Ngā Arai Paipa Ātete-Pakarukaru – Uku Arumina
Ngā Arai Ukume Arumina – Ātete ki te Waro
He rauemi utu iti te konumohe, ā, he whānui te whakamahinga i roto i te whānau uku miihini. Kua whakawhanakehia, kua arotauhia hoki ngā uku konumohe kia tino ātete ki te kakahu me te waikura. Ko te matotoru, te pakeke rite ki te taimana, te hanganga pai o te kōpura me te kaha miihini pai rawa atu, koinei ngā āhuatanga ahurei e pai ai te whakamahi mō te whānuitanga o ngā tono uaua. He rite ngā whakamahinga o te uku ki te papa whakarewa engari he nui ake te ātete ki te kakahu i roto i ngā tono tere teitei me te ātete pānga i roto i ngā pūnaha tino hihiri.
He kupu whakataki mō te tāera ā-aumina hei arai ā-hurihuri ātete-kakahu
Ko te arai kakahu konumohe tētahi o ngā rauemi ātete ki te haukū rongonui o te umanga, he āhua ātete ki te haukū, he utu whai hua, he pakeke teitei. Ko ngā raupapa uku chemshun ātete ki te haukū he ātete pāmahana teitei tae atu ki te taera uku konumohe, ngā wahi arai uku me te whāriki taera hexagonal, te rango uku, ngā uku whakaroa porotaka me ētahi atu. He ngāwari te tāuta i ēnei arai uku ātete ki te haukū me te kapia epoxy, te sima, ko ētahi wahi mosaic he rauemi haukū pai rawa atu mō te whakamomona i roto i te rau rapa. Ko te arai taera uku ka taea te whakarewa hei arai kakahu noa i whakaurua penei:
>> Ngā āhuatanga o te raina kakahu Alumina:
Te pakeketanga teitei
Te ātete pai rawa atu ki te pakū
Te ātete ki te waikura me te matū
Mama te taumaha
Ka taea te whakamahi i roto i ngā momo otinga whakakorenga ā-ahumahi katoa
>> Rahi e wātea ana (Roa*whānui*matotoru):

| 120*80*20mm |
| 228*114*25mm |
| 114*114*25mm |
| He nui ake ngā rahi me te rahi kua whakaritea. Ka taea te whakamahi i te koeko maitai me te tokotoko uku hei whakarewa mā ngā uku Chemshun. |

Mēnā he hiahia mō te raina haurua uku chemshun, ngā arai ātete ki te kakahu, te hoahoa o te raina haurua, te tiaki rānei, tēnā whakapā mai ki a mātou, ā, mā mātou e tuku atu ki a koe te hua tino tika me te ratonga pai rawa atu. Tukutuku: www.chemshun.com Waea: +86-799-6790781
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.
