▲Ukuxuba ne-imidazoline nezinye izingxenye ze-synergistic kungavimbela izinsimbi (i-carbon steel) ekugqwaleni ezinhlelweni zamanzi zokukhiqiza i-oilfield ene-H2S ephezulu, i-CO2, amanzi anosawoti amaningi anosawoti omningi, kanye ne-Cl-ngesikhathi sokubuyiswa kwamafutha.
Izinzuzo
> Vimbela ukugqwala kwe-carbon steel nge-H₂S ephezulu, i-CO₂, amanzi anosawoti omningi anosawoti kanye ne-Cl⁻.
>Isetshenziselwa ikakhulukazi ukuqoqa uwoyela negesi kanye nokuthuthwa kanye nokwelashwa kwamanzi okuhluza uwoyela, ikakhulukazi ohlelweni lwamanzi lokukhiqiza insimu kawoyela.
>Inomphumela wokuvikela ezigabeni ezintathu zikawoyela, igesi namanzi, futhi inokuhambisana okuhle namanye amakhemikhali.
Ukuphatha Okunconyiwe
▶ Bonke abasebenzi abaphethe le nto kumele bayiphathe njengekhemikhali yasezimbonini, bagqoke izinto ezivikelayo futhi babheke izinyathelo zokuphepha njengoba kuchazwe ku-Material Safety Data Sheet (MSDS).
Ukupakisha kanye Nesitoreji
Ipakishwe ku-200 litre wensimbi noma izigubhu zepulasitiki.
Gcina endaweni eyomile, enomoya omuhle. Gcina isiqukathi sivaliwe. Gwema ukushisa, izinhlansi namalangabi. Gcina kude nezinto ezingahambisani. Landela izinqubo eziphephile zokulondoloza impahla mayelana nokupakisha, ukuhlanganisa, ukugoqa kanye/noma ukupakisha

1. Ifilimu Ye-Adsorption (I-Adsorption Film Type Corrosion Inhibitor)
- I-Film Formation Mechanism:
Ama-adsorption film type corrosion inhibitors akha ifilimu evikelayo endaweni yensimbi ngokusebenzisai-adsorption. I-Adsorption ingaba yizinhlobo ezimbili:- I-Adsorption Engokwenyama: Ithembele ekusebenzelaneni okubuthakathaka okufana nokuphoqa kuka-van der Waals phakathi kwama-molecule ukunamathela endaweni yensimbi.
- I-Chemical Adsorption: Yakha isendlalelo se-adsorption esinamandla ngokusebenzisa isibopho samakhemikhali phakathi kwama-molecule nendawo yensimbi.
Ukwakhiwa kwale filimu kuncike ekutheniubuhloboyama-molecule e-inhibitor endaweni yensimbi futhi ayidingi ukusabela kwamakhemikhali okuyinkimbinkimbi.
- Izimpawu Zefilimu:
- Ubukhulu: Ifilimu incane kakhulu, imvamisa ai-monolayer noma i-multilayer.
- Isakhiwo: Ifilimu ilula uma kuqhathaniswa, ngokuyinhloko isebenza njengesithiyo sokuvimbela imidiya ebolayo (njengamanzi, umoya-mpilo, ama-ion) ukuthi ingathintani nensimbi.
- Izici:
- Inikeza ukumbozwa okufanayo endaweni yensimbi futhi inezinhlobonhlobo zezinhlelo zokusebenza.
- Ifanele izindawo ezivamile zokubola kodwa ingase ingazinzi ngokwanele ngaphansi kwezimo ezimbi kakhulu njengezinga lokushisa eliphezulu nokucindezela okuphezulu.
2. Ukwenza Amafilimu (Isivimbeli Se-Amine Esakha Ifilimu)
- I-Film Formation Mechanism:
Ama-film-forming amine type corrosion inhibitors akha ifilimu eliqinile elivikelayo endaweni yensimbi ngokusebenzisaukusabela kwamakhemikhalinomaukufakwa ngokomzimba.- Ukusabela Kwamakhemikhali: Amangqamuzana e-amine asabela nengaphezulu lensimbi ukuze akhe izinhlanganisela ezingancibiliki noma izinkimbinkimbi.
- I-Physical Deposition: Ama-amine ama-molecule abeka futhi anqwabelane endaweni yensimbi ukuze akhe ifilimu ewugqinsi.
Inqubo yokwakhiwa kwefilimu ngokuvamile ihilela ukusebenzisana kwamangqamuzana okuyinkimbinkimbi, okuholela efilimini ezinzile.
- Izimpawu Zefilimu:
- Ubukhulu: Ifilimu iwugqinsi uma kuqhathaniswa, ngokuvamile iyafinyelelaamashumi kuya kumakhulu ama-nanometer.
- Isakhiwo: Ifilimu iminyene futhi iqinile, ihlukanisa ngokuphumelelayo imidiya egqwalayo, ikakhulukazi elungele izindawo ezinokhahlo.
- Izici:
- Inenhle kakhuluukumelana nezinga lokushisa eliphezulufuthiukumelana nokugqwala.
- Ifanele izinga lokushisa eliphezulu, ingcindezi ephezulu, kanye nezindawo ezonakalisa kakhulu.
3. Umehluko Oyinhloko Phakathi Kwe-"Adsorption Film" kanye "Ne-Film-Forming"
Isici | Ifilimu ye-Adsorption (I-Adsorption Film Type Corrosion Inhibitor) | Ukwenza Ifilimu (I-Amine-Forming Amine Type Corrosion Inhibitor) |
|---|---|---|
I-Film Formation Mechanism | Uthembele ku i-adsorption (i-adsorption ebonakalayo noma yamakhemikhali) | Uthembele ku ukusabela kwamakhemikhali noma ukufakwa ngokomzimba |
Ukujiya Kwefilimu | Izacile (i-monolayer noma i-multilayer) | Ukuqina (amashumi kuya kumakhulu ama-nanometers) |
Inqubo Yokwakheka | Kulula, kuncike ekuhlobaneni kwamangqamuzana | Okuyinkimbinkimbi, kungase kuhlanganise ukusabela kwamakhemikhali noma izinqubo zokubeka |
Umphumela Wokuvikela | Ivimba imidiya eyonakalisayo, ilungele izindawo ezijwayelekile | Ihlukanisa ngokuqinile imidiya ebolayo, efanele izindawo eziyingozi kakhulu |
- Ukwakheka kwe-ifilimu ye-adsorptionithembele kakhulu ekungeneni kwama-molecule e-inhibitor endaweni yensimbi, okuholela efilimini elincanyana nelikhanyayo elifanele ukuvikela izinsimbi ezindaweni ezigqwalile ezimaphakathi.
- Ukwenza ifilimungakolunye uhlangothi, yakha ungqimba oluyisivikelo olujiyile ngokusebenzisa ukusabela kwamakhemikhali noma ukufakwa, olumelana nezinga lokushisa eliphezulu nokugqwala, okulwenza lufaneleke izimo ezinzima kakhulu.
