Technical Parameters & Material Selection Guide
High -purity graphite tsis yog ib qho khoom siv sib hloov. Xaiv cov qib raug yog nyob ntawm cov khoom siv kho tshuab, kev ua haujlwm kub, thiab kev sib kis- tswj cov cai.
Cov ntsiab lus tshauv & Purity txwv:Qhia meej qhov siab tshaj plaws uas tso cai rau cov hmoov tshauv thiab lub hom phiaj ntawm ib tus neeg hlau impurities (xws li Fe, Ni, V, Al, Ca) es tsis txhob cia siab rau cov ntawv purity generic.
Bulk Density & Porosity:Cov khoom ntim ntau dua tuaj yeem txhim kho cov neeg kho tshuab lub zog thiab txo cov pa permeability nyob rau hauv qhov hnyav thermal ib puag ncig.
Coefficient ntawm Thermal Expansion (CTE):Qhov tseem ceeb rau cov khoom uas raug thermal cycling sai, txo qis kev ntxhov siab sab hauv thiab micro-kev pheej hmoo tawg.
Grain Structure:Fine- cov qib isotropic cov qhab nia muab cov khoom siv lub cev zoo ib yam nyob rau hauv txhua qhov kev qhia, ua kom muaj kev ua tiav zoo tshaj plaws thiab kev coj tus cwj pwm zoo piv rau cov qauv extruded graphite.
Precision CNC Machining & Secondary Kev Kho Mob
Graphite yog cov khoom siv abrasive uas xav tau cov cuab yeej tshwj xeeb los tiv thaiv ntug chipping, micro- cracking, thiab subsurface puas.
Machining peev xwm
Complex contours, sib sib zog nqus hnab tshos, threaded qhov, precision slots, thiab zoo -pitch grooves raug tua rau ntawm nplooj siab carbon{1}}machining CNC chaw.
Purification Options
High-kub lub tshuab nqus tsev thermal kho nyob rau hauv cov roj halogen kom txo cov khoom seem ntawm cov hlau nplaum mus rau ultra- qhov pib qis.
Txheej Txheej
Optional silicon carbide (SiC) los yog pyrolytic carbon coatings siv qhov twg tshuaj tiv thaiv tiv thaiv reactive silicon vapors los yog yaj erosion yog teev.
Quality Assurance & Technical Documentation
Txhawm rau tshem tawm cov kev pheej hmoo ntawm kev xa mus, kev tsim khoom zoo raug soj ntsuam los ntawm kev ntsuas, kev cog lus pom zoo tshuaj xyuas cov qauv:
Dimensional Verification:100% los yog statistical sampling soj ntsuam siv calibrated CMM cov khoom tiv thaiv pom zoo 2D / 3D CAD cov ntaub ntawv.
Khoom siv Traceability:Ntau- tswj cov ntaub ntawv raw txuas ncaj qha rau cov ntaub ntawv txheeb xyuas cov neeg siv khoom.

Cov lus nug nquag
Q: Dab tsi graphite purity qib yog tus qauv rau semiconductor siv lead ua kev loj hlob?
A: Cov ntawv thov semiconductor feem ntau xav tau cov hmoov tshauv tswj hauv qab 5 ppm lossis 2 ppm, nyob ntawm cov neeg siv khoom siv lead ua tshwj xeeb- qauv purity. Ib txwm txhais cov kev txwv tsis pub muaj hlau tsis huv es tsis yog cia siab rau cov ntsiab lus dav dav.
Q: Cov graphite puas tuaj yeem tsim ncaj qha los ntawm cov neeg siv khoom kos duab?
A: Yog. Tag nrho cov khoom yog kev cai- tshuab raws li koj muab 2D engineering kos duab lossis 3D qauv, ua raws li koj qhov kev kam rau ua thiab qib khoom siv.
