1. Customized production process for glass products Steps: batching, melting, forming, annealing and other processes. Introduced as follows: 1. Ingredients, according to the designed bill of materials, weigh the various raw materials and mix them evenly in a blender. The main raw materials of glass are: quartz sand, limestone, feldspar,soda ash, boric acid and the like. 2. Melt and heat the prepared raw materials to form a uniform bubble-free glass. This is a very complicated physical and chemical reaction process. The melting of the glass takes place in the furnace. There are two main types of melting furnaces: one is a kiln, and the glass is contained in the crucible and heated outside the crucible. 3. Forming is the conversion of a molten glass into a solid product having a fixed shape. Forming must be carried out within a certain temperature range. This is a cooling process in which the glass first changes from a viscous liquid state to a plastic state and then to a brittle solid state. The forming method can be divided into two major categories: artificial forming and mechanical forming. A. Artificial forming (1) Blowing, blowing a tube with a nickel-chromium alloy, picking a glass of glass and blowing it while rotating in the mold. Mainly used to form glass bubbles, bottles, balls, etc. (2) Pulling, after blowing into small bubbles, another worker sticks with the top plate, and the two are mainly used to make glass tubes or rods while blowing.

2. (3) Pressing, picking a glass of glass, cutting it with a scissors to drop it into the die, and then pressing it with a punch. Mainly used to form cups, plates, etc. (4) Freeform forming, after picking up materials, directly make crafts with tools such as pliers, scissors, and tweezers. B. Mechanical forming. Since the artificial forming is labor intensive, high in temperature, and poor in condition, most of it has been replaced by mechanical forming except for free forming. In addition to pressing, blowing, and drawing, mechanical forming has - (1) Calendering method for producing thick flat glass, engraved glass, clipped wire glass, and the like. (2) Casting method to produce optical glass. (3) Centrifugal casting method for manufacturing large diameter glass tubes, vessels and large-capacity reaction pots. This is to inject the glass melt into a mold that rotates at high speed, and the glass is pressed against the wall of the mold due to centrifugal force, and the rotation continues until the glass is hardened. (4) Sintering method for producing foam glass. It is a kind of good heat insulation and sound insulation material by adding a foaming agent to the glass powder and heating it in a covered metal mold. The glass forms many closed bubbles during the heating process. 4. Annealing. The glass undergoes intense temperature changes and shape changes during the forming process, which leaves thermal stress in the glass. This thermal stress reduces the strength and thermal stability of the glass article. If it is directly cooled, it is likely to rupture itself during storage, transportation, and use during cooling or later. Note: In order to eliminate the cold explosion phenomenon, the glass article must be annealed after forming. Annealing is to heat or slowly cool for a period of time to eliminate or reduce the thermal stress in the glass to an allowable value. Glass is an amorphous inorganic non-metallic material, generally made up 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 materials are added. of. Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is a silicate double salt, which is an amorphous solid with a random structure.
