Taonga oumu He karāhe silicon He kurupae me he roera
He kaha ake ngā kurupae whakawhiti ZPC-RBSiC (SiSiC) ā, kāore he rerekētanga ahakoa i roto i te pāmahana tino tiketike. Ā, he roa hoki te ora o ngā kurupae. Ko ngā kurupae te mea tino pai mō ngā taonga oumu mō ngā kakahu horoi me ngā mahi porcelain hiko. He tino pai te kawe wera o te Shang mei RBSiC (SiSiC), nō reira ka taea te penapena pūngao me te whakaiti i te taumaha o te motuka oumu.
E whakamahia ana ngā kurupae me ngā roera silicon carbide hei anga uta i roto i ngā oumu hanga porcelain, ā, ka taea te whakakapi i te pereti silicon me te pou mullite kua herea ki te waikura noa nā te mea he pai ngā painga pēnei i te penapena wāhi, wahie, pūngao me te poto o te wā tahu, ā, he maha ngā wā e ora ai ēnei rauemi i ētahi atu, he tino pai rawa atu tēnei mō ngā taonga oumu. Ko te kurupae silicon carbide te nuinga o te wā e whakamahia ana hei mema kawe uta i roto i te oumu kauhanga, te oumu whakawhiti me te oumu awa rua. Ka taea hoki te whakamahi hei taonga oumu i roto i te umanga uku me te ahumahi ātete ahi.
He kurupae he kaha ki te pupuri i te pāmahana teitei, he whakamahinga nui, he whakamahinga roa, kāore e piko te āhua, he tino pai mō ngā oumu kauhanga, oumu whakawhiti, oumu roera paparua me ētahi atu hanganga anga e pupuri ana i te kawenga oumu ahumahi. Ka whakamahia ngā karapu ki ngā uku e whakamahia ana i ia rā, ki te porcelain parakore, ki te uku hanga whare, ki ngā rauemi aukume me te rohe tahu pāmahana teitei o te oumu roera.

Ko Shandong Zhongpeng Special Ceramics Co., Ltd tētahi o ngā otinga rauemi hou uku silicon carbide nui rawa atu i Haina. Uku hangarau SiC: Ko te pakeke o Moh he 9 (ko te pakeke o Moh hou he 13), he ātete pai ki te horo me te waikura, he ātete pai ki te pakū me te ārai-waikura. Ko te roa o te ora ratonga o te hua SiC he 4 ki te 5 ngā wā roa atu i te rauemi alumina 92%. Ko te MOR o RBSiC he 5 ki te 7 ngā wā i tō SNBSC, ka taea te whakamahi mō ngā āhua uaua ake. He tere te tukanga whakatau utu, ko te tuku e rite ana ki te mea i oatitia, ā, ko te kounga kāore he rite. Ka tohe tonu mātou ki te wero i ā mātou whāinga me te tuku i ō mātou ngākau ki te hapori.
