Dacromet Hexagonal Bolts | Tekheniki Overview 

1. Selelekela

Liboutu tsa hexagonal, tse tsejoang ka hore ke liboutu tsa hex, ke tse ling tsa li-fasteners tse sebelisoang haholo boenjiniere le kaho. Ha e ntlafatsoa ka theknoloji ea ho roala ea Dacromet, liboutu tsena li fana ka khanyetso e ikhethang ea kutu, botšepehi ba mochini, le ho ts'epahala ha nako e telele esita le maemong a thata ka ho fetesisa. Sengoliloeng sena se fana ka tlhaloso e qaqileng ea li-bolts tsa hexagonal tsa Dacromet, tse koahelang sebopeho sa tsona, melemo, ts'ebetso ea tlhahiso, litlhaloso tsa tekheniki, le lisebelisoa tsa indasteri.

Dacromet ke mokhoa oa ho roala zinki-flake o qalileng o etselitsoe indasteri ea likoloi. E na le li-flakes tsa zinki le aluminium tse kopantsoeng ke matrix a inorganic chromate. Ho fapana le mekhoa e tloaelehileng ea electroplating kapa hot-dip galvanizing, ts'ebetso ea Dacromet ha e na motlakase, e hlahisang lesela le lesesaane empa le le matla haholo le sireletsang le sa hlahiseng hydrogen embrittlement-e leng molemo oa bohlokoa bakeng sa li-fasteners tse matla haholo.

Dacromet Coating ke eng?

Dacromet (eo hape e bitsoang coating ea zinc-flake) ke metsi a entsoeng ka metsi, a sa tloaelehang a entsoeng ka phofo ea zinki, phofo ea aluminium le li-binders tsa chromate. E sebelisoa ka mokhoa oa dip-spin kapa oa ho fafatsa o lateloa ke ho phekola ka mocheso o phahameng (hoo e ka bang 300 ° C), ho roala ho etsa mokoallo o nang le mekhahlelo e mengata o fanang ka tšireletso ea cathodic, tšireletso ea mokoallo, le litšobotsi tsa ho ipholisa.

Botenya bo tloaelehileng ba filimi e ommeng bo tloha ho li-micrometer tse 4 ho isa ho tse 12, tse tšesaane haholo ho feta tse tloaelehileng tsa hot-dip galvanizing (50–80 μm). Ho sa tsotellehe boemo ba eona bo tšesaane, libaka tse koahetsoeng ke Dacromet li lula li mamella lihora tse fetang 1,000 tsa tlhahlobo ea letsoai-spray e sa nke lehlakore ntle le ponahalo ea mafome a khubelu.

2. Melemo ea Bohlokoa ea Dacromet Hex Bolts

Dacromet hexagonal bolts e fana ka motsoako o ikhethang oa thepa e fetang liphekolo tse ngata tsa setso:

• Superior Corrosion Resistance: Ts'ebetso ea ho fafatsa letsoai e feta lihora tse 1,000-1,200 (ISO 9227 / ASTM B117), hoo e ka bang makhetlo a 7-10 ho feta electro-galvanizing e tloaelehileng.
• Ha ho na Hydrogen Embrittlement: Ts'ebetso e seng ea electrolytic e felisa ho kenngoa ha hydrogen, ho etsa hore Dacromet e be e loketseng bakeng sa liboutu tse phahameng (Kereiti ea 8.8, 10.9, 12.9 le ASTM A490).
• Botsitso ba Mocheso o Phahameng: Mocheso o tsoelang pele oa tšebeletso ho fihlela ho 300 ° C ntle le ho senyeha ha filimi e sireletsang-hole ho feta liaparo tse tloaelehileng tsa zinki.
• Khoele e Ntle e Ntle le Botsitso ba Dimensional: Ho roala ho tšesaane ho boloka geometry ea khoele 'me e lumella kopano e boreleli ka linate tse tloaelehileng.
• Paintability e Ntle le ho Recoatability: Ho khomarela ka matla ho li-topcoats tsa manyolo ho etsa hore ho be le botle bo eketsehileng kapa ho qeta ho sebetsa.
• Tšebelisano ea Bimetallic: E sebetsa hantle ha e kopana le aluminium le lisebelisoa tse ling tse sa tšoaneng, e fokotsa kotsi ea galvanic corrosion.

3. Mokhoa oa Tlhahiso

Ts'ebetso ea ho roala ea Dacromet bakeng sa liboutu tse hexagonal ke tatellano e laoloang ka hloko e netefatsang tšireletso e ts'oanang le ts'ebetso e phahameng:

1. Tokiso ea Sebaka: Liboutu li hloekisoa ka ho feletseng 'me li tlotsoa ho tlosa oli, oxides le litšila. Ha ho hlokahale pickling ea asiti, ho fokotsa kotsi ea haedrojene.
2. Tšebeliso ea Dip-Spin: Likarolo li qoelisoa ka ho emisoa ha Dacromet e nang le metsi ebe li ohloa ka lebelo le laoloang ho fihlela botenya ba filimi e ts'oanang le ho tlosa ho roala ho feteletseng.
3. Pheliso ea Pele le Pheliso ea ho Qetela: Mocheso o fokolang pele o apehoa o etsa hore metsi a be mouoane, 'me a lateloe ke sintering ea mocheso o phahameng (~300°C) e kopanyang li-flakes tsa zinc-aluminium hore e be lesela le teteaneng, le khomarelang.
4. Tlhahlobo ea Boleng: Botenya ba ho roala, ho khomarela (teko ea sefapano), ponahalo, le sampole ea ho fafatsa letsoai li etsoa ho netefatsa ho tsitsa ha batch.

4. Litlhaloso tsa Theknoloji & Maemo

Li-bolts tsa hexagonal tsa Dacromet li etsoa ho latela maemo a mangata a machaba 'me li fumaneha ka lihlopha tse ngata tsa thepa.

5. Likopo tsa indasteri

Ka lebaka la motsoako oa bona o ikhethang oa matla le ho hanyetsa kutu, liboutu tsa Dacromet tse hexagonal li hlalositsoe makaleng a mangata a boima:

6. Qetello

Dacromet hexagonal bolts e emela tharollo e tiileng e butsoitseng, e sebetsang hantle haholo e koalang lekhalo lipakeng tsa masela a tloaelehileng a zinki le mefuta e meng e theko e boima joalo ka tšepe e sa hloekang kapa lisebelisoa tse khethehileng tsa alloy. Theknoloji ea tsona ea filimi e tšesaane e fana ka tšireletso e ikhethang ea ho bola, e felisa ho ameha ha haeterojene, e tšoarella ka mokhoa o nepahetseng hantle, 'me e mamella mocheso o phahameng—e leng litšobotsi tse etsang hore e be tsa bohlokoa haholo mekhoeng ea kajeno ea boenjiniere.

Ha liindasteri li ntse li tsoela pele ho batla bophelo bo bolelele ba ts'ebeletso, tlhokomelo e fokotsehileng, le ts'epo e phahameng tlas'a maemo a mabifi a tikoloho, ho amoheloa ha li-fasteners tse koahetsoeng ka Dacromet ho lebeletsoe ho atoloha ho ea pele. Ka ho khetha kereiti e nepahetseng, boholo le litlhaloso tsa ho roala, baqapi le litsebi tsa ho reka thepa ba ka fihlela katleho ea tekheniki le ts'ebetso e baballang chelete e ngata.

Bakeng sa likhothaletso tse tobileng projeke kapa maqephe a data a tekheniki, ikopanye le barekisi ba nang le litsebo le litsebi tsa ho roala.
