Hydrolysis polyacrylonitrile-Sodium
Introduction:
The product of Na-HPAN is light yellow to brown solid powder and granule, it has strong salt resistance. In salt water the ability of de-filtration especially outstanding. In addition, the product has an ability of temperature resistance. At the same time, it can improve the effective viscosity of drilling fluid. It is a kind of good treating agent of drilling in salt layer on page.
