Production process of gypsum plaster board
The invention discloses a production process of a gypsum plaster board. The production process comprises the following steps: (1) selecting gypsum powder to prepare primary pulp; (2) preparing gypsum slurry; (3) extruding and forming the gypsum slurry; (4) conveying and drying; and (5) packaging finished products. The mesh number of a screen of the screen centrifugal machine is 80, the granularity of gypsum powder is more uniform through screening and impurity removal, the surface of a gypsum board is smoother, the uneven condition is not prone to occurring, the particles of the gypsum powder can be finer, the surface area of the gypsum powder can be increased, and therefore the binding power and strength of the gypsum board are improved; the pressure intensity is 30.8 MPa-35.8 MPa when the gypsum slurry is extruded, the formed gypsum plaster board is obtained, particles of the gypsum board can be more tightly combined together, so that the strength and hardness of the gypsum board are improved, and the particles of the gypsum board can be more uniformly distributed by controlling the pressure intensity when the gypsum board is extruded, so that the shrinkage rate of the gypsum board is reduced.
本发明公开了一种纸面石膏板的生产工艺，包括以下步骤：(1)选取石膏粉制备原浆；(2)石膏浆的制配；(3)石膏浆挤压成型；(4)传送烘干；(5)成品打包。本发明设置的筛网离心机筛网的目数为80目，过筛除杂使石膏粉的粒度更加均匀，使石膏板的表面更加平整，不易出现凹凸不平的情况，可以使石膏粉的颗粒更加细小，增加其表面积，从而提高石膏板的粘结力和强度；挤压石膏浆时压强为30.8MPa‑35.8MPa，得到成型的纸面石膏板，可以使石膏板的颗粒更加紧密地结合在一起，从而提高其强度和硬度，挤压石膏板时，控制压强可以使石膏板的颗粒更加均匀地分布，从而减少石膏板的收缩率。
