室内砂灰手工喷涂作业在建筑施工中已做过多次推广。多年来,由于手持喷枪作业存在着劳动强度高、灰雾大、作业条件差等缺点。因此,虽然喷涂作业具有效率高、质量好等优点,但也难以坚持下去。我公司总结了几年来在抹灰机械研制中的经验教训,集中力量对砂灰喷涂作了一番研究,认为应 Indoor sand ash manual spraying operations have been promoted several times during construction. Over the years, hand-held spray guns have had the disadvantages of high labor intensity, large fog, and poor operating conditions. Therefore, although the spraying operation has the advantages of high efficiency and good quality, it is difficult to stick to it. My company has summarized the experience and lessons learned in the development of plastering machines over the past few years and has concentrated its efforts on the research of sand ash spraying.
