E-China Intengo eshibhile i-Hydroxypropyl Methyl Cellulose Ether Yezinsimbi Ezisekelwe Kusimende Ezisekelwe Kumathayela - I-Polyanionic cellulose (PAC) – Yeyuan

I-Polyanionic cellulose (PAC) iphuma ngokuphuma emanzini i-cellulose ether encibilika elungiswe ukuguqulwa kwamakhemikhali kwe-cellulose yemvelo. Kuyi-ether ye-cellulose encibilikayo ebalulekile emanzini. Ivamise ukusetshenziswa njengosawoti wayo we-sodium futhi isetshenziswa kakhulu ekumbeni uwoyela, ikakhulukazi imithombo yamanzi anosawoti kanye nokumba uwoyela ogwini lolwandle.

PAC-Application In Petroleum

1. Imisebenzi ye-PAC ne-CMC emkhakheni kawoyela imi kanje:
- Udaka oluqukethe i-PAC ne-CMC lungenza udonga lomthombo lube mncane futhi luqine ikhekhe lokuhlunga elikwazi ukungena kancane futhi lunciphise ukulahleka kwamanzi;
- Ngemva kokwengeza i-PAC ne-CMC odakeni, umshini wokumba ungathola amandla okugunda okuqala aphansi, wenze udaka lube lula ukukhulula igesi egoqwe kulo, futhi ulahle ngokushesha imfucumfucu emgodini wodaka;
- Njengezinye izinto ezisatshalaliswa ezimisiwe, udaka lokumba lunesikhathi esithile sokuba khona, esingaqiniswa futhi sinwetshwe ngokwengeza i-PAC ne-CMC.
2. I-PAC ne-CMC zinokusebenza okuhle kakhulu okulandelayo ekusetshenzisweni kwendawo kawoyela:
- Izinga eliphezulu lokushintsha, ukufana okuhle kokushintshanisa, i-viscosity ephezulu kanye nomthamo ophansi, ukuthuthukisa ngempumelelo ukusebenza kodaka;
- Ukumelana nomswakama omuhle, ukumelana nosawoti kanye nokumelana ne-alkali, kulungele amanzi ahlanzekile, amanzi olwandle kanye nodaka olusekelwe emanzini olune-brine;
- Ikhekhe lodaka elakhiwe lisezingeni elihle futhi lizinzile, elingakwazi ukusimamisa kahle isakhiwo senhlabathi ethambile futhi livimbele ukuwa kodonga lwe-shaft;
- Ilungele izinhlelo zodaka ezinokulawulwa kokuqukethwe okuqinile okunzima kanye nobubanzi obuhlukahlukene.
3. Izici zokusetshenziswa kwe-PAC kanye ne-CMC ekumba uwoyela:
- Inamandla aphezulu okulawula ukulahleka kwamanzi, ikakhulukazi isinciphisi esisebenzayo sokulahlekelwa uketshezi. Ngomthamo ophansi, ungalawula ukulahlekelwa kwamanzi ezingeni eliphezulu ngaphandle kokuthinta ezinye izakhiwo zodaka;
- Inokumelana kahle nezinga lokushisa kanye nokumelana nosawoti okuhle kakhulu. Ingase ibe nekhono elihle lokunciphisa ukulahlekelwa kwamanzi kanye ne-rheology ethile ngaphansi kokuhlushwa kukasawoti othile. I-viscosity cishe ayishintshile ngemva kokuncibilika emanzini anosawoti. Ifaneleka ngokukhethekile ukumba ogwini kanye nemithombo ejulile;
- Ingakwazi ukulawula kahle i-rheology yodaka futhi ine-thixotropy enhle. Ilungele noma yiluphi udaka olusekelwe emanzini emanzini ahlanzekile, emanzini olwandle kanye ne-saturated brine;
- Ngaphezu kwalokho, i-PAC isetshenziswa njengoketshezi lukasimende ukuvimbela uketshezi ukuthi lungangeni ezimbotsheni nasekuqhekekeni;
- Uketshezi lomshini wokuhlunga olungiselelwe nge-PAC unokumelana okuhle nesisombululo esingu-2% se-KCl (kufanele sengezwe lapho ulungiselela uketshezi lomshini wokuhlunga), ukuncibilika okuhle, ukusetshenziswa okulula, kungalungiselelwa esizeni, ijeli elisheshayo lokwakha isivinini kanye nomthamo oqinile wokuthwala isihlabathi. Uma isetshenziswa ekwakhekeni kokungeneka okuphansi, umphumela wayo wokucindezela isihlungi muhle kakhulu.
