【摘要】 本研究利用正交试验及单因素试验考察了不同复配条件对纳米SiO₂在ACQ溶液中稳定性的影响。结果表明,对溶液沉降率影响程度依次为:超声时间>Si0₂:六偏磷酸钠>ACQ浓度>SiO₂质量。SiO₂粒子在ACQ防腐剂溶液中的稳定性随着ACQ浓度升高先增强后变弱。对于一定浓度的ACQ溶液而言,SiO₂粒子在溶液中的沉降率随着其质量的增加而基本会呈线性增加趋势。选择合理的SiO₂与六偏磷酸钠的比例,以及溶液的超声时间,有利于提高溶液整体的稳定性。更多还原

【Abstract】 The stability of nano-SiO₂ based amine copper quat（ACQ） solution with different compound conditions was investigated using Orthogonal and single factor tests in this paper.the results show that the degree of influence of various factors on the solution subsidence,in sequence,is:ultrasonication time > SiO₂ / sodium hexametaphosphate ratio > ACQ concentration > SiO₂ amount.The stability of the SiO₂ particles in the ACQ preservative solution first increases and then decreases as the ACQ concentration increases.The sedimentation rate of the SiO₂ particles in ACQ solution exhibits a linear increase when the amount increases.Thus,it is critical to select the reasonable compound conditions of ACQ preservative including the proportion of SiO₂ / sodium hexametaphosphate and ultrasonication time to improve the whole stability of nano-SiO₂ within ACQ.更多还原
