I-Zinc yinkqubo ye-metallurgical reaction.Ukusuka kwindawo yokujonga i-microscopic, inkqubo ye-dip galvanizing eshushu yi-balance balance, ibhalansi yobushushu kunye ne-zinc iron exchange equilibrium.Xa umsebenzi wentsimbi wantywiliselwa malunga ne-450℃I-zinc enyibilikisiweyo yolwelo, ubushushu begumbi lolwelo lwe-zinc ukufunxa ubushushu bomsebenzi, bufikelela ngaphezulu kwe-200℃, ukusebenzisana kwe-zinc kunye nentsimbi kwacaca, i-zinc, isinyithi singena kumphezulu.Njengoko iqondo lobushushu lesixhobo sokusebenza lisondela ngokuthe ngcembe kwiqondo lobushushu le-zinc etyhidiweyo, umphezulu we-workpiece uyilwe ngomlinganiselo owahlukileyo we-zinc iron alloy layer, i-hierarchical structure ye-zinc coating, kunye nexesha elongeziweyo, ukukhula komaleko we-alloy plating ohlukeneyo kunika isantya esahlukileyo sesantya.Ukusuka kwimbono macro, ukusebenza inkqubo workpiece ngasentla entywiliselwa zinc elulwelo, zinki ulwelo abilayo kwenzeka xa zinki, reaction yentsimbi ngokuthe ngcembe ulungelelwano, umphezulu zinc ngokuthe ngcembe uzolile.Iworkpiece yenziwe.Umphezulu we-zinc, iqondo lobushushu le-workpiece lehliswa kancinci ukuya ngaphantsi kwe-200℃, ukusabela wayeka zinc, intsimbi, idiphu eshushu ukutyabeka ngamagalvanized inobungqingqwa ezimisele.
Ubukhulu bezinto eziphambili zokugquma i-zinc: isiseko sentsimbi, uburhabaxa bomphezulu wentsimbi, intsimbi yezinto ezisebenzayo isilicon kunye nomxholo wephosphorus kunye nokuhanjiswa, uxinzelelo lwangaphakathi lwentsimbi, ijiyometri yesixhobo sokusebenza, inkqubo yokuntywila eshushu. .Imigangatho yangoku yamazwe ngamazwe kunye Chinese yahlulwe ngokwamacandelo ngokwentsimbi ukutyeba, ubukhulu zinc ukutyabeka ukutyeba kunye nokuzoba lendawo kufuneka ifikelele ubukhulu ehambelanayo, ukugqiba zinc ukutyabeka ukusebenza anticorrosion.Ubukhulu bentsimbi obuhlukeneyo bomsebenzi, ukufezekisa ukulingana kwe-thermal, kunye ne-zinc ion exchange equilibration ngamaxesha ahlukeneyo, ukutyeba okubangelwayo kuyahluka.Ubukhulu obuqhelekileyo bomgangatho wokugquma busekelwe kwindlela yamava okugalela kwimveliso yoshishino, ubuninzi bendawo yobuninzi be-zinc yokwambathisa kuthathelwa ingqalelo ukusasazwa okungalinganiyo kokwaleka kunye neemfuno zokukhusela umhlwa amava afunekayo.Ke ngoko, imigangatho ye-ISO, imigangatho ye-ASTM, imigangatho ye-JIS kunye nemigangatho yaseTshayina imfuneko yokuqina kokuqina kwe-zinc yahluke kancinci, iyafana.
Ubukhulu bengubo ye-zinc bumisela ukusebenza kweendawo zokubeka i-anticorrosion.Kwi-3 mm ezantsi komgangatho weplate yentsimbi ebhityileyo igudileyo, kunzima ukufumana i-coating etyebileyo kwimveliso yeshishini, ukongeza, ayihambelani nobukhulu bentsimbi ye-zinc yokucwenga kwaye iya kuchaphazela amandla okuncamathela kokutya kunye kunye. i-substrate kunye nomgangatho wembonakalo yokugquma.Utyatyazo olungqindilili luya kubangela ukuba inkangeleko yokwambathisa irhabaxa, ixobulwa ngokulula, iinxalenye zeplating azikwazi ukumelana nongquzulwano kwinkqubo yokuphatha kunye nofakelo.Ukuba kukho iintsimbi ezininzi ezisebenzayo ze-silicon kunye ne-phosphorus, imveliso ye-industrial inzima kakhulu, i-silicone umxholo wentsimbi enempembelelo phakathi kwendlela yokukhula ye-zinc-iron alloy layer.
