- 摘要:
- 为探究氧烛成分中的催化剂对其产氧速率与稳定性是否具有影响，以Co2O3为研究对象，在其质量分数分别为0%，2%，3%，4%，5%下，将其与NaClO3进行二元TG-DTG联合热重分析，通过对比各混合物的热解始末温度及其他特征温度，探究了Co2O3对NaClO3热解的催化效果、速率及稳定性的影响。研究结果表明：Co2O3对NaClO3热解的催化效果随其质量分数增加而增强，并在4%时达到最佳；少量Co2O3（0%~2%）可使得NaClO3热解过程出现多阶梯，热解变得不稳定,但适量Co2O3（3%~5%）却可在不影响NaClO3热解稳定性的情况下，使其热解温度区间变宽，热解速率变慢。
- Abstract:
- In order to investigate whether the catalyst in the composition of oxygen candle has the effect on its oxygen production rate and stability, taking Co2O3 as the research object, the binary TG-DTG combined thermogravimetric analysis was carried out together with NaClO3 under the mass fraction of Co2O3 as 0%, 2%, 3%, 4% and 5%, respectively. The influence of Co2O3 on the catalytic effect, rate and stability of NaClO3 pyrolysis was investigated by comparing the pyrolysis initiation and end temperatures and other characteristic temperatures of each mixture. The results showed that the catalytic effect of Co2O3 for NaClO3 pyrolysis increased with the increase of its mass fraction, and the optimum catalytic effect was achieved at 4%. A small amount of Co2O3 (0%-2%) could make the multiple steps appear in the NaClO3 pyrolysis process, with an unstable pyrolysis, but a proper amount of Co2O3 (3%-5%) could make the pyrolysis temperature range become wider and the pyrolysis rate slow down without affecting the pyrolysis stability of NaClO3.
