Ukusebenza Kakhulu Kwe-White Corundum Micropowder Ekupholiseni Amatshe
Uma sikhuluma iqiniso, uma kukhulunywa “ngokupholisha amatshe,” umcabango wokuqala wabantu abaningi ungase ube imishini emikhulu, amafektri anomsindo, kanye namadiski okugaya ezandleni zabapholishi abanolwazi. Kodwa uma uyiqonda ngempela imboni, uzothola ukuthi ngokuvamile yizimpuphu ezincane ezingabonakali ezinquma ngempela imiphumela yokugcina. Isibonelo,i-white corundum micropowderEsixoxa ngakho namuhla ukuthi “ingcweti yokupholisha” ifihleke ngemuva kwezigcawu. Ngesikhathi ngiqala ukusebenza kulo mkhakha, ngangididekile futhi: Akukhona yini ukupholisha itshe nje? Noma iyiphi “impuphu” ayinandaba. Kodwa ngemva kokubona okwengeziwe, ngaqaphela ukuthi ukukhetha i-micropowder efanele kungenza umehluko omkhulu emiphumeleni.
1. Iyini i-white corundum micropowder? Kungani ifaneleka ukupholisha?
I-corundum emhlophe, uma siyibeka kalula, iwubumsulwa obukhulu obenziwe ngumuntui-aluminium oxide (Al₂O₃). Kunzima kune-corundum yemvelo, enobunzima be-Mohs obungu-9.0, okwesibili emva kwedayimane ne-silicon carbide. Njengoba igama lisikisela, elithi “micropowder” libhekisela ezintweni ezichotshoziwe futhi zahlungwa zaba yi-micron-level fine powder. Ungase ubuze: “Le nto ngeke yini iklwebhe itshe?” Lokhu kusiletha ezinzuzweni zayo: ubulukhuni obuphezulu kodwa ukuqina okuhle kakhulu: izinhlayiya ze-corundum ezimhlophe ziyamelana nokuphuka, zigcina amandla okusika afanayo ngesikhathi sokupholisha; ukuzinza kwamakhemikhali: azihlangani namaminerali etsheni, okubangela ukubola noma ukugqwala; kanye nosayizi wezinhlayiya olawuleka kakhulu: zinikeza isevisi ephelele kusukela ekugayeni okuqinile kuya ekupholiseni okuhle, okwenza zifaneleke kakhulu ezinqubweni zokupholisha zezigaba eziningi. Lezi zici ziyenza ifaneleke kakhulu ekucubunguleni amatshe okuhlobisa avamile njengemabula, i-granite, kanye netshe lokwenziwa.
II. Yini ngempela eyenza kube “okusebenza kahle” kangaka ekupholisheni kwangempela?
Abantu abaningi bacabanga ukuthi ukupholisha kumane nje kumayelana nokuletha isiphetho esikhanyayo ebusweni betshe, kodwa akunjalo. Inqubo enhle yokupholisha kumele isuse ngokushesha imihuzuko ngenkathi ithuthukisa kancane kancane ukucwebezela, kuyilapho futhi igwema ukupholisha ngokweqile noma ukulimaza okusanhlamvu.
1. Ukupholisha okuqinile, okuphakathi nendawo, nokucolisisiwe kahle, kuqediwe kahle
Isibonelo, lapho usebenza ngezitezi zemabula:
Ukupholisha okuqinile (80#-200#): Sebenzisa umshini oqinilei-white corundum powder(njenge-W40-W20) ukuze kusheshiswe ukushelela indawo futhi kususwe imihuzuko ejulile;
Ukupholisha okuphakathi nendawo (400#-800#): Shintshela ku-powder ecolekile (njenge-W14-W7) ukuze upholise kokuqala;
Ukupholisha kahle (1500#-3000#): Ngisho nophudingi olune-W3.5 noma ngaphansi lungasetshenziswa ukufeza ukuqeda okufana nesibuko.
Uzothola ukuthi izimpushana zezinto ezifanayo, ngobukhulu bezinhlayiya obuhlukahlukene, zingasetshenziswa kuyo yonke inqubo yokupholisha, kususwe isidingo sokushintsha izinto njalo—ukonga isikhathi, umzamo, namaphutha.
2. Ukunamathela okuqinile kanye nokupholisha okusheshayo
Uma kuqhathaniswa nezinto zendabuko ezifana nomhlaba we-diatomaceous kanye ne-cerium oxide, i-white corundum powder, enezinhlayiya zayo ezicijile (esikhundleni se-spherical), imuncwa kalula ebusweni betshe, okuholela ekusebenzeni kahle kokusika okuphezulu. Senze ukuqhathanisa: ukupholisha ucezu olufanayo lwe-granite nge-white corundum micropowder kungafeza ukukhanya okufanayo ngesikhathi esingaphansi kwe-1/3 kunokupholisha ngezinto ezivamile.
3. Akukhethi izinto zamatshe, kunezinto eziningi ezisebenziseka kalula
I-corundum emhlophecishe iyinto yonke, kungakhathaliseki ukuthi imabula ene-asidi eningi noma i-granite enokuqukethwe okuphezulu kwe-silica. Lokhu kuyiqiniso ikakhulukazi ngamatshe okwenziwa ahlanganisiwe (njenge-quartz), aqukethe kokubili i-resin kanye nezinto zamaminerali. Ama-abrasives amaningi endabuko angabangela kalula ukuthi abe matte noma angabi nsundu, kuyilapho i-corundum emhlophe ihlala inikeza ubukhali.
4. Isikhathi eside sokuphila kanye nezindleko eziphansi eziphelele
Nakuba i-white corundum micropowder ingase ibize kancane ngeyunithi ngayinye kunezinye izinto zendabuko, ayigugi, imelana nokubuthaka, futhi inikeza izinga eliphezulu lokusetshenziswa kabusha. Ngokuvamile, iqoqo lezinto lingamboza indawo engaphezulu engu-20%-30%, okwenza kube ngcono kakhulu ngokuhamba kwesikhathi.
Ⅲ. Zikhona yini izibonelo zangempela? Ingabe kuyasebenza ngempela?
Ake ngikunike isibonelo sami: Ngonyaka odlule, kwavuselelwa indawo yokwamukela izivakashi ehhotela. Iphansi lemabula eli-beige lalimbozwe imihuzuko yeminyaka eminingi yokusetshenziswa futhi lalinokukhanya okungaphansi kuka-30. Ithimba lokwakha ekuqaleni lasebenzisa i-powder evamile yokupholisha, kodwa ngemva kokukhanya okuthathu, imiphumela yayinganelisi. Base beshintshela ku-paste yokupholisha esekelwe ku-white corundum micropowder. Ngemva kokukhanya okubili nje, bathola ukukhanya okungaphezu kwama-degree angu-75. Ukukhanya kokugcina lapho kulethwa kwakuseduze no-85. Iklayenti lavuselela inkontileka ngokushesha. Ingcweti eyinhloko yasho okuthile okusuka enhliziyweni: “Le nto ifana nokuthola isikhali esisha emdlalweni—ibulala izilo ngokushesha futhi ayikubizi ngalutho impilo.”
IV. Imikhuba Yentuthuko Yesikhathi Esizayo? Ingabe Izothathelwa Indawo?
Njengamanje, i-white corundum powder igcina isikhundla esiqinile ekupholisheni amatshe, kodwa futhi iyashintsha:
Usayizi wezinhlayiya ezincane nezincane: Impuphu ye-corundum emhlophe ye-Nano-grade (isb., i-W1.0 nangaphansi) isiqalile ukusetshenziswa ekupholisheni kwe-ultra-mirror, ikakhulukazi ekuhlobiseni okuphezulu nasekucubungulweni kwamatshe obuciko;
Ukusetshenziswa okuhlanganisiwe: Isibonelo, uma kuxutshwe ne-cerium oxide kanye ne-diamond powder, kufinyelela amandla okusika alinganayo kanye nokucwebezela, okufanelekela izinto ezikhethekile zamatshe;
Ukuvikelwa kwemvelo okuthuthukisiwe kanye nokuphepha: Isizukulwane esisha sama-slurry okupholisha asekelwe emanzini kancane kancane sithatha indawo yama-dry powder amadala, sinciphisa ukungcola kothuli futhi siwenze afaneleke kakhulu ekusetshenzisweni kwemishini okuzenzakalelayo;
Isiphetho: Izinto Ezincane, Umthelela Omkhulu
Ngokuvamile, sigxila kokusobala—njengohlobo lomshini wokupholisha noma idumela leqembu lokwakha—kodwa singanaki imininingwane ethinta imiphumela ngempela.Impuphu ye-corundum emhlophe kuyinto “ephansi, kodwa ebalulekile”. Uma uvuselela indlu yakho noma usebenza embonini yokunakekelwa kwamatshe, ngesikhathi esizayo lapho uhileleka enkambisweni yokupholisha, ungase ubuze omunye umbuzo: “Luhlobo luni lwempuphu encane esiyisebenzisayo?” Umphumela wokugcina ungase uhluke ngokuphelele ngenxa yalo mbuzo.
