Chophimba cha Alumina Ceramic chosagwira ntchito pa Zida Zomera za Simenti

Pakupanga simenti, zida monga mapaipi onyamula zinthu, nyumba zolekanitsa, ma cyclone, ndi ma chute zimakhala ndi mphamvu yothamanga kwambiri komanso kuwonongeka kwa nthawi yayitali, zomwe zimapangitsa kuti zitsulo ziwonongeke mwachangu komanso kuti ndalama zokonzera ziwonjezeke nthawi yogwira ntchito. Kugwiritsa ntchito alumina ceramic lining yosatha kutha kumawonjezera nthawi yogwira ntchito. Lining iyi imapangidwa kudzera mu kutentha kwambiri, yokhala ndi alumina yosachepera 92%, kuchuluka kwa alumina ≥3.60 g/cm³, Rockwell hardness (HRA) pamwamba pa 85, ndi kuchuluka kwa kuwonongeka kosakwana 0.1 cm³ (yoyesedwa malinga ndi GB/T 8489-2006).

Poyerekeza ndi mbale zachitsulo zomwe sizingawonongeke (monga NM400), alumina ceramic inlay imawonetsa kukana kuwonongeka kochulukirapo ka 5-8, komanso kukana kupsinjika pang'ono pamwamba (pafupifupi 0.2-0.3 pansi pa nyengo youma), kuchepetsa kuuma kwa zinthu ndi kutsekeka. Matailosi a ceramic amamangiriridwa kukhoma lamkati la chipangizocho pogwiritsa ntchito epoxy resin kapena guluu wosapangidwa ndi zinthu zachilengedwe, ndi kutentha kwa ntchito kuyambira -50°C mpaka 300°C komanso kupirira kwakanthawi kochepa mpaka 500°C. Pansi pa mikhalidwe yanthawi zonse ya chomera cha simenti, ceramic inlay imawonjezera moyo wa ntchito ya chute kuyambira miyezi 6 mpaka miyezi yoposa 36.

Chipindachi chagwiritsidwa ntchito bwino pazinthu zofunika kwambiri monga ma chute odyetsera mill, ma vane otsogolera olekanitsa, ma cyclone cones, ndi mapaipi oyendera a clinker m'mafakitale a simenti. Deta ya m'munda ikuwonetsa kuti pansi pa kukula kwa tinthu tating'onoting'ono ta 30 mm ndi liwiro la 15 m/s, patatha miyezi 12 yogwira ntchito mosalekeza, kuya kwa kusweka kwa matailosi a ceramic ndi 0.2–0.5 mm yokha, ndipo nthawi yosamalira zida imakulitsidwa mpaka kanayi kuposa nthawi yoyambirira. Imapezeka m'ma mbale a ceramic kapena ma tile a mosaic, chipindacho chimasinthasintha kuti chigwirizane ndi zida zokhala ndi ma curvature osiyanasiyana komanso mawonekedwe ake.

Kutsatsaalumina ceramic clair yolimba mu zida zaukadaulo za simentiKumachepetsa kugwiritsa ntchito zida zosinthira komanso kutayika kwa nthawi yogwira ntchito, zomwe zimapangitsa kuti mizere yonse yopangira igwire ntchito bwino. Mukakhazikitsa, onetsetsani kuti pamwamba pa substrate ndi paukhondo komanso palibe mafuta; nthawi yothira zomatira iyenera kukhala osachepera maola 24 (pa 25°C). Pa ngodya zogunda zoposa 45° pamalo ogwetsa zinthu, gawo losungiramo zinthu limalimbikitsidwa kuti liwongolere kukana kugwedezeka. Ukadaulo uwu waphatikizidwa mu miyezo yambiri yoteteza kuvulala mkati mwa makampani a simenti.
