I-Dacromet Flange Bolts: Isethulo Esiphelele Sokubopha Okuphezulu Kwe-Anti-Corrosion Fasteners

2026-10-16

1. Isingeniso ku-Dacromet Flange Bolts

Ezinhlelweni zesimanje zezimboni, ukwethembeka kwezinhlelo zokubopha kubalulekile. Phakathi kwezixazululo eziphambili kakhulu ezitholakalayo namuhla I-Dacromet flange bolts. Lawa mabhawodi akhethekile ahlanganisa izinzuzo zemishini zedizayini ye-flange nehlukile anti-ukugqwala futhi anti-ukugqwala izakhiwo ze-Dacromet coating technology.

Ibhawodi ye-flange ifaka i-flange ehlanganisiwe efana newashi ngaphansi kwekhanda. Lo mklamo usabalalisa umthwalo wokubopha phezu kwendawo enkulu, unciphisa ingozi yokulimala kwendawo, futhi ngokuvamile uqeda isidingo sewasha ehlukile. Lapho le bolt flange iphathwa I-Dacromet - i-non-electrolytic zinc-aluminium flake coating - iba yi-fastener esebenza kahle kakhulu ekwazi ukumelana nezindawo ezilimazayo isikhathi eside.

I-Dacromet coating, eyaziwa nangokuthi i-zinc flake coating, inikeza isivikelo esivelele ngokumelene nokugqwala nokugqwala. Icaciswe kabanzi kumabhawodi anamandla aphezulu (iBanga 8.8, 10.9, kanye ne-12.9) asetshenziswa ezimotweni, ezakhiweni, zasolwandle, zamandla omoya, nasezinsizeni zemishini yezimboni lapho i-zinc plating noma i-hot-dip galvanizing ingase ingafinyeleli khona.

2. Iyini I-Dacromet Coating?

I-Dacromet iwuhlelo lokunamathela olwenziwa ngezinto eziphilayo, olususelwe emanzini olwakhiwe ngokuyinhloko i-zinc namaflake e-aluminium alengiswa kusibophezelo esine-chromium. I-coating isetshenziswa ngezindlela ze-dip-spin, spray, noma i-dip-drain bese welapheka emazingeni okushisa aphakeme (imvamisa engu-300-320 ° C). Le nqubo yakha umgoqo omncane, ominyene, onezingqimba eziningi (ngokuvamile u-4–8 μm ubukhulu) obopha ngamakhemikhali ne-substrate yensimbi yebhawodi.

Ngokungafani ne-electroplating evamile, inqubo ye-Dacromet ayibandakanyi i-acid pickling noma i-electrolysis. Ngenxa yalokho, iyethula akukho hydrogen embrittlement ubungozi — inzuzo ewujuqu yamabhawodi aqine kakhulu okumele agcine ubuqotho besakhiwo ngaphansi kokulayisha kuqala okuphakeme nokulayisha ngomjikelezo.

Izimpawu Eziyinhloko Ze-Dacromet Coating kuma-Bolts

Ukumelana nokugqwala okuphezulu: Ngokuvamile idlula amahora angu-1,000 wokuhlolwa kwesifutho sikasawoti esimaphakathi (ASTM B117 / ISO 9227) ngaphandle kokugqwala okubomvu.
Ifilimu elincanyana nelifanayo: Ubukhulu obungu-4–8 μm kuphela, okugcina ukubekezelelwa kwentambo okunembile kwebhawodi.
Ukumelana nezinga lokushisa eliphezulu: Igcina ukusebenza kokuvikela kufika ku-300°C isevisi eqhubekayo.
Ukumelana kwamakhemikhali okuhle kakhulu: Imelana nosawoti womgwaqo, uketshezi lwezimoto, ama-asidi athambile, nomoya wezimboni.
Ukungqubuzana okulawulwayo: Ubudlelwano obungaguquki be-torque-tension bokuqinisa amabhawodi okuthembekile.
Ukubonakala kwensimbi esiliva-mpunga: Iyunifomu, isiphetho se-matte esipendwekayo.

3. Izinzuzo ze-Dacromet Flange Bolts

Amabhawodi e-Dacromet flange anikeza inhlanganisela eyingqayizivele yezinzuzo zemishini kanye nokuvikela indawo ezenza zithandeke ngaphezu kwamabhawudo ajwayelekile aboshwe ezindaweni ezidinga kakhulu.

I-Anti-Corrosion Eyingqayizivele kanye Nokusebenza Kwe-Anti-Rust

Isakhiwo se-zinc-aluminium flake enezendlalelo eziningi se-Dacromet sidala kokubili umthelela wokuvimbela kanye nomthelela we-anode womhlatshelo. Lo mshini ombaxambili uyahlinzeka 7 kuya ku-10 izikhathi ukumelana nokugqwala kwezingubo zendabuko ezenziwe ngama-electro-galvanized. Ikhwalithi ephezulu ye-Dacromet flange bolts ingafinyelela amahora angaphezu kwe-1,200 wokumelana ne-salt spray ngaphandle kokubonakala kokugqwala okubomvu, iqinisekisa ukuvikelwa kwesikhathi eside sokulwa nokugqwala ngisho nasezindaweni zomgwaqo ezisogwini, zasolwandle, noma ezinosawoti omningi.

Ayikho Ingozi Ye-Hydrogen Embrittlement

Amabhawodi anamandla aphezulu (ikakhulukazi iBanga le-10.9 nele-12.9) angenwa kalula yi-hydrogen embrittlement lapho ecutshungulwa yi-electroplating evamile. Inqubo ye-Dacromet iqeda i-acid pickling kanye ne-electrolytic deposition, igwema ngokuphelele isingeniso se-hydrogen. Lokhu kwenza i-Dacromet ibe i-coat ethandwayo yamabhawodi e-flange abalulekile esakhiwo kanye nokuphepha.

I-Thin Coating Ilondoloza Intambo Ilingane

Ngobukhulu obujwayelekile obungu-4–8 μm kuphela, ukunamathela kwe-Dacromet akuguquli kakhulu ububanzi bephimbo lemicu yebhawudi. Lokhu kuvumela ukusetshenziswa kwamantongomane ajwayelekile ngaphandle kwesidingo sokudlula ngaphezulu, okuvame ukudingeka ukuze kuhlanganiswe ama-galvanized dip ashisayo. Umphumela uba ukubandakanyeka okungcono kochungechunge, ukulayisha kuqala okungaguquki, nokuhlanganisa amabhawudi e-flange kalula.

4. Ukuqhathaniswa kokusebenza kwe-Bolt Coatings

Ithebula elilandelayo liqhathanisa i-Dacromet nezinye izimbotshana ezijwayelekile ezisetshenziswa kuma-bolt:

Impahla	I-Dacromet	I-Electro-Zinc Plating	I-Hot-Dip Galvanizing
Ukuqina Kokunamathela	4–8 um	5–15 μm	40-80 μm
Ukumelana Nesifutho Sosawoti (ukugqwala okubomvu)	≥ 1,000–1,200 h	100–300 h	500–800 h
Ingozi Ye-Hydrogen Embrittlement	Lutho	Phezulu (idinga ukubhaka)	Maphakathi
Ukumelana Nokushisa Okuphezulu	Kufika ku-300°C	≤ 120°C	≤ 200°C
I-Thread Fit Compatibility	Kuhle kakhulu (amantongomane ajwayelekile)	Kuhle	Idinga ukweqisa
Ukufaneleka Kwamabhawodi Amandla Aphakeme	Okufanelekile (10.9 / 12.9)	Inomkhawulo	Kuphakathi

Ithebula 1. Ukusebenza okuqhathaniswayo kokwelashwa kwendawo yebhawodi evamile.

5. Imihlahlandlela yokukhetha ye-Dacromet Flange Bolts

Lapho ucacisa amabhawodi e-Dacromet flange ephrojekthi, cabangela izici ezilandelayo ukuze uqinisekise ukusebenza kahle kwe-anti-corrosion kanye nokwethembeka okuhlanganyelwe:

1. Ukubola kwemvelo: Ukuchayeka ogwini, olwandle, kwezimboni, noma usawoti osemgwaqweni ngokuvamile kuvumela i-Dacromet yezinga B noma ngaphezulu.

2.Ibanga lamandla we-Bolt: Kumabhawodi e-flange eBanga le-10.9 kanye ne-12.9, i-Dacromet inconywa ngokuqinile ukuze kuqedwe ingozi ye-hydrogen embrittlement.

3.Ukuvezwa kwezinga lokushisa: Izicelo ezisondela ku-250-300 ° C zizuza ekuzinzeni okushisayo kwe-Dacromet.

4. Izidingo ze-torque-tension: Cacisa ijazi eligcotshisiwe (isb., PLUS® noma i-DACROLUB®) uma ukulawula ukulayisha kuqala okunembile kubalulekile.

5.Ukuhambisana nezingxenye zokukhwelana: I-Dacromet ibonisa ukuhambisana okuhle kwe-bimetallic nezingxenye ze-aluminium, ukunciphisa ingozi yokugqwala kwe-galvanic.

6. Isiphetho

Amabhawodi e-Dacromet flange amelela isixazululo esiqinile esivuthiwe, esisebenza kahle kakhulu esibhekelela ubuqotho obuhlangene bemishini kanye nokuvikelwa kwendawo yesikhathi eside. Ngokuhlanganisa izinzuzo zokusabalalisa umthwalo wekhanda le-flange nokuvelele anti-ukugqwala futhi anti-ukugqwala izakhiwo ze-zinc-aluminium flake coating, lawa mabhawodi aletha isevisi ethembekile ezindaweni ezinolaka kakhulu.

Okubalulekile okuzothathwa konjiniyela nochwepheshe bokuthengwa kwempahla kuhlanganisa:

I-Dacromet inikeza izikhathi ezingu-7-10 ukumelana nokugqwala kwe-electro-zinc plating evamile kuyilapho isala izacile ngokwanele ukuze kugcinwe ukulingana kwentambo evamile.
Inqubo engeyona eye-electrolytic iqeda ngokuphelele i-hydrogen embrittlement, iyenze ilungele amabhawodi e-flange aphezulu.
Ukuzinza okuhle kakhulu kwezinga lokushisa eliphezulu (kufika ku-300°C) nokumelana namakhemikhali kuqhubezela phambili ukwandisa amathuba okusebenza.
Idizayini ye-flange edidiyelwe yenza kube lula ukuhlanganisa futhi ithuthukise ukusebenza okuhlanganyelwe ngaphansi kokudlidliza nokulayisha ngomjikelezo.

Kungakhathaliseki ukuthi asetshenziswa ku-chassis yezimoto, izinjini zomoya zasogwini lolwandle, ingqalasizinda yasogwini, noma izisetshenziswa zezimboni ezisindayo, amabhawodi e-Dacromet flange anikeza umzila ofakazelwe wempilo yesevisi ende, ukulungiswa okuncishisiwe, nokuphepha okuthuthukisiwe. Ukucacisa ibanga elilungile le-Dacromet kanye nokuqinisekisa ukulawulwa kwekhwalithi okufanele kuzokhulisa izinzuzo zokulwa nokugqwala kanye nezokunqanda ukugqwala eziklanyelwe ukulethwa yila mabhawodi athuthukile.

Anginayo. Okulandelayo.
