化学和聚合工业的发展,使我们有可能广泛选择制造工业用布,其中包括制造过滤用布的材料(尼龙、奥纶、萨冉树脂、紫尼尔、维萦等)。苏联国外的铁矿工业中,通常都用合成纤维来做过滤用布,这些合成纤维的强度很大。例如,美国的一些选矿厂所使用的萨冉树脂单纤维滤布的使用期限达到了1000小时。近年来,苏联的工业也在生产一些合成纤维滤布。 1961年以前,在克里沃罗格各选矿厂中,只用棉织滤布来过滤铁精矿。棉织滤布的过滤性能很好,但其强度较小,只能工作70小时左右。致使克里沃罗格
The chemical and polymerization industries have made it possible for us to choose from a wide range of industrial fabrics, including materials for the manufacture of filter cloths (nylon, oran, saran resin, sirolimus, etc.). In the iron ore industry outside the Soviet Union, synthetic fabrics are usually used for filtration. The strength of these synthetic fibers is very high. For example, Saran resin monofilament filter cloths used in some of the U.S. concentrators have a useful life of 1,000 hours. In recent years, the Soviet Union's industry is also producing some synthetic fiber filter cloth. Prior to 1961, only the cotton filter cloth was used to filter iron concentrates at the Kerry Vorogall concentrator. Cotton filter cloth filter performance is good, but its intensity is small, can only work for about 70 hours. Cause Krivoy Rogge
