Problems solved by technology

On the surface, this method seems to make the fan smaller, but because of the addition of the quenching section (about 2000mm in length), the total cost of the equipment has not been reduced. The glass is easily bent when
At the same time, the thinner the glass that needs to be tempered in the existing process, the higher the wind pressure of the fan is required, which also limits the tempering of ultra-thin glass with a thickness less than 3mm

Embodiment Construction

[0017] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0018] Such as figure 2 As shown, the processing of tempered glass is mainly divided into two steps: the glass 1 enters the heating chamber 2 from the loading table, and is heated on the reciprocating ceramic roller table 3 until it reaches a temperature suitable for tempering (due to the original glass plate used by each manufacturer) Different, the softening point is different, the color is different, the thickness error is different, and the heating time is different. If the glass is broken in the quenching section, it means that the heating time is not enough. If there are ribs and pits on the glass surface, it means that the heating time is too long, so The heating time in actual production should be adjusted accordingly according to specific conditions); the heated glass 1 enters the cooling chamber 4 for quenching (the glass 1 is blown on the reciprocati...

Abstract

The invention discloses an air grid. The air grid comprises an air grid body with a blowing board, wherein an air blowing hole is formed in the blowing board; and an aperture D of the air blowing hole is 3mm to 5.5mm, a distance between two adjacent air blowing holes in a same row is 10mm to 25mm, and a distance M between two adjacent rows of air blowing holes is 10mm to 18mm. The low-pressure quenching process of the tempered glass is as follows: a quenching air grid of a cooling section adopts the structure of the air grid, and an air pressure value when in quenching is 50 to 60 percent of a theoretical air pressure value. The inventor team discovers that the air pressure of a fan when in quenching can be reduced if the ratio between the real area and an air blowing area of the air grid is reasonably adjusted by virtue of analysis, experiment and improvement. The further research discovers that when the aperture and distance of the air blowing hole of the air grid are adjusted to a required protection range, the real air pressure value of the fan when the glass is tempered can be decreased to be less than 60 percent of the theoretical value.

Description

technical field [0001] The invention relates to a tempered glass processing technology, in particular to an air grid, and also relates to a low-pressure quenching process when the air grid tempered glass with the structure is adopted. Background technique [0002] Tempered glass refers to glass that forms a compressive stress layer on the glass surface after reprocessing. Tempered glass has been widely used, from the earliest aviation field to construction, automobile industry, transportation, electronics, chemical industry, medical treatment, printing and other fields. There are many methods of tempering glass, which are usually divided into two categories: physical tempering method and chemical tempering method. The physical tempering process can be divided into air-cooled tempering method, liquid-cooled tempering method, particle tempering method and spray tempering method according to the quenching medium. The advantages of the air-cooled tempering method are lower cos...
