Nchifukwa chiyani chitoliro cha alumina ceramic chili cholimba kwambiri?

Monga mtundu wa zinthu zogwira ntchito bwino kwambiri, chubu cha alumina ceramic chagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Kukana kwake kuvala bwino kumachitika makamaka chifukwa cha zinthu zake zoyera kwambiri za alumina komanso njira yapadera yopangira. Izi ndi kusanthula mwatsatanetsatane kwa kukana kwa kuvala kwa machubu a alumina ceramic.

Gawo lalikulu lamachubu a alumina ceramicndi alumina, yomwe nthawi zambiri imakhala yoyera kuposa 90%. Alumina yoyera kwambiri imapatsa zipangizo za ceramic mphamvu zabwino kwambiri zakuthupi ndi zamakemikolo, makamaka pankhani yolimbana ndi kutopa. Malinga ndi zomwe zapezeka, kukana kwa kutopa kwa ziwiya za alumina zoyera kwambiri ndikofanana ndi kuwirikiza 266 kuposa chitsulo cha manganese ndi kuwirikiza 171.5 kuposa chitsulo cha chromium chopangidwa ndi chitsulo. Izi zikutanthauza kuti pansi pa mikhalidwe yofanana yogwirira ntchito, kugwiritsa ntchito zida za alumina zoyera kwambiri zomwe sizingawonongeke ndi ceramic kumatha kukulitsa moyo wa zidazo, osachepera kakhumi.

Kuuma kwa machubu a alumina ceramic ndi okwera kwambiri, pambuyo pa diamondi, kuposa zipangizo zachikhalidwe monga chitsulo chosatha kutha ndi chitsulo chosapanga dzimbiri. Kuuma kwakukulu kwa machubu a alumina ceramic kumapangitsa kuti akhale abwino kwambiri polimbana ndi kutha ndi kukanda. Zinthu zomwe zimakhala ndi tinthu tating'onoting'ono tambiri zikanyamulidwa mupaipi, monga phulusa, malasha ophwanyidwa, ufa wosalala wa mchere, michira, simenti, ndi zina zotero, kuuma kwakukulu kwa chitoliro cha alumina ceramic kumatha kukana kutha kwa zipangizozi, motero kukulitsa moyo wa ntchito yapaipi.

Chubu cha alumina ceramic ndi chinthu cha ceramic chomwe chimapangidwa ndi njira yapadera yokanikiza njira yosiyana. Njirayi imapangitsa kuti kapangidwe ka kristalo ka ceramic kakhale kofanana ndipo kamawonjezera kukana kwake kukalamba. Nthawi yomweyo, chubu cha alumina ceramic chimapangidwa chonse, ndipo matopewo ndi osapindika, zomwe zimawonjezeranso mphamvu yake yolimbana ndi kukalamba. Kuyeseraku kukuwonetsa kuti moyo wa chubu cha alumina ceramic chokhala ndi makulidwe omwewo ukhoza kuwonjezeka kasanu poyerekeza ndi pepala la ceramic.

Kukana kwa alumina ceramic chubu kumapangitsa kuti igwiritsidwe ntchito kwambiri m'mafakitale ambiri. Mwachitsanzo, m'mapayipi otulutsa phulusa m'mafakitale opangira magetsi opangidwa ndi malasha, machubu a alumina ceramic amatha kukana kutopa kwa ufa wa malasha ndi phulusa ndikuwonjezera moyo wa zidazo. Kuphatikiza apo, machubu a alumina ceramic amagwiranso ntchito bwino m'migodi, m'mafakitale a simenti ndi nthawi zina pomwe zinthu zopera ziyenera kunyamulidwa.

Poyerekeza ndi zipangizo zachikhalidwe zosatha kutha, machubu a alumina ceramic ali ndi kutha kutha bwino. Mwachitsanzo, poyerekeza ndi chitsulo chosatha kutha ndi chitsulo chosapanga dzimbiri, machubu a alumina ceramic ali ndi kuuma kwambiri komanso kutha kutha bwino. Poyerekeza ndi chitoliro cha miyala yopangidwa ndi miyala, chitoliro cha alumina ceramic chili ndi kulemera kochepa komanso kulemera kopepuka, ndipo n'chosavuta kuyika, kunyamula ndi kukonza. Ubwino uwu umapangitsa machubu a alumina ceramic kukhala chinthu chodziwika bwino chotha kutha m'magawo ambiri.

Mwachidule, machubu a alumina ceramic akhala akugwiritsidwa ntchito kwambiri m'mafakitale ambiri chifukwa cha zinthu zake zoyera kwambiri za alumina, mawonekedwe ake olimba kwambiri, njira yapadera yopangira komanso kukana kuvala bwino. Kukana kwake kuvala bwino sikuti kumangowonjezera moyo wa zidazo, komanso kumawonjezera magwiridwe antchito a zidazo, komanso kumabweretsa phindu lalikulu pazachuma pakupanga mafakitale.
