Upfu hwegrafiti igrafiti yeupfu ine saizi dzakasiyana dzezvimedu, magadzirirwo uye huwandu hwekabhoni. Mhando dzakasiyana dzeupfu hwegrafiti dzinogadziriswa nenzira dzakasiyana dzekugadzira. Muminda yakasiyana yekugadzira maindasitiri, upfu hwegrafiti hune mashandisirwo akasiyana uye mabasa. Ndezvipi zvakanakira upfu hwegrafiti pakuputira?
1. Zvichibva pakukwira kwehupfu hwegrafiti, inogona kugadzirwa kuita machira akasiyana-siyana ekufambisa, machira anodzivirira kupisa kwakanyanya, zvinhu zvinodzivirira ngura, nezvimwewo.
2. Upfu hwegirafiti hunoshandiswa pakuputira hudiki, hune simba rekufambisa mvura, hunotsvedzerera pakuputira, uye hunogona kuomeswa mushure mekuputira. Firimu rekuputira haripfekwe kana richishandiswa, uye harina njodzi kune nharaunda, rakachena uye harina kusvibiswa, izvo zvinoita basa rakakosha mukugadzirwa kwekuputira.
3. Hudiki hwehupfu hwegirafiti hwekuputira huchaita kuti resistivity yekuputira ive shoma, izvo zvichaita kuti kuputira kuve nehuwandu hwakakura hwekushandiswa uye hupenyu hurefu hwebasa.
4. Kuputira girafiti nehupfu hwegirafiti kune conductivity yakanaka uye kunamira, uye inogona kubatanidzwa zvakanaka nenzvimbo dzakatsetseka dzakadai segirazi nepurasitiki, uye inogona kuchengetedza conductivity yayo yakanaka kunyangwe patembiricha ye300 degrees Celsius. Grafiti hupfu hwegirafiti hunogona kuita basa re conductivity, resistance high tembiricha uye resistance yekupfekwa.
Furuite Graphite inyanzvi yekugadzira upfu hwegrafiti. Kana muine hurongwa hwekutenga hune chekuita neupfu hwegrafiti, tinokugamuchirai kushanyira fekitori yedu kuti tikukurukurei.
