High Purity Graphite Pwm
Ib txwm cov pwm sib xyaw feem ntau yog ua los ntawm cov hlau.Txawm li cas los xij, los ntawm kev xav ntawm kev tsim pwm thiab lawv qhov kev npaj siv cov pwm no muaj kev nyuaj rau kev siv cov duab nyuaj thiab ua haujlwm nrog cov khoom sib xyaw.Qhov no yog qhov tshwm sim ntawm incompatible thermal expansion coefficients ntawm pwm nws tus kheej thiab cov khoom nyob rau hauv.Yog li ntawd, graphite tau tshwm sim los ua thawj qhov kev xaiv rau pwm ua vim nws xav tau lub cev thiab tshuaj lom neeg.Jitai muag ntau yam kev cai siab purity graphite pwm uas tuaj yeem txo tus nqi ib feem rau peb cov neeg siv khoom.
Graphite yog ib daim ntawv crystalline ntawm cov khoom carbon nrog cov yam ntxwv hauv qab no:
1. Zoo heev thermal thiab hluav taws xob conductivity;
2. Cov tshuaj tiv thaiv corrosion thiab tsis hnov mob yooj yim nrog ntau yam hlau
3. Tsawg thermal expansion coefficient thiab zoo thermal stability
4. Zoo tagnrho lubrication thiab hnav tsis kam
5. Ua tau zoo nyob rau hauv huab cua kub (feem ntau tooj liab hlau matrix sintering kub siab tshaj 800 ℃).Lub zog nce concurrently nrog qhov nce ntawm qhov kub thiab txias
6. Zoo machining kev ua tau zoo, tuaj yeem siv rau cov pwm nrog cov duab nyuaj thiab nyob rau hauv cov xwm txheej uas yuav tsum muaj siab precision.
1.Siv rau nruam thiab semi-nruab nruam casting ntawm non-ferrous hlau.Vim nws cov thermal conductivity zoo thiab nws tus kheej-lubricating zoo ntawm cov khoom, qhov loj ntawm lub ingot nyob twj ywm raug, qhov nto tseem du, thiab nws cov crystalline qauv nyob twj ywm uniform txawm tias tom qab ntau firings.Qhov no tso cai rau kom nce nrawm nrawm, kom ntseeg tau tias cov txheej txheem tom ntej tuaj yeem pib tam sim tom qab.Qhov no zoo heev txhim kho tus nqi tawm los thiab cov khoom zoo.
2. Pwm rau siab casting: Artificial graphite tau ntse siv rau siab casting ntawm non-ferrous hlau.Piv txwv li, zinc alloy thiab tooj liab alloy castings tsim nrog lub siab casting pwm ntawm cov khoom siv graphite yog nquag siv hauv tsheb.
3. Graphite pwm rau centrifugal casting: Graphite pwm tau zoo siv hauv centrifugal casting.Cov tuam txhab Asmeskas tau siv cov khoom siv graphite pwm nrog cov phab ntsa tuab ntawm ntau dua 25mm rau centrifugally nrum bronze bushings, bushings, thiab tes tsho.
4. Kub nias pwm: Cov khoom siv graphite siv hauv kub nias pwm muaj ob yam ntxwv rau siab sintering ntawm cemented carbides:
A) Yog hais tias qhov kub thiab txias thaum lub sij hawm nias yog nce mus rau 1350 mus rau 1450 ℃, lub siab yuav tsum tau txo mus rau 1/10th ntawm qhov yuav tsum tau yog tias pwm txias.
B) Nias thiab cua sov yog ua tiav ib txhij, thiab lub cev ntom ntom sintered tuaj yeem tau txais tom qab tsuas yog lub sijhawm luv ntawm sintering.
5. Pwm rau iav molding: cov khoom siv graphite tau dhau los ua cov khoom pwm tsis tseem ceeb rau kev ua haujlwm nrog iav.Nws tuaj yeem siv los ua cov pwm rau iav raj, lub luj tshib, funnels thiab ntau hom.
6. Sintering pwm thiab lwm yam pob zeb diamond sintering pwm: Vim tias tsis tshua muaj thermal expansion ntawm cov khoom graphite, sintering pwm thiab brackets rau transistors tuaj yeem tsim.Tam sim no nws tau siv dav thiab tau dhau los ua cov khoom siv tsis tseem ceeb rau kev txhim kho kev lag luam semiconductor.
Kev ua tau zoo sib piv ntawm cov khoom siv pwm ua cov khoom siv thiab cov khoom sib xyaw
