High-pressure gas discharge lamp ceramic tube and preparation method thereof
The invention provides a high-pressure gas discharge lamp ceramic tube, two end areas of the ceramic tube are coated with thermal insulation layers, and the thermal insulation layers are a mixture of 10%-30% by mass of alumina and 70%-90% by mass of zirconia. The preparation method of the ceramic tube of the high-pressure gas discharge lamp comprises the following steps: pressing and molding raw materials of the required ceramic tube according to the size required by the technology, and then biscuiting and sintering the raw materials in a high-temperature furnace at 1100-1300 DEG C; and after the ceramic tube is cooled, coating two end areas of the ceramic tube with a prepared mixture of 10%-30% of aluminum oxide and 70%-90% of zirconium oxide by using powder spraying equipment. And putting the coated ceramic tube into a high-temperature furnace, sintering at 1600-1800 DEG C, and cooling to finish the preparation. According to the ceramic tube manufactured through the method, in the long-term use process, the heat preservation layer does not move or fall off, the product consistency is good, and the 20 V lamp voltage can also be increased in a product with the outer tube needing to be inflated.
本发明提供了一种高压气体放电灯陶瓷管，在陶瓷管两端区域涂有保温层，保温层是质量比10%‑30%的氧化铝和70%‑90%的氧化锆的混合物。高压气体放电灯陶瓷管的制备方法，包括以下步骤：将所需的陶瓷管按照技术要求的尺寸，将原料压制成型后在高温炉中进行1100℃‑1300℃的素烧烧结。陶瓷管待冷却后，用喷粉设备将配置好的10%‑30%的氧化铝和70%‑90%的氧化锆的混合物涂覆在陶瓷管两端区域。将涂覆好的陶瓷管放入高温炉中进行1600‑1800℃烧结，等冷却后，完成制备。本发明制作的陶瓷管在长期使用中，保温层无移动和脱落风险，产品一致性较好，且在外管需要充气的产品中同样可以提高20V灯电压。
