Boron Nitride Txheej Txheem yog tsuas yog siv rau pwm tso tawm hauv kev lag luam txhuas

Hauv kev ua yeeb yaj kiab, extrusion thiab tuag Casting zus tau tej yam kev tawm dag zog, pwm tawm tau qhov kev sib tw tseem ceeb cuam tshuam thiab cov khoom lag luam zoo. Cov tshuaj tso tawm cov neeg sawv cev (xws li graphite, silicone roj, thiab cov pa roj ntsha, thiab cov tshuaj lom neeg lub siab, kev xaiv ntawm pwm tawm thev naus laus zis.
I. Qhov zoo ntawm Boron Nitride Castings rau pwm tso
1. Ultra-high temperature stability (temperature resistance >1500 degree)
Boron nitride coating will not oxidize or decompose during aluminum alloy die casting (600-800℃) and fusion casting (1200℃+), which is far better than graphite (>500 degree oxidation) thiab silicone pwm tawm tus neeg sawv cev (<300℃ failure).
Cov ntaub ntawv: Tom qab lub Hoobkas txiav Hoobkas tau txais BN txheej BN txheej, lub pwm lub neej tau txuas ntxiv los ntawm 3 zaug.
2. Cov coefficient ntawm kev sib txhuam (μ<0.2)
Cov txheej txheem txheej txheem ntawm H-BN muab graphite-zoo li lubricity-zoo li lubricity tsis muaj kev pheej hmoo ntawm cov carbon paug.
Nws txo cov nplaum ntawm txhuas ua kua rau cov pwm thiab txo qhov kev tso tawm dag zog tawm los ntawm {}}%.
3. Xoom pa paug & kev tu neeg yooj yim
BN tsis muaj kev cuam tshuam nrog txhuas, zam kev impurities ntawm casting saum npoo (piv txwv li cov seem ntawm cov pa tawm tuaj pwm.
Cov txheej tuaj yeem siv tau rau lub sijhawm ntev, txo lub downtime ntawm cov tshuaj tua hluav taws xob ntau ntawm cov neeg sawv cev pwm.
Raug Daim Ntawv Teev Lus
1. Aluminium Alloy Tuag Casting (Qhov Chaw Automotive, 3C plhaub)
Qhov Teeb Meem: High-Silicon Alloy Alloy (xws li ADC12) yog ib qho yooj yim los lo rau pwm tawm ntawm cov neeg sawv cev tso tshuaj tiv thaiv ib zaug txhua {2}} Mev lub sijhawm.
Kev daws: Lub Pwm saum npoo yog coated nrog bn txheej ({{{}} μm), uas tuaj yeem siv txuas ntxiv rau ntau tshaj 200 tuag.
2. Kub Extrusion ntawm Aluminium Profiles
Teeb meem: hnav thiab kua muag ntawm extrusion barrel thiab tuag ua rau cov khawb rau ntawm qhov chaw profile.
Kev daws: Txais BN-raws li lubrication txheej kom txo kev sib txhuam thiab txhim kho saum npoo tiav (ra<0.8μm).
3. Aluminium alloy fusion casting (tiaj tus ingot, round bar)
Qhov Teeb Meem: Txhuas Kev Ua Poj Ntsuam Ntawm Sab Hauv Phab Ntsa Ntawm Crystallizer, Ua rau Cryregation, Ua rau Cryregation CryRegation Thiab Nrib pleb.
Kev daws: BN txheej hloov graphite txheej kom txo ingot deg tej yam tsis xws luag thiab nce tawm los ntawm 15%.
Boron Nitride Txheej yog rov kho cov txheej txheem kev tso tawm los ntawm nws cov khoom muaj kuab paug, hluav taws xob tuag, hluav taws xob tuag casting) kom pom muaj peev xwm zoo. Nrog kev nce qib ntawm cov kev ntsuas loj loj thiab cov thev naus laus zis thev naus laus zis, yuav tsum ua cov kev daws teeb meem zoo rau cov tshuaj tso tawm.
