The I-Ultrasonic Planetary Ball Mill umshini owenzelwe ukugaya izinto eziqinile. Futhi uwumshini okwazi ukuhlinzeka ngenqubo yokugaya enembile kakhulu. Lokhu kungenxa yokuthi umshini usebenza ngesivinini esiphezulu kakhulu.
Ama-nanoparticle ayizinhlayiya ezincane ezinobubanzi obungaphansi kwama-nanometer ayi-100. Anezakhiwo ezahlukahlukene zomzimba eziwahlukanisa nezinhlayiya ezincane. Nakuba zingabonakala nge-microscope ye-electron, azikwazi ukubonwa nge-microscope ejwayelekile yokukhanya.
Ama-nanoparticles avele ngenxa yokuhlanganiswa kwesidingo sezinhlayiya ezincane kanye nekhono lokushintsha izakhiwo zazo. Abacwaningi baqamba igama elithi "nanoparticles" ngawo-1990. Kodwa-ke, leli gama alizange lisetshenziswe kabanzi e-United States kwaze kwaba yilapho kuqaliswa i-National Nanotechnology Initiative.
Ama-nanoparticles anezindlela eziningi zokusetshenziswa. Isibonelo, ekwelapheni udayi wezindwangu. Ngaphezu kwalokho, ezinye izindlela zokusetshenziswa zingadinga izimo noma osayizi abathile. Olunye uhlobo lomkhiqizo olutholakala emakethe yi- umshini wokugaya ibhola weplanethi webhubhu.
Ukugaya ibhola kuyinqubo yokugaya ngomshini esebenzisa amandla aseceleni ukukhipha amabala ento. Ukugaya ibhola kusetshenziselwa ukudala izinto ezihlukahlukene ezinobukhulu obungajwayelekile kanye nobuso obuvezwe kakhulu. Le ndlela ivame ukusetshenziswa ekuhlanganiseni i-oxide, kodwa ingasetshenziswa futhi ukudala ama-nanocomposites. Siphenye umphumela wokugaya ibhola kuma-nanopowders e-MoS2 kulolu cwaningo.
Ngemva ukugaya ibhola le-nano, isakhiwo sekristalu sama-fibril sahlala sizinzile. Ngakolunye uhlangothi, iphrofayili yokuwohloka kokushisa kwama-fiber yathonywa. Ngaphezu kwalokho, ukugaya ibhola kwasheshisa ukubola kwezinto.
Isikhathi sokuphendula kanye nokufakwa kwamandla kuqhathaniswe. Imiphumela ibonise ukuthi ukusebenzisa umshini wokugaya ibhola kanye nezinsiza zokugaya kuholele ekwandeni okukhulu endaweni ethile yobuso.
The iplanethi yebhola yokugaya iyithuluzi elihle kakhulu lokugaya, ukuxuba, nokugaya izinto eziqinile ngoba zisebenza kahle kakhulu, ziphephile, futhi ziyasebenziseka ngezindlela eziningi. Le mishini enamandla amakhulu ingakhiqiza izinhlayiya ezincane ezinobukhulu be-nanometer. Inezinhlelo zokusebenza eziningi, okuhlanganisa ukudla, imithi, kanye nokulungiswa kwemvelo.
I-RETSCH ikhiqiza umugqa ogcwele wemishini yokugaya ibhola kanye nemishini yokuxuba. Le mishini ingagaya izinto ezithambile neziqinile kokubili ezimanzi nezomile. Kunezinhlobo eziningana ezitholakalayo, kusukela kumamodeli amancane ebhentshi kuya ezinhlotsheni zokuma phansi ezineziteshi eziningi zokugaya. Isivinini esiguquguqukayo siyatholakala kwamanye amamodeli.
Ama-Retsch ball mills aklanyelwe ukusebenza kahle nokuphepha okuphezulu. Ama-planetary ball mills awo ahlukaniswa ngezici eziningana, kufaka phakathi i-Safety Slider eqinile. Le divayisi ezisebenzela yona iqinisekisa ukuthi imbiza yokugaya ihlezi kahle. Iphinde ivimbele ukulahleka kwesampula okungaba yingozi.
I-Laboratory planetary ball mill Kusetshenziswe ezikalini zokuhlola ukunciphisa usayizi wezinhlayiya iminyaka eminingana. Okutholakele kubonisa ukuthi ukugaya ibhola leplanethi kuyindlela ephumelelayo yokunciphisa izinhlayiya ezinkulu. Kodwa-ke, amapharamitha okucubungula esistimu ethile athonya izakhiwo zomkhiqizo wokugcina. Lokhu kubuyekezwa kugxile emthonjeni wejubane lokuguquka, isikhathi sokugaya, isilinganiso sokugcwalisa, kanye nemidiya yokugaya ekuvuneni nasekuhlanganisweni kwezinhlayiya ze-nano.
Ukugaya ibhola kuyinqubo yomshini ehlukanisa izimbulunga futhi ikhiqize osayizi bezinhlayiya ezincane. Ingasetshenziswa ukwenza izimpushana ze-metal matrix composite. Ukuhlanganiswa kwemishini kusetshenziswe kulolu cwaningo ukudala izimpushana ze-alloy ze-nanocrystalline Al 6061.
Indlela ye-X-ray diffraction (XRD) yasetshenziswa ukuhlonza isakhiwo sekristalu sesandulela. Ngaphezu kwalokho, kwenziwa i-electric resistivity kanye ne-MAPssbauer spectroscopy.
Isikhungo sokukhiqiza saseTencan sisabalale kumamitha-skwele angu-20,000 kanye nesikhungo saso socwaningo nentuthuko sihlanganisa ama-skwele angu-2,000. Lokhu kuqinisekisa ukuthi iTencan iyakwazi ukuhlangabezana nazo zonke izidingo zamakhasimende. ITencan ithole amalungelo obunikazi angaphezu kuka-30, futhi inobambiswano nodokotela bezokwelapha abangu-20 abavela emanyuvesi amahlanu adumile.
Ukugxila okuyinhloko kwebhizinisi lenkampani yizindawo ezintathu: ukukhiqizwa kwemishini yempuphu, ubuchwepheshe bempuphu, kanye nezinto zempuphu. Imikhiqizo yethu yamanje ifaka phakathi imishini yokugaya yamaplanethi elabhorethri, imishini yokuchoboza nokuchoboza kanye nokuhlola, ukuxuba, ukuxubha kanye nemishini.
Le nkampani iqede ngempumelelo uhlelo lokulawula ikhwalithi lwe-ISO9001, i-CE, i-SGS, noma ezinye izitifiketi zesistimu. Ngaphezu kwalokho, le nkampani inobuchwepheshe obune-patent obungaphezu kuka-40 obuyisisekelo, ngabunye bunamalungelo abo obuhlakani empahla. Iqinisekiswe nguhulumeni njenge "bhizinisi lobuchwepheshe obuphezulu eSifundazweni saseHunan".
Izikhungo zocwaningo, amanyuvesi kanye nezinkampani ezisekelwe kubuchwepheshe yizo amakhasimende amakhulu. Zikhonza amakhasimende angaphezu kuka-20,000 emhlabeni jikelele futhi zithumela kwamanye amazwe angaphezu kuka-60.
The umshini wokugaya ibhola weplanethi webhubhu iyithuluzi elihle kakhulu lokusetshenziswa ocwaningweni nasemalebhu. Le mishini inokufakwa kwamandla aphezulu futhi ingakhiqiza izinhlayiya ezinobukhulu be-nanometer. Isebenza kahle kakhulu ekuhlanganisweni kwama-polymer. Ngokuvamile igaya imizuzu engama-30 kuya kwengama-60. Izigayo zamabhola eplanethi nazo zingashintshwa ukuze zifake izakhi zokulawula izinga lokushisa, ngaphezu kwalezi zinzuzo.
I-planetary mill esebenza kahle kakhulu ingagaya amasampula ngokuphindwe izikhathi ezingu-95 zamandla adonsela phansi. Amandla e-centrifugal ezitsha ezijikelezayo yiwo abangela lokhu. Umphumela uphinde uthintwe yisilinganiso soketshezi kuya koqinile sesampula kanye nohlobo loketshezi olusetshenzisiwe.
Usayizi webhola uyisici esibalulekile esithonya umkhiqizo womshini wokugaya. Ngokuvamile, uma amabhola emakhulu, amandla okushaya ayanda. Kodwa-ke, ububanzi bebhola abuyona njalo indlela ethembekile yokubikezela ukwehla kwamandla kwangempela.
