Amathiphu obuchwepheshe okuvimbela ukugqwala kwezando

Izando zingelinye lamathuluzi asetshenziswa kakhulu kuzo zonke izimboni nemizi eyahlukene. Naphezu kokuklama kwabo okulula, babhekene nemisebenzi enzima, okwenza kube lula ukuguga. Enye yezinkinga ezibalulekile ezibhekene nezando, ikakhulukazi lezo ezenziwe ngensimbi, ukugqwala. Ukugqwala akugcini nje ngokunciphisa ukukhanga kobuhle besando kodwa futhi kunciphisa ukuqina nokusebenza kwayo. Ukuze kuliwe nalokhu, abakhiqizi basebenzisa amasu anhlobonhlobo e-anti-corrosion ukuze balule isikhathi sokuphila kwezando. Lesi sihloko sihlola ezinye zezindlela eziphumelela kakhulu zokulwa nokugqwala ezisetshenziswa kuukukhiqiza isando.

1.Ukukhetha Okubalulekile

Ukulwa nokugqwala kuqala esigabeni sokukhetha impahla. Izando eziningi zenziwe ngensimbi enekhabhoni ephezulu, eqinile kodwa ejwayele ukugqwala. Ukunciphisa lokhu, abakhiqizi bavame ukukhetha izinsimbi ze-alloy eziqukethe izinto ezifana ne-chromium, i-nickel, ne-molybdenum. Lezi zinto zithuthukisa ukumelana kwensimbi ekugqwaleni. Insimbi engagqwali, ngokwesibonelo, iyinketho ethandwayo ngenxa yezindawo zayo ezinhle kakhulu zokulwa nokugqwala, nakuba zibiza kakhulu kunensimbi ye-carbon evamile.

2.Izingubo Zokuzivikela

Enye yezindlela ezivame kakhulu futhi eziphumelelayo zokuvimbela ukugqwala ukusebenzisa isambatho esivikelayo esando. Kunezinhlobo eziningana zama-coatings angasetshenziswa:

• I-Zinc Plating: Lokhu kuhilela ukumboza isando ngongqimba oluncane lwezinc, olusebenza njengesendlalelo somhlatshelo esigqwala esikhundleni sensimbi engaphansi. Izando ezifakwe ku-Zinc zimelana kakhulu nokugqwala futhi zivame ukusetshenziswa ezindaweni lapho ithuluzi lichayeka khona kumswakama.
• I-Powder Coating: Ukugcoba nge-powder kuyinkqubo eyomile yokuqeda lapho impushana (ngokuvamile i-thermoplastic noma i-thermoset polymer) isetshenziswa ebusweni besando bese yelashwa ngaphansi kokushisa. Lokhu kudala isiphetho esiqinile, esiqinile esimelana nokugqwala nokuguga.
• I-galvanization: Le nqubo ihilela ukucwilisa isando ku-zinc encibilikisiwe ukuze kwakhe ungqimba oluwugqinsi oluvikelayo. Izando eziphehliwe zisebenza kahle kakhulu ekulweni nokugqwala futhi zilungele ukusetshenziswa ngaphandle noma ezimbonini.

3.Ukwelashwa Kwamafutha Nengcina

Ngezando ezidinga ukugcina ukubukeka kwendabuko kakhudlwana, ikakhulukazi lezo ezinezibambo zokhuni, ukwelashwa kwamafutha kanye ne-wax kuvame ukusetshenziswa. Lezi zinto zingena endaweni yensimbi futhi zenze umgoqo oxosha umswakama futhi zinciphise ingozi yokugqwala. Amafutha e-linseed, ingcina yezinyosi, namafutha e-tung avame ukusetshenziswa kulezi zindlela zokwelapha. Nakuba kungenakuqina njengama-coatings, lokhu kwelashwa kulula ukukusebenzisa futhi kungasetshenziswa kabusha ngezikhathi ezithile ukuze kugcinwe ukuvikeleka.

4.Ukwelashwa Kokushisa

Izinqubo zokwelapha ukushisa, njengokucisha nokushisa, akuzona nje zokuthuthukisa amandla nokuqina kwesando; zingabamba iqhaza futhi ekuthuthukiseni ukumelana nokugqwala. Ngokushintsha i-microstructure yensimbi, ukwelashwa kokushisa kunganciphisa ukuthambekela kwensimbi ukugqwala. Kodwa-ke, le nqubo ivame ukuhlanganiswa nezinye izindlela, njengokumboza noma ukukhetha izinto ezibonakalayo, ukuze kube nemiphumela emihle.

5.Stainless Steel Construction

Kuzinhlelo zokusebenza lapho ukumelana nokugqwala kubaluleke kakhulu, izando zensimbi engagqwali ziyisinqumo esihle kakhulu. Insimbi engagqwali iqukethe iphesenti eliphezulu le-chromium, eyakha ungqimba lwe-passive ebusweni bensimbi, evimbela ukugqwala ukuthi kungakheki. Nakuba zibiza kakhulu, izando zensimbi engagqwali zidinga ukulungiswa okuncane futhi zilungele izindawo ezinomswakama ophezulu noma ukuchayeka ezintweni ezigqwalayo.

6.Isondlo Esivamile

Ngaphandle kwamasu okukhiqiza, ukugcinwa okuvamile kudlala indima ebalulekile ekuvimbeleni ukugqwala kwesando. Izenzo ezilula, ezinjengokwesula isando ngemva kokusetshenziswa, ukusigcina endaweni eyomile, nokusebenzisa uwoyela okhanyayo ngezikhathi ezithile, kungalula kakhulu ukuphila kwethuluzi. Abasebenzisi kufanele futhi bahlole noma yiziphi izimpawu zokugqwala noma ukuguga futhi babhekane nazo ngokushesha ukuvimbela ukulimala okwengeziwe.

Isiphetho

Ukugqwala kuyinselelo ebalulekile ekugcineni ubude besikhathi nokusebenza kwezando, kodwa ngamasu afanele, kungaphathwa ngempumelelo. Kusukela ekukhethweni kwezinto ezibonakalayo kanye nezingubo zokuzivikela kuya ekunakekeleni okuvamile, kunamasu amaningi abakhiqizi nabasebenzisi abangawasebenzisa ukuze bavikele izando ekugqwaleni nasekugqwaleni. Ngokutshala imali kulezi zindlela zokulwa nokugqwala, ungaqinisekisa ukuthi isando sakho sihlala siyithuluzi elithembekile neliqinile iminyaka eminingi ezayo.
