多孔烧结材料作为金属过滤器来讲,在工业上的意义越来越大。早在一九三○年就用粉末冶金法制造了青铜过滤器。因为从青铜制取金属过滤器比较简单,并且能耐腐蚀和耐热,所以青铜过滤器得以在许多方面应用。非合金钢或耐腐蚀钢过滤器,由于其耐腐蚀,所以在化学工业上能广泛使用,从一九四七年以来就开始制造了。当然,在这方 Porous sintered material as a metal filter is concerned, in the industrial significance of more and more. As early as 1930, the bronze filter was made by powder metallurgy. Bronze filters are used in many ways because they are relatively simple to make from metal bronze and are corrosion and heat resistant. Non-alloy steel or corrosion-resistant steel filters, which are widely used in the chemical industry due to their corrosion resistance, have been manufactured since 1947. Of course, on this side
