Umbhobho odityanisiweyo owenziwe ngesinyithi
Inkcazelo emfutshane:
Ukuze kuphuculwe ukuxhathisa kwe-corrosion yeepayipi zetsimbi, iibhobho zensimbi eziqhelekileyo zenziwe nge-galvanized.Imibhobho yentsimbi ekhuselweyo ihlulwe ibe yi-galvanizing yediphu eshushu kunye ne-electro galvanizing.I-hot-dip galvanizing layer ingqindilili, ixabiso le-electro galvanizing liphantsi, kwaye umphezulu awugudi kakhulu.Umbhobho odityanisiweyo ovuthela ioksijini: usetyenziswa njengombhobho wentsimbi ovuthelayo.Ngokuqhelekileyo, umbhobho wensimbi odityanisiweyo omncinci usetyenziswa, kunye neenkcukacha ezisibhozo ze-3 / 8-2 intshi.Yenziwe nge-08, 10, 15, 20 okanye i-195-q235 yentsimbi.Ukuze kuthintelwe ukubola, unyango lwe-aluminizing kufuneka lwenziwe.
Ukuhlelwa kwemibhobho yegalvanized
Umbhobho wentsimbi owenziwe ngesinyithi wahlulwe ube ngumbhobho wokucwenga obandayo kunye nombhobho wokutyabeka oshushu.Eyangaphambili ivaliwe kwaye le yokugqibela iye yakhuthazwa ngurhulumente ukuba isetyenziswe okwethutyana
Umbhobho wediphu oshushu
Umbhobho wediphu oshushu owenziwe ngesinyithi kukwenza isinyithi esinyibilikisiweyo sisabele nge-iron matrix ukuvelisa umaleko wealloyi, ukuze kudityaniswe imatrix kunye nokwaleka.Ukugalela idiphu eshushu kukuvuthela umbhobho wentsimbi kuqala.Ukuze ukususa intsimbi oxide kumphezulu umbhobho yentsimbi, emva pickling, icocwe ammonium chloride okanye zinc chloride isisombululo aqueous okanye ammonium chloride kunye nezinki chloride exutywe nesisombululo enamanzi itanki, kwaye emva koko ithunyelwe kwidiphu eshushu galvanizing itanki.I-Hot dip galvanizing ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende.
Umbhobho obandayo wegalvanized
Ukugquma okubandayo kukugalela i-electro.Isixa se-galvanizing sincinci kakhulu, kuphela i-10-50g / m2.Ukumelana nomhlwa kwayo kwahluke kakhulu kuleyo yombhobho wegalvanized wediphu eshushu.Ukuze kuqinisekiswe umgangatho, abaninzi abavelisi bemibhobho ye-galvanized rhoqo abayisebenzisi i-electro galvanizing (i-cold plating).Kuphela loo mashishini amancinci anezixhobo ezincinci kunye nezixhobo ezindala asebenzisa i-electro galvanizing, ngokuqinisekileyo, ixabiso labo lincinci.UMphathiswa wolwakhiwo uphelise ngokusesikweni umbhobho obandayo osemva, kwaye akuvumelekanga ukusebenzisa umbhobho obandayo wamazinki njengombhobho wamanzi kunye negesi kwixesha elizayo.
Idiphu eshushu yombhobho wentsimbi: imatriksi yombhobho wentsimbi idibana nesisombululo esinyibilikisiweyo sokucwenga ukwenza umaleko we-zinc ferroalloy okwaziyo ukurusa kunye nesakhiwo esixineneyo.Uluhlu lwe-alloy luhlanganiswe ne-zinc ecocekileyo kunye ne-matrix yepayipi yensimbi.Ngoko ke, inokumelana ne-corrosion enamandla.
Umbhobho wensimbi obandayo: i-zinc layer yi-electroplating layer, kwaye i-zinc layer ihlukaniswe kwi-matrix yentsimbi yombhobho.Uluhlu lwe-zinc luncinci, kwaye i-zinc layer ifakwe nje kwi-matrix yepayipi yensimbi, elula ukuwa.Ngoko ke, ukuxhathisa kwayo kukonakala.Kwizindlu ezitsha, akuvumelekanga ukusebenzisa imibhobho yentsimbi ebandayo njengemibhobho yokuhambisa amanzi.
