Applications
ZOC-P81L solids-free suspending additive could be used to modify the stability of low-density cement slurries, without Extenders like microspheres, the slurries be equal or greater than 1.2SG could be obtained. The agent also has a strong effect on the hydration of cement slurries, which makes a higher compressive strength.
Benefits
l Can prepare cement slurries density equal or greater than 1.2SG without extender like microsphere.
l A strong effect on slurries stability.
l Can accelerate cement slurries hydration, which makes a higher compressive strength.
l Well-adapted with most of common well cementing additives.
l Convenient to cementing work on the sea due to the liquid form.
l Can obtain higher compressive strength without extenders.
Features
l Significantly greater suspending characteristics than previously available suspending additives.
Normal use of range:
l Temperature: ＜60℃
l Concentration: 50%
Usage Restrictions:
If the temperature is than 60℃, the thickening time and the compressive strength could be abnormally decreased.
