Kungani Ama-Rust Converter Engasizi Ngaso sonke isikhathi
Izibazi zihlobisa indoda, kodwa hhayi umzimba wemoto, ikakhulukazi lapho ama-chips kanye nemihuzuko kumapulangwe afika ensimbi, futhi iqala ukuxubha kakhulu. Ngenxa yalokho, kuneminonjana yokugqwala ngendlela yamabala abomvu nemivimbo, okuthi, vele, yonakalise ukubukeka kwemoto. Nokho, lolu uhlangothi olulodwa kuphela lwenkinga...
Uma izinqubo zokugqwala zingamiswa ngesikhathi, khona-ke ngokuhamba kwesikhathi lokhu kuzoholela ekubukeni kwezimbobo ezingxenyeni zomzimba futhi kwenze buthaka isakhiwo sayo samandla. Ngaphezu kwalokho, inkinga iyingozi ikakhulukazi ezimotweni ezindala, njengomthetho, ngokugijima okuhloniphekile. Imizimba yazo inezikhungo eziningi zokugqwala, okuhlanganisa nalezo ezitholakala lapho kuhlangana khona izingxenye zomzimba. Uma izinyathelo zingathathwa ngesikhathi, khona-ke amaphuzu we-welding kanye nama-seams axhuma izingxenye komunye nomunye azolahlekelwa amandla futhi umzimba uzoqala ukusabalala. Yingakho ukuvimbela okufika ngesikhathi kubalulekile ekulweni nokugqwala. Kuhlala kulula ukususa "isiphazamisi esibomvu" kunokuvala imbobo.
Ungamisa kanjani futhi ucekele phansi ukugqwala? Kulezi zinhloso, kusetshenziswa izinhlanganisela ezikhethekile - abaguquli bokugqwala. Ziwuhlobo lwenhlanganisela esebenzayo, okuthi, ukungena ekuphenduleni kwamakhemikhali nge-oxides yensimbi emibili / e-trivalent (empeleni, ukugqwala), yakha inkimbinkimbi engancibiliki kasawoti we-iron phosphate. Konke kucacile futhi kulula…. Kodwa kuphela ekuqaleni. Ukuzijwayeza kubonisa ukuthi ukwakheka kokubunjwa kuhlukile.
Kunama-nuances amaningi, okukodwa futhi okubaluleke kakhulu kuwo yizakhiwo zokukhulelwa komkhiqizo. Kuncike kulokhu ukuthi zonke izikhungo zokugqwala zizoqedwa kanjani ngokucophelela. Into ewukuthi ukugqwala kunesakhiwo esivulekile, okumele sifakwe ngokucophelela futhi singathathi hlangothi ukuze ukugqwala kungazibonakalisi futhi. Kulo mncintiswano lapho amalungiselelo ahlukene abonisa izakhiwo zabo zokusebenza kanye nezimfanelo zabo. Yiqiniso, kunzima ukuhlola ukuthi ukwakheka kufakwe kahle kangakanani futhi, ngaleyo ndlela, ukugqwala okungathathi hlangothi. Isikhathi kuphela esizosho lapha.
Ukuze ungathathi izingozi ngeze, sincoma ukuthi ulalele iseluleko esifakazelwe. Phakathi kwezinhlobonhlobo zezingoma ezithengiswayo, izakhiwo ezinhle ezingenayo zihlukaniswa, isibonelo, ngesiguquli sokugqwala ne-zinc esivela ku-ASTROhim. Ingena kukho konke ukujula kwama-oxides (kufika ku-100 microns) futhi imise izinqubo ze-oxidation yensimbi. Ngesikhathi esifanayo, i-zinc equkethwe ekubunjweni kwayo ithuthukisa izakhiwo zomuthi futhi inikeza ukuvikelwa okwengeziwe kwe-electrochemical (cathodic) ensimbi. Ama-ion asebenzayo, afakwe endaweni ephathwayo, asabela nge-oxidizing agent, ethatha ukushaya. Futhi nakuba kungeyona i-panacea yokugqwala, ibhekana nendima yayo ngokuphelele.
