Dacromet-Coated Hex Socket Bolts-A Comprehensive Technical Guide to Dacromet Surface Treatment le Cylindrical Head Hex Socket Design 

1. Selelekela

Dacromet-coated hex socket bolts e emela tharollo e phahameng ea ts'ebetso e kopanyang theknoloji e 'meli ea bohlokoa: mokhoa o tsoetseng pele oa ho roala holim'a Dacromet le mochine oa koloi oa cylindrical head hex socket (Allen) o entsoeng ka mokhoa o nepahetseng. Liboutu tsena li sebelisoa haholo lits'ebetsong tsa likoloi, tsa kaho, tsa metsing le tsa indasteri moo ho hanyetsanang le kutu e phahameng le phetisetso ea torque e tšepahalang e leng litlhoko tsa bohlokoa.

Tataiso ena ea tekheniki e fana ka tlhahlobo e tebileng ea theknoloji ea ho roala ea Dacromet le moralo oa sebopeho sa li-cylindrical head hex socket bolts, tse koahelang sebopeho sa bona sa thepa, lits'ebetso tsa tlhahiso, litšobotsi tsa ts'ebetso le lits'ebetso tse sebetsang.

2. Dacromet Coating Technology

2.1 Dacromet ke eng?

Dacromet ke thekenoloji e tsoetseng pele, e nang le botsoalle ba tikoloho khahlanong le kutu e ntlafalitsoeng e le mokhoa o mong oa sejoale-joale ho fapana le electroplating ea setso. Ke mokhoa oa ho roala o thehiloeng metsing, o se nang electrolytic o entsoeng ka ultrafine zinki le li-flakes tsa aluminium tse kopantsoeng hammoho ka mokhoa oa ho fetola chromate. Ho roala ho sebelisoa ka mekhoa ea dip-spin kapa ho fafatsa 'me ho phekoloa ka mocheso o ka bang 300 ° C, ho etsa filimi e sireletsang e nang le mekhahlelo e mengata holim'a karoloana ea tšepe.

2.2 Sebopeho le Sebopeho sa Koahelo

Thepa ea Dacromet e na le likarolo tse 'maloa tsa bohlokoa tse sebetsang ka bonngoe ho fana ka tšireletso e ikhethang ea kutu:

Li-flakes tsa zinc (20-30%): Fana ka tšireletso ea sehlabelo (cathodic) ho substrate ea tšepe

Li-flakes tsa aluminium (10-15%): Ntlafatsa tšireletso ea lithibelo le ho hanyetsa mocheso

Chromate binder: E etsa lera le feto-fetohang le tiisang seaparo

Koloi ea mokelikeli oa lintho tse phelang: E jara likarolo tse tiileng nakong ea kopo

2.3 Dacromet vs. Liaparo tse Tloaelehileng

3. Moqapi oa Cylindrical Head Hex Socket Bolt

3.1 Likarolo tsa Sebopeho

The cylindrical head hex socket bolt, eo hangata ho buuoang ka eona tlasa DIN 912 (ISO 4762), e na le hlooho ea cylindrical (konopo) e nang le "hexagonal socket" (Allen) drive recess. Moralo ona o fana ka melemo e mengata ea meralo ho feta liboutu tse tloaelehileng tsa hlooho ea hex:

Moralo oa hlooho ea boemo bo tlase: Hlooho ea cylindrical e lula e tsitsitse kapa ka tlase ho bokaholimo, e etsa hore e be e loketseng bakeng sa likopano tse kopaneng tse nang le tumello e lekanyelitsoeng.

Internal hex drive: The hex socket e lumella torque ho sebelisoa ho tsoa ka har'a hlooho, ho fokotsa kotsi ea ho hlobola le ho nolofalletsa matla a holimo a clamping.

Sebaka sa kantle se boreleli: Ho ba sieo ha lifolete tsa hex tsa kantle ho thibela ho kena-kenana le likarolo tse haufi le ho ntlafatsa ponahalo ea botle.

Kabo e ts'oanang ea khatello ea maikutlo: jiometry ea cylindrical head e abela moroalo oa clamping ka ho lekana ho pholletsa le sebaka sa ho ikopanya, ho fokotsa khatello ea maikutlo sebakeng sa heno.

3.2 Litekanyo tse Tloaelehileng (DIN 912 / ISO 4762)

4. Likopo le Tšebeliso ea Indasteri

Li-bolts tsa hex socket tse koahetsoeng ka Dacromet li fumana ts'ebeliso e pharaletseng ho pholletsa le liindasteri tse ngata ka lebaka la motsoako oa tsona o ikhethang oa ho hanyetsa kutu le ho ts'epahala ha mochini:

Likoloi: Likopano tsa enjine, likarolo tsa chassis, litsamaiso tsa mariki, le liphanele tsa 'mele moo ts'ireletso ea nako e telele ea kutu e hlokahalang.

Kaho le meralo ea motheo: Lihokelo tsa foreime ea tšepe, lisistimi tsa marako a likharetene le likopano tsa ka ntle tse hlasetsoeng ke maemo a leholimo a mabe.

Marine le offshore: Thepa le mehaho e itšetlehileng ka ho pepesehela metsi a letsoai, moo liphahlo tse tloaelehileng li hlōlehang ka potlako.

Matla a terene le a moea: Litikoloho tse thothomelang haholo tse hlokang ho tiisa ka mokhoa o sireletsehileng le tšireletso e tšoarellang ea holim'a metsi.

Libaka tsa motlakase le tsa elektroniki: Likhabinete tsa kantle le matlo a lisebelisoa a hlokang litšepe tse sa keneng, tse sa jeng.

Li-bolts tsa hex socket tse koahetsoeng ka Dacromet li emela ho kopana ha boenjiniere bo tsoetseng pele ba holim'a metsi le moralo o nepahetseng oa mochini. Ho roala ha Dacromet ho fana ka ts'ireletso e ikhethang ea kutu ntle le likotsi tsa hydrogen embrittlement tse amanang le electroplating, athe cylindrical head hex socket configuration e fana ka phetisetso e phahameng ea torque, compact geometry, le ts'ebetso e tšepahalang ea clamping. Ka kopanelo, mahlale ana a etsa hore liboutu tsa Dacromet hex e be khetho e nepahetseng bakeng sa ho batla lits'ebetso ho pholletsa le likarolo tsa makoloi, tsa kaho, tsa likepe le tsa indasteri.

Ha liindasteri li ntse li tsoela pele ho batla bophelo bo bolelele ba ts'ebeletso, tlhokomelo e fokotsehileng, le tlhahiso e ikarabellang ea tikoloho, ho amoheloa ha li-fasteners tse koahetsoeng ka Dacromet ho lebelletsoe ho hola. Baenjiniere le litsebi tsa ho reka thepa ba lokela ho nahana ka ho hlakisa li-bolts tsa Dacromet hex bakeng sa ts'ebeliso efe kapa efe moo khanyetso ea kutu, ts'epahalo ea mochini, le moralo oa kopano e kopaneng e leng lintlha tsa bohlokoa tsa ts'ebetso.
