Graphite ndi chinthu chopangidwa ndi zinthu za kaboni. Kapangidwe kake ka atomu kamakonzedwa ngati chisa cha hexagonal. Ma electron atatu mwa anayi omwe ali kunja kwa atomu amapanga ma covalent bond amphamvu komanso okhazikika ndi ma electron a atomic nuclei oyandikana nawo, ndipo atomu yowonjezerayo imatha kuyenda momasuka pa netiweki, zomwe zimapangitsa kuti ikhale ngati conductivity yamagetsi.
Malangizo Ogwiritsira Ntchito Ma Electrode a Graphite
1. Yosanyowa - Pewani mvula, madzi kapena chinyezi. Umitsani musanagwiritse ntchito.
2. Kuletsa kugundana - Gwirani mosamala kuti mupewe kuwonongeka chifukwa cha kugundana ndi kugundana panthawi yoyendetsa.
3. Kuteteza ming'alu - Mukamangirira elekitirodi ndi maboliti, samalani ndi mphamvu yomwe imagwiritsidwa ntchito kuti mupewe ming'alu chifukwa cha mphamvu.
4. Choletsa kusweka - Graphite ndi yofooka, makamaka pa ma electrode ang'onoang'ono, opapatiza komanso aatali, omwe amatha kusweka mosavuta chifukwa cha mphamvu yakunja.
5. Zipangizo zosagwira fumbi - Zipangizo zosagwira fumbi ziyenera kuyikidwa panthawi yokonza makina kuti zichepetse kuwononga thanzi la anthu komanso chilengedwe.
6. Kupewa utsi - Makina opangira magetsi amatha kutulutsa utsi wambiri, choncho zipangizo zopumira mpweya zimafunika.
7. Kupewa kutayidwa kwa kaboni – Graphite imakonda kutayidwa kaboni ikatulutsidwa. Pakukonza, ndikofunikira kuyang'anira bwino momwe imagwirira ntchito.
Kuyerekeza kwa Makina Otulutsa Magetsi a Graphite ndi Red Copper Electrodes (Kufunika luso lathunthu)
1. Kugwira bwino ntchito yokonza makina: Kukana kudula ndi 1/4 ya mkuwa, ndipo kugwira bwino ntchito yokonza ndi kawiri kapena katatu kuposa mkuwa.
2. Electrode ndi yosavuta kupukuta: Kukonza pamwamba ndi kosavuta komanso kopanda ma burrs: N'kosavuta kudula pamanja. Kukonza pamwamba mosavuta ndi sandpaper ndikokwanira, zomwe zimapewa kwambiri kusokonekera kwa mawonekedwe komwe kumachitika chifukwa cha mphamvu yakunja pa mawonekedwe ndi kukula kwa electrode.
3. Kugwiritsa ntchito ma electrode ochepa: Ili ndi mphamvu yabwino yoyendetsera magetsi komanso mphamvu yochepa yolimbana ndi mkuwa, yomwe ndi 1/3 mpaka 1/5. Pa nthawi yokonza zinthu mopanda mphamvu, imatha kutulutsa madzi mosavuta.
4. Liwiro lotulutsa madzi mwachangu: Liwiro lotulutsa madzi ndi lowirikiza kawiri mpaka katatu kuposa la mkuwa. Mpata wogwiritsa ntchito makina okhwima ukhoza kufika pa 0.5 mpaka 0.8 mm, ndipo mphamvu yamagetsi imatha kufika pa 240A. Kuwonongeka kwa ma electrode kumakhala kochepa ngati kumagwiritsidwa ntchito nthawi zambiri kwa zaka 10 mpaka 120.
5. Kulemera kopepuka: Ndi mphamvu yokoka ya 1.7 mpaka 1.9, yomwe ndi 1/5 ya mkuwa, imatha kuchepetsa kwambiri kulemera kwa ma electrode akuluakulu, kuchepetsa katundu pa zida zamakina komanso kuvutika kuyika ndi kusintha ndi manja.
6. Kukana kutentha kwambiri: Kutentha kwa sublimation ndi 3650℃. Pa kutentha kwambiri, electrode sifewa, kupewa vuto la kusintha kwa ma workpieces okhala ndi makoma owonda.
7. Kusintha kwa ma electrode ang'onoang'ono: Kuchuluka kwa kutentha komwe kumawonjezeka ndi kochepera 6 ctex10-6 /℃, komwe ndi 1/4 yokha ya mkuwa, zomwe zimapangitsa kuti kulondola kwa kutulutsa madzi kukhale kolondola.
8. Mapangidwe osiyanasiyana a ma electrode: Ma electrode a Graphite ndi osavuta kutsuka ngodya. Ma workpiece omwe nthawi zambiri amafunikira ma electrode angapo amatha kupangidwa kukhala electrode imodzi yonse, kupititsa patsogolo kulondola kwa nkhungu ndikuchepetsa nthawi yotulutsa.
A. Liwiro la graphite pakupanga zinthu ndi lachangu kuposa la mkuwa. Pogwiritsa ntchito moyenera, limathamanga kawiri mpaka kasanu kuposa mkuwa.
B. Palibe chifukwa chogwiritsa ntchito maola ambiri pantchito pochotsa zinthu zonyansa monga momwe mkuwa umachitira;
C. Graphite imatuluka mwachangu, yomwe ndi nthawi 1.5 mpaka 3 kuposa mkuwa mumagetsi ovuta.
D. Ma electrode a grafiti sawonongeka kwambiri, zomwe zimachepetsa kugwiritsa ntchito ma electrode
E. Mtengo wake ndi wokhazikika ndipo sukhudzidwa kwambiri ndi kusinthasintha kwa mitengo pamsika
F. Imatha kupirira kutentha kwambiri ndipo imakhalabe yosasinthika panthawi yokonza magetsi
G. Ili ndi coefficient yaying'ono ya kutentha komanso kulondola kwambiri kwa nkhungu
H. Yopepuka kulemera, imatha kukwaniritsa zofunikira za nkhungu zazikulu komanso zovuta
Pamwamba pake ndi posavuta kukonza ndipo n'zosavuta kupeza malo oyenera okonzera
