Ucwaningo Ngethonya Le-Brown Fused Alumina Micropowder Ebunzimeni Bokujiya Komphezulu Wezinto Ezibonakalayo
Emsebenzini wethu, ikakhulukazi ekuphathweni kwendawo noma ekucutshungulweni kwezinto, sibhekana nesibonakaliso "sobulukhuni" cishe nsuku zonke. Kufana "nophawu lweminwe" lwento, okunquma ngqo ukuthi ingubo elandelayo inganamathela yini, ukuthi izingxenye ezingagugi kangakanani, ngisho nomphumela wokuvala wenhlangano. Namuhla, masingakhulumi ngalezo zinkolelo-mbono zezinga eliphezulu, kodwa hlala phansi sixoxe njengozakwethu ngomngane wethu omdala esimaziyo kakhulu - i-alumina micropowder ensundu exutshwe - nokuthi "iphatha" kanjani ubulukhuni bendawo yezinto.
I. Okokuqala, ake siqonde: Iyini ngempela i-alumina micropowder ensundu exutshwe?
I-alumina ensundu ehlanganisiweKalula nje, yilokho “esikucwenga” sisebenzisa izinto ezifana ne-alumina ne-coke esithandweni sikagesi se-arc. Ngenxa yokuthi iqukethe i-titanium kanye ne-iron oxides, inombala onsundu, yingakho ibizwa kanjalo. Inobulukhuni obukhulu, ukuqina okuhle, futhi ingabizi, okwenza kube “yisithako esiyinhloko” ekuqhumeni nasekugayeni isihlabathi.
Futhi igama elithi “micropowder” liyisihluthulelo. Libhekisela kumpuphu ocolekile kakhulu otholakala ngokuchoboza nokuhlikihla i-alumina ensundu exutshwe ngenqubo ekhethekile, enobukhulu bezinhlayiya obuvame ukusuka emakhulwini amaningana kuya ezinkulungwaneni eziningana zama-meshes. Ungayithathi kalula le mpuphu; ayiseyona “ummese wokugawula izinkuni” onzima, kodwa “ummese wokuqopha” onembile. Ukuvela kwayo kuvumele i-alumina ensundu exutshwe ukuba isuke emisebenzini enzima njengokususa isikali se-oxide esijiyile kusuka ekubunjweni iye ensimini yomshini wokulungisa ngokunemba, lapho kudingeka khona ikhwalithi ephezulu kakhulu ebusweni.
II. “Iqopha” Kanjani Ubuso? – Umhlaba Onamandla Osebenzisa Ama-Microscopic
Abantu abaningi bacabanga ukuthi ukuqhuma kwesihlabathi kuwukushaya nje ubuso ngesihlabathi, futhi uma ushaya kanzima, kuba nzima nakakhulu. Lokho kuyiqiniso kancane, kodwa kulabo kithi abafunda ngama-micro-powders, enye ingxenye iyona eyinhloko. Ithonya le-brown fused alumina micro-powder ekuqineni kobuso kuyinqubo eyinkimbinkimbi enamandla, engiyifingqa ngemiphumela emithathu eyinhloko:
Umphumela “Wokubhoboza” (Ukusika Okukhulu): Lokhu kunembile kakhulu. Izinhlayiya ezincane zempuphu ezindizayo ngesivinini esikhulu, njengezingodo ezincane ezingenakubalwa kanye nezinsika, zithinta ubuso bezinto ezibonakalayo. Izinhlayiya eziqinile “zizoluma” ngqo izinto ezibonakalayo, zakhe imigodi emincane. Lesi sigaba yisona esibangela ukuba ubuso bube lukhuni ngokushesha. Cabanga ngobuso obubushelelezi obukhishwa ngemigodi emincane engenakubalwa; umehluko phakathi kweziqongo nezigodi uyanda kakhulu, ngokwemvelo uphakamisa amanani obulukhuni (isib. Ra, Rz).
Umphumela “wokulima” (ukuguqulwa kwepulasitiki): Lokhu kuyathakazelisa. Uma izinhlayiya zingathinti ubuso ngqo, kodwa kunalokho “zibuklwebha” nge-engeli, zingase zingasiki ngqo izinto. Esikhundleni salokho, njengokulima, “zicindezela” izinto ezingaphezulu ezinhlangothini, zakha “umsele” ophakanyisiwe. Le nqubo ayisusi ngqo izinto, kodwa ngokuguqulwa kwepulasitiki, ishintsha isimo sobuso, yandisa umehluko phakathi kweziqongo nezigodi.
Imiphumela “Yokucinana” kanye “neyokukhathala”: Ngaphansi komthelela oqhubekayo wezinhlayiya ezincane, ubuso bezinto budlula enkambisweni “yokucwengisisa” ngemiphumela ephindaphindwayo. Imiphumela yokuqala ingase ikhulule ubuso, kodwa imiphumela eqhubekayo empeleni “iyacinana” ungqimba lobuso, yakha ungqimba oluqinile noluqinile. Ngesikhathi esifanayo, imiphumela ephindaphindwayo ibangela ukukhathala esakhiweni sobuso bezinto, okwenza kube lula ukuthi izinhlayiya ezilandelayo zisuswe.
Njengoba ubona, ngisho nenqubo elula yokuqhumisa isihlabathi ihilela imiphumela emithathu ngesikhathi esisodwa futhi isebenzisana emhlabeni omncane: “ukumba,” “ukulima,” kanye “nokuxova.”
III. Izici Ezintathu Eziyinhloko Ezithinta Imiphumela: Usayizi Wezinhlayiya, Ingcindezi, kanye Ne-Engela
Manje njengoba sesiyiqonda le simiso, "siyiyala" kanjanii-alumina micropowder ensundu ehlanganisiweukufeza ukurhabaxa kobuso obufunwayo ekusebenzeni kwangempela? Kuncike kakhulu kulezi zici ezintathu ezibalulekile:
Isici Sokuqala: Usayizi Wezinhlayiya (Impuphu kufanele ibe nkulu kangakanani?)
Lena yipharamitha ebaluleke kakhulu. Kalula nje, ngaphansi kwezimo ezifanayo, lapho izinhlayiya zikhula kakhulu, inani lobukhulu bomphezulu liba likhulu. Ukusebenzisa i-80-mesh coarse powder kuzokhiqiza ubuso obuqinile kakhulu ngemivimbo embalwa; kodwa uma usebenzisa i-W40 noma ngisho ne-micropowder encane, ubuso obuvelayo buzoba bushelelezi kakhulu futhi bube nomuzwa omuhle. Lokhu kufana nokusika ukhuni nge-sandpaper eqinile uma kuqhathaniswa ne-sandpaper encane—imiphumela ihluke kakhulu. Ngakho-ke, ukuthola ubukhulu bomphezulu obuphansi, ukukhetha i-micropowder encane kuyisinyathelo sokuqala.
Isici sesibili esiyisihluthulelo: Ukucindezela kwesifutho (Amandla angakanani?)
Ukucindezela amandla anikezwa izinhlayiya. Uma ukucindezela kukhulu, izinhlayiya zindiza ngokushesha, amandla e-kinetic aba nawo amaningi, futhi umphumela "wokumba" kanye "nokulima" unamandla kakhulu, okuholela ekuqineni okukhulu ngokwemvelo. Kodwa-ke, kukhona ugibe: ukucindezela okuphezulu akuhlali kungcono. Ukucindezela ngokweqile kungaholela ekusikeni ngokweqile, kulimaze ngisho nokunemba kobukhulu bomsebenzi, noma ngisho nokuphula izinto eziqhekeka kalula. Okuhlangenwe nakho kwethu ukuthi, ngenkathi sihlangabezana nezidingo zokuhlanza kanye nokuqineka, kungcono ukusebenzisa ukucindezela okuphansi kakhulu—"sebenzisa insimbi engcono kakhulu lapho ibalulekile."
Isici sesithathu esiyisihluthulelo: I-engeli yokufutha (Ivela ngakuphi?)
Abantu abaningi bayayishaya indiva le pharamitha. Ucwaningo lubonisa ukuthi uma i-engeli yokufafaza iphakathi kuka-70° no-90° (cishe iqonde), ukwanda kobulukhuni kubaluleke kakhulu ngoba umphumela "wokumba" uyabusa. Lapho i-engeli iba ncane (isb., 30°-45°), umphumela "wokulima" uba sobala kakhulu, okuholela kuphrofayili ehlukile yobulukhuni. Uma sifuna ukuhlanza indawo kodwa singafuni ukuthi ibe nzima kakhulu, ngezinye izikhathi sisebenzisa i-engeli encane ukuze sifinyelele ibhalansi phakathi kokuhlanza nobulukhuni.
IV. “Izimfihlo” kanye Nokuzindla Ekusetshenzisweni Okungokoqobo
Ithiyori iyodwa ayanele; kunezimfihlo eziningi ezitholakala emsebenzini wangempela.
Isibonelo, "izinga lokushisa" lomsebenzi (izakhiwo ezingokwemvelo zezinto) kubalulekile. Ukusebenzisa amapharamitha afanayo ukushaja insimbi ecinyiwe enobulukhuni obukhulu uma kuqhathaniswa ne-aluminium ethambile kuzoveza imiphumela ehluke ngokuphelele. Izinto ezithambile zithambekele kakhulu ekuguqukeni kwepulasitiki, zikhiqiza "imisele" ejulile nebanzi futhi ivaleke kalula; izinto eziqinile zivame ukuqhekeka kalula, zakhe imigodi eminingi.
Esinye isibonelo "isikhathi sokuphila" kwe-micro-powder.Impuphu encane ye-alumina ensundu ehlanganisiweizoguga futhi iphuke ngokuhamba kwesikhathi. Iqoqo elisha lempuphu linosayizi wezinhlayiya ezifanayo, imiphetho ebukhali, kanye namandla okusika aqinile, okukhiqiza ubulukhuni obufanayo nobukhulu. Kodwa-ke, impuphu esetshenzisiwe, enemiphetho eyindilinga kanye nosayizi wezinhlayiya ezincane, iba “ndala futhi igugile,” ngamandla okusika ancishisiwe, okungenzeka ikhiqize ubulukhuni obuncane nobufanayo, obufanele ukuqedwa “kwe-satin” okuhlala njalo. Konke kuncike ezidingweni zakho zenqubo.
Ngakho-ke, ukufunda umphumela wei-alumina encane ehlanganisiwe ensunduUkungalungi kobuso akuyona nje indaba yokubheka izinto bese usebenza ngokufanele. Kuwubuciko bokulawula okunembile ezweni elincane kakhulu. Sidinga ukuba njengodokotela wezokwelapha wendabuko waseShayina onolwazi, siqonde ngobuchule izakhiwo nezindlela “zamakhambi ezokwelapha” njenge-“izinhlayiya, ingcindezi, kanye ne-engeli,” bese sihlanganisa lokhu “nokwakheka” kwezinto zokusebenza, ukuze sinikeze “ikhambi” elisebenza kahle kakhulu futhi sifinyelele lokho kungalungi kobuso okuphelele.
