Carboxymethyl isitatshiyi-anionic starch ether, i-electrolyte enyibilika emanzini abandayo.I-Carboxymethyl starch ether yenziwa okokuqala ngo-1924 kwaye yaveliswa kwimizi-mveliso ngo-1940. Luhlobo lwesitatshi esilungisiweyo, yeyesitatshi se-ether, luhlobo oluthile lwe-anion polymer compound enyibilikayo emanzini.Ayinancasa, ayinatyhefu, akukho lula ukuyibumba xa iqondo lokutshintsha lingaphezulu kwe-0.2 ngokulula ngakumbi ukunyibilika emanzini.

Isetyenziswe njenge-stabilizer yodaka, i-arhente yokugcina amanzi kunye nemisebenzi yokunciphisa ulwelo (amanzi) ilahleko kunye nokuphucula ukuzinza kwe-coagulation yamasuntswana odongwe kudaka lokwemba ioli.Kwaye kungcono ukuthwala ukusika i-drilling cuttings.Ngokukodwa kufanelekile kwi-salinization ephezulu kunye ne-PH ephezulu ye-Salinization kakuhle.

I-CMS ineepropati ezahlukeneyo ezifana nokuqina, ukumiswa, ukusabalalisa, i-emulsification, i-bonding, ukugcinwa kwamanzi kunye ne-colloid yokukhusela. , njl. Isetyenziswa ngokubanzi kwi-petroleum, impahla, ikhemikhali yemihla ngemihla, icuba, ukwenza amaphepha, ukwakhiwa, ukutya, amayeza kunye namanye amacandelo oshishino, owaziwa ngokuba yi-"industrial monosodium glutamate".

I-Carboxymethyl starch sodium (CMS) luhlobo lwesitatshi esilungisiweyo esine-carboxymethyl etherification, ukusebenza ngcono kune-carboxymethyl cellulose (CMC), njengeyona mveliso ingcono yokuthatha indawo ye-CMC. imisebenzi yokubambisana, ukuqina, ukugcinwa kwamanzi, i-emulsification, ukumiswa kunye nokusabalalisa.I-CMS idlala indima ebalulekileyo ekunciphiseni ukulahleka kwamanzi kunye nokuphucula ukuzinza kwe-coalescence yamasuntswana odongwe kwi-drilling fluid njenge-stabilizer yodaka kunye ne-agent yokugcina amanzi.I-CMS inempembelelo encinci i-viscosity yeplastiki yodaka kodwa inefuthe elikhulu kumandla aguquguqukayo kunye ne-shear force, ekhuthaza ukuthwala ukusika ukusika, ngakumbi xa kusomba intlama yetyuwa, enokwenza ulwelo lokomba luzinze, lunciphise inani lelahleko, kwaye luthintele udonga. i-collapse.Ifanelekile ngokukodwa kwi-Saline Wells ene-salin ephezulu kunye nexabiso eliphezulu le-PH.
