摘要： There are provided a method of recovering a base paper for gypsum board for continuously and efficiently recovering a base paper for gypsum board from a waste material of gypsum board including a gypsum core and the base paper for gypsum board adhering thereto. The method of recovering a base paper for gypsum board includes steps of breaking the waste material of gypsum board, separating a gypsum component and a paper piece of the base paper for gypsum board from the broken waste material of gypsum board, and washing the separated paper piece with water using a rotary drum-type washing device so as to eliminate a gypsum component adhering to the paper piece.
摘要翻译：提供了一种回收用于石膏板的原纸的方法，用于从包括石膏芯的石膏板的废料和用于石膏板的原纸粘附到石膏板的废料上连续有效地回收用于石膏板的原纸。回收石膏板原纸的方法包括：从破碎的石膏板废料中分解石膏板的废料，石膏组分和石膏板原纸的纸片，分离纸使用旋转滚筒式洗涤装置将其与水一块，以消除粘附在纸张上的石膏成分。

摘要： The present invention provides a method for manufacturing a calcined gypsum wherein the mixing water amount is reduced and the setting time does not increase. As a raw gypsum is compounded with a carboxylic acid-type material and calcined, a calcined gypsum can be manufactured wherein the mixing water amount is small and the setting time does not increase. Furthermore, a regular gypsum board can be manufactured without reducing the productivity of the gypsum board even if a large quantity of recycled gypsum causing increase of the mixing water amount is used as a raw gypsum, because the mixing water amount is small and the setting time does not increase for the calcined gypsum manufactured as described above.
摘要翻译：本发明提供一种制造煅烧石膏的方法，其中混合水量降低，凝固时间不增加。将原料石膏与羧酸型材料混合并煅烧，可以制造出混合水量小且凝固时间不增加的煅烧石膏。此外，由于混合水量小，凝固时间短，因此即使将大量的混合水量增加的回收石膏用作原料石膏，也可以不降低石膏板的生产率而制造普通的石膏板对于如上所述制造的煅烧石膏不增加。
