【摘要】 目的研究长效缓释ClO2反应盒制作技术和方法及反应盒的应用价值。方法将特制的A、B 2种物料组装在一个圆形塑料盒中,制成长效缓释ClO2反应盒。检测反应盒连续释放ClO2的长效性和释放率(mg.h-1);用反应盒缓释出来的ClO2气体和其水溶液分别作杀菌试验;用反应盒缓释的ClO2气体作食品保鲜防腐和除臭试验等。结果反应盒在1~6个月内,ClO2释放率维持在20 mg.h-1左右,超过6个月,随月份数增加,ClO2释放率逐渐下降。气体ClO2杀灭大肠肝菌:0.5 mg.h-1作用12.0 h杀灭率99.97%;1.0 mg.h-1作用12.0 h杀灭率100%;3.0 mg.h-1作用3.0 h杀灭率100%;5.0 mg.h-1作用1.5 h杀灭率100%。ClO2水溶液杀灭大肠杆菌:2.5 mg.h-1作用5 min的杀灭率为99.99%;5.0 mg.h-1作用5 min杀灭率为100%;杀灭枯草杆菌黑色变种芽胞:100 mg.h-1作用10 min杀灭率100%;200 mg.h-1作用5 min杀灭率100%。结论长效缓释ClO2反应盒用于消毒杀菌、食品保鲜、除臭等效果明显,有一定实用价值。更多还原

【Abstract】 Objective To develop the production technique of a long acting and slow releasing ClO₂ generating box and the applicable value of the box. Methods The ClO₂ generating box was a round plastic box containing 2 special materials（A&B）.The long acting character and slow releasing rate(mg·h^-1) were tested;the experiments on bacteriocidal effect,keeping food fresh,deodorizing by CIO₂ released were carried out. Results The releasing rate of the ClO₂ generating box kept about 20 mg·h^-1 in the first 6 months,and then gradually descended along with time increasing.The bacteriocidal rates of gaseous ClO₂ for coliform:were 99.97% with 0.5 mg·L^-1 ClO₂ for 12.0 h,100% with 1.0 mg·L^-1 ClO₂ for 12.0 h,100% with 3.0 mg·L^-1 ClO₂ for 3.0 h,100% with 5.0 mg·L^-1 ClO₂ for 1.5 h.The bacteriocidal rateas of ClO₂ liquor for coliform: were 99.99% with 2.5 mg·L^-1 ClO₂ for 5 min,100% with 5.0 mg·L^-1 ClO₂ for 5 min,and for black spore bacillus subtilus: were 100% with 100 mg·L^-1 ClO₂ for 10 min,100% with 200 mg·L^-1 ClO₂ for 5 min.Conclusion The long acting and slow releasing ClO₂ generating box can keep food fresh without contamination,and can bring good deodorization effect,too.It has certain practical value.更多还原
