Izinto ezingavamile ze-magnetostrictive zomhlaba
Uma into ifakwe uzibuthe endaweni kazibuthe, izonwebeka noma ibe mfushane iqonde kumagnetization, okubizwa ngokuthi i-magnetostriction. Inani le-magnetostrictive lezinto ezijwayelekile ze-magnetostrictive yi-10-6-10-5 kuphela, encane kakhulu, ngakho-ke izinkambu zesicelo nazo zilinganiselwe. Kodwa-ke, eminyakeni yamuva nje, kutholakale ukuthi kunezinto ze-alloy kuma-alloys angavamile emhlabeni amakhulu izikhathi ezingu-102-103 kune-magnetostriction yasekuqaleni. Abantu babhekisela kule nto ene-magnetostriction enkulu njengezinto ezingavamile zomhlaba ezinkulukazikazibuthe.
I-Rare Earth giant magnetostrictive materials iwuhlobo olusha lwezinto ezisebenzayo ezisanda kuthuthukiswa amazwe angaphandle ngasekupheleni kwawo-1980. Ikakhulukazi isho izinhlanganisela ze-intermetallic zensimbi yomhlaba ezingavamile. Lolu hlobo lwezinto lunenani elikhulu kakhulu le-magnetostrictive kunensimbi, i-nickel, nezinye izinto. Eminyakeni yamuva nje, ngokuncipha okuqhubekayo kwezindleko zemikhiqizo ye-rearth giant magnetostrictive materials (REGMM) kanye nokwanda okuqhubekayo kwezinkambu zokufaka izicelo, isidingo semakethe siye saba namandla kakhulu.
Ukuthuthukiswa Kwezinto Ezingavamile Zezibuthe Zomhlaba
I-Beijing Iron and Steel Research Institute yaqala ucwaningo lwayo ngobuchwepheshe bokulungiselela i-GMM ngaphambilini. Ngo-1991, kwaba ngeyokuqala e-China ukulungisa imigoqo ye-GMM nokuthola ilungelo lobunikazi likazwelonke. Ngemva kwalokho, ucwaningo olwengeziwe kanye nokusetshenziswa kwenziwa kuma-transducer angaphansi kwamanzi aphansi kwamanzi, ukutholwa kwamanje kwe-fiber optic, ama-transducer welding we-ultrasonic anamandla amakhulu, njll., kanye nokukhiqiza okudidiyelwe okudidiyelwe kobuchwepheshe be-GMM kanye nemishini enamalungelo azimele empahla yengqondo namandla okukhiqiza wonyaka. amathani athuthukiswa. Impahla ye-GMM eyakhiwe yi-Beijing University of Science and Technology ihlolwe ngamayunithi angama-20 ngaphakathi nakwamanye amazwe, kwaba nemiphumela emihle. I-Lanzhou Tianxing Company iphinde yasungula ulayini wokukhiqiza onamandla okukhiqiza amathani waminyaka yonke, futhi yenze impumelelo ebalulekile ekuthuthukisweni nasekusetshenzisweni kwemishini ye-GMM.
Nakuba ucwaningo lwaseShayina nge-GMM luqale kungakephuzi kakhulu, lusasezigabeni zokuqala zokusungulwa kwezimboni kanye nokuthuthukiswa kwezicelo. Njengamanje, i-China ayidingi nje kuphela ukwenza impumelelo kubuchwepheshe bokukhiqiza be-GMM, imishini yokukhiqiza, nezindleko zokukhiqiza, kodwa futhi idinga ukutshala amandla ekuthuthukiseni amadivaysi okufaka isicelo. Amazwe angaphandle anamathisela ukubaluleka okukhulu ekuhlanganisweni kwezinto ezisebenzayo, izingxenye, namadivayisi okusebenza. Izinto ze-ETREMA e-United States ziyisibonelo esijwayelekile kakhulu sokuhlanganiswa kocwaningo nokuthengiswa kwedivayisi yesicelo. Ukusetshenziswa kwe-GMM kuhilela imikhakha eminingi, futhi abangaphakathi embonini nosomabhizinisi kufanele babe nombono wamasu, ukubona kusengaphambili, kanye nokuqonda okwanele ngokuthuthukiswa nokusetshenziswa kwezinto ezisebenzayo namathemba okusebenza abanzi ekhulwini lama-21. Kufanele baqaphe ngokucophelela ukuthambekela kwentuthuko kulo mkhakha, basheshise inqubo yayo yokusungulwa kwezimboni, futhi bakhuthaze futhi basekele ukuthuthukiswa nokusetyenziswa kwemishini yokufaka isicelo ye-GMM.
Izinzuzo Rare Earth Magnetostrictive Materials
I-GMM inezinga eliphezulu lokuguqulwa kwamandla kagesi kagesi, ukuminyana kwamandla aphezulu, isivinini sokuphendula esiphezulu, ukwethembeka okuhle, kanye nemodi yokushayela elula ekamelweni lokushisa. Yilezi zinzuzo zokusebenza eziholele ezinguqukweni zenguquko ezinhlelweni zendabuko zolwazi lwe-elekthronikhi, amasistimu ezinzwa, amasistimu wokudlidliza, njalo njalo.
Ukusetshenziswa kwe-Rare Earth Magnetostrictive Materials
Ekhulwini elisha elikhula ngokushesha lobuchwepheshe, kuye kwethulwa amadivayisi angaphezu kwe-1000 GMM. Izindawo ezisetshenziswa kakhulu ze-GMM zifaka lokhu okulandelayo:
1. Embonini yezokuvikela, ezempi, neye-aerospace, isetshenziswa ekuxhumaneni nomkhumbi ohamba ngaphansi komkhumbi ongaphansi kwamanzi, amasistimu wokulingisa umsindo wezinhlelo zokuhlonza/zokuthola, izindiza, izimoto ezihamba phansi, nezikhali;
2. Embonini ye-elekthronikhi kanye nezimboni zobuchwepheshe zokulawula okuzenzakalelayo ezinembayo, amadrayivu amancane okufuduka akhiqizwa kusetshenziswa i-GMM angasetshenziselwa amarobhothi, ukwenziwa kwemishini okunembe kakhulu kwezinsimbi ezihlukahlukene zokunemba, namadrayivu ediski optical;
3. Imboni yesayensi yasolwandle kanye nobunjiniyela be-offshore, okokusebenza kocwaningo lokusatshalaliswa kolwandle, indawo engaphansi kwamanzi, ukubikezela kokuzamazama komhlaba, kanye namasistimu e-sonar anamandla aphansi okudlulisa nokwamukela amasignali e-acoustic;
4. Izimboni zemishini, izindwangu, nezimboni zezimoto, ezingasetshenziselwa amasistimu amabhuleki azenzakalelayo, amasistimu omjovo kaphethiloli/umjovo, kanye nemithombo yamandla emincane esebenza kahle kakhulu;
5. I-ultrasound yamandla aphezulu, i-petroleum kanye nezimboni zezokwelapha, ezisetshenziswa kumakhemikhali e-ultrasound, ubuchwepheshe bezokwelapha be-ultrasound, izinsiza zokuzwa, kanye nama-transducer anamandla amakhulu.
6. Ingasetshenziswa emikhakheni eminingi efana nemishini yokudlidliza, imishini yokwakha, imishini yokushisela, nomsindo wokwethembeka okuphezulu.
