Dhuumaha birta galvanized kulul, sidoo kale loo yaqaantuubo galvanized maquufin kulul, waa tuubo bir ah oo galvanized si ay u wanaajiso waxqabadka adeegeeda. Nidaamkeeda iyo mabda'a wax-soo-saarka ayaa ah inay ka dhigto birta dhalaalaysa inay la falgasho substrate-ka birta si ay u soo saarto lakabka alloy, si substrate iyo daahan la isku daro. Sidee yihiinDhuumaha birta galvanized kululla farsameeyay? Habka socodka tuubada birta galvanized kulul-muquuqida waxa loo qaybiyaa tallaabooyinka soo socda:
1.Dhaqidda Alkali: Tuubooyinka birta qaarkood waxay leeyihiin wasakh saliid oo korka ah, sidaas darteed dhaqidda alkali waa loo baahan yahay.
2.Qaadista: aashitada hydrochloric ayaa loo doortaa in la qaado si looga saaro maqaarka oksaydhka ee dusha tuubada birta ah.
3.Luqluqashada: inta badan si meesha looga saaro aashitada haraaga ah iyo milixda birta ee ku xiran dusha tuubada birta.
4.Aaladaha wax-ku-daridda: doorka qulqulka waa in laga saaro dhammaan wasakhda dusha tuubada birta, la hubiyo xidhiidhka nadiifka ah ee u dhexeeya tuubada birta iyo xalka zinc, iyo samaynta dahaar wanaagsan.
5.Qalajinta: inta badan si looga hortago in tuubada birta ah lagu dhex milmo dheriga zinc iyo qarxinta.
6.Galvanizing Hot Dip: heerkulka dareeraha zinc ee dheriga zinc waa in si adag loo xakameeyaa 450+5 ° C, tuubada birta waa in la geliyaa foornada galvanizing oo lagu rogo saddexda xabbo ee zinc-ka-dhuujinta ee mashiinka galvanizing. Saddexda wareegyadu waxay leeyihiin wejiyo kala duwan, taasoo ka dhigaysa tuubada birta inay u janjeerto wareegyada. Wareegga wareegyada, tuubada birta waxay hoos u socotaa hal dhinac si ay u sameyso xagal u janjeera, ka dibna waxay gashaa qubeyska zinc, waxay sii wadaa inay hoos u sii socoto, oo si toos ah ugu dhacdo xadiidka slide ee dheriga zinc; Marka tuubada birta kor loo qaado korka isku dhafka birta, waa la soo jiidan doonaa oo loo wareejin doonaa jidka giraangiraha jiidaya.
7.Duubista dibadda: tuubada birta ahi waxay soo martaa giraanta afuufista dibadda si ay hawada u cadaadiyo oo ay u afuufo dareeraha zinc ee xad-dhaafka ah ee tuubada birta si ay u hesho muuqaal siman oo nadiif ah.
8.Soo saarista: Qadarka zinc waa la xakamayn karaa oo isticmaalka zinc waa la yarayn karaa iyada oo si habboon loo yareeyo xawaaraha jiidista.
9.Duubista gudaha: ka saar dareeraha zinc-ka ee xad-dhaafka ah ee dusha sare ee tuubada birta si aad u hesho dusha gudaha ah oo siman oo nadiif ah. Dareeraha zinc ee la saaray ayaa ka dhigaya budada zinc dib-u-warshadaynta.
10.Qaboojinta biyaha: heerkulka haanta qaboojinta waa in lagu xakameeyaa 80 ℃, iyo tuubada galvanized waa in la qaboojiyo.
11.Passivation: Xalka passivation ayaa lagu buufiyaa tuubada dhammaatay ee giraanta dharbaaxada si dusha tuubada looga dhigo mid la dhaafo. Ka dib giraanta dharbaaxada dibadda, xalka xad-dhaafka ah ayaa lagu afuufi hawo ciriiri ah.
12.Kormeerka: tuubada galvanized birta ah waxay ku dhacdaa kursiga kormeerka, kormeerka ka dib, tuubada galvanized ee maqan ayaa lagu ridayaa dambiisha qashinka, tuubada dhammaatay waa la soo ururiyaa oo lagu dhejiyaa kaydinta.
