Pipe lubricant is a new technology in modern pump lubricating technology. It is a polymer material used to lubricate pump pipes instead of traditional mortar. Since it will be in direct contact with concrete during actual use, when selecting a lubricant product, we must not only consider its lubrication performance, but also whether it has any impact on the quality of the concrete. So how can we know the quality of the lubricant? Below we will give a simple explanation on how to use a simple method to judge the quality of the lubricant.
Method/steps
Take a clean container (capacity meets the requirements of more than 150mL ), a medium-sized stirring rod, which can be an object such as chopsticks.
Take 100ml of pure water
Weigh a certain amount of moisturizer product (generally 1 gram)
Pour 100ml of pure water into the prepared container - stir the water with a stirring rod - add the moisturizer product slowly and evenly Pour into the container - stir while pouring - continue stirring for about 1 minute; then, we let the stirred solution stand for 3-5 minutes - stir again
Result Judgment:
1. Observe the dissolution speed of the lubricating agent during the above experimental process, and the one with the faster dissolution speed is the best.
2. Observe the solubility of the lubricating agent during the above experimental process. The one with high solubility or complete dissolution is the best product.
3. Use a stirring rod to stir the lubricant, the one with higher viscosity is the best product; use the stirring rod to pull the solution, and the thicker one will be used. The longer ones are excellent products.
4. Use PH test paper to test the pH value of the solution. A neutral solution with a pH value of about 7 is the ideal product.
5. Pour the solution into a clean place in an outdoor environment. After a week, observe whether the poured solution is completely degraded. The one with complete degradation is considered a high-quality product. . </p
