Ceramic casting sand for sand 3d printing Featured Image

ʻO Sand Ceramic Spherical no ka hana ʻana

ʻO ka wehewehe pōkole:

ʻO ke Sand Ceramic Foundry, i kapa ʻia ʻo "Sintered Ceramic Sand for Foundry", i kapa ʻia ʻo ceramsite, ceramcast, he ʻano hua ʻai spherical maikaʻi i hana ʻia mai ka bauxite calcined. ʻO kāna mea nui he alumini oxide a me Silicon oxide. ʻOi aku ka maikaʻi o nā waiwai ma mua o ke one silica no ka loaʻa ʻana o ka hana ʻoi aku ka maikaʻi ma ka foundry. He kiʻekiʻe refractoriness, liʻiliʻi thermal hoʻonui, maikaʻi angular coefficient, maikaʻi flowability, Kiʻekiʻe kū'ē i ka lole, ka'ūʻana a me ka wela haʻalulu, kiʻekiʻe reclamation rate.

Pōmaikaʻi

● Ke one ʻōmaʻomaʻo. SAFE i ke kaiapuni i hoʻohālikelike ʻia me ka silica (silicosis) a me ke one 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.
● Kiʻekiʻe o ka hoʻoponopono hou ʻana. ʻO ka Thermal a me ka mechanical reclamation. Hāʻawi i ke ola hana lōʻihi a me ka hoʻemi ʻana i ka hoʻohana ʻana i ke one.
● Kiʻekiʻe collapsibility. ʻO ke ʻano spherical one Ceramic Sintered i hoʻohālikelike ʻia me nā hua ʻano angular e hiki ai ke maʻalahi ka hoʻokaʻawale ʻana mai nā ʻāpana hoʻolei a hoʻomaikaʻi i ka collapsibility e hopena i ka ʻōpala haʻahaʻa a me ka maikaʻi o ka hoʻolei ʻana.
● ʻOi aku ka maikaʻi o ka wai a me ka hoʻopiha piha ʻana ma muli o ka spherical.
● Lower Thermal hoonui a me Thermal Conductivity. ʻOi aku ka pololei o ka hoʻoheheʻe ʻana a ʻoi aku ka maikaʻi o ka conductivity haʻahaʻa.
● Haʻahaʻa haʻahaʻa nui. E like me ka hapalua o ka māmā o ke one seramika i hoʻohui ʻia (ke one pōʻeleʻele), ka zircon a me ka chromite, hiki ke hoʻololi ʻia ma kahi o ʻelua o ka nui o nā mold i kēlā me kēia paona. Hiki ke mālama maʻalahi, mālama i ka hana a me ka hoʻololi ʻana i nā kumukūʻai mana. Eia naʻe, pono e noʻonoʻo i ka nui o ka hoʻohui hoʻohui.
● Pono 40-50% emi resin.
● Hoʻopili ʻia nā mea hoʻolei me ka liʻiliʻi a i ʻole ka uhi ʻole.
● Hiki ke hoʻohana ʻia e like me ke one hoʻokahi.
● lako paʻa. ʻO ka mana makahiki 200,000 MT e mālama i ka lako wikiwiki a paʻa.

Palapala noi

Ma ke ʻano he mea kūʻokoʻa, pili ke one ceramic KAIST i nā resins acid a me ka alkali.

Hiki ke hoʻohana nui ʻia no ka hoʻolei ʻana i ka hao, ke kila a me ka hoʻolei ʻana i nā metala nonferrous, e like me ka hoʻolei ʻana i ka pahu, ke one i uhi ʻia, ke one resin, ka pahu pahu anuanu, ka hoʻolei pololei ʻana, a me ka paʻi 3D.

Nā ʻāpana o ka puʻupuʻu nui ʻāpana

Hiki ke hoʻopilikino ʻia ka puʻupuʻu ʻāpana nui e like me kāu koi.
