Izinto ezichaphazela ubukhulu be-zinc steel grating coating ikakhulu: ukubunjwa kwesinyithi se-grating yensimbi, uburhabaxa bomphezulu we-grating yensimbi, umxholo kunye nokusabalalisa izinto ezisebenzayo i-silicon kunye ne-phosphorus kwi-grating yensimbi, uxinzelelo lwangaphakathi lwe-grating yensimbi, imilinganiselo yejometri ye-workpiece yentsimbi, kunye nenkqubo yokugaya i-hot-dip ye-grating yensimbi. Imigangatho yangoku yamazwe ngamazwe kunye ne-Chinese hot-dip galvanizing yahlulahlulwe ngokwamacandelo ngokobunzima bepleyiti. Umyinge wobunzima kunye nobukhulu bendawo yengubo ye-zinc kufuneka ifikelele kubukhulu obuhambelanayo ukumisela ukusebenza kwe-anti-corrosion ye-coating ye-zinc. Ixesha elifunekayo ukufezekisa ukulingana kwe-thermal kunye ne-zinc-iron exchange equilibrium ye-steel grating workpieces yobunzima obuhlukeneyo buhluke, kwaye ubukhulu be-coating eyenziwe buye bahluke. Umyinge wokwaleka ubukhulu kumgangatho ngamava emveliso yemveliso yexabiso esekelwe kwindlela yokufaka i-galvanizing ekhankanywe ngasentla, kunye nobukhulu bendawo lixabiso lamava afunekayo ukuze kuthathelwe ingqalelo ulwabiwo olungalinganiyo lobuninzi be-zinc kunye neemfuno zokuxhathisa ukubola kwengubo. Ke ngoko, umgangatho we-ISO, umgangatho we-ASTM waseMelika, umgangatho we-JS waseJapan kunye nomgangatho waseTshayina uneemfuno ezahlukileyo kancinci kubunzima be-zinc coating, ezifanayo. Ngokwamalungiselelo omgangatho oshushu wokuntywila we-GB B 13912-2002 weRiphabhlikhi yaBantu baseTshayina. Imigangatho ye-zinc yokwaleka kwi-hot-dip galvanized metal gratings ngolu hlobo lulandelayo: Kuba i-hot-dip galvanized gratings yentsimbi kunye nobukhulu obukhulu kune-6mm okanye ilingana ne-6mm, i-avareji ye-zinc yokwambathisa ubukhulu kwi-hot-dip galvanized metal grating kufuneka ibe mkhulu kune-85 microns, kwaye ubukhulu bendawo kufuneka bube bukhulu kune-70 microns. Kwigrayiti yentsimbi efakwe kwidiphu eshushu enobunzima obungaphantsi kwe-6mm nangaphezulu kwe-3mm, umyinge we-zinc yokwambathisa ubukhulu kwigrayiti yentsimbi efakwe esinyithi eshushu kufuneka ibe ngaphezulu kwe-70 yemicrons, kwaye ubukhulu bendawo kufuneka bube bukhulu kune-55 microns. Kwigrayiti yentsimbi eshushu ediphu enobunzima obungaphantsi kwe-3mm nangaphezulu kwe-1.5mm, umyinge we-zinc yokwambathisa ubukhulu kwigrayiti yentsimbi etshisiweyo kufuneka ibe nkulu kune-55 microns, kwaye ubukhulu bendawo kufuneka bube bukhulu kune 45 microns.
Indima kunye nefuthe le-hot-dip galvanizing coating thickness
Ubuninzi be-at-dip galvanized coating kwi-grating yensimbi inquma ukusebenza kwe-anti-corrosion ye-grating yensimbi. Abasebenzisi banokukhetha ubukhulu be-zinc bokwambathisa obuphezulu okanye obuphantsi kunomgangatho. Kunzima ukufumana i-coating ebanzi kwimveliso ye-industrial gratings yensimbi encinci kunye nomphezulu ogudileyo ongaphantsi kwe-3mm. Ukongeza, ubuninzi be-zinc obungalinganiyo nobukhulu bentsimbi yentsimbi buya kuchaphazela amandla okudibanisa phakathi kwengubo kunye ne-substrate kunye nomgangatho wokubonakala kwengubo. Ilifu elishinyene kakhulu lokutyabeka liza kubangela ukuba inyameko ibonakale irhabaxa kwaye kulula ukuyixobula. I-grating yensimbi edibeneyo ayikwazi ukujamelana nokungqubana ngexesha lokuthutha kunye nokufakwa. Ukuba kukho izinto ezisebenzayo ngakumbi i-silicon kunye ne-phosphorus kwizinto eziluhlaza ze-grating yensimbi, kunzima kakhulu ukufumana i-coating encinci kwimveliso yezoshishino. Oku kungenxa yokuba umxholo we-silicon kwintsimbi uchaphazela indlela yokukhula yomaleko we-alloy phakathi kwe-zinc kunye nentsimbi, eya kubangela ukuba (, isigaba se-zinc-iron alloy layers sikhule ngokukhawuleza kwaye (ukuya kumphezulu we-coating, kubangele umphezulu wokugquma omdaka, okwenza i-grey i-adhesion kunye ne-adhesion embi. Ngoko ke, njengoko kuxoxwe ngasentla, kukho ukungaqiniseki kokukhula kwe-van gal. ukufumana uluhlu oluthile lokutyabeka kwimveliso yokwenyani Ubukhulu obuchazwe kumgangatho wokutshisa i-galvanizing ye-steel grating lixabiso elibonakalayo eliveliswe emva kwenani elikhulu leemvavanyo, kuthathelwa ingqalelo izinto ezahlukeneyo kunye neemfuno, kwaye kunengqiqo.
