What is the rate of blasting?

Due to the existence of polished glass this objective phenomenon. According to statistics at home and abroad, the general situation every 4 tons of glass there is an example of "blew", into a conventional glass specific number, is the industry's 3 ‰ -5 ‰. From the engineering practice, the quality of the original film, the size of the glass layout, the control of the deep processing technology has a greater impact on the probability of blew.

The influence of the quality of the original film on the probability of blew is decisive. (1) The nickel-iron alloy linings used in the production of sand, furnish, fuel, and even crusher together determine the material base of nickel sulfide; (2) raw material management, melting and molding in the process of float production Process management, erosion of refractories, etc., determines the original glass of stones, bubbles and other impurities in the number. ③ Float production process in the cold end of the detection of impurities and treatment methods also determine the flow of deep processing plant to the original film quality.

The factors that affect the probability of blemish during deep processing are as follows: (1) the quality of the edge treatment; the microcracks at the edge of the glass directly affect the bleaching of the steel during the process. While the edge of the rough processing of the glass, there are also installed in the installation of the edge of the crack propagation and glass blew the situation. ② the higher the steel stress, the higher the probability of tempered glass blew.
