Menene kyawawan kaddarorin graphite da aka faɗaɗa

1. Aikin injiniya:
1.1Babban matsawa da juriya: don samfuran graphite da aka faɗaɗa, har yanzu akwai ƙananan ƙananan wuraren buɗewa da yawa waɗanda za a iya ƙarfafa su ƙarƙashin aikin ƙarfin waje. A lokaci guda kuma, suna da juriya saboda tashin hankali na iska a cikin ƙananan wuraren budewa.
1.2sassauci: taurin ya yi ƙasa sosai. Ana iya yanke shi da kayan aiki na yau da kullun, kuma ana iya raunata shi da lankwasa ba da gangan ba;
2. Ayyukan jiki da sinadarai:
2.1 Tsarkakewa: ƙayyadadden abun ciki na carbon shine kusan 98%, ko ma fiye da 99%, wanda ya isa ya dace da buƙatunhigh-tsarkihatimi a cikin makamashi da sauran masana'antu;
2. Yawa: dayawa yawana flake graphite ne 1.08g/cm3, da girma yawa na fadada graphite ne 0.002 ~ 0.005g/cm3, da samfurin yawa ne 0.8 ~ 1.8g/cm3. Sabili da haka, kayan graphite da aka faɗaɗa shine haske da filastik;
3. Juriya yanayin zafi: a ka'idar, da fadada graphite iya jure - 200 ℃ zuwa 3000 ℃. A matsayin hatimin shiryawa, ana iya amfani da shi lafiya a -200 ℃ ~ 800 ℃. Yana da ayyuka masu kyau na rashin haɓakawa, babu tsufa a ƙananan zafin jiki, babu laushi, babu lalacewa kuma babu lalacewa a babban zafin jiki;
4. Juriya na lalata: yana da kasala na sinadarai. Baya ga wasu takamaiman yanayin zafi mai ƙarfi na oxidants kamar aqua regia, nitric acid, sulfuric acid da halogen, ana iya amfani dashi ga yawancin kafofin watsa labarai kamar acid, alkali, maganin gishiri, ruwan teku, tururi da sauran ƙarfi;
5. Kyakkyawan thermal conductivityda ƙananan haɓakar haɓakar thermal. Siffofin sa suna kusa da tsari iri ɗaya na girman bayanan sassa biyu na kayan aikin hatimi gabaɗaya. Hakanan za'a iya rufe shi da kyau a ƙarƙashin yanayin aiki na babban zafin jiki, canjin yanayin cryogenic da kaifi;
6. Radiation resistante: ƙarƙashin hasken neutron γ Ray α Ray β X-ray irradiation na dogon lokaci ba tare da canji na zahiri ba;
7. Impermeability: mai kyau impermeability ga gas da ruwa. Saboda babban makamashi na sararin samaniya na graphite mai girma, yana da sauƙi don samar da fim din gas na bakin ciki ko fim na ruwa don hana matsakaicin shiga;
8. Lubrication kai: Faɗaɗɗen graphite har yanzu yana kula da tsarin shimfidar tsarin jirgin sama hexagonal. Ƙarƙashin aikin ƙarfin waje, layin jirgin yana da sauƙi don zamewa in mun gwada da kuma lubrication kai yana faruwa, wanda zai iya hana lalacewa na shaft ko sandar bawul.
