ukuhlelwa
Ityhubhu yesikwere evuthelweyo yahlulwe yaba ityhubhu eshushu yagalvanized square kunye netyhubhu ebandayo yesikwere yegalvanized ukusuka kwinkqubo yokuvelisa.Kungenxa yokuba ukusetyenzwa kwezi zityhubhu zimbini zesquare zahlukile ukuba zineempawu ezininzi ezahlukeneyo zomzimba kunye neekhemikhali.Ngokuqhelekileyo, zihluke ngamandla, ukuqina kunye neempawu zomatshini.
Idiphu eshushu ityhubhu yesikwere enesikwere: yityhubhu yesikwere edityanisiweyo emva kokuba ipleyiti yentsimbi okanye umcu wentsimbi iqengqeleke kwaye ibunjwe, kwaye yenziwa emva kothotho lweempendulo zemichiza kwidiphu eshushu yediphu ngesiseko sale tyhubhu yesikwere.Inkqubo yemveliso yetyhubhu ye-galvanized square eshushu-dip ilula, kwaye ukusebenza kwemveliso kuphezulu kakhulu, kwaye kukho iintlobo ezininzi kunye neenkcukacha.Le ityhubhu yesikwere idinga izixhobo ezimbalwa kunye neemali, ezifanelekileyo ukuveliswa kwabakhiqizi betyhubhu encinci ye-galvanized square.Kodwa ngokwamandla, amandla alolu hlobo lombhobho wentsimbi angaphantsi kakhulu kunombhobho osikwere ongenamthungo.
Umbhobho obandayo wesikwere owenziwe ngamazi
Kwaye i-galvanized square tube ebandayo kukusebenzisa umgaqo we-galvanizing ebandayo kwityhubhu yesikwere esetyenziselwa ukwenza ityhubhu yesikwere ibe nokusebenza okuchasene nokubola.Ngokwahlukileyo kwi-galvanizing eshushu, i-galvanizing ebandayo yokugquma isebenzisa umgaqo we-electrochemical ukuthintela ukubola, ngoko ke kuyimfuneko ukuqinisekisa uqhagamshelwano olupheleleyo phakathi komgubo we-zinc kunye nentsimbi ukuvelisa i-electrode enokubakho umahluko, ngoko ke unyango lwentsimbi lubaluleke kakhulu.
Umahluko phakathi kwegalvanizing eshushu kunye nebandayo
Ityhubhu yesikwere evuthisiweyo ibandakanya ityhubhu yesikwere esinezibane ezishushu kunye ne-electrogalvanized square tube.I-hot-dip galvanized square tube ibandakanya indlela emanzi, indlela eyomileyo, indlela ye-zinc ehamba phambili, indlela yokunciphisa i-oxidation, njl njl. Umahluko omkhulu phakathi kweendlela ezahlukeneyo zokugalela idiphu eshushu yintoni na indlela esetyenziselwa ukwenza umphezulu womzimba wombhobho ukuphucula umgangatho. yokugalela emva kokucocwa kweasidi yokucoca kumbhobho wentsimbi.Okwangoku, indlela eyomileyo kunye nendlela ye-redox isetyenziswa kakhulu kwimveliso, kwaye iimpawu zabo ziboniswa kwitheyibhile.Umphezulu we-zinc layer ilula kakhulu, ixinene kwaye ifana;Iipropati ezilungileyo zoomatshini kunye nokuchasana nokubola;Ukusetyenziswa kwe-Zinc yi-60% ~ 75% ephantsi kuneyo ye-galvanizing eshushu.I-Electrogalvanizing inobuxhakaxhaka bobugcisa obuthile, kodwa kufuneka isetyenziselwe ukutyabeka kwicala elinye, ukugquma okumacala amabini kunye nobukhulu obahlukileyo bokwaleka kumphezulu wangaphakathi nangaphandle, kunye netyhubhu ebhityileyo yokugalela.
