FAST MEASUREMENT OF ASH CONTENT IN COAL WASHING PLANT

The coal filter cake is a product of fine coal after floatation which has an ash content of 7-13%, water content of 30±2%, and a particle size of less than 1 mm. The ash content was measured by the intensity of the single backscattered gamma-ray, and its accuracy is mainly dependent on the energy of the gamma-ray. The 238Pu low energy photon source is selected in this work. The energy of its gamma-ray is 15 keV, which can result not only in the best sensitivity, but also in the lowest contribution to the environment radiation. The root mean square deviation of the ash measurement is±0.33% (±1σ).     

Colour extension properties of individual pigments and effects on shades of foundations in cake form

The mechanism of colour change during the pigment dispersion process and during powder application to the skin surface was studied by examining the colour extension properties of Yellow. Red , and Black iron oxides in white powder bases. A new measure for the evaluation of the degree of colour extension was devised. This measure corresponded well with human visual sensation, and was found to be useful for comparing the rates of colour extension of pigments. The rate of colour extension of pigments was found to vary in the order: Yellow acicular Red granular Red Black. This result explains colour darkening and the change towards reddish tones during the pigment dispersion process, because Yellow extends fully in the early stage of the process but Red , especially in granular form, and Black continue to extend even in the later stage. Acicular Red iron oxide is more favourably employed than the granular form to attain sufficient colour extension of foundations with lower energy expenditure, and to decrease the discrepancy between the cake colour and the colour of applied powder.

滤饼过滤中滤饼的洗涤及应用

对置换洗涤过程、机理、洗涤效率、洗涤滤液中溶质质量分数的变化进行了分析;导出洗涤比R为变数时,多级逆流置换洗涤的计算方程;通过对滤饼洗涤试验得出:滤饼中溶质的去除与洗涤液用量有关与其是否含溶质基本无关;同时对柠檬酸生产中的石膏滤饼的洗涤试验表明:置换洗涤效率E在R>1时,E随着R的增加而减小;对石膏滤饼多级逆流置换洗涤结果的试验值与计算值十分接近,该计算方程可用于指导工业生产。
