[China Glass Net] When the glass is cooled in the air-cooled section, the distance between the wind grid and the glass will affect the wind pressure applied to the glass surface. When the wind pressure at the time of blowing is constant, between the wind grid and the glass The pitch of the glass becomes smaller, the wind pressure applied to the surface of the glass will increase relatively, and the number of pieces, mechanical strength and safety performance will be improved; conversely, if the distance between the wind grid and the glass is increased, it is applied to the surface of the glass. The wind pressure will be relatively reduced. After the glass tempering, the surface will obtain less stress, and the number of fragments, mechanical strength and safety performance will be relatively poor. When the wind pressure during tempering is constant, the wind can be adjusted to some extent. The distance between the grid and the glass is used to adjust the quality of the tempered glass, but the distance between the wind grid and the glass cannot be lowered. If the distance is too small, the stress spots on the surface of the glass after tempering will increase.
