Njengoko imfuno yedayimani micropowder iqhubeka nokunyuka, ukusetyenziswa kwayo kumashishini ahlukeneyo kuye kwanda kakhulu. Ukusuka kwizixhobo zokurhawuzelela ukuya kwizixhobo zokusika, ukusuka kwi-elektroniki ukuya kwezonyango, idayimani micropowder idlala indima ebalulekileyo kumacandelo amaninzi obuchwephesha obuphezulu. Nangona kunjalo, ukuhlangabezana neemfuno ezikhulayo zomgangatho, elinye lamanyathelo abalulekileyo kwinkqubo yayo yemveliso kukuhluzwa kobungakanani bamasuntswana.
Emva kokusilwa kwebhola, ukutyunyuzwa, ukubumba, kunye nokucocwa okuqinileyo, i-diamond micropowder isafuna inyathelo elinye elibalulekileyo lokucubungula—ukuhlelwa kobukhulu bamasuntswana. Injongo yale nqanaba kukuqinisekisa ukusasazwa kobukhulu bamasuntswana ngokulinganayo ngelixa kusulwa ngokupheleleyo amasuntswana amakhulu.
Ngenxa yendalo entle yeumgubo wedayimani omncinci, iindlela zemveli ezisekelwe kwisihluzo azinakufikelela ngokuchanekileyo okufunekayo. Ke ngoko, ukwamkela iindlela zesayensi, ezisebenzayo, nezichanekileyo zokuhlela kubaluleke kakhulu. Njengoko kukhula ukusetyenziswa kwedayimani encinci kunye neemfuno zomgangatho ezikhulayo kwimarike, abavelisi badla ngokusebenzisa iindlela ezahlukeneyo zokuhlela. Ezi ziquka ukuhlaliswa kwendalo, ukuhlelwa kwe-centrifugal, ukuhlelwa kwe-overflow, kunye nokuhlelwa kwe-hydrocyclone.
Ulwahlulo lweNdalo lokuHlala
Indlela yokuzinza yendalo isekelwe kumgaqo wokuba, phantsi komxhuzulane ofanayo, amasuntswana anobukhulu obahlukeneyo ahlala ngamanani ahlukeneyo kulwelo. Kule ndlela, amasuntswana ahlulwahlulwa ngokulawula ukuphakama kwexesha lokuzinza.
Xa isuntswana lihamba kulwelo, liphenjelelwa ngamandla amathathu: amandla omxhuzulane wesuntswana, ukuphaphazela kolwelo, kunye nokuxhathisa okwenziwa yi-medium. Isantya sokuzinza kwesuntswana sixhomekeke kwizinto ezifana nendawo yoqhagamshelwano phakathi kwesuntswana kunye ne-medium, i-viscosity yolwelo, kunye nokuxhathisa kokungqubana okufunyanwa yi-medium.
Ulwahlulo lweCentrifugal
Ukuhlelwa kweCentrifugal kusebenza ngomgaqo ofanayo nokumiswa kwendalo kodwa kusebenzisa amandla ecentrifugal aveliswa yicentrifuge ukwahlula i-micropowder. Kwiziqwenga eziqinileyo, ubunzima bazo obukhulu buzivumela ukuba zihlale ngokukhawuleza, kwaye ukumiswa kwendalo kunokwahlula ngokufanelekileyo iziqwenga ezinobukhulu obufanayo. Nangona kunjalo, kwiiziqwenga ezincinci, isantya sokuhlala kancinci phantsi komxhuzulane sandisa kakhulu umjikelo wemveliso, sithatha indawo enkulu kunye nezikhongozeli. Iziqwenga ezi-Ultra-fine zisenokungaphumeleli ukwahlukana ngokufanelekileyo ngenxa yokuhamba kweBrownian kunye nokuphazamiseka kweziqwenga.
Ngokwahlukileyo koko, amandla e-centrifugal akhawulezisa intshukumo yee-microparticles, nto leyo ekhawulezisa inkqubo yokuhlela. Oku kwenza ukuhlelwa kwe-centrifugal kube yimpumelelo enkulu kwii-small particles, nto leyo ephucula kakhulu ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso. Ke ngoko, abavelisi abaninzi badibanisa ukuhlaliswa kwendalo kunye nokuhlelwa kwe-centrifugal ukuze bafumane uluhlu olupheleleyo lwee-fine-to-coarse powders. Le ndlela ye-hybrid iphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.
Ulwahlulo oluPheleleyo
Ukwahlulwahlulwa kokugcwala kunokuqondwa njengendlela yokuhlalisa ngokuphindaphindiweyo. Kwi-classifier yokugcwala, amanzi afakwa ezantsi kwesikhongozeli esijiyileyo. Njengoko amanzi esiya phezulu, isantya sawo siyehla kancinci aze azinze kwicandelo lesilinda phezulu.
Amasuntswana edayimani ahamba ngokuchasene nokuhamba kwamanzi okunyukayo, kwaye xa amandla omxhuzulane kunye namandla achaseneyo elingana phezulu, amasuntswana anobukhulu obuthile aya kuhlala exhonywe emanzini. Amasuntswana amancinci aya kuphuma kwisikhongozeli, ngelixa amasuntswana aqinileyo aya kuhlala kwicandelo eliyi-conical. Ngokulungisa isantya sokuhamba kwamanzi, abavelisi banokufumana iimveliso ezinobukhulu obuthile bamasuntswana.
Nangona ukuhlelwa kokugcwala kucotha kwaye kudla amanzi amaninzi, kubonelela ngocoselelo oluphezulu kwaye kufuna izixhobo zomsebenzi ezimbalwa xa kuthelekiswa nezinye iindlela. Izinto eziphambili ezichaphazela ukusebenza kakuhle kwale ndlela kukumila kwamasuntswana kunye nolawulo lwesantya sokuhamba kwamanzi. Iimilo zamasuntswana ezingahambelaniyo zinokubangela intshukumo engahambelaniyo ngaphakathi kolwelo, nto leyo ephazamisa inkqubo yokwahlulahlula. Ukongeza, ulawulo lokuhamba kwamanzi olungazinzanga lunokubangela ukuxutywa kwamasuntswana arhabaxa nacolekileyo, okuthintela ukwahlukana ngokuchanekileyo.
Ulwahlulo lweHydrocyclone
Ukuhlelwa kwe-hydrocyclone kusebenzisa imigaqo yokuhlalisa i-centrifugal ukwahlula amasuntswana ngokukhawulezisa inkqubo yokwahlulahlula ngokujikeleza ngesantya esiphezulu ngaphakathi kwe-hydrocyclone. Le ndlela isetyenziswa kakhulu ekuhleleni okurhabaxa kunye nokuphelelwa ngamanzi emzimbeni. Iingenelo zayo eziphambili ziquka isantya, ukulula, ukuphindaphindwa okuhle, kunye nokondla rhoqo. Isebenza ngokufanelekileyo kuzo zonke ii-micropowders zedayimani ngaphandle kwezo zincinci kune-2 microns. Nangona kunjalo, ayichanekanga kangako kunezinye iindlela.
Ukukhetha Indlela Efanelekileyo Yokuhlela
Indlela nganye yokuhlela ineengenelo kunye neengxaki zayo. Kwimveliso yokwenyani, abavelisi banokukhetha eyona ndlela ifanelekileyo ngokusekelwe kwiimfuno zabo ezithile. Abanye banokukhetha indlela enye yokuhlela, ngelixa abanye banokudibanisa iindlela ezininzi ukuze bafumane iziphumo ezilungileyo. Ngokukhetha ngononophelo nangokudibanisa iindlela zokuhlela, iinkampani zinokuqinisekisa ukuba iimveliso zabo zedayimani micropowder ziyahlangabezana nemigangatho ephezulu yomgangatho.
Njengoko imakethi yeumgubo wedayimani omncinciNjengoko kuqhubeka nokukhula, uphuhliso lwetekhnoloji yokuhlela ephucukileyo luya kuba yimfuneko ekuhlangabezaneni nemfuno ekhulayo yeemveliso ezichanekileyo nezisebenzayo kumacandelo amaninzi.
