Carboxymethyl hmoov txhuv nplej siabyog ib qho anionic starch ether, ib qho electrolyte uas yaj hauv dej txias.Carboxymethyl starch ether yog thawj zaug tsim nyob rau hauv 1924 thiab yog industrialized nyob rau hauv 1940. Nws yog ib hom ntawm hloov starch, belongs rau ether starch, yog ib hom dej-soluble anion polymer compound.Nws yog tasteless, tsis muaj tshuaj lom, tsis yooj yim rau pwm thaum qhov kev hloov pauv ntau dua 0.2 yooj yim dua soluble hauv dej.

Nws siv los ua av nkos stabilizer, tus neeg saib xyuas dej nrog cov haujlwm ntawm kev txo cov kua dej (dej) poob thiab txhim kho cov coagulation stability ntawm av nplaum hais nyob rau hauv cov roj drilling av nkos.Thiab nws yog qhov zoo dua los nqa cov drilling cuttings.Tshwj xeeb tshaj yog haum rau high-salinity thiab high-PH Salinization zoo.

CMS muaj ntau yam khoom xws li thickening, suspension, dispersion, emulsification, bonding, dej tuav thiab tiv thaiv colloid. , thiab lwm yam. Nws yog dav siv hauv roj av, textile, tshuaj txhua hnub, luam yeeb, ntawv ua, kev tsim kho, khoom noj khoom haus, tshuaj thiab lwm yam kev lag luam, hu ua "industrial monosodium glutamate".

Carboxymethyl starch sodium (CMS) yog ib hom kev hloov pauv cov hmoov txhuv nplej siab nrog carboxymethyl etherification, qhov kev ua tau zoo dua li carboxymethyl cellulose (CMC), yog cov khoom zoo tshaj plaws los hloov CMC.Cov kua aqueous ntawm CMS yog ruaj khov thiab muaj kev ua tau zoo, uas muaj cov khoom zoo tshaj plaws. Kev ua haujlwm ntawm kev sib txuas, thickening, dej tuav, emulsification, ncua kev kawm ntawv thiab dispersion.CMS plays lub luag haujlwm tseem ceeb hauv kev txo cov dej poob thiab kev txhim kho cov coalescence stability ntawm av nplaum hais nyob rau hauv drilling kua raws li cov av nkos stabilizer thiab dej-retaining agent.CMS muaj me ntsis cuam tshuam rau cov yas viscosity ntawm av nkos tab sis muaj kev cuam tshuam zoo rau lub zog dynamic thiab shear force, uas yog qhov tsim nyog rau kev nqa cov drilling cuttings, tshwj xeeb tshaj yog thaum drilling ntsev muab tshuaj txhuam, uas tuaj yeem ua rau cov dej drilling ruaj khov, txo qhov poob, thiab tiv thaiv phab ntsa. collapse.Nws yog tshwj xeeb tshaj yog haum rau saline Wells nrog siab salinity thiab siab PH nqi.
