Cov khoom
Xanthan Gum (XC Polymer)
Xanthan cov pos hniavnrog cov cuab yeej tshwj xeeb rheological, dej solubility zoo, ntawm thermal stability thiab acid thiab alkali, thiab ntau yam ntsev muaj kev sib raug zoo, xws li thickener, suspending agent, emulsifier, stabilizer, tuaj yeem siv dav hauv zaub mov, roj, tshuaj thiab lwm yam. ntau tshaj 20 kev lag luam, tam sim no yog lub ntiaj teb cov khoom loj tshaj plaws thiab muaj ntau yam ntawm USES microbial polysaccharides.
Roj Drilling xanthan cov pos hniav yog ib hom kev ua tau zoo, zoo, ib puag ncig tus phooj ywg roj drilling av nkos additives, siv ntau yam, qhov kub thiab txias, acid, alkali, ntsev, nrog lub siab ntev, tuaj yeem txhim kho lub peev xwm ntawm cov khoom raug tshem tawm thiab permeability. ntawm cov slurry, txo lub siab nyob rau hauv tus txheej txheem ntawm drilling, stabilize borehole phab ntsa, txo qhov kev puas tsuaj rau lub reservoir, txhim kho efficiency ntawm drilling, workover, zoo ua hauj lwm tiav.Nws muaj cov av nkos zoo ntxiv uas ruaj khov rau lub sijhawm ntev nyob rau hauv saturated brine thiab kub ntawm 85.Yog li ntawd, nws yog ib qho zoo tagnrho roj hloov chaw rau kub thiab siab ntsev roj teb. Xanthan gum yog tam sim no lub thoob ntiaj teb txheej ntawm thickening, ncua kev kawm ntawv. , emulsification, stability nyob rau hauv ib qho.Qhov zoo tshaj plaws bioadhesive.
