Problems solved by technology
[0003] At present, it is generally used to spray anti-mold isolation powder or anti-mold liquid on the surface of flat glass to protect the flat glass. The protection mechanism of the anti-mold liquid method is to treat the glass surface with an acid solution to make the glass surface acidic and neutralize it to cause mildew. basic groups, but most anti-mildew solutions are strongly acidic, which is not friendly to the environment, and strong acid waste water is easy to cause pollution

Embodiment Construction
[0019] In order to further understand the content of the invention, features and effects of the present invention, the following examples are listed below for illustration.
[0020] The present embodiment is a preferred embodiment, and its components and proportioning amount (parts by weight) are: sodium citrate 35, citric acid 6, ethanolamine 10, aluminum sulfate 1.5, surfactant 1, defoamer 0.2, and the remaining The volume is deionized water.
[0021] preparation:
[0022] 1. Take an appropriate amount of deionized water and heat it to 60°C, add surfactant, stir for 10 minutes, make the stirring evenly and maintain the solution temperature at 60°C, then add defoamer 0.2, stir for 10 minutes;
[0023] 2. Take an appropriate amount of deionized water, add sodium citrate, stir for 15 minutes to fully dissolve, then add aluminum sulfate and citric acid, stir for 10 minutes, and heat to 60°C;
[0024] 3. After heating ethanolamine to 60°C, add ethanolamine to the solution obtai...

The present invention discloses new glass anti-mildew liquid, which comprises the following components in parts by weight: 25-40 parts of sodium citrate, 5-10 parts of organic weak acid, 5-10 parts ofethanolamine, 0.4-2 parts of aluminum sulfate, 0.6-2 parts of a surfactant, 0.1-1 part of a defoamer, and 35-60 parts of deionized water. By optimizing the composition of a formula of the glass anti-mildew liquid, various conditions causing glass mildewing can be effectively inhibited when glass is to be processed, alkali liquor on the glass surface can be effectively neutralized, and the occurrence of mildewing is prevented. At the same time, the glass anti-mildew liquid is weakly acidic, which reduces the pollution of acid wastewater to the environment. The selected chemicals are easy to clean and separate, and can be recycled by certain methods, so that the glass surface can be thoroughly cleaned, thereby eliminating the influence of the components of the glass anti-mildew liquid on the subsequent deep processing of the glass.
Description
technical field [0001] The invention belongs to the technical field of glass surface treatment, and in particular relates to a novel anti-mildew liquid for glass. Background technique [0002] Mildew of flat glass is a common problem encountered by many glass manufacturing companies, and it is a common problem when the glass is just produced. Glass mildew refers to the phenomenon that the glass is in the air environment, the surface is in contact with moisture and other substances in the atmosphere and is eroded, resulting in rainbow marks, white spots or fog. During production, after the glass is annealed and needs to be processed in the next step, the glass needs to be placed for a period of time to be processed. During this period of time, the surface temperature of the glass is still higher than room temperature and the air environment humidity is high. It is easy to absorb water molecules to form an alkaline environment and cause glass to become moldy. Usually, it is n...
