Okokuqala, umqondo uhlukile
I-Hot dip galvanizing iyisilondolozi sensimbi esisebenzayo, esisetshenziswa ikakhulukazi ezimbonini ezahlukahlukene zezakhiwo zensimbi.Izingxenye zensimbi ngemva kokususwa kokugqwala zicwiliswa kusisombululo se-zinc esincibilikisiwe esicishe sibe ngu-500 ℃, ukuze ingaphezulu lelungu lensimbi linamathiselwe ungqimba lwezinc, ukuze kudlale inhloso yokunqanda ukubola.I-zinc ye-dip eshisayo iwukucwilisa ilungu lensimbi ngemva kokususwa kokugqwala oketshezini lwezinki oluncibilikisiwe cishe ngo-600℃, ukuze ingaphezulu lelungu lensimbi linamathele ngongqimba lwezinki.Ugqinsi lwengqimba ye-zinc abukho ngaphansi kuka-65μm wepuleti elincane elingaphansi kuka-5mm, futhi lingabi ngaphansi kuka-86μm kupuleti eliwugqinsi elingaphezu kuka-5mm.Ukuze udlale inhloso yokuvimbela ukugqwala.
Okwesibili, inqubo yokukhiqiza ihlukile
I-galvanizing ibhekisela kubuchwepheshe bokwelapha obungaphezulu bokunamathisela ungqimba lwezinc phezu kwensimbi, ingxubevange noma ezinye izinto ezizodlala indima yobuhle nokuvimbela ukugqwala.Indlela eyinhloko esetshenziswayo manje ukugalela amanzi ashisayo.Kodwa-ke, imboni ye-hot dip galvanizing iye yathuthukiswa ngokuthuthuka ngokushesha kwemigqa ebandayo eminyakeni engama-30 edlule.Inqubo yokukhiqiza yeshidi elishisiwe elinamakethi ashisayo ikakhulukazi lihlanganisa: ukulungiswa kwepuleti eluhlaza → ukwelashwa kwangaphambilini → ukucwenga okushisayo → ukwelashwa kwangemva kokucwenga → ukuhlolwa komkhiqizo ophelile nokunye.
Ngokomkhuba ngokuvamile ngokusho hardware eziyisisekelo lashukumisa ngaphambi Plating ukwelashwa indlela, inqobo nje uma engathinti amanzi angagcina 5 ~ 7 iminyaka noma ngaphezulu ngaphandle nokugqwala, yebo, uma ukuhlolwa amanzi anosawoti, ngeke. isikhathi esingaphezu kwamahora ama-4.I-zinc dip eshisayo iwukusebenzisa isisombululo se-zinc tin ukumboza i-hardware, futhi isikhathi sokuvimbela ukugqwala cishe siphindwe kahlanu kune-galvanizing yendabuko.Ukwakhiwa okuvamile kwangaphandle ukusebenzisa i-dip zinc eshisayo, futhi ukuhlolwa kwamanzi anosawoti kungenza cishe amahora angama-36.
Njengamanje, kuyaqashelwa ukuthi indlela engcono kakhulu yokwelashwa kwendawo yokuvikela ukugqwala ukwenza i-dacron rust.Ngokuvamile, izingxenye zezimoto ziye zasetshenziswa le ndlela yokuvimbela ukugqwala.Ukuhlolwa kwamanzi anosawoti ngokuvamile kuthatha amahora angaphezu kwama-96.Kodwa uma i-hardware isetshenziswa ezimeni ezimbi kakhulu, kukhona nabantu abasebenzisa "i-asphalt" okuyitiyela ukwenza ukwelashwa kwendawo.
Okwesithathu, ukusetshenziswa kobuchwepheshe obuhlukahlukene
I-Hot dip galvanizing wukucwecwa kwe-zinc layer phezu kwe-Angle steel, insimbi yesiteshi nezinye izinsimbi ukuze kuzuzwe ukubonakala kulula nokuvimbela ukugqwala kwensimbi.Izitshalo zokucubungula i-zinc ezishisayo zisebenzisa isisombululo se-zinc tin ukuvimbela ukugqwala endaweni yokusebenza.Lobu buchwepheshe obusha bunganweba isikhathi sokugqwala kuze kufike izikhathi ezinhlanu, okuvame ukusetshenziswa ekwakhiweni kwangaphandle.Ngoba isimiso sesenzo asifani, ngakho-ke indima ye-workpiece ayifani.Ukubonakala kwesitshalo se-dip zinc esishisayo ukukhulisa kuphela ububanzi besenzo.
