Qhov no 60 degree -80 degree zinc phosphating tus neeg sawv cev yog qhov nruab nrab-kub, qis-slag zinc-based phosphating tov. Cov tshuaj phosphating yog tsim los ntawm cov khoom uas muaj cov ntsiab lus hauv qab no: phosphoric acid 100 ~ 200g / L, nitric acid 30 ~ 50g / L, zinc oxide 30 ~ 50g / L, Manganese carbonate 40 ~ 60g / L, nickel nitrate 3 ~ 5g /L, sodium sulfosalicylate 3 ~ 5g / L, tartaric acid 1 ~ 2g / L.
Qhov no 60 degree -80 degree zinc phosphating tus neeg saib xyuas tswj cov kua qaub piv ntawm cov tshuaj kom PO4 3- thiab HPO4 2- nyob rau hauv cov tshuaj precipitate qeeb. Qhov thib ob yog siv cov tshuaj complexing tsim nyog kom muaj nyob rau hauv daim ntawv ntawm complexes xws li Fe2+, Zn2+, Mn2+ thiab lwm yam hlau ions uas tsim thaum lub sij hawm phosphating txheej txheem, kom lub concentration ntawm Fe2+, Zn2+, Mn2+ hauv cov tshuaj txo, yog li txo cov sediment.
Cov txheej txheem nruab nrab-kub zinc-raws li phosphating tov yuav tsim ib tug loj npaum li cas ntawm phosphorus slag thaum lub sij hawm phosphating txheej txheem. Yog tias cov phosphorus slag tsis tuaj yeem raug tshem tawm hauv lub sijhawm, qhov sib xyaw ntawm Fe2+ hauv lub tank phosphorus yuav siab heev, cuam tshuam rau cov nyhuv phosphorus. Yog li ntawd, slag yuav tsum tau tawg txhua hnub thaum siv, uas ua rau kom muaj zog siv zog. Ntawm qhov tod tes, cov phosphorus slags muaj ntau cov txiaj ntsig Zn2+, PO4 3-, thiab HPO4 2- ions. Cov tshuaj phosphating siv ntau heev thiab yuav tsum tau rov ua dua txhua hnub. Txhawm rau txo qis kev siv zog thiab txo kev noj cov tshuaj phosphating, cov tshuaj qis-slag zinc phosphating ntawm cov khoom no yog qhov tseem ceeb heev.
Cov khoom no yooj yim rau kev khiav lag luam thiab siv tau yooj yim: phosphating zaj duab xis muaj cov nyhuv zoo thiab hnyav txog 2-3G / square meter; nws muaj kev nqus tsawg, siv cov khoom siv tsawg thiab nag lossis daus tsawg; nws lub zog tiv thaiv xeb yog muaj zog dua li cov kua zinc-manganese phosphating zoo tib yam.
Kev kho mob ua ntej phosphating teeb meem: roj, xeb thiab lwm yam khoom siv sab nraud yuav tsum raug tshem tawm, txwv tsis pub qhov zoo ntawm cov phosphating zaj duab xis yuav raug cuam tshuam; Kev tshem tawm xeb tuaj yeem ua tau los ntawm kev siv hydrochloric acid lossis sulfuric acid; kev xaiv ntawm degreasing tus neeg sawv cev kuj tseem ceeb heev.
