建筑物用干粘石外饰面,在人们的印象里有石粒分布不均匀,脱粒严重等缺陷。然而,上述缺陷是可以通过施工工艺的改进而加以解决的。1982年以来,邵阳市先后在十六幢建筑物的外饰面施工中,采用了机械喷石工艺,饰面面积两万多平方米,饰面质量不仅克服了脱粒和石粒分布不匀的缺陷,而且饰面平整度与色泽都获得了良好的效果。一、机具选择我们先后采用了手持式喷斗和PSQ_2-1型气动喷石机。两者比较,前者料斗容积小,需专人喂石子,且操作者手举喷斗作业,劳动强度大,使用不太方便,对阴角深处喷斗无法喷石。而后者操作轻巧灵活,易于掌握,为提高机喷质量提供了有利的作业条件。因此我们选用了PSQ_2-1型气动喷石
The dry sticky stone exterior of the building has been found in people’s impressions as having uneven distribution of pebbles and severe threshing. However, the above defects can be solved through the improvement of the construction process. Since 1982, Shaoyang City has used mechanical spray stone technology in the construction of exterior decoration of 16 buildings. The decorative surface area is more than 20,000 square meters. The quality of the facing surface not only overcomes the uneven distribution of threshing and stony grains. Defects, and the smoothness and color of the finishes have achieved good results. First, the choice of tools We have adopted a handheld sprayer and PSQ_2-1 pneumatic sprayer. Comparing the two, the former has a small hopper volume and needs someone to feed the stone. The operator uses the hand to lift the bucket to work. It is labor-intensive and inconvenient to use. The latter is light and flexible, easy to handle, and provides favorable operating conditions for improving the quality of jetting. Therefore, we chose PSQ_2-1 pneumatic spray stone
