Ipulatifomu yegranite, njengethuluzi lokubhekisela ekulinganisweni nasekucutshungulweni okunembile, ukugcinwa kwayo ngokunemba kuthinta ngqo ikhwalithi yokukhiqiza. Okulandelayo kunikeza uhlelo lokulungisa oluhlelekile oluhlanganisa ukulawulwa kwemvelo, ukugcinwa kwansuku zonke kanye nokulinganiswa kobungcweti ukuqinisekisa ukuthi ipulatifomu igcina ukunemba kwezinga le-nanometer isikhathi eside.
1. Ukulawulwa Kwemvelo: Yakha isithiyo sokuvikela ngokunemba
Ukuphathwa kwezinga lokushisa kanye nomswakama
Izinga lokushisa lendawo yokusebenza lidinga ukuzinziswa ku-20±1℃. Ukushintshashintsha ngakunye kwe-1℃ kuzobangela ukuguquguquka kokushisa kwepulatifomu yegranite ku-0.5-1μm/m. Uhlelo lokushisa olungaguquguquki lungafakwa eshabhu ukuvimbela izindawo zokungenisa umoya ukuthi zingavuthi ngqo epulatifomu.
Umswakama kufanele ulawulwe phakathi kuka-40% no-60%. Umswakama owedlulele ungabangela ukugqwala kalula ezingxenyeni zensimbi, kanti umswakama ophansi kakhulu ungaholela ekuphazamisekeni kukagesi ongashintshi ekulinganisweni.
Ukuhlukaniswa kokudlidliza
Ipulatifomu kufanele igcinwe kude nemithombo yokudlidliza njengemishini yokunyathela kanye nemishini yokugaya. Kunconywa ukugcina ibanga elingaphezu kwamamitha amathathu ukusuka emishinini yokudlidliza.
Uma ukudlidliza kungenakugwenywa, ama-absorber okushaqeka kwentwasahlobo yomoya angafakwa phansi kwepulatifomu ukuze kuncishiswe umthelela wokudlidliza kwemvelo ekusithekeni kwepulatifomu (okunganciphisa ukudlidliza kwangaphandle ngamaphesenti angaphezu kuka-80).
2. Ukulungiswa Kwansuku Zonke: Ukulawula ngokucophelela kusukela ekuhlanzeni kuya ekuvikeleni
Imininingwane yokuhlanza indawo
Ukususwa kothuli: Sula indawo ngesikhumba senyamazane noma indwangu engenalo ulwelwesi ngendlela efanayo nsuku zonke ukuze uvimbele izinhlayiya zothuli (≥5μm) ukuthi zingaklwebhi ipulatifomu. Amabala aqinile angasulwa ngobumnene nge-anhydrous ethanol (ubumsulwa ≥99.7%). Izinyibilikisi ezinamandla njenge-acetone akumele zisetshenziswe.
Ukususa amafutha: Uma ihlangana namabala kawoyela, yisule ngesihlanzi esingathathi hlangothi esixutshwe amanzi, bese ugeza ngamanzi ahlanzekile bese womisa ngomoya ukuze uvimbele uwoyela wamaminerali ukuthi ungangeni ezimbotsheni ezincane zepulatifomu.
Ukuvikelwa komthwalo nokushayisana
Umthamo wokuthwala umthwalo wepulatifomu kufanele ulawulwe ngaphakathi kwama-70% omthwalo olinganisiwe (isibonelo, kwipulatifomu engu-1000kg, kunconywa ukuthi umthwalo ube ≤700kg) ukuze kugwenywe ukuguquguquka okungapheli okubangelwa ukugcwala kwendawo.
Akuvunyelwe ngokuphelele ukushaya izinto zokusebenza epulatifomu. Uma uphatha amathuluzi, gqoka amagilavu athambile ukuvimbela izinto ezibukhali ukuthi zingaklwebhi ubuso (imiklwebhu enokujula okungaphezu kuka-20μm izothinta ukulinganiswa kwendlela yokukhanya eboniswayo).
3. Ukulinganisa Kobungcweti: Umongo wokugcina ukunemba ngokwesayensi
Ukusetha umjikelezo wokulinganisa
Izimo zokusetshenziswa ezivamile: Linganisa kanye njalo ngekota bese usebenzisa i-laser interferometer ukuthola ukuthi i-flat ingakanani (ngokunemba okungu-±0.5μm/m).
Ukusetshenziswa kwemvamisa ephezulu noma izindawo ezinzima: Ukulinganiswa kwanyanga zonke, kugxilwe ekuqapheni izindawo ezizwela ukushisa (njengomphetho wepulatifomu eduze kwemithombo yokushisa).
Ukucutshungulwa ngemva kokulinganisa
Uma kutholakala ukuphambuka kokuthamba (njengokungaphezulu kuka-± 1μm/m), kumele kugaywe futhi kulungiswe uchwepheshe ochwepheshe osebenzisa i-W1.5 micro-powder. Ukuzigaya nge-sandpaper akuvunyelwe ngokuphelele.
Ngemva kokulinganiswa, idatha kufanele iqoshwe futhi igcinwe, futhi kufanele kusungulwe ijika lokunciphisa ukunemba kwepulatifomu ukuze kubikezelwe izidingo zokugcinwa kusengaphambili.
4. Isitoreji Nokuthutha: Gwema ukulahleka kokunemba okufihliwe
Amaphuzu ayisihluthulelo okugcina isikhathi eside
Uma igcinwa, kufanele imbozwe ngesembozo esingangeni umswakama futhi esingangeni uthuli. Iphansi kufanele lisekelwe ngamaphuzu amathathu (indawo yokusekela itholakala ku-2/9 yobude bepulatifomu) ukuvimbela ukugoba okubangelwa amandla adonsela phansi (ipulatifomu eyimitha eli-1 ingase igobe ngo-0.3μm ngenxa yokusekelwa kwephuzu elilodwa isikhathi eside).
Susa indawo yamaphoyinti okusekela epulatifomu njalo (njalo ngenyanga) ukuze ugweme ingcindezi yendawo yesikhathi eside.
Uhlelo lokuvikela ezokuthutha
Ukuhamba ibanga elifushane: Songa nge-foam emunca ukushaqeka, lungisa ngaphakathi kohlaka oluqinile, bese ugcina ukusheshisa kungakapheli ama-2g.
Ukuthuthwa kwebanga elide: Kudingeka kufakwe i-vacuum cleaner futhi kugcwaliswe nge-nitrogen eyomile. Ngemva kokufika, kufanele kushiywe amahora angama-24 kuze kube yilapho izinga lokushisa lifinyelela ukulingana ngaphambi kokuyivula ukuze kuvinjelwe amanzi anomswakama ukuthi angaphazamisi ukunemba.
5. Ukubikezela Amaphutha: Amasu Okuhlonza Izinkinga Zasekuqaleni
Ukuhlola okubonakalayo: Bheka njalo indawo ngengilazi yokukhulisa engu-40x. Uma kutholakala imihuzuko eqhubekayo noma ukwehla okukhulu kokucwebezela, kungase kubonise ukwehla kokunemba.
Ukutholwa komsindo: Thepha ipulatifomu kancane. Uma umsindo uba nomsindo oqinile (ngokuvamile kufanele ube umsindo ocacile), kungase kube nokuqhekeka okuncane ngaphakathi. Yeka ukuyisebenzisa ngokushesha ukuze utholakale.
Ngalesi simiso sokulungisa, ipulatifomu ye-granite ye-ZHHIMG® ingagcina ukuqina okungu-±1μm/m iminyaka eyi-10, okungaphezu kokuphindwe kathathu kunokuphila okunembile kwamapulatifomu anganakekelwa kahle. Umkhuba ubonisile ukuthi ngemva kokuba ifektri ethile ye-semiconductor yamukele lesi sixazululo, imvamisa yokulinganiswa kwepulatifomu yehliswe ngo-50%, futhi izindleko zokugcinwa zonyaka zongiwe ngama-yuan angaphezu kuka-150,000.
