Iposwe kwi 2019-03-11Izixhobo zeDacromet zidlala indima ebalulekileyo kumashishini anamhlanje.Iingubo zeDacromet nazo zixhaphake kakhulu kwimveliso, kodwa iingubo zeDacromet azikwazi ukugcinwa kumaqondo aphezulu.Ngoba?
Isizathu kukuba kukho uthotho lweenzuzo kwitekhnoloji yeDacromet enokuthi i-plating yemveli ayinakuhambelana, etyhalelwa ngokukhawuleza kwimarike yamazwe ngamazwe.Emva kweminyaka engaphezu kwe-20 yophuhliso oluqhubekayo kunye nokuphuculwa, iteknoloji ye-Dacromet ngoku yenze inkqubo yonyango epheleleyo, esetyenziswa ngokubanzi kunyango oluchasene ne-corrosion yezingxenye zetsimbi.Le nkampani yaseka i-Nippon.Darro.shamrock (NDS) ngo-1973 kunye neJapan Oil & Fats Co., Ltd., kwaye yaseka i-DACKAL eYurophu naseFransi ngo-1976. Bahlula imarike yehlabathi kwiimarike ezine ezinkulu: i-Asia Pacific, iYurophu, Afrika kunye naseMelika.Inoxanduva lommandla omnye kwaye ifuna imidla efanayo kwihlabathi jikelele.
Ngenxa yokuba ubushushu obuphezulu, okukhona ukuguga kolwelo lokugquma, ubushushu bokugcinwa kolwelo lwe-Dacromet yokwambathisa kukhethwa ukulawulwa ngaphantsi kwe-10 °C.Ngelo xesha, phantsi kokukhanya kwelanga, i-coating liquid ilula ukupholisa, i-metamorphose, kwaye ikhutshwe, ngoko kukulungele ukuyigcina kwindawo epholileyo.Ixesha lokugcinwa kwe-Dacromet yokugubungela ulwelo alude kakhulu, kuba ixesha elide ulwelo olugciniweyo olugciniweyo, ukuphakama kwexabiso le-pH kuya kuba, okuya kubangela ukuba i-coating liquid iguge kwaye ilahlwe.Ezinye iimvavanyo zibonise ukuba inkunkuma emva kokulungiswa kwe-chromium-free Dacromet, ulwelo lusebenza iintsuku ezingama-30 kwi-20 ° C, iintsuku ezili-12 kwi-30 ° C, kunye neentsuku ezi-5 kuphela kwi-40 ° C.
Ngoko ke, i-Dacromet yokugubungela i-liquid kufuneka ibe khona phantsi kweemeko eziphantsi zokushisa, okanye ukushisa okuphezulu kuya kubangela ukuba i-coating liquid iguge.
