Ramel tad-deheb għall-ikkastjar tal-iffurmar tar-ramel

Deskrizzjoni qasira:

Ramel taċ-ċeramika tal-Funderija, imsejjaħ teknikament bħala "Ramel taċ-ċeramika sinterizzat għall-Funderija", imsejjaħ ukoll bħala ceramsite, ceramcast, l-istess ma 'cerabeads, xi pajjiżi jismu wkoll Golden Sand, huwa forma tajba ta' qamħ sferiku artifiċjali li huwa magħmul minn boksajt kalċinat. Il-kontenut ewlieni tiegħu huwa l-ossidu tal-aluminju u l-ossidu tas-silikon. Ramel taċ-ċeramika, għandu proprjetajiet ferm aħjar minn dak tar-ramel tas-silika biex jikseb prestazzjoni aħjar fil-funderija. Għandu refrattanza għolja, ftit espansjoni termali, koeffiċjent angolari tajjeb, fluss eċċellenti, Reżistenza għolja għal xedd, tgħaffiġ u xokk termali, rata għolja ta 'reklamazzjoni.

Tags tal-Prodott

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.

Vantaġġ

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.

Applikazzjoni

Bħala materjal newtrali, ir-ramel taċ-ċeramika KAIST huwa applikabbli għar-reżini aċidużi u alkali.

Jista 'jintuża ħafna għall-ikkastjar tal-ħadid fondut, azzar fondut u metalli mhux tal-ħadid, bħal ikkastjar tal-fowm mitluf, ramel miksi, ramel tar-reżina, kaxxa tal-qalba kiesħa, ikkastjar ta' preċiżjoni u stampar 3D.
