Ukuze kuphuculwe ukuxhathisa kwe-corrosion yeepayipi zetsimbi, iibhobho zensimbi eziqhelekileyo zenziwe nge-galvanized.Imibhobho yentsimbi ekhuselweyo ihlulwe ibe ziindidi ezimbini: i-hot-dip galvanizing kunye ne-electro-galvanizing.I-hot-dip galvanizing layer inzima, ixabiso le-electro-galvanizing liphantsi, kwaye umphezulu awugudi kakhulu.

Umbhobho odityanisiweyo ovuthela ioksijini: Isetyenziswa njengentsimbi yokwenza umbhobho ovuthela ioksijini, ngokubanzi imibhobho yentsimbi edityanisiweyo enedayamitha encinci, eneenkcukacha ezisibhozo ukusuka kwi-3/8 ukuya kwi-intshi ezi-2.Yenziwe nge-08, 10, 15, 20 okanye i-195-Q235 yentsimbi yentsimbi, ukwenzela ukuthintela ukubola, kuyimfuneko ukwenza unyango lwe-aluminizing.

Uninzi lwezindlu ezindala zisebenzisa imibhobho eyenziwe ngamazinki.Imibhobho yentsimbi esetyenziselwa igesi kunye nokufudumeza ikwayimibhobho eyenziwe ngamazimba.Imibhobho eyenziwe ngegalvanized isetyenziswa njengemibhobho yamanzi.Emva kweminyaka embalwa yokusetyenziswa, i-rust eninzi kunye nokungcola kuveliswa kwimibhobho, kwaye amanzi atyheli aphuma ngaphandle angcolise nje i-sanitary ware., Kwaye ixutywe neebhaktheriya ezizala kudonga lwangaphakathi olungalinganiyo, umhlwa ubangela umxholo wesinyithi esinzima kakhulu emanzini, nto leyo ebeka impilo yabantu engozini.Ngeminyaka yoo-1960 noo-1970, amazwe aphuhlileyo ehlabathini aqalisa ukuphuhlisa iindidi ezintsha zemibhobho kwaye ngokuthe ngcembe avala imibhobho eyenziwe ngamazi.Abaphathiswa abane kunye neekomishoni ezibandakanya i-Ofisi yoLwakhiwo lwase-China bakhuphe uxwebhu olucacisa ukuba imibhobho ye-galvanized iye yavalwa ukusuka kwi-2000 ukuya phambili.Imibhobho yegalati ayifane isetyenziswe kwimibhobho yamanzi abandayo kwiindawo ezisandul' ukwakhiwa emva kowama-2000, kwaye imibhobho enezinki isetyenziselwa imibhobho yamanzi ashushu kwezinye iindawo.

Ulwahlulo lombhobho wegalvanized

Imibhobho yentsimbi yahlulwe yaba yimibhobho ebandayo enezinki kunye nemibhobho eyenziwe ngamatha ediphu eshushu.Eyangaphambili ivaliwe, kwaye le yokugqibela iye yakhuthazwa ngurhulumente ukuba isebenziseke okwethutyana.

Umbhobho ofakwe igalvanized eshushu
Umbhobho owenziwe ngesinyithi oshushu-dip kukwenza isinyithi esinyibilikisiweyo kunye ne-matrix yentsimbi iphendule ukuvelisa umaleko we-alloy, ukuze i-matrix kunye ne-coating zidibaniswe.I-Hot-dip galvanizing kukuchola umbhobho wentsimbi kuqala.Ukuze kususwe i-iron oxide kumphezulu wombhobho wentsimbi, emva kokuchola, icocwa kwitanki ye-ammonium chloride okanye i-zinc chloride isisombululo esinamanzi okanye isisombululo esinamanzi esixubeneyo se-ammonium chloride kunye ne-zinc chloride, kwaye emva koko ithunyelwe kwi-In. itanki yokufaka idiphu eshushu.I-Hot-dip galvanizing ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende.

Umbhobho obandayo wamazinki
I-galvanizing ebandayo i-electro-galvanizing, kwaye inani le-galvanizing lincinci kakhulu, kuphela i-10-50g / m2, kwaye ukuxhathisa kwayo kwe-corrosion kubi kakhulu kunemibhobho ye-galvanized eshushu.Uninzi lwabavelisi bemibhobho ye-galvanized rhoqo abayisebenzisi i-electro-galvanized (i-cold plating) ukuze kuqinisekiswe umgangatho.Kuphela loo mashishini amancinci anezixhobo ezincinci kunye neziphelelwe lixesha asebenzisa i-electro-galvanization, kwaye ngokuqinisekileyo amaxabiso abo aphantsi kakhulu.UMphathiswa wezoKwakha ubhengeze ngokusemthethweni ukuba imibhobho ebandayo ene-galvanized technology ephelelwe lixesha kufuneka isuswe, kwaye imibhobho ebandayo ayinakuvunyelwa ukuba isetyenziswe njengemibhobho yamanzi kunye negesi kwixesha elizayo.

Umbhobho wentsimbi owenziwe ngesinyithi oshushu-diphu: Imatrix yombhobho wentsimbi idibana nentshukumo entsonkothileyo yomzimba kunye neekhemikhali kunye nesisombululo esityhidiweyo sokucwenga ukwenza umaleko we-alloy we-zinc-iron onganyangekiyo kunye nesakhiwo esibambeneyo.Uluhlu lwe-alloy luhlanganiswe kunye ne-zinc ecocekileyo kunye ne-matrix yombhobho wensimbi.Ngoko ke, ukuxhathisa kwayo kwe-corrosion kunamandla.

Umbhobho obandayo wentsimbi:Uluhlu lwe-zinc luluhlu lwe-electroplated, kwaye i-zinc layer kunye ne-substrate yombhobho wensimbi ibekwe ngokuzimeleyo.I-zinc layer incinci, kwaye i-zinc layer ibambelela nje kwi-substrate yombhobho wensimbi kwaye kulula ukuwa.Ke ngoko, ukuxhathisa kwayo kukonakala.Kwizindlu ezisanda kwakhiwa, akuvumelekanga ukusebenzisa imibhobho yentsimbi ebandayo njengemibhobho yokuhambisa amanzi.

Ubugcisa

Inkqubo yokuvelisa intsimbi engatyiwa inala manyathelo okuvelisa alandelayo:

a.Ukulungiswa kwentsimbi ejikelezayo;b.Ukufudumeza;c.Ukugqobhoza okushushu;d.Sika intloko;e.Ukuvunwa;f.Ukusila;g.Ukuthambisa;h.Ukuqengqeleka okubandayo;i.Ukunciphisa amafutha;j.Isisombululo sonyango lobushushu;k.Ukulungelelanisa;l.Sika ityhubhu;m.Ukuvunwa;n.Uvavanyo lwemveliso.

Ukubonelela ngenkqubo jikelele kuphela, kwaye ezona nkcukacha zininzi ziyimfihlo zomenzi ngamnye

Iimfuno zobuchwephesha ukuba imibhobho yegalvanized kufuneka ihlangabezane

1. Uphawu kunye nokwakheka kweekhemikhali
Ibakala kunye nokwakhiwa kweekhemikhali zetsimbi kwiibhobho zetsimbi ezinobumba kufuneka zihambelane nebakala kunye nokwakheka kweekhemikhali zetsimbi kwiibhobho ezimnyama ezichazwe kwi-GB 3092.

2. Indlela yokuvelisa
Indlela yokuvelisa umbhobho omnyama (i-furnace welding okanye i-welding yombane) ikhethwe ngumenzi.I-Hot-dip galvanizing isetyenziselwa ukwenza igalvanizing.

3. Umsonto kunye nokudibanisa umbhobho
3.1 Kwimibhobho yensimbi ene-galvanized ehanjiswa ngeentambo, iintambo kufuneka zenziwe ngoomatshini emva kwe-galvanizing.Intambo kufuneka ihambelane nemigaqo ye-YB 822.
3.2 Amalungu emibhobho yentsimbi kufuneka ahambelane neYB 238;izidibanisi zemibhobho yentsimbi ethambileyo kufuneka zihambelane neYB 230.

4. Iimpawu zoomatshini Iipropathi zomatshini zemibhobho yentsimbi ngaphambi kokuba i-galvanizing kufuneka ihlangabezane neemfuno ze-GB 3092.

5. Ukufana komgangatho we-galvanized layer Umbhobho wensimbi ovunyiweyo kufuneka uvavanywe ukufana komgangatho we-galvanized layer.Isampuli yepayipi yensimbi ayiyi kujika ebomvu (umbala wobhedu) emva kokuntywiliselwa kwisisombululo se-sulfate yethusi ngamaxesha angama-5 alandelelanayo.

6. Uvavanyo lokugoba olubandayo Umbhobho wensimbi owenziwe ngesinyithi kunye nobubanzi obungadluli kwi-50mm kufuneka ube phantsi kovavanyo lokugoba olubandayo.I-angle yokugoba yi-90 °, kwaye i-radius yokugoba ngamaxesha angama-8 ububanzi bangaphandle.Akukho nto yokuzalisa ngexesha lovavanyo, kwaye i-weld yesampuli kufuneka ibekwe ngaphandle okanye inxalenye ephezulu yendlela yokugoba.Emva kovavanyo, akufuneki kubekho iintanda kunye ne-peeling ye-zinc layer kwisampuli.

7. Uvavanyo loxinzelelo lwamanzi Uvavanyo loxinzelelo lwamanzi kufuneka lwenziwe kwi-clarinet.I-Eddy yangoku yokubona isiphene ingasetyenziswa endaweni yovavanyo loxinzelelo lwamanzi.Uxinzelelo lovavanyo okanye ubungakanani besampulu yothelekiso yovavanyo lwangoku lwe-eddy iya kuhlangabezana neemfuno ze-GB 3092.
