Umhlahlandlela Ophelele we-Dacromet Countersunk Hex Socket Bolts - Isixazululo Esithandwayo Se-Fastener Esinomsebenzi Ovelele Wokulwa Nokugqwala kanye Nokugqwala Kokuvimbela 

Ukuvela kwe-Dacromet (eyaziwa nangokuthi i-zinc-aluminium flake coating) ubuchwepheshe buhlinzeka ngesisombululo esihle kule nselele. I-Dacromet countersunk hex socket bolts ihlanganisa i-zinc-aluminium flake ye-anti-corrosion esezingeni eliphezulu ehlanganiswe nomklamo wesakhiwo wesokhethi we-countersunk hex. Azilethi nje kuphela ukumelana nokugqwala okuhle kakhulu nokuvimbela ukugqwala kodwa futhi zigcina amandla emishini aphezulu kanye nokuhlangana kalula. Lesi sihloko sethula ngokuphelele izici zobuchwepheshe kanye nenani lesicelo se-Dacromet countersunk hex socket bolts kusukela kumbono wezimiso zokumboza, ukwakheka komkhiqizo, izinzuzo zokulwa nokugqwala, izimo zohlelo lokusebenza, nezincomo zokukhetha.

2. Uhlolojikelele lwe-Dacromet Coating Technology

I-Dacromet, ebizwa nangokuthi i-zinc-chromium coating noma i-zinc-aluminium coating, iwubuchwepheshe bokwelapha bensimbi obungeyona i-electrolytic high-performance metal surface. Amaflake e-zinc acwebe kakhulu nama-aluminium flakes axutshwe ne-chromate nezinye izibophezelo ze-inorganic ukuze kwakhe ukunamathela emanzini. I-coating isetshenziswa ngokufanayo ku-substrate yensimbi ngokucwiliswa, ngokufafaza, noma ukuxubha, bese yelapheka nge-sintering ephezulu yokushisa ukuze kwakhiwe ungqimba oluminyene oluphikisana nokugqwala. Lesi sakhiwo esinezendlalelo eziningi sama-flakes e-zinc-aluminium agqagqene, ahlanganiswe amafilimu e-chromate passivation, sakha umgoqo oyingqayizivele "we-labyrinth effect" ovimba ngempumelelo ukungena komswakamo, umoya-mpilo, kanye nemithombo yezindaba ebolayo, ngaleyo ndlela kuzuzwe ukusebenza okuvelele kwesikhathi eside okunqanda ukugqwala kanye nokusebenza kokuvimbela ukugqwala.

2.2 Izinzuzo Eziyinhloko Ze-Dacromet Coating

Uma kuqhathaniswa nezinqubo zendabuko ze-electro-galvanizing kanye ne-hot-dip galvanizing, ukunamathela kwe-Dacromet kunikeza izinzuzo ezibalulekile ekuvimbeleni ukugqwala nokugqwala:

• Ukumelana nokugqwala okuphezulu kwesifutho sikasawoti: Izingubo ezijwayelekile ze-Dacromet zingamelana namahora angama-500-1500 noma ngaphezulu ekuhlolweni kwesifutho sikasawoti esingathathi hlangothi, okudlula kude i-electro-galvanizing evamile (imvamisa amahora angama-72-200 kuphela), andisa kakhulu impilo yesevisi yebhawodi ezindaweni zasolwandle nasezindaweni zikasawoti zokukhipha i-icing emgwaqeni.
• Abukho ubungozi be-hydrogen embrittlement: I-electroplating yendabuko ingethula ama-athomu e-hydrogen endaweni engaphansi yensimbi enamandla amakhulu, kubangele ukuphuka kwe-hydrogen embrittlement. I-Dacromet iyinqubo engeyona i-electrolytic eqeda ngokuphelele le ngozi, iyenze ifaneleke ngokukhethekile kumabhawodi aphezulu.
• Izinga lokushisa eliphezulu kakhulu kanye nokumelana nesimo sezulu: Ukugqoka kuhlala kuzinzile ukuze kusetshenziswe isikhathi eside cishe ku-250°C futhi kungamelana namazinga okushisa aphakeme isikhathi esifushane. Iphinde ibonise ukumelana okuqinile emisebeni ye-ultraviolet nemijikelezo yokushisa okumswakama, iqinisekisa ukusebenza okuqinile kokuqeda ukugqwala kanye nokuvimbela ukugqwala.
• Ukuziphulukisa nokuvikeleka kwe-cathodic: Uma okunamathelayo konakalisiwe endaweni, i-zinc flakes ne-aluminium kusebenza njenge-anode yomhlatshelo, okuhlinzeka ngokuvikelwa kwe-electrochemical ku-substrate eveziwe futhi kuthuthukise nakakhulu amandla okuvimbela ukugqwala kanye nokuvimbela ukugqwala.

3. Izici Zesakhiwo Se-Countersunk Hex Socket Bolts

Amabhawodi esokhethi e-Countersunk hex (abuye aziwe ngokuthi izikulufu zesokhethi ye-hex-head) afaka umklamo wekhanda oyikhoyili noma oyisilinda. Ngemuva kokufakwa, ikhanda lihlala lihlanzekile ngokuphelele ngaphakathi kwe-countersink ye-workpiece, ifinyelela indawo ebushelelezi, engena-protrusion. I-hex drive yangaphakathi itholakala maphakathi nekhanda, okuvumela ukuqiniswa okuphumelelayo nokususwa ngokhiye we-hex kuyilapho kunciphisa ubungozi bokushelela.

Osayizi abajwayelekile basuka ku-M3 kuye ku-M20 namadayamitha amakhulu, anobude obungenziwa ngokwezifiso ngokuya ngezidingo. Izinto ezisetshenziswayo ngokuvamile ziyi-carbon steel, i-alloy steel, noma insimbi engagqwali, ephathwa ngokushisa ukuze kuzuzwe izigaba zezakhiwo ezifana no-8.8, 10.9, noma 12.9. Ukwelashwa kwe-Dacromet kunikeza isivikelo esibanzi sokulwa nokugqwala kanye nokuvikela ukugqwala ngaphandle kokuphazamisa ukunemba kwentambo noma izakhiwo zemishini, okwenza lawa mabhawodi afaneleke ikakhulukazi izinhlelo zokusebenza ezidinga kokubili ukugqama komhlaba kanye nokumelana nokugqwala okuphezulu.
