Glass bottles are widely used. They not only have a transparent and beautiful appearance, but also have high practicability. And waste glass bottles can be recycled, so they are the most environmentally friendly packaging goods.
The main raw materials for manufacturing glass bottles include: broken glass, quartz sand, limestone, soda ash and other natural raw materials.
Quartz sand usually accounts for 45% of the formula. Mixing soda ash can make quartz sand melt evenly, while limestone accounts for about 10%, Its function is to make the finished glass more durable.
Put all the raw materials in a special glass furnace and calcine them at 1500 ℃ for one day to form a viscous liquid like honey. These high-temperature solutions come out of the furnace, and the machine will divide them into round strips. Each round strip is used as the quantity of a bottle. They are transported into the material trough in the production workshop of valiant company, where the blank of the bottle can be formed in only a few seconds. Then it will be sent to the blowing mold designed and manufactured by valiant company. The machine will blow compressed air into the blank tire to form the final bottle body. Then a series of heat treatment will be carried out, and the glass will not break in the next cooling due to the drastic change of temperature by heating with a suitable flame. Then annealing process is introduced, annealing furnace will control the cooling speed of the bottle, and release the internal stress gradually. The spray equipment will spray lubricant from the annealing furnace, so that they can pass the inspection and packaging procedures behind the back and enter the automatic inspection process. Valiant attaches great importance to quality inspection, from photographic equipment and detector. Check whether each bottle has defects such as cracks and bubbles, and then confirm the size to ensure that the size and thread of the bottle mouth are within the specified range.
Such a qualified glass bottle was produced. According to industry statistics, not recycling a wine bottle can light a 100 watt bulb for about 4 hours or let a computer run for 30 minutes, so recycling glass is a very meaningful thing. Valiant has always attached great importance to environmental protection and recycles a large number of old glass bottles every year.
