concrete pump truck lubricant is mainly composed of polymer materials, usually white powdery solid. at room temperature, the lubricant can quickly dissolve in water to form a viscous liquid.
the main component of concrete pump truck lubricant is polyacrylamide, which is a water-soluble linear high molecular polymer polymerized from acrylamide monomer. the polymer molecules form bridge adsorption with the suspended particles dispersed in the solution, which has a strong flocculation effect. when the concentration is high, there are a large number of chain-to-chain contact points in the solution, making the polyacrylamide solution gel-like. this gel-like liquid is a lubricating film composed of countless micro-anions, which can fully lubricate the inner surface of the concrete pumping pipe.
