Gaineamh órga le haghaidh teilgin múnlaithe gaineamh

Cur síos gairid:

Teilgcheárta Ceirmeacha Gaineamh, ainmnithe go teicniúil mar "Sintered Ceirmeach Gaineamh do Teilgcheárta", freisin ainmnithe mar ceramsite, ceramcast, mar an gcéanna le cerabeads, tá roinnt tíortha ainmnithe freisin Golden Sand, tá cruth gráin saorga sféarúil maith atá déanta as báicsít cailcínithe. Is é a phríomh-ábhar ocsaíd alúmanaim agus ocsaíd Sileacain. Tá airíonna i bhfad níos fearr ag gaineamh ceirmeach ná mar atá ag gaineamh shilice chun feidhmíocht níos fearr a bhaint amach sa teilgcheárta. Tá teasfhulangacht ard aige, is beag leathnú teirmeach, comhéifeacht uilleach maith, cumas sreafa den scoth, Friotaíocht ard le caitheamh, crush agus turraing teirmeach, ráta míntírithe ard.

Sonraí Táirge

Clibeanna Táirge

Foundry Ceramic Sand, technically named as “Sintered Ceramic Sand for Foundry”, also named as ceramsite, cerabeads, ceramcast, some countries is also named Golden Sand, is good artificial spherical grain shape which is made from calcined bauxite . Its main content is aluminum oxide and Silicon oxide. Ceramic sand, has much better properties than that of silica sand to gain a better performance in foundry. It has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, High resistance to wear, crush and thermal shock, high reclamation rate.

Buntáiste

Kaist ceramic foundry sand is about half as light as zircon and chromite, is about third as light as fused ceramic sand. Compared to these natural sand and other foundry media (the material is able to turn out about twice the number of molds per unit weight). Kaist ceramic foundry sand can deliver mold and core packages with a range of benefits that include higher-strength sand casting packages, with high heat resistance, low thermal expansion, improved final part resolution and a smoother surface finish. It can also be handled very easily, saving labor and transfer power costs. However, the manufacturer recommends paying attention to the amount of binder addition.

Iarratas

Mar ábhar neodrach, tá gaineamh ceirmeach KAIST infheidhme maidir le roisíní aigéad agus alcaile.

Is féidir é a úsáid go forleathan le haghaidh iarann teilgthe, cruach teilgthe agus miotail neamhfheiriúla réitigh, mar shampla réitigh cúr caillte, gaineamh brataithe, gaineamh roisín, bosca croí fuar, réitigh cruinneas, agus priontáil 3D.
