What is the main category of glass machinery? What is the processing principle of glass toughening furnace?

Glass is not only transparent, and the strength and hardness are very high, it’s an indispensable material in ordinary production and life.

There are various types of glass, float glass, tempered glass, hot melt glass, laminated glass, frosted glass and other special functions glass.

If you want to know the category of the glass machinery and the principle of glass toughening furnace processing, the following info will help you.

·       What is the main category of glass machinery?

Glass machinery refers to the glass production and processing in the use of industrial machinery and equipment. Glass machinery is divided into two main categories: glass cold treatment equipment and glass heat treatment equipment. Glass cold treatment equipment including glass cleaning machine, glass edge grinder, glass blasting machine, etc., glass appearance processing; The glass heat treatment equipment includes tempering furnace, hot bending furnace and so on.

Glass machinery includes the following categories: float glass production line, the method of production line, toughened furnace, homogeneous furnace, laminating line, hollow line, coating line, screen printing equipment, glass edge grinding machine, glass washing machine, glass sandblasting machine, polishing machine, slice machine, cutting machine, drilling machine, engraving machine, etc., is one of the more common glass washing machine, glass edge grinding machine.

·       The Processing principle of glass toughening furnace

Glass tempering furnace is an equipment that produces tempered glass by physical or chemical means, including physical tempered glass equipment and chemical tempered glass equipment.

Physical glass toughening equipment through the plate glass heating, and then the rapid cooling technology processing, so that the surface of the cooled glass formed compressive stress, tension stress formed in the glass, so as to improve the strength of glass, so that popular annealed glass into toughened glass equipment. Because this type of toughening does not change the chemical composition of the glass, it is called physical glass toughening equipment.

According to the heating characteristics of the equipment can be divided into forced convection heating tempering equipment and radiation heating tempering equipment; If according to the structure of the equipment, functional characteristics to be divided, it can be divided into combined toughening equipment, flat toughening equipment, bending toughening glass equipment, continuous toughening equipment, two-way toughening equipment, hanging furnace and so on. Chemical toughening equipment is through changing the chemical composition of the glass to improve the strength of the glass, the appearance of deal kali, alkali metal ion exchange and other ways; Because this kind of toughening style changes the chemical composition of glass, it is called chemical type glass toughening equipment.

·       Relevant concepts


Glass, non-crystalline inorganic non-metallic materials, is made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda, etc.) as the primary raw materials, plus a small number of auxiliary materials. Its principal ingredients are silicon dioxide and other oxides.

The chemical composition of glass is Na2SiO3, CaSiO3, SiO2 or Na2O · CaO2 · 6SiO2, etc., the primary component is silicate compound salt, is a kind of amorphous solid without defined structure. It is generally used in buildings to isolate wind and light, and belongs to inclusions. There are also tinted glass mixed with the oxides of certain metals or a little salt to show the color, and toughened glass made by physical or chemical means.
