Yakatumirwa pa 2016-12-22Zvinonyatsozivikanwa kuti Dacromet inorasika aqueous mhinduro inosanganisira zinc flake, aluminium flake uye additives.Zvishandiso mushure mekunyura uye kupfapfaidza, kurapa 20min pa80 ℃ muchoto chekupisa, 30min pa300 ℃ pakurapa choto.Gadzira hexavalent chromium yaive adipic doro uye organic kuderedzwa kuita fluid yedacromet coating hainyungudika mumvura.
Zvinofanira kucherechedzwa kuti kudzikiswa kwehexavalent chromium kuita trivalent chromium uye trivalent chromium oxidation kuita hexavalent chromium inzira inodzokororwa.Naizvozvo, mune iyo sintered workpiece, trivalent chromium icharamba ichiitwa oxidized kune hexavalent chromium, uye hexavalent chromium icarcinogen, saka kubata kunounza kukuvadza kuhutano.Naizvozvo, iyo yechinyakare chromium-ine coating mhinduro haina zvachose zero emissions, chero kuvepo kweiyo hexavalent chromium, ichave nekumwe kukanganisa kune nharaunda uye vanhu, saka, kufarirwa kwechrome yemahara Dacromet kwakakosha.
Nekuedza kwenyika kuchengetedza kwezvakatipoteredza kuri kuramba kuchisimba, vagadziri vezvikamu zvemotokari vanowedzera vanoda chrome yemahara dacromet yakavharwa zvikamu.Uye kunyange yakagadziridzwa chrome yemahara dacromet coating tekinoroji zviyero.Zvakadai seVolkswagen GMW3359, GM7111M nezvimwe.
Chrome yemahara Dacromet inonyanya kutsvaga zvimwe zvinhu pachinzvimbo chechromic acid passivation uye bonding.Chrome yemahara Dacromet coating inonyanya kushandisa organic silicon, inorganic silicon, molybdate, tungstate, phosphate sebinder, kushandiswa kwakafanana kwescaly zinc / aluminium flake sechinhu chikuru chekuzadza, uye kuburikidza nenhevedzano yechisimbiso Post-kurapa, kuti uwane iyo yakafanana yakanakisa. corrosion resistance ine chromium-ine Dacromet coating.
Chrome yemahara Dacromet tekinoroji haingove nemukana wekromium-dacromet tekinoroji, asiwo kubva pakugadzirira pendi, kupfekedza, firimu, kuzviputira pachayo haina zvachose hexavalent chromium, iyo yechokwadi pfungwa yekuzadzikiswa kwegirinhi isina chepfu isingakuvadzi.Kubva pakuona kwezvakatipoteredza, muchikamu chepasi rose chechrome yemahara Dacromet pachinzvimbo chechrome dacromet general direction haizoshanduke, ichaunza kutenderera kutsva kweanti-corrosion tekinoroji munda wekuchinja kwezvakatipoteredza.
