Uma amabhizinisi, amapaki, imiphakathi yokuhlala kanye nezindawo zokuthenga zikhetha ithini likadoti langaphandle, ukukhathazeka okukhulu kuhlala kungumonakalo wokugqwala. Imvula, umswakama, iqhwa, imvula ene-asidi kanye nokuguguleka koketshezi lukadoti kwansuku zonke kuzogqwala ngokushesha ithini likadoti lensimbi elivamile, okuholela ekuqhekekeni kopende, imigodi yokugqwala kanye nokuphila isikhathi esifushane kwenkonzo. Ithini lethu likadoti lensimbi elihlungwe kabili eliboniswe esithombeni lisebenzisa ubuchwepheshe bobuchwepheshe bokulwa nokugqwala obunezingqimba eziningi, lixazulula zonke izinkinga zokugqwala kwethini likadoti langaphandle ngokuyisisekelo. Lesi sihloko sizochaza zonke izindlela zokwelapha eziyinhloko zokulwa nokugqwala kwethini likadoti langaphandle, sisize abathengi bakhethe imikhiqizo kadoti ehlala isikhathi eside yangaphandle.
1. Izinto Zokusetshenziswa: Isisekelo Sensimbi Ehlanganisiwe Yesisekelo Sokulwa Nokugqwala Kwethini Kadoti
Umzimba webhareli eliyinhloko kanye nohlaka lwemfucuza yethu yangaphandle konke kungasebenzisa ishidi lensimbi elifakwe ngogesi elishisayo njengezinto zokusetshenziswa, okuyisithiyo sokuqala sokulwa nokugqwala kwebhodlela likadoti.
Udoti wensimbi ojwayelekile ungathintana ngqo nomoya namanzi, u-oxidize kanye nokugqwala zingakapheli izinyanga eziyi-1-3 ngaphandle. I-hot-dip galvanizing yakha ungqimba oluqinile lokuvikela i-zinc phezu kwepuleti lensimbi yethini likadoti, ihlukanisa insimbi nomswakama nomoya-mpilo. Ngisho noma ungqimba olungaphezulu lwethini likadoti luklwebhe kancane, ungqimba lwe-zinc luzokhiqiza ukusabela okulwa nokugqwala ukuze kuvinjelwe ukuthi i-matrix yethini likadoti ingagqwali.
Ukuze kufakwe ithini likadoti langaphandle ezindaweni ezinomswakama ogwini, emadolobheni aseningizimu anemvula noma ezindaweni ezisenyakatho ezineqhwa, ithini likadoti lensimbi elihlanganisiwe liyisici esibalulekile sokuvimbela ukugqwala.
2. Umklamo Wesakhiwo Esinezimbobo: Nciphisa Ukunqwabelana Kwamanzi Ukuze Uvikele Ithini Likadoti
Leli khani likadoti elingaphandle elinamagumbi amabili lisebenzisa umklamo ogcwele ombozwe ogobile odongeni lomgqomo, okuwumklamo wesakhiwo osebenzayo wokulwa nokugqwala komgqomo kadoti ongaphandle.
Ithini likadoti lensimbi eliqinile elivaliwe kulula ukuligcina amanzi emvula, indle kanye namanzi ahlanganisiwe ngaphakathi kwethini. Ukucwilisa amanzi isikhathi eside kuzosheshisa ukugqwala kodonga lwangaphakathi lwethini likadoti. Ukusatshalaliswa ngokulinganayo ngemigodi kudoti wethu kungakhipha amanzi asele ngokushesha, kusheshise ukujikeleza komoya ngaphakathi nangaphandle kwethini likadoti, kugweme indawo emanzi yesikhathi eside, futhi kunciphise kakhulu amathuba okugqwala ezindongeni zangaphakathi nezangaphandle zethini likadoti.
Uhlaka oluhlanganisiwe lokusekela udoti lungagcina nezindawo zokukhipha amanzi ezikhaleni phansi, kungabikho ukunqwabelana kwamanzi endaweni engaphansi yokuthintana, okuvimbela ngempumelelo phansi kwethini likadoti ukuthi lingagqwali futhi libhoboze.
3. Inqubo Yokufafaza Ngezingqimba Eziningi: Ukugqoka Okulwa Nokugqwala Okungaphezulu Kwethini Likadoti
Ngemva kokwelashwa nge-galvanizing, yonke imbiza kadoti yangaphandle izodlula ezinqubweni ezintathu zokufafaza phezulu ukuze kuqiniswe ukusebenza kokulwa nokugqwala:
- Ukwelashwa kwangaphambilini kokuncishiswa kwe-phosphate kanye nokususwa kwe-phosphate:Susa uwoyela, amabala okugqwala kanye nokungcola ebusweni bensimbi yethini likadoti ukuqinisekisa inhlanganisela eqinile yengubo kanye ne-matrix yethini likadoti;
- Isendlalelo sokuqala sokulwa nokugqwala:Mboza wonke umzimba wethini likadoti nge-epoxy primer elwa nokugqwala ukuze ugcwalise izikhala ezincane zepuleti lensimbi, uvimbele umthombo wokugqwala;
- Ingubo yempuphu evikela isimo sezulu yangaphandle:Sebenzisa i-powder coating emnyama engacwebezeli i-ultraviolet enamathelayo ebhodweni likadoti. Le coating inamathela kakhulu, ngeke iqhekeke noma iqhekeke ngemva kokuchayeka elangeni isikhathi eside kanye nokugezwa yimvula, futhi ihlukanise amanzi emvula nezinto ezi-asidi ekuthinteni umzimba wensimbi webhodwe likadoti.
Uma kuqhathaniswa nethini likadoti elivamile lopende, ithini likadoti elimbozwe ngempuphu ngeke liwe upende eminyakeni engu-3-5 yokusetshenziswa ngaphandle, okugwema ukugqwala ebusweni bensimbi obuveziwe bethini likadoti ngemva kokukhuhla upende.
4. Umgqomo Ozimele Ongasuswa: Ukulungiswa Okulula Kokwandisa Ikhani Kadoti Impilo Yokulwa Nokugqwala
Isakhiwo esihlukanisiwe salo mfucumfucu ongaphandle ohlungwa kabili singavikela ngokungaqondile ithini likadoti ekugqwaleni. Ithini langaphakathi likadoti lingakhishwa ngokuphelele ngokwahlukana ukuze lihlanzwe. Ijusi likadoti, izinsalela zokudla kanye noketshezi olugqwalisayo yizona zinto eziyinhloko ezibangela ukugqwala kodonga lwangaphakathi lwethini likadoti. Ukuhlukaniswa njalo nokuhlanzwa kwethini likadoti kungasusa ukungcola okugqwalisayo ngokuhamba kwesikhathi, kugweme ukunamatheliswa kwesikhathi eside kokungcola okune-asidi kanye ne-alkaline ukuze kugqwale insimbi yethini likadoti.
Uhlaka oluqinile lokusekela lwethini likadoti luhlukaniswe nomgqomo wokugcina, indle ngeke imanzise uhlaka isikhathi eside, futhi umjikelezo wokulwa nokugqwala weqoqo lonke lethini likadoti uphindwe kabili.
5. Amathiphu Asebenzayo Okulwa Nokugqwala Okusetshenziswa Kwansuku Zonke Kwethini Likadoti Langaphandle
Ngisho nethini likadoti elilwa nokugqwala elisezingeni eliphezulu lidinga ukulungiswa njalo ukuze lihlale isikhathi eside, sifingqa iziphakamiso zokulungisa eziqondiwe zethini likadoti langaphandle:
- Hlanza udonga lwangaphakathi lwembiza kadoti njalo ezinsukwini ezingu-2-3, sula indle eyomile eseleyo, ungashiyi udoti omanzi embiza kadoti ubusuku bonke;
- Gwema uketshezi oluqothulayo njengezinto zokuhlanza ngamakhemikhali ezihlala ngqo phezu kwethini likadoti isikhathi eside, hlanza ngamanzi ahlanzekile ngemva kokuhlanza ithini likadoti;
- Ukuze udoti ubekwe ezindaweni ezisogwini, sula njalo ubuso bodoti ukuze ususe okunamathiselwe kwenkungu kasawoti, usawoti uyisisheshisi esikhulu sokugqwala sodoti wensimbi;
- Uma ungqimba olungaphezulu lwethini likadoti lunemihuzuko emincane, faka upende ovikela ukugqwala ngesikhathi esifanele ukuze uvimbele amanzi ukuthi angangeni esisekelweni sensimbi sethini likadoti.
Isiphetho
Ukwehluleka kokugqwala kuyinkinga enkulu kakhulu yethini likadoti langaphandle, futhi ithini lethu likadoti lensimbi lokuhlunga lithembele ezintweni zokusetshenziswa ezihlanganisiwe, isakhiwo sokukhipha amanzi esingenalutho, ukufutha okulwa nokugqwala okunezingqimba eziningi kanye nomklamo olula ukuwuhlanza ukwakha isethi ephelele yesistimu yokulwa nokugqwala yethini likadoti langaphandle. Kungakhathaliseki ukuthi ithini likadoti lomphakathi lasepaki, ithini likadoti lokuhlukanisa umphakathi noma ithini likadoti langaphandle eliyisikwele lezentengiselwano, le nqubo yokwelapha ukulwa nokugqwala inganciphisa kakhulu imvamisa yokufakwa esikhundleni kwethini likadoti futhi yonge izindleko zokuthenga zesikhathi eside kubathengi.
Uma udinga usayizi, umbala kanye nelogo yokuhlunga eyenziwe ngokwezifiso yethini likadoti elilwa nokugqwala langaphandle, wamukelekile ukuxhumana nethimba lethu ukuthola izixazululo zethini likadoti langaphandle ezenziwe ngokwezifiso.
