I-graphite ekhutshiweyo yinto efana nempethu ekhululekileyo nenemingxuma eyenziwe kwiiflakes zegraphite ngokusebenzisa iinkqubo zokudibanisa, ukuhlamba ngamanzi, ukomisa kunye nokwandiswa kobushushu obuphezulu. I-graphite ekhutshiweyo inokwanda ngoko nangoko amaxesha ali-150 ~ 300 ngomthamo xa ibekwe kubushushu obuphezulu, itshintsha ukusuka kwi-flake ukuya kwi-worm, ukuze isakhiwo sibe sikhulu, sinemingxuma kwaye sigobile, indawo yomphezulu yande, amandla omphezulu aphuculwe, kwaye amandla okufunxa i-graphite ye-flake aphuculwe. zidityaniswe, nto leyo enyusa ukuthamba kwayo, ukuqina kwayo kunye nokuqina kwayo. Umhleli olandelayo uza kukuchazela iindlela eziphambili zophuhliso lwe-graphite ekhutshiweyo:
1. I-Graphite enwetshiweyo eneziqwenga: I-Graphite encinci enwetshiweyo eneziqwenga ibhekisa ikakhulu kwi-graphite enokwandiswa eneziqwenga ezingama-300, kwaye umthamo wayo wokwandiswa yi-100ml/g. Le mveliso isetyenziselwa ikakhulu izinto zokugquma ezithintela ilangatye, kwaye imfuno yayo inkulu kakhulu.
2. Igrafiti eyandisiweyo enobushushu obuphezulu bokuqala bokukhula: ubushushu bokuqala bokukhula buyi-290-300 ° C, kwaye umthamo wokukhula yi-≥ 230 ml/g. Olu hlobo lwegrafiti eyandisiweyo lusetyenziswa kakhulu kwi-retardant yomlilo yeplastiki yobunjineli kunye nerabha.
3. Ubushushu obuphantsi bokuqala bokwandiswa kunye nobushushu obuphantsi begrafiti ekhuliswe: ubushushu apho olu hlobo lwegrafiti ekhuliswe luqala khona ukwanda buyi-80-150°C, kwaye umthamo wokwandiswa ufikelela kwi-250ml/g kwi-600°C.
Abavelisi begrafiti eyandisiweyo banokucubungula igrafiti eyandisiweyo ibe yigrafiti eguquguqukayo ukuze isetyenziswe njengezinto zokuvala. Xa kuthelekiswa nezinto zokuvala zemveli, igrafiti eguquguqukayo inoluhlu olubanzi lwamaqondo obushushu asebenzisekayo, ukusuka kwi--200°C ukuya kwi-450°C emoyeni, kwaye inomlinganiselo omncinci wokwandisa ubushushu. Isetyenziswe kakhulu kwi-petrochemical, koomatshini, kwi-metallurgy, kumandla e-athomu nakwamanye amashishini.
