Purity siab Graphite Pwm


Khoom Nthuav dav

Cov kabmob sib xyaw ua ke pwm feem ntau yog ua los ntawm cov hlau. Txawm li cas los xij, los ntawm cov kev xav ntawm kev txiav txim siab pwm thiab lawv cov kev npaj siv cov hom pwm muaj qhov nyuaj rau noj cov duab nyuaj thiab ua haujlwm nrog cov ntaub ntawv sib xyaw. Qhov no yog tshwm sim ntawm qhov tsis sib xws thermal expansion coefficients ntawm cov pwm nws tus kheej thiab cov ntaub ntawv tso rau sab hauv. Yog li no, graphite tau tshwm sim los ua thawj qhov kev xaiv rau pwm ua vim nws lub cev xav tau thiab lub zog. Jitai muag ntau yam ntawm cov kev cai muaj siab purity graphite pwm uas tuaj yeem txo qhov kev lav tus nqe rau peb cov neeg siv khoom.

 

Graphite yog ib daim ntawv sib zog ntawm cov khoom siv roj carbon nrog cov yam ntxwv hauv qab no:

1. Kev ua kom zoo thermal thiab hluav taws xob zoo;

2. Tshaj tawm mus rau tshuaj lom neeg corrosion thiab tsis hnov ​​mob yooj yim nrog ntau hom hlau

3. Tsawg thermal nthuav coefficient thiab zoo thermal stability

4. Muaj roj nplua nyeem zoo thiab hnav tsis kam

5. Ua tau zoo nyob rau hauv huab cua sov (feem ntau tooj liab hlau matrix sintering kub siab dua 800 ℃). Lub zog nce ntxiv nrog rau qhov nce ntawm kub

6. Kev ua haujlwm zoo hauv lub tshuab, tuaj yeem siv rau pwm txhaj nrog cov duab ua haujlwm nyuaj thiab hauv cov xwm txheej uas muaj qhov xav tau siab.

1.Ued rau kev nruam thiab ib nrab txuas nruam ntawm cov hlau tsis sib haum. Vim tias nws cov zoo thermal conductivity thiab nws tus kheej lubricating zoo ntawm cov khoom, qhov loj ntawm lub ingot nyob qis qis yog qhov tseeb, qhov saum npoo tseem du, thiab nws cov qauv crystalline nyob ruaj khov txawm tias tom qab ntau firings. Qhov no tso cai rau kev nce casting nrawm ntxiv, kom ntseeg tau tias cov txheej txheem txuas ntxiv tuaj yeem pib tam sim ntawd. Qhov no zoo heev txhim kho cov paib nqi thiab cov khoom lag luam zoo.

2. Cov pwm tsim rau siab ua: Cov Artite graphite tau ua tiav zoo rau kev siv lub tshuab ua kom siab ntawm cov hlau tsis muaj hlau. Piv txwv li, zinc alloy thiab tooj liab alloy castings tsim nrog siab casting pwm ntawm cov khoom cua graphite feem ntau siv hauv tsheb tsheb.

3. Cov duab pwm tsim rau centrifugal casting: Cov duab pwm loj muaj peev xwm ua tiav ntawm kev siv lub tshuab luam tawm me me. Cov tuam txhab Asmeskas tau siv cov duab graphite pwm nrog lub ntsej muag tuab tshaj li 25mm mus rau centrifugally nrum tooj daj, bushings, thiab tes tsho.

4. Cov nias pwm kub: Cov duab graphite siv nyob rau hauv kub nias pwm muaj ob tus yam ntxwv rau siab sintering ntawm cemented carbides:

A) Yog hais tias qhov ntsuas kub thaum lub sijhawm nias nce siab txog 1350 txog 1450 ℃, qhov ntsuas qhov yuav tsum tau tuaj yeem txo mus rau 1/10 ntawm yam yuav xav tau yog tias pwm txias. 

B) Kev nias thiab cua sov yog ua tib lub sijhawm, thiab lub cev ntom ntom ntaws tuaj yeem tau txais tom qab tsuas yog lub sijhawm luv luv ntawm kev ua txhaum.

5. Pwm rau iav moulding: Cov khoom siv Graphite tau dhau los ua qhov tsis tuaj yeem ua pwm rau kev ua haujlwm nrog iav. Nws tuaj yeem siv los ua pwm rau iav cov raj, lauj tshib, funnels thiab ntau hom ntawm lwm daim ntawv.

6. Sintering pwm thiab lwm cov pob zeb diamond sintering pwm: Vim tias lub tshav kub tsis tshua muaj nthuav dav ntawm cov khoom cua graphite, sintering pwm thiab kab thaiv rau transistors tuaj yeem tsim. Nws yog tam sim no dav siv thiab tau dhau los ua ib qho khoom siv tsis tseem ceeb rau kev tsim kho ntawm kev lag luam semiconductor.
