摘要
Abstract
In this paper,using sodium silicate solution as raw material,a series of studies were carried out by using carbonization process.The properties of SiO2 products produced by this process are much higher than those of other production processes.By changing the concentration of sodium silicate solution,reaction temperature,additive dosage,CO2 introduction rate and other influencing factors,the effect of ion concentration on the morphology of silica was investigated.The results show that the concentration of sodium silicate solution has an obvious effect on the properties of silica.With the increase of sodium silicate concentration,DBP increases from 1.28 mL/g to 3.09 mL/g.With the increase of reaction temperature and the addition of PEG6000,DBP increases gradually and then decreases,and the final reaction temperature is 80℃and the addition of PEG6000 is 6g.With the increase of CO2 penetration speed,the product performance can be improved and the reaction time can be shortened at the same time.Considering that the penetration speed is 1.2L/min.关键词
