自本世纪30年代欧洲开发出有上级双轴搅拌挤出和下级螺旋挤出成型的双级真空挤泥机以来,几乎全部取代了原来的单级挤泥机.近年来国内开始出现单级真空挤泥机的产品,产品销售前景颇好.接着就有不少厂家相继设计制造单级真空挤泥机,大有雨后春笋之势.对于单级真空挤泥机的出现和发展,应该如何评价?本文想就此谈几点看法.
Since the 1930s in Europe developed a two-stage vacuum squeezer with superior biaxial mixing extrusion and lower-stage screw extrusion, almost completely replaced the original single-stage squeezer. In recent years, domestic single-stage vacuum has emerged. The product of mud squeezer has a good prospect of product sales. Then there are many manufacturers have designed and manufactured single-stage vacuum squeezers one after another. It has great potential for springing up. How to evaluate the emergence and development of single-stage vacuum squeezers? This article would like to talk about a few points on this.
