Problems solved by technology

However, it is not easy to spray liquid and form a film with a glass anti-mold spraying machine alone, and the spray volume is large, and the film is not easy to clean after a long period of storage, which directly affects the appearance quality and deep processing of the glass.

example 1

[0045] Taking the glass melting volume of 200t / d, the original glass plate width of 4 meters, and the glass thickness of 5 mm as an example, the rear running speed of the glass production line is about 166.67 meters per hour. Mildew treatment, the operation steps are as follows:

[0046] 1) On the flat glass production line, install an anti-mold liquid spraying machine from the edge-cut glass. The outlet pressure of the hydraulic pump is 0.25 MPa, and the pump output is 2 liters / min; Rare earth chloride salt; Hydroxycarboxylic acids select lactic acid 5% for use in this example, and rare earth chloride salt selects cerium chloride 1% for use, and all the other are water;

[0047] 2) The distance between the anti-mold liquid spraying machine, the disk brush and the roller brush is 20 cm each; the flat glass sprayed with the anti-mold liquid has been successively washed by two disk brushes and two roller brushes to make the surface of the flat glass Completely soak in a thin la...

example 2

[0054] Taking the glass melting capacity of 800t / d, the original glass plate width of 5.2 meters, and the glass thickness of 5 mm, the rear running speed of the glass production line is about 513 meters per hour. Anti-mildew treatment is carried out on the surface of the cut and edged flat glass. The operation steps are basically the same as in Example 1, the difference lies in:

[0055] 1) The outlet pressure of the hydraulic pump in the anti-mold liquid spraying machine is 0.28 MPa, and the pump output is 8 liters / minute; the anti-mold liquid is selected from hydrochloric acid;

[0056] 2) The distance between the anti-mold liquid spraying machine, two disc brushes and two roller brushes is 25 cm each; the flat glass completely soaked in the anti-mold liquid, after standing for 2 to 10 minutes, the anti-mold liquid and the glass surface are fully Contact, and make the K, Na and other alkali metal ions in the upper and lower surfaces of the glass and the rare earth ions in th...

example 3

[0061] Taking the glass melting capacity of 1000t / d, the original glass plate width of 4 meters, and the glass thickness of 5 mm as an example, the downstream running speed of the glass production line is about 833.33 m / h. The operation steps are basically the same as in Example 1, the difference lies in:

[0062] 1) The outlet pressure of the hydraulic pump in the anti-mold liquid spraying machine is 0.30 MPa, and the pump output is 10 liters / minute; the anti-mold liquid used is composed of hydroxypropionic acid, hydrochloric acid, citric acid, chlorinated The mixture of cerium chloride and neodymium chloride in rare earth salt, the ratio of each component is: 10% of hydroxypropionic acid; 8% of hydrochloric acid; 6% of citric acid; 3% of cerium chloride; 4% of neodymium chloride %, the rest is water;

[0063]2) The anti-mold liquid spraying machine, the two disc brushes and the two roller brushes are each set at a distance of 30 cm, and are completely immersed in the anti-m...

Abstract

The invention discloses a mildew-proof treatment method for flat glass, which is realized through an operation process of a glass roller bed and comprises the following steps of: (1) spraying a mildew-proof solution to the flat glass subjected to cutting and edge breaking-off; (2) sequentially washing the flat glass sprayed with the mildew-proof solution in the step (1) by a disk brush and a roller bush, then, immersing the flag glass in the mildew-proof solution completely, and standing for 2-10min; (3) delivering the flat glass immersed with the mildew-proof solution in the step (2) into sponge compression rollers so as to squeeze away the mildew-proof solution on the surface of the flat glass; (4) carrying out jet-cleaning on the flat glass coming out from the sponge compression rollers by using a high-pressure water pipe; and (5) airing the cleaned flat glass through a high-pressure air knife finally. The treated flat glass has bright and clean surfaces and prolonged mildew-proof period; the mildew-proof solution used in the method is recyclable, and the mildew-proof treatment process is fully closed so that no liquid sputters and the treatment cost is reduced; and the method is suitable for the traditional glass roller bed and is easy to popularize and apply.

Description

technical field [0001] The invention relates to a mildew-proof treatment method for flat glass. Background technique [0002] During the storage and transportation of flat glass, due to the contact between the glass surface and the atmosphere, under certain temperature and humidity conditions, ion exchange and network structure disintegration are formed, and moldy spots are formed on the glass surface, that is, glass mold. The transparency and strength of the molded glass are greatly reduced, and the appearance deteriorates, which directly affects the quality of the glass. In severe cases, it will be scrapped due to adhesion, causing serious economic losses. Relying on the existing glass anti-mold technology, the anti-mold period of glass is only 1 to 4 months. In order to solve the problem of moldy glass, spraying anti-mildew liquid on the glass surface is a simple and effective method. However, it is not easy to spray liquid and form a film with a glass anti-mold sprayin...
