Carboxymethyl cellulose (CMC) ndi polima wosungunuka m'madzi wopangidwa kuchokera ku cellulose, womwe umagwiritsidwa ntchito m'mafakitale osiyanasiyana chifukwa chakukhuthala, kukhazikika, komanso kukulitsa. High viscosity CMC (CMC-HV) makamaka ili ndi mikhalidwe yapadera yomwe imapangitsa kuti ikhale yamtengo wapatali pamapulogalamu okhudzana ndi mafuta.
1. Mapangidwe a Chemical ndi Mapangidwe
CMC imapangidwa ndi kusintha kwa mankhwala a cellulose, polima wachilengedwe wopezeka m'makoma a cellulose. Njirayi imaphatikizapo kuyambitsa magulu a carboxymethyl (-CH2-COOH) mu cellulose msana, zomwe zimapangitsa cellulose kusungunuka m'madzi. Digiri ya m'malo (DS), yomwe imatanthawuza kuchuluka kwamagulu a carboxymethyl pagawo la anhydroglucose mu molekyulu ya cellulose, imakhudza kwambiri CMC. Kukhuthala kwa mafuta a Petroleum CMC nthawi zambiri kumakhala ndi DS yayikulu, kumapangitsa kusungunuka kwamadzi komanso kukhuthala kwake.
2. Kukhuthala kwakukulu
Makhalidwe a CMC-HV ndi kukhuthala kwake kwakukulu akasungunuka m'madzi. Viscosity ndi muyeso wa kukana kwamadzimadzi kuti asayende, ndipo kukhuthala kwamphamvu kwa CMC kumapanga njira yokhuthala, yonga gel ngakhale pamiyeso yotsika. Katunduyu ndi wofunikira pakugwiritsa ntchito mafuta amafuta komwe CMC-HV imagwiritsidwa ntchito posintha mawonekedwe amadzi akubowola ndi zina. Kukhuthala kwakukulu kumatsimikizira kuyimitsidwa kogwira mtima kwa zolimba, mafuta abwinoko, komanso kukhazikika kwamatope obowola bwino.
3. Kusungunuka kwamadzi
CMC-HV imasungunuka kwambiri m'madzi, yomwe ndi yofunika kwambiri kuti igwiritsidwe ntchito pamakampani amafuta. Akawonjezeredwa kumadzi opangira madzi, amatsitsimutsa mofulumira ndikusungunuka, kupanga njira yofanana. Kusungunuka kumeneku ndikofunikira pakukonzekera bwino ndikugwiritsa ntchito madzi obowola, ma slurries a simenti, ndi madzi omaliza mu ntchito ya petroleum.
4. Kukhazikika kwa kutentha
Ntchito zamafuta nthawi zambiri zimakhala ndi malo otentha kwambiri, ndipo kukhazikika kwamafuta a CMC-HV ndikofunikira. Gulu ili la CMC lapangidwa kuti lizisunga mamasukidwe ake ndi magwiridwe antchito pansi pa kutentha kokwera, nthawi zambiri mpaka 150 ° C (302 ° F). Kukhazikika kwamafutawa kumatsimikizira kugwira ntchito kosasinthasintha pakubowola ndi kupanga, kuteteza kuwonongeka ndi kutayika kwa katundu.
5. pH Kukhazikika
CMC-HV imawonetsa kukhazikika kwa pH yamitundu yosiyanasiyana, nthawi zambiri kuyambira 4 mpaka 11. Kukhazikika kwa pH kumeneku ndikofunikira chifukwa madzi obowola ndi mafuta ena okhudzana ndi mafuta amatha kukumana ndi pH yosiyana. Kusunga mamasukidwe akayendedwe ndi magwiridwe antchito m'malo osiyanasiyana a pH kumatsimikizira kugwira ntchito ndi kudalirika kwa CMC-HV m'malo osiyanasiyana ogwirira ntchito.
6. Kulekerera Mchere
Pa mafuta odzola, madzi nthawi zambiri amakumana ndi mchere wambiri komanso ma electrolyte. CMC-HV imapangidwa kuti ikhale yololera madera oterowo, kusunga mamasukidwe ake komanso magwiridwe antchito pamaso pa mchere. Kulekerera kwa mchere kumeneku kumakhala kopindulitsa makamaka pakubowola m'mphepete mwa nyanja ndi ntchito zina pomwe mikhalidwe yamchere imakhala yofala.
7. Kuwongolera Kusefera
Imodzi mwa ntchito zofunika kwambiri za CMC-HV pakubowola madzi ndikuwongolera kutaya kwamadzimadzi, komwe kumadziwikanso kuti kusefera. Ikagwiritsidwa ntchito pobowola matope, CMC-HV imathandizira kupanga keke yopyapyala, yosasunthika pamakoma a borehole, kuteteza kutaya kwamadzi ochulukirapo pakupanga. Kuwongolera kusefera kumeneku ndikofunikira kuti chitsime chikhale chokhazikika komanso kupewa kuwonongeka kwa mapangidwe.
8. Biodegradability ndi Environmental Impact
Monga chisankho chosamala zachilengedwe, CMC-HV imatha kuwonongeka ndipo imachokera kuzinthu zongowonjezedwanso. Kuwonongeka kwake kumatanthauza kuti imawonongeka mwachilengedwe pakapita nthawi, kuchepetsa kuwonongeka kwa chilengedwe poyerekeza ndi ma polima opangidwa. Khalidweli ndilofunika kwambiri chifukwa makampani a petroleum amayang'ana kwambiri kukhazikika komanso kuchepetsa zochitika zachilengedwe.
9. Kugwirizana ndi Zowonjezera Zina
CMC-HV nthawi zambiri amagwiritsidwa ntchito limodzi ndi zina zowonjezera pobowola madzi ndi zina mafuta formulations. Kugwirizana kwake ndi mankhwala osiyanasiyana, monga xanthan chingamu, guar chingamu, ndi ma polima opangira, amalola kusinthika kwazinthu zamadzimadzi kuti zikwaniritse zosowa zenizeni. Kusinthasintha kumeneku kumawonjezera magwiridwe antchito komanso mphamvu yamadzi akubowola.
10. Mafuta
Pobowola, kuchepetsa mikangano pakati pa chingwe chobowola ndi pobowo ndikofunikira kuti pobowola bwino komanso kuchepetsa kuvala. CMC-HV imathandizira kukhathamiritsa kwamadzi obowola, kuchepetsa torque ndi kukoka, ndikuwongolera magwiridwe antchito akubowola. Mafutawa amathandizanso kukulitsa moyo wa zida zobowola.
11. Kuyimitsidwa ndi Kukhazikika
Kutha kuyimitsa ndi kukhazikika zolimba m'madzi obowola ndikofunikira kuti tipewe kukhazikika ndikuwonetsetsa kuti zinthu zili ndi zofanana mumadzi onse. CMC-HV amapereka luso kuyimitsidwa kwambiri, kusunga zinthu zolemetsa, cuttings, ndi zolimba zina wogawana anagawira. Kukhazikika kumeneku ndikofunikira kuti pakhale kusasinthika kwamadzimadzi akubowola ndikupewa zovuta zogwirira ntchito.
12. Kugwiritsa Ntchito-Zopindulitsa Zapadera
Madzi Akubowola: Pobowola, CMC-HV imawonjezera kukhuthala, imawongolera kutayika kwamadzimadzi, kukhazikika pobowola, komanso kupereka mafuta. Makhalidwe ake amaonetsetsa kuti ntchito yobowola ikugwira ntchito bwino, imachepetsa kuwononga chilengedwe, ndikuwongolera magwiridwe antchito onse amadzimadzi obowola.
Madzi Omaliza: Madzi akamaliza, CMC-HV imagwiritsidwa ntchito kuwongolera kutaya kwamadzimadzi, kukhazikika kwa chitsime, ndikuwonetsetsa kukhulupirika kwa njira yomaliza. Kukhazikika kwake kwamafuta ndi kuyanjana ndi zowonjezera zina zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pazitsime zotentha kwambiri, zothamanga kwambiri.
Ntchito Zoyimitsa Simenti: M'matope a simenti, CMC-HV imagwira ntchito ngati viscosifier komanso wowongolera kutaya kwamadzi. Zimathandiza kukwaniritsa zomwe zimafunidwa za rheological slurry ya simenti, kuonetsetsa kuyika koyenera ndi kuyika kwa simenti, ndikupewa kusamuka kwa gasi ndi kutaya madzimadzi.
Petroleum grade high viscosity CMC (CMC-HV) ndi polima wosunthika komanso wofunikira pamakampani amafuta. Makhalidwe ake apadera, kuphatikiza kukhuthala kwakukulu, kusungunuka kwamadzi, kukhazikika kwamafuta ndi pH, kulolerana kwa mchere, kuwongolera kusefera, kuwonongeka kwa biodegradability, komanso kugwirizana ndi zina zowonjezera, zimapangitsa kuti zikhale zofunikira kwambiri pazogwiritsa ntchito zosiyanasiyana zokhudzana ndi mafuta. Kuchokera pamadzi obowola mpaka kumaliza ndi kuyika simenti, CMC-HV imathandizira magwiridwe antchito, magwiridwe antchito, komanso kusakhazikika kwachilengedwe pakuchotsa mafuta ndi kupanga. Pamene makampaniwa akupitilirabe kusinthika, kufunikira kwazinthu zogwira ntchito kwambiri, zokometsera zachilengedwe monga CMC-HV zingowonjezereka, ndikugogomezera gawo lofunikira pantchito zamakono zamafuta amafuta.
