Ina ia mafai ona fetaui lelei ma manaoga o le tagata o tausia, o a matou gaioiga uma e matua faʻatinoina e tusa ai ma la matou mautauave "Maualuga Maualuga, Tau Faʻatauvaʻa, Auauna Vave" moSaina Graphite Mold ma Graphite, Ina ia faʻamalieina tagata uma ia i matou ma ausia le manumalo-manumalo manuia, o le a matou faʻaauau pea ona taumafai i le mea sili matou te mafaia e tautua ma faʻamalieina oe! O loʻo tulimatai atu ma le faʻamaoni e galulue faʻatasi ma le tele o tagata faʻatau mai fafo e faʻavae i luga o faʻamanuiaga faʻatasi ma pisinisi sili i le lumanaʻi. Fa'afetai.
Siliconized graphite o se mea tu'ufa'atasi lea o lo'o fa'apipi'i ai le silicon carbide i luga o se mea fa'apipi'i kalafi. O loʻo i ai uiga o le maualuga o le maʻaʻa, maualuga le malosi faʻainisinia ma le faʻaogaina o le faʻaogaina o le carbide silicon, faʻapea foʻi ma le faʻaogaina o le tagata lava ia ma le teteʻe o le vevela o le graphite. O se mea faʻafefeteina lelei ma mea faʻamaufaʻailoga masini, talafeagai mo le faʻamaufaʻailogaina o pamu vai eseese, pamu suauʻu, pamu vailaʻau, ma paʻu o pamu autu eseese maualuga ma maualuga. E le gata i lea, o le siliconized graphite o loʻo i ai le faʻamaʻiina lelei o le faʻamaʻiina, teteʻe o le vevela, le maualalo o le porosity, ma le faʻaogaina o le eletise, ma e mafai ona faʻaaogaina e fai ma mea e pei o uʻamea faʻafefeteina uʻamea ma paipa faʻapipiʻi.
O le tuufaatasiga o le siliconized graphite e toniga, o le pito i luga e ogatasi ma totonu, ma o le fua faatatau o le silicon carbide ma le graphite e fetuutuunai. O le maualuga o le mea o loʻo i totonu o le carbide silicon, o le sili atu lea o le mamafa o le meafaitino, o le maualuga atu lea o le malosi faʻamalosi, ma faʻateleina le resistivity.
