The lubrication effect of the concrete pump truck lubricant after it forms a gel-like liquid is generally achieved through the following four aspects:
1. Reduce the adsorption of water by the pipe wall. The lubricant after mixing with water becomes gel-like. The gel-like liquid adheres to the inner wall of the pipe, preventing the pipe from absorbing water from the concrete and maintaining the flow of the concrete. state.
2. The low viscosity of the gel-like liquid reduces the viscous resistance of the pipe wall to the concrete.
3. As the concrete moves forward in the pumping pipe, the linear organic polymer compound chains of polyacrylamide stretch along the pipe wall and form a continuous and uniform layer. Lubricating film, concrete flows in the lubricating film.
4. The viscous resistance of the pumping pipeline is reduced, so the pump pressure becomes smaller, and the fresh concrete can be pumped smoothly. </p
