Dacromet Coating Supplier | Corrosion-Resistant Finish rau Automotive & Kho vajtse 

Dacromet txheej yog ib qho kev ua tau zoo, dej-raws li inorganic zinc flake txheej txheej txheej tsim los muab kev tiv thaiv corrosion zoo tshaj rau tsheb thiab kho vajtse fasteners. Tsis zoo li ib txwm siv electroplating, nws muaj kev tiv thaiv tshwj xeeb tiv thaiv ntsev tsuag, tiv thaiv tshav kub txog 300 ° C, thiab tshem tawm hydrogen embrittlement txaus ntshai. Raws li ib tug ua lag luam nrog ntau tshaj li ob xyoo lawm ntawm kev txawj ntse, Hebei Fujinrui Hlau Khoom Co., Ltd. muab precision-engineered Dacromet tiav uas ua tau raws li nruj raws li thoob ntiaj teb cov qauv, xyuas kom meej durability rau cov ntaub ntawv tseem ceeb hauv kev lag luam.

Dacromet txheej yog dab tsi thiab nws ua haujlwm li cas?

Dacromet yog lub npe khoom lag luam uas tau dhau los ua qhov sib txawv ntawm cov zinc flakes zoo hauv cov khoom lag luam. Technically, nws yog txheej txheem uas tsis yog-electrolytic txheej txheem uas siv ib tug sib tov ntawm zinc thiab txhuas flakes raug tshem tawm nyob rau hauv ib tug chromate los yog chrome-dawb tov. Qhov no tsim ib qho kev tiv thaiv zoo uas tiv thaiv steel substrates los ntawm oxidative corrosion.

Kev Tshawb Fawb Tom Qab Zinc Flake Protection

Kev ua tau zoo ntawm dacromet txheej nyob rau hauv nws tshwj xeeb dual-tiv thaiv mechanism:

• Kev Tiv Thaiv Barrier: Qhov sib tshooj zinc thiab txhuas flakes tsim ib daim thaiv lub cev uas tiv thaiv ya raws, oxygen, thiab corrosive agents los ntawm kev ncav cuag lub hauv paus hlau.
• Sacrificial (Cathodic) Kev Tiv Thaiv: Zinc ua raws li anode txheeb ze rau hlau. Yog hais tias lub txheej yog khawb los yog puas, zinc corrodes nyiam dua, tiv thaiv cov hlau hauv qab los ntawm xeb.

Qhov kev sib xyaw ua ke no ua kom ntseeg tau tias txawm tias nyob rau hauv ib puag ncig hnyav, xws li cov khoom siv hauv tsheb hauv qab lossis cov khoom siv sab nraum zoov, cov txheej txheem kev ncaj ncees ntawm lub fastener tseem nyob twj ywm rau lub sijhawm ntev.

Cov Cheebtsam tseem ceeb ntawm Txheej Txheej Txheej

Ib tug raug Dacromet system muaj ob lub hauv paus txheej txheem:

• Base tsho: Muaj zinc thiab txhuas flakes uas muab cov thawj corrosion kuj.
• Lub tsho sab saum toj: Ib txheej txheej sealing uas txhim kho adhesion, txhim kho kev puas tsuaj, thiab tuaj yeem hloov kho kom hloov pauv kev sib txhuam coefficients (tseem ceeb rau bolt zawm torque).

Vim li cas thiaj xaiv Dacromet Tshaj Lij Choj Electroplating?

Rau engineers thiab procurement managers nyob rau hauv lub automotive thiab kev tsim sectors, xaiv qhov zoo nto tiav yog ib qho tseem ceeb heev. Kev lig kev cai zinc electroplating tau ntev tau tus qauv, tab sis dacromet txheej muaj qhov zoo sib xws uas hais txog cov kev txwv ntawm cov thev naus laus zis qub.

Tshem tawm ntawm Hydrogen Embrittlement

Ib qho kev pheej hmoo tseem ceeb tshaj plaws hauv plating high-strength steel fasteners (Qib 10.9, 12.9, lossis siab dua) yog hydrogen embrittlement. Thaum lub sij hawm electroplating, hydrogen atoms tuaj yeem nkag mus rau hauv cov hlau lattice, ua rau muaj kev puas tsuaj sai sai hauv kev ntxhov siab. Txij li Dacromet yog cov txheej txheem tsis-electrolytic, dip-spin lossis khib-coat txheej txheem, nws tsis tsim hydrogen ntawm lub cathode nto. Qhov no ua rau nws yog qhov kev xaiv nyab xeeb tshaj plaws rau lub zog tensile lub zog bolts thiab cov ntsia hlau siv hauv cov ntawv thov kev nyab xeeb tseem ceeb.

Superior Corrosion Resistance

Cov txheej txheem zinc plating feem ntau muaj 48 mus rau 96 teev ntawm cov tshuaj ntsev ntsev ua ntej cov xeb liab tshwm. Nyob rau hauv sib piv, ib tug zoo siv dacromet txheej tuaj yeem tiv taus ntawm 480 mus rau 1,000+ teev hauv nruab nrab ntsev tshuaj tsuag tshuaj ntsuam (NSS), nyob ntawm seb cov thickness thiab topcoat formulation. Qhov kev ua neej ntev no txo ​​cov nqi txij nkawm thiab txuas ntxiv lub neej ntawm cov tsheb thiab cov khoom siv sib dhos.

Thaum tshav kub kub Resistance thiab Thermal Stability

Automotive engines thiab tso pa system ua haujlwm ntawm qhov kub thiab txias. Organic coatings xws li xim los yog tej yam polymers yuav degrade los yog discolor. Dacromet's inorganic muaj pes tsawg leeg tso cai rau nws nyob ruaj khov thiab khaws nws cov khoom tiv thaiv corrosion ntawm qhov kub txog li 300 ° C (572 ° F). Qhov kev ruaj ntseg thermal no yog qhov tseem ceeb rau lub cav mounts, cov khoom siv hluav taws xob, thiab cov khoom siv turbocharger.

Kev siv Dacromet Txheej hauv Kev Lag Luam

Lub versatility ntawm dacromet txheej ua rau nws indispensable nyob rau hauv ntau yam sectors. Nws lub peev xwm los muab nyias, tsis muaj kev tiv thaiv tsis muaj kev cuam tshuam xov tolerances yog tshwj xeeb tshaj yog muaj nuj nqis nyob rau hauv precision engineering.

Automotive sector

Kev lag luam tsheb yog cov neeg siv khoom loj tshaj plaws ntawm Dacromet-coated fasteners. Cov tsheb tau raug cov dej ntsev, av noo, thiab kub hloov pauv. Cov ntawv thov tseem ceeb suav nrog:

• Chassis Cheebtsam: Ncua bolts, nres caliper pins, thiab kauj txuas txuas fasteners yuav tsum muaj kev tiv thaiv corrosion siab kom muaj kev nyab xeeb.
• Cav Systems: Lub tog raj kheej taub hau bolts, manifold studs, thiab roj lauj kaub screws tau txais txiaj ntsig los ntawm cov cua sov ua haujlwm thiab tiv thaiv cov khoom ntawm cov txheej.
• Sab nrauv Hardware: Qhov rooj hinges, daim iav mounts, thiab trim clips tswj kom zoo nkauj thiab ua haujlwm txawm tias raug huab cua.

Kev tsim kho thiab Infrastructure

Hauv kev tsim kho, fasteners feem ntau raug rau sab nraum zoov ntau xyoo lawm. Dacromet muab cov ntaub thaiv kev ruaj ntseg rau cov qauv kev sib txuas, cov ntsia hlau vov tsev, thiab cov façade anchors. Nws cov yeeb yaj kiab nyias ua kom ntseeg tau tias cov txiv ntseej thiab cov bolts tuaj yeem raug kaw kom nruj torque specifications yam tsis muaj kev cuam tshuam ntawm tuab galvanizing txheej.

Hluav taws xob thiab Electronics

Rau hluav taws xob enclosures thiab grounding hardware, conductivity thiab corrosion tiv thaiv yog ob qho tib si tseem ceeb. Txawm hais tias Dacromet tsis muaj qhov cuam tshuam zoo piv rau cov hlau liab qab, cov qauv tsim tshwj xeeb tuaj yeem hloov kho rau cov kev xav tau ntawm hluav taws xob txuas ntxiv hauv cov ntawv thov hauv av, muab kev tiv thaiv corrosion zoo dua li cov txheej txheem zinc plating.
