1. Chiyambi cha Dacromet Hex Bolts

Maboti a Dacromet hexagon amayimira gulu logwira ntchito kwambiri la zomangira zomwe zimapangidwira kuti zisamachite dzimbiri komanso kupewa dzimbiri kwa nthawi yayitali. Mabotiwa amaphatikiza kudalirika kwamakina a ma bawuti ammutu a hexagonal ndi zokutira zapamwamba za zinc-aluminium zomwe zimatchedwa Dacromet (zomwe zimatchedwanso Dacro kapena zinc-flake coating). Zotsatira zake ndi bawuti yomwe imapereka magwiridwe antchito abwino kwambiri odana ndi dzimbiri m'malo ovuta pomwe imasunga ulusi wolondola wa geometry ndi kulimba kwamphamvu kwambiri.

Mosiyana ndi ma bawuti opaka malata wamba opangidwa ndi ma electro-galvanized kapena otentha, ma bolts a Dacromet hexagon amagwiritsa ntchito zokutira zopanda electrolytic. Izi zimachotsa chiwopsezo cha hydrogen embrittlement-ubwino wofunikira kwa ma bolt amphamvu kwambiri a giredi 8.8, 10.9, ndi 12.9. Filimu yopyapyala, ya yunifolomu ya Dacromet (yomwe nthawi zambiri imakhala 4-12 μm) imapereka kukana kwabwino kwa kupopera mchere, kukana kutentha, komanso kukhazikika kwa dzimbiri, zomwe zimapangitsa kuti mabawuti awa akhale osankhidwa bwino pamagalimoto, zomangamanga, mphamvu zamphepo, zam'madzi, ndi zida zamafakitale.

2. Kodi Dacromet Coating ndi Chiyani?

Dacromet ndi ukadaulo wopangira zitsulo, wopangidwa ndi madzi, womwe umapangidwa makamaka ndi ma ultra-fine zinc flakes, aluminium flakes, ndi zomangira chromium. Akagwiritsidwa ntchito pa bawuti ya hexagon ndi kuchiritsidwa pa kutentha kokwera (pafupifupi 300 ° C), ma flakes amalumikizana m'magulu angapo, kupanga chotchinga chowundana, chachitsulo chotuwa chasiliva. Kapangidwe kazinthu zambiri kameneka kamapanga chotchinga chakuthupi kutsutsana ndi chinyezi ndi ma electrolyte komanso njira yodzitetezera ya anodic yomwe imatsutsa mwachangu kupanga dzimbiri.

Kupaka pa Dacromet hexagon bolt kumapereka chitetezo chapawiri: zinc flakes zimakhala ngati nsembe ya anode, zimawononga makamaka kuteteza gawo lapansi lachitsulo, pomwe ma flakes a aluminiyumu ndi matrix a inorganic amathandizira zotchinga ndikuwongolera kukana kwa dzimbiri. Chifukwa chakuti njirayi si ya electrolytic, palibe haidrojeni yomwe imalowetsedwa muzitsulo zachitsulo, kusunga umphumphu wathunthu wamakina azitsulo zamphamvu kwambiri.

3. Dacromet Coating Process for Hexagon Bolts

Kupanga kwa Dacromet hexagon bolt yodalirika kumatsata ndondomeko yoyendetsedwa bwino yokonzedwa kuti ipangitse kumamatira, kufanana, ndi ntchito yotsutsa dzimbiri:

1.Kukonzekera Pamwamba: Bawutiyo imayeretsedwa bwino ndikuchotsa makina kapena alkaline. Acid pickling amapewa mwadala kuteteza mayamwidwe wa haidrojeni zomwe zingachititse kuti embrittlement wa mkulu-mphamvu mabawuti.

2. Coating Application: Maboti a hexagon otsukidwa amamizidwa mkati, kupopera kapena kuviika mu Dacromet slurry yokhala ndi zinki ndi aluminiyamu. Dip-spin ndiye njira yodziwika bwino yamafakitale yopangira ma bolts ambiri.

3. Kuchiritsa / Kusokoneza: Maboti ophimbidwa amawotcha pafupifupi 300 ° C. Pa kuchiritsa ndi binder amachitira ndi zitsulo flakes sinter mu mosalekeza, mwamphamvu omatira inorganic filimu.

4.Kuwunika kwa Ubwino: Maboti omaliza a Dacromet hexagon amawunikidwa kuti akute makulidwe, kumamatira, mawonekedwe, ndi ntchito yopopera mchere kuti zitsimikizire chitetezo chosagwirizana ndi dzimbiri.

4. Kufananiza kwa Magwiridwe a Anti-Corrosion Coatings

Gome lotsatirali likufotokozera mwachidule kusiyana kwakukulu pakati pa mabawuti a Dacromet hexagon ndi mabawuti omalizidwa ndi njira zachikhalidwe zolimbana ndi dzimbiri:

Katundu	Dacromet	Electro-Galvanizing	Hot Dip Galvanizing
Kupaka makulidwe	4-12 m	5-15 m	40-85 m
Kupopera mchere (palibe dzimbiri)	600–1,200+ h	100-300 h	500-800 h
Chiwopsezo cha Hydrogen Embrittlement	Palibe	Wapamwamba (akufunika kuphika)	Low-Medium
Kukaniza Kutentha	Kufikira 300 ° C	≤ 100–120 °C	≤200 °C
Thread Fit Impact	Mtedza wochepa / wokhazikika zili bwino	Zochepa	Zofunika (zingafunike mochulukira)
Mbiri Yachilengedwe	Potengera madzi, kuipitsidwa kochepa	Thandizo lamadzi otayira limafunikira	Zinc slag / madzi onyansa

5. Kugwiritsa Ntchito Ma Dacromet Hexagon Bolts

Chifukwa cha kukana kwawo kwa dzimbiri, chikhalidwe cha hydrogen-embrittlement-free, ndi kulondola kwazithunzi, ma bolts a Dacromet hexagon amatchulidwa kwambiri m'magawo ovuta:

Galimoto zamagalimoto ndi zamalonda: Zida za injini, chassis, kuyimitsidwa, ndi zomangira pansi pa thupi zomwe zimayenera kukana mchere wamsewu ndi chinyezi.
Mphamvu yamphepo ndi mphamvu zongowonjezedwanso: Maboti a Tower, nacelle, ndi maziko omwe amawonekera kumadera akunyanja kapena kunyanja.
Zomangamanga ndi zomangamanga: Malumikizidwe omangika, milatho, ndi zitsulo zakunja zomwe zimafuna ntchito yolimbana ndi dzimbiri kwa nthawi yayitali.
Marine ndi Offshore: Zipangizo ndi ma bolts opangidwa ndi mlengalenga wodzaza ndi mchere mosalekeza.
Makina a mafakitale ndi zida zolemetsa: Malunji amphamvu kwambiri m'malo omwe kudalirika kwamakina ndi chitetezo cha dzimbiri ndizofunikira.

6. Tsatanetsatane waukadaulo ndi Magwiridwe Antchito

Zizindikiro zodziwika bwino zamaboliti a hexagon okhala ndi Dacromet ndizofupikitsidwa pansipa. Miyezo yeniyeni imadalira kalasi yakuphimba (mwachitsanzo, Dacromet 320 kapena 500) ndi magawo opangira.

7. Mapeto

Maboti a Dacromet hexagon amapereka njira yamakono, yogwira ntchito kwambiri pamapulogalamu omwe amafunikira mphamvu zamakina apamwamba komanso kukana kwa dzimbiri kwanthawi yayitali. Pophatikiza zokutira zopyapyala za zinc-aluminiyamu zopanda electrolytic ndi geometry yeniyeni ya hexagonal, mabawutiwa amachotsa ziwopsezo za hydrogen-embrittlement pomwe akupereka kukana kwa kupopera mchere kuposa momwe zimakhalira ndi electro-galvanizing. Kukana kwawo kutentha kwabwino, kugwirizana kwa ulusi, komanso kuyanjana ndi chilengedwe kumawonjezera kufunikira kwawo pamagalimoto, mphamvu, zomangamanga, ndi mafakitale.

Potchula zomangira zopangira zida zowonongeka, mainjiniya ndi ogula amatembenukira kumabowuti a hexagon okhala ndi Dacromet ngati njira yodalirika, yolimbana ndi dzimbiri yomwe imateteza mafupa ovuta kwazaka zambiri. Kuwongolera koyenera komanso kutsimikizira kwabwino kumatsimikizira kuti bolt iliyonse imapereka chitetezo chokwanira chomwe ukadaulo wa Dacromet umadziwika.

Mwachidule, bolt ya Dacromet hexagon imayima ngati chotsimikizirika, chotsika mtengo, komanso chomangira chapamwamba kwambiri cha anti-corrosion pakugwiritsa ntchito zovuta kwambiri.
