Paipa uku Silicon carbide ātete-mau
Ukume karāhe hākawa: Ko te pakeke o Moh he 9.0~9.2, 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 karāhe hākawa e honoa ana ki te nitride. Ko te roa o te ora 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.
Ko te ātete kakahu o te silicon carbide, he mea hanga mai i te silicon carbide me te waro i te pāmahana teitei, nō tētahi momo hua silicon carbide. He whānuitia te whakamahinga o ngā wāhanga ātete kakahu o te silicon carbide i roto i te keri, te kuru i ngā konganuku, te tirotiro me te kawe i ngā wai tino kakahu, tino waikura, he tino pai hoki mō ngā hua miihini me ngā whakaritenga hiri teitei, pērā i te papu pēhanga teitei, te papu aukume me ētahi atu. He momo rauemi ātete kakahu hou. Ko te pūkaha ātete kakahu o te silicon carbide e honoa-tauhohenga ana he āhuatanga o te pakeke teitei, te ātete kakahu teitei, te ātete pānga, te ātete pāmahana teitei, te ātete waikura waikawa me te kawakore me ētahi atu, ā, ko te roa o te ora ratonga tūturu he neke atu i te 6 ngā wā i te polyurethane. He tino pai mō te whakahaere i te whakarōpūtanga, te kukū me te maroke o ngā rauemi kaha me te matotoru, kua angitu te whakamahi i roto i te maha o ngā maina. Ko tā mātou kamupene he kaiwhakarato hua uku ātete kakahu silicon carbide ngaio, ko te pakeke tuarua anake ki te taimana, me te ātete kakahu teitei, ngā āhuatanga roa o te ora ratonga. Ko te paipa ātete kakahu me te tuke i hangaia me te arai ātete kakahu silicon carbide, ko tōna matotoru arai uku he 6-35mm, ko te hanganga ko te tāuta i te ngongo uku kua oti te whakakorikori ki roto i te maitai taurite. he ngongo, me te kāpia i waenganui. Ko ngā āhuatanga o ngā paipa uku ātete-mau e whai ake nei, ki te whakaritea ki ngā paipa kōhatu-maka o mua, ngā paipa maitai whakarewa koranu ātete-mau me ngā paipa hiato uku.
He tino pai te ātete o te karawiti silicon here tauhohenga (RBSC) ki te kakahu, he pai ngā āhuatanga i ngā pāmahana teitei, he pai te ātete ki te horo me te haehae, ka taea te whakamahi i ēnei āhuatanga i roto i ngā momo tono pēnei i ngā raina paipa, te tuke uku, ngā pūwero rehu, ngā pūwero pupuhi me ngā wāhanga hydrocyclone.
He roa ake te ora o ngā arai ZPC i ngā arai tāera me ngā arai whakarewa. He ātete ngā uku silicon carbide ZPC ki ngā ru wera me te ātete ki te pakū, ā, ka roa ake te wā oma me te whakaiti i te wā kore mahi.
Ko te uku silicon carbide honohono tauhohenga (RBSIC) he rauemi ātete kakahu tino pai, he mea tino pai mō te mahi whakakoi kaha, ngā matūriki taratara, te whakarōpūtanga, te kukū, te whakamaroke me ētahi atu mahi. Nā ngā āhuatanga o runga ake nei, ko teTuke whakarara / ngongo whakarara RBSiC / SiSiC silicon carbideKa taea te tiaki i te wāhanga mai i te kakahu tiketike me te pāmahana kia roa ai te ora o te taputapu.

Āhua mahi o te paipa ātete-kākahu o te silicon carbide uku
Ko ngā āhuatanga matua o te silicon carbide ko:
- iti te mātotoru
- Te kaha nui
- He kaha pai mō te pāmahana teitei (He hononga tauhohenga)
- Ātete waikura (Hoatu tauhohenga)
- He ātete pai rawa atu ki te ru wera
- Te pakeke teitei me te ātete kakahu
- He ātete matū tino pai
- He iti te horapa wera me te kawe wera teitei
Ko ngā tono matua mō te silicon carbide ko:
He nui ake te whakamahinga mō te mahi me te kakahu i te pāmahana iti i te mahi pāmahana teitei. Ko ngā tono SiC pērā i ngā werohanga onepu, ngā hiri papu wai motuka, ngā peera, ngā wāhanga papu, me ngā mate extrusion e whakamahi ana i te pakeke teitei, te ātete ki te kukū, me te ātete ki te waikura o te carbide o te silicon.
- Ngā wāhanga tāpine pumau me ngā wāhanga e neke ana
- Ngā hiri, ngā peera, ngā vane papu
- Ngā wāhanga takirere pōro
- Ngā pereti kakahu
- Taonga oumu
- Ngā whakawhiti wera
- Ngā taputapu tukatuka anga haurua-arataki
Te ahumahi whakarewa me te hiko: Ko te take i honoa ai ēnei ahumahi e rua nā te mea he hononga kei waenganui i ēnei ahumahi e rua.
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.
