Formula and detection method of pump truck lubricant

The formula of concrete pipe wetting agent can be clearly explained from the aspects of the composition, selection and function of the developed product.

1. Selection rules for concrete runner formula ingredients:

1. Purposefully selecting materials with larger surface tension and viscosity can improve the performance of concrete pipes in pump pipes. Adhesion;

2. The solubility of concrete pipes should be large to facilitate use at the construction site;

3. Lubricant should be added to the concrete pipetting agent to increase the humidity of the water;

4. The components of the concrete pipetting agent should be compatible. At the same time, it should not cause harm to the quality of the concrete and the use environment;

5. In order to facilitate the smooth sales of concrete pipes, various components of the pipette formula at appropriate prices should be purchased.

2. Concrete pipeline agent product performance: 1. Pipeline agent: water (normal temperature) = 1:80-1:100, stir for 5-10 minutes to dissolve. 2. The solution is a colorless, transparent, slippery, viscous liquid with a weakly alkaline pH. three. The main raw materials of the tubular runner can be used to prepare concrete admixtures, and the solution has little effect on the strength of concrete.

3. Outline of the formula of concrete pipe agent: Select the highly viscous component a among the selected surfactants, and at the same time take into account the ability to increase the wetting and wetting of the pump and the pump pipe by water. Component b for lubrication. There is also a c component that can quickly dissolve this component. Through orthogonal experiments, the optimal ratio of the three components was determined. The above three substances a, b, and c are mixed in a certain proportion to form a concrete tube.

The testing methods of wetting agents mainly include solubility testing, pipeline energy testing, concrete intolerance testing, environmental protection testing, etc.

Check the solubility: add 500 grams of water to 5 degrees, take 5 grams of tube wetting agent, stir for 1 minute, 3 minutes, stir for 1 minute, check whether the pump pipe threading agent is completely dissolved and agglomerated, thereby checking the pump Whether the pipe threading agent has completely dissolved the agglomerates, etc. Completely soluble and transparent, it is a good pump lubrication agent.

Check the lubrication ability: Take a steel pipe with a diameter of 150mm×25cm and seal the other end. Pour the prepared lubrication solution into it and pour it out in the shortest possible time. Weigh the pump operation and lubrication fluid quality and wall volume, the more wall volume the better. It’s best to use your fingers to scrape the pump and apply moisturizer.

Concrete insolubility check: use a transparent beaker to pump 200 ml of wetting agent solution, a concrete slurry with a slump greater than 220 mm, about 1 cm thick, stir with a glass rod for 1 minute, the concrete is insoluble in the pumped Wetting agents are best.                                       Check environmental protection. The pump running pipe should be non-toxic and smell-free. Take 50 ml of the completed pump solution and place it on the outdoor cement floor. Check for complete degradation within a week. Yulong pipe lubricant is a good reagent for pump running pipes and can be completely degraded without leaving any residue. </p
