漂珠用于调湿材料的改性研究

Study on Modification of Fly Ash Cenospheres Used for Humidity Controlling Material

用HF酸对漂珠进行改性处理,研究了改性剂浓度和处理时间对改性漂珠的微观形貌,吸放湿性能的影响,并与硅藻土及火山灰吸放湿性能进行比较发现:改性漂珠的吸放湿性能优于硅藻土与火山灰接近,吸附甲醛性能也有很大改善。

The fly ash cenospheres were modified with HF acid.The effects of modification agent concentration and treatment time on the microstructure and hygroscopic properties of modified fly ash cenospheres were studied.Compared with diatomite and volcanic ash,the moisture absorption and desorption performance of modified fly ash cenospheres is higher than that of diatomite,and is close to that of volcanic ash.Moreover,the formaldehyde adsorption performance of fly ash cenospheres also improved greatly.
