浅圆仓环流熏蒸应用技术及熏蒸效果 总被引:6,自引:3,他引:3
在我国新建的浅圈仓中,采用磷化氢仓外发生器和移动式环流装置进行环流熏蒸应用技术和熏蒸效果的试验研究。本试验仓房的气密性为空仓500Pa压力半衰期73s,磷化铝片剂用药剂量为2g/m^3。投药结束经12h的五流,粮堆各层磷化氢浓度均达到50ml/m^3以上;经24h环流,各层磷化氢浓度均达到100mg/m^3以上,并基于趋于均匀。在投药后15d的密闭期内,粮堆各检测点的磷化氢气体浓度均在100ml/m^3以上。熏蒸结束后检查仓内预埋试虫和仓内害虫的死亡情况,害虫死亡率均达到100%,表明熏蒸杀虫效果好。同时还发现,环注熏蒸对仓内粮温没有明显的影响。 相似文献

The purpose of the study was to investigate the effect of fibre content and method of application of selected interfacing fabrics on appearance of garments after repeated laundering. Experimental fabrics were three interfacings of 100% polyester sew-in, 100% rayon and 100% polyester fusible, and two white fashion fabrics of polyester/cotton durable press treated and 100% cotton. Thirty blouses were constructed and divided into six groups representing six combinations of fashion and interfacing fabrics. Evaluation methods included appearance, dimensional stability and stiffness. Data were statistically analysed using t tests and Pearson rank order correlation coefficient. Results showed that method of applying interfacing fabrics had a significant effect on appearance of the combined fashion and interfacing fabrics. Sew-in method resulted in satisfactory appearance throughout repeated laundering for polyester/cotton DP fabric. Deterioration of adhesive resin of fusible interfacings in the laundering process resulted in significant shrinkage and poor appearance. Also, relationship was found between per cent shrinkage and appearance ratings indicating that as per cent shrinkage increased, appearance ratings decreased. Effect of fibre content of interfacings on appearance was not significant. However, interfacing fabrics were found to be the major contributor to shrinkage of composite fabric and not the fashion fabrics. Poor appearance of fusible interfacings was related also to per cent loss of stiffness. 相似文献

本刊第四期刊发的《有限责任公司股东能否对部分股权行使“有限购买权”?》一文,颇受读者关注,有读者反映读了此文很受启发。近来,我国证券市场十分活跃,作为一种特殊形态的有限责任公司的股权继承,较一般的股权转让更为复杂,部分股民对此的“认知度”往往高,有的甚至模糊不清。本期“经济与法”特刊发施剑蓉《股东资格可以依法继承吗?》一文,希望对读者有所帮助。[编者按] 相似文献

The purpose of this study was to investigate the bleaching efficiency of activated sodium perborate at low washing temperatures and the resulting energy saving. The comparison of the washing efficiency of basic and activated detergent was based on practical washing tests. The types of dirt used were coffee, fruit juice, tea, blood and a soot-oil mixture. The washing temperatures were 50, 60, 70 and 80°C. The cleanness of the washing was determined by a whiteness measurement. The consumption of electrical energy was measured with a kWh-meter. The higher the temperature, the more effectively all the types of dirt were removed from the textiles. With activated detergent a cleanness was obtained at 50°C and 60°C that was almost as good as with basic detergent at 80°C. The coloured types of dirt washed out more easily than blood or the soot and oil mixture. An average saving of 20% in the consumption of energy was obtained when the washing temperature was lowered by 10°C. With activated detergent, 45% of the energy consumed using basic detergent was saved with no reduction in the final cleanness. 相似文献
