First, a simple discussion for the mechanism about electrostatic atomization of the liquids has been given ; then the paper theoretically analyzed waving course, liquid drop producing course, and the liquid drop diffusing course in electrostatics atomization process., gave an analysis about the methods about carrying charges to the liquid drop, and analyzed that liquid with high electrical conductivity can be carried charges and atomized by electric field, while the isolated liquid with low electrical conductivity can be charged fully with the soakage electrode and inducing charge methods. at last the paper designed and configured the experimental equipment, conducted the atomization experiment to the three liquid medium - kerosene, emulsifier and alcohol under the same environment, handled the experimental results, then summarized the relationship between liquid electrostatic atomization effect and liquid surface tension, electronic conductivity and viscosity, along with the influence of voltage to electrostatic atomization and so on, found out the liquid atomization rule in high voltage electrostatic field
首先,對液體介質的靜電霧化機理作了初步的探討,理論上分析了液體霧化過程中射流區、波紋區、霧滴區和霧滴擴散區;然後對液體荷電方法進行了研究分析,對于高電導率的液體,場致荷電和接觸荷電可以使其霧化,而對于電導率較低的絕緣液體,需用浸潤電極荷電和感應荷電方法使其充分帶電;最後,根據前面的研究分析,設計和組裝試驗裝置,在同一環境下對煤油、乳化劑、酒精三種不同液體介質進行高壓靜電霧化試驗,並對試驗結果進行分析處理,總結出液體靜電霧化與液體表面張力、電導率和粘度的關系及電壓對液體靜電霧化的影響等,得出高壓靜電場中液體霧化的一般規律。The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete
研究結果表明,水泥的品種和用量是影響混凝土收縮值的主要因素之一,當混凝土中水泥用量超過470kg / m ~ 3時,混凝土的收縮值超過400 10 ~ ( - 6 ) ,在約束狀態下存在高開裂風險;採用細砂使混凝土單位用水量顯著提高,收縮值也大幅增加;優質粉煤灰總體上能抑制混凝土的收縮,以超量方式摻入其抑制作用更加明顯,但粉煤灰混凝土早期的粘聚性較差,應注意養護,以免失水產生龜裂;早強減水劑和緩凝減水劑都會使混凝土收縮值增加;膨脹劑只能補償混凝土部分收縮,同時受緩凝劑和粉煤灰的抑制,而且膨脹使混凝土的體積安定性增加了不確定因素,膨脹劑不是解決混凝土收縮裂縫的良方。Abstract : basic stuff of sinter flyash ceramisite is flyash and clay as agglomerant. the si nter flyash ceramisite is of dense in structure, low porosity which can improve t he mechanical properties of the material. it has properties such as high strong a nd low absorption of water and better stability. it is a new type ofbuliding mate rial
