2026-10-21 : kuv
1. Taw qhia
Hauv kev lag luam niaj hnub tsim thiab kev tsim kho engineering, kev ntseeg siab ntawm fasteners ncaj qha txiav txim siab txog kev nyab xeeb thiab kev pabcuam lub neej ntawm cov khoom thiab cov qauv. Countersunk hex socket bolts yog dav siv nyob rau hauv tsheb, tsheb ciav hlau, tsheb thauj mus los, machinery, lub tsev ntaub thaiv phab ntsa, cov khoom siv hauv tsev, thiab cov khoom siv hluav taws xob hauv kev lag luam vim lawv muaj peev xwm zaum yaug nrog lub workpiece nto, zoo nkauj tsos, thiab cov khoom thauj khoom sib xws. Txawm li cas los xij, cov tsoos electro-galvanized lossis kub-dip galvanized bolts feem ntau tawm tsam kom muaj kev tiv thaiv corrosion thiab xeb-tiv thaiv muaj peev xwm nyob rau hauv av, ntsev-txhaj tshuaj, acidic, los yog alkaline ib puag ncig, ua rau muaj kev pheej hmoo xws li xeb, txheej delamination, txo clamping quab yuam, thiab txawm tawg.
Qhov tshwm sim ntawm Dacromet (tseem hu ua zinc-aluminium flake txheej) thev naus laus zis muab kev daws teeb meem zoo rau qhov kev sib tw no. Dacromet countersunk hex socket bolts muab cov zinc-aluminium flake anti-corrosion txheej nrog meej countersunk hex socket qauv tsim. Lawv tsis tsuas yog xa cov khoom zoo heev corrosion thiab tiv thaiv xeb tab sis kuj khaws cov neeg kho tshuab siab zog thiab yooj yim ntawm kev sib dhos. Kab lus no qhia meej txog cov yam ntxwv thiab daim ntawv thov tus nqi ntawm Dacromet countersunk hex socket bolts los ntawm qhov kev xav ntawm txheej txheej txheem, cov qauv khoom, qhov zoo tiv thaiv corrosion, daim ntawv thov scenarios, thiab xaiv cov lus pom zoo.
2. Txheej txheem cej luam ntawm Dacromet Txheej Technology
Dacromet, tseem hu ua zinc-chromium txheej los yog zinc-aluminium txheej, yog ib qho uas tsis yog-electrolytic high-performance hlau nto kho tshuab. Ultra-fine zinc flakes thiab aluminium flakes yog tov nrog chromate thiab lwm yam inorganic binders los tsim ib txheej dej. Cov txheej txheej yog siv rau cov hlau substrate los ntawm dipping, txau, los yog txhuam, tom qab ntawd kho los ntawm qhov kub thiab txias sintering los tsim cov txheej ntom ntom tiv thaiv corrosion. Cov txheej txheem ntau txheej ntawm kev sib tshooj zinc-aluminium flakes, sib koom ua ke los ntawm chromate passivation films, tsim ib qho tshwj xeeb "labyrinth effect" barrier uas zoo thaiv kev nkag mus ntawm noo noo, oxygen, thiab corrosive xov xwm, yog li ua tau zoo rau lub sij hawm ntev los tiv thaiv corrosion thiab xeb-tiv thaiv kev ua tau zoo.
2.2 Core Advantages ntawm Dacromet Txheej
Piv nrog cov txheej txheem electro-galvanizing thiab kub-dip galvanizing, Dacromet txheej muaj cov txiaj ntsig zoo hauv kev tiv thaiv corrosion thiab tiv thaiv xeb:
- Superior ntsev-txhaj tshuaj tiv thaiv corrosion: Txheem Dacromet txheej tuaj yeem tiv taus 500-1500 teev lossis ntau dua hauv cov tshuaj ntsev ntsev-txheej txheem, deb tshaj li cov electro-galvanizing zoo tib yam (feem ntau tsuas yog 72-200 teev), txuas ntxiv kev pabcuam lub neej nyob rau hauv marine climates thiab txoj kev de-icing ntsev ib puag ncig.
- Tsis muaj kev pheej hmoo ntawm hydrogen embrittlement: Traditional electroplating tuaj yeem qhia hydrogen atoms rau hauv lub zog steel substrates, ua rau hydrogen embrittlement puas. Dacromet yog cov txheej txheem tsis-electrolytic uas tshem tawm tag nrho cov kev pheej hmoo no, ua rau nws tshwj xeeb tshaj yog haum rau cov bolts muaj zog.
- Kev kub siab zoo thiab huab cua tsis kam: Cov txheej txheem tseem ruaj khov rau kev siv mus sij hawm ntev ntawm thaj tsam 250 ° C thiab tuaj yeem tiv taus qhov kub siab dua rau lub sijhawm luv. Nws kuj tseem qhia tau hais tias muaj zog tiv thaiv ultraviolet hluav taws xob thiab cov cua kub cua sov, ua kom ruaj khov tiv thaiv corrosion thiab xeb-tiv thaiv kev ua haujlwm.
- Kev kho tus kheej thiab kev tiv thaiv cathodic: Thaum cov txheej txheej hauv zos puas, zinc thiab txhuas flakes ua raws li kev txi anodes, muab kev tiv thaiv electrochemical rau lub substrate raug thiab ntxiv dag zog rau tag nrho kev tiv thaiv corrosion thiab xeb-tiv thaiv muaj peev xwm.
3. Cov yam ntxwv ntawm Countersunk Hex Socket Bolts
Countersunk hex socket bolts (tseem hu ua flat-head hex socket screws) feature conical los yog cylindrical countersunk head design. Tom qab kev teeb tsa, lub taub hau zaum kawg ntws tawm hauv lub txee ntawm lub workpiece, ua tiav qhov du, tsis muaj qhov tsis muaj qhov tsis zoo. Lub sab hauv hex tsav yog nyob rau hauv nruab nrab ntawm lub taub hau, tso cai nruj nruj thiab tshem tawm nrog ib tug hex yuam sij thaum txo qhov kev pheej hmoo ntawm slippage.
Qhov ntau thiab tsawg ntawm M3 mus rau M20 thiab loj dua diameters, nrog rau qhov ntev customizable raws li qhov yuav tsum tau muaj. Cov ntaub ntawv feem ntau yog carbon steel, alloy steel, lossis stainless hlau, kho cua sov kom ua tiav cov chav kawm xws li 8.8, 10.9, lossis 12.9. Dacromet kev kho mob muab kev tiv thaiv corrosion thiab xeb-tiv thaiv kev tiv thaiv yam tsis muaj kev cuam tshuam cov xov raug lossis cov khoom siv kho tshuab, ua rau cov bolts tshwj xeeb tshaj yog rau cov ntawv thov uas xav tau ob qho tib si nto flatness thiab siab corrosion kuj.
4. Kev xaiv thiab kev pom zoo siv
Txhawm rau kom ua tiav qhov kev tiv thaiv corrosion thiab xeb-tiv thaiv qhov zoo ntawm Dacromet countersunk hex socket bolts, cov ntsiab lus hauv qab no raug pom zoo thaum xaiv thiab siv:
- Xaiv cov qib txheej raws li qhov kev pabcuam ib puag ncig: Standard Dacromet txheej yog tsim rau kev lag luam ib puag ncig; rau cov ntsev-txhaj tshuaj los yog hnyav corrosion ib puag ncig, thickened los yog composite kaw Dacromet coatings raug pom zoo los xyuas kom meej lub sij hawm ntev los tiv thaiv corrosion thiab xeb-tiv thaiv kev ua tau zoo.
- Nyiam cov cuab yeej cuab tam siab: Txij li cov txheej txheem Dacromet tsis muaj kev pheej hmoo hydrogen embrittlement, nws yog qhov tshwj xeeb tshaj yog tsim rau cov khoom vaj khoom tsev 8.8 thiab siab dua lub zog bolts, kom ntseeg tau tias kev sib txuas lub zog thiab kev tiv thaiv corrosion.
- Tswj lub rooj sib dhos kom zoo: Txawm hais tias kev sib txhuam coefficient ntawm Dacromet txheej yog qhov ruaj khov, nws tseem pom zoo kom txiav txim siab qhov tsim nyog nruj torque los ntawm kev sim kom tsis txhob dhau-tightening lossis qis dua uas tuaj yeem cuam tshuam kev sib txuas kev ntseeg tau.
- Tsis txhob sib cuag ncaj qha nrog cov hlau tsis sib xws: Nyob rau hauv cov xwm txheej uas galvanic corrosion yuav tshwm sim, insulating washers los yog txheej cais kev ntsuas yuav tsum tau saws los tiv thaiv cov hauj lwm zoo ntawm tag nrho cov kev tiv thaiv corrosion thiab xeb-tiv thaiv system.
5. Xaus
Dacromet countersunk hex socket bolts, nrog lawv cov tshwj xeeb zinc-aluminium flake composite txheej tshuab, txhaj muaj zog tiv thaiv corrosion thiab xeb-tiv thaiv muaj peev xwm rau hauv cov tsoos fasteners.
