1. Selelekela ho Dacromet Hex Bolts

Li-bolts tsa hexagon tsa Dacromet li emela sehlopha sa li-fasteners tse sebetsang hantle tse etselitsoeng ho hanyetsa kutu e ikhethang le thibelo ea nako e telele ea mafome. Liboutu tsena li kopanya ts'epahalo ea mochini oa liboutu tse tloaelehileng tsa li-hexagonal tse nang le coating e tsoetseng pele ea zinc-aluminium flake e tsejoang ka hore ke Dacromet (eo hape e bitsoang Dacro kapa zinc-flake coating). Sephetho ke boutu e fanang ka ts'ebetso e ntle ea anti-corrosion libakeng tse thata ha e ntse e boloka jometri e nepahetseng ea likhoele le matla a phahameng a tsitsipano.

Ho fapana le liboutu tse tloaelehileng tsa galvanized electro-galvanized kapa hot-dip galvanized, Dacromet hexagon bolts li sebelisa mokhoa oa ho roala o se nang motlakase. Sena se felisa kotsi ea hydrogen embrittlement-monyetla oa bohlokoa bakeng sa liboutu tse matla haholo tsa limaraka tsa 8.8, 10.9 le 12.9. Filimi e tšesaane, e ts'oanang ea Dacromet (ka tloaelo 4-12 μm) e fana ka khanyetso e phahameng ea letsoai-spray, ho hanyetsa mocheso, le ho tšoarella ka kakaretso ho thibela mafome, ho etsa hore liboutu tsena e be khetho e khethiloeng ho likoloi, kaho, matla a moea, lisebelisoa tsa metsing le tsa indasteri.

2. Dacromet Coating ke Eng?

Dacromet ke thekenoloji ea metsi, e thehiloeng holim'a metsi e entsoeng ka tšepe e entsoeng ka li-flakes tse ntle haholo tsa zinki, li-aluminium flakes le li-binders tse thehiloeng ho chromium. Ha li sebelisoa boutung ea hexagon 'me li folisoa ka mocheso o phahameng (hoo e ka bang 300 ° C), li-flakes li ikamahanya le likarolo tse ngata tse holimo, li etsa mokoallo o teteaneng, oa tšepe oa silevera-grey. Sebopeho sena sa mekhahlelo e mengata se etsa hore ho be le tšitiso ea 'mele khahlanong le mongobo le li-electrolyte le mokhoa oa sehlabelo oa ho itšireletsa oa anodic o hanyetsanang le ho thehoa ha mafome.

Ho roala ho Dacromet hexagon bolt ho fana ka tšireletso e habeli: li-zinc flakes li sebetsa joalo ka anode ea sehlabelo, li senya ka mokhoa o khethehileng ho sireletsa karoloana ea tšepe, ha li-flakes tsa aluminium le matrix a inorganic li matlafatsa thepa ea litšitiso le ho ntlafatsa ho hanyetsa ha kutu ka kakaretso. Hobane ts'ebetso ha e na electrolytic, ha ho na hydrogen e kenngoa ka har'a lesela la tšepe, e bolokang botšepehi bo feletseng ba mechine ea liboutu tse matla haholo.

3. Mokhoa oa ho roala oa Dacromet bakeng sa Hexagon Bolts

Tlhahiso ea "Dacromet hexagon bolt" e tšepahalang e latela tatellano e laoloang ka hloko e etselitsoeng ho eketsa ts'ebetso ea ho khomarela, ho ts'oana le ho thibela kutu:

1. Tokiso ea Sefahleho: Bolt e hloekisoa ka ho feletseng le ho senyeha ha mechine kapa alkaline. Acid pickling e qojoa ka boomo ho thibela ho kenngoa ha haedrojene ho ka lebisang ho embrittlement ea liboutu tse matla haholo.

2. Kopo ea ho Koala: Liboutu tse hloekisitsoeng tsa hexagon li qoelisoa ka hare, li fafatsoa ka tsona, kapa li qoelisoa ka har'a metsi a Dacromet slurry e nang le zinki le li-flakes tsa aluminium. Dip-spin ke mokhoa o atileng haholo oa indasteri oa ho lokisa liboutu ka bongata.

3. Ho phekola / Sintering: Liboutu tse koahetsoeng li behoa ka mocheso o ka bang 300 ° C. Nakong ea ho phekola, sekontiri se arabelang 'me li-metallic flakes li etsa filimi e sa khaotseng, e khomarelang ka thata.

4.Tlhahlobo ea Boleng: Li-bolts tsa hexagon tse felileng tsa Dacromet li hlahlojoa bakeng sa botenya ba ho roala, ho khomarela, ponahalo, le ts'ebetso ea ho fafatsa letsoai ho netefatsa tšireletso e tsitsitseng e khahlanong le mafome.

4. Papiso ea Ts'ebetso ea Li-Anti-Corrosion Coatings

Tafole e latelang e akaretsa liphapang tsa bohlokoa lipakeng tsa liboutu tsa hexagon tsa Dacromet le liboutu tse phethiloeng ka mekhoa ea setso e khahlanong le mafome:

Thepa	Dacromet	Electro-Galvanizing	Hot-Dip Galvanizing
Botenya ba ho roala	4–12 μm	5–15 μm	40-85 μm
Salt Spray (ha ho na mafome a khubelu)	600–1,200+ h	100–300 h	500–800 h
Kotsi ea Hydrogen Embrittlement	Ha ho letho	E phahameng (e hloka ho baka)	Tlase–Mahareng
Ho hanyetsa Mocheso	Ho fihlela ho 300 ° C	≤ 100–120 °C	≤200 °C
Thread Fit Impact	Manate a fokolang / a tloaelehileng a lokile	Nyenyane	E bohlokoa (e ka hloka ho feta)
Boemo ba Tikoloho	Tšilafalo e thehiloeng metsing, e tlaase	Tlhokomelo ea metsi a litšila e hlokahalang	Zinc slag / metsi a litšila

5. Lisebelisoa tse Tloaelehileng tsa Dacromet Hexagon Bolts

Ka lebaka la khanyetso ea tsona e hlahelletseng ea kutu, tlhaho e se nang hydrogen-embrittlement, le ho nepahala ha sebopeho, liboutu tsa hexagon tsa Dacromet li hlalositsoe haholo makaleng a hlokang matla.

Likoloi tsa likoloi le tsa khoebo: Likarolo tsa enjene, chassis, suspension, le li-fasteners tse ka tlase ho 'mele tse tlamehang ho hanela letsoai la tseleng le mongobo.
Matla a moea le matla a ka nchafatsoang: Litora, li-nacelle, le liboutu tsa motheo tse pepeselitsoeng maemo a leholimo a lebopong la leoatle kapa lebopong la leoatle.
Kaho le meralo: Lihokelo tsa meralo, marokho le tšepe ea kantle e hlokang ts'ebetso ea nako e telele e thibelang mafome.
Marine le offshore: Thepa le liboutu tsa meralo li kentsoe moeeng o sa khaotseng oa letsoai.
Mechini ea indasteri le lisebelisoa tse boima: Manonyeletso a matla a phahameng a liboutu libakeng tseo ho ts'eptjoang ha mochini le ts'ireletso ea kutu li bohlokoa.

6. Litlhaloso tsa Tekheniki le Lintlha tsa Ts'ebetso

Matšoao a tloaelehileng a ts'ebetso bakeng sa liboutu tsa hexagon tse koahetsoeng ka Dacromet li akaretsoa ka tlase. Litekanyetso tse nepahetseng li itšetlehile ka boemo ba ho roala (mohlala, Dacromet 320 kapa 500) le mekhoa ea ho sebetsa.

7. Qetello

Liboutu tsa hexagon tsa Dacromet li fana ka tharollo ea sejoale-joale, e sebetsang hantle haholo bakeng sa lits'ebetso tse hlokang matla a phahameng a mochini le ho hanyetsa ho hoholo ha nako e telele. Ka ho kopanya letlapa le tšesaane, le se nang electrolytic zinc-aluminium flake le geometry e nepahetseng ea hexagonal, liboutu tsena li felisa likotsi tsa ho emisoa ke hydrogen ha li ntse li fana ka khanyetso ea spray-spray ho feta hole e tloaelehileng ea electro-galvanizing. Ho hanyetsa mocheso o motle, ho tsamaellana le likhoele, le botsoalle ba tikoloho le tsona li ntlafatsa boleng ba tsona likarolong tsohle tsa makoloi, matla, kaho le indasteri.

Ha ho hlakisoa li-fasteners bakeng sa tikoloho ea litšebeletso tse senyang, baenjiniere le bareki ba ntse ba fetohela ho liboutu tsa hexagon tse koahetsoeng ka Dacromet e le khetho e tšepahalang, e khahlanong le mafome e sireletsang manonyeletso a bohlokoa ka lilemo tse mashome. Taolo e nepahetseng ea ts'ebetso le netefatso ea boleng e netefatsa hore bolt e 'ngoe le e' ngoe e fana ka ts'ebetso e felletseng ea ts'ireletso ea kutu eo theknoloji ea Dacromet e tsejoang ka eona.

Ka bokhuts'oane, Dacromet hexagon bolt e eme e le sekontiri se tiisitsoeng, se sa sebetseng hantle, le se matla ka ho fetesisa se thibelang kutu bakeng sa lits'ebetso tse batloang haholo.
