Ceramic casting sand for sand 3d printing Featured Image

Isanti yegolide yokubunjwa kwesanti

Inkcazelo emfutshane:

ISanti yeCeramic ye-Foundry, ebizwa ngokobuchwephesha njenge "Sintered Ceramic Sand for Foundry", ekwabizwa ngokuba yi-ceramsite, i-ceramcast, ifana ne-cerabeads, amanye amazwe ikwabizwa ngokuba yiSanti yeGolide, ilungile imilo engqukuva engqukuva eyenziwe nge-bauxite ene-calcined. Umxholo wayo oyintloko yi-aluminium oxide kunye ne-Silicon oxide. Isanti yeCeramic, ineepropathi ezingcono kakhulu kunesanti ye-silica ukufumana umsebenzi ongcono kwi-Foundry. Inokuphikiswa okuphezulu, ukwandiswa kwe-thermal encinci, i-coefficient ye-angular elungileyo, ukuhamba okugqwesileyo, ukuxhathisa okuphezulu ukunxiba, ukutyumza kunye nokothuka kwe-thermal, izinga eliphezulu lokubuyisela.

Inzuzo

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.

Isicelo

Njengezinto ezingathathi hlangothi, isanti ye-ceramic ye-KAIST iyasebenza kwi-asidi kunye ne-alkali resins.

Ingasetyenziselwa ngokubanzi intsimbi etyhidiweyo, intsimbi etyhidiweyo kunye neentsimbi ezingezizo, ezifana nokuphosa amagwebu alahlekileyo, isanti egqunyiweyo, isanti yeresin, ibhokisi engundoqo ebandayo, ukuphosa ngokuchanekileyo, kunye noshicilelo lwe-3D.
