NH4-HPAN (Ammonium Hydrolyze Polyacrylonitrile)
Description
Chemical name: Hydrolysis polyacrylonitrile ammonium salt
ItemNo.:NH4-HPAN
NH4-HPAN is a kind of proved drilling fluid additives which can be widely applied and has a lot of advantages.
Product features
The product of hydrolysis polyacrylonitrile ammonium salt NH4-HPAN is light yellow or brown powder. Soluble in water. This product has higher ability of de-filtration in fresh water or salt water. Apparent viscosity can be controlled at lower levels.
Usage and function
1. Reduce the water loss of the mud especially high pressure water loss.
2. Better thermo stability.
3. Excellent mud rheological property.
4. Have a certain ability to inhibit the clay from hydrating and resist landslide.
5. Have better effect of antiseizing.
6. Have a certain ability of salt and calcium resistance.
