Upfu hwegirafiti ndiyo goridhe mumunda wemaindasitiri uye hune basa guru muminda yakawanda. Ndaiwanzonzwa shoko risati rasvika rekuti upfu hwegirafiti ndiyo mhinduro yakanakisisa yekudzivirira ngura yemidziyo. Vatengi vazhinji havanzwisisi chikonzero. Nhasi, mupepeti wegirafiti yeFuruite ndewemunhu wese. Tsanangura zvakadzama kuti sei ichidaro:
Hunhu hwepamusoro hweupfu hwegirafiti hunoita kuti ikurumidze kuva mhinduro yakanakisisa yekudzivirira ngura yemidziyo.
1. Haina simba pakupisa kwakanyanya. Kushandiswa kwekupisa kweupfu hwegrafiti kunoenderana nemhando yezvinhu zvinoisa mushonga. Semuenzaniso, graphite yakaisirwa phenolic inogona kumira 170-200 ° C. Kana huwandu hwakakodzera hwesilicone resin hukawedzerwa kugrafiti yakaisirwa mushonga, inogona kumira kusvika 350 ° C; kana phosphoric acid yakaiswa pacarbon negraphite, inogona kumira. Kuti ivandudze kusimba kwecarbon negraphite, tembiricha chaiyo yekushanda inogona kuwedzera.
2. Kufambisa kwekupisa kwakanaka kwazvo. Upfu hwegirafiti hunewo kutenderera kwekupisa kwakanaka. Chinhu chisiri chesimbi chine kutenderera kwekupisa kwakanyanya kupfuura kwesimbi, chiri pachinzvimbo chekutanga muzvinhu zvisiri zvesimbi. Kufambisa kwekupisa kwakapetwa kaviri kupfuura simbi yekabhoni uye kanomwe kupfuura simbi isina ngura. Saka, yakakodzera kushandiswa mumidziyo yekufambisa kupisa.
3. Kudzivirira ngura zvakanyanya. Mhando dzakasiyana dzekabhoni negrafiti dzinodzivirira ngura zvakanyanya pahuwandu hwese hwehydrochloric acid, phosphoric acid uye hydrofluoric acid, kusanganisira fluorine-containing media.
4. Pamusoro payo hapasi nyore kugadzika. "Kubatana" kuripo pakati peupfu hwegrafiti nemidziyo yakawanda yemagetsi kudiki kwazvo, saka ivhu harina kuoma kunamira pamusoro. Inonyanya kushandiswa mumidziyo yekudziyisa mvura uye michina yekusimbisa makristaro.
Tsananguro iri pamusoro apa inogona kukupa kunzwisisa kwakadzama kweupfu hwegrafiti. Qingdao Furuite Graphite inonyanya kugadzirisa nekugadzira upfu hwegrafiti, flake graphite nezvimwe zvigadzirwa. Munobvumirwa kushanyira fekitori kuti muwane gwara.
