Phosphogypsum-based mixed mortar wall spraying process

Abstract

The invention provides a phosphogypsum-based mixed mortar wall spraying process. The process comprises the steps that phosphogypsum powder is prepared; mixed mortar is prepared; a wall base face is treated; a spraying machine is used for spraying the mixed mortar along a proper movement track; multiple coating layers are sequentially formed on a base face in a stacked mode; and impurities on the ground of a construction site are removed after the coating layers are leveled and calendered. After the technical scheme of the invention is adopted, the mixed mortar contains a flame-retardant material, so that the flame-retardant and fireproof performance of the wall body is improved and fire hazard is reduced; phosphogypsum is used as a cementing material of the mixed mortar, the application field of ardealite is widened; the spray gun moves along a reasonable path in the spraying operation process, operation of workers is facilitated, mixed mortar is sprayed evenly, the construction efficiency is improved; in addition, the interruption situation of spraying operation is handled in time, safe and stable operation of equipment is guaranteed, and the service life of the construction equipment is prolonged.

Description

technical field [0001] The invention belongs to the technical field of construction spraying construction, and in particular relates to a phosphogypsum-based mixed mortar wall spraying process. Background technique [0002] With the development of the economy, various high-rise buildings have sprung up, and spraying the walls of these high-rise buildings is conducive to optimizing the environment and giving people a beautiful feeling. However, due to the different structures and shapes of various buildings in the city, some difficulties have been caused to the construction of sprayed walls. Most of the existing outdoor medium and low wall constructions still use manual construction. Construction method, the quality of spraying on the outer surface of the wall is difficult to control, and the formed coating layer is prone to surface unevenness, hollowing, falling off, cracking, water seepage and unstable performance when exposed to heat. The reasons for these phenomena are la...

However, due to the different structures and shapes of various buildings in the city, some difficulties have been caused to the construction of sprayed walls. Most of the existing outdoor medium and low wall constructions still use manual construction. Construction method, the quality of spraying on the outer surface of the wall is difficult to control, and the formed coating layer is prone to surface unevenness, hollowing, falling off, cracking, water seepage and unstable performance when exposed to heat. The reasons for these phenomena are largely due to The spraying construction operation process is not standardized. During the spraying construction, the distance between the spray gun port and the surface to be sprayed, the spray gun moving speed and other process parameters are improperly selected.
