Umbhobho wentsimbi engenamthungo
Inkcazelo emfutshane:
Umbhobho wentsimbi ongenamthungo owenziwe ngesinyithi ushushu-diphu ufakwe igalvanized, ngoko ke ubungakanani be-zinc plating buphezulu kakhulu, umyinge wokutyabeka we-zinc ungaphezulu kwama-microns angama-65, kwaye ukuxhathisa kwayo kukudleka kwahluke kakhulu kunombhobho wamanzi ashushu.Umenzi wemibhobho ehlala igalvanized rhoqo unokusebenzisa umbhobho obandayo wamanzi njengombhobho wamanzi kunye negesi.I-zinc yokugquma kombhobho wentsimbi ebandayo ifakwe kwi-electroplated layer, kwaye i-zinc layer yahlulwe kwi-substrate yombhobho wentsimbi.Uluhlu lwezinc luncinci kwaye lulula ukuwa ngenxa yokuba lufakwe kwi-substrate yombhobho wensimbi.Ngoko ke, ukuxhathisa kwayo kukonakala.Akuvumelekanga ukusebenzisa umbhobho wentsimbi ebandayo njengomthombo wamanzi kwizakhiwo ezitsha zokuhlala.

Umbhobho wentsimbi galvanized isetyenziswa ngokubanzi kulwakhiwo, oomatshini, kumgodi wamalahle, kushishino lwemichiza, amandla ombane, izithuthi zikaloliwe, ishishini lemoto, uhola wendlela, ibhulorho, isikhongozeli, amaziko ezemidlalo, oomatshini bezolimo, oomatshini bepetroleum, oomatshini bokukhangela kunye namanye amashishini okuvelisa.
Idiphu eshushu umbhobho wentsimbi: idiphu eshushu umbhobho owenziwe ngamazimba kukwenza isinyithi esinyibilikisiweyo sisabele nge-matrix yentsimbi ukuvelisa umaleko wealloyi, ukuze imatrix kunye nokwaleka kudityaniswe.Ukuze kususwe i-iron oxide phezu kombhobho wentsimbi, emva kokukhetha, umbhobho wentsimbi ucocwa nge-ammonium chloride okanye i-zinc chloride isisombululo esinamanzi okanye i-tank yesisombululo esixutywe se-ammonium chloride kunye ne-zinc chloride, kwaye emva koko ithunyelwe kwitanki ye-galvanizing eshushu.I-Hot dip galvanizing ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende.Iimpendulo ezintsonkothileyo zomzimba kunye neekhemikhali phakathi kwe-substrate yombhobho wentsimbi otshisiweyo kunye nebhafu etyhidiweyo ikhokelela ekwakhiweni kwe-zinc ferroalloy layer kunye ne-compact corrosion resistance structure.Uluhlu lwe-alloy luhlanganiswe kunye ne-zinc ecocekileyo ye-zinc kunye ne-matrix yepayipi yombhobho, ngoko ke ukuxhathisa kwe-corrosion kunamandla.
Umbhobho wensimbi obandayo obandayo: umbhobho obandayo owenziwe nge-electro galvanized, ubungakanani be-zinc plating yi-10-50g / m2 kuphela, kwaye ukuxhathisa ukubola kwayo kwahluke kakhulu kumbhobho we-galvanized dip.Ukuze kuqinisekiswe umgangatho, abaninzi abavelisi bemibhobho ye-galvanized rhoqo abayisebenzisi i-electro galvanizing (i-cold plating).Kuphela ezo zincinci, izixhobo ezidala zamashishini amancinci okusebenzisa i-galvanizing, ewe, amaxabiso azo aphantsi.UMphathiswa wolwakhiwo ubhengeze ngokusesikweni ukupheliswa kwemibhobho ebanda ngasemva ebanda ceke, kwaye akuvumelekanga ukusebenzisa imibhobho ebanda yamazinki njengemibhobho yamanzi nerhasi.I-zinc yokugquma kombhobho wentsimbi ebandayo ifakwe kwi-electroplated layer, kwaye i-zinc layer yahlulwe kwi-substrate yombhobho wentsimbi.Uluhlu lwezinc luncinci kwaye lulula ukuwa ngenxa yokuba lufakwe kwi-substrate yombhobho wensimbi.Ngoko ke, ukuxhathisa kwayo kukonakala.Akuvumelekanga ukusebenzisa umbhobho wentsimbi ebanda kakhulu njengombhobho wokuhambisa amanzi kwizakhiwo ezitsha zokuhlala.
