Inqubo Yokukhiqiza Impuphu Ye-Brown Corundum Micropowder Nokulawula Ikhwalithi
Ngena kunoma iyiphi ifektri yokucubungula ihadiwe, bese umoya ugcwala iphunga elihlukile lothuli lwensimbi, oluhambisana nokuvunguza okukhulu kwemishini yokugaya. Izandla zezisebenzi zigcotshwe ngamafutha amnyama, kodwa phambi kwazo kukhona impuphu ensundu ekhazimulayo—i-corundum micropowder ensundu—“amazinyo” kanye “nohlangothi olubukhali” olubalulekile embonini yanamuhla. Le nto eqinile, eyaziwa ngokuthi “i-corundum” ngabantu abangaphakathi embonini, iguqulwa kusuka ensimbini ibe yimpuphu ecolekileyo, ukuhlolwa kokubili kokushisa okuphezulu kanye nokunemba.
1. Amalangabi Angamadigri Ayizinkulungwane: Inqubo Yokukhiqiza I-Brown Corundum Micropowder
I-micropowder ye-corundum ensunduIqala njengezigaxa ze-bauxite ezingatheni. Ungazithathi kalula lezi zigaxa zomhlaba; kumele zibe yi-ore yezinga eliphezulu enokuqukethwe kwe-Al₂O₃ okungenani okungu-85% ukuze ifanelekele ukuncibilikiswa. Lapho nje isithando sokuncibilikisa sivuleka, kuba umbono omangalisayo ngempela—izinga lokushisa ngaphakathi kwesithando sikagesi se-arc liyakhuphuka, lifinyelele ngaphezu kuka-2250°C. I-Bauxite, ehlanganiswe nezingcezu zensimbi kanye ne-coke, iyawa futhi incibilike emalangabini amakhulu, ihlanze futhi isuse ukungcola, ekugcineni yakhe amabhlogo e-corundum ansundu aqinile. Ukukhetha uhlobo lwesithando nakho kuyazifanela: isithando sokuncibilika sinikeza ukugeleza okuhle kakhulu kanye nobumsulwa obuphezulu, esifanele imikhiqizo emihle; isithando sokuncibilika sinikeza umkhiqizo ophezulu kanye nezindleko eziphansi. Abakhiqizi bavame ukukhetha ngokusekelwe ekufuneni.
I-corundum ensunduAmabhlogo amasha avela esithandweni asemane nje “ayi-roughs,” hhayi ukuba yimpuphu ecolekile. Okulandelayo, i-crusher ithatha izintambo: i-roller crusher enamazinyo amabili yokuchoboza okuqinile, iphula inqwaba, kuyilapho i-vertical impact crusher yenza ukuchoboza okuhle, iphula izinhlayiya zibe yizingcezu ezinobukhulu obungamamilimitha. Kodwa akusikho konke lokho—ukuhlukaniswa kwamagnetic nokususwa kwensimbi kubalulekile ukuze kube nekhwalithi. Uma ivuliwe, i-high-gradient magnetic separator ingasusa ngokuphelele noma yikuphi ukungcola kwensimbi okusele ezintweni. Ama-magnetic separator anamandla aphezulu asetshenziswa izinkampani ezifana ne-Henan Ruishi anganciphisa i-Fe₂O₃ ibe ngaphansi kuka-0.15%, abeke isisekelo sokucola okulandelayo.
Ithangi lokukhuhla liphinde libe nezimfihlo. Isixazululo se-hydrochloric acid esingu-15%-25% sisetshenziswa amahora angu-2-4. Uma sihlanganiswe nedivayisi yokuhlanza enelungelo lobunikazi ye-Zhenyu Grinding ethi “push-pull cleaning device”, impuphu iyanyakaziswa futhi igezwe, ichithe ukungcola okufana ne-silicon ne-calcium, okuthuthukisa ubumsulwa bempuphu ecolekile. Isinyathelo sokugcina sokuhlola sifana “ne-draft”: izikrini ezidlidlizayo zinikeza ukuhlolwa okuqhubekayo, okuhlukanisa izinhlayiya ezincane kusukela kokukhulu kuya kokukhulu. Idivayisi yokuhlola enelungelo lobunikazi ye-Chongqing Saite Corundum ifaka ngisho nezendlalelo ezintathu zezikrini kanye nesikrini sengxenye, okuqinisekisa ukusatshalaliswa kosayizi wezinhlayiya kunembile njengokungathi kulinganiswa ngerula. Impuphu ecolekile ehlungiwe ibe isilebula njengoba kudingeka—200#-0 kanye no-325#-0 yizincazelo ezivamile. Inhlayiya ngayinye ifana njengesihlabathi, impumelelo yangempela.
2. Ukuhlolwa Okuhle Kakhulu: Umzila Wokuphila Wekhwalithi Ye-Micropowder
Isetshenziswa kuphi i-corundum micropowder ensundu? Kusukela ekupholisheni ingilazi yeselula kuya ezitsheni zomlilo zensimbi, ngisho nokuwohloka okuncane kokusebenza kungaholela ekuthukutheleni kwamakhasimende. Ngakho-ke, ukulawulwa kwekhwalithi kuyimbangela eqhubekayo yokungezwani efektri. Okokuqala, cabanga ngokwakheka kwamakhemikhali—okuqukethwe kwe-Al₂O₃ kumele kube ngu-≥95% (imikhiqizo ephezulu idinga u-≥97%), i-TiO₂ ≤3.5%, kanye ne-SiO₂ kanye ne-Fe₂O₃ kumele kugcinwe ngaphakathi kuka-1% no-0.2% ngokulandelana. Ochwepheshe belabhorethri baqapha i-spectrometer nsuku zonke; ngisho nokushintshashintsha okuncane kwedatha kungaholela ekusetshenzisweni kabusha kweqoqo lonke.
Ukuhlolwa kwempahla ebonakalayo nakho kunzima kakhulu:
Ubulukhuni bukaMohs kumele bufinyelele ku-9.0. Isampula iyaklwejwa epuletini lokubhekisela; noma yiluphi uphawu lokuthamba lubhekwa njengokwehluleka.
Ubuningi bangempela bukhawulelwe ku-3.85-3.9 g/cm³. Ukuphambuka kubonisa inkinga ngesakhiwo sekristalu.
Ukuhlolwa kokungawuvivinyi umoya kudinga kakhulu—ukuqhekeka kanye nempuphu ngemva kokuphonswa esithandweni somlilo esingu-1900°C amahora amabili? Lonke iqembu liyasuswa!
Ukufana kosayizi wezinhlayiya kubalulekile emiphumeleni yokupholisha. Umhloli wekhwalithi usakaza isipuni esigcwele sempuphu ngaphansi kwe-laser particle size analyzer. Noma yikuphi ukuphambuka enanini le-D50 elidlula u-1% kubhekwa njengokwehluleka. Phela, usayizi wezinhlayiya ongalingani uzoholela ekuklwebhekeni noma kuma-patches ebusweni bensimbi obupholishiwe, okuholela ekukhonondeni okuvela kumakhasimende.
I-GB/T 2478-2022 ejwayelekile kazwelonke, ebuyekezwe ngo-2022, isibe yinsimbi embozwe embonini. Lo mbhalo wobuchwepheshe obukhulu ulawula konke kusukela ekwakhekeni kwamakhemikhali kanye nesakhiwo sekristalu kuya ekupakishweni nasekugcinweni kwe-i-corundum ensunduIsibonelo, kudinga ukuthi i-α-Al₂O₃ kumele ibonise isimo sekristalu esijwayelekile se-trigonal. Ingabe kukhona ukwakheka kwekristalu okungafani ngaphansi kwe-microscope? Uxolo, umkhiqizo uzogcinwa! Abakhiqizi manje sekufanele babhalise amazinga okushisa kanye nomswakama wendlu yokugcina izinto—ngokwesaba ukuthi ama-micropowders azomanziswa futhi ahlangane ndawonye, onakalise idumela lawo.
3. Ukuguqula Imfucuza Ibe Yingcebo: Ubuchwepheshe Bokuvuselela Buphula Inkinga Yezinsizakusebenza
Imboni ye-corundum ibilokhu ihlushwa ukuqongelela kwezinto zokukhuhla imfucuza kanye namasondo okugaya, okungagcini nje ngokuthatha isikhala kodwa futhi kungcolisa imvelo. Kodwa-ke, eminyakeni emibili edlule, ubuchwepheshe "be-corundum obusetshenzisiwe" buvele, bunikeza izinto ezilahliwe ithuba elisha lokuphila. Ilungelo lobunikazi elisha e-Yingkou, eSifundazweni saseLiaoning, lithathe isinyathelo sokuvuselela kabusha: okokuqala, imikhiqizo ye-corundum elahliwe inikezwa "ibhavu" lokususa ukungcola, kulandelwe ukuchotshozwa kanye nokuhlukaniswa kwamagnetic, futhi ekugcineni, ukuhluzwa okujulile nge-hydrochloric acid. Le nqubo yandisa ukususwa kokungcola ngo-40%, okwenza ukusebenza kwezinto ezisetshenzisiwe kufane nokwe-micropowder emsulwa.
Ukusetshenziswa kwezinto ezisetshenzisiwe nakho kuyanda. Izimboni ezisebenzisa i-refractory zithanda ukuyisebenzisela ubumba lwe-taphole—kufanele luxutshwe nezinto ezisetshenziswayo, futhi izinto ezisetshenzisiwe zinikeza ukusebenza kahle okukhulu kwezindleko. Okungcono nakakhulu, inqubo yokuvuselela inciphisai-corundum ensunduizindleko ngo-15%-20%, okwenza abaphathi bajabule kakhulu. Kodwa-ke, osomabhizinisi abangochwepheshe bayaxwayisa: “Ukupholisha kahle kudinga izinto ezisezingeni lokuqala ezihlanzekile. Uma ngisho nokungcola okuncane kuhlanganiswa nezinto ezisetshenziswe kabusha, ubuso obubonakalayo buzobonakala ngokushesha!”
4. Isiphetho: I-Micropowder, Nakuba Incane Kangaka, Ithwala Isisindo Semboni
Kusukela emalangabini avuthayo ezitofu zikagesi ze-arc kuya ekuvunguzeni kwezihlukanisi zamagnetic, kusukela ekuqhutshweni kwamatangi okugaya kuya emigqeni yokuskena yabahlaziyi bosayizi wezinhlayiya ze-laser—ukuzalwa kwe-brown corundum micropowder kuyinto encane kakhulu embonini yanamuhla. Amalungelo obunikazi amasha, amazinga amasha kazwelonke, kanye nobuchwepheshe obusetshenzisiwe kuyaqhubeka nokuphakamisa uphahla lwemboni. Isidingo sezimboni ezingezansi sokunemba kokwelashwa kwendawo okucishe kube sezingeni eliphezulu siyaqhubeka nokuphakamisa ikhwalithi ye-micropowder. Emgqeni wokuhlanganisa, izikhwama zempuphu ensundu zivalwa futhi zilayishwa emalolini, ziyiswa ezimbonini kulo lonke izwe. Zingase zingadunyiswa, kodwa zisekela amandla angaphakathi e-Made in China, ngaphansi kobuso be-polish yayo engaphezulu.
