Dacromet Hex Bolts: Khanyetso e Phahameng ea Corrosion le Ts'ebetso e Tšoarellang 

3. The Dacromet Coating Process bakeng sa Hex Bolts

Tlhahiso ea Liboutu tsa hex tsa Dacromet e latela ts'ebetso e laoloang ka hloko e seng ea electrolytic e netefatsang tšireletso e ts'oanang le ho felisa likotsi tsa hydrogen embrittlement:

1.Ho lokisa holim'a metsi: Hex liboutuli hloekisoa ka botlalo ho tlosa oli, mafura, sekala le litšila ho netefatsa ho khomarela hantle Dacromet

2. Tšebeliso ea ho roala: E hloekisitsoe liboutuli qoelisoa ka har'a seretse se thehiloeng metsing sa zinki le li-flakes tsa aluminium tse nang le li-binders. Dip-spin kapa mekhoa ea ho fafatsa e netefatsa hore ho na le ho roala holim'a likarolo tsohle tsa hexagonal liboutu, ho kenyelletsa likhoele le likheo.

3. Ho folisa: Ka mor'a hore slurry e feteletseng e tlosoe, e koahetsoe liboutuli behoa ka mocheso oa hoo e ka bang 300 ° C. Inorganic binder e tiisa le ho kopanya li-flakes tsa zinc-aluminium le tšepe, ho etsa tšireletso. Dacromet

4.Tlhahlobo: E felile Liboutu tsa Dacrometli hlahlojoa bakeng sa botenya ba ho roala, ponahalo, ho khomarela, le khanyetso ea kutu. Li-topcoats tse ikhethileng li ka ntlafatsa khanya kapa 'mala.

Hobane the Dacromet ts'ebetso e kenyelletsa ho se be le acid e pickling kapa deposition electrolytic, ha ho na kotsi ea hydrogen embrittlement. Sena se etsahala Dacromet haholo-holo e loketseng hex e matla haholo liboutu ea limaraka tsa 8,8, 10,9, le 12,9.

4. Melemo ea Bohlokoa ea Dacromet Hex Bolts

Liboutu tsa hex tsa Dacromet fana ka motsoako o ikhethang oa melemo ea ts'ebetso e ba khethollang ho tse tloaelehileng tsa galvanized kapa plated liboutu:

4.1 Ho Hanyetsa ho Corrosion ho Hlollang

Tšobotsi ea bohlokoa ka ho fetisisa ea Dacromet (Darcomet) ke e ikhethang anti-corrosion bokgoni. Standard Liboutu tse koahetsoeng ka Dacromet ka tloaelo ho fihlela lihora tse fetang 1,000 tsa ho hanyetsa ho fafatsa letsoai ntle le mafome a khubelu; limaraka tse sebetsang hantle haholo li ka feta lihora tse 2,000. Ha ho bapisoa le electro-galvanizing ea setso, Liboutu tsa Dacromet fana ka makhetlo a 7 ho isa ho a 10 ho feta tshireletso ya kutu. Le litekong tsa cyclic corrosion le tikolohong ea sulfur dioxide, Liboutu tsa hex tsa Dacromet boloka botshepehi bo babatsehang.

4.2 Ha ho na Hydrogen Embrittlement

Matla a phahameng liboutu ba kotsing ea ho embrittlement ea haedrojene ha e sebetsoa ka mokhoa o tloaelehileng oa electroplating. The Dacromet ts'ebetso e qoba ka ho feletseng kotsi ena hobane ha e na electrolytic. Ka lebaka leo, Liboutu tsa hex tsa Dacromet tsa limaraka tse phahameng li lula li bolokehile 'me li ka tšeptjoa ha li le tlas'a mojaro, li etsa hore e be tse loketseng bakeng sa lisebelisoa tsa bohlokoa tsa sebopeho le likoloi.

4.3 Ho Hanyetsa Mocheso ka Bokhabane

Dacromet masela a lula a tsitsitse mocheso ho fihlela ho 300 ° C kapa ho feta. Liaparo tsa setso tsa zinki li qala ho senya kapa ho lahleheloa khanyetso ea kutu ka holimo ho 70–100°C ’me e ka ’na ea hlōleha ho 200–300°C. Ho fapana le hoo, Liboutu tse koahetsoeng ka Dacromet boloka ponahalo le ts'ireletso ea ts'ireletso tlas'a maemo a nako e telele a mocheso o phahameng-a bohlokoa likarolong tsa enjene, litsamaiso tsa mosi le lisebelisoa tsa indasteri.

4.4 Ho Kena ho Phahameng le Filimi e Nyenyane

Tšebeliso ea dip-spin ea Dacromet e etsa bonnete ba hore ho roala ho kenella ka hare ho botebo, likhoele le masoba a foufetseng a hex liboutu. Ka botenya bo tloaelehileng ba 6-10 μm feela, the Dacromet filimi ha e fetole haholo litekanyo tsa khoele, ho lumella Liboutu tsa hex tsa Dacromet ho sebedisoa ka makotomane a tlwaelehileng. Sena se phahameng permeability e fana ka ho feletseng anti-corrosion tšireletso esita le ho li-geometri tse rarahaneng.

4.5 Ho khomarela hantle le ho Recoatability

Dacromet liphahlo li khomarela ka matla ho substrate ea tšepe 'me li amohela li-topcoats tse eketsehileng tsa organic kapa lipente hantle haholo. Ho feto-fetoha ha maemo ho ts'ehetsa li-coefficients tsa likhohlano tse ikhethileng le likhoutu tsa mebala bakeng sa letoto le fapaneng la liboutu.

5. Likopo tsa Dacromet Hex Bolts

Ke leboha mookameli oa bona khanyetso ea kutu le ho tšepahala, Liboutu tsa hex tsa Dacromet li hlahisoa ka bongata liindasteri tse ngata:

Likoloi le lipalangoang: Chassis, fanyeha, 'mele le enjene liboutue hlokang nako e telele anti-corrosion tshebetso tlas'a letsoai la litsela le ho pepesehela boemo ba leholimo.

Kaho le meralo: Sebopeho liboutubakeng sa marokho, litora, lithapo tsa phetiso, le meaho e lebopong la leoatle moo Dacromet tshireletso e lelefatsa bophelo ba tshebeletso haholo.

Marine le offshore: Hex liboutue sebelisoang likepeng, li-platform tsa offshore, le thepa ea boema-kepe e rua molemo ho tsoa ho khanyetso e ikhethang ea ho fafatsa letsoai ea Dacromet.

Matla a ka nchafatsoang: Litora tsa turbine tsa moea le lisebelisoa tsa ho holisa letsatsi li sebetsa Liboutu tse koahetsoeng ka Dacrometbakeng sa kantle e tšepahalang tshireletso ya kutu.

Mechini ea indasteri: Matla a phahameng liboutulifemeng tsa lik'hemik'hale, tlhahiso ea matla, le mechine e boima e itšetlehile ka Dacromet bakeng sa nako e telele maemong a senyang.
