I-Green Silicon Carbide Micropowder: I-Powerhouse Yokuthuthukisa Ukusebenza Kwezimbozo Zezimboni
Namuhla, ake sixoxe ngasese ngalokho okwenza le micropowder eluhlaza ye-silicon carbide ibe ekhethekile kangaka.
I. Okokuqala, ake sicacise ukuthi le "green silicon carbide" imayelana nani.
Ukuzwa leli gama okokuqala, kuzwakala “kungokwekhemikhali” futhi kubuchwepheshe obuphezulu. Kodwa empeleni, kufana nomzala we-alumina emhlophe ehlanganisiwe esikhulume ngayo ngaphambili—bobabili bangamalungu omndeni wezinto zokwakha eziqinile kakhulu.
Ukudalwa kwayo kufana nokwenza insimbi: izinto zokusetshenziswa ezifana nesihlabathi se-quartz kanye ne-petroleum coke ziphonswa esithandweni sokumelana nogesi futhi "zicwengisiswe" emazingeni okushisa angaphezu kwama-degree Celsius angu-2000. Ngenxa yokuthi iqukethe izakhi ezithile, icwebezela ibe lo mbala oluhlaza oyingqayizivele, yingakho igama layo libizwa ngokuthi "i-green silicon carbide."
Izimfanelo zayo eziyinhloko zihlukaniswe ngamagama amabili: okuqinile nokubukhali.
Kunzima kangakanani? Esikalini sikaMohs, sifika ku-9.2–9.5! Kusho ukuthini lokho? Sesibili emva kwedayimane (10) futhi sidlula kude izinsimbi ezivamile, ingilazi, kanye nemabula ngokuqina. Ngaphezu kwalokho, izinhlayiya zaso ngokwemvelo zinemiphetho ebukhali namakhona, ngokungafani nezinye izigcwalisi eziyindilinga ezibushelelezi neziyindilinga.
Cabanga ngayo njengezigidigidi zamafayela amancane, aqinile kakhulu “edayimane.” Kithi embonini yokugqoka, ukuyifaka ephepheni kufana nokunikeza ingubo ungqimba olungabonakali “lwezembatho zensimbi zeketanga.”
II. Ikwenza kanjani ngempela ukumbozwa "okunamandla"?
Ukuzisholo nje ukuthi ilukhuni kumane nje kuyinto engenamsebenzi. Inani layo langempela lisekuthuthukiseni ukusebenza kwe-coating—yilapho umlingo wangempela uvela khona.
Okokuqala nokubaluleke kakhulu—okukhethekile kwayo—ukumelana nokuklwebheka nokuklwebheka.
Lokhu kulula ukukuqonda. Cabanga ngesikhumba sakho esimbozwe ngezinhlayiya eziningi eziqinile kakhulu, ezibukhali njenge-razor. Uma okuthile kukuklwebha noma kukugaya, la maphuzu aqinile akha "umugqa wokuqala wokuzivikela." Amandla angaphandle kumele aqale awanqobe ngaphambi kokufinyelela isisekelo se-resin esithambile ngaphansi.
Kufana nokuhamba odakeni oluthambile—isinyathelo ngasinye sishiya umkhondo ojulile. Kodwa endleleni egandayiwe ngamatshe aqinile, ngeke ushiye mkhondo. Ukuhlolwa kwethu kubonisa ukuthi ukugqoka phansi kwe-epoxy okunefomula efanayo kodwa okuhlanganisa inani elifanele le-silicon carbide micropowder eluhlaza kungaphinda kabili noma kathathu isikhathi sabo sokuphila uma kuhlolwa ngomshini wokuhlola ukuklwebheka! Ezindaweni ezifana nama-workshop asefektri, izindawo zokupaka, kanye nezindawo zokugcina impahla ezinkulu, lokhu kusebenza kubaluleke kakhulu.
Inzuzo yesibili ukunamathela okuthuthukisiwe, okuvumela ukuthi isembozo "sibambe" ngokuqinile.
Le nzuzo ingase imangaze abantu bangaphandle. Lezi zinhlayiya ze-micropowder azigcini nje ngokuntanta nje kuphela embozweni—zakha isakhiwo “se-anchor chain” esincane kakhulu. Ngakolunye uhlangothi, izindawo zazo eziqinile zihlangana kahle ne-resin. Ngakolunye uhlangothi, uma zisetshenziswa ezintweni ezingaphansi komhlaba njengensimbi noma ukhonkolo, lezi zinhlayiya eziqinile zingena ezindleleni ezincane kakhulu, zidale amandla anamandla okuxhumanisa ngomshini.
Kalula nje: izembozo ezivamile zifana nokusebenzisa inhlaka ukuze unamathisele iphepha elibushelelezi odongeni. Nokho, izembozo ezine-silicon carbide eluhlaza zifana nokulungisa ubuso bodonga kuqala, bese uzinamathisela ngezikhonkwane ze-hook-and-loop. Izinga lokunamathela alinakuqhathaniswa. Lokhu kubalulekile ekuvimbeleni ukuqhekeka nokuqhekeka kwesembozo.
Inzuzo yesithathu: Ukumelana nokushelela okuthuthukisiwe, okubeka phambili ukuphepha.
Kungakhathaliseki ukuthi yizitezi zasefektri, amadekhi emikhumbi, noma amabhuloho abahamba ngezinyawo, ukumelana nokushelela kubaluleke kakhulu. Izinhlayiya ze-silicon carbide micropowder eziluhlaza zisatshalaliswa ngokulinganayo phezu kobuso obumboziwe, zakha ama-protrusion amancane, aqinile akhulisa kakhulu ubulukhuni bomphezulu futhi athuthukise i-coefficient yokungqubuzana.
Izisebenzi ezigqoke amabhuzu okuphepha zizizwa ziphephile uma zihamba kuwo; abahamba ngezinyawo ngezinsuku zemvula cishe abasheleli. Isiqinisekiso sokuphepha esinikezwa yilokhu asinakuqhathaniswa.
Okwesine, iyindlela eguquguqukayo yokusebenza, enikeza kokubili ukumelana nokushisa kanye nokumelana nokugqwala.
I-silicon carbide eluhlaza ngokwayo inezakhiwo zamakhemikhali ezizinzile kakhulu, imelana nama-acid, ama-alkali, i-oxidation, futhi iphumelela kakhulu ezindaweni ezishisa kakhulu. Ukuyifaka ezimbozweni kudlulisela ngempumelelo lezi "zimfanelo" eziphakeme. Emishinini esezitshalweni zamakhemikhali noma emapayipini okushisa okuphezulu, lokhu kuphakamisa ukuqina kwengubo kuye ezingeni elisha.
III. Ngisho nethuluzi elihle lidinga ikhono: Ubuciko bokusebenzisa
Yiqiniso, ithuluzi elibukhali lisebenza kahle njengomsebenzisi walo—awukwazi ukulisebenzisa nje ngokungacabangi. Kunomqondo omncane ohilelekile.
Okokuqala, ukukhetha usayizi wezinhlayiya ezifanele kuwubuciko ngokwako. Impuphu ye-silicon carbide eluhlaza isukela kumakhulu kuya ezinkulungwaneni ze-mesh. Uma usebenzisa ibanga eliqinile kakhulu—ake sithi, i-mesh eyi-100 noma ngaphezulu—indawo yokumboza izozwakala inzima uma uyithinta, ithinta ubuhle. Ngokuphambene nalokho, ukusebenzisa ibanga eliqinile kakhulu—njenge-mesh engu-3,000 kuya ku-5,000—ngokuyinhloko kuthuthukisa amandla nokuqina kodwa kwenza buthaka ukumelana nokushelela. Ngakho-ke, ukukhetha kumele kuhambisane nomgomo wakho wokugcina: phansi, ibanga eliqinile linganele; kuma-topcoat ezimboni aphezulu, ibanga eliqinile lingase likhethwe ukuze kukhuliswe ukumelana nokuguguleka ngaphandle kokubeka engcupheni izinga.
Okwesibili, ukulawula okunembile kwenani lokwengeza kubalulekile. Okuningi akulona okungcono ngempela. Lezi zinhlayiya zinamandla adonsela phansi aphezulu, futhi amanani amaningi angabangela ukuqina. Uma ungqimba luhlala isikhathi eside kakhulu, luzohlukana—uwoyela ocacile phezulu, ulwelwesi phansi—oluzokwenza lungasizi ngalutho. Ngaphezu kwalokho, ukwengeza okuningi kakhulu kuthinta kakhulu ukulingana nokukhanya kongqimba, okungenzeka kuholele emphumela ongemuhle wekhasi eli-orenji ebusweni obufafaziwe. Ngokuvamile sithola ibhalansi efanele phakathi kokusebenza, ukusebenza kahle, kanye nezindleko ngokuhlola okuphindaphindiwe.
Okokugcina, ukuhlakazeka kubaluleke kakhulu. Lezi zinhlayiya ezincane zibonisa amandla aqinile e-van der Waals, okubangela ukuba zihlangane. Uma zingahlakazeki kahle, zakha izinhlayiya ngaphakathi kwengubo. Akugcini nje ngokuthi lezi zinhlayiya zehluleke ukuletha izinzuzo, kodwa futhi zidala amaphuzu okucindezeleka anciphisa ukusebenza kwengubo. Ngakho-ke, i-dispersant efanele kumele isetshenziswe kanye nemishini yokusabalalisa enamandla amakhulu ukuqinisekisa ukuthi zonke izinhlayiya ezincane zimbozwe kahle futhi ngokufanayo yi-resin slurry. Kulapho kuphela lapho amandla azo aphelele angagcwaliseka khona.
