I-Sodium Carboxymethyl Selelose (CMC-NA emfutshane) yi-polymer elona candelo linyibilikisi lawo kwaye lisetyenziswa kakhulu kwi-onid yeoyile. Iipropathi zayo ezizodwa zenza ukuba ibe yinto engenakuphikwa kwinkqubo yokuqhuba.
I-1. Iipropathi ezisisiseko ze-sodium ye-sodium carboxethyl seluplose
I-Sodium Carboxymethyl Selelose yi-Aneion I-Aursulose Ether eveliswe ngu-SellUlose emva konyango lwe-Alkali kunye ne-chlorocetic acid. Isakhiwo sayo semolekyuli sinenani elikhulu le-carboxymethyl amaqela, eyenza ukuba ibe ne-smorability elungileyo kunye nozinzo. I-CMC-NA inokwenza isisombululo se-viscofity ephezulu emanzini, sinamanzi, ukuzinza kunye nokuzinza kwefilimu.
2. Ukusetyenziswa kwe-sodium yebhokisi ye-sodium ye-sodium
Tickener
I-CMC-NA isetyenziswa njenge-tickener kwi-flollting fluid. Umsebenzi wayo ophambili kukwandisa i-viscofity ye-fescofity fluid kwaye uphucule amandla ayo okuthwalela izitoliki kunye nokuqhutywa kwemida. I-viscofity efanelekileyo yokuqhuba ulwelo inokuthintela ngokufanelekileyo ukuwa udonga oluhle kwaye ugcine uzinzo lweFlebore.
Ilahleko yelahleko
Ngexesha lenkqubo yokuqhuba, ukuntywila kuya kungena kwi-pores yoluvo, kubangela ukuphulukana kwamanzi kwi-fluid fluid, kodwa inokubangela ukubamba i-fludse kunye nemonakalo yokugcina amanzi. Njengomda welahleko yolwelo, i-CMC-NA inokwakha ikhekhe lokucoca i-filserthol doll, ngokufanelekileyo ukunciphisa ilahleko yokufakelwa kwe-flud kunye nokukhusela udonga kunye nodonga lodonga.
Ioyile
Ngexesha lenkqubo yokuqhuba, ukungqubana phakathi kwe-Drll bit kwaye udonga lodonga luya kuvelisa ubushushu obuninzi, lukhokelela ekunikezelweni kwaso kwesixhobo sokunxila. I-Litharity ye-CMC-NA iyanceda ukunciphisa ukuxabana, ukunciphisa ukusetyenziswa kwesixhobo sokunxila, kunye nokuphucula ukusebenza kakuhle.
I-stabilizer
Ukuntywila kuya kubhabha okanye kungcolise ubushushu obuphezulu kunye noxinzelelo oluphezulu, ngaloo ndlela ukuphulukana nomsebenzi wayo. I-CMC-NA inesizinzo esihle sokungazinzi kunye nokungaxhathisi ityuwa, kwaye sinokugcina uzinzo lokuntywila phantsi kweemeko ezinzima kwaye kwandise ubomi benkonzo.
I-3. Indlela yokusebenza ye-Sodium Carboxymethyl Selelose
Ulungelelwaniso lwe-viscosity
Isakhiwo se-molecular se-CMC-NA iqulethe inani elikhulu le-carboxymethyl, enokwenza imibhobho ye-hydrogen emanzini yokwandisa i-viscofity yesisombululo. Ngokuhlengahlengisa ubunzima bemoyam kunye nenqanaba lokufaka endaweni ye-CMC-NA, i-viscosity ye-fluid i-sfaid ingalawulwa ukuba ifezekiswe iimfuno zemeko ezahlukeneyo zokumba.
Ulawulo oluqhelekileyo
I-CMC-NA Molekles inokwenza ubume benethiwekhi ezintathu emanzini, enokwenza ikhekhe lokucoca i-filser equleni kwaye lunciphise ukuphulukana nokulahleka kwe-terlling fluid. Ukwenziwa kwekhekhe yefilitha kuxhomekeke kuphela kwi-CMC-na, kodwa kunye nobunzima bemolekyuli kunye nenqanaba lokufaka endaweni.
I-Lubrication
I-CMC-NA Molecules inokubekwa kumphezulu we-Drill bit kunye nodonga lomlilo emanzini ukwenza ifilimu etyhafisayo kwaye inciphise i-factions eyoneleyo. Ukongeza, i-CMC-NA inokungathanga ngokungathanga ngqo ukunciphisa ukungqubana phakathi kwe-Drill Tim kunye nodonga lodonga ngokuhlengahlengisa i-viscofity fluid.
Uzinzo lwe-thermal
I-CMC-NA inokugcina uzinzo lwesakhiwo sayo semolekyuli phantsi kweemeko zobushushu obuphezulu kwaye ayihambelani ekuthambekeni kwe-thermal. Kungenxa yokuba amaqela e-carboxyl kwiimolekyuli zawo angenza amaqhina ozinzileyo eemolekyuli zamanzi ukuze axhathise umonakalo wobushushu obuphezulu. Ukongeza, i-CMC-na ikwachasa ngenzondelelo yetyuwa kwaye inokugcina intsebenzo yayo kwiiliti.
4. Imizekelo yesicelo ye-sodium ye-sodium ye-sodium ye-sodium
Kwinkqubo yokuqhuba i-octlling, isiphumo sesicelo se-Sodium Carboxymethyl Selelose iphawuleka. Umzekelo, kwiprojekthi yokuqhuba kakuhle, inkqubo yokuqhuba equlathe i-CMC-NA yayisetyenziselwa ukulawula ngokufanelekileyo iziqulatho zozinzo kunye nequla le-quelbore, yandisa isantya sokumba, kwaye sinciphise iindleko zokumba. Ukongeza, i-CMC-NA isetyenziswa ngokubanzi kwi-Marine Dring, kwaye ukunganyangeki kwetyuwa yayo kwenza ukuba kwenze kakuhle kwindawo yaselwandle.
Ukusetyenziswa kwe-Sodium Carboxymethyl Selelose kwi-Sleid iquka ikakhulu iquka iinkalo ezine: ukuthambisa, ukunciphisa ukulahleka kwamanzi, ukwehla kunye nokuzinza. Ipropathi yayo eyahlukileyo yomzimba kunye neekhemikhali zenza ukuba ibe yinto engenakuphikwa kwinkqubo yokuqhuba. Ngokuphuhliswa okuqhubekayo kwetekhnoloji yokumba, ithemba lesicelo le-sodium ye-sodiumdymethyl iya kuba sandisi. Kwixesha elizayo, indlela yemolekyuli kunye neendlela zokulungiswa kwe-CMC-NA zinokufezekiswa ukuqhubela phambili ukusebenza kwalo kwaye zifezekise iimfuno zendawo ezinzima zokugrovuza.
