一、为了节约木材,我们根据建筑技术革新活页资料第四期的一文“石膏锯末板”进行试制,并作了部分改进,想以此来代替灰板条平顶及隔墙,并作成表面光滑涂色的天棚平顶。二、我们工地制作情况简介:1.工具①木模(70×40×1)(50×50×1)(尺寸是根据平顶筋间距而定)②铁镐、木③拌板(木制、铁制均可。)④台称。2.材料①石膏——石膏的原料是带两个分子结晶水的硫酸钙(Ca So_4 2H_2O)生石膏、生石膏经烘烧磨细即成熟石膏我们采用的是速凝熟膏粉。②锯末——一般工地均有但需经过
First, in order to save wood, we conducted trial production of the “cast gypsum board” in the fourth issue of the building technology innovation flyer data sheet, and made some improvements to replace the gray flat top and partition walls with a smooth surface. Painted ceiling flat roof. Second, we site production situation Description: 1 tool 1 wooden mold (70 × 40 × 1) (50 × 50 × 1) (size is determined according to the pitch of the top plate) 2 iron, wood 3 plate (wooden , iron can be.) 4 said. 2. Material 1 Gypsum - The raw material for gypsum is calcium sulfate (Ca So 4 2 H 2 O) gypsum with two molecules of crystal water, and raw gypsum is finely ground and mature gypsum. We use quick-cooked cooked plaster powder. 2 Sawdust - common site but needs to pass
