After stored for 30 d, MAP+1-MCP tablet, MAP+It’s Fresh ethylene adsorbent paper, MAP+200 μL/L fludioxonil and MAP+0.3% natamycin did not significantly reduce the decay rate of sweet cheery. After stored for 60 d, MAP+It’s Fresh ethylene adsorbent paper, fludioxonil and natamycin significantly reduced the decay rate of sweet cherry.[Conclusion] The use of preservatives in late storage inhibits the decay of sweet cherry.展开更多
以柯尔碱膨润土为研究对象,利用XRD、FTIR和SEM等分析手段对其成分、结构和物化性质等进行了系统分析。在此基础上,采用自然沉降法和高速离心法对其进行提纯,通过测定提纯土的吸蓝量和膨胀容等性能指标及X-射线衍射分析对提纯效果进行...以柯尔碱膨润土为研究对象,利用XRD、FTIR和SEM等分析手段对其成分、结构和物化性质等进行了系统分析。在此基础上,采用自然沉降法和高速离心法对其进行提纯,通过测定提纯土的吸蓝量和膨胀容等性能指标及X-射线衍射分析对提纯效果进行评价。结果表明,柯尔碱膨润土蒙脱石含量约为57%、吸蓝量为0.3039 g/g、膨胀容为10.75 m L/g,属于中低品位钠基膨润土矿,所含蒙脱石晶格完全破坏的温度在800℃以上,热稳定性较好。采用2种不同提纯方法都可以达到很明显的提纯效果,但综合比较高速离心法效果更明显,可获得吸蓝量为0.4958 g/g的膨润土精矿,并且该提纯方法具有周期短、效率高的优点。展开更多
