Upfu hwegrafiti ndiyo goridhe mumunda wemaindasitiri, uye hune basa guru muminda yakawanda. Kare, zvaiwanzotaurwa kuti upfu hwegrafiti ndiyo mhinduro yakanakisisa yekudzivirira ngura yemidziyo, uye vatengi vazhinji havazivi chikonzero. Nhasi, mupepeti weFuruite Graphite achatsanangura zvakadzama kuti sei uchitaura izvi:
Kushanda zvakanaka kweupfu hwegirafiti kunoita kuti ive mhinduro yakanakisisa yekudzivirira ngura yemidziyo.
1. Haipindi pakupisa kwakanyanya. Kushandiswa kwekupisa kwegrafiti kunoenderana nerudzi rwezvinhu zvinopinda mudumbu, zvakaita sephenolic resin yakapinzwa graphite inogona kumira 170-200℃, uye kana huwandu hwakakodzera hwesilicone resin yakapinzwa graphite ikaiswa, inogona kumira 350℃. Kana phosphoric acid ikaiswa pacarbon negraphite, kuramba kwecarbon negraphite oxidation kunogona kuvandudzwa, uye tembiricha chaiyo yekushanda inogona kuwedzera.
2. Kufambisa kwekupisa kwakanaka kwazvo. Upfu hwegirafiti hunewo kutenderera kwakanaka kwekupisa, uko kwakakwira kupfuura kwesimbi pakati pezvinhu zvisiri zvesimbi, zvichitanga pakati pezvinhu zvisiri zvesimbi. Kufambisa kwekupisa kwakapetwa kaviri kupfuura simbi yekabhoni uye kanomwe kupfuura simbi isina ngura. Saka, yakakodzera michina yekufambisa kupisa.
3. Kudzivirira ngura zvakanyanya. Mhando dzese dzekabhoni negrafiti dzinodzivirira ngura zvakanyanya pahuwandu hwese hwehydrochloric acid, phosphoric acid nehydrofluoric acid, kusanganisira fluorine-containing media. Tembiricha yekushandisa i350℃-400℃, kureva tembiricha iyo kabhoni negrafiti zvinotanga kuoxida.
4. Pamusoro payo hapasi nyore kugadzika. "Kubatana" kuripo pakati peupfu hwegirafiti nemidziyo yakawanda yemagetsi kudiki kwazvo, saka ivhu harina kuoma kunamira pamusoro. Kunyanya pamidziyo yekudziyisa mvura nemidziyo 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 nekutungamira fekitori yedu.
