WG5C Automatic gypsum plaster machine

  

Compared with the traditional plastering process, the automatic spraying process has high spraying pressure, strong adhesion, firm bonding, no empty drums, cracks and shedding, which can improve the quality of the project. In addition, the mechanical spraying construction speed is fast, the work efficiency is high, the labor can be reduced, the cost is reduced, and the market prospect is broad. The promotion and application of this product can consume a large amount of desulfurized gypsum waste residue and has good social benefits.

(1) Desulfurization gypsum-based spray gypsum mortar is mixed with vitrified microbeads with a total mass of 3.0%, which can reduce the density of mortar, improve the workability and reduce the loss of spraying equipment. When the cellulose ether content is 0.20%, the water retention rate and tensile bond strength of the spray gypsum mortar are good. The blending ratio of 0.03%-0.07% starch ether can improve the anti-sag ability and lubricity of the material, make the operation smoother, improve the operation performance of the material, and meet the construction requirements.

(2) Through the test, the production formula of desulfurization gypsum-based spray gypsum mortar is determined as follows: desulfurization gypsum 50%, light aggregate vitrified microbead 3.0%, fine sand 46.4%, water retention agent cellulose ether 0.20%, gypsum retarder 0.25%, the thixotropic starch ether 0.05%. The initial setting and final setting time of the prepared desulfurized gypsum-based gypsum mortar were 85 and 104 min respectively, and the flexural and compressive strengths were 2.3 and 4.7 MPa, respectively. The tensile bond strengths of concrete slabs and aerated concrete blocks were respectively 0.45, 0.37 MPa.

(3) Desulfurization gypsum-based gypsum mortar construction process is simple, the construction effect is good, and the desulfurization gypsum waste residue can be consumed in a large amount, and the market prospect is broad.
