平盘过滤机滤布国产化试验研究及应用

Experimental researches and appliance in indigenous filter cloth of flat check filter

平盘过滤机滤布国产化是氧化铝生产研究的重要课题之一,作者在对法国产滤布进行分析和广泛调研的基础上,根据我国氧化铝物料的特性,研制出了NP310B新型过滤布。工业试验及应用表明:它不仅具有价格低廉,使用寿命长、适应大下料量的特点,而且滤液浮游物、氢氧化铝单位产能、附碱含量和滤饼含水率均明显优于原装法国产滤布,取得了很好的经济效益和社会效益,在本行业具有较广阔的推广和应用前景。

Indigenous filter cloth of flat check filter is one of important researches of a-lumina product.At the basis of analyze and wide investigation to filter cloth made in France.According to property of alumina material,we have made a new filter cloth-NP310B.Technical test have firmed that it is lower in price,longer in using life-span than France's.Whatever,it is useable when the quantity of added material is more,and much better in floating material of filter liquid,the content of accessory alkali and the rate of containing water of filter cake than France's.So it can gain high economy and society benefit,have a good future in extending and ap-pliance.
