Tare da ci gaba da sakin ƙarfin samarwa, sabbin matsa lamba da ƙalubale ana kawo su a hankali ga kamfanonin graphite masu tsattsauran ra'ayi.
1. Menene graphite isostatic?
Isostatic graphite yana nufin kayan graphite da aka samar ta latsa isostatic. Saboda graphite da aka matse a cikin keɓancewa ana matsa shi daidai kuma a hankali ta hanyar matsa lamba na ruwa yayin aiwatar da gyare-gyare, kayan graphite da aka samar yana da kyawawan kaddarorin. Tun lokacin da aka haife shi a cikin 1960s, graphite isostatic ya zama jagora a tsakanin sabbin kayan graphite saboda kaddarorin sa na musamman da aikace-aikace masu yawa.
2. Isostatic graphite samar tsari
Ana nuna kwararar tsarin samarwa na graphite da aka danna isostatically a cikin adadi. Isostatic graphite yana buƙatar albarkatun isotropic na tsari. Ana buƙatar ɗanyen kayan da aka niƙa su zama ƙoshin foda. Ana buƙatar yin amfani da fasahar gyare-gyaren matsi na isostatic. Zagayen gasassun yana da tsayi sosai. Domin cimma maƙasudin yawan niyya, ana buƙatar jujjuyawar impregnation da hawan gasa. , lokacin graphitization kuma ya fi tsayi fiye da na graphite na yau da kullun.
3. Aikace-aikace na graphite isostatic
Isostatic graphite yana da fa'idodin aikace-aikace, galibi a cikin semiconductor da filayen hotovoltaic.
A fagen photovoltaics, isostatically man graphite ne yafi amfani a graphite aka gyara a cikin graphite thermal filin a guda crystal silicon girma tanda da kuma graphite thermal filin a polycrystalline silicon ingot tanda. Musamman, clamps don samar da kayan siliki na polycrystalline, masu rarraba iskar gas don tanderun hydrogenation, abubuwan dumama, silinda masu rufewa da polycrystalline ingot heaters, tubalan shugabanci, kazalika da bututun jagora don ci gaban kristal ɗaya da sauran ƙananan girma. sassa;
A fagen semiconductors, dumama da insulation cylinders don sapphire guda crystal girma na iya amfani da ko dai isostatic graphite ko molded graphite. Bugu da kari, sauran abubuwan da aka gyara kamar crucibles, heaters, electrodes, zafi-insulating garkuwa faranti, da iri Lu'ulu'u Kimanin iri 30 na mariƙin, da tushe don jujjuya crucibles, daban-daban madauwari faranti, da zafi tunani faranti an yi su ne da graphite wanda aka matse shi.
