Dacromet Hex Socket Bolts: Ake Ake Anti-Corrosion Ka tutuki te Hoahoa Whakanoho Tika
2026-07-27
Ko nga tutaki hex hex Dacromet e tohu ana i te whakakotahitanga o nga hangarau whakapiri tino nui e rua: ko te punaha whakakikoruatanga anti-corrosion teitei o Dacromet me te ahuahanga porotakaroa-upoko-upoko (Allen). Ka hono tahi, ka tukuna e ratou he otinga whakamaarama e mau ana i nga taiao tino kino i te wa e taea ai te whakaurunga teitei-torque tika, na te mea he mea nui ki nga miihini, moana, hangahanga me nga miihini taumaha puta noa i te ao.
1. Hangarau Whakakikorua Dacromet
Ko te Dacromet he punaha whakakikorua wai-kore i hangaia i te tuatahi mo te waro me te kowiri tira. Kaore i rite ki te konutea whakakikoruatia tikanga, ka mahi a Dacromet i te mahi matū kore-chromium (he iti-chromium ranei) ka hanga he arai paparanga-maha o te konutea me te tawerewere konumohe. Ko te hua ko te mutunga o te hiriwa-hinahina e whakakotahi ana i te noho koretake me te mahi whakamarumaru.
Ka mahi tahi nga paparanga e toru ki te whakarato whakamarumaru matawhānui:
Ko te paparanga papa tawerewere konutea-konumohe – he whakamarumaru patunga tapu (cathodic), he pai ake te waikura ki te maru i te tïpako rino o raro, ko nga tawerewere konumohe hei whakamarumaru arai.
Paparanga-waenganui o te passivation - he kiriata chromate/silicate parakore e hiri ana i te hanga tawerewere konganuku, te aukati i te rehu tote, te whakaeke matū, me te wera i tua atu i te whakakikorua konutea.
Ko te koti hiri waro o runga (he kowhiringa) – ka whakanui ake i te mahi aukati i te taipana me te aukati huarere, me te whakaputa i te ahua o te ahua hiriwa-hina me te iti o te whakarea waku.
Ripanga 1. Te Whakataurite Atete Te Waikura (Whakamātautau Mapu Tote, NSS)
| Momo whakakikorua | Nga haora Rehu Tote | Mātotoru (μm) | Taupānga Angamaheni |
| Dacromet | ≥ 1,000 – 3,000 | 6 – 10 | Moana / waka |
| Ruspert | ≥ 1,000 – 3,000 | 3 – 5 | Waho / moana |
| Zn-Ni koranu whakakikorua | ≥ 720 – 1,000 | 8 – 12 | Motika |
| Whakakikoruatia Zn tikanga | 96 – 240 | 5 – 8 | Roto / whanui |
2. Hex Socket Bolts
Hex poupou poupou, e mohiotia ana ko te poupou mahunga potae potae, Allen bolts ranei, he upoko porotakaroa me te puku hexagonal o roto. Ma tenei ahuahanga ka taea te tuku taipana teitei ake me te ahua iti ake o te mahunga ka whakatauritea ki nga tutaki hex o waho, na te mea he pai mo nga tono whai waahi iti, ki te waahi ranei e hiahiatia ana te ahua ma.
Ko nga waahanga hoahoa matua ko:
Mahunga porotakaroa me te puku hex roto – ka whakaae ki nga taviri hex paerewa mo te whakaurunga taipana teitei me te iti o te mahunga o te mahunga; Ka rite nga rahi o te puku ki te ISO 2936, ASME B18.3 ranei.
Miro katoa, he wahanga ranei – ka tohatoha nga momo miro-katoa i te uta ki runga i te roa whakauru; Ko nga momo miro-waahanga e whakarato ana i te hiu kore miro kaha ake mo nga tono kutikuti.
Te maitai koranu kaha teitei (8.8 / 10.9 / 12.9) – ma te whakamaarama i te wera hei whakarite i te kaha o te kaha ki te 1,220 MPa, e tika ana mo nga kawenga hihiri me nga hononga whakahirahira.
Te whakaoti mata o Dacromet – ka whakarato ≥ 1,000 haora o te whakamarumaru tote-mapu me te kore he hauwai, e pai ana mo nga toromoka kaha-nui kei te kore e pai te whakakikorua hiko.
Ripanga 2. Nga Whakatakotoranga Puawai Tupapa Hex Dacromet (Tauturu Akomanga 8.8)
| Rahi | Miro Dia. (mm) | Teitei o te Upoko (mm) | Min. Maama (MPa) | Taupānga Angamaheni |
| M4 | 4 | 4 | 800 | Hikohiko / taputapu |
| M5 | 5 | 5 | 800 | Huihuinga marama |
| M6 | 6 | 6 | 800 | Nga taonga / miihini |
| M8 | 8 | 8 | 800 | Miihini / motuka |
| M10 | 10 | 10 | 830 | Nga hononga hanganga |
| M12 | 12 | 12 | 830 | Nga miihini taumaha |
3. Whakarāpopototanga
Ko nga tutaki hex hex Dacromet e whakakotahi ana i te pai ake o te aukati waikura o te punaha whakakikorua parakore a Dacromet (ka eke ki te 1,000–3,000 haora o te whakamarumaru tote-mapu me te kore hauwai embrittlement) me te taipana teitei, te hoahoa iti-tohu o te raka turanga hex. Ma tenei whakaurunga ka taea te whakapumau pono i roto i nga taiao uaua - mai i te chassis me nga punaha pakaru ki nga hanganga moana me nga taputapu o waho - me te pupuri i te mana taipana tika me te mauroa mo te wa roa. I te mea e kaha haere ana nga umanga ki nga kaitoro e taurite ana te mahi, te haumaru, me te roa o te oranga, kua riro ko Dacromet hex socket bolts hei whiringa pai mo nga miihini me nga OEM puta noa i te ao.
