oneone auro mo le fa'ameamea o le oneone
Foundry Ceramic Sand, faʻaigoa faʻaigoaina o le "Sintered Ceramic Sand for Foundry", e taʻua foi o ceramsite, cerabeads, ceramcast, o nisi atunuu e taʻua foi Golden Sand, o se foliga lelei o le fatu spherical spherical lea e faia mai le calcined bauxite.O lona anotusi autu o le alumini oxide ma le Silicon oxide.O le oneone sima, e sili atu lona lelei nai lo le oneone silica e maua ai se faʻatinoga sili atu i le fau.E maualuga refractoriness, itiiti faalauteleina vevela, coefficient angular lelei, lelei flowability, maualuga tetee e ofuina, nutimomoia ma vevela te'i, maualuga reclamation fua faatatau.

Fa'amanuiaga
Kaist sima fau oneone e tusa ma le afa mama e pei o le zircon ma le chromite, e tusa ma le tolu le mama e pei o le oneone sima fused.Fa'atusatusa i nei oneone fa'alenatura ma isi fa'asalalauga fa'apipi'i (o mea e mafai ona fa'aluaina le aofa'i o limu ile iunite mamafa).Kaist ceramic foundry sand e mafai ona tuʻuina atu faʻamaʻi ma pusa autu ma le tele o faʻamanuiaga e aofia ai pusa faʻapipiʻi oneone sili atu le malosi, faʻatasi ai ma le maualuga o le vevela, faʻalauteleina le vevela, faʻaleleia vaega mulimuli ma le faʻamaeʻaina o luga.E mafai fo'i ona fa'afaigofie tele, fa'asaoina o tagata faigaluega ma fa'aliliuina tau o le eletise.Ae ui i lea, e fautuaina e le gaosi oloa le gauai atu i le aofaʻi o faʻaopoopoga faʻapipiʻi.
Fa'atatauga
I le avea ai o se mea le faaituau, KAIST oneone ceramic e faatatau i resins acid ma alkali.
E mafai ona faʻaaogaina lautele mo le uʻamea uʻamea, lafo uʻamea ma nonferrous uʻamea lafo, e pei o le leiloa foam lafo, oneone ufiufi, resin sand, pusa autu malulu, lafo saʻo, ma 3D lomitusi.
