2. Dacromet Coating ke eng?

Dacromet ke mokhoa oa ho roala li-zinc-aluminium flake o ntlafalitsoeng e le mokhoa o tsoetseng pele ho fapana le electroplating e tloaelehileng. Ho roala ho na le li-flakes tsa zinki tse holimo le li-flakes tsa aluminium ka har'a setlamo sa inorganic. Ha e sebelisoa ho liboutu tse nang le mahlakore a mabeli 'me e phekotsoe hoo e ka bang 300 ° C, e theha mokoallo o teteaneng, o nang le mekhahlelo e mengata e fanang ka mokhoa o tsotehang. anti-rust le anti-corrosion tshebetso.

Litšobotsi tsa bohlokoa tsa ho roala ha Dacromet holim'a liboutu:

• Filimi e nyane: Ka tloaelo ke 4-12 μm feela (hangata 6-8 μm), e bolokang thupa ea geometry le ho lekana ka liboutu tse nepahetseng tsa hexagonal.
• Tšitiso + tšireletso ea sehlabelo: Zinc e entsoeng ka laminated le li-flakes tsa aluminium li thibela mongobo / oksijene 'me li fana ka tšireletso ea galvanic (sehlabelo) ea substrate ea tšepe.
• Tšebeliso e tšoanang: Ts'ebeliso ea Dip-spin kapa spray e netefatsa tšireletso e ntle ho lijeometri tse rarahaneng, ho kenyeletsoa likhoele tse tebileng le hlooho e nang le mahlakore a mabeli.

Khanyetso e Ikhethang ea Corrosion & Anti-Rust Performance

Monyetla o ka sehloohong oa li-bolts tsa hexagonal tse koahetsoeng ka Dacromet o hlahelletse khanyetso ea kutu le nako e telele anti-rust bokgoni. Leha a na le masela a manyane a 4-8 μm feela, liboutu tsena li lula li mamella liteko tse sa nkeng lehlakore tsa letsoai (ASTM B117 / ISO 9227) ka lihora tse fetang 1,000 - 'me hangata 1,200 ho feta lihora tse 2,000 - ntle le mafome a khubelu. Sena hangata se betere ka makhetlo a 7-10 ho feta mokhoa o tloaelehileng oa motlakase (lihora tse 100-300) 'me o qothisana lehlokoa le kapa o phahame ho feta lithako tse ngata tse teteaneng tsa hot-dip galvanizing.

Sebopeho sa li-multi-layer zinc-aluminium flake se thibela mongobo, oksijene le chloride. Leha e senyehile sebakeng sa heno, ketso ea sehlabelo ea zinki e ntse e tsoela pele ho sireletsa bolt substrate, e ntlafatsa ka kakaretso. thibelo ea mafome. Sena se etsa hore liboutu tsa Dacromet tse hexagonal li be ntle bakeng sa libaka tse lebopong la leoatle, tsa leoatle, likoloi tse ka tlas'a lefatše le tikoloho ea indasteri.

Kotsi ea Zero Hydrogen Embrittlement

Monyetla oa bohlokoa bakeng sa liboutu tse matla a phahameng a hexagonal ke ho ba sieo ho felletseng ha kotsi ea hydrogen embrittlement. Electroplating e kenya haedrojene ea athomo ka har'a tšepe, e ka bakang ho lieha ho robeha ha brittle sehlopheng sa 10.9, 12.9, le liboutu tsa sebopeho tse kang ASTM A490. Dacromet ha e na electrolytic 'me e qoba ho bokella acid e mabifi, kahoo ha ho na hydrogen e hlahisoang. Dacromet e matla e phahameng liboutu ka hona ha ho hloke ho baka ka mor'a plating 'me ho fana ka ts'epo e phahameng ka har'a manonyeletso a bohlokoa ka ho fetisisa. Li-OEM tse ngata tsa likoloi li hlakisa Dacromet kapa liaparo tse lekanang tsa zinc-flake ka lebaka lena.

Ho hanyetsa Mocheso o Phahameng

Liaparo tsa Dacromet li boloka botšepehi le anti-corrosion tshebetso ka mocheso o tswelang pele ho fihla ho 300°C. Electroplating e tloaelehileng ea zinki e theoha ka holimo ho 100-120 ° C, ha hot-dip galvanizing e na le meeli e tlaase e ka holimo. Botsitso bona ba mocheso bo lumellana le liboutu tsa Dacromet tse hexagonal bakeng sa likarolo tsa enjene, lisebelisoa tsa ho felloa ke matla, lionto tsa indasteri, le lisebelisoa tsa tlhahiso ea matla moo matla a ho koala le nako e telele. thibelo ea mafome lia hlokahala.

4. Papiso ea Ts'ebetso

Tafole e ka tlase e bapisa Dacromet le likhoele tse tloaelehileng tse sebelisoang ho liboutu tse hexagonal:

5. Likopo tse Tloaelehileng

Ke leboha ba phahameng anti-corrosion, anti-rust, ho hanyetsa mocheso, le ho lokoloha ho tsoa ho hydrogen embrittlement, Dacromet hexagonal bolts li sebelisoa haholo ho:

5.1 Indasteri ea Likoloi

Likarolo tsa chassis, litsamaiso tse emisitsoeng, likopano tsa mariki, lisebelisoa tsa enjine, le lits'ebetso tsa underbody. Tsena liboutu e tlameha ho hanela letsoai la tseleng, mongobo, ho palama libaesekele tse futhumetseng, le ho thothomela. Ho ba sieo ha hydrogen embrittlement ke habohlokoa bakeng sa boemo bo phahameng ba matla a 10.9 le li-fasteners tsa 12.9 manonyeletsong a amanang le polokeho.

5.2 Kaho, Meaho le Boenjiniere bo boima

Marokho, meaho ea litšepe, litora tsa phetiso, li-turbine tsa moea le metjhini e boima li hloka nako e telele khanyetso ea kutu. Dacromet hexagonal bolts fana ka tse tšepahalang thibelo ea mafome ka ntle le libakeng tse lebopong la leoatle ha ho ntse ho bolokoa ho lekana hantle le ts'ebetso e phahameng ea tsitsipano.

5.3 Tikoloho ea Maoatleng, Maoatleng le Lik'hemik'hale

Sefafatsi sa letsoai, mongobo o tsoelang pele, le ho pepesehela lik'hemik'hale li hlokoa haholo anti-corrosion tshebetso. Li-bolts tsa hexagonal tse koahetsoeng ka Dacromet li sebetsa thepa ea sekepe sa likepe, lipolanete tse lebōpong la leoatle, lisebelisoa tsa boema-kepe, le li-fasteners tsa limela moo liphahlo tse tloaelehileng tsa zinki li hlōlehang ka potlako.

5.4 Litšebeliso tse ling tsa indasteri
