I-Hot-dip galvanizingyinkqubo apho izinto zetsimbi okanye inxalenye enomgangatho ococekileyo intywiliselwa kwisisombululo se-zinc esinyibilikisiweyo, kwaye umaleko we-zinc yensimbi yenziwa phezu komhlaba ngokusabela komzimba kunye neekhemikhali kwi-interface. I-Hot-dip galvanizing, ekwabizwa ngokuba yi-hot-dip galvanizing kunye ne-hot-dip galvanizing, yindlela esebenzayo yesinyithi yokuchasana nomhlwa, esetyenziselwa ikakhulu ukulwa nokubola komphezulu wezakhiwo zesinyithi, izibonelelo kunye nemathiriyeli kumashishini ahlukeneyo. Ngoko ke zeziphi iimpawuumbhobho wentsimbi ongenamthungo oshushu-diphu?

1. Iziqwenga ezingwevu zobukhulu obahlukeneyo kumphezulu wombhobho wentsimbi engenamthungo ngumahluko wombala wegalvanizing, eyingxaki enzima kwishishini langoku lokugalela, ikakhulu elinxulumene nezinto zomkhondo eziqulethwe kumbhobho wentsimbi ngokwawo kunye namacandelo angaphakathi. ibhafu ye-zinc. I-stain ayichaphazeli ukusebenza kwe-anti-corrosion yombhobho wensimbi, kuphela umahluko kwimbonakalo.

2. Kukho amanqaku aphakanyisiweyo ngokuthe ngcembe kumphezulu wombhobho ngamnye wentsimbi engenamthungo, ezizinc zonke, ezenziwe ngokupholisa kunye nokuqiniswa kolwelo lwezinc oluqukuqela phantsi eludongeni lombhobho emva kokuba umbhobho wentsimbi engenamthungo uthatyathwe ngaphandle. imbiza yezinc.

4. Abanye abathengi baya kusebenzisa uxhulumaniso lwe-groove kwinkqubo yokusebenzisa umbhobho we-galvanized seamless steel ukucinezela i-groove. Ngenxa yomaleko we-zinc eshinyeneyo wombhobho wensimbi ongenamthungo oshushu-dip, phantsi kwesenzo samandla angaphandle awonakalisayo, inxalenye yomaleko owenziwe ngamazinki iya kuqhekeka kwaye ixovule, nto leyo engenanto yakwenza nomgangatho wombhobho wentsimbi engenamthungo ngokwawo. .

5. Abanye abathengi baya kusabela ukuba kukho ulwelo olutyheli kumbhobho wentsimbi ongenamthungo (olu lulwelo lubizwa ngokuba yi-passivation liquid), olunokuthi lugqithise umphezulu wesinyithi. Ngokuqhelekileyo isetyenziselwa unyango lwe-post-plating ye-galvanized, cadmium kunye nezinye iingubo. Injongo kukwenza umgangatho ongaphezulu kwi-coat surface enokuthintela ukuphendula okuqhelekileyo kwesinyithi, ukuphucula ukunyameka kwayo, kunye nokwandisa i-aesthetics yemveliso. Inokuphucula ngokufanelekileyo ukuchasana kwe-corrosion yombhobho wensimbi kunye nokwandisa ubomi benkonzo yomsebenzi.

Umphumo wokukhusela we-hot-dip galvanized layer kumbhobho wensimbi ongenamthungo ungcono kakhulu kunepeyinti okanye umaleko weplastiki. Kwinkqubo ye-galvanizing ye-hot-dip, i-zinc isasazeka ngentsimbi ukwenza i-zinc-iron intermetallic compound layer, oko kukuthi, i-alloy layer. Uluhlu lwe-alloy luboshwe nge-metallurgical kwintsimbi kunye ne-zinc, eyomeleleyo kune-bond phakathi kwepeyinti kunye nentsimbi. Umaleko oshushu-dip owenziwe ngegalvanized utyhileke kwimo engqongileyo ye-atmospheri kwaye awuwi kumashumi eminyaka de ube ngumhlwa ngokupheleleyo ngokwendalo.

Iteknoloji yegalvanizing ye-hot-dip yeumbhobho wentsimbi ongenamthungoingahlulwa ngokubanzi ibe yidiphu yokucwenga kunye nokuvuthela:

1. Dip Plating. Pholisa ngamanzi ngokuthe ngqo emva kokucwiliswa emanzini. Ubungakanani obuqhelekileyo be-zinc layer bukhulu kunama-microns angama-70, ngoko ke ixabiso le-galvanizing liphezulu, kwaye inani le-zinc likhulu. Kwimekobume ye-atmospheric eqhelekileyo iminyaka engaphezu kwama-50, kukho imikhondo ecacileyo yokuhamba kwe-zinc, kwaye umbhobho wensimbi omde kakhulu ungafakwa kwi-16m.

2. Vuthela iplating. Emva kokufakwa kwegalvanizing, ingaphandle iyavuthelwa kwaye ingaphakathi lipholile. Ubungakanani obuqhelekileyo be-zinc layer bukhulu kunama-microns angama-30, ixabiso liphantsi, kwaye ukusetyenziswa kwe-zinc kuncinci. Emva kweminyaka engaphezu kwama-20 yokusetyenziswa kwindawo eqhelekileyo ye-atmospheri, phantse akukho mkhondo wolwelo lwezinc unokubonwa. Umgca wokuvelisa i-zinc ngokubanzi 6-9m.
