枯矾煅制工艺改进

The Technology Improvement for Forging Alumina

目的 :煅制质优、纯白无杂质的枯矾 ,适应临床需要。方法 :以低压恒温干燥法煅制的枯矾与传统火煅及常压恒温干燥法煅制的枯矾质量进行比较。结果 :低压恒温干燥法煅制的枯矾质纯无杂质、均匀疏松、洁白如雪 ,其生产效率、产品质量、失水率均有显著提高。结论 :低压恒温干燥法煅制枯矾 ,压力在 41～ 5 0 k Pa之间 ,同时温度控制在 130～

Objective: To forge top quality, lily white, spotless alumina for the sake of clinical requirement. Methods: Compare the forged alumina by low pressure, constant temperature dryness with by accustomed pressure dryness and traditional smithing dryness. Results: Forged alumina by low pressure, constant temperature dryness was spotless, uniformity, loosen, pure white like snow. There was a notable progress in creative efficiency, product's quality, lost water's percent compared with the other methods. Conclusion: The forging agreeable condition with low pressure, constant temperature dryness is that pressure keeps between 41 kPa and 50 kPa, temperature maintains between 130℃ and 180℃.
