I-sodium carboxymethyl cellulose (i-CMC-Na ngamafuphi) iyinhlanganisela ye-polymer ebalulekile encibilika emanzini futhi isetshenziswa kakhulu oketshezini lokumba uwoyela. Izakhiwo zayo eziyingqayizivele ziyenza ibe yingxenye ebalulekile ohlelweni loketshezi lokumba.
1. Izakhiwo eziyisisekelo ze-sodium carboxymethyl cellulose
I-sodium carboxymethyl cellulose i-anionic cellulose ether ekhiqizwa i-cellulose ngemva kokwelashwa kwe-alkali ne-chloroacetic acid. Isakhiwo sayo samangqamuzana siqukethe inani elikhulu lamaqembu e-carboxymethyl, okwenza kube nokuncibilika kwamanzi okuhle nokuzinza. I-CMC-Na ingakha isixazululo se-viscosity ephezulu emanzini, esinokuqina, ukuqiniswa kanye nezakhiwo zefilimu.
2. Ukusetshenziswa kwe-sodium carboxymethyl cellulose oketshezini lokumba
I-Thickener
I-CMC-Na isetshenziswa njenge-thiener oketshezini lokumba. Umsebenzi wayo oyinhloko ukukhulisa i-viscosity yoketshezi lokumba futhi ithuthukise ikhono layo lokuthwala ukusikwa kwamadwala nokusika ukusikwa. I-viscosity efanele yoketshezi lokumba ingavimbela ngempumelelo ukubhidlika kodonga lomthombo futhi igcine ukuzinza komthombo.
Isinciphisi sokulahlekelwa kwamanzi
Phakathi nenqubo yokumba, uketshezi lokumba luzongena ezimbotsheni zokubunjwa, lubangele ukulahlekelwa kwamanzi oketshezini lokumba, olungachithi nje kuphela uketshezi lokumba, kodwa lungabangela nokuwa kodonga lomthombo kanye nokulimala kwedamu. Njengesinciphisi sokulahlekelwa uketshezi, i-CMC-Na ingakha ikhekhe lokuhlunga eliminyene odongeni lomthombo, inciphise ngempumelelo ukulahlekelwa kokuhlunga koketshezi lokumba futhi ivikele ukwakheka nodonga lomthombo.
Okokugcoba
Phakathi nenqubo yokumba, ukungqubuzana phakathi kwe-drill bit kanye nodonga lomthombo kuzokhipha ukushisa okukhulu, okuholela ekugugeni okukhulayo kwethuluzi lokubhoboza. I-lubricity ye-CMC-Na isiza ukunciphisa ukungqubuzana, ukunciphisa ukuguga kwethuluzi lokubhoboza, futhi kuthuthukise ukusebenza kahle kokumba.
Isiqinisi
Uketshezi lokumba lungase luntante noma luwohloke ngaphansi kwezinga lokushisa eliphezulu kanye nokucindezela okukhulu, ngaleyo ndlela kulahlekelwe umsebenzi walo. I-CMC-Na inokusimama okuhle kokushisa nokumelana nosawoti, futhi ingagcina ukuzinza koketshezi lokumba ngaphansi kwezimo ezinzima futhi yandise impilo yayo yesevisi.
3. Indlela yokusebenza ye-sodium carboxymethyl cellulose
Ukulungiswa kwe-viscosity
Isakhiwo samangqamuzana e-CMC-Na siqukethe inqwaba yamaqembu e-carboxymethyl, angakha amabhondi e-hydrogen emanzini ukuze kwandiswe i-viscosity yesisombululo. Ngokulungisa isisindo samangqamuzana kanye ne-substitution degree ye-CMC-Na, i-viscosity yoketshezi lokumba ingalawulwa ukuze kuhlangatshezwane nezidingo zezimo ezihlukahlukene zokumba.
Ukulawula ukuhlunga
Ama-molecule e-CMC-Na angakha uhlaka lwenethiwekhi olunezinhlangothi ezintathu emanzini, olungakha ikhekhe lokuhlunga eliminyene odongeni lomthombo futhi linciphise ukulahleka kokuhlunga koketshezi lokumba. Ukwakhiwa kwekhekhe lokuhlunga akuxhomekile kuphela ekugxilweni kwe-CMC-Na, kodwa futhi nesisindo sayo samangqamuzana kanye ne-substitution degree.
Ukuthambisa
Ama-molecule e-CMC-Na angakhangiswa ebusweni bebhithi yokubhoboza kanye nodonga lomthombo emanzini ukuze akhe ifilimu yokugcoba nokunciphisa i-coefficient yokungqubuzana. Ngaphezu kwalokho, i-CMC-Na futhi inganciphisa ngokungaqondile ukungqubuzana phakathi kwe-drill bit kanye nodonga lomthombo ngokulungisa i-viscosity yoketshezi lokumba.
Ukuzinza okushisayo
I-CMC-Na ingagcina ukuqina kwesakhiwo sayo samangqamuzana ngaphansi kwezimo zokushisa okuphezulu futhi ayijwayele ukuwohloka kokushisa. Lokhu kungenxa yokuthi amaqembu e-carboxyl kuma-molecule ayo angakha amabhondi e-hydrogen azinzile nama-molecule amanzi ukuze amelane nokulimala kwezinga lokushisa eliphezulu. Ngaphezu kwalokho, i-CMC-Na futhi inokumelana okuhle kukasawoti futhi ingagcina ukusebenza kwayo ekubunjweni kukasawoti.
4. Izibonelo Zokusebenza Ze-Sodium Carboxymethyl Cellulose
Enqubweni yangempela yokumba, umphumela wokusetshenziswa kwe-sodium carboxymethyl cellulose uyamangalisa. Isibonelo, kuphrojekthi yokumba umthombo ojulile, isistimu yoketshezi yokumba equkethe i-CMC-Na yasetshenziswa ukuze kulawulwe ngempumelelo ukuqina nokulahlekelwa kokuhlunga komthombo, ukwandisa isivinini sokumba, nokunciphisa izindleko zokumba. Ngaphezu kwalokho, i-CMC-Na nayo isetshenziswa kabanzi ekubholeni olwandle, futhi ukumelana kwayo nosawoti omuhle kuyenza isebenze kahle endaweni yasolwandle.
Ukusetshenziswa kwe-sodium carboxymethyl cellulose oketshezini lokumba ikakhulukazi kuhlanganisa izici ezine: ukuqina, ukwehlisa ukulahlekelwa kwamanzi, ukuthambisa kanye nokuzinza. Izakhiwo zayo eziyingqayizivele zomzimba namakhemikhali ziyenza ibe yingxenye ebalulekile ohlelweni loketshezi lokumba. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokumba, amathuba okusetshenziswa kwe-sodium carboxymethyl cellulose azoba banzi. Ocwaningweni oluzayo, ukwakheka kwamangqamuzana nezindlela zokuguqula ze-CMC-Na zingathuthukiswa ukuze kuthuthukiswe ukusebenza kwayo futhi kuhlangatshezwane nezidingo zezindawo zokumba eziyinkimbinkimbi.
