What is the difference between frosted glass and engraved glass?
There are many kinds of glass with wide uses. In addition to the commonly used quartz glass and tempered glass, there are also various types of optical glass, color changing glass, laminated glass and so on. Because there are many kinds of glass, it is more important to choose the right type. In order to find suitable glass products, we need to understand all kinds of glass and be familiar with the characteristics of frosted glass and engraved glass.
1、 Difference between frosted glass and engraved glass
Frosted glass, also known as ground glass and dark glass, is made by treating the surface of ordinary flat glass into a uniform surface by mechanical sand blasting, manual grinding or hydrofluoric acid corrosion. Due to the rough surface, the light has diffuse reflection, light transmission but no penetration. It can make the indoor light soft and not dazzling. It is often used in bathrooms, bathrooms The doors, windows and partitions of the office shall face out of the window
Engraved Glass: the glass engraved with words, patterns and patterns is used as decoration, which is beautiful and generous. The method to achieve this goal is to use the decoration method, that is, the method of etching glass by using chemical agent etchant. As an etchant, hydrofluoric acid has been used for a long time. As an etching method, the glass to be etched is washed, dried and placed flat, The paraffin solution dissolved in gasoline is coated on it as a protective layer, and the required characters or patterns are engraved on the cured paraffin layer. During engraving, the paraffin layer must be engraved to expose the glass. Then, drop hydrofluoric acid on the characters or patterns exposed to the glass. Control the corrosion time according to the depth of the required patterns. After a certain time, wash the paraffin and hydrofluoric acid with warm water, Although this method has been used for a long time, the pollution is serious due to the volatilization of gasoline and hydrofluoric acid; It needs a protective layer and the operation is complex
2、 What is the patterned glass
Painted glass is first pasted with a glass protective film on the glass, and then the pictures to be painted are drawn on the glass film. After they are engraved with a carving knife according to the lines, they can be painted. Generally, the deep color is first applied and then the light color is applied with a spray gun and glass painted paint
2. Frosted glass. It is also made of ordinary flat glass. Generally, the thickness is less than 9 cm, and more than 5 or 6 cm
3. Sandblasted glass. Its performance is basically similar to that of frosted glass. Different frosted glass is changed to sandblasting. Because they are visually similar, many owners and even experienced decoration personnel confuse them
4. Embossed glass is a kind of flat glass made by calendering method. Its main feature is transparent and opaque. It is mostly used in toilet and other decoration areas

Glass
Glass is an amorphous inorganic nonmetallic material, which is 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 materials, and a small amount of auxiliary raw materials. Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O · Cao · 6sio2. The main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings to isolate wind and light, and belongs to mixture. There are also colored glass mixed with oxides or salts of some metals to show color, and tempered glass prepared by physical or chemical methods. Some transparent plastics (such as polymethylmethacrylate) are sometimes called agricultural production system glass.
plate glass
Flat glass is also called white glass or clean glass. Its chemical composition generally belongs to sodium calcium silicate glass, and the composition range is: sio270 ~ 73% (weight, the same below); Al2O30～3%； CaO6～12%； MgO0～4%； Na2O+K2O12～16%。 It has the properties of light transmission, transparency, heat preservation, sound insulation, wear resistance and climate change resistance. Main physical performance indexes of flat glass: refractive index is about 1.52; More than 85% light transmittance (2mm thick glass, except colored and coated glass); Softening temperature 650 ~ 700 ° C; Thermal conductivity 0.81 ~ 0.93 w / (m · Kai); Expansion coefficient 9 ~ 10 × 10-6 / on; The specific gravity is about 2.5; The bending strength is 16 ~ 60 MPa.
Frosted glass
Frosted glass, also known as ground glass and dark glass. It is made by treating the surface of ordinary flat glass into a uniform surface by mechanical sand blasting, manual grinding or hydrofluoric acid corrosion. It is often used for doors, windows and partitions of bathrooms, bathrooms and offices that need to be concealed.
