The finished products should be protected before plastering. The doors and windows can be protected by wood plate or plastic glue paper; the air of the building can be protected by plastic cloth; the pipes, fire-proof boxes, electrical switch boxes, wire boxes, embedded parts and equipment, railings and handrails installed by desulfurization gypsum powder factories can be protected by plastic cloth.

　　粉刷石膏基层处置也同样重要，应先对基层外表的灰层，污垢，油污等清算洁净。基层上凸凹局部和非预留孔洞等缺陷，应用同类资料处置平整结实。门窗框与边缝处采用规则资料填实。粉刷石膏时要提早对基层洒水潮湿，抹灰时不得有明水。吸水率比拟大的墙体可先抹一层建筑胶水。

　　It is equally important to dispose of gypsum base course. First, the ash layer, dirt and oil dirt on the surface of base course should be cleared and cleaned. Defects such as convex and concave parts and non-reserved holes on the base are treated with the same kind of data to be smooth and firm. Rule data are used to fill in the door and window frames and edge seams. When plastering gypsum, it is necessary to sprinkle water and humidity on the grass-roots as early as possible, and no clear water is allowed when plastering. A layer of building glue can be applied to the wall with a large water absorption ratio.

　　粉刷石膏的料浆制备。脱硫石膏粉厂家石膏砂浆物料混合比例应适宜，引荐参照倡议配合比。一次投料量应在规则的时间内用完。初凝后料浆不得再次加水搅拌运用。先将水倒入搅拌桶，再倒入灰料，搅拌2——5分钟，使料浆到达适宜的稠度，静置5分钟后再进行第二次搅拌后运用。

　　The slurry preparation of plastering gypsum. The mixing proportion of gypsum mortar materials in desulfurization gypsum powder factories should be appropriate. The recommendation refers to the recommended mixing proportion. The quantity of one-time feeding should be used up within the regular time. The slurry after initial setting should not be mixed with water again. First pour the water into the mixing barrel, then pour the ash, mix for 2 - 5 minutes, so that the slurry reaches the appropriate consistency, and then stand for 5 minutes before mixing for the second time and then use.

　　粉刷石膏每次拌料量应按抹灰面积所需求的量，不宜过多，要做到勤拌勤用，拌成的料浆要在初凝前用完，曾经初凝的料浆不得再次加水搅拌运用。以上内容是济南石膏粉厂家为大家整理的，想要了解更多内容，欢迎访问网站：//www.gochiism.comThe mixing quantity of plastering gypsum should be in accordance with the requirement of plastering area.
