查询词典 cinder pit

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先，钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能，并且有明显的协同作用，从而能抑制部分点蚀核的产生；其次，钼酸盐复配缓蚀剂的使用，从电化学的角度分析，具有明显的钝化性能，且钝化区间较宽、维钝电流密度较小，从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化，得到有效的修复；最后，对于还有部分蚀孔发展成为闭塞腐蚀电池的情况，钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐，从而有效地减缓了点蚀的恶化，抑制了腐蚀的发展。

This subject is on the basis of a detail investigation of present utilization and recovery of pyrite cinder, and taking pyrite cinder from the Jinshandian vitriol factory of Wuhan Steel and Mining Industry Corporation as raw material.

Most importantly, with analyzing the calcined cinder by X-ray powder diffraction and scanning electron microscope, it was clear that at an appropriate calcination temperature, the activated SiO2 and Al2O3 in alkaline coal-cinder would react with the decomposed fused Na2CO3 to form a new neutral matter nepheline（NaAlSiO4）and other amorphous silicate compounds,causing an obvious reduction of the alkali content in coal-cinder.

采用X射线粉晶衍射及扫描电镜对煅烧后的灰渣进行表征，揭示了含碱灰渣煅烧脱碱过程的实质，即在适宜煅烧温度下，含碱灰渣中被活化的主要矿物质SiO2、Al2O3和熔融并分解的Na2CO3（分解为修饰网络氧化物Na2O）等发生化学反应转变为中性物质霞石（NaAlSiO4）及其他无定形复合硅酸盐，从而降低了灰渣中的碱含量。

In order to improve interlayer pit mud fermentation, self-made pit mud fermenter was used and pit mud functional bacteria were supplied in each turn of fermentation. Such measures could evidently increase contact area between fermented grains and pit mud, enhance ethyl caproate content in fermented grains (enhanced by almost three times than before) with no adverse influence on liquor yield, and improve liquor quality. Its application could effectively settle the problems such as pit mud odor in liquor, difficult operation, recycle use and unsatisfactory effects etc.

采用自制夹泥发酵器和每轮补充窖泥功能菌的夹泥发酵法进行浓香型白酒生产，结果表明，该方法能明显增大糟醅接触窖泥的面积；提高糟醅中己酸乙酯等香味物质的含量，己酸乙酯的含量比对照糟醅增加了近3倍；不影响曲酒的出酒率；可明显提高曲酒的质量；有效地解决了窖泥易进入糟醅，使酒中出现明显的窖泥味、操作困难、难以循环使用、效果不明显等问题。

The functional pit mud was used in liquor production. Four months production practice indicated that the average yield per pit increased by 75.48 kg than before for consecutive three months and quality product rate increased by 8.56 % than before. Besides, the application of funtional pit mud could improve pit mud flavor, strengthen ester aroma of pit mud, reduce the off-flavor of produced liquor, increase main flavoring compositions and the complex flavoring compositions in liquor, perfect liquor body, and enhance the purity and softness of the liquor.

将功能性人工窖泥应用生产，结果表明，投产4个月后，连续3个月每窖平均产量比用原窖泥配方多产酒75.48kg，优质品率比原窖泥配方提高8.56%；功能性窖泥还可改善窖泥风味，增强窖泥的酯香味，减少新窖产酒的邪杂味和泥臭味，增加新酒中的主体香及其复杂香味成分，改善了酒体风格，增强新产酒的绵柔度和纯净感。
