The structure stress in glass bottles

2020-11-11
In the process of production, glass bottle subjected to intense and uneven temperature variation, thermal stress is produced.
The thermal stress can reduce the glass strength and thermal stability.
Thermoforming products if without annealing make its natural cooling, is in the process of cooling, storage, use, produces the crack.
annealing is to eliminate or reduce the thermal stress in glass products to the allowable values of the heat treatment process. Thin-walled products ( Such as light bulbs, etc. ) And glass fiber after forming due to thermal stress is small, in addition to properly controlled cooling speed, generally no longer annealing. If the glass surface layer have regular and uniform distribution of compressive stress can improve the glass strength and thermal stability. quenching strengthen is the application of this principle.
glass bottles of stress in general can be divided into three categories: thermal stress and structural stress and mechanical stress.
the thermal stress in eco-friendly tube bottles is due to the temperature difference and the stresses are present in the glass, according to its characteristics can be divided into two categories, temporary stress and permanent stress.
glass structure caused by uneven chemical composition on the uneven stress according to structure stress. It belongs to the permanent stress, glass even after annealing can't eliminate the stress. Uneven in glass composition of body, its thermal expansion coefficient and the main body of glass are not identical, and therefore the main body of glass and uneven contraction and expansion quantity is not the same, the stress on the interface, so the annealing cannot eliminate this kind of stress. For example, when the existing in the glass stones, stripes and knot, will cause stress on the interface of the defects.
