Iposwe kwi 2018-01-08Izixhobo zokugquma i-zinc zidlala indima ebalulekileyo kumashishini anamhlanje, isicelo sokufakela i-zinc flake kwimveliso sixhaphake kakhulu, kodwa i-zinc flake ayikwazi ukugcinwa kwiqondo lokushisa eliphezulu, kutheni?
Ngenxa yokuba ukushisa okuphezulu kulula ukubangela ukuguga kwesisombululo sokugubungela, ukushisa kokugcinwa kwe-zinc flake i-coating solutions kufuneka ilawulwe kwi-10 DEG C. Ngexesha elifanayo phantsi kokukhanya kwelanga, ukugubungela kulula ukupholisa, ukutshintsha kunye nokulahla, ngoko ke. kungcono ukugcina umthunzi ekukhanyeni.Ixesha lokugcinwa kwepeyinti ye-zinc flake yokwambatha ayilula kakhulu ixesha elide, ngenxa yokuba ulwelo olulungiselelwe ixesha elide, ixabiso le-pH lilula ukunyuka, libangelwa ukuguga kolwelo olulahliwe, imifuniselo ibonisa ukuba akukho nkunkuma ye-chromatedacromet emva kokulungiselela ukuqinisekiswa. ixesha lobushushu be-20 DEG C kwiintsuku ze-30, ukushisa kwe-30 DEG C kuvumelekile kwi-12 imini, kwaye ngaphakathi kwexesha le-40 deg.c iintsuku ezi-5 kuphela.
Izisombululo ze-zinc flake zokwaleka kufuneka zibekho kwimeko yobushushu obuphantsi, ubushushu obuphezulu buya kwenza ukuba ulwelo lube yinto yokuguga.
