Anti-collapse viscosity break Fluid Loss Additive
1. Properties and applications
This product is modification of humic acid and cationic graft copolymer.The modification of humic acid improves the ability of de-filtration and viscidity reduction besides its humic acid function .With the introduction of cation components , the anti-collapse effect has been strengthened. This product fits the fresh water drilling fluid system, notably reducing the swelling rate of bentonite and high temperature and pressure filtration loss .
2. Technological Index

3.Use method and notice
The product can be added directly into the drilling fluid, but not too fast in adding process lest the gel balls come into being. We advise mix up 5 to 10% gel liquid and then add it to the drilling liquid with amount 1% to 3%.
4.Transportation and storage
The product is packaged in three-on-one bag with the net weight 25kgand the inaccuracy is±0.25kg. It should be put into dried storage room lest it is polluted or dampened. Pay attention to anti-dampness,anti-exposure and bag breakage during the transportation.
