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.

　　粉刷石膏基層處置也同樣重要，應先對基層外表的灰層，污垢，油污等清算潔凈。基層上凸凹局部和非預留孔洞等缺陷，應用同類資料處置平整結實。門窗框與邊縫處采用規則資料填實。粉刷石膏時要提早對基層灑水潮濕，抹灰時不得有明水。吸水率比擬大的墻體可先抹一層建筑膠水。

　　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.

　　粉刷石膏的料漿制備。脫硫石膏粉廠家石膏砂漿物料混合比例應適宜，引薦參照倡議配合比。一次投料量應在規則的時間內用完。初凝后料漿不得再次加水攪拌運用。先將水倒入攪拌桶，再倒入灰料，攪拌2——5分鐘，使料漿到達適宜的稠度，靜置5分鐘后再進行第二次攪拌后運用。

　　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應按抹灰面積所需求的量，不宜過多，要做到勤拌勤用，拌成的料漿要在初凝前用完，曾經初凝的料漿不得再次加水攪拌運用。以上內容是濟南石膏粉廠家為大家整理的，想要了解更多內容，歡迎訪問網站：http://www.sjzmx.cnThe mixing quantity of plastering gypsum should be in accordance with the requirement of plastering area. It should not be excessive. It should be used frequently.
