Imigca ye-galvanizing zixhobo ezikhethekileyo zokuvelisa ezenzelwe inkqubo yokufaka i-galvanizing, ebandakanya ukusebenzisa i-zinc kwintsimbi okanye isinyithi ukukhusela ukubola. Inkqubo ibalulekile kumashishini ahlukeneyo, kubandakanywa ukwakhiwa, iimoto, kunye nokuvelisa, apho ubomi obude kunye nokuqina kwamalungu esinyithi kubaluleke kakhulu.Imigca yokugalelaukudibanisa amacandelo amaninzi abalulekileyo, kubandakanywa izixhobo zokuphatha izinto kunye neeyunithi zokubuyisela kunye nokuvuselela, ukuqinisekisa imveliso esebenzayo.
Inkqubo yokugaya
Inkqubo yokwenziwa kwegalvanizing ibandakanya amanqanaba amaninzi, kubandakanywa ukulungiswa komphezulu, ukugalela, kunye nasemva konyango. Inqanaba ngalinye libalulekile ekufezekiseni ai-zinc ekumgangatho ophezului-coating ebambelela ngokuqinileyo kwi-substrate kwaye inika ukhuseleko oluhlala ixesha elide.
I-1.Ukulungiswa komphezulu: Ngaphambi kokufakwa kwentsimbi okanye intsimbi, kufuneka icocwe ngokucokisekileyo ukuze isuse naziphi na izinto ezingcolisayo ezifana nomhlwa, ioli okanye ukungcola. Oku kudla ngokufezekiswa ngokudityaniswa kokucoca ngoomatshini kunye nokunyangwa kweekhemikhali, kubandakanywa ukukha kwisisombululo se-asidi. Injongo kukudala indawo ecocekileyo yokubambelela ngokufanelekileyo kwengubo ye-zinc.
2.I-Galvanizing: Xa umphezulu ulungisiwe, isinyithi sintywiliselwa kwibhafu ye-zinc etyhidiweyo, idla ngokufudumeza ukuya kuma-450 ° C (842 ° F). I-zinc isabela ngentsimbi kwintsimbi ukwenza uluhlu lwezinki-iron alloy layers, ezithi ke zigqunywe ngumaleko we-zinc ecocekileyo. Yile bhondi yesinyithi enika intsimbi ekhandisiweyo ukuxhathisa kwayo okugqwesileyo kokutya.
I-3.Unyango lwasemva: Emva kwe-galvanizing, imveliso edibeneyo inokuthi iqhube iinkqubo ezahlukeneyo emva kokunyanga, ezifana nokucima okanye ukunyamezela, ukuphucula ukusebenza kwe-zinc coating. Olu nyango lunokuphucula inkangeleko yomphezulu ofakwe igalvanized kwaye luphucule ngakumbi ukuxhathisa umhlwa.
Indima yezixhobo zokuphatha izinto
Izixhobo zokuphatha izinto eziphathekayo zidlala indima ebalulekileyo ekusebenzeni kakuhle kunye nokusebenza komgca we-galvanizing. Esi sixhobo sinoxanduva lokuhamba, ukugcinwa kunye nokulawulwa kwezinto eziphathekayo kuyo yonke inkqubo ye-galvanizing. Iintlobo eziphambili zeizixhobo zokuphatha izintoesetyenziswa kwimigca yokufaka intsimbi ibandakanya:
1.Abahambisi: Ezi nkqubo zihambisa iinxalenye zentsimbi kumanqanaba ahlukeneyo enkqubo yokufaka igalvanizing, ukusuka ekulungisweni komphezulu ukuya kwitanki yokugalela. Iinkqubo zokuthutha ezizenzekelayo zinokunciphisa kakhulu iindleko zabasebenzi kunye nokunyusa isantya sokuvelisa.
I-2.I-Crane kunye ne-Hoist: Kwiindawo ezinkulu okanye ezinzima, ii-cranes kunye nee-hoists ziyimfuneko ekuphakamiseni nasekubekeni izinto ngaphakathi komgca we-galvanizing. Ezi nkqubo ziqinisekisa ukuba iinxalenye zibekwe ngokukhuselekileyo nangokuchanekileyo kwiitanki zegalvanizing kunye nezinye iindawo zokucubungula.
I-3.IiRakhi zokuGcinwa: Ukugcinwa ngokufanelekileyo kwezinto eziluhlaza kunye neemveliso ezigqityiweyo zibalulekile ekugcineni indawo yokuvelisa ehlelekile nesebenzayo. Iiracks zokugcina zinceda ukwandisa indawo kwaye ziqinisekise ukuba imathiriyeli ifikeleleka ngokulula xa kuyimfuneko.
Isixhobo sokubuyisela i-Flux kunye nokuhlaziywa kwakhona
Ukubuyiselwa kwe-Flux kunye neeyunithi zokuvuselela ziyinxalenye ebalulekileyo yemigca ye-galvanizing yanamhlanje. I-Flux yikhemikhali yekhemikhali esetyenziswa ngexesha lenkqubo yokugaya ukuphucula umgangatho we-zinc coating. Inceda ukuthintela i-oxidation yendawo yesinyithi kwaye ikhuthaza ukunamathela okungcono kwe-zinc. Nangona kunjalo, i-flux inokungcoliseka ngokuhamba kwexesha, okukhokelela ekunciphiseni ukusebenza kakuhle kunye nokwanda kweendleko.
IiRefluxers ziyasombululale ngxaki ngokuqhubeka nokucoca kunye nokuvuselela isisombululo se-flux. Le nkqubo ibandakanya amanyathelo amaninzi:
I-1.I-Filtration: Hlunga i-flux engcolileyo ukususa ukungcola kunye neengqungquthela ezinokuchaphazela umgangatho wenkqubo ye-galvanizing.
Unyango lwe-2.Chemical: I-flux ehluziweyo inokunyangwa ngamachiza ukubuyisela iimpawu zayo kunye nokusebenza kwayo. Oku kunokubandakanya ukongeza iikhemikhali ezithile ukulungelelanisa isisombululo se-flux.
3. Ukurisayikilishwa kwakhona: I-flux esetyenzisiweyo inokuphinda isetyenziswe kwaye isetyenziswe kwakhona kwinkqubo yokufaka i-galvanizing, ukunciphisa inkunkuma kunye nokunciphisa iindleko zokusebenza. Oku akuphuculi nje ukusebenza kakuhle komgca wegalvanizing, kodwa kukwanceda ukufezekisa izenzo ezizinzileyo zemveliso.
Isishwankathelo, imigca ye-galvanizing iyinkimbinkimbi kwaye iyimfuneko yokuvelisa iimveliso zensimbi. Ukudityaniswa kweizixhobo zokuphatha izintokunye neeyunithi zokubuyisela kunye nokuhlaziywa kwakhona ziphucula ukusebenza kakuhle, umgangatho kunye nokuzinza kwenkqubo ye-galvanizing. Njengoko imfuno yeshishini lezinto ezihlala ixesha elide kunye ne-corrosion-resistant iqhubeka nokukhula, ukubaluleka kwemigca yegalvanizing ephucukileyo kuya kunyuka kuphela, kubenza babe yinxalenye ebalulekileyo yemveliso yanamhlanje.
