Iimpawu zokwandiswa kwe-graphite flake enokwandiswa zahlukile kwezinye ii-expansion agents. Xa ifudunyezwa ukuya kubushushu obuthile, i-graphite enokwandiswa iqala ukwanda ngenxa yokubola kwee-compounds ezibanjwe kwi-interlayer lattice, ebizwa ngokuba yi-initial expansion temperature. Iyanda ngokupheleleyo kwi-1000℃ kwaye ifikelele kwi-volume yayo ephezulu. I-volume eyongeziweyo inokufikelela ngaphezulu kwamaxesha angama-200 kwi-volume yokuqala, kwaye i-graphite eyongeziweyo ibizwa ngokuba yi-expanded graphite okanye i-graphite worm, etshintsha ukusuka kwi-original scaly shape ukuya kwi-worm shape enobunzima obuphantsi, okwenza umaleko we-thermal insulation olungileyo kakhulu. I-graphite eyongeziweyo ayisiyo kuphela umthombo wekhabhoni kwinkqubo yokwandiswa, kodwa ikwangumaleko we-insulation, onokukhusela ubushushu ngempumelelo. Ineempawu zesantya sokukhululwa kobushushu esiphantsi, ukulahleka okuncinci kobunzima kunye nomsi omncinci oveliswa emlilweni. Ngoko ke zeziphi iimpawu ze-graphite eyongeziweyo emva kokuba ifudunyezwe kwi-graphite eyongeziweyo? Nantsi umhleli ukuze ayichaze ngokweenkcukacha:
1, ukumelana noxinzelelo oluqinileyo, ukuguquguquka, i-plasticity kunye nokuzithambisa;
2. Ukumelana nobushushu obuphezulu kakhulu nobuphantsi, ukumelana nokugqwala kunye nokumelana nemitha;
3. Iimpawu ezinamandla zenyikima;
4. Ukuqhuba okuphezulu kakhulu;
5. Iimpawu ezinamandla zokulwa nokwaluphala kunye nokungaguquki;
6. Iyakwazi ukumelana nokunyibilika nokungena kweentsimbi ezahlukeneyo;
7. Ayinatyhefu, ayinayo i-carcinogen, kwaye ayinabungozi kwindalo esingqongileyo.
Ukwandiswa kwegrafiti enokwandiswa kunokunciphisa ukuhanjiswa kobushushu bezinto kwaye kufezekise isiphumo sokungatshisi ilangatye. Ukuba igrafiti enokwandiswa yongezwa ngokuthe ngqo, isakhiwo somaleko wekhabhoni esenziwe emva kokutsha ngokuqinisekileyo asixinene. Ke ngoko, kwimveliso yemizi-mveliso, kufuneka kongezwe igrafiti enokwandiswa, enefuthe elihle lokungatshisi ilangatye kwinkqubo yokuguqulwa ibe yigrafiti enokwandiswa xa itshiswa.
