Sand Ceramic Spherical mo Faumea

Fa'amatalaga Puupuu:

Foundry Ceramic Sand, faʻaigoa faʻapitoa o le "Sintered Ceramic Sand for Foundry", e taʻua foʻi o le ceramsite, ceramcast, o se faʻataʻitaʻiga lelei o le saito 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 ona lelei meatotino 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, tu'imomomo ma vevela te'i, maualuga reclamation fua faatatau.

Fa'amanuiaga

● oneone lanumeamata. SAFE i le si'osi'omaga fa'atusatusa i le silica (silicosis) ma le oneone zircon
● High refractoriness (＞1800°C)，can be used for casting various materials. There is also no need to use different sand type according to material.
● maualuga le fua faatatau o le tanu. Toe fa'amama ma fa'ainisinia. E ofoina atu le umi o le olaga faigaluega ma le faʻaitiitia o le faʻaaogaina o oneone.
● Maualuluga le pa'u. Sintered Ceramic oneone foliga lapotopoto fa'atusatusa i fatu fa'ata'ifa'i fa'afaigofie ona tu'u'ese'ese mai vaega lafo ma fa'aleleia atili le pa'u e mafua ai ona fa'aitiitia le fa'amama ma le lelei o le lafo.
● Lelei lelei le sua ma le fa'atumu lelei ona o le lapotopoto.
● Faʻalauteleina le vevela ma lalo ifo o le vevela. Ole fua ole lafo e sili atu ona sa'o ma maualalo le conductivity e maua ai le fa'atinoga sili atu.
● Faʻaititia le mamafa tele. A'o le oneone sima fa'afuafua e tusa ma le afa le malamalama e pei o le oneone sima fused (lanu uliuli polo), zircon ma chromite, e mafai ona liliu mai e tusa ma le faaluaina le numera o limu i le iunite mamafa. E mafai fo'i ona fa'afaigofie tele, fa'asaoina o tagata faigaluega ma fa'aliliuina tau eletise. Ae ui i lea, e tatau ona gauai atu i le aofaʻi o faʻaopoopoga faʻapipiʻi.
● Manaʻomia 40-50% itiiti resin.
● E faʻapipiʻi mea e faʻapipiʻi i sina mea itiiti pe leai foi.
● E mafai ona faʻaaogaina e pei o se oneone e tasi.
● Sapalai mautu. Malosiaga faaletausaga 200,000 MT e tausia ai le sapalai vave ma mautu.

Fa'aaogāga

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 metala lafo, e pei o le leiloa foam lafo, oneone ufiufi, resin sand, pusa autu malulu, lafo saʻo, ma 3D lomitusi.

Vaega o Fa'asoa Lapopo'a

E mafai ona fa'avasegaina le fa'asoaina o le lapopoa e tusa ai ma lou mana'oga.
