Phosphating pretreatment line bakeng sa likarolo tsa tšepe kapa likarolo tse cheselitsoeng

OURS COATING e fana ka lisebelisoa tsa morao-rao tsa lisebelisoa tsa phosphating bakeng sa likarolo tsa tšepe kapa li-welds tse sebelisoang lits'ebetsong tse fapaneng.

Hore na o hloka ho nchafatsa mela ea khale, kapa o hloka ho reka e ncha, esita le ho buisana le mathata afe kapa afe a tekheniki, ikopanye le rona feela, re tla u fa tharollo ea ho emisa hang.

Mefuta ea Mela ea Phosphate

● phosphate ea tšepe

Iron phosphate ke eona e sebelisoang haholo pele bakeng sa ho roala phofo hobane e ka sebelisoa hoo e batlang e le ntho efe kapa efe, 'me e na le lihlahisoa kapa li-sludge tse baballang tikoloho. Mokhoa ona o atisa ho sebelisoa ka thepa ea tšepe.

● Zinc Phosphate

Zinc phosphate ke sekoaelo se seng sa tšepe, sa kristale se khomarelang thepa haholo. Ke habohlokoa ho hlokomela, zinki phosphate e hlahisoa ke tharollo ka boeona, eseng ho tloha karolong e ka holimo e kang seaparo sa phosphate ea tšepe. Likristale tsa zinc phosphate li qala ho ikemela libakeng tsa anodic holim'a karolo e ka holimo ebe li emisa ho theha ha karolo e ka holimo e chesoa, ke hore. ba otla kristale e 'ngoe. Ho fapana le phosphate ea tšepe, phosphate ea zinki ha e khone ho hloekisa le ho apara ka nako e le 'ngoe: ka hona, ho hlatsoa li-stage tse' nè, ho hlatsoa, zinki phosphate, ho hlatsoa ke mokhoa o tloaelehileng. Le hoja zinc phosphating e fana ka thepa e ntlafetseng ea ho khomarela, ho roala hantle libakeng tse thata le ho thibela kutu, mokhoa ona o na le litšenyehelo tse phahameng tsa ts'ebetso, o sebelisa litšepe tse boima, 'me o ka hlahisa litšila tse ngata, tseo ho seng le e 'ngoe ea tsona e sa silafalitseng tikoloho bakeng sa merero ea ho lahla. Zinc phosphate hangata e sebelisoa linthong tsa tšepe tse entsoeng ka masenke.

● Chromium phosphate

Chromium phosphate e sebelisoa hangata bakeng sa likarolo tse thehiloeng ho alloy ea aluminium. Le ha ts'ebetso ena e sebetsa, joalo ka zinc phosphate, e sebelisa litšepe tse boima tse hlokang ho khutlisoa bakeng sa ho lahla tikoloho.

●Litaolo tsa Ts'ebetso ea Phosphate

Ho laola ts'ebetso ea phosphating ke habohlokoa ho finyella liphahlo tse tsitsitseng tse qetellang li etsa hore ho be le mokhoa o tsitsitseng oa ho roala. Litaolo tsa bohlokoa ka ho fetisisa tsa ts'ebetso ea ho roala phosphate phetolo ke:

Nako - ha nako e telele ea ho kopana le nako e eketsehileng ea ho itšoara ka lik'hemik'hale, ts'ebetso e tlameha ho ba nako e lekaneng ho lumella k'hemistri ho etsa seaparo se tšoanang.

Mocheso - lik'hemik'hale hangata li ba mabifi ho feta mocheso o phahameng

Concentration le pH - ha acid e le ho feta ka har'a mahloriso e potlakisa ts'ebetso ea ho roala 'me e ka fella ka boima bo boima ba ho roala.
