Ceramic sand properties

O le oneone fau sima, e ta'ua foi o le ceramsite, cerabeads, o ni faavae lelei o le oneone polo.Faatusatusa i le oneone Silica, e maualuga refractoriness, itiiti faalauteleina vevela, coefficient angular lelei, lelei flowability, tetee maualuga i le ofuina, maualuga reclamation fua faatatau, e mafai ona faaitiitia le resin faaopoopo ma le aofaiga o le ufiufi, faateleina lou maua castings.

Kaist Ceramic u'u oneone e matua'i taugofie i le fa'amea oneone.

Kaist Ceramic fa'ailoga oneone

● Fa'amautu le fa'asoaina o saito ma le fa'aogaina o le ea

● Maua maualuga (＞1800°C)

● Teteʻe maualuga i le ofuina, nutimomoia ma le vevela vevela

● maualuga le fua faatatau o le tanu

● Maualuluga le pa'u.

● Laititi le faʻalauteleina o le vevela

● Lelei lelei le sua ma le fa'atumu lelei ona o le lapotopoto
