Synthesis and characteristics of glass bottles

The glass bottle is made of more than ten kinds of raw materials, such as broken glass, soda ash, sodium nitrate, shellfish carbonate, quartz sand, etc. It is a kind of container made by 1600 degrees high temperature melting and shaping. It can be produced in different shapes according to different molds. The glass bottles, mainly including a variety of wine bottles, beverage bottles, pickle bottles, honey bottles, canned bottles, coffee bottles, olive oil bottles, tea cups, cosmetic bottles, wine jars, candle cups and other various capacity glass bottles, craft bottles . The glass bottle is sealed and light-transmissive, and can store products that are highly sensitive to humidity for a long time.

Physical and chemical indicators:
Resistance to sudden changes in heat: resistance to rapid cooling, with a temperature difference of 36 degrees Celsius, without bursting.
Dilute acid erosion: acidic solution should be red
Internal stress: the real internal stress is not more than level 4
High temperature resistance: no burst at high temperature of 120 degrees Celsius
Appearance quality standard: white and transparent, the flatness of the bottle mouth is less than 0.6mm, and the plane parallelism between the mouth and the bottom is less than 1mm, no bubbles, opaque sand, cracks, burrs, recessive and dominant blasting!

test:
1: Take 10 qualified finished products into the pressure cooker, heat to 120 degrees Celsius, none of them burst
2: Take a few qualified finished products, heat to a certain temperature, and cool down rapidly under the specified temperature difference, none of them burst
3: Take a few qualified finished products Hand feeling: no scratching feel, no burr on the inner edge, smooth thread Visual inspection: smooth surface, crystal clear and bright, no hidden and dominant blasting!
