n: A kind of anionic surface active agent. Mainly used as emulsifier of water base drilling fluid and improving temperature resistance capacity of drilling fluid in the deep well.

n: A kind of anionic surface active agent, usually used as frother, sometimes as the emulsifier in the foam drilling fluid. The symbol is AS.

n: 1. a negatively charged ion. 2. the ion in an electrolysed solution that migrates to the anode. See ion. Compare cation.

an ion with a negative charge.

process where a special resin exchanges chloride or hydroxide for contaminant anions such as fluoride, nitrate, sulfate and bicarbonate. Water purification is the primary use.

n: The additive which can change exchangeable negative ion which absorbed in the surface of the clay.

n: The process that the negative ion in the solution was absorbed in the surface of clay.

n: R-SO3-M (R is alkyl, M is cation),a kind of anionic surface active agent, mainly used as foaming agent of foam drilling fluid, for example alkane sulfonate.

a negatively charged surfactant. Normally water wets sands.

n: A kind of surface acting agent. It can produce hydrophobic negative ion.
