Tshaj tawm rau 2018-01-08Zinc flake txheej khoom ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no, zinc flake txheej daim ntawv thov hauv kev tsim khoom yog ntau heev, tab sis zinc flake tsis tuaj yeem khaws cia ntawm qhov kub thiab txias, uas yog vim li cas?
Vim tias qhov kub thiab txias yog ib qho yooj yim ua rau kev laus ntawm txheej txheej, cia kub ntawm zinc flake txheej daws yuav tsum tau tswj ntawm 10 DEG C. Nyob rau tib lub sij hawm nyob rau hauv lub hnub ci, lub txheej yog yooj yim rau polymerize, hloov thiab txawm seem, yog li ntawd. Nws yog qhov zoo tshaj kom khaws qhov ntxoov ntxoo hauv qhov kaj.Lub sij hawm cia ntawm zinc flake txheej xim tsis yooj yim ntev, vim hais tias cov kua txheej npaj lub sij hawm ntev dua, tus nqi pH yog yooj yim dua, tshwm sim los ntawm cov kua txheej txheej laus tau muab pov tseg, kev sim qhia tias tsis muaj cov kua khib nyiab chromatedacromet tom qab npaj qhov siv tau. Lub sij hawm ntawm qhov kub ntawm 20 ° C rau 30 hnub, qhov kub ntawm 30 ° C yog siv tau rau 12 hnub, thiab nyob rau hauv ib lub sij hawm ntawm 40 deg.c rau 5 hnub xwb.
Zinc flake txheej kev daws teeb meem yuav tsum muaj nyob rau hauv qhov xwm txheej ntawm qhov kub thiab txias, qhov kub thiab txias yuav ua rau cov kua txheej txheej aging tshwm sim.
