Cov ncauj lus kom ntxaws kev tsim cov txheej txheem ntawm tsheb nres nres
Raws li kev nyab xeeb ntawm kev nyab xeeb ntawm cov khoom siv braking, nres lub ncoo ntau lawm: thermodynamics, thiab precision machining thev naus laus zis. Hauv qab no yog kev txheeb xyuas ntawm cov haujlwm niaj hnub tsim rau kev ua haujlwm tseem ceeb SEMI-METALLIC nres PADS.
I. Raw khoom npaj
1. Cov qauv tsim qauv
Raws li kev ua tau zoo xws li sib txhuam coefficient ({}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}.
- txhawb cov hwj chim: Steel fibers (30% -50% muaj pes tsawg leeg), aramid fibers
- Kev sib txhuam Convifiers:Graphite (thermal conductivity), barite (suab nrov txo)
- Binders:Hloov cov phenolic resin (qhov kub siab tiv thaiv)
- Fillers:Tooj liab hmoov (txhim kho thermal conductivity), alumina (hardness hloov kho)
2. Kev kho mob ua ntej
- Steel fibers yauv spedgo phosphate nto kev kho kom txhim kho cov nplaum adhesion.
- Cov lus graphite yog pulverized mus rau 10-50 μm ntawm Dav Hlau Milling.
Ii. Sib xyaw & Tsim Ua Ntej
1. 3D sib xyaw
Cov khoom siv-ntiaj chaw ua ke xyaw 15-20 raw rau 30 feeb nyob rau hauv lub tshuab nqus tsev ntawm 60 degree los tiv thaiv cov resin ua ntej kho ua ntej. Sib tov sib xyaw yuav tsum tau tshaj 99.5%.
2. Txias nias
Cov sib tov yog moulded nyob rau hauv 20-30 MPA siab rau hauv cov ntaub ntawv ua ntej nrog qhov ntom ntom ntawm 2.4-2.7 g / cm³. Qhov kev ua tiav theem no ~ 70% cov qauv txheej txheem rau kev nias kub txuas ntxiv.
III. Cov Xovxwm Kub Moulding
1. Kev kho kub siab
350-}} Tuj Hydraulic Xovxwm Siv 160-180 Degree Kub Thiab 60-100 Mpawm Siab Rau 5-8 feeb. Phenolic Resin ua cov 3D hla txuas network, thaum tooj liab fibers dlhos los ntawm kev ua kom zoo ntawm kev ua kom zoo.
2. Gradient Kub Tswj
Pwm Zones tau sib txawv rhuab: 180 kawm tiav ntawm lub chaw rau kev kho kom sai thiab 170 degree ntawm cov npoo kom tiv thaiv scorching. Qhov kub nyhiab yog txwv rau ± 2 degree.
IV. Kev Kho Cua Sov & Kev Ua Haujlwm Tom Qab
1. Stepwise sintering
Qhov chaw taws cua sov xws li peb ntu:
- 150 degree / 2h: kev ntxhov siab nyem
{{0 {}} degree / 4h: ua tiav resin kho
{{0 {0}} degree / 1h: thermal ruaj khov txhim kho
2. Precision sib tsoo
CNC SIB TSOO MACHINE Txheej Txheej Txheej Txheem Txhuas Sib Nqus:
- Sib tsoo ntxhib: {{{{1} grit log tawm 0. 2 hli dhau
- Zoo sib tsoo: {400- grit log ua tau kom ua tiav nplaim roughness ra tsawg dua lossis sib npaug rau 3.2 μm
- Chamfering: R1.5 mm ntug rolving los tiv thaiv chipping
V. Deg Kev Kho Mob & Sib Dhos
1. Txheej
- Primer: Epoxy Resin txheej tiv taus txog 800 degree
- Topcoat: Kev kub-kub-resistant liab / xiav cim xim (50-80 μm tuab)
2. Shim sib dhos
Laser welding bonds 0.3 mm stainless steel anti-noise shims to backplates, requiring shear strength >15 MPA. Cov Rooj Sib Tham Jougo 2 plhom kev co mus rau kev siv tau.
VI. Kev Muaj Peev Xwm Zoo
1. Kev Sib Tw Ua Haujlwm Kuaj
Inertia Dynamometer Toolmom:
- Kev txhuam hniav coefficient<10% between 100–350°C
- Tsawg dua lossis sib npaug rau 15% lwj tom qab 50 sib law liag braking cycles
2. Cov tsis yog-kev sim ua txhaum
- Kev tshuaj xyuas ultrasonic: kuaj pom sab hauv voids thiab delamination
- X-Ray Kev Ntsuas: Kev txheeb xyuas tooj liab fiber ntau cov kev faib tawm
3. Kev Siv Txoj Kev
Kev ntsuas lub tsheb tiag tiag suav nrog:
- 30} Nres nres thaum muaj xwm ceev los ntawm 100 km / h rau sawv ntsug
{{0 {0}} feeb txuas ntxiv mus braking rau ntev kawg hauv roob nqes hav
Cov Hluav Taws Xob
- Laser Cladding:{{0 {0}}. 1 hli alloy txheej ntawm backplates txhim kho kev coj tsis kam los ntawm 3 ×
- AI Kos Duab:Kev kawm sib sib zog qhia cov micro-tawg nrog 99.98% tseeb
- Kev tsim khoom ntsuab:Cov dej pleev cov dej ua haujlwm txo cov pa hluav taws xob voc emissions los ntawm 90%
Los ntawm cov raw cov khoom siv ua tiav kom tiav cov khoom lag luam, nres ncoo tsim zoo li lub ntsej muag zoo ib yam. Txhua {{1 {1}}. 01 mm lub mi kev zam tswj kev tswj hwm kev nyab xeeb tsav tsheb. Nrog kev tsim khoom ntse ntse ntxiv, kev lag luam ib txwm muaj kev hloov mus rau xoom-tsis zoo, siab traceable cov kev tsim digital.
