北方冬期施工内墙抹灰往往采用煤火炉来保证室内的操作温度,因此,常常造成内墙面、顶棚煤烟污染。如采用常规粉刷,泛黄现象严重。我公司几年来的实践证明:用粘土浆处理内抹灰的烟熏污染,既经济又能保证质量。工艺过程为:将煤烟熏黑的墙面清扫后打砂纸,较重地方可用水洗→牯土浆粉刷一遍,严重时可粉刷两遍→刷 In the northern winter construction, interior wall plastering is often performed using a coal fired stove to ensure the indoor operating temperature. Therefore, the inner wall surface and ceiling coal smoke pollution is often caused. Such as the use of conventional paint, yellowing serious. The practice of our company over the past few years has proven that the use of clay slurry to treat smoke pollution from internal plastering is both economical and quality assured. The process is as follows: After cleaning the smoked black wall, the sandpaper will be used. The heavier place can be washed with water → The rammed soil can be brushed again. When it is severe, it can be brushed twice. → Brush
