Hydrolyzed polyacrylonitrile ammonium (NH4-HPAN)
1.Properties and applications
This product is brown powder, soluble in water, aqueous solution was neutral.It has the following characteristics
1,Have good filtrate reducer effect on the drilling fluid,especially high pressure differential water loss
2,Good thermal stability
3,Can reduce drilling fluid viscosity
4,Can inhibit the ability of clay hydration and anti-collapse
5,With Good anti-sticking effect card
6,With salt contamination resistance and so on. Can be used anionic and zwitterionic-type water base drilling fluid system.

3.The use method and notice:
It can be used directly into the drilling fluid, but the added speed is not too fast to prevent the formation of large micelles; Also be dubbed in 1%~3% of the glue to join, its dosage is generally 0.5%~1.5 %.
4.Transportation and storage
The product is packaged in three-on-one bag with the net weight 25kg.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.
