Menene corundum mullite sinter plate?

Farantin sinter kayan aiki ne da ake amfani da shi don ɗauka da ɗaukar tayin yumbun da aka kora a cikin tukunyar yumbu.Ana amfani da shi musamman a cikin yumbun kiln a matsayin mai ɗaukar kaya, daɗaɗɗen zafi da isar da yumbun da aka ƙone.Ta hanyar shi, yana iya inganta saurin tafiyar da zafi na farantin karfe, sanya samfuran sinadarai su zama mai zafi sosai, rage yawan amfani da makamashi yadda ya kamata da saurin saurin harbi, inganta fitarwa, ta yadda wannan kiln ɗin ya kori samfuran mara launi da sauran fa'idodi.

Corundum mullite kayan yana da babban juriya na girgiza zafin zafi da ƙarfin zafin jiki mai ƙarfi, da kwanciyar hankali mai kyau na sinadarai da juriya.Saboda haka, ana iya amfani da shi akai-akai a yanayin zafi mafi girma, musamman don maɗaukaki na magnetic, capacitors na yumbu da yumbu masu rufewa.

Kayayyakin sinadarai sune samfuran laminated sintering.Kowane Layer na farantin sintering tare da nauyin samfur yana da kusan 1kg, gabaɗaya l0 Layer, don haka faranti na iya ɗaukar matsakaicin matsakaicin fiye da kilogram goma.A lokaci guda kuma, don ɗaukar matsawa lokacin motsi da jujjuyawar kayan lodi da saukarwa, amma kuma yawancin yanayin sanyi da zafi, sabili da haka, amfani da yanayin yana da wahala sosai.

Ba tare da la'akari da hulɗar abubuwa guda uku ba, alumina foda, kaolin da zafin jiki na calcination duk suna shafar juriya na zafi da rarrafe.Rashin juriya na thermal shock yana ƙaruwa tare da ƙari na alumina foda, kuma yana raguwa tare da karuwar zafin wuta.Lokacin da abun ciki na kaolin ya kasance 8%, ƙarfin juriya na thermal shock shine mafi ƙanƙanta, sannan abun ciki na kaolin na 9.5%.Creep yana raguwa tare da ƙari na alumina foda, kuma creep shine mafi ƙasƙanci lokacin da abun ciki na kaolin ya kasance 8%.Matsakaicin zafin jiki shine 1580 ℃.Domin yin la'akari da thermal girgiza juriya da creep juriya na kayan, da mafi kyaun sakamakon da aka samu a lokacin da alumina abun ciki ne 26%, kaolin ne 6.5% da calcination zafin jiki ne 1580 ℃.

Akwai tazara tsakanin barbashi corundum-mullite da matrix.Kuma akwai wasu tsage-tsafe a kusa da ɓangarorin, waɗanda ke haifar da rashin daidaituwa na ƙimar haɓakar haɓakar thermal da na roba tsakanin barbashi da matrix, wanda ke haifar da microcracks a cikin samfuran.Lokacin da faɗaɗa ƙididdiga na barbashi da matrix ba su daidaita ba, tarawa da matrix suna da sauƙin rabuwa lokacin zafi ko sanyaya.An kafa rata tsakanin su, wanda ya haifar da bayyanar microcracks.Kasancewar waɗannan ƙananan ƙwayoyin cuta za su haifar da lalacewa na kayan aikin injiniya na kayan aiki, amma lokacin da kayan da ke cikin yanayin zafi.A cikin rata tsakanin tarawa da matrix, zai iya taka rawa na yanki mai ɓoyewa, wanda zai iya ɗaukar wani danniya kuma ya guje wa damuwa da damuwa a tip.A lokaci guda, ƙwanƙwasa zafin zafi a cikin matrix zai tsaya a rata tsakanin sassan da matrix, wanda zai iya hana yaduwar fashewa.Don haka, an inganta juriya na thermal shock na kayan.
