He aha nā waiwai maikaʻi o ka graphite hoʻonui

1, hana mīkini:
1.1Kiʻekiʻe compressibility a me resilience: no nā huahana graphite i hoʻonui ʻia, aia nā wahi ākea liʻiliʻi i pani ʻia e hiki ke hoʻopaʻa ʻia ma lalo o ka hana o ka ikaika o waho. I ka manawa like, loaʻa iā lākou ke kūpaʻa ma muli o ka haʻalulu o ka ea ma nā wahi ākea liʻiliʻi.
1.2ʻoluʻolu: haahaa loa ka paakiki. Hiki ke ʻoki ʻia me nā mea hana maʻamau, a hiki ke ʻeha a hoʻopōloli ʻia;
2. Nā hana kino a me ke kemika:
2.1 Maʻemaʻe: ʻo ka waihona kalapona paʻa e pili ana i 98%, a i ʻole ʻoi aku ma mua o 99%, ua lawa ia e hoʻokō i nā koi omaʻemaʻe kiʻekiʻenā sila i ka ikehu a me nā ʻoihana ʻē aʻe;
2. Density: kamānoanoa nuiʻO ka graphite flake he 1.08g / cm3, ʻo ka nui o ka nui o ka graphite i hoʻonui ʻia he 0.002 ~ 0.005g/cm3, a ʻo ka nui o ka huahana he 0.8 ~ 1.8g/cm3. No laila, he māmā a me ka plastic ka mea graphite i hoʻonui ʻia;
3. Kūleʻa wela: theoretically, hiki i ka graphite hoʻonui ke kū - 200 ℃ a 3000 ℃. Ma ke ʻano he sila packing, hiki ke hoʻohana pono ʻia ma - 200 ℃ ~ 800 ℃. Loaʻa iā ia nā hana maikaʻi ʻole o ka embrittlement, ʻaʻohe ʻelemakule ma ka wela haʻahaʻa, ʻaʻohe palupalu, ʻaʻohe deformation a ʻaʻohe decomposition i ke kiʻekiʻe wela;
4. ʻO ke kūpaʻa ʻino: loaʻa iā ia ka palaualelo kemika. Ma waho aʻe o kekahi mau mahana kiko'ī o nā meaʻokiʻoki ikaika e like me ka aqua regia, ka nitric acid, ka sulfuric acid a me ka halogen, hiki ke hoʻohanaʻia i ka nui o nā media e like me ka waikawa, ka alkali, ka paʻakai paʻakai, ka wai kai, ka mahu a me ka mea hoʻoheheʻe organik;
5. ʻOi aku ka maikaʻi o ka thermal conductivitya me ka helu hoʻonui wela liʻiliʻi. Kokoke kona mau palena i ka hoʻonohonoho like o ka nui o ka ʻikepili ʻāpana ʻelua o nā lako hoʻopaʻa maʻamau. Hiki ke hoʻopaʻa maikaʻi ʻia ma lalo o nā kūlana hana o ka wela kiʻekiʻe, cryogenic a me ka hoʻololi ʻana o ka mahana;
6. Ka pale ʻana i ka radiationce: e pili ana i nā kukuna neutron γ Ray α Ray β X-ray irradiation no ka manawa lōʻihi me ka ʻike ʻole o ka loli;
7. Impermeability: maikaʻi impermeability i ke kinoea a me ka wai. Ma muli o ka nui o ka ikehu o ka graphite i hoʻonui ʻia, ua maʻalahi ka hana ʻana i kahi kiʻiʻoniʻoni kinoea lahilahi a i ʻole ka wai kiʻiʻoniʻoni e pale ai i ke komo ʻana;
8. Lubrication pono'ī: ke hoʻomau nei ka graphite i hoʻonui ʻia i ke ʻano hexagonal plane layered. Ma lalo o ka hana o ka ikaika o waho, maʻalahi ka paheʻe ʻana o nā papa mokulele a loaʻa ka lubrication ponoʻī, hiki ke pale pono i ka ʻaʻahu o ka shaft a i ʻole ke koʻokoʻo valve.
