Kuthunyelwe ku 2018-01-08Imishini yokugqoka i-Zinc flake idlala indima ebalulekile embonini yesimanje, isicelo se-zinc flake coating ekukhiqizeni sivame kakhulu, kodwa i-zinc flake ayikwazi ukugcinwa ekushiseni okuphezulu, yingakho?
Ngenxa yokuthi ukushisa okuphezulu kulula ukubangela ukuguga kwesisombululo sokugqoka, izinga lokushisa lokugcina le-zinc flake coating solutions kufanele lilawulwe ku-10 DEG C. Ngesikhathi esifanayo ngaphansi kokukhanya kwelanga, ukugqoka kulula ukwenza i-polymerize, ukushintsha ngisho ne-scrap, ngakho-ke. kungcono ukugcina umthunzi ekukhanyeni.Isikhathi sokugcina se-zinc flake enamathela ngopende akulula kakhulu isikhathi eside, ngoba i-liquid enamathela ilungiselelwe isikhathi eside, inani le-pH likhuphuka kalula, okubangelwa ukuguga kwe-liquid ukuguga, ucwaningo lubonisa ukuthi akukho uketshezi lwe-chromatedacromet ngemuva kokulungiselela ukuba semthethweni. Isikhathi sokushisa esingu-20 DEG C izinsuku ezingu-30, izinga lokushisa elingu-30 DEG C lisebenza ngosuku lwe-12, futhi phakathi nesikhathi esingu-40 deg.c izinsuku ezingu-5 kuphela.
Izixazululo ze-Zinc flake coating kumele zibe khona esimweni sokushisa okuphansi, izinga lokushisa eliphezulu lizokwenza uketshezi lwe-coating ukuguga.
