Adalemba pa 2015-11-16Ndi kafukufuku wowonjezereka, anthu amazindikira kuti ukadaulo wa dacromet siwobiriwira komanso wopanda ukadaulo wopanda kuipitsidwa, pali zovuta zina.
1. Vuto la kuipitsa: Dacromet yankho la chromic acid ndi lalitali kwambiri, pokonzekera ndikugwiritsa ntchito anthu mosakayikira adzakumana nalo, pogwiritsa ntchito zida ndi zida zidzaipitsidwa, kulowa mufilimu koyambirira. ndondomeko, izo mosalephera ndi evaporation wa nthunzi madzi (kuchokera chromium plating zinachitikira), kotero okonzeka kuchokera njira kupanga ❖ kuyanika ndondomeko kuchita ❖ kuyanika mpweya, madzi ndi olimba zinthu zoopsa umatulutsa zovuta kwambiri, kapena kuteteza chilengedwe zida ndalama ndi lalikulu kwambiri. .Apanso, pamene dzimbiri zokutira zilinso ndi kuwonongeka kwa Dacromet, ma chromium asanu ndi limodzi mufilimu yokutira adzamasulidwa.Hexavalent chromium ku kawopsedwe ka anthu ndi carcinogenicity ndi yamphamvu kwambiri, pakadali pano mayiko ambiri okhala ndi hexavalent chromium ali ndi malire okhwima komanso amaletsa kugwiritsa ntchito.Chifukwa chake, chakhala chotchinga chosagonjetseka ku Dacromet.
2.Kutentha kwakukulu kwa sintering, kugwiritsa ntchito mphamvu zambiri.
3.Kulimba kwapamtunda ndi kukana kuvala sikwabwino, palinso zovuta zolumikizirana ndi galvanic corrosion ndi zitsulo zofananira, zomwe zimakhudza mawonekedwe amtundu wazinthu komanso magwiridwe antchito odana ndi dzimbiri.
