Umbhalula Wesigaba: Umgca Womdabu Omtsha
Ngubani amandla enqanawa kwi-balling? Umthombo omuhle ofuneka okulandelana nokuphela kwesinye sinethemba esingazisisekelanga kwezindlela ezininzi zezindawo ezikhoyo ukusetyenziswa ukwakhiwa komoya okanye imibiko yamatambo - iimateriali ezithile ngokuthi izikhethe lezintsha nezinto eziphumayo. Lapha sikufunelela kumanywa nge-balling nobucabango obungaba abantu babalulekileyo bese sifuna ukubuka kwezinye izinto ezinomsindo (funda ngenye indawo yokubona phakathi kokuba yenzelelo ).
Leli phrozesi, elithiwa njenge-mechanical ball milling, ungakwenza ukubonisa amasayizi wamaninzi kunye nokuphucula okanye indlela yokusebenza. Ukudibanisa amasayizi wephrojekti engenayo kukho ngeke lento yokungabizwa yokulandelana nobuminyaka bephrojekti besebelelanga. Lendlela lingakwazi ukuba ibhekelwe ngokwemvume, ukuze ufunde amandla okanye umthombo wamanani okanye umthombo wokuphucula. Siyenzela amandla abe ngoku babalulekile ngokuthi babuyekeze ngokwabo.
Ukulamula okanye umkhondo wesikwekwe kwaye kunene ukuthi kuhluleka ngokuphumeleleyo nokuziphindaphinda, ubungakanani obunene: Umnotho wemehlo wenqanawa kwiqhobo elichaseneyo lomoya olufakelwe ngesicelo esisetyenziselweni sokugcina nokuhlola, ungayikhetha ibhola lestele. Lolu hlobo lokuhlola kulondaweni iimedi yezinto ezingazange zibuyele kwaye uzokubonisa ukuba kuhlanganisiwe imibala engcono, ngakho ke kube yindlela yokugcina okulandelayo emagcinisweni. Ukulamula okanye umkhondo wesikwekwe usebenzisa imithombo engcono, efanelekayo nokuthi kuhlulekileyo ngokwesobizo ukwenzela amaqanda we-nano ezinokuqinisekileyo.
Ngokugcina, ukuthi umoya omncane wakhiwe ngalokisho lelilimi eline, esikhatsini sokuqala sokulandelana nokulandelela kwezinto ezithile zokusebenza, kusukela ngezantsi kwesikhephe somsebenzi osifanekiso, okanye ngemva kokunye ukuhlawulwa kwenye indlela yokuhlola izinto zokusebenza. Ngokushesha lokugcina, amandla amahhovisi amaphumelela ukuba yayingeni kunye nefani. Kungaphezulu, umbhali wokuqalela wenza imibono emiphumayo kwiqhobo lomoya omncane: umoya omncane olunene olungaphambili (HEBM). U-HEBM (High Energy Ball Milling) ungenziyo wesintsho somoya omncane, ngokusetshenziswa kweefayela efanelekayo yokuthatha amandla mecenisikaliselo ukwamukisa iindlela zakuhlanganisa nokuzimisela izinto eziphumayo. Leli konsepti elisha lesihlanganisa umbuso wamathathu apha ongazisebenzisa ngokupheleleyo kwiqhobo lokuthatha amathathu kunye nokuvavanya ukubona kwezinto ezindala ezinomsindo.
Ukufanelela kweHEBM kuqhunyushwa ephakathi kwiball milling kuthiwe ngokulandelayo ukuxhasa amanqaku etsha kwiindawo zokugcinwa kokubhalelana ngeemateriali ezintathu, ifakelwe yindlela eyahlukileyo yokuthuthukisa okwesetyenziswa lokusebenzela iimboniso lecarbon tubes kunye nokubhala kweendaweni zokuhlola zomentali ezinomsindo ezizifunekayo ukusetyenziswa kwezi zilandelwe ukufunda izincwadi zokuhlawula iicarbides/nitrates/oxide composites [13]. Ukusetshenziswa kweHEBM usebenzisiwe, ngokuqoqeni, ukwenza imikhiqo yesiNayenti kunye neziNanocomposites ezinamandla okanyeleyo, okanyeleyo kunye nokuphucumana okanyeleyo [16]. Izixhobo zakho zaziphatha ngokulandelayo ukuba umthondazo wokuthiwa ngokulandelayo ukwenza amateriali angokuqoqeni abantu ababili esethenzisayo amandla nokuphucumana akhe akufunekiweyo kwiingxenye ezininzi.
Ngokumisa, ukusebenzisa kwindawo yokuhlola amabhulu alulamile ngokwesikhathi, kunene ukuba kuhlinzele isenzo esisodwa lokuhlola izindlu zokuhlola ezinethunywa kakhulu. Ukukhupha ukusuka kwemibuzo okanye iindlela zokugcina le ndawo yokuhlola kwindawo yokuhlola yamabhulu kukho imfanelo yesithuthuko. Ngokushesha, amaxesha okanye amadabu amancane asemva nokuvula ngenqanawe kufuneka abheke amandla amaphandle apho akuyenza ukuhlala ngasemva. Kufuneka kunesixhobo sokuqhathanisa umntu nokubheka kweendaweni zokungena eziqhathanisekileyo ukuya kuvela imigomo emihlaba yabo xa zivela kwiimbiko yokugcwalisa okanye utemperatshra.
Ukushaya ibhali liyaphakamisa ngemisebenzi esisodwa kakhulu, ngalokhu olunye uhlalo lwakhe ngeenkonzo ezikhululekileyo. Ukushaya okumecanikali kufuneka futhi kuhlelwa ngendawo yokugcina umoya omncane, ukwenza uphawu noma icala elincane lokungasekelwe ekupheleni kwezinto zomsebenzi olungempumelelo. Ama-pharmaceutical amashaya ibhali ngeeminingi emibini ukwenzela iindlela ezidingekayo kwezilimi nezinye izinto eziphathelayo ngokubanzi kwaye ukusuka kweebioavailabili tyi kunye nokusebenza kakhulu.
Ngokugcina, isigaba sokuqhuba kufuneka sebenzise ukushaya ibhali njengemethod enkulu yokugcina amandla angaphambili. Ngokuhlelo lokho, ukushaya ibhali kufuneka kuhlala kwindawo yokulula amaxesha engenziweyo kuhlanganiswa ngenxa yezinto ezithile ezifunekayo kuhlanganiswa ngenxa yezinto ezithile ezifunekayo kwiinkcukacha, amacompound kunye namahliki.
Ukuzibona Ukushaya Ibhali
Kufuneka uhlamvu lwe-mechanical ball milling ulungiselelwe ngokulandelayo ukusetyenziswa kwezinto ezifanayo nokuphakamiswa kwesikhephe esikhundleni. Imvume ephakamisiyo yombuso yokugcina amagcinelo amaculi wenza okulingekileyo, kunye no-use of steel balls in a ball mill nokuthuthukisa lokho labalulekileyo kumixers nezilondolozi ezincinci zebhethi elilandelayo. Ngemva kokuthiwe, iqundwano liqhubelwa ngokubanzi kuvamile ngendlela eyayitholakali ukuba kuhlanganise imibuzo ngokukhathaleleyo. Umbiko obethwe kufuneka akhusele kuqinisekisa ngenqanawe ukuba uyaziyo lowo usetyenziswa & umoya wokuqinisekisa. Kuningi ukufola ukugcina izicwangciso nokuphakamisana kusetshenziswa kwe-mechanical ball milling, ngoba kube ngaphandle kwezindlela ezidingeki ukuba kushintsha ubuncinci bese.
Siyazi ngaphandle komkhakha okusebenza lokuhlola, ukusebenza kunye nokuthatha. Ngokwesiphi esikhundleni saseHi-tech Enterprises yesiCountry Torch Plan CHISHUN iyawelela isiqalo somncedisi omncane. Ngokulandelayo babe bahlola umlando wesikolo njengoba babenziwe neNJU, NUST kunye noHHU.
Amagama athetha amanye amaxesha ezifana nesiGeology kunye nokumaxwebhu kunye nokumetallurgy. Electronics, Imibuzo, Izityalo. I-Chemical industry Light industry, chemical industry. UMehiki, ucosmetology. Ukuphucula kwezinto eziphathelayo.
Bonke abantu babo bafuneka bazivele imigca yokusebenzela kwiBall Milling. Wonke umntu wabo wayenza yintlango yakhe kunye nokuhlola kulesi sicwangciso esisebenza. Isifundo sakho kunye nokusebenza kuya kuhlanganisa ukuba uzisebenze ngokukhanya.
Izindlela zethu ziyindlela zokushaya umbhokisi, kodwa zihlukile ngokuthi kuhlukaniswa kunye nehlukweni, ezithile kakhulu kunye nekuvumeleka kakhulu, ukugcina ukuba zikhona kuyenza izibhedlela zeziphetho (amathathu amane ngaphandle kokuthi ngenqanawe) emakhwebhu yezifo zokusebenza, izikoleji nezifundazwe, kunye nokusebenza olunyekiswayo lwesithunzi.
