Isanti yeCeramic eSpherical ye-Foundry

Inkcazelo emfutshane:

ISanti yeCeramic ye-Foundry, ebizwa ngokobuchwephesha njenge "Sintered Ceramic Sand for Foundry", ekwabizwa ngokuba yi-ceramsite, i-ceramcast, 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

● Intlabathi eluhlaza. IKHUSELEKILE kwindawo engqongileyo xa kuthelekiswa ne-silica (silicosis) kunye nesanti ye-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.
● Izinga eliphezulu lokubuyisela. Zombini i-Thermal kunye ne-mechanical reclamation. Inika ubomi obude bomsebenzi kunye nokunciphisa ukusetyenziswa kwesanti.
● Ukugoba okuphezulu. Isanti yeCeramic esintered imilo engqukuva xa ithelekiswa neenkozo ezimilise okwe-angular ivumela ukwahlulwa lula kwiindawo ezisasisiweyo kunye nokuphucula ukubola okukhokelela kwi-scrap esezantsi kunye nokusebenza kakuhle kokuphosa.
● Ubumanzi obugqwesileyo kunye nokusebenza kakuhle kokuzalisa ngenxa yokuba singqukuva.
● Ukwandiswa kwe-Thermal ephantsi kunye ne-Thermal Conductivity. Imilinganiselo yokuphosa ichaneke ngakumbi kwaye i-conductivity ephantsi ibonelela ngokusebenza okungcono kokungunda.
● Ubuninzi bobuninzi obusezantsi. Njengoko isanti eyenziweyo yeceramic yokwenziwa imalunga nesiqingatha sokukhanya njengesanti yeseramikhi edityanisiweyo (isanti yebhola emnyama), i-zircon kunye nekhromite, inokujika malunga nenani eliphindwe kabini lemold yeyunithi nganye. Inokusingathwa ngokulula kakhulu, ukonga abasebenzi kunye neendleko zamandla okudluliselwa. Nangona kunjalo, ingqwalasela kufuneka inikwe kwisixa sokudibanisa isibophelelo.
● Ifuna i-40-50% ngaphantsi kwe-resin.
● Iicasta ziqatywe nge-coat encinci okanye zingabikho.
● Inokusetyenziswa njengesanti enye.
● Unikezelo oluzinzileyo. Umthamo wonyaka we-200,000 MT ukugcina unikezelo olukhawulezayo noluzinzileyo.

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.
