Kaihanga/wheketere o ngā Para me ngā Sagger SiC – Sagger SiC mō te Sintering Paura
SiC Sagger mō te Sintering Paura
He peihana hohonu te para RBSIC/SISIC, he ipu uku kei roto. Nā tōna ātete wera pai ake i ngā mea karāhe, he pai te whakamahi ina werahia ngā mea totoka ki te ahi.
He mea hanga te Sagger ki te paru ātete-wera o ngā momo āhua o te moata, ka tunua ki te pāmahana teitei. Ko tētahi o ngā taonga oumu nui mō te tahu porcelain. Me maka ngā momo porcelain katoa ki roto i ngā sagger i te tuatahi, kātahi ki roto i te oumu hei tunu.

TE TUKANGA OTA:
TE TUKANGA HANGA:
Ka taea te whakamahi i ngā oko uku me ngā oko whakarewa silicon carbide mō ngā momo mahi sintering paura, te whakarewa whakarewa, me ētahi atu i roto i ngā mara o te metallurgy, te ahumahi matū, te karāhe me ērā atu mea pera. E whakapau kaha ana a Shandong Zhongpeng ki te rangahau me te whakawhanake, te whakaputa me te hoko i ngā hua silicon carbide mahi-teitei. Ko ngā hua matua ko ngā kurupae uku silicon carbide tauhohenga, ngā pae roera, ngā pūwero ahi, ngā paipa hau makariri, ngā whare pupuri, te enamel, te enamel, ngā ngongo tiaki thermocouple, ngā ngongo whakawhiti wera, te ngongo ngongo roto, te ngongo ngongo o waho, te pūwero desulfurization, te hoe cantilever, te ngongo oumu hau, te pūwero pupuhi onepu, te pūwero, te hiri me ngā momo uku silicon carbide ātete pāmahana teitei, ātete kakahu me te waikura, me ētahi atu. Ko ngā hua uku silicon carbide tauhohenga me te kaha teitei, te pakeke teitei, te ātete kakahu, te ātete pāmahana teitei, te ātete waikura, te ātete waikura, te ātete ru wera me te kawe wera, te ātete ki te tinei me te ātete tere me te ngoki pāmahana teitei, e whakamahia whānuitia ana i roto i te ope taua, te rererangi, te mana karihi, te karaihe wai me te whakarewa, te matū, te mīhini, te motuka, te pepa, te rongoā me ētahi atu mara, ka kaweakehia ngā hua ki te United States, Tiamana, Hapani, Korea ki te Tonga, United Arab Emirates, Awherika ki te Tonga, Taiwan me ētahi atu neke atu i te 40 whenua me te rohe.
Te kāpia silicon honohono tauhohenga (SiSiC): Ko te pakeke o Moh he 9.5, he ātete pai ki te horo me te waikura, he ātete pai ki te pakū me te ārai i te waikura. E 4 ki te 5 ngā wā kaha ake i te kāpia silicon honohono nitride. Ko te roa o te mahi he 7 ki te 10 ngā wā roa atu i te rauemi alumina. Ko te MOR o te RBSiC he 5 ki te 7 ngā wā i te SNBSC, ka taea te whakamahi mō ngā āhua uaua ake.
TE TĀKAI:
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.
