Brown Corundum Micropowder Manufacturing Process ndi Quality Control
Yendani mufakitale iliyonse yopangira ma hardware, ndipo mpweya umadzazidwa ndi fungo lodziwika bwino la fumbi lachitsulo, limodzi ndi kugunda kwamphamvu kwa makina opera. Manja a antchito adzapaka mafuta akuda, koma pamaso pawo ufa wonyezimira wa bulauni—brown corundum micropowder—ndi “mano” ofunikira ndi “kuthwa” kwa makampani amakono. Zinthu zolimbazi, zomwe zimadziwika kuti "corundum" ndi anthu ogwira ntchito m'makampani, zimasintha kuchokera ku ore kupita ku ufa wabwino, kuyesa kutentha kwakukulu komanso kulondola.
1. Flames-Chikwi: Njira Yopangira Brown Corundum Micropowder
Brown corundum micropowderimayamba ngati zotupa zopanda pake za bauxite. Musati mupeputse zipolopolo za nthaka izi; ayenera kukhala ore apamwamba kwambiri okhala ndi Al₂O₃ osachepera 85% kuti ayenerere kusungunula. Pamene ng'anjo yosungunula imatsegulidwa, zimakhala zochititsa chidwi kwambiri - kutentha mkati mwa ng'anjo yamagetsi kumakwera kufika pa 2250 ° C. Bauxite, kuphatikizidwa ndi zitsulo zachitsulo ndi coke, imagwera ndi kusungunuka mumoto woyaka kwambiri, kuyeretsa ndi kuchotsa zonyansa, pamapeto pake kupanga midadada wandiweyani wa corundum. Kusankhidwa kwa mtundu wa ng'anjo kumakhalanso ndi zake: ng'anjo yowonongeka imapereka madzi abwino kwambiri komanso chiyero chapamwamba, choyenera pazinthu zabwino; ng'anjo yokhazikika imapereka kutulutsa kwakukulu komanso mtengo wotsika. Opanga nthawi zambiri amasankha malinga ndi zomwe akufuna.
Brown corundummidadada yatsopano kuchokera ku ng'anjo idakali "yoyipa," kutali ndi kukhala ufa wabwino. Kenako, chophwanyiracho chimatenga malo: chopondapo chokhala ndi mano awiri kuti chiphwanye, kuphwanya chochuluka, pamene chophwanyira choyimirira chimachita bwino kuphwanya, ndikuphwanya tinthu tinthu tomwe timagulu ta millimeter. Koma si zokhazo—kupatukana kwa maginito ndi kuchotsa chitsulo n’kofunika kwambiri pa khalidwe. Ikayatsidwa, cholekanitsa chapamwamba kwambiri cha maginito chimatha kuchotseratu zitsulo zilizonse zotsalira pazakuthupi. Olekanitsa maginito amphamvu kwambiri omwe amagwiritsidwa ntchito ndi makampani monga Henan Ruishi amatha kuchepetsa Fe₂O₃ mpaka pansi pa 0.15%, kuyala maziko a pickling yotsatira.
Tanki ya pickling imakhalanso ndi zinsinsi. Njira yothetsera 15-25% ya hydrochloric acid imagwiritsidwa ntchito kwa maola 2-4. Kuphatikizika ndi Zhenyu Grinding's patented "push-pull cleaning" ya Zhenyu, ufawo umagwedezeka ndikutsuka, ndikusungunula zonyansa monga silicon ndi calcium, kupititsa patsogolo chiyero cha ufa wabwino. Gawo lomaliza lowunikira lili ngati "kujambula": zowonetsera zogwedezeka zimapereka kuyang'ana kosalekeza, kulekanitsa tinthu tating'onoting'ono kuchokera ku coarse to fine. Chipangizo chowunikira cha Chongqing Saite Corundum chimaphatikizanso magawo atatu a zowonetsera kuphatikiza ndi theka la gawo, kuwonetsetsa kuti tinthu tating'onoting'ono ting'onoting'ono tayezedwa ndi wolamulira. Ufa wosalala wosefa umalembedwa ngati pakufunika—200#-0 ndi 325#-0 ndizodziwika bwino. Chidutswa chilichonse chimakhala chofanana ngati mchenga, chipambano chenicheni.
2. Kuyang'ana Kwambiri: The Lifeline of Micropowder Quality
Kodi brown corundum micropowder amagwiritsidwa ntchito kuti? Kuyambira kupukuta magalasi a foni yam'manja mpaka kuyika ng'anjo zazitsulo zophulika, ngakhale kuwonongeka kwakung'ono kungayambitse mkwiyo wamakasitomala. Choncho, kulamulira khalidwe ndi gwero nthawi zonse mikangano mu fakitale. Choyamba, taganizirani za mankhwala-Al₂O₃ zokhutira ziyenera kukhala ≥95% (zogulitsa zapamwamba zimafuna ≥97%), TiO₂ ≤3.5%, ndi SiO₂ ndi Fe₂O₃ ziyenera kusungidwa mkati mwa 1% ndi 0.2% motsatira. Akatswiri a labotale amawunika ma spectrometer tsiku lililonse; ngakhale kusinthasintha pang'ono kwa deta kungayambitse kukonzanso kwa gulu lonse.
Kuyesa katundu wakuthupi ndikofanana:
Kulimba kwa Mohs kuyenera kufikira 9.0. Chitsanzo chimakandidwa pa mbale; chizindikiro chilichonse cha kufewa chimatengedwa ngati cholephera.
Kuchulukana kowona kumangokhala 3.85-3.9 g/cm³. Zopotoka zikuwonetsa vuto ndi kapangidwe ka kristalo.
Kuyesa kwa refractory ndikovuta kwambiri-kung'amba ndi ufa utaponyedwa mu ng'anjo ya 1900 ° C kwa maola awiri? Gulu lonse lathetsedwa!
Kufanana kwa tinthu ting'onoting'ono ndikofunikira kwambiri pakupukuta zotsatira. Woyang'anira khalidwe amafalitsa ufa wodzaza spoon pansi pa laser particle size analyzer. Kupatuka kulikonse mu mtengo wa D50 wopitilira 1% kumawonedwa ngati kulephera. Kupatula apo, kukula kwa tinthu ting'onoting'ono kumabweretsa zokanda kapena zigamba pazitsulo zopukutidwa, zomwe zimadzetsa madandaulo kuchokera kwa makasitomala.
Muyezo wadziko lonse wa GB/T 2478-2022, wosinthidwa mu 2022, wasanduka chuma chamakampani. Chikalata cholimba chaukadaulochi chimayang'anira chilichonse kuyambira kapangidwe kake ndi kapangidwe ka kristalo mpaka pakuyika ndi kusungirakobrown corundum. Mwachitsanzo, pamafunika kuti α-Al₂O₃ iwonetse mawonekedwe a kristalo wa trigonal. Kodi mumawona crystallization yosasinthika pansi pa microscope? Pepani, malonda atsekeredwa! Opanga tsopano akuyenera kulembetsa kutentha ndi chinyezi m'nyumba yosungiramo zinthu - powopa kuti ma micropowder anganyowe ndikuphatikizana, kuwononga mbiri yawo.
3. Kusandutsa Zinyalala Kukhala Chuma: Zipangizo Zamakono Zobwezeretsanso Zimaphwanya Vuto Lothandizira
Makampani a corundum akhala akuvutika kwa nthawi yaitali chifukwa cha kuchuluka kwa zinyalala za abrasives ndi mawilo opera, zomwe sizimangotenga malo komanso zimawononga chilengedwe. Komabe, m'zaka ziwiri zapitazi, ukadaulo wa "recycled corundum" watulukira, zomwe zimapangitsa kuti zinthu zotayira zikhale moyo watsopano. Patent yatsopano ku Yingkou, m'chigawo cha Liaoning, yatenganso njira yowonjezereka: choyamba, zinthu zotayidwa za corundum zimapatsidwa "kusamba" kuchotsa zonyansa, kutsatiridwa ndi kuphwanya ndi kupatukana kwa maginito, ndipo potsiriza, pickling yakuya ndi hydrochloric acid. Izi zimachulukitsa kuchotsa zonyansa ndi 40%, kubweretsa magwiridwe antchito azinthu zobwezerezedwanso pafupi ndi za micropowder wa namwali.
Kugwiritsa ntchito zinthu zobwezerezedwanso kukukulirakulira. Mafakitale osakanizidwa amakonda kugwiritsa ntchito ngati dongo la dongo - liyenera kusakanizidwa kukhala zotayidwa, ndipo zinthu zobwezerezedwanso zimapereka mtengo wodabwitsa. Ngakhalenso bwino, njira yobwezeretsanso imachepetsabrown corundumndalama ndi 15% -20%, kupangitsa mabwana kukhala osangalala kwambiri. Komabe, akatswiri odziwa bwino ntchito zamafakitale akuchenjeza kuti: “Kupukuta mwatsatanetsatane kumafuna zinthu zosafunika kwenikweni.
4. Pomaliza: Micropowder, Yaing'ono Monga Iri, Imanyamula Kulemera kwa Makampani
Kuchokera pamoto woyaka moto wa ng'anjo yamagetsi yamagetsi mpaka kung'ung'udza kwa zolekanitsa maginito, kuchokera pakuwotcha kwa akasinja mpaka pamizere yowunikira ya laser particle size analyzers - kubadwa kwa brown corundum micropowder ndi mbiri yaying'ono yamakampani amakono. Ma Patent atsopano, miyezo yatsopano yadziko, ndi ukadaulo wobwezerezedwanso zikupitilira kukankhira denga lamakampani kukhala pamwamba. Kufuna kwamakampani akumunsi kuti azitha kuwongolera bwino kwambiri za mankhwala apamtunda kukupitilira kupititsa patsogolo khalidwe la micropowder. Pamzera wophatikizirapo, matumba a ufa wofiirira amamata ndi kukwezedwa m'magalimoto, kupita kumafakitale m'dziko lonselo. Zitha kukhala zosaimbidwa, koma zimathandizira mphamvu yayikulu ya Made in China, pansi pa kupukuta kwake kowoneka bwino.
