Iposwe kwi 2018-03-21Ukusetyenziswa kwe-dacromet yokwambathisa, uninzi lweenkampani ezisemgangathweni zobushushu bebhanti yesithando somlilo zilawula ubushushu bommandla we-preheat 80 ~ 120℃。 Eyona njongo yokufudumeza kukwenza umphunga ukufuma kwengubo ngaphandle kokubilisa, kwangaxeshanye, ngokuqinisekileyo kukhatshwa. ngenkqubo yemichiza yokunciphisa i-chromium enehexavalent ngotywala.
Indlela yolu kuzimisela ngumxube we-Dacromet B ecocekileyo (i-anhydride ye-chromic enamanzi) kunye ne-polyethylene glycol reductant ngokomlinganiselo.Ingubo yabhaka kwisilayidi seglasi kwaye ishushu kwi-120 ° C imizuzu eyi-15.Amanzi aba ngumphunga kwaye into eseleyo yayiyifilimu eluhlaza emnyama emanzi.
Ukuba isiqwenga sokuvavanya sifudumala ukuya kwimizuzu eyi-120, umbala wengubo uba luhlaza oqaqambileyo, kwaye isambatho siba nzima, kodwa sinokuhlanjwa ngamanzi.Ngokucacileyo, akunakwenzeka ukusebenzisa ukufudumala kwexesha elide kwi-120 ° C ukuze kusebenze i-coating ye-Dacromet.
