Inqubo Yokukhiqiza I-Corundum Micropowder kanye Nokulawulwa Kwekhwalithi
Hamba uye kunoma iyiphi imboni yezingxenyekazi zekhompuyutha, futhi umoya ugcwele iphunga elihlukile lothuli lwensimbi, elihambisana nokukhala kwemishini yokugaya. Izandla zezisebenzi zigcotshwe ngamafutha amnyama, kodwa impushana ensundu ecwebezelayo phambi kwazo—brown corundum micropowder—“amazinyo” kanye “nonqenqema olubukhali” lwemboni yesimanje. Lesi sici esiqinile, esivame ukubizwa ngokuthi "i-corundum" ngabangaphakathi embonini, sishintsha kusuka ku-ore kuya kumpushana ocolile, ukuhlolwa kokubili kokushisa okuphezulu nokunemba.
1. Amalangabi eziqu eziyinkulungwane: Inqubo Yokukhiqiza Ye-Brown Corundum Micropowder
I-brown corundum micropowderiqala njengezigaxa ezingenakuqhathaniswa ze-bauxite. Ungazibukeli phansi lezi zigaxa zomhlaba; kufanele kube ore bezinga eliphezulu nokuqukethwe kwe-Al₂O₃ okungenani okungu-85% ukuze bafanelekele ukuncibilikiswa. Lapho nje isithando somlilo esincibilikisa sivuleka, kuwumbono omangalisa ngempela—izinga lokushisa ngaphakathi kwesithando somlilo esincibilikayo liyakhuphuka, lifinyelele ngaphezu kuka-2250°C. I-bauxite, ehlanganiswe namafayili ensimbi kanye ne-coke, iyawa futhi inyibilike emalangabini anamandla, ihlanze futhi isuse ukungcola, ekugcineni yakhe amabhlogo aminyene ansundu e-corundum. Ukukhethwa kohlobo lwesithando somlilo nakho kubamba okwayo: isithando somlilo esitshekisayo sinikeza uketshezi oluhle kakhulu nokuhlanzeka okuphezulu, okufanelekile emikhiqizweni emihle; isithando somlilo esingaguquki sinikeza okukhiphayo okuphezulu kanye nezindleko eziphansi. Abakhiqizi bavame ukukhetha ngokuya ngesidingo.
I-brown corundumamabhulokhi amasha esithandweni somlilo asengama “rough,” kude nokuba yimpushana ecolekileyo. Okulandelayo, i-crusher ithatha indawo: i-crusher enamazinyo amabili yokuchoboza amaholo, ihlephula inqwaba, kuyilapho i-crusher enethonya eqondile yenza ukuchotshozwa okuhle, ihlephula izinhlayiya zibe izingcezu ezinosayizi wamamilimitha. Kodwa akugcini lapho—ukuhlukaniswa kazibuthe nokususwa kwensimbi kubalulekile ngekhwalithi. Uma ivuliwe, isihlukanisi esizibuthe esinezinga eliphezulu singasusa ngokuphelele noma yikuphi ukugcwaliswa kwensimbi okusele kokubalulekile. Izihlukanisi ezinozibuthe ezinamandla aphezulu ezisetshenziswa izinkampani ezifana ne-Henan Ruishi zinganciphisa i-Fe₂O₃ zibe ngaphansi kuka-0.15%, zibeka isisekelo sokukhetha okulandelayo.
Ithangi lokuqoqa libuye libe nezimfihlo. Isixazululo se-15% -25% se-hydrochloric acid sisetshenziswa amahora angama-2-4. Ihlanganiswe ne-Zhenyu Grinding enelungelo lobunikazi “idivayisi yokuhlanza i-push-pull,” impushana iyanyakaziswa futhi igezwe, kuncibilike ukungcola okufana ne-silicon ne-calcium, kuthuthukiswe ukuhlanzeka kwempushana ecolekileyo. Isinyathelo sokugcina sokuhlola sifana “nokusalungiswa”: izikrini ezidlidlizayo zihlinzeka ngokuhlolwa okuqhubekayo, zihlukanisa izinhlayiya ezinhle kusukela kokumahhadla kuya kokuhle. Idivayisi yokuhlola enelungelo lobunikazi ye-Chongqing Saite Corundum ihlanganisa izendlalelo ezintathu zezikrini kanye nesikrini esinengxenye enguhhafu, iqinisekisa ukusatshalaliswa kosayizi wezinhlayiyana ngokunembe njengokungathi kulinganiswa ngerula. Impushana ehlungiwe ecwebile ibe isibhalwa njengoba kudingeka—200#-0 kanye no-325#-0 yizici ezijwayelekile. Inhlayiya ngayinye ifana njengesihlabathi, impumelelo yangempela.
2. Ukuhlola Okuhle: I-Lifeline yekhwalithi ye-Micropowder
Isetshenziswa kuphi i-brown corundum micropowder? Kusukela ekupholisheni ingilazi yocingo oluphathwayo kuya kumalayini omshini wokugaya insimbi, ngisho nokuwohloka kokusebenza okuncane kungaholela entukuthelweni yamakhasimende. Ngakho-ke, ukulawulwa kwekhwalithi kuwumthombo oqhubekayo wokungezwani embonini. Okokuqala, cabangela ukwakheka kwamakhemikhali—Okuqukethwe kwe-Al₂O₃ kufanele kube ≥95% (imikhiqizo ephezulu idinga ≥97%), i-TiO₂ ≤3.5%, ne-SiO₂ ne-Fe₂O₃ kumele igcinwe ngaphakathi kwe-1% kanye ne-0.2% ngokulandelanayo. Ochwepheshe baselabhorethri baqapha i-spectrometer nsuku zonke; ngisho nokushintshashintsha okuncane kwedatha kungaholela ekusebenzeni kabusha kweqoqo lonke.
Ukuhlolwa kwendawo ebonakalayo kunzima ngokulinganayo:
Ukuqina kwe-Mohs kufanele kufinyelele ku-9.0. Isampula liklwejwa kupuleti eliyireferensi; noma yiluphi uphawu lokuthamba lubhekwa njengesehluleki.
Ukuminyana kwangempela kukhawulelwe ku-3.85-3.9 g/cm³. Ukuchezuka kubonisa inkinga ngesakhiwo sekristalu.
Ukuhlolwa kwe-refractory kufuna nakakhulu-ukuqhekeka kanye nempushana ngemva kokuphonswa esithandweni somlilo esingu-1900 ° C amahora amabili? Iqoqo lonke lilahliwe!
Ukufana kosayizi wezinhlayiya kubalulekile emiphumeleni yokupholisha. Umhloli wekhwalithi wendlala isipuni sempushana ngaphansi kokuhlaziya usayizi wezinhlayiyana ze-laser. Noma yikuphi ukuchezuka enanini le-D50 elidlula u-1% kuthathwa njengokuhluleka. Phela, usayizi wezinhlayiyana ongalingani uzoholela ekuklwebheni noma ama-patches endaweni yensimbi ephucuziwe, okuholela ezikhalweni ezivela kumakhasimende.
I-GB/T 2478-2022 ejwayelekile kazwelonke, evuselelwe ngo-2022, isiphenduke i-ironclad yemboni. Lo mbhalo owugqinsi wobuchwepheshe ulawula yonke into kusukela ekwakhekeni kwamakhemikhali kanye nesakhiwo sekristalu kuya ekupakishweni nasekugcinweni kwakhoi-brown corundum. Isibonelo, idinga ukuthi i-α-Al₂O₃ kumele ibonise ifomu elijwayelekile lekristalu elingunxantathu. Uyabona i-crystallization engavamile ngaphansi kwesibonakhulu? Uxolo, umkhiqizo uzoboshwa! Abakhiqizi manje sekufanele babhalise ngisho namazinga okushisa eshede kanye nomswakama—ngenxa yokwesaba ukuthi ama-micropowder azoswakama futhi anqwabelene, kulimaze isithunzi sawo.
3. Ukuguqula Imfucuza Ibe Igugu: Ubuchwepheshe Bokugaywa kabusha Kwephula Inkinga Yensiza
Imboni ye-corundum sekuyisikhathi eside ihlupheka ngenxa yokuqoqwa kwezinto ezihuquza imfucuza namasondo okugaya, angagcini nje ngokuthatha indawo kodwa futhi angcolisa imvelo. Nokho, eminyakeni emibili edlule, ubuchwepheshe be-“corundum obugaywe kabusha” buvele, bunikeza udoti indlela entsha yokuphila. Ilungelo lobunikazi elisha e-Yingkou, eSifundazweni Sase-Liaoning, selithathe isinyathelo sokuphinda sigaywe kabusha: okokuqala, imikhiqizo ye-corundum edoti inikezwa "ukugeza" ukuze kukhishwe ukungcola, okulandelwa ukuchotshozwa nokuhlukaniswa kazibuthe, futhi ekugcineni, ukucolwa okujulile nge-hydrochloric acid. Le nqubo inyusa ukususwa kokungcola ngo-40%, kuletha ukusebenza kwezinto ezigaywe kabusha eduze nalokho kwe-micropowder emsulwa.
Ukusetshenziswa kwezinto ezigaywe kabusha nakho kuyakhula. Amafekthri aphikisayo ayakuthanda ukuyisebenzisela ubumba lwe-taphole-kufanele ixutshwe ezintweni ezisakazwayo noma kunjalo, futhi izinto ezigaywe kabusha zinikeza ukuphumelela kwezindleko okumangalisayo. Okungcono nakakhulu, inqubo yokubuyisela kabusha iyanciphai-brown corundumkubiza ngo-15% -20%, okwenza abaphathi bajabule ngendlela emangalisayo. Nokho, omakadebona embonini bayaxwayisa: “Ukupholishwa okunembayo kudinga izinto ezisetshenziswayo zebanga lokuqala. Uma ngisho nokungcola okuncane kuxutshwa ezintweni ezigaywe kabusha, indawo eyizibuko izophawulwa ngaso leso sikhathi!”
4. Isiphetho: I-Micropowder, Incane Njengoba Injalo, Ithwala Isisindo Semboni
Kusukela emalangabini avuthayo eziko zikagesi ze-arc kuya ekudumeni kwezihlukanisi kazibuthe, kusukela ekucushweni kwamathangi okucosha kuya emigqeni yokuskena yabahlaziyi besayizi yezinhlayiyana ze-laser—ukuzalwa kwe-brown corundum micropowder kuwumlando omncane wemboni yesimanje. Amalungelo obunikazi amasha, amazinga amasha kazwelonke, kanye nobuchwepheshe obugaywe kabusha buyaqhubeka nokukhulisa uphahla lwemboni. Isidingo sezimboni ezisezansi nomfula sokunemba okucishe kudlulele kokwelashwa siyaqhubeka nokuqhubekisela phambili ikhwalithi ye-micropowder. Emgqeni wokuhlanganisa, izikhwama zempushana ensundu ziyavalwa bese zilayishwa emalolini, aya ezimbonini ezweni lonke. Angase angaculwa, kodwa asekela amandla ayisisekelo e-Made in China, ngaphansi kopholishi olukha phezulu.
