How to operate wet concrete sprayer correctly? The wet sprayer sprays concrete to uniformly mix the aggregate, cement and water according to the design proportions. The mixed concrete is pressed to the sprayer with a wet sprayer, and then sprayed on the sprayer after filling with an accelerating coagulant. The quality of wet shotcrete is easier to control.
When the wet sprayer sprays the work, the water-cement ratio and the amount of the quick-setting agent should be strictly controlled. After spraying, the surface of the sprayed layer is smooth and smooth, no dry spots or slip flows, and when the wet sprayer sprays concrete, the spiral can be screwed. Moving ahead, you can also use S-shaped reciprocating movement.
When the concrete wet spray gun is sprayed, it must be opened and re-opened. When shutting down, the shut-off device must be closed and closed again to prevent the cement slurry from entering the gas path. After the spraying, the gas path must be opened at the end and the nozzle should be removed and retracted. In order to ensure the liquid suction capacity of the quick-setting coagulant pump, the coagulant pump gas path should be opened first, and then to the main gas path of the spray head. After the spraying is completed, the quick-setting accelerator should be pumped for more than one minute to clean the pipeline to prevent the residual accelerator from blocking the pump.
