Tirohia te ataata hua i runga i te paetukutuku:
He tino pai te tiaki i ngā arai uku ātete-kakahu me te ātete-pahū. He mea hanga motuhake mō te whakamahi i ngā wāhi katoa he raruraru te kakahu me te pahū, ka whakaitihia e ngā arai ZPC® te wā kore mahi me te tiaki. He tino ātete ngā arai uku SiC ki ngā pānga pahū o ngā rauemi papatipu pērā i te silica, te ore, te karāhe, te para, te pungarehu rere, te kōhatu, te waro, te kōka, te kai, te witi, te tongi, te tote me ētahi atu rauemi tino pahū.
He pai ngā arai ātete ki te pakū me te kakahu mai i Zhongpeng mō ngā ahumahi maha. Kei roto i ngā kaihoko mai i te ahumahi paura ki ngā ahumahi waro, hiko, maina me te kai, kei reira ngā pūwero FGD kua whakaaetia kia whakamahia i roto i te China Electric Power Group. Kei te hokohokohia ngā arai ātete kakahu ZPC puta noa i te United States, Canada, Ahitereiria, Mexico, Awherika ki te Tonga, me ētahi atu. He pai mō ngā wāhanga arai e ngawari ana ki te pakū nui i roto i ngā mahi whakahaere rauemi tipu me te tukatuka. He whai hua ngā arai, ngā pereti me ngā poraka SiC i roto i ngā tono pēnei i ngā paipa, ngā tī, ngā tuke, ngā wehewehe, ngā awhiowhio, ngā silo, ngā puranga, ngā awa raima me te maitai, ngā awaawa, ngā impeller me ngā kaiwhakaoho, ngā mata pā me ngā anga pā, ngā tīwiri kawe, ngā kawe mekameka, ngā whakaranu, ngā mea pani; i ngā wāhi katoa he raruraru te pakū i puta mai i te waku.
He taera ātete ki te pakaru, hei ārai i te pakaru, te pānga me te waikura o te kiritaki. Mā te whakamahi i ngā arai ātete ki te pakaru ZPC SiC ki ngā wāhanga raruraru ka nui ake te penapena nā te mea he roa ake te ora o ā rātou mahi. Ka tino heke te utu mō ngā wāhanga whakakapinga, te wā kore mahi, te horoi i te tipu me te utu o ngā mahi tiaki. Mā ngā penapena ka utua ngā arai me te tāutanga i roto i te wā poto.
He momo rauemi hangarau-teitei hou te pūwero silicon carbide sic o te ao, ā, he ātete ki te kakahu. I hangaia ki te paura silicon carbide parakore-teitei, te pango waro pāmahana-teitei me ngā mea here, mā te ringihanga, te whakakorenga, te sintering, me te tango onepu, he mea hanga ki te hua kakahu-teitei hiato.
Kei te whakamahia i tēnei wā hei pūwero i roto i ngā taputapu keri, pērā i te parahi, te koura, te rino, te nikara me ētahi atu i roto i ngā konganuku kore-ferrous. He nui te ātete ki te kakahu, he 10 ngā wā te roa o te ora kakahu i ngā pūwero maitai tuku iho me ngā pūwero alumina.
1. Te whakamahinga o te sic bushing i roto i te umanga keri
Mō te whakakī maina, he nui te pakaru o te paipa kawe paura kukū me ngā para. Ko te roa o te ora o te paipa kawe paura konganuku i whakamahia i mua he iti iho i te kotahi tau, ā, i nāianei ka taea e ngā pūwero silicon carbide te whakanui ake i te roa o te ora neke atu i te 10 ngā wā.
2. He aha i whānuitia ai te whakamahinga o ngā arai silicon carbide i roto i te umanga keri?
Nā te ātete o ngā ngongo uku ki te kakahu, e whai ake nei he whakatairite i te ātete o ngā ngongo uku me ētahi atu rauemi.

5. Hononga pūwero carbide silicon
（1）Mēnā ka whakamahia ngā paipa ngāwari hei hono i ngā paipa tāutanga, me whakarite kia ōrite te roa o te whakaurunga o ngā pito e rua o te ringaringa paipa ngāwari. Me hanga te āputa whānui i runga i ngā āhuatanga o te rohe, i ngā whakaritenga rānei a te tari hoahoa.
（2）Ina whakamahia ana te hononga flange, me rite te mata o te flange ki te mata o te pito o te paipa hiato.
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.
