Idiphu eshushu umbhobho wentsimbi, kwaziwa njengeidiphu eshushu umbhobho wagalvanized, ngumbhobho wensimbi ofakwe kwipayipi yensimbi ngokubanzi ukuphucula ukusebenza kwayo kwenkonzo. Ukusetyenzwa kwayo kunye nomgaqo wokuvelisa kukwenza ukuba isinyithi esityhidiweyo siphendule kunye ne-iron substrate ukuvelisa i-alloy layer, ukwenzela ukuba i-substrate kunye neengubo zinokudibaniswa. Injani iimibhobho yentsimbi enezinki eshushuisetyenzisiwe? Ukuhamba kwenkqubo yombhobho wentsimbi eshushu-diphu wahlulwe ngokwala manyathelo alandelayo:
1.Ukuhlanjwa kwealkali: eminye imibhobho yentsimbi inamabala e-oyile kumphezulu, ngoko ke ukuhlamba ialkali kuyafuneka.
2.I-Pickling: i-hydrochloric acid ikhethwa ukukhanga ukususa ulusu lwe-oxide kumphezulu wombhobho wentsimbi.
3.Ukucoca: ikakhulu ukususa i-asidi eshiyekileyo kunye netyuwa yentsimbi encanyathiselwe kumphezulu wombhobho wentsimbi.
4.Izixhobo zokuntywila: indima ye-flux kukususa zonke izinto ezingcolileyo kumbhobho wensimbi, uqinisekise ukudibanisa okucocekileyo phakathi kombhobho wensimbi kunye nesisombululo se-zinc, kwaye wenze isambatho esihle.
5.Ukomisa: ikakhulu ukuthintela umbhobho wentsimbi ukuba ungantywiliselwa kwimbiza ye-zinc kunye nokuqhushumba.
6.I-Hot dip galvanizing: ubushushu be-zinc liquid kwi-zinc pot iya kulawulwa ngokungqongqo kwi-450 + 5 ° C, umbhobho wentsimbi uya kufakwa kwisithando somlilo kwaye uqengqeleke kwi-zinc dipping spirals kumatshini we-galvanizing. Le mijikelo mithathu inezigaba ezahlukeneyo, nto leyo eyenza ukuba umbhobho wentsimbi uthambekele kwi spirals. Ngokujikeleza kwe-spirals, umbhobho wentsimbi uhla uye ezantsi kwelinye icala ukwenza i-engile yokuthambekela, kwaye emva koko ungene kwibhafu ye-zinc, iqhubeke ihambela ezantsi, kwaye iwela ngokuzenzekelayo kumzila wesilayidi kwimbiza ye-zinc; Xa umbhobho wentsimbi uphakanyiselwe kwindawo yokuxuba magnetic, iya kutsalwa kwaye ihanjiswe kumzila wevili lokutsala.
7.Ukuvuthela kwangaphandle: umbhobho wentsimbi udlula kwiringi yokuvuthela yangaphandle ukucinezela umoya kwaye uvuthele ulwelo lwezinki olugqithisileyo kumbhobho wentsimbi ukuze ufumane inkangeleko egudileyo necocekileyo.
8.Ukukhupha ngaphandle: Ubungakanani be-zinc bunokulawulwa kwaye ukusetyenziswa kwe-zinc kunokuncitshiswa ngokunciphisa ngokufanelekileyo isantya sokukhupha.
9.Ukuvuthela kwangaphakathi: susa ulwelo lwezinki olugqithisileyo kumphezulu wangaphakathi wombhobho wentsimbi ukuze ufumane indawo engaphakathi egudileyo necocekileyo. Ulwelo lwezinki olususiweyo lwenza i-zinc powder ukuze lusetyenziswe kwakhona.
10.Ukupholisa amanzi: ubushushu betanki yokupholisa amanzi buya kulawulwa ku-80 ℃, kwaye umbhobho wegalvanized uya kupholiswa.
11.I-Passivation: isisombululo sokugqithisa sitshizwa kumbhobho ogqityiweyo weringi yokuvuthela ukwenza umphezulu wombhobho ugqithe. Emva kweringi yokuvuthela yangaphandle, isisombululo esigqithisiweyo sivuthelwa ngomoya oxinzelelweyo.
12.Ukuhlola: umbhobho wensimbi owenziwe ngesinyithi uwela kwibhentshi yokuhlola, emva kokuhlolwa, umbhobho ongekhoyo we-galvanized ufakwa kwibhasikithi yenkunkuma, kwaye umbhobho ogqityiweyo upakishwe kwaye ufakwe kwindawo yokugcina.
