目前日本在抹灰工序中,材料筛选和混合料的搅拌机械化程度已接近100%,但材料运送(由搅拌机至抹灰地点)及抹灰仍有很大的体力劳动。利用灰浆泵解决灰浆的运送和抹灰已开始实用,但最后的饰面还有待解决。日本学习西德和美国的经验,从1965年到1966年开始正式使用灰浆泵,经六年全国估计已有大小灰浆泵二千台。 At present, in the plastering process in Japan, the material screening and the mixing and mechanization degree of the mixture are close to 100%, but there is still a lot of manual labor in the material transportation (from the mixer to the plastering site) and the plastering. The use of the mortar pump to solve the mortar transport and plastering has begun to be practical, but the final finish has yet to be resolved. Japan’s experience in learning West Germany and the United States began with the use of mortar pumps from 1965 to 1966, and it was estimated that there were 2,000 mortar pumps of a size for six years.
