【摘要】 目的:研究P型纳米二氧化硅载银抗菌粉抗真菌效果及耐热性和稳定性。方法:(1)测定不同浓度,不同作用时间的抗真菌率。(2)耐高温和稳定性测试。结果:P型纳米二氧化硅载银抗菌粉浓度越高抗真菌效果越好,作用时间越长抗真菌效果越好。最小抑菌浓度,P型纳米二氧化硅载银抗菌粉(含银0.35%)1 g+5 mL水与白色念珠菌作用20分钟平均抑菌率可达70.21%。P型纳米二氧化硅载银抗菌粉置于94℃电热恒温水浴锅中放置14天后,配制浓度为1 g+5 mL的药液与白色念珠菌作用20分钟,抗真菌率仍可达到56.25%。结论:P型纳米二氧化硅载银抗菌稳定性很好,耐高温、不失效。更多还原

【Abstract】 Objective: Study the effect of anti-Fungus,high temperature resistance and stability of with Model P’s nanometer added with silver.Methods: First,determine the different density and anti-Fungus rate in different function time.second,test of high temperature resistance and stability.Results: the higher density of the anti-bacteria powder of P-Type nanometer silicon oxidize added with silver,the longer of the functioning time,the better of the anti Fungus result.The minimum of anti-Fungus concentration,the processing of P-type nanometer silicon dioxide added with silver(content of silver0.35%)1 g+5 mL of water with canidia Albicans for 20 minutes,the average rate of anti-Fungus can reach 70.21 %.After having put anti-bacteria powder of P-type nanometer silicon oxidize added with silver in a 94 ℃ constant temperature power heated container for 14 days and making up medical fluid with a concentration of 1 g+5 mL and functioned with canidia Albicans for 20 minutes,its anti-Fungus rate still could be as high as 56.25%.Conclusions: That the stability of P-type silicon oxidize added with silver is good,it can resist high temperature and function well.更多还原
