Method for removing stress of thick-bottom glass bottle

The invention provides a method for removing stress of a thick-bottom glass bottle, belonging to the technical field of glass bottle processing. The method comprises the following steps: firstly, carrying out surface treatment on the thick-bottom glass bottle; then successively conducting preheating, uniform heating, heat treatment of the bottom of the bottle, and polishing; and finally, carrying out annealing treatment. By means of the above processing technology, stress in the thick-bottom glass bottle can be effectively removed, and the strength and heat stability of the glass bottle are improved. 本发明提供了一种去除厚底玻璃瓶应力的方法，涉及玻璃瓶加工技术领域。本发明将厚底玻璃瓶先进行表面处理，然后再进行预热、匀热、瓶底热处理、抛光之后，最后进行退火处理。利用本发明的加工工艺可以有效除去厚底玻璃瓶中的应力，提高玻璃瓶的强度以及热稳定性。
