我公司在学习兄弟单位经验的基础上,采用聚醋酸乙烯乳液大白浆刷浆,一年多来已在各种不同条件(雨季、冬季、干湿墙面)下使用,大部份情况都较好,但也有一些墙面比较湿的栋号当时就出现了花班、起皮、掉面等质量问题。为了进一步了解这些栋号的浆活变化情况,我们于1974年底组织了有领导、技术人员、油工师傅参加的三结合调查小组,对有代表性的栋号进行了现场调查和座谈讨论。通过这次调查发现了一些问题,也找到一些原因,并摸索出做好乳液大白浆特别是湿墙刷浆的一些规律,现将这次调查情况简介如下。
On the basis of the experience of our brothers, our company has used polyvinyl acetate emulsion white pulp for more than one year under various conditions (rainy season, winter, dry and wet walls), and in most cases it is Well, but there are some buildings with relatively wet walls. At that time, there were quality problems such as flower classes, peeling, and falling faces. In order to further understand the changes in the slurry activity of these buildings, at the end of 1974, we organized a three-in-one investigation team with the participation of leaders, technicians, and oil engineers to conduct on-site investigations and discussions of representative buildings. Through this investigation, we found some problems, and also found some reasons. We have also found out some rules for doing a good job for the emulsion whitewash, in particular, the wet wall brushing. We will now introduce the investigation as follows.
