Frosted/acid etched glass
Frosted glass is also called frosted glass, dark glass, is to use ordinary flat glass by mechanical sandblasting, manual grinding (such as emery grinding) or chemical method processing (such as hydrofluoric acid corrosion), such as surface processing into rough and uneven translucent glass.Generally multi-purpose above the doors and Windows of the office and bathroom, the glass of other rooms can also be used.
Advantages
(1) Good sound insulation effect: When manufacturing sound insulation glass, it can be made of frosted glass, because frosted glass has a good effect on sound insulation. If frosted glass is used to make sound insulation glass, the sound insulation glass produced is very effective In the production of sound insulation glass, frosted glass is often used to produce sound insulation glass, but as more glass is produced, frosted glass is replaced by other products.
(2) High degree of safety: Frosted glass is a kind of safety glass, which is very safe to use and guarantees personal safety. Glass is a fragile product. After being subjected to external force, the glass is easily broken. It is not safe to use. Moreover, if the glass is damaged, it will increase the user's cost. However, if the frosted glass is used, it is not only a good solution. Safety issues, and the price is relatively low, and the use time is relatively long.
(3) Privacy is protected: From the surface, the frosted glass can't see the situation in the room clearly, giving people a very vague feeling and ensuring the privacy of the room. Although it looks very fuzzy from the surface, it is very clear when viewed from the inside out, and it will not affect the lighting. The indoor lighting is also very good.
Disadvantages
(1) Frosted glass can no longer be cut and reprocessed. The glass can only be processed to the required shape during processing, and then tempered.
(2) Although the strength of frosted glass is stronger than that of ordinary glass, frosted glass has the possibility of spontaneous explosion when the temperature difference changes greatly, while ordinary glass does not have the possibility of spontaneous explosion.
(3) There will be unevenness on the surface of the frosted glass, and there will be a slight thinning of the thickness. Therefore, frosted glass cannot be used as a mirror. When frosted glass is covered with a transparent tape, its surface becomes flat again and the light can be fully reflected, so that a complete image appears on the retina and the eye can see objects again. In addition, you can see the frosted glass clearly by rubbing it with a damp cloth.
Product Application
(1) It is often used for doors, windows and partitions in bathrooms and offices that need to be concealed. The hair should face indoors when using, but the hair should face outwards when using the bathroom.
(2) Common terms In chemical reagent bottles, for example, the mouth of the gas cylinder is frosted, and the frosted glass sheet is used to ensure that the frosted glass is in closer contact with the gas cylinder. Therefore, the frosted side should also be used when using frosted glass, so that the collected gas will not easily leak.
Production technology
The process of producing frosted glass by chemical method is as follows:
(1) Washing and drying: Firstly, the flat glass to be produced frosted glass is washed with water to remove dust and stains, and then dried;
(2) Hoisting: Put the cleaned and dried flat glass into the hoisting rack, the part of the hoisting rack in contact with the glass is cushioned with a tooth-shaped rubber bracket, and the glass is discharged vertically, with a certain distance between the glass and the glass. Hoist with a crane;
(3) Corrosion: Use a crane to immerse the plate glass together with the hoisting frame into the corrosion box, and use a conventional corrosive solution to immerse the glass. The corrosion time is 5-10 minutes. After being lifted by a crane, the residual liquid is drained;
(4) Softening: After drenching the remaining liquid, there is a layer of residue on the frosted glass, which is placed in a softening box to soften it, and the glass is immersed in a conventional softening liquid, and the softening time is 1-2 minutes to remove the residue;
(5) Cleaning: Due to corrosion and softening, the frosted glass body contains many chemical substances, so it must be cleaned. Put the frosted glass on the slide of the washing machine. The slide drives the frosted glass into the washing machine. The washing machine sprays water into the washing machine. Rotate the brush, when the frosted glass is taken out of the washing machine by the slide of the washing machine, the washing of the frosted glass ends;
(6) Put the cleaned frosted glass into the drying room to dry, and it will become single-sided or double-sided frosted glass
