一、前言 石棉水泥制品工业是国民经济建设中不可缺少的一门工业,其技术经济效益较高,在水泥制品工业的几十个行业当中优势明显。每万元固定资产实现利润一般是水泥制品的6—8倍;每万元产值利润和劳动生产率为其它制品的二倍。 石棉水泥制品其技术经济效益所以居于优势,主要是制品具有优质、高强、多功能的特点,因此被广为利用。 I. INTRODUCTION The asbestos cement product industry is an indispensable industry in the national economic construction. Its technical and economic benefits are relatively high. It has obvious advantages in dozens of industries in the cement product industry. The profit per ten thousand yuan in fixed assets is generally 6-8 times that of cement products; the profit of each ten thousand yuan in output value and the labor productivity are two times that of other products. The asbestos-cement products have advantages in terms of their technical and economic benefits, mainly because they are characterized by high quality, high strength and versatility, and are therefore widely used.
