Umqhele t40. Ingabe ukwakheka okuhlukile kuyasebenza?
Izinzuzo
I-ejenti elwa nokugqwala kwe-Krown t40 ibekwe njengesiguquli sokugqwala esinohlaka olubanzi lwesenzo namandla ahlabayo aphezulu. Njengeminye imikhiqizo efanayo (isibonelo, i-Tectyl), ingena ngokujulile kuwo wonke amalunga namavolumu lapho amabala okugqwala avela khona, asebenza isikhathi eside, avikela zonke izakhi zesakhiwo sensimbi ephathwayo.
Ingasetshenziselwa ukuvimbela izindawo zokugqwala ezinsimbi ezingenayo ayoni nezinsimbi, izingxenye ezenziwe ngepulasitiki noma irabha, ivikela ekugugulekeni. Idlula kahle kuzo zonke izindawo okunzima ukufinyelela kuzo, isusa umswakama lapho, omisa izinqubo zokugqwala.
Izinzuzo ze-Crown t40 nazo ziyi:
- Ithuba lokusebenzisa hhayi kuphela ezimotweni ezinamasondo, kodwa futhi ekuphileni kwansuku zonke, ukucubungula ngezikhathi ezithile izingidi zeminyango, izivalo zamafasitela, noma yiziphi izingxenye ezisebenza ngaphansi kwezimo zokungqubuzana okukhulu.
- Inzuzo, ukungabi nobuthi kanye nokuphepha kwemvelo, ngoba umkhiqizo awunawo ama-solvents nezithasiselo eziyingozi.
- Ukungabi khona kwezidingo ezikhulayo zokucophelela kokusebenzisa umuthi ebusweni.
- Ukusebenziseka kalula kokucubungula kanye nobude bomphumela ozuziwe we-anticorrosive.
Izakhiwo ezihlukile zokugcoba ze-Crown t40 ziphinde ziqinisekise ukuvikeleka ekugqwaleni, okubangelwa amaza anhlanhlathayo kanye nokunqanyulwa okungapheli kwezinto zokuxhumana zamandla kagesi. Ngaphezu kwalokho, umuthi:
- Inikeza isivikelo ekunamatheleni nasekukhiyeni izingidi zeminyango namalashi.
- Ivimbela i-acidification yezinsimbi.
- Iqeda ukukhiya amahinge nezinye izindlela ezihambayo.
Inqubo yesenzo
Njengoba wazi, izingxenye zemoto ezifana nama-welds akhiwe ubuchwepheshe be-welding, ama-sills, ama-wheel blocks, i-bottom yemoto kanye nezinye eziningi zibhekene nokugqwala okukhulu kakhulu. Ngakho-ke, i-agent anti-corrosion kumele ikwazi ukungena kuzo zonke izindawo ezingenhla, inikeze ukuvikelwa okuthembekile.
Ukususwa kokugqwala kwezobuchwepheshe kusetshenziswa i-Krown T40 akudingi ukulungiswa kwendawo yokuqala kanye nokomiswa kwayo okulandelayo. Izingxenye zeCrown Anti-Corrosion Treatment zingamafutha acwengisiswe kakhulu aqukethe uhla lwezithako. Ngenxa yalokho, ukuqina okwenyuka kokungena kunikezwa, kulandelwa ukukhishwa komswakama ovela ezikhaleni ezikhona. Indawo ephathwayo ithola izakhiwo ezidingekayo zokuzivikela, kuhlanganise nokuvimbela ukugqwala. Ngenxa yesilinganiso esikhethwe kahle sazo zonke izakhi, zonke izindawo ezivikelekile azihlali esimweni sokungenzi lutho, futhi ifilimu engaphezulu imelana kakhulu yakha umgoqo wokuvikela othembekile, futhi iba umqhubi osebenzayo wama-molecule ezidakamizwa.
Ngesikhathi sokusebenza kwemoto, izinto ezakha i-anticorrosive agent ye-Krown T40 zihlala zihamba endaweni yokuxhumana, lapho ziqeda khona izikhungo zokugqwala ezingase zibe khona. Lapho usebenzisana, izingxenye zomuthi zibonisa ukuminyana okuphezulu, ngenxa yokuthi zigcwalisa izindawo eziphathwayo ngama-molecule azo, bese zisebenzisa i-chemisorption (ukumuncwa kwezidakamizwa) phezu kwayo yonke indawo yensimbi; Lokhu okungenhla kwenza kube nokwenzeka ukuqeda ububi obuhambisana nezindlela eziningi ezijwayelekile zokuvikela ukugqwala.
Indlela yokusebenza kwethuluzi imi kanje. Okokuqala, ama-molecule e-corrosion inhibitors kanye nama-repellants amanzi angeniswa phezulu. Ezinye zazo ziyamuncwa futhi zimuncwe, kanti ezinye zikhama amanzi nezixazululo zikasawoti we-electrolyte ohlukahlukene, onomthelela omkhulu ekugqwaleni. Ngemva kokwakhiwa kwe-monomolecular layer ye-inhibitor (isigaba sesibili), ithuthela endaweni yokugqwala evelayo, lapho ilungiswa khona amandla okunamathela kwamangqamuzana.
Ukwelashwa kwe-Crown anti-corrosion: ukubuyekezwa
Abasebenzisi baqaphela ukusebenziseka kalula kokucubungula ngenxa yokuthi umkhiqizo ungasetshenziswa phezulu ngaphandle kokuwuhlanza kahle othulini nokungcola. Lawo ma-anticorrosive agents akha ifilimu engaphezulu adinga ukulawula okukhethekile ezindaweni eziphathwayo ukuze kubonakale ukuxebuka kwefilimu kanye nezindawo zokuqala zokugqwala ngesikhathi. Ngesikhathi esifanayo, izingxenye ze-Krown T40 azikhuni, kodwa zihlala zisesimweni esisebenzayo, ngaleyo ndlela zigcwalisa zonke iziqephu ezenzeka ngokuhamba kwesikhathi ezintweni. Abaningi baqaphela ukuxhumana okuqinile komuthi ngensimbi ephathwayo, eyenziwa ku-nanolevel. Kuboniswa ukuthi ama-corrosion inhibitors awagcini nje ukunciphisa ukuqhubeka kwengqimba ekhululiwe yokugqwala, kodwa futhi ayisuse phezulu. Lapho, ukugqwala kudluliswa, i-oxidation eyengeziwe yensimbi iyama, futhi isisindo esixekethile silahlekelwa ukubamba kwayo futhi sivele siwele phezulu ngaphansi kwethonya lokushaqeka okunamandla komzimba wemoto.
Njengoba kuqinisekisiwe ekusebenzeni, ukuphumelela kwesenzo se-anticorrosive ebhekwayo akuhlali ngaphezu kwezinyanga ezingu-24 ... 36 (kuye ngokuthi ukuqina kokusetshenziswa kwemoto). Ngemva kwalokho, ukucubungula kufanele kuphindwe.
Izibuyekezo eziningi zibika ukuphepha komlilo kokubunjwa, kanye nokungabikho komthelela omubi emvelweni. Kuyaphawulwa ukuthi i-Krown T40 inezindawo ze-dielectric futhi ikwazi ukumelana nama-voltage e-AC afika ku-50 kV.
