Cov yam ntxwv ntawm peb graphip electrode

Cov yam ntxwv ntawm pebGraph kaw electrode:

1. Cov nqi ruaj khov thiab tsim nyog:

Tus nqi ntawm graphite cov ntaub tsuas yog yuav tsum 15% ntawm tib lub ntim ntawm tooj liab electrode. Tam sim no, graphite tau dhau los ua cov khoom siv nrov rau EDM daim ntawv thov, nrog tus nqi qis thiab ruaj khov piv rau graphite cov ntaub ntawv.

1. Yooj yim txiav thiab ua
2. 4. Lub teeb ci thiab qis ntom ntom
3. Qhov ceev ntawm graphite feem ntau yog 1.7-1.9g / cm3 (tooj liab yog 4-5 zaug uas ntawm graphite). Piv rau cov luam ntawv tooj liab, graphite cov hluav taws xob yuav txo cov neeg siv khoom siv lub sijhawm no. Nws yog qhov tsim nyog rau kev thov cov pwm loj.
4. 5. Cov Khoom Zoo
5. Piv rau cov ntaub ntawv hlau, cov ntim ntawm graphite yog tsim kom muaj tsawg. Nws muaj kev ua haujlwm zoo heev.
6. 6. Tsev nyhuv bonding
7. Gravel number case yuav raug sib raug zoo los ntawm cov nplaum, uas txuag lub sijhawm thiab cov nqi khoom.
8. 7. Ntau Tshaj Plaws
9. Qhov tiv taus (ER) txiav txim siab cov khoom tawm tsam ntawm cov khoom uas ntws ntawm tam sim no. Ib qho qis dua kev siv tau txhais tau hais tias.

Graphite muaj cov khoom siv tshuab zoo heev. Lub machining ceev ntawm graphite electrodes yog 2-3 zaug siab dua li ntawd ntawm cov ntawv tooj liab hluav taws xob. Nyob rau tib lub sijhawm, tsis tas yuav txhawj txog burrs tom qab kev ua tiav.

3. Tsawg Thermal nthuav tawm coefficient

Lub ntsiab lus melting ntawm tooj liab yog 1080 ℃, thaum lub CTE ntawm graphite tsuas yog 1/30 ntawm tooj liab nyob rau 3650 ℃. Nws muaj kev ua tau ruaj khov heev txawm tias thaum sov sov. Txawm nyob hauv kev ua cov pob zeb platinum, graphite hluav taws xob muaj qhov zoo.
