Commonly used testing methods are introduced as follows:
Check whether it affects the strength and setting time: usually 1% of the cementitious material can be mixed with dissolved pump moisturizer to test the pump moisturizer Whether the agent solution affects the strength and setting time of concrete. The best pump moisturizer is one that does not affect the strength and setting time.
. Whether it is agglomerated, etc. A good pump moisturizer is one that can be completely dissolved and becomes transparent.
to toe to use a steel plate – Pour the prepared lubrication solution into it and pour it out in the shortest possible time. Weigh the quality of the wall-mounted pump lubricant. The one with a larger wall-mounted amount is better. Use your fingers to scrape the pump to moisten the lubricant. It is better to have a clear lubricating feeling.
Check the insoluble performance of the concrete: Take a good pump moisturizing tube liquid in the transparent cup, take a concrete pulp with a collapse of 220mm, about 1cm thick, stir with a strong glass stick 1 1 1 cm 1 minutes, it is better if the concrete does not dissolve into the pump moisturizer.
than have been in 100,000 sq ft. Take 50ml of the prepared lubricating fluid and place it on the outdoor cement floor, and check whether it is completely degraded within a week. A good pump moisturizer can be completely degraded without leaving any residue. </p
