Ukugalela i-hot-dip yeyona nkqubo iphambili yokuthintela ukugqwala kunye nokugqwalaiipali zezibane zentsimbi. Umgangatho kunye nobukhulu bengubo ye-zinc coating bumisela ngokuthe ngqo ubomi benkonzo yangaphandle ye-light pole. Iinkampani ezininzi zokuthenga nokwakha izibane zobunjineli zihlala zingacacanga malunga nemigangatho yesizwe, ukuhlelwa kobukhulu, kunye neemfuno zokulungelelanisa indawo. Namhlanje, ifektri ye-lamp pole yangaphandle iTianxiang iya kuchaza ngokweenkcukacha imigangatho yokusetyenziswa kwe-HDG street light poles, iiparameter zobukhulu bengubo ye-zinc coating kwiindonga ezahlukeneyo, kunye neenkcukacha zokukhetha imifanekiso yaselunxwemeni nangaphakathi, ikunceda uphephe imigibe yengubo ebhityileyo kunye nezinto ezingezizo ezisemgangathweni.
I. Imigangatho yokuSebenza ngokubanzi yeePali zeZibane zeSitalato zeHDG
Njengesixhobo esiphambili sokukhanyisa kukamasipala kunye nobunjineli beendlela, uqweqwe lwezinki lweepali zokukhanya zesitalato ze-HDG lubalulekile ekumiseleni ukuthintela umhlwa kunye nokugqwala kunye nobomi benkonzo. Iiprojekthi zasekhaya ngokubanzi zilandela umgangatho wesizwe we-GB/T 13912-2022 “IiMfuno zoBugcisa kunye neendlela zoVavanyo lweeMpahla zeGalvanised ezishushu zeZinto zeNtsimbi”. Okwangoku, iiprojekthi zokuthumela ngaphandle zorhwebo lukamasipala nezangaphandle ziya kubhekisa kwimigangatho efanelekileyo ye-ISO yamazwe ngamazwe yegalvanizing.
Umgangatho ngokucacileyo ufuna ukuba yonke ipali yokukhanyisa yentsimbi isebenzise inkqubo yokugaya i-hot-dip yomzimba wonke, ethintela kuphela ukutshiza umphezulu okanye unyango lwe-galvanizing oluyinxenye. Emva kokucola, ukususa umhlwa, kunye nokujika, i-substrate yentsimbi ifakwa kwi-zinc bath enobushushu obuphezulu ukuze yenze umaleko we-zinc odibeneyo ngesinyithi. Olu maleko lunamathela kakhulu kwaye aluxotyulwa lula, nto leyo eyenza ukuba lufaneleke kwiindawo ezintsonkothileyo zangaphandle ezifana namasimi avulekileyo, iindawo eziselunxwemeni, kunye neendawo ezifumileyo, ezine-alkali. Sisiqinisekiso esisisiseko sokukhusela ukugqwala kweepali zokukhanya zesitalato.
II. Iimfuneko zoHlelo lokuThinteka kweLayer yeGalvani eshushu
1. Imigangatho yoButyebi esekwe kuButyebi boDonga lwePole
- Ubukhulu bodonga < 4mm: Ubukhulu obuphakathi be-zinc layer obungekho ngaphantsi kwe-55μm, kunye nobukhulu bendawo obuncinci obungekho ngaphantsi kwe-45μm. Isetyenziswa kakhulu kwiipali ezincinci zentendelezo kunye neepali ezilula zesitalato eziziimitha ezi-3-5.
- Ubukhulu bodonga yi-4mm～6mm: Ubukhulu obuphakathi be-zinc maleko bungadluli kwi-70μm, kunye nobukhulu bendawo obuncinci be-55μm. Kwipali yezibane zesitalato yendlela eqhelekileyo eyi-6-10 yeemitha.
- Ubukhulu bodonga > 6mm: Umgangatho weZinc Coating ongaphantsi kwe-85μm kunye nobuncinci bendawo obuyi-70μm. Isebenza kwisibane esiphezulu semasti esingaphezulu kweemitha ezili-12, indlela ephambili kamasipala, iipali zezibane zendlela.
2. Ukwanda kweMfuno kwiimeko ezahlukeneyo zokusetyenziswa
Iindlela eziqhelekileyo zasezidolophini nezasemaphandleni: Ubukhulu obuqhelekileyo besizwe buyanele, kwaye ubomi benkonzo yiminyaka eli-15-20.
Iindawo zokutshiza ityuwa elunxwemeni, iipaki zoshishino ezineekhemikhali, iindawo ezifumileyo ezisezantsi: uqweqwe olugqunywe nge-hot-dip galvanized kufuneka luqine lube ngaphezu kwe-100μm ubukhulu obupheleleyo ukuze luphucule ukumelana nokutshiza ityuwa kunye nokugqwala kwe-acid/alkali kwaye kuncitshiswe i-oxidation kunye nokugqwala koqweqwe lwezinc.
III. Ukwamkelwa koMgangatho weZinc Coating—Iimfuno eziphantsi
1. Umgangatho weNkangeleko
Umphezulu ofanayo nogudileyo, akukho galvanizing engaphelelanga, amaqamza, ukuxobuka, amaqhuqhuva kunye namabala amnyama. Ii-welds, iiports kunye neeflanges mazingabi namacala afileyo kwaye azina galvanizing engaphelelanga.
2. Umgangatho wokunamathela
Ingubo ye-zinc ayizukuqhekeka okanye ixobuke ngexesha lokubetha kwesando kunye novavanyo olunqamlezileyo, kwaye kufuneka ibotshelelwe ngokuqinileyo kwisiseko sentsimbi.
3. Indlela yoVavanyo
Ukuhlolwa kweesampuli ezininzi kusetyenziswa i-zinc coating thickness gauge. Amacandelo aphezulu, aphakathi, nasezantsi epali kunye nesiseko seflange kufuneka ahlangabezane nomgangatho. Ukuba naluphi na uhlobo lwesampuli lungaphumeleli, lonke iqela kufuneka lihlolwe kwakhona kwaye liphinde lisetyenzwe.
Ubukhulu bomaleko we-hot-dip galvanized bumisela ngokuthe ngqo ubomi benkonzo yangaphandle yeepali zokukhanyisa zentsimbi. Zombini ukuthengwa kobunjineli kunye nokwenza ngokwezifiso umenzi kufuneka zihambelane ngokungqongqo nobukhulu be-galvanized obuhambelanayo ngokobukhulu bodonga obuqhelekileyo besizwe.Ifektri yesibane se-galvanized yangaphandleI-Tianxiang iyala ukusebenzisa i-galvanization engeyiyo eqhelekileyo ukuqinisekisa ukusetyenziswa okuzinzileyo kwexesha elide kweprojekthi zokukhanyisa.
