Study on the Mixing Ratio of Lubricating Pump Agent

Principles for selecting components of lubricant:

(1) First, substances with high surface tension and viscosity should be used to improve the adhesion of the lubricant inside the pump tube;

　(2) The lubricating agent should have a large solubility to facilitate use at the construction site;

　(3) The lubricating agent should have substances that can increase the slipperiness of water;

(4) The components of the lubricating agent should have good compatibility; and there should be no harm to concrete quality and the environment;

(5) Each component should be reasonably priced and come from a wide range of sources , to facilitate promotion.

Among the many surface-active substances, we selected component A with high viscosity, component B that can improve the wetting and lubricating effect of water on the pump and pump tube, and component C that can increase the dissolution rate of substance A. substance. Find the optimal ratio of the three components through orthogonal experiments. The above three substances A, B, and C are mixed in a certain proportion to prepare a concrete lubricating agent.
Performance of concrete pump lubricant:

(1) Pump lubricant: water (normal temperature) = 1: 80 ~ 1: 100 can be dissolved after 5 ~ 10 minutes of stirring.

(2) The solution is a colorless, transparent, viscous liquid, weakly alkaline, and feels slippery.

(3) The main raw materials of wetting agent can be used to prepare concrete admixtures. A small amount of its solution mixed into concrete will have no effect on the strength. </p
