Polyanionic cellulose (PAC) thiab sodium carboxymethyl cellulose (CMC) yog ob hom cellulose ethers uas muaj cov qauv tshuaj thiab cov khoom zoo sib xws, tab sis txawv ntawm qee qhov tseem ceeb.

PAC yog cov dej-soluble cellulose ether uas muaj kev hloov pauv siab, txhais tau hais tias ntau pawg carboxymethyl txuas rau hauv cov pob txha cellulose. PAC feem ntau yog siv los ua cov viscosifier thiab cov kua dej poob qis hauv cov roj drilling kua vim nws cov dej tuav tau zoo, ruaj khov, thiab cov khoom tuab.

CMC, ntawm qhov tod tes, yog cov dej-soluble cellulose ether uas yog dav siv los ua cov thickener, binder, thiab stabilizer nyob rau hauv ntau yam lag luam, nrog rau cov khoom noj, tshuaj, tshuaj pleev ib ce, thiab cov ntawv tsim. CMC yog tsim los ntawm cov tshuaj tiv thaiv ntawm cellulose nrog monochloroacetic acid los qhia carboxymethyl pawg mus rau hauv cov pob txha cellulose. Qhov kev hloov pauv ntawm CMC yog qis dua li ntawm PAC, tab sis nws tseem muab cov dej khaws cia zoo, ruaj khov, thiab cov khoom thickening.

Txawm hais tias ob qho tib si PAC thiab CMC yog cellulose ethers nrog cov khoom zoo sib xws, lawv txawv ntawm qee qhov tseem ceeb. Piv txwv li, PAC feem ntau yog siv nyob rau hauv cov roj drilling kev lag luam vim nws qib siab ntawm kev hloov pauv thiab cov kua dej zoo txo ​​qis, thaum CMC yog siv nyob rau hauv ntau qhov kev lag luam vim nws qib qis ntawm kev hloov pauv thiab ntau yam hauv ntau daim ntawv thov.

Zuag qhia tag nrho, PAC thiab CMC yog ob qho tib si tseem ceeb ntawm cellulose ethers nrog cov khoom tshwj xeeb thiab kev siv. Thaum PAC feem ntau yog siv nyob rau hauv cov roj drilling kev lag luam, CMC muaj ntau yam kev siv nyob rau hauv ntau yam lag luam vim nws versatility thiab qis dua kev hloov.
