加拿大建筑材料公司(CBM)近来在安大略省奥沙瓦新建成投产了两条每小时生产2万块彩色混凝土砖的全自动生产线,巩固了其在北美彩色混凝土砖制砖业中的主导地位。彩色混凝土砖的销售量近年来稳步增长,1986、1987年两年销售量远超过1亿块。自二次世界大战以来,由于安大略省住宅建筑业的繁荣兴旺,彩色混凝土砖日益流行。目前,彩色混凝土砖的销量约占安大略省砖市场的30％,CBM彩色混凝土砖的市场份额约占50％。其生产过程,从原材料、颜料计量、搅拌开始,直到成型、养护、体积计量、堆垛都是由计算机控制的高度自动化的生产工艺完成的。其主要生产过程大致如下:
Canadian Construction Materials (CBM) has recently completed the production of two fully automated production lines that produce 20,000 colored concrete blocks per hour in Oshawa, Ontario, consolidating its dominant position in the North American color concrete brick brick industry. The sales volume of color concrete bricks has steadily increased in recent years. In 1986 and 1987, the sales volume in two years exceeded 100 million. Since World War II, colored concrete bricks have become increasingly popular due to the booming residential construction industry in Ontario. At present, the sales volume of color concrete bricks accounts for about 30% of the Ontario brick market, and the market share of CBM color concrete bricks accounts for about 50%. The production process begins with raw materials, pigment metering, and mixing until molding, curing, volumetric metering, and stacking are all accomplished by highly automated computer-controlled production processes. Its main production process is roughly as follows:
