Dakeluo rubutun sauti ne da taƙaitawar kalmar Turanci dacromet. Ma'aikatan fannin sukan kira shi Dakeluo ko Dakexiu. A Sin ana kiransa rufin zinc da chromium, sabon nau'in fentin hana lalatawa ne wanda manyan abubuwansa suka haɗa da foda na zinc, foda na aluminum, chromic acid da ruwan da aka cire ions. Kariyarsa ta kasu uku: na farko, shinge — faranti ƙanana na zinc da aluminum da suka hau juna suna hana abubuwa masu lalatawa kamar ruwa da oxygen isa asalin abu, suna samar da keɓewa da kariya; na biyu, passivation — yayin sarrafa Dacromet, chromic acid yana yin hali da foda na zinc, aluminum da asalin abu, ya samar da shimfiɗar passivation mai matuƙar haɗewa da juriyar lalatawa mai kyau; na uku, kariyar cathode — mafi muhimmancin kariyar rufin zinc, aluminum da chromium shi ne kare asalin abu a matsayin cathode, kamar rufin zinc. Idan aka kwatanta da shafa ƙarfe da wutar lantarki na gargajiya, ana iya ɗaukar Dacromet a matsayin 'shafawa mai kare muhalli'. Fa'idodinsa sun haɗa da juriyar lalatawa sosai, rashin saɓewar ƙarfe saboda hydrogen, juriyar zafi mai yawa, kyakkyawan shiga ƙananan wurare, mannewa da sake shafawa masu kyau, rashin gurɓatawa da cutarwa. Amma rashin cutarwar da aka ambata yana nufin cewa yayin samarwa ba a fitar da gas da ruwan sharar da suke buƙatar kula da shara iri uku; ba yana nufin cikakken rashin cutarwa ba. Fentin Dacromet yana ɗauke da wani kaso na chromium, wanda yake da guba da haddasa cutar kansa ga mutane, kuma yana cutar da amfanin gona da ƙananan halittu sosai. Saboda haka, fentin Dacromet marar chromium ya zama buƙatar ci gaban yau da nan gaba. Ta haka ne kawai za a iya ƙara ragewa ko kawar da cutar muhalli da mutane.

Don rage ko cire chromium gwargwadon iyawa tare da kiyaye muhimman kaddarorin shimfiɗar Dacromet, domin rage haɗarinta, ƙwararru sun samar da sabuwar shimfiɗar Dacromet marar chromium. Ana cimma hakan ta wannan tsarin: shimfiɗar tana ƙunshe da foda ta zinc, foda ta aluminum, sinadarin narkarwa, sinadarin taimako da na kafa fim, tare da tin. Kasonta bisa nauyi shi ne zinc 20-30%, aluminum 5-10%, sinadarin narkarwa 20-30%, na taimako 5-10%, na kafa fim 10-10%. Musamman, tana da waɗannan kason nauyi: zinc 20-30%, aluminum 5-10%, diethylene glycol butyl ether 20-30%, n-butanol 5-10%, resin marar asalin halitta 10-20%, tin 5-10%. Sinadarin narkarwa shi ne diethylene glycol butyl ether; na taimako n-butanol ne; na kafa fim resin marar asalin halitta ne. Foda ta zinc tana da siffar ɓawo mai diamitan 5-25 micromita. Foda ta aluminum ma tana da siffar ɓawo mai diamitan 5-25 micromita. Resin ɗin na matakin masana'antu ne.

Idan aka kwatanta da fasahar da ake da ita, wannan sabuwar shimfiɗar Dacromet marar chromium tana da fa'idodi masu zuwa: ingantaccen zanenta ya maye gurbin chromic acid na gargajiya da tin da sinadarin kafa fim, yana kauce wa haɗarin chromium. Tin ba ya yin tsatsa kuma yana jure tasirin waje, tare da ɗan sassauci da ke inganta sarrafa shimfiɗar Dacromet. Haka kuma resin marar asalin halitta sinadari ne mai dacewa da muhalli, mai ƙarancin kuɗi da ƙarin ƙimar yaɗawa.
