G30S is copolymerized by the AMPS, low molecular weight amides and so on. It dissolved in water quickly, therefore it can shorten on-site preparation of drugs dissolution time. Polymer molecular chains by reducing bundle concentrating slurry cake permeability. It reduce the slurry cake permeability by the aggregation of high polymer molecular chain.
1.G30S is polymerized by AMPS, low molecular amide, multi hydroxy carboxylic acid, auxiliary solvent,etc.
2.Fine particles, dissolved in water quickly.
3.Anti temperature property: 30~160ºC.
4.Anti salt property:fresh water until saturated brine.
5.Filtration property: <150ml API FL
6.Generally dosage range: 0.4 ~ 0.8% (BWOC).
7.Good compatibility with other additives.
8.Compatibility with cement: suitable for all levels of oil well cement.
9.The cement has good stability, and free liquid approaches zero.
10.The cement slurry thickening transition time is short, close to right angle thickening.
11.Suitable for low, conventional and high density cement slurry system of dry mixing or wet mixing.
