Ma Dacromet Flange Bolts-Anti-Corrosion Flange Fasteners okhala ndi Zinc-Aluminium Flake Coating 

Gawo 1 - Flange Bolt mwachidule

Kodi Flange Bolt N'chiyani?

Bawuti ya flange ndi bawuti yamutu ya hex yokhala ndi cholumikizira chophatikizika ngati washer pamunsi pamutu. Flange imagawira katundu wokhotakhota pamalo okulirapo, kuchepetsa kuthamanga kwa pamwamba pa zinthu zolumikizidwa ndikuletsa kuwonongeka kwa malo ofewa kapena opaka utoto. Izi zimathetsa kufunika kwa makina ochapira osiyana, kuchepetsa kusonkhana ndi kuchepetsa chiwerengero cha magawo.

Mawonekedwe Ofunika Kwambiri

Integral flange: Imagawa mphamvu yothina pamalo okulirapo kuposa mutu wamba wa hex, kuchepetsa kupsinjika ndikupewa kulowera pamwamba.

Njira yokhazikika: Mphepete mwa nyanja imalumikizika pamwamba pa makwerero, kupereka kukana koletsa kumasula popanda zina zokhoma.

Miyeso yokhazikika: Zapangidwa ku DIN 6921, ISO 4162, kapena GB/T 5787, kuwonetsetsa kusinthana kwazinthu zonse padziko lonse lapansi.

Maphunziro apamwamba: Imapezeka mu kalasi ya 8.8 ndi 10.9, yoyenera pazantchito zamapangidwe komanso zonyamula katundu.

Zofotokozera

Gawo 2 - Dacromet Coating Technology

Dacromet (达克罗) ndi mankhwala opangidwa ndi madzi, osagwiritsa ntchito electrolytic omwe amayika filimu yopyapyala ya zinki ndi aluminiyamu yolumikizana ndi ma inorganic chromium. Imagwiritsidwa ntchito pogwiritsa ntchito dip-spin-cure, imapereka magawo angapo a chitetezo cha dzimbiri popanda kulowetsa haidrojeni muzitsulo - mwayi wofunikira pazomangira zamphamvu kwambiri.

Njira Yotetezera Kuwonongeka

Chitetezo chachitetezo: Zinc flakes corrode makamaka kuteteza chitsulo gawo lapansi, ngakhale pamene zokutira ndi zikande.

Chotchinga pathupi: Kuphatikizika kwa zinc-aluminium flakes kumapanga njira yowawa yomwe imatchinga chinyezi, mpweya, ndi ma ion owononga.

Chemical passivation: Zosakaniza za chromium zimapanga zosanjikiza zomwe zimachedwetsa kusungunuka kwa zinki ndikuzichiritsa zokha pakang'ono kakang'ono.

Ubwino waukulu wa Flange Bolts

Palibe hydrogen embrittlement: Njira yosagwiritsa ntchito electrolytic - yotetezeka ku Giredi 8.8-10.9 yamphamvu kwambiri ya flange mabawuti pomwe electroplating ndi yoletsedwa.

Woonda & yunifolomu: Kupaka kwa 4-10 µm kumateteza kukwanira kwa ulusi ndi geometry ya flange. Palibe kugogodanso mtedza kumafunika.

Kupopera mchere kwa maola 500-1,200: Nthawi 5-10 kuposa plating wamba ya zinki, yoyenera kuwonetseredwa kwanthawi yayitali panja.

Zolimbana ndi kutentha: Imapirira ntchito mosalekeza mpaka 250 ° C - yabwino panja ya injini ndi zomangira zoyandikana nazo.

Zogwirizana ndi chilengedwe: Zopanda Cr⁶⁺, RoHS ndi REACH zimagwirizana.

Coating Kufananiza

Kupopera mchere pa ISO 9227 NSS. Chiwopsezo cha hydrogen embrittlement chimagwiranso ntchito pa zomangira zamagetsi za Giredi 10.9 ndi kupitilira apo.

Chidule

Maboti a Dacromet flange amapereka kuphatikiza kokakamiza kwamakina ndi chitetezo cha dzimbiri. Flange yophatikizika imathandizira kusonkhana ndikugawa katundu mofanana, ndipo Dacromet zinc-aluminium flake yokutira imapereka maola 500-1,200 akukaniza kutsitsi kwa mchere popanda hydrogen embrittlement. Zomangamangazi zimagwiritsidwa ntchito kwambiri pamagalimoto, zomangamanga, mphamvu zamphepo, ndi ntchito zapamadzi pomwe zonse zodalirika zokhomerera komanso kulimba kwa nthawi yayitali ndizofunikira.
