Ukuhlolwa kwama-blade enjini ye-aero kunezidingo eziphakeme kakhulu zokuqina, ukunemba kanye nokuthembeka kwepulatifomu. Uma kuqhathaniswa namapulatifomu okuhlola endabuko njengensimbi ecijile kanye ne-aluminium alloy, amapulatifomu e-granite abonisa izinzuzo ezingenakuphikwa ezinkomba eziningi ezibalulekile.
I. Ukuzinza Kokushisa: "Isivikelo Semvelo" Esimelene Nokuphazamiseka Kokushisa
I-coefficient yokwanda kokushisa kwamapulatifomu ensimbi ephonswe cishe ingama-10-12 ×10⁻⁶/℃, kanti eye-aluminium alloys iphakeme njengo-23 × 10⁻⁶/℃. Ngaphansi kokushisa okubangelwa ukusebenza kwemishini yokuthola noma ukuguquguquka kokushisa kwemvelo, ukuguqulwa kobukhulu kungenzeka, okuholela emaphutheni okuthola. I-coefficient yokwanda kokushisa kwepulatifomu ye-granite ingu-(4-8) × 10⁻⁶/℃ kuphela. Ngaphakathi kokushintshashintsha kokushisa okungu-±5℃, ushintsho lobukhulu lwepulatifomu ye-granite engamamitha ayi-1 ubude lungaphansi kuka-0.04μm, okungacishe kunganakwa. Lesi sici sokwanda kokushisa okuphansi kakhulu sinikeza indawo yokubhekisela ezinzile yemishini yokunemba efana nama-laser interferometers kanye nemishini yokulinganisa enama-coordinate amathathu, kugwema ukuphambuka kokulinganisa kwemigqa ye-blade okubangelwa ukuguqulwa kokushisa.
Ii. Ukusebenza Kokulwa Nokudlidliza: "Isithiyo Esisebenzayo" Sokuqeda Ukuphazamiseka Kokudlidliza
Eshabhu lokukhiqiza izindiza, ukudlidliza kwemvelo okubangelwa ukusebenza kwamathuluzi omshini kanye nokuhamba kwabasebenzi kuvame kakhulu. Amapulatifomu e-aluminium alloy awanele ukuqina, kanti amapulatifomu ensimbi ensimbi anamandla okudambisa, okwenza kube nzima ukuvimba ukudlidliza ngempumelelo. Isakhiwo sekristalu esiminyene ngaphakathi kwepulatifomu ye-granite siyinika izici ezinhle kakhulu zokudambisa, ngesilinganiso sokudambisa esingu-0.05-0.1, okuphindwe kahlanu kunensimbi ensimbi ensimbi kanye nokuphindwe kayishumi kune-aluminium alloy. Lapho ukudlidliza kwangaphandle kudluliselwa epulatifomu, kunganciphisa amandla okudlidliza ngaphezu kuka-90% ngaphakathi kwemizuzwana engu-0.3, okuqinisekisa ukuthi imishini yokuthola isakwazi ukukhipha idatha enembile endaweni edlidlizayo.
Iii. Ukuqina Nokumelana Nokuguguleka: "Inqaba Eqinile" Eqinisekisa Ukunemba Kwesikhathi Eside
Ngemva kokusetshenziswa isikhathi esithile, ipulatifomu yensimbi ephonswe ithambekele ekuqhekekeni kokukhathala, okuthinta ukunemba kwayo. Amapulatifomu e-aluminium alloy anobunzima obuphansi kanye nokumelana nokuguguleka okubi, okwenza kube nzima ukumelana nokusetshenziswa njalo kwemishini yokuhlola enzima. Ubuningi bepulatifomu ye-granite bufinyelela ku-2.6-2.8g / cm³, amandla ayo okucindezela adlula i-200MPa, kanti ubunzima bayo be-Mohs bungu-6-7. Uma ithwalwa imithwalo esindayo kanye nokungqubuzana kwesikhathi eside okuvela emishinini yokuhlola ama-blade, ayithambekele ekugugeni noma ekuguqukeni. Imininingwane evela enkampanini ethile yezindiza ikhombisa ukuthi ngemva kokusetshenziswa okuqhubekayo iminyaka eyisishiyagalombili, ushintsho lwesicaba sepulatifomu ye-granite lusalawulwa ngaphakathi kuka-±0.1μm/ m, kuyilapho ipulatifomu yensimbi ephonswe idinga ukulinganiswa kabusha ngemva kweminyaka emithathu kuphela.
Iv. Ukuzinza Kwamakhemikhali: "Itshe Legumbi Eliqinile" Lokuzivumelanisa Nezimo Eziyinkimbinkimbi
Ama-reagent amakhemikhali afana nama-cleaner kanye nama-lubricant avame ukusetshenziswa ezindaweni zokuhlola izindiza. Amapulatifomu e-aluminium alloy athambekele ekugqwaleni, futhi amapulatifomu ensimbi ensimbi angathinteka ekunembeni ngenxa ye-oxidation kanye nokugqwala. I-granite yakhiwe kakhulu ngamaminerali afana ne-quartz kanye ne-feldspar. Inezakhiwo zamakhemikhali ezizinzile, ububanzi bokubekezelela i-pH obungu-1 kuya ku-14, futhi ingamelana nokuguguleka kwezinto zamakhemikhali ezivamile. Akukho ukuna kwe-ion yensimbi ebusweni bayo, okuqinisekisa indawo ehlanzekile yokubona nokugwema amaphutha okulinganisa abangelwa ukungcola kwamakhemikhali.
V. Ukunemba Kwemishini: "Isisekelo Esifanele" Sokulinganisa Okunembile
Ngobuchwepheshe obunembile kakhulu njengokupholisa nge-magnetorheological kanye nokucubungula nge-ion beam, amapulatifomu e-granite angafinyelela ukunemba kokucubungula okungu-±0.1μm/m ukuze kube yisicaba kanye no-Ra≤0.02μm ukuze kube yisicaba, okudlula kakhulu amapulatifomu ensimbi ensimbi (±1μm/m ukuze kube yisicaba) kanye namapulatifomu e-aluminium alloy (±2μm/m ukuze kube yisicaba). Lobu buso obunembile kakhulu buhlinzeka ngereferensi yokufaka enembile yezinzwa ezinembile kakhulu kanye nama-probe okulinganisa, okwenza kube lula ukuqashelwa kokulinganiswa kwe-contour okunezinhlangothi ezintathu kwama-blade enjini ye-aero ezingeni lika-0.1μm.
Ezimweni ezifunwa kakhulu zokuhlolwa kwe-blade yenjini ye-aero, amapulatifomu e-granite, anezinzuzo zawo eziphelele ekuzinzeni kokushisa, ukumelana nokudlidliza, ukuqina, ukuqina kwamakhemikhali kanye nokunemba kokucubungula, abe yisinqumo esingcono kakhulu sokuqinisekisa ukunemba nokuthembeka kokuhlolwa, okubeka isisekelo esiqinile sentuthuko yekhwalithi ephezulu yokukhiqiza izindiza.
