High-sodium-ion-content desulfurized gypsum plaster board and method for improving bonding grade
The invention provides a high-sodium-ion-content desulfurized gypsum plaster board and a method for improving a bonding grade. The plaster gypsum board is prepared from the following raw materials inparts by mass: 100 parts of desulfurized gypsum clinker; 60 to 75 parts of water; 0.5 to 10 parts of zeolite; 0.05 to 0.2 part of glass fibers; 0.2 to 1 part of retarder; and 0.2 to 1 part of starch.The preparation method comprises the following steps of: pretreating the zeolite and activating the zeolite; mixing the desulfurized gypsum clinker, glass fibers and treated zeolite to obtain a mixture; weighing the water, retarder and starch to prepare a mixed solution; uniformly mixing the mixture and the mixed solution to prepare gypsum slurry; and molding the gypsum slurry, performing solidifying, drying, laminating, edge sawing, edge sealing and packaging to obtain the gypsum plaster board. With the gypsum plaster board adopted, the technical problems that a gypsum plaster board preparedby taking high-sodium desulfurized gypsum clinker as a raw material is poor in dehydration property and cohesiveness can be solved, and under severe test conditions, the board core and surface protection paper of the gypsum plaster board are not stripped, so that the bonding effect of the gypsum plaster board is good.
本发明提供了钠离子含量高脱硫石膏纸面石膏板及提高粘结等级的方法，纸面石膏板原料按质量份计包括：脱硫石膏熟料100份、水60‑75份、沸石0.5‑10份、玻璃纤维0.05‑0.2份、缓凝剂0.2‑1份、淀粉0.2‑1份；所述制备方法包括，预处理沸石，将其活化；混合脱硫石膏熟料、玻璃纤维和经过与处理的沸石制得混合料；称量水、缓凝剂和淀粉，制得混合液；将混合料和混合液混合均匀，制成石膏料浆；将石膏料浆成型，凝固，干燥，合片，锯边，封边，包装，制得纸面石膏板。所述纸面石膏板解决了高钠脱硫石膏熟料作为原材料制备的纸面石膏板脱水性、粘结性差的技术问题，在苛刻的测试条件下，板芯与护面纸不剥离，粘结效果好。
