1. Indasitiri yesimbi
Muindasitiri yesimbi, upfu hwegirafiti yechisikigo hunogona kushandiswa kugadzira zvinhu zvinoramba kushanda zvakaita sechidhinha chemagnesium carbon uye chidhinha chealuminium carbon nekuda kwekusagadzikana kwayo mukugadzirwa kwesimbi. Upfu hwegirafiti yechisikigo hunogona kushandiswa seelectrode yekugadzira simbi, asi electrode yakagadzirwa nehupfu hwegirafiti yechisikigo inonetsa kushandiswa muchoto chemagetsi chekugadzira simbi.
2. Indasitiri yemichina
Muindasitiri yemakanika, zvinhu zvegrafiti zvinowanzo shandiswa sezvinhu zvinodzivirira kupera uye zvinozora mafuta. Chinhu chekutanga chekugadzira graphite inogona kuwedzerwa igrafiti ine kabhoni yakawanda, uye zvimwe zvinhu zvemakemikari zvakaita sesulfuric acid yakakangwa (inopfuura 98%), hydrogen peroxide (inopfuura 28%), potassium permanganate nezvimwe zvinoshandiswa mumaindasitiri. Matanho akajairika ekugadzirira ndeaya anotevera: pakupisa kwakakodzera, huwandu hwakasiyana hwehydrogen peroxide solution, natural flake graphite uye concentrated sulfuric acid zvinowedzerwa munzira dzakasiyana, uye zvinogadziriswa kwenguva yakati pasi pekukanganiswa nguva dzose, zvozogezwa kusvika pakuparadzaniswa kwepakati, kupera mvura mumuviri uye kuomesa vacuum pa60 ℃. Natural graphite powder ine mafuta akanaka uye inowanzoshandiswa sechinhu chinowedzera mumafuta ekuzora. Pakutakura corrosive medium, piston rings, sealing rings uye mabearings akagadzirwa neartificial graphite powder anoshandiswa zvakanyanya, pasina kuwedzera mafuta ekuzora pakushanda. Natural graphite powder uye polymer resin composites zvinogonawo kushandiswa muminda iri pamusoro, asi resistance yekuzora haina kunaka seartificial graphite powder.
3. Indasitiri yemakemikari
Upfu hwegrafiti hwekugadzira hune hunhu hwekudzivirira ngura, kufambisa zvakanaka kwekupisa, kuyerera kwakaderera, uye hunoshandiswa zvakanyanya muindasitiri yemakemikari kugadzira chinoshandiswa kupisa, tangi rekuita, shongwe yekunyudza, firita nezvimwe zvishandiso. Upfu hwegirafiti hwechisikigo uye polymer resin composite zvinhu zvinogonawo kushandiswa muminda iri pamusoro, asi kufambisa kwekupisa, kudzivirira ngura hakuna kunaka seupfu hwegirafiti hwekugadzira.
Nekuvandudzwa kwetekinoroji yekutsvagisa, mukana wekushandiswa kweupfu hwegrafiti hwekugadzira haugone kuyerwa. Parizvino, kushandisa graphite yechisikigo sezvinhu zvisina kugadzirwa kugadzira zvigadzirwa zvegrafiti zvekugadzira kunogona kuonekwa seimwe yenzira dzakakosha dzekuwedzera munda wekushandisa graphite yechisikigo. Upfu hwegrafiti yechisikigo hwave huchishandiswa sezvinhu zvinobatsira mukugadzira upfu hwegrafiti hwekugadzira, asi hazvina kukwana kugadzira zvigadzirwa zvegrafiti zvekugadzira neupfu hwegrafiti yechisikigo sezvinhu zvikuru zvisina kugadzirwa. Nzira yakanakisa yekuzadzisa chinangwa ichi ndeyekushandisa zvizere chimiro nehunhu hweupfu hwegrafiti yechisikigo, uye kugadzira zvigadzirwa zvegrafiti zvekugadzira zvine chimiro chakakosha, mashandiro uye kushandiswa netekinoroji yakakodzera, nzira uye nzira.
