Maboliti a Dacromet Flange: Chidziwitso Chokwanira cha Zomangamanga Zapamwamba Zoletsa Kuwonongeka

2026-10-16

1. Chiyambi cha Dacromet Flange Bolts

M'mafakitale amakono, kudalirika kwa machitidwe omangirira ndikofunikira. Zina mwa njira zotsogola zomwe zilipo masiku ano ndi Maboti a Dacromet flange. Maboti apaderawa amaphatikiza ubwino wamakina wa kapangidwe ka flange ndi mwapadera anti-corrosion ndi odana ndi dzimbiri katundu wa teknoloji yokutira ya Dacromet.

Boliti ya flange imakhala ndi chophatikizira chofanana ndi washer pansi pamutu. Kapangidwe kameneka kamagawira katundu wokhomerera pamalo okulirapo, amachepetsa chiwopsezo cha kuwonongeka kwapamtunda, ndipo nthawi zambiri amachotsa kufunikira kwa makina ochapira osiyana. Pamene bolt iyi ya flange imathandizidwa ndi Dacromet - Chophimba cha zinc-aluminium chosagwiritsa ntchito electrolytic - chimakhala chomangira chogwira ntchito kwambiri chomwe chimatha kupirira malo owononga kwa nthawi yayitali.

Kupaka kwa Dacromet, komwe kumadziwikanso kuti zokutira kwa zinc flake, kumapereka chitetezo chambiri ku dzimbiri ndi dzimbiri. Amatchulidwa kwambiri pamaboti amphamvu kwambiri (Giredi 8.8, 10.9, ndi 12.9) omwe amagwiritsidwa ntchito popanga magalimoto, zomangamanga, zam'madzi, zamphamvu zamphepo, komanso makina opangira makina komwe kuyika kwa zinki kapena kuthirira kotentha kumatha kuchepa.

2. Kodi Dacromet Coating ndi Chiyani?

Dacromet ndi inorganic, zotengera madzi ❖ kuyanika dongosolo lopangidwa makamaka ndi zinki ndi aluminiyamu flakes kuyimitsidwa mu chomangira chromium muli chromium. Kupaka kumagwiritsidwa ntchito ndi dip-spin, spray, kapena dip-drain ndipo amachiritsidwa pa kutentha kwakukulu (nthawi zambiri 300-320 ° C). Njirayi imapanga chotchinga chopyapyala, chowonda, chokhala ndi mitundu yambiri (kawirikawiri 4-8 μm wandiweyani) chomwe chimagwirizanitsa ndi mankhwala ndi gawo lachitsulo la bolt.

Mosiyana ndi electroplating wamba, njira ya Dacromet simaphatikizapo pickling ya asidi kapena electrolysis. Chifukwa chake, imayambitsa palibe hydrogen embrittlement chiwopsezo - mwayi wotsimikizika wamaboliti othamanga kwambiri omwe amayenera kusunga umphumphu pansi pa kudzaza kwambiri komanso kukweza kwa cyclic.

Makhalidwe Ofunikira a Dacromet Coating pa Bolts

Superior corrosion resistance: Nthawi zambiri amapitilira maola 1,000 akuyezetsa kusalowererapo kwa mchere (ASTM B117 / ISO 9227) popanda dzimbiri lofiira.
Filimu yowonda komanso yofananira: 4-8 μm wokhuthala okha, kusunga ulusi wololera bwino wa bawuti.
Kukana kutentha kwakukulu: Imateteza magwiridwe antchito mpaka 300 ° C mosalekeza.
Kukaniza kwabwino kwa Chemical: Imakana mchere wamsewu, zamadzimadzi zamagalimoto, ma acid ochepa, komanso mlengalenga wamakampani.
Kukangana kolamulidwa: Ubale wokhazikika wa torque-tension pakulimbitsa bolt wodalirika.
Maonekedwe achitsulo asiliva-grey: Uniform, matte kumaliza komwe kumapendekekanso.

3. Ubwino wa Dacromet Flange Bolts

Ma bolts a Dacromet flange amapereka kuphatikiza kwapadera kwamakina ndi chitetezo chapamwamba chomwe chimawapangitsa kuti azikonda kuposa ma bolts ophimbidwa m'malo ovuta.

Anti-Corrosion ndi Anti-Rust Performance

Dongosolo la zinc-aluminium flake lamitundu yambiri la Dacromet limapanga zotchinga zonse komanso zotsatira za anode ya nsembe. Izi wapawiri limagwirira amapereka 7 mpaka 10 nthawi kukana dzimbiri kwa zokutira zachikhalidwe zama electro-galvanized. Mabotolo apamwamba kwambiri a Dacromet flange amatha kukwaniritsa maola oposa 1,200 osakanizidwa ndi kupopera mchere popanda kuoneka kwa dzimbiri lofiira, kuonetsetsa kuti chitetezo cha nthawi yayitali chitetezedwe ngakhale m'mphepete mwa nyanja, m'mphepete mwa nyanja, kapena mumsewu wamchere wambiri.

Palibe Chiwopsezo cha Hydrogen Embrittlement

Maboti amphamvu kwambiri (makamaka Giredi 10.9 ndi 12.9) amatha kutengeka kwambiri ndi hydrogen embrittlement akakonzedwa ndi electroplating wamba. Njira ya Dacromet imachotsa kutulutsa kwa asidi ndi kuyika kwa electrolytic, kupeweratu kuyambitsa kwa haidrojeni. Izi zimapangitsa Dacromet kukhala zokutira zomwe amakonda pamaboti olimba komanso okhudzana ndi chitetezo.

Kupaka Kwakukulu Kumasunga Ulusi Wokwanira

Ndi makulidwe wamba a 4-8 μm okha, zokutira za Dacromet sizisintha kwambiri makulidwe a ulusi wa bawuti. Izi zimalola kugwiritsa ntchito mtedza wokhazikika popanda kufunikira kowonjezera, komwe nthawi zambiri kumafunika pakuyika zokutira zamalati otentha otentha. Zotsatira zake ndi kulumikizana kwabwinoko kwa ulusi, kudzaza mosasinthasintha, komanso kuphatikiza kosavuta kwa mabawuti a flange.

4. Kufananiza kwa Magwiridwe a Bolt Coatings

Gome lotsatirali likufanizira Dacromet ndi zokutira zina zomwe zimagwiritsidwa ntchito pa mabawuti:

Katundu	Dacromet	Electro-Zinc Plating	Hot Dip Galvanizing
Kupaka makulidwe	4-8 m	5-15 m	40-80 mm
Kukaniza Kupopera Kwamchere (kuti dzimbiri lofiira)	≥ 1,000-1,200 h	100-300 h	500-800 h
Chiwopsezo cha Hydrogen Embrittlement	Palibe	Kukwera (kumafuna kuphika)	Wapakati
Kukana Kutentha Kwambiri	Kufikira 300 ° C	≤ 120°C	≤200°C
Kugwirizana kwa Thread Fit	Zabwino kwambiri (mtedza wamba)	Zabwino	Pamafunika overtapping
Kuyenerera kwa Maboti Amphamvu Kwambiri	Zabwino (10.9 / 12.9)	Zochepa	Wapakati

Tebulo 1. Kufananiza kwamankhwala ochizira bolt pamwamba.

5. Maupangiri Osankhidwa a Dacromet Flange Bolts

Mukatchula ma bolts a Dacromet flange pulojekiti, lingalirani zotsatirazi kuti muwonetsetse kuti anti-corrosion imagwira bwino ntchito komanso kudalirika kogwirizana:

1. Kuwonongeka kwa chilengedwe: Kuwonekera m'mphepete mwa nyanja, m'madzi, m'mafakitale, kapena kumsewu-mchere nthawi zambiri kumapangitsa kuti ma Dacromet akhale a Gulu B kapena apamwamba.

2.Bolt mphamvu giredi: Kwa Grade 10.9 ndi 12.9 flange bolts, Dacromet ikulimbikitsidwa kuti ithetse chiopsezo cha hydrogen embrittlement.

3. Kuwonekera kwa kutentha: Mapulogalamu akuyandikira 250-300 ° C amapindula ndi kukhazikika kwa kutentha kwa Dacromet.

4. Torque-tension zofunika: Tchulani coat yothira mafuta (monga PLUS® kapena DACROLUB®) pamene kuwongolera koyenera ndikofunikira.

5.Kugwirizana ndi zigawo zokwerera: Dacromet imasonyeza kuyanjana kwabwino kwa bimetallic ndi zigawo za aluminiyamu, kuchepetsa chiopsezo cha galvanic corrosion.

6. Mapeto

Dacromet flange bolts imayimira njira yokhwima, yogwira ntchito kwambiri yomwe imayang'anira kukhulupirika kwa makina ndi chitetezo cha nthawi yayitali. Pophatikiza ubwino wogawa katundu wa mutu wa flange ndi wopambana anti-corrosion ndi odana ndi dzimbiri katundu wa zinc-aluminium flake zokutira, mabawuti awa amapereka ntchito yodalirika m'malo ovuta kwambiri.

Zomwe zimatengera mainjiniya ndi akatswiri ogula zinthu ndi awa:

Dacromet imapereka nthawi 7-10 kukana kwa dzimbiri kwa plating wamba ya electro-zinki pomwe imakhala yowonda mokwanira kuti isunge ulusi wamba.
Njira yosagwiritsa ntchito electrolytic imachotseratu hydrogen embrittlement, ndikupangitsa kuti ikhale yabwino kwa ma bolt amphamvu kwambiri.
Kukhazikika kwapamwamba kwambiri (mpaka 300 ° C) ndi kukana kwa mankhwala kumakulitsa mwayi wogwiritsa ntchito.
Mapangidwe ophatikizika a flange amathandizira kusonkhana ndikuwongolera magwiridwe antchito olumikizana pansi pa kugwedezeka ndi kutsitsa kwa cyclic.

Kaya amagwiritsidwa ntchito mu chassis yamagalimoto, ma turbine amphepo am'mphepete mwa nyanja, zomangamanga za m'mphepete mwa nyanja, kapena zida zolemera zamafakitale, ma Dacromet flange bolts amapereka njira yotsimikizika yopita ku moyo wautali wautumiki, kuchepetsa kukonza, komanso chitetezo chowonjezereka. Kutchula kalasi yolondola ya Dacromet ndikuwonetsetsa kuwongolera koyenera kudzakulitsa mapindu odana ndi dzimbiri ndi anti-corrosion omwe ma bolt apamwambawa adapangidwa kuti apereke.

Palibe. Kenako.
