Glass has good see-through, light transmission properties, high chemical stability, and can obtain strong mechanical strength and thermal insulation effect according to different processing methods, and can even make the glass autonomously change color and isolate excessive light, so it is commonly used To meet different needs in all walks of life. Next, please look at the glass frosting process and the production method of the glass frosting effect to enhance your understanding.

1.What are the advantages of glass sandblasting

Among various surface pretreatment methods, sandblasting (shot blasting) has a more thorough effect, stronger adaptability, and a wider range of applications. This is because: the surface is cleaned faster and more thoroughly; only sandblasting can be used. There are 4 cleaning levels acceptable to everyone; sandblasting can clean surfaces that are usually difficult to clean, and some special tools can be used to clean the inner surface of the pipeline, and the cost of sandblasting is lower.

Sandblasting can make the cleaned surface obtain the required cleanliness and the surface roughness at the same time, and improve the adhesion of the coating on the basic surface. No matter how good the paint is, it cannot stick to the surface of the workpiece without surface treatment for a long time. The function of surface pretreatment is to clean the surface and generate the required roughness to "lock in" the coating on the surface. After the surface of the sandblasted workpiece is coated with a good industrial coating, the coating life can be more than 3.5 times longer than the same quality coating on the surface after other methods. Another advantage of sandblasting (shot blasting) is that the surface roughness can be determined in advance according to the requirements and can be easily achieved during the cleaning process.

2. How to make the frosting effect of glass

Frosted glass is also called frosted glass and dark glass. It is made of ordinary flat glass by mechanical sandblasting, manual grinding or hydrofluoric acid corrosion and other methods to treat the surface into a uniform surface.

1. Hand-grinding, frosted glass is the past practice, it is to use sand, pour water and put some fine sand back and forth.

2. Sandblasting, sandblasting is performed after the glass glass is cut and edging/before installation. In the dedicated sandblasting room, use a sandblasting gun to spray emery at high pressure (it should be called emery), and the glass surface is rough. Surface, physical method.

3. Frosting, with hydrofluoric acid solution (HF), you can double-sided frosting and single-sided frosting (the non-frosted side should be covered with a protective film), and the frosting powder is diluted with water in a special bucket/pool. After a certain concentration, put the glass into the glass. At the same time, make sure that the hydrofluoric acid in the solution is consistent. You can use compressed air to agitate the solution. After a certain period of time, take out the glass and clean it.

Sandblasting

The process of using the impact of high-speed sand flow to clean and roughen the surface of the substrate. Compressed air is used as the power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, emery sand, iron sand, Hainan sand) at high speed to the surface of the workpiece to be treated, so that the appearance or shape of the outer surface of the workpiece surface is changed , Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved. Therefore, the fatigue resistance of the workpiece is improved, and its and coating The adhesion between the layers extends the durability of the coating film, and is also conducive to the leveling and decoration of the coating.

Glass

Glass is an amorphous inorganic non-metallic material, generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added. of. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings to separate wind and transmit light. It is a mixture. There are also colored glass mixed with oxides or salts of certain metals to show color, and tempered glass made by physical or chemical methods.
