Injongo yokufaka igalvanizing ebandayo kunye nokutshisa okushushu kweiipali zezibane zelangakukuthintela ukubola kunye nokwandisa ubomi benkonzo yezibane zesitalato zelanga, ngoko yintoni umehluko phakathi kwezi zimbini?
1. Imbonakalo
Ukubonakala kwe-galvanizing ebandayo igudile kwaye ikhanya. Umaleko we-electroplating kunye nenkqubo yokugqithisa umbala ubukhulu becala butyheli kunye nohlaza, kunye nemibala esixhenxe. Umaleko we-electroplating kunye nenkqubo yokudlula emhlophe bubluish mhlophe, kwaye nemibala kancinane kwi-engile ethile yokukhanya kwelanga. Kulula ukuvelisa "ukutsha kombane" kwiimbombo kunye nemida yentonga eyinkimbinkimbi, eyenza i-zinc layer kule nxalenye ibe nzima. Kulula ukwenza i-current kwikona yangaphakathi kwaye ivelise indawo engaphantsi kwegrey, eyenza i-zinc layer kule ndawo incinci. Intonga ayiyi kuba neqhuma le-zinc kunye ne-agglomeration.
Inkangeleko ye-galvanizing eshushu irhabaxa kancinane kunaleyo ye-galvanizing ebandayo, kwaye imhlophe ngokwesilivere. Ukubonakala kulula ukuvelisa iimpawu zamanzi zenkqubo kunye namaconsi ambalwa, ngokukodwa ekupheleni kwentonga.
Umaleko we-zinc we-galvanizing eshushu kancinane ungqindilili ngokuphindwe kaninzi kune-galvanizing ebandayo, kwaye ukuxhathisa komhlwa kwawo kukwaphindaphinda amaxesha amaninzi elo lokugalela kombane, kwaye ixabiso lawo ngokwendalo liphezulu kakhulu kunelo lokugalela okubandayo. Nangona kunjalo, ekuhambeni kwexesha, i-galvanizing eshushu kunye nokuthintela umhlwa iminyaka engaphezu kwe-10 iya kuthandwa kakhulu kune-galvanizing ebandayo kunye nokuthintela umhlwa iminyaka eyi-1-2 kuphela.
2. Inkqubo
I-Cold galvanizing, eyaziwa ngokuba yi-galvanization, kukusebenzisa izixhobo ze-electrolytic ukubeka intonga kwisisombululo esiqulethe ityuwa ye-zinc emva kokucoca kunye nokuchola, kwaye udibanise ipali engafanelekanga yesixhobo se-electrolytic. Beka ipleyiti ye-zinc kwelinye icala lentonga ukuyidibanisa kwipali echanekileyo yesixhobo se-electrolytic, ukudibanisa unikezelo lwamandla, kwaye usebenzise intshukumo yendlela yangoku ukusuka kwipali echanekileyo ukuya kwipali engafanelekanga ukufaka umaleko we-zinc. kwindawo yokusebenza; I-galvanizing eshushu kukususa i-oyile, ukuhlamba i-asidi, ukudipha iyeza kwaye womise i-workpiece, kwaye emva koko uyintywilisele kwisisombululo se-zinc etyhidiweyo ixesha elithile, uze uyikhuphe.
3. Isakhiwo sokugquma
Kukho umaleko we-brittle compound phakathi kwengubo kunye ne-substrate ye-galvanizing eshushu, kodwa le nto ayinayo impembelelo enkulu ekuxhathiseni ukubola kwayo, kuba i-coating yayo i-zinc ecocekileyo, kwaye i-coating ifana ngokufanayo, ngaphandle kwe-pores, kwaye ayikho. kulula ukugrunjwa; Nangona kunjalo, i-coating ye-galvanizing ebandayo yenziwe nge-athomu ye-zinc, ehambelana nomzimba. Kukho iipores ezininzi kumphezulu, kwaye kulula ukuchatshazelwa yindalo kunye nokugqwala.
4. Umahluko phakathi kwezi zimbini
Kumagama ezi zibini, kufuneka siwazi umahluko. I-Zinc kwimibhobho yentsimbi ebandayo ifumaneka kwiqondo lokushisa, ngelixa i-zinc kwi-galvanizing eshushu ifumaneka kwi-450 ℃ ~ 480 ℃.
5. Ubukhulu bokugquma
Ubukhulu bengubo ebandayo yokugquma ngokuqhelekileyo yi-3 ~ 5 μ m kuphela. Kulula kakhulu ukusetyenzwa, kodwa ukuxhathisa ukubola kwayo akulunganga kakhulu; I-galvanized coating eshushu-dip idla ngokuba ne-10 μ Ukumelana nokubola kobukhulu be-m nangaphezulu kungcono kakhulu, okumalunga namaxesha aphindwe kabini kwipali yesibane esibanda.
6. Umahluko wexabiso
Ukutshiza okushushu kuyinkathazo kakhulu kwaye kufuna kakhulu kwimveliso, ngoko ke amanye amashishini anezixhobo ezindala ngokwentelekiso kunye nesikali esincinci ngokubanzi athatha imo ebandayo yokugalela kwimveliso, ephantsi kakhulu kwixabiso kunye neendleko; Nangona kunjalo,abavelisi begalvanizing eshushu-dipzisesikweni kakhulu kwaye zinkulu ngokwesikali. Banolawulo olungcono kumgangatho kunye neendleko eziphezulu.
Lo mahluko ungasentla phakathi kwegalvanizing eshushu kunye neengqele ezibandayo zeepali zezibane zesitalato kwabelwana ngazo apha. Ukuba iipali zezibane zesitalato zelanga kufuneka zisetyenziswe kwiindawo ezinxweme, kufuneka ziqwalasele ukumelana nomoya kunye nokumelana nokubola, kwaye musa ukudala iprojekthi yenkunkuma ngenxa yokuhaha kwexeshana.
