Glass is a necessity in our daily life. Because of its special properties, it can withstand high temperature and low temperature and maintain good characteristics, so that it can be widely used.


Blown goods are made by air pressure, so there is a great entanglement with the size of air pressure. If the air pressure is too high, the bottom is thin, the mouth is thick, and the air pressure is too small, then the mouth is too thin or the roots cannot be blown, but the mouth is missing. The usual blown goods are bottles and cans. Depression is through in-process mold pressing into the outer mold, and the glass frit is kneaded and shaped. The leisure between the two molds affects the thickness of the goods, while the internal mold is controlled by the process air pressure. Therefore, if the air pressure is too high, the space above and below the two molds will be screened to make the bottom of the goods thinner; if the air pressure is too low, the opposite is true. As usual, straight cups are restricted, but if the goods are relatively high and the side requirements are thin, they are usually blown, and the thinnest of this kind of goods is in the middle, so the middle is easy to break. Centrifugal torsion, with the mold settled on the motor, through the process of a certain speed of the mold to throw off the material for molding. The electric speed is too small to be thrown away, which makes the goods incomplete and the speed is too high. The materials are thrown out or all of them are thrown to the upper part, so that the upper end is thick and the bottom is thin. This method is accepted by the usual strong objects. It is necessary to clamp the goods out with pliers after they are taken out of the mold. If the pliers are rusted, the goods will be stained with rust and the roots cannot be cut off. Therefore, it is necessary to ensure that the pliers are cleaned without rust, and try them with glass water as usual, or receive pliers with rust-free raw materials. At this moment, the same usual goods can be held in the latter process-edge burning, but some goods cannot be molded by one mold, and they need to be welded again. The welding must be held when the goods are just out of the mold, and the other part to be welded must be the melted material that has just been selected. How talented it is to weld well, otherwise it will be easy to connect or crack the goods.


Glass firing technology is closely related to the glass industry. A good technology can make good quality, but it is also very important to choose a reasonable glass furnace design.
