Izinto ezinqabileyo zomhlaba zemagnetostrictive, enye yezona zinto zithembisayo kuphuhliso

Izinto ezinqabileyo zemagnetostrictive zomhlaba

Xa into yenziwe nguzibuthe kummandla wemagnethi, iya kuba nde okanye ibe mfutshane kwicala lemagneti, ebizwa ngokuba yimagnetostriction.Ixabiso le-magnetostrictive lezinto eziqhelekileyo ze-magnetostrictive yi-10-6-10-5 kuphela, encinci kakhulu, ngoko ke amasimi esicelo nawo anqongophele.Nangona kunjalo, kwiminyaka yakutshanje, kuye kwafunyaniswa ukuba kukho izinto ze-alloy kwi-alloys yomhlaba enqabileyo engama-102-103 amaxesha amakhulu kune-magnetostriction yasekuqaleni.Abantu babhekisa kwesi sixhobo sinemagnetostriction enkulu njengezinto ezinqabileyo zomhlaba ezinkulu zemagnetostrictive.

Izinto ezinqabileyo zomhlaba zemagnetostrictive luhlobo olutsha lwezinto ezisebenzayo ezisanda kuphuhliswa ngamazwe angaphandle ngasekupheleni kweminyaka yoo-1980.Ikakhulu ibhekisa kwi-iron yomhlaba enqabileyo esekwe kwi-intermetallic compounds.Olu hlobo lwemathiriyeli lunexabiso elikhulu ngakumbi le-magnetostrictive kunentsimbi, i-nickel, kunye nezinye izinto.Kwiminyaka yakutshanje, ngokucuthwa okuqhubekayo kweendleko zezinto ezinqabileyo zomhlaba ezinkulu zemagnetostrictive (REGMM) kunye nokwandiswa okuqhubekayo kweendawo zesicelo, imfuno yentengiso iye yomelela ngakumbi.

Uphuhliso lweMathiriyeli yeMagnetostrictive eRare Earth

I-Beijing Iron kunye ne-Steel Research Institute yaqala uphando lwayo kwi-GMM yeteknoloji yokulungiselela kwangaphambili.Ngo-1991, yaba yeyokuqala e-China ukulungisa imivalo ye-GMM kwaye yafumana ipatent yesizwe.Emva koko, uphando olongezelelweyo kunye nesicelo senziwe kwi-low-frequency underwater acoustic transducers, i-fiber optic ukubonwa kwangoku, i-high-power ultrasonic welding transducers, njl. iitoni zaphuhliswa.Imathiriyeli ye-GMM ephuhliswe yiYunivesithi yaseBeijing yeSayensi nobuChwepheshe iye yavavanywa kwiiyunithi ezingama-20 ekhaya nakumazwe ngamazwe, ibe neziphumo ezihle.Inkampani yaseLanzhou Tianxing ikwaphuhlise umgca wemveliso kunye nomthamo wonyaka wemveliso yeetoni, kwaye wenze impumelelo ebalulekileyo kuphuhliso kunye nokusetyenziswa kwezixhobo ze-GMM.

Nangona uphando lwaseTshayina malunga ne-GMM luqale kungekudalanga, lusekwinqanaba lokuqala loshishino kunye nophuhliso lwezicelo.Okwangoku, i-China ayifuni kuphela ukwenza impumelelo kwi-teknoloji yokuvelisa i-GMM, izixhobo zokuvelisa, kunye neendleko zokuvelisa, kodwa kufuneka ifake amandla ekuphuhliseni izixhobo zesicelo sezinto eziphathekayo.Amazwe angaphandle afaka ukubaluleka okukhulu ekudityanisweni kwezinto ezisebenzayo, amacandelo, kunye nezixhobo zokusebenza.Izinto ze-ETREMA e-United States ngowona mzekelo uqhelekileyo wokudityaniswa kwezinto kunye nesicelo sophando lwesixhobo kunye nokuthengisa.Ukusetyenziswa kwe-GMM kubandakanya imimandla emininzi, kwaye abangaphakathi kwishishini kunye noosomashishini kufuneka babe nombono weqhinga, ukubona kwangaphambili, kunye nokuqonda okwaneleyo kophuhliso kunye nokusetyenziswa kwezinto ezisebenzayo kunye nethemba lokusetyenziswa ngokubanzi kwinkulungwane yama-21.Bamele babeke iliso elibukhali kwiintsingiselo zophuhliso kulo mmandla, bakhawulezise inkqubo yayo yoshishino, kwaye bakhuthaze kwaye baxhase uphuhliso kunye nokusetyenziswa kwezixhobo zesicelo se-GMM.

Izinto eziluncedo kwiZixhobo zeMagnetostrictive ezinqabileyo zomhlaba

I-GMM inezinga eliphezulu lokuguqulwa kwamandla oomatshini kunye nombane, ukuxinana kwamandla aphezulu, isantya esiphezulu sokuphendula, ukuthembeka okulungileyo, kunye nemowudi yokuqhuba elula kwiqondo lokushisa.Zizo ezi zibonelelo zokusebenza ezikhokelele kutshintsho lwenguqu kwiinkqubo zolwazi lwe-elektroniki zemveli, iinkqubo zokuva, iinkqubo zokungcangcazela, njalo njalo.

Ukusetyenziswa kweMathiriyeli yeMagnetostrictive eRare Earth

Kwinkulungwane entsha yetekhnoloji ephuhla ngokukhawuleza, ngaphezu kwe-1000 izixhobo ze-GMM ziye zaziswa.Ezona ndawo zisetyenziswayo kwiGMM ziquka oku kulandelayo:

1. Kwimizi-mveliso yezokhuselo, yomkhosi, kunye ne-aerospace, isetyenziswa kwiinqanawa zonxibelelwano ezihamba ngaphantsi kwamanzi, iisistim zokulinganisa izandi zokubona/ukubona, iinqwelo-moya, izithuthi eziphantsi komhlaba kunye nezixhobo;

2. Kwishishini le-electronics kunye ne-high-precision automative control industries, i-micro displacement drives eyenziwe kusetyenziswa i-GMM ingasetyenziselwa iirobhothi, i-ultra precision machining yezixhobo ezichanekileyo ezichanekileyo, kunye ne-optical disk drives;

3. Inzululwazi yaselwandle kunye neshishini lobunjineli laphesheya kolwandle, izixhobo zovavanyo zokusasazwa kolwandle ngoku, inkcazo-mphandle yamanzi aphantsi kwamanzi, uqikelelo lwenyikima, kunye neenkqubo zesonar zamandla asezantsi okuhambisa nokwamkela imiqondiso ye-acoustic;

4. Oomatshini, iimpahla ezilukiweyo, kunye nemizi-mveliso yeemoto, ezinokuthi zisetyenziselwe iinkqubo zokuqhobosha ezizenzekelayo, iisistim zamafutha/isitofu sokutofa, kunye nemithombo yamandla emincinci esebenza kakhulu;

5. I-ultrasound yamandla aphezulu, i-petroleum kunye namashishini ezonyango, asetyenziswa kwi-ultrasound chemistry, i-ultrasound technology technology, izixhobo zokuva, kunye ne-high-power transducers.

6. Ingasetyenziswa kwiinkalo ezininzi ezifana noomatshini bokungcangcazela, oomatshini bokwakha, izixhobo zokuwelda, kunye nokuthembeka okuphezulu komsindo.
