adverse device status, often to clean up broken glass near the temperature sensor, the temperature sensor is accurate to feel the temperature of the furnace, while the topsheet is to avoid more furnace in the same state stacked.
