Njerwa za Alumina Ceramic Liner Zolimba Kwambiri Zolumikizana ndi Magulu

Njerwa za alumina ceramic zomwe sizingawonongeke ndi njira yodzitetezera yomwe imapangidwa makamaka kuti igwiritsidwe ntchito m'malo omwe amagwiritsidwa ntchito kwambiri monga ma ball mills, ma stirries, mapaipi, ndi ma chutes. Mosiyana ndi mbale zachikhalidwe zathyathyathya, njerwa zathu zimakhala ndi malo olumikizirana omwe amatsekedwa ndi makina kudzera m'malo olumikizirana bwino a lilime ndi groove. Kapangidwe kameneka kamachotsa bwino mipata yolunjika pakati pa njerwa, kuteteza matope ndi tinthu tating'onoting'ono kuti tisawononge chipolopolo cha zida. Chofunika kwambiri, chimagawa katundu wokhudzana ndi kugundana mofanana ku njerwa zapafupi, zomwe zimapangitsa kuti denga lonselo lisawonongeke komanso kuti lisagwedezeke. Pophatikizidwa ndi zomatira zamphamvu kwambiri, kapangidwe ka groove komwe kumalumikizidwa ndi groove kamaonetsetsa kuti dengalo likhale lolimba kwambiri ngakhale litazungulira mwachangu kapena kugwedezeka kwambiri, kupereka chitetezo chokhazikika komanso chokhalitsa.

Ponena za magwiridwe antchito a zinthu, njerwa zathu za alumina ceramic liner zimapangidwa kuchokera ku ufa wa α-alumina woyera kwambiri kudzera mu kukanikiza kwa isostatic ndi kutentha kwambiri, wokhala ndi kuchuluka kwa alumina kuyambira 92% mpaka 99% ndipo umasinthidwa mokwanira malinga ndi momwe ntchito ikuyendera. Mwachitsanzo, potengera njerwa za alumina za 95% zomwe zimagwiritsidwa ntchito kwambiri, makhalidwe wamba ndi awa: kuchuluka kwa bulk density ≥ 3.65 g/cm³, kuyamwa madzi < 0.01%, Rockwell hardness HRA ≥ 86, mphamvu yokakamiza ≥ 2000 MPa, mphamvu yopindika ≥ 300 MPa, ndi kulimba kwa kusweka > 3.5 MPa·m½. Mu mayeso wamba a wet abrasion, kutayika kwa unyinji kumakhala kotsika ndi 90% kuposa kwa chitsulo cha manganese, ndipo kuchuluka kwa volumetric clocking nthawi zambiri kumakhala pansi pa 0.02%. Ziwerengerozi si malire a chiphunzitso koma ndi deta yowunikira yokhazikika kuchokera ku dongosolo lathu lowongolera khalidwe, kuonetsetsa kuti gulu lililonse loperekedwa nthawi zonse limasintha kukana kuwonongeka, kukana dzimbiri, komanso kulimba kukhala nthawi yochepa yogwira ntchito komanso kupezeka kwa zida zambiri kwa makasitomala athu.

Masiku ano, njerwa zathu zolumikizirana za alumina ceramic zomwe sizingawonongeke zakhala zikugwiritsidwa ntchito kwambiri m'migodi, simenti, kupanga magetsi, zoumba, ndi mafakitale a mankhwala abwino kuti zigwiritsidwe ntchito pogaya ndi kunyamula zinthu zosiyanasiyana. Kaya kupirira kukanda kwambiri kwa mipira yachitsulo ndi matope mu mphero yokonzanso miyala yachitsulo, kupirira kudula kosalekeza kwa ufa wothamanga kwambiri pazigongono zonyamula mpweya, kapena kukana kuwonongeka kwa asidi m'mapaipi okhuthala, njerwa zolumikizanazi zimasonyeza moyo wautumiki woposa kwambiri wa zipangizo wamba zosagwirizana ndi kuwonongeka.
