Huruhuru kaolin: te painga, me te whānui

ngā Vata o mullite muka kaolin me whakarōpūtia ngā rite rauemi mātao waiariki. rere ke te reira ātete ki te ahi me te te whakamahia hoki ki te whakaki i te feāvaaki i roto i te aua marae me te tatau hiri mokamoka.

whakaahuatanga

Kei te nuinga o te wā whakatinana Material i te puka o ngā rārangi. Kei te whakaputaina te reira i roto i te tukanga o te rewa waikura silicon me te konumohe i pāmahana teitei i roto i oumu motuhake. huruhuru kaolin mō nga tau maha kaha whakamahia mo te kaupare mātao waiariki o whare, me te outperforms maha atu rauemi. Ahakoa te momo hou o te tahi atu māngai ki ngā āhuatanga rite, kei te hoko i te reira atu rongonui a kitea tona whakamahinga i roto i ngā tono ahumahi. E ohipa te reira whakaaro he waiariki mātao, ruma parariraa, exchangers wera me kapohau. Ko te tino whānui tuhia i roto i te ahumahi. Hoki whakamahia kaolin huruhuru kei roto i te hanga o papa, me te tahi atu tūemi whakarewa.

He tangi nui taumata me te mātao wera, ātete ki te deformation me te wiri kawenga te rauemi. I tua atu, he te tahi atu āhuatanga e he āhuatanga o maha rauemi ki te whakaaro rite miro. E kore te te tikanga tuuraa i pāngia e te pāmahana teitei i roto i te taiao kūpapa oxidizing ranei, e taea te nui haere te taumata o ātete i te whakamahi o te chromium waikura. Ahakoa tenei, i te āhuatanga matua, ko te ki te mau tonu te nui heke i roto i te huru whakaiti i te wera.

painga

Ko pai hoki te hanganga o nga Pads wahia, huinga mātao o oumu, me waihanga taiepa Vata MKRR-130. whakaiti Ko tōna taimaha iti te nui o te wā e hiahiatia ana, me te kaha e hiahiatia ana mō te tāutanga, me te whakaiti utu wahie. E tano ia tapao atu āhuatanga pai:

• E āhuatanga muka tino horoia e ātete tiketike ki te devitrification;
• taumata iti o te haaputuputuraa wera;
• ātete ki waiariki ru;
• tiaki o te āhuatanga taketake i roto i te whakamahi toutou;
• he nui rawa o te mātao tangi;
• E kore te mea pāngia e riri matū matū, kawakore me whakarewa rewa;
• e mangere ki te hinu i runga i te hinu kohuke, me te kohu wai;
• noho tonu ngā āhuatanga hiko noa i pāmahana teitei.

āhuatanga

huruhuru kaolin hanga o alumina whakangutungutu, e hāngai ana nei i runga i kiripaka onepu. I roto i te oumu ore-tango, motuhake rewa te i te pāmahana o 1800 nekehanga. I roto i te rohe rewa tapaea e toru electrodes, i i te pae o to ratou whakapaparanga e rua anake. technique pupuhi te whakamahia mō te ngohe i te rauemi, e hāngai ana ki runga ki te pānga o te mamaoa motuhake whakaratohia e te pēhanga o e pā ana ki 0.7 MPa. Pana pupuha taea te wahi o te tukanga pupuhi katoa. Ka rite ki kia haa uwhi karaihe wai, te uku sima ranei.

Vata kaolin hokona i roto i ngā rārangi o runga ki te 10 mita i roto i te roa, matotoru me te whanui o te 2 cm me te 60 cm, aua. He ngāwari te reira, reira whakarato he pai snug mo tetahi hoahoa. I teie mahana, e ngana ana kaiwhakanao ki te whakapai ake i te rauemi i te tua o ngā wāhanga atu, hoki yttria tauira. whakapiki i tenei te pūmautanga o te muka, ka whakawhānui te whakamahi taea.

Rauemi ātete ki te ahi

rauemi whakangutungutu hanga i nga turanga kohuke, me te he ātete ki te pāmahana teitei, me noho tonu ratou āhuatanga. He mahuinga ia i roto i te ahumahi maitai mo te Māturu, ngā tukanga ahua, me te tahi atu, te hanga o huarahi o tiketike-pāmahana (motors, reactors) me wāhanga mo ratou ratou. I muri te whakamahi i refractories e tonoa mai hoki hangarua.

Nuinga o ngā wā, kua he āhua tapawhā me te taimaha iti, hanga pai ratou mo te ngā ararewa tenei momo o te hua. I tēnei wā, i reira te mea he whakaiti ohie i roto i te hanga o refractories, rite utua atu te aro te ki te hanga o mōtā motuhake me concretes, ātete ki pāmahana teitei.

rauemi whakangutungutu: hokohoko tikanga

rauemi E ratou he kopu uku hanga o borides whakangutungutu, nitrides, waikura, me te whai i te taumata teitei o te inertness matū me te mauroa. Hoki maha whakamahia waro pūhui. pupuri whakangutungutu ratou āhuatanga ka whai wāhi ki te pāmahana i waenganui i 1600 nekehanga me e whakamahia i roto i ngā wāhi maha i reira i reira he he hiahia mo tetahi mahi i roto i te tikanga i homai. E ai ki te tikanga o te hanga hua e wehea ki te maha ngā momo:

• wera-e aki;
• koranu, tukatuka i te rewanga;
• kirihou hanga;
• koranu e hāngai ana i runga i penoshlikera wai;
• tapahia i nga poraka tukatuka toka ranei.
