Dacromet Flange Bolts: Superior Anti-Corrosion and Anti-Rust Performance for Demanding Application 

Dacromet ndi njira yosagwiritsa ntchito electrolytic, yopangidwa ndi madzi yopangidwa ndi madzi yomwe imapangidwa makamaka ndi zinc ndi aluminiyamu flakes omwazika mu chromium-inorganic binder kapena chromium-free inorganic binder. Pogwiritsidwa ntchito ndi dip-spin, spray, kapena dip-drain-drain ndipo pambuyo pake amachiritsidwa ndi kutentha, chophimbacho chimapanga chowonda (nthawi zambiri 5-15 μm), filimu yoteteza yunifolomu, yasiliva-imvi yomwe imamatira mwamphamvu ku gawo lapansi lachitsulo.

Dongosolo la anti-corrosion la Dacromet limagwira ntchito kudzera muzowonjezera zinayi:

1. Chitetezo chotchinga: Kuphatikizika kwa zinc ndi aluminium flakes kumapanga zigawo zingapo zomwe zimalepheretsa kulowa kwa chinyezi, mpweya, ndi ma ayoni owononga.

2. Chitetezo cha nsembe (galvanic): Zinc imagwira ntchito ngati nsembe ya anode, makamaka ikuwononga kuti iteteze chitsulo chapansi pa dzimbiri.

3.Kudzichiritsa wekha / kudzikonza: Zopangira ma oxidation za zinki ndi aluminiyumu zimadzaza zowonongeka pang'ono mu zokutira, kusunga umphumphu wotsutsana ndi dzimbiri.

4.Kukonda: Ma inorganic binder ndi ma passivating compounds amachepetsa kadyedwe ka zinki popereka nsembe, kumatalikitsa kukana dzimbiri.

Chifukwa ndondomekoyi imakhudza palibe pickling asidi kapena electrolysis, Dacromet ❖ kuyanika kumachotseratu chiwopsezo cha hydrogen embrittlement-ubwino wovuta kwa mabawuti amphamvu kwambiri (Makalasi 10.9, 12.9, ndi ASTM A490 / F3125). Izi zimapangitsa ma bolts a Dacromet flange kukhala odalirika pamakina komanso osamva dzimbiri komanso kuwonongeka kwa chilengedwe.

3. Ubwino waukulu wa Dacromet Flange Bolts

3.1 Kuwonongeka Kwapadera ndi Kukaniza Dzimbiri

Maboti opangidwa ndi dacromet amakwaniritsidwa nthawi zonse Maola 1,000 kapena kuposerapo kuyezetsa kusalowererapo kwa mchere wamchere (ASTM B117 / ISO 9227) popanda kuoneka kwa dzimbiri lofiira. M'mafotokozedwe ambiri, dzimbiri loyera limachedwa kupitirira maola 240-500, ndipo machitidwe odana ndi dzimbiri amaposa nthawi 7-10 kuposa electrogalvanizing wamba. Kutha koletsa dzimbiri kumeneku kumatsimikizira moyo wautali wantchito m'mphepete mwa nyanja, m'madzi, m'mafakitale, komanso m'malo amchere.

3.2 Palibe Chiwopsezo cha Hydrogen Embrittlement

Mosiyana ndi njira zopangira ma electroplating zomwe zimabweretsa haidrojeni muzitsulo zolimba kwambiri, Dacromet dip-spin kapena kupopera mbewu mankhwalawa si electrolytic. Chifukwa chake, mabawuti amphamvu kwambiri amasunga mawonekedwe awo amakina ndipo sakhala ochedwa kusweka chifukwa cha hydrogen embrittlement - kumapereka chitetezo chotsutsana ndi dzimbiri komanso chitetezo chamapangidwe.

3.3 Wopyapyala, Wovala Wofanana Ndi Kuwongolera Kwabwino Kwambiri

Kuchuluka kwa makulidwe amtundu kumayambira 5 mpaka 15 μm. Kanema wopyapyalayu sasintha kwambiri kukula kwa ulusi, kulola mtedza wamba kuti ugwiritsidwe ntchito popanda kupitilira. Chophimbacho chimalowa mkati mwa ma geometri ovuta, ulusi, ndi zopuma mofanana, kuonetsetsa kuti anti-corrosion ikuphimbidwa ngakhale pazithunzi za flange bolt.

3.4 Kukhazikika Kwambiri Kutentha ndi Zowonjezera Zowonjezera

Zovala za Dacromet zimakhalabe zogwira mtima pa kutentha kosalekeza mpaka pafupifupi 250-300 ° C, kupitirira kwambiri malire a kutentha kwa zinc plating wamba. Ubwino wowonjezera umaphatikizapo kupenta kwabwino, ma coefficients owongolera (makamaka okhala ndi ma topcoat opaka mafuta), kulumikizana kwa bimetallic ndi aluminiyamu, komanso kutsata miyezo yambiri yamagalimoto ndi chilengedwe.
