E ngotsoe ka 2018-01-08Lisebelisoa tsa ho roala li-zinc flake li phetha karolo ea bohlokoa indastering ea morao-rao, kopo ea ho roala ka zinc flake tlhahiso e tloaelehile haholo, empa lesela la zinc le ke ke la bolokoa mocheso o phahameng, ke hobane'ng?
Hobane mocheso o phahameng o bonolo ho baka botsofali ba tharollo ea ho roala, mocheso oa polokelo oa litharollo tsa ho roala zinki li lokela ho laoloa ho 10 DEG C. Ka nako e ts'oanang tlas'a khanya ea letsatsi, ho roala ho bonolo ho polymerize, ho fetoha esita le ho senya, kahoo. ho molemo ho boloka moriti leseling.Nako ea polokelo ea pente ea coating ea zinki ha e bonolo haholo, hobane mokelikeli o lokiselitsoeng nako e telele, boleng ba pH bo bonolo ho phahama, bo bakoang ke botsofali ba mokelikeli bo neng bo hlakotsoe, liteko li bontša hore ha ho na litšila tsa mokelikeli chromatedacromet ka mor'a ho lokisetsa bonnete. nako ea mocheso oa 20 ° C bakeng sa matsatsi a 30, mocheso oa 30 ° C o sebetsa ka letsatsi la 12, 'me ka nako ea 40 deg.c ka matsatsi a 5 feela.
Litharollo tsa ho roala li-zinc flake li tlameha ho ba teng maemong a mocheso o tlase, mocheso o phahameng o tla etsa hore mokelikeli o koahele ka botsofali.
