Product Description
As the aggregated molecule chain of water soluble polymer can decrease the mud cake permeability of mud slurry, Introducing multi-functional groups in polymer that enhance the ability of anti-high temperature and anti-salt. In addition, by adjusting the molecular weight, impart the fluid loss additive the performance of thickening, suspension.
Characteristics
JKN-FL-91L is gained by the polymerization of low molecular weight amides, carboxylic acid.
JKN-FL-91L is a kind of viscous liquid.
Anti-temperature range: 30℃-120℃.
Salt range: fresh to saturated water.
Filtration property: ＜100mlAPI FL.
Solubility: soluble .
Dosage: 4%-6%(BWOC).
Solubility with cement: applicable for any cement classes.
Stability: free water approach zero.
Thickening time: thickening curve approach a right-angle.
Density range: any density of cement slurry system.
It has a retarding effect, and when at medium and low temperature conditions, utilizing with the early strength agent and coagulant can adjust thickening time.
