| 摘 要： | 针对气密性较差的钢筋砼立筒仓 ,选择了AlP自然潮解环流熏蒸和PH3与CO2 混合环流熏蒸两种技术 .从PH3浓度变化、CT积和试虫死亡情况对比分析 ,对经气密性测试 (从 5 0 0Pa降至 2 5 0Pa)半衰期不足 2 5s的钢筋砼立筒仓 ,AlP自然潮解环流熏蒸效果优于PH3与CO2 混合环流熏蒸 .

| Abstract: | Natural AlP deliquescence and PH 3 mixed with CO 2 circulation fumigations were chosen directly against the poor airtight in reinforced concrete silos.PH 3 concentration differentials,Ct product and the mortality of the tested insects were analyzed and compared.The results showed that the effect of Natural AlP deliquescence is better than that of mixture of PH 3 and CO 2 in reinforced concrete silos,in which half life of airtight is less than 25 s (from 500 Pa to 250 Pa). |
