The invention relates to the technical field of
electron tube glass bulbs, and particularly discloses a preparation method and a structure of a novel
electron tube glass
bulb, and the preparation method comprises the following steps: S1,
material selection and pretreatment; s2, forming and
processing; s3, carrying out vacuum treatment and packaging; s4, special process treatment; s5, quality detection and testing; the selected materials have good vacuum holding capacity and thermal
stress resistance so as to adapt to the change of the
working environment of the
electron tube, glass raw materials are strictly screened and cleaned, impurities and pollutants are removed, and the glass raw materials are pretreated by adopting a high-temperature baking process; by selecting the
glass material with
high heat resistance and low expansion coefficient and strict pretreatment and
forming processes, the durability of the electronic tube glass
bulb is remarkably improved, breakage or damage caused by thermal stress due to temperature change is reduced, interference and
noise among electronic elements are reduced by the internal environment of the high-vacuum-degree glass
bulb, and the service life of the electronic tube glass bulb is prolonged. Therefore, the
transmission quality and the tone
quality performance of the
audio signal are improved.
