Izinzuzo Eziyingqayizivele Ze-White Corundum Ekupholisheni Ubucwebe
Izingcweti ezingochwepheshe embonini yobucwebe zinesisho esithi: “Izingxenye ezintathu zezinto zokwakha, izingxenye eziyisikhombisa zobungcweti.” Itshe eliyigugu eliyindilinga elisezingeni eliphezulu kanye neqoqo lezinsimbi eziyigugu eziklanywe ngobuhlakani ziguqulwa zibe umsebenzi wobuciko omangalisayo ebhokisini lokubonisa, futhi izinyathelo zokugcina zokupholisha ziyi-“think yokuqeda” yangempela. Lokhu “kuthinta kokuqeda” kudinga ikhono elikhulu. Amathuluzi asetshenziswayo kanye nenani lamandla asetshenziswayo konke kuncike ekhonweni lomdwebi. Futhi uma kukhulunywa ngezinto zokupholisha, kukhona imfihlo eqashwe kakhulu embonini—i-corundum emhlophe. Ngokungafani ne-diamond powder, ekhangayo futhi eyigugu, noma ezinye izinto zamakhemikhali, ezifihliwe yimfihlakalo, kufana “nomngane omdala” ozinzile nothembekile, othembele emakhono akhe aqinile kanye nokunaka ngokucophelela imininingwane ukuze abambe indawo yawo ezweni elifihliwe lokupholisha ubucwebe.
Le nto, enegama layo elizwakala njengelezimboni, elithi “white corundum,” ingase ibonakale njengento esetshenziswa efektri ukusebenza ngamabhulokhi amakhulu ensimbi. Kodwa akunjalo nhlobo. Uma uyihlikihla phakathi kweminwe yakho, ukupholisha okusezingeni eliphezului-white corundum micro-powder Icwebezela njengofulawa omuhle kakhulu, inokukhanya okupholile, okufana ne-porcelain. Uhlobo lwayo lwangempela yikristalu ye-alumina emsulwa kakhulu, etholakala ngokuncibilika kwezinga lokushisa eliphezulu, ukuchotshozwa ngokucophelela, kanye nokuhlelwa. Inobulukhuni obuphezulu, ilandela idayimane ne-silicon carbide kuphela, kodwa isimo sayo sithambile kakhulu futhi siyalawuleka kunalawo “mathambo amabili aqinile.” Yilesi sici “esinzima kodwa esingesiqinile” esenza kube “okuphelele” kokuphatha izinto zokuhlobisa ezahlukahlukene ezibucayi.
Kungani kubhekwa “njengokuphelele”? Ake sikuchaze.
Okokuqala, “iyaqaphela” izinto zokwakha, noma kunalokho, “iyaqaphela izinto zokwakha.” Embonini yobucwebe, izinto zokwakha zihlukahlukene kakhulu: izinto zokwakha ezinobulukhuni obuphezulu njenge-sapphire ne-ruby, izinto zokwakha ezinobulukhuni obuphakathi njenge-jadeite ne-nephrite, kanye nezinhlobo ezahlukene zegolide le-karat, i-platinum, nesiliva. Awukwazi ukusebenzisa “umbusi” owodwa ukukala konke. Inzuzo ye-alumina emhlophe ehlanganisiwe itholakala ekhonweni layo lokunakekela izinto zokwakha ezahlukahlukene ngokulungisa ubuncane bezinhlayiya zayo (ezaziwa ngokuthi “i-mesh”). Izinhlayiya ezinkulu (isb., i-mesh engu-600 kuya ku-1000) zisetshenziselwa “ukupholisha” kokuqala, zisusa ngokushesha amamaki amakhulu kanye nemiphetho ebukhali eshiywe ngemva kokusika—inqubo ebizwa ngokuthi “ukushelela.” Ezigabeni zakamuva, kusetshenziswa ngisho nezimpuphu ezincane, njenge-mesh engu-2000, 3000, noma ngisho namashumi ezinkulungwane. Kuleli qophelo, umsebenzi wayo oyinhloko awusasikhi, kodwa kunalokho, ngokungqubuzana kwezinhlayiya ezincane ezingenakubalwa, kancane kancane "ikhipha" ngisho nemihuzuko emincane ebusweni, okuholela ekukhanyeni okufiphele (okungacwebezeli) noma umphumela ofana nesibuko. I-alumina emhlophe ehlanganisiwe ingaphatha lonke ushintsho kusukela "olunzima" kuya "olucwengisisiwe," ngokushintsha kwenqubo okubushelelezi, izinguquko ezincane zezinto ezibonakalayo, kanye nokulula kokusetshenziswa kwabachwepheshile abanolwazi.
Okwesibili, “kuhlanzekile.” Lokhu kubaluleke kakhulu. Yini eyesabekayo kakhulu ekupholisheni ubucwebe? Ukungcola kanye “nokuphuma kombala.” Ezinye izinto zokupholisha zinombala omnyama noma ziqukethe ukungcola. Ngesikhathi sokupholisha ngesivinini esikhulu, izinga lokushisa eliphezulu lingagcina umbala noma ukungcola kalula emifantwini emincane yetshe eliyigugu noma ukuthungwa kwensimbi, konakalise umsebenzi—inqubo eyaziwa embonini ngokuthi “ukudla ukungcola.”I-alumina emhlophe ehlanganisiweNgakolunye uhlangothi, inombala omhlophe futhi izinzile kakhulu ngamakhemikhali, ayishintshi kalula ngisho nasemazingeni okushisa aphezulu. Uma isetshenziselwa ukupholisha, ikakhulukazi ekupholiseni izinsimbi ezimhlophe ngokukhazimula okuphezulu (iplatinum, igolide elimhlophe, isiliva) noma amatshe ayigugu angenambala noma anombala okhanyayo (amadayimane, ikristalu, ama-sapphire anombala okhanyayo), ikhiqiza ukukhanya okumhlophe okukhanyayo “okubandayo,” kwangempela ngaphandle kokwengeza ukungcola, okugcina umbala oyisisekelo omsulwa kanye nomlilo wezinto. Lokhu “kumsulwa” kuyindinganiso yegolide embonini yobucwebe.
Ngaphezu kwalokho, “kuthambile futhi kuyalawuleka.” Ukupholisha akukhona ngamandla amakhulu, kodwa kumayelana nekhono; kumayelana nokusebenzisa ingcindezi ngempumelelo ngaphandle kokulimaza impahla. Izinhlayiya zei-alumina emhlophe ehlanganisiwe, ikakhulukazi i-powder ecolekileyo ene-mesh ephezulu, inezimo ezijwayelekile (nakuba iphukile, ilinganisiwe) kanye nemiphetho efanayo. Uma isetshenziswa ne-polish paste efanele (uwoyela) esondweni lokupholisha noma endwangu, yakha "ungqimba oluncane lokusika" olufanayo noluzinzile. Ingcindezi esetshenziswa yingcweti enekhono ingadluliselwa ngokulinganayo nangokuhamba kancane ebusweni bobucwebe ngale ndlela. Ukukhanya okuphumelayo "kubukhoma," ukukhanya okuqhubekayo, okukhazimulayo okukhanya ngaphakathi, kunokuba kube ukukhanya okungaphezulu, okwenziwayo. Ikakhulukazi lapho kuphathwa ubucwebe begolide obugobile, obuqoshwe kahle, noma obunombhalo omuhle, isimo esibucayi se-agate emhlophe ehlanganisiwe sibonisa ikhono ngempela. Ingena emininingwaneni emincane kakhulu, iletha ukukhanya kuwo wonke amakhona, kunokuba ilungise imininingwane cishe.
Yiqiniso, ngisho nezinto ezingcono kakhulu zincike kumsebenzisi. Izingcweti ezinekhono ziphatha i-agate emhlophe ehlanganisiwe njengomngane wakudala. Izimpushana ezahlukene zegrit zixutshwa namafutha ahlukene, futhi ukuhambisana kucatshangelwa ngokucophelela; izinto zokwakha kanye nobunzima besondo lokupholisha, isivinini sokujikeleza, ingcindezi kanye nokunyakaza kwesandla, kanye nokuzola komenzi ngesikhathi sokupholisha konke kuthinta ukukhanya kokugcina. Bavame ukuthi, “I-agate emhlophe ehlanganisiwe ayikhulumi, kodwa ukukhanya kwayo kukhuluma lukhulu.” Yiphathe ngokucophelela, futhi “izokhuluma” ukukhanya kwayo okukhazimulayo, okusobala, nokuhlala njalo ebucwebeni.
Ngakho-ke, uma ukhangwa ukukhanya okumangalisayo kwengcezu yobucwebe ebhokisini lokubonisa, lokho kukhanya kungenzeka ukuthi kudlule izinqubo eziningi, kusukela esihlabathini esiqinile kuya ku-powder ecolekile. Futhi esinyathelweni sokugcina sokuyinika umbono ojulile nokhanyayo, i-agate emhlophe ehlanganisiwe—le nto “emnene kodwa eqinile”—ingadlala indima ethule kodwa ebalulekile. Ayinawo ubukhali obukhulu be-powder yedayimane, kodwa inomqondo omkhulu wokupha nokubandakanya; ayilandeli ukukhanya okusheshayo, kodwa idlula ekuvuseni kancane kancane ukukhanya okungokwemvelo kwento ngokwayo.
Kufana nomenzi wezinto zobuciko oqonda ngokujulile ubuciko “bokububula kancane,” esebenzisa isineke nobumsulwa ukupholisha ubucwebe ngabunye ukuze embule ungqimba lwawo oluyingqayizivele, lokugcina, nolushukumisa kakhulu lokukhanya kwempilo. Lokhu kukhanya akukhazimuli, kodwa kuthinta inhliziyo. Mhlawumbe lokhu ukufudumala kobuciko, okugeleza buthule phakathi kwempuphu ecolekileyo nesondo elijikelezayo.
