Iposwe kwi 2015-10-26Ithekhnoloji yeDacromet yaqala kwiminyaka yamashumi asixhenxe kwinkulungwane yama-20, eUnited States, eChina ngeminyaka yee-1980 yazisa iteknoloji yeDacromet, kwaye ngokutya kunye nokufunxa, kwaye ngokuthe ngcembe baqonde izixhobo zenkqubo kunye neDacromet fluid yendawo.Ngo-2002, i-State Administration of quality supervision, inspection and Quarantine yakhupha umgangatho wesizwe "GB/T18684-2002 zinc chromium coating conditions".
Itekhnoloji yeDacromet itsale ingqalelo ngakumbi nangakumbi yabaphandi kunye namashishini anxulumene neempawu zayo eziphezulu.Iimpawu zokwaleka zeDacromet:
I-1, indawo enobubele iDacromet indlela evaliweyo yomjikelo, kwi-Dacromet yokwambathisa kunye nenkqubo yokunyanga yokuphuphuma komphunga wamanzi kunye nenani elincinci lezinto eziphilayo zingaphakathi komda omiselwe ngurhulumente, akukho nkqubo yemveli ye-electroplating ekuveliseni ubuninzi bezingcolisi. kunye namanzi amdaka.Ngoko ke, i-Dacromet ngandlela-thile inokuthi ibhekwe njengeteknoloji "eluhlaza".
I-2, ukuxhathisa okuphezulu kokubola kweDacromet yokwaleka isiphumo sokulwa ne-antirust kumaxesha angama-7-10 aphezulu kunalawo e-electro galvanized, idiphu eshushu okanye indlela yokwaleka yepeyinti kunye nomgangatho weDacromet yokwaleka ukuchasana novavanyo lwenkungu yetyuwa ngaphezulu kweeyure ezingama-1200 emva kokuba ingekabonakali ibomvu. umhlwa, umhlwa obonakalayo onamandla.
I-3, ukuchasana nokushisa okuphezulu xa kuthelekiswa nomgca we-galvanized wendabuko wefilimu ye-passivation ephezulu kune-70 DEG C i-dehydrated cracking phenomenon, i-Dacromet yokugqoka kwiqondo lokushisa eliphezulu le-500 DEG C isenokugcina ukusebenza okuzinzile, ukuxhathisa kwe-corrosion kuhle kakhulu.
4, akukho embrittlement hydrogen Dacromet ukutyabeka ngaphandle pickling acid kunye nokunyanga kumaqondo obushushu aphezulu, ukusuka kwinkqubo imisela akukho hydrogen embrittlement phenomenon, ilungele iindawo amandla aphezulu kunye nelungu entwasahlobo.
I-5, i-permeability ephezulu, i-adhesionDacromet ngendlela yokudipha unyango, ayithintelwanga yimo ye-workpiece;ukubambelela kakuhle akubonakali nje kuphela kwi-matrix, kunye nezinye iingubo ezongezelelweyo zinokubambisana okuqinileyo.
Changzhou Junhe Technology Stock Co.,Ltd.kukuzibophelela ekuveliseni imichiza emihle, izixhobo ezikhethekileyo kunye nenkqubo yenkonzo yokusombulula inkqubo ibonelela ngamashishini abucala obuchwepheshe obuphezulu.Ukuzibophelela kwi-Dacromet kunye nophando lwe-teknoloji ye-Dacromet, inemizila yokuvelisa i-Dacromet yokuvelisa kunye nezixhobo eziphambili ze-Dacromet, izixhobo zokugqoka i-Dacromet, umatshini wokugqoka i-Dacromet kunye nomgangatho we-Dacromet yokugubungela ulwelo.
