Izakhiwo zensimbiZisetshenziswa kabanzi ezakhiweni zesimanje, emabhulohweni, nasezitshalweni zezimboni ngenxa yamandla azo aphezulu, isisindo esincane, kanye nemijikelezo emifushane yokwakha. Uma kuqhathaniswa nezakhiwo zekhonkrithi zendabuko, izakhiwo zensimbi zivumela ububanzi obukhulu, izinhlobo zokwakha eziguquguqukayo, kanye nokulethwa kwephrojekthi okusheshayo. Lezi zinzuzo zenza insimbi ibe yinto efanelekile yezakhiwo ezinkulu zomphakathi, izikhungo zokuthutha, kanye nama-workshop ezimboni. Kodwa-ke, insimbi nayo iyazwela kakhulu ekugqwaleni kwe-electrochemical uma ivezwa ezindaweni zemvelo. Umswakama, umoya-mpilo, usawoti, kanye nokungcola kwezimboni kungabangela ngokushesha ukusabela kokugqwala. Ukugqwala akugcini nje ngokuthinta ukubukeka kwesakhiwo kodwa futhi kunciphisa ingxenye ephumelelayo yamalungu ensimbi. Ngokuhamba kwesikhathi, le nqubo isongela ngqo ukuphepha kwesakhiwo kanye nokuqina kwesikhathi eside. Ngenxa yalesi sizathu, ukususwa kokugqwala kwesayensi kanye nokwelashwa kokulwa nokugqwala kuyizinyathelo ezibalulekile kubunjiniyela besakhiwo sensimbi.
Ukulungiswa Komphezulu: Isisekelo Sokuvikelwa Kokulwa Nokugqwala
Ukususwa kokugqwala komhlaba kuyisinyathelo sokuqala nesibaluleke kakhulu kunoma yiluphi uhlelo lokuvikela ukugqwala. Ikhwalithi yalo inquma ngqo ukunamathela kanye nokuphila kwenkonzo kwezembozo ezilandelayo. Uma ukugqwala, isikali sokugaya, noma uwoyela kuhlala phezu kwensimbi, ngisho nohlelo lokugqoka oluhle kakhulu luzohluleka ngaphambi kwesikhathi.
Ekukhiqizweni kwezimboni, ukuqhuma okunamandla noma ukuqhuma ngokudubula kuyindlela esetshenziswa kakhulu yokususa ukugqwala. Izinhlayiya ezinamandla ezisheshayo zithinta ubuso bensimbi futhi zisuse isikali se-oxide, ukugqwala, kanye nokungcola. Amaphrojekthi amaningi adinga izinga lokuhlanzeka kobuso elingu-Sa 2.5. Kuleli zinga, ubuso bensimbi bubonisa umbala wensimbi ofanayo ongenawo ukugqwala noma isikali esibonakalayo, futhi unezinga elithile lobulukhuni. Le phrofayili elukhuni ithuthukisa kakhulu amandla okubopha okwenziwa phakathi kwensimbi kanye nopende.
Ukuhlanza amathuluzi ngesandla nangamandla kusetshenziswa kakhulu ezindaweni zokwakha noma ezindaweni lapho ukuqhumisa ngomshini kungenzeki khona. Izisebenzi zithembele kumabhulashi ensimbi, ama-angle grinder, noma ama-sanding disc ukuze zisuse ukugqwala. Le ndlela inokusebenza okuphansi kanye nokusebenza okulinganiselwe. Ngokuvamile ifinyelela amazinga okuhlanzeka eSt 2 noma St 3. Nakuba le ndlela ingenakuqhathaniswa nekhwalithi yokuqhumisa, isadlala indima ebalulekile emsebenzini wokulungisa kanye nokulungisa kwendawo.
Izinhlelo Zokumboza: Indlela Yokuvikela Eyinhloko
Ngesikhathi sokukhiqiza nokugcinwa kwezingxenye zesakhiwo sensimbi, izinhlelo zokumboza ezinezingqimba eziningi zivame ukusetshenziswa. Lezi zinhlelo zandisa impilo yesevisi ngokuhlanganiswa kwezindlela zokuvikela ngokomzimba kanye nokuvikela amakhemikhali.
Uhlelo olujwayelekile lokumboza luqukethe i-primer, i-intermediate coat, kanye ne-topcoat. I-primer inikeza umugqa wokuqala wokuzivikela ekugqwaleni futhi iqinisekisa ukunamathela okuqinile ku-substrate yensimbi. Ama-primer acebile nge-epoxy zinc asetshenziswa kabanzi kulesi sigaba. I-zinc powder ngaphakathi kwe-coating isebenza njenge-anode yomhlatshelo. Ngesenzo se-electrochemical, i-zinc iyagqwala ngokukhethekile futhi ivikele insimbi engaphansi ekugqwaleni.
Uboya obuphakathi bukhulisa kakhulu ukujiya koboya futhi buthuthukisa ukusebenza kwesithiyo. Upende we-iron oxide we-epoxy micaceous uyindlela evamile yokukhetha. Isakhiwo sawo sombala ofana nepuleti sivimba ngempumelelo ukungena komhwamuko wamanzi nomoya-mpilo. Lokhu kuthuthukisa ubuningi boboya futhi kubambezele izinqubo zokugqwala.
I-topcoat igxile ekumelaneni nesimo sezulu kanye nokubukeka. Izingxenye zensimbi eziveziwe zivame ukusebenzisa ama-topcoat e-polyurethane noma e-fluorocarbon. Lezi zinto zinikeza ukumelana okuhle kakhulu nemisebe ye-ultraviolet. Zivimbela ukushibilika nokunyamalala ngenkathi zinikeza umbala wokugcina wesakhiwo. I-topcoat esezingeni eliphezulu igcina kokubili isivikelo kanye nobuhle iminyaka eminingi.
Abakhiqizi abanolwazi bavame ukufaka izembozo ngokucophelela okukhulu. Isibonelo, iHarbin Dongan Building Sheets Company isebenzisa izindlela eziningi zokufutha ngesikhathi sokukhiqiza izingxenye zensimbi ukuqinisekisa ukuthi ugqinsi lwefilimu eyomile lungaba ama-micron angu-75. Lo mkhuba uthuthukisa kakhulu ukumelana nokugqwala futhi wandisa isikhathi senkonzo.
Izinyathelo Ezikhethekile Zokulwa Nokugqwala
Ezindaweni ezisesimweni esinzima kakhulu noma ezindaweni okunzima ukuzinakekela, izindlela zokuvikela ezithuthukisiwe zivame ukudingeka.
Ukufaka i-hot-dip galvanizing kuhilela ukucwilisa izingxenye zensimbi ezihlanziwe ku-zinc encibilikisiwe cishe ku-450°C. Le nqubo yakha ungqimba olujiyile noluqinile lwe-zinc-iron alloy phezu komhlaba. Ukufaka i-hot-dip galvanizing kunikeza isivikelo esivelele ezindaweni ezisogwini, ezindaweni zokufutha usawoti, kanye nezimo ezinomswakama ohlala njalo.
Insimbi eshintshashintshayo imelela esinye isisombululo esisebenzayo. Ngokufaka izinto ezixubile njengethusi, i-chromium, ne-nickel, insimbi yakha ungqimba lokugqwala oluqinile noluqinile ebusweni bayo. Lolu ngqimba luvimbela ukugqwala okwengeziwe futhi lufeza umphumela "wokuvikela ukugqwala" ngaphandle kokumbozwa okwengeziwe.
Ekuphetheni, ukususa ukugqwala okuphumelelayo nokuvikela ukugqwala kubalulekile ekuphepheni, ukuqina, kanye nokubukeka kwezakhiwo zensimbi. Ukulungiswa kwendawo efanele, izinhlelo zokumboza eziklanywe kahle, kanye nezinyathelo ezikhethekile ezifanele ndawonye kuqinisekisa ukuthi izakhiwo zensimbi zisebenza ngokwethembeka kuyo yonke impilo yazo yokusebenza ehlosiwe.
