Why should hot melt glass go through pickling and soaking in Foshan tempered glass factory

Release time:

Cleaning effect: The basic principle of pickling glass is to remove dirt, grease, dust and other impure substances on the glass surface by soaking the glass surface in a specific acid solution and using the chemical reaction between acid and glass surface substances. This process helps to restore the cleanliness and transparency of the glass.

We are a hot melt glass factory in Guangdong, which can provide you with the latest hot melt glass prices. We also have the latest hot melt glass processing technology and experienced hot melt glass installation methods. Customer feedback on hot melt glass is very good.

The main reasons why glass should be pickled and soaked are as follows:

1. removal of surface dirt and impure substances

Formation and expansion of holes: under the action of acid solution, acid molecules will react with the glass surface to form a layer of tiny holes. As the pickling process continues, these holes will gradually expand, making it easier for dirt and impure materials to be stripped and removed.

2. improve surface properties

Increase roughness: The pickling process not only removes dirt, but also produces tiny bumps and depressions on the glass surface, thereby increasing its surface roughness. This increase in roughness helps to improve the weathering resistance of the glass, making it more weather-resistant and durable.

Formation of silicate layer: The surface of the glass after pickling will form a layer of about 1 micron thick, hard and dense silicate layer. This silicate layer not only enhances the compressive strength of the glass, but also improves its wear resistance and corrosion resistance.

3. improve aesthetics and light transmittance

Improve the appearance and aesthetics: The surface of the glass after pickling is smoother, transparent, free of defects and stains, which greatly improves the appearance and aesthetics of the glass.

Increase light transmittance: Due to the removal of dirt and impure substances, and the formation of silicate layers, the pickled glass has higher light transmittance and brightness. This makes the room more bright and comfortable, improve the living and working environment quality.

Prolong service life

Enhanced durability: pickling treatment effectively enhances the durability of the glass, making it more resistant to the erosion of external environmental factors. This helps to extend the service life of the glass and reduce the frequency of replacement and maintenance.

Prevent defects: pickling can also prevent defects such as potholes and spots on the glass surface, further ensuring the quality and aesthetics of the glass.

5. considerations

Professional operation: Pickling glass needs to be carried out under the guidance of professionals to ensure the safety and effectiveness of the operation. People who do not understand the operation cannot carry out pickling without permission.

Safety protection: during the pickling process, corrosive gas will be produced, which is harmful to health. Therefore, the operator should wear protective equipment, such as protective clothing, gloves, masks, etc., and pay attention to ventilation, to avoid direct inhalation of corrosive gas.

Acidity control: In order to ensure the pickling effect, the acidity used should be appropriate. Too high or too low acidity will adversely affect the quality of the glass. Therefore, acidity should be accurately determined before pickling to ensure compliance with standards.

In summary, the glass can be pickled and soaked to remove surface dirt, improve surface performance, improve aesthetics and light transmittance, extend service life, and need to pay attention to safety protection and acidity control during operation.
