Qhov nro ntawm flake graphite yog me me, tsis muaj qhov tsis xws luag hauv cheeb tsam loj, thiab muaj li ntawm 0.45% volatile organic tebchaw nyob rau saum npoo ntawm flake graphite, uas tag nrho deteriorate lub wettability ntawm flake graphite. Lub zog hydrophobicity nyob rau saum npoo ntawm flake graphite ua rau lub fluidity ntawm castable, thiab flake graphite nyhav aggregate es disperse tusyees nyob rau hauv lub refractory, yog li nws yog ib qho nyuaj rau npaj ib tug uniform thiab ntom amorphous refractory. Cov nram qab no me me ntawm Furuite graphite tsom xam ntawm lub wettability thiab daim ntawv thov txwv ntawm flake graphite:
Flake graphite
Cov microstructure thiab cov khoom ntawm flake graphite tom qab kub sintering feem ntau yog txiav txim siab los ntawm cov wettability ntawm kub silicate kua rau flake graphite. Thaum ntub dej, silicate kua theem nyob rau hauv qhov kev txiav txim ntawm capillary quab yuam, mus rau hauv qhov sib txawv particle, los ntawm adhesion ntawm lawv los khi cov flake graphite hais, nyob rau hauv tsim ntawm ib txheej ntawm zaj duab xis nyob ib ncig ntawm lub flake graphite, tom qab txias los tsim ib tug continuum, thiab tsim ntawm siab adhesion interface nrog flake graphite. Yog hais tias ob qho tib si tsis wetted, lub flake graphite particles tsim aggregates, thiab lub silicate kua theem yog nyob rau hauv lub particle kis thiab tsim ib tug cais lub cev, uas yog ib qho nyuaj rau tsim ib tug ntom complex nyob rau hauv high kub.
Yog li ntawd, Furuite graphite xaus lus tias lub wettability ntawm flake graphite yuav tsum tau txhim kho kom thiaj li npaj tau zoo carbon refractories.
