Ultrasonic ukobvu kuyerwa tekinoroji
1.Needs for lithiumbhatirielectrode net coating measure
Lithium bhatiri electrode inoumbwa nemuunganidzi, inoputira pamusoro peA uye B. Ukobvu kufanana kwekuputira ndiyo core control parameter ye lithium battery electrode, iyo ine simba rinokosha pakuchengetedza, kushanda uye mari ye lithium battery. Naizvozvo, pane zvakakwirira zvinodikanwa zvekuyedza michina panguva yelithium bhatiri yekugadzira maitiro.
2.X-ray nzira yekufambisa kusanganaingthe limit capacity
Dacheng Precision inotungamira pasi rese yakarongeka electrode kuyerwa kwemhinduro mupi. Neanopfuura makore gumi ekutsvagisa nekusimudzira, ine nhevedzano yemhando yepamusoro-chaiyo uye yakakwirira-kugadzikana yekuyera michina, yakadai seX/β-ray aral density gauge, laser ukobvu gauge, CDM ukobvu uye real density integrated gauge, zvichingodaro, izvo zvinokwanisa kuwana online kutarisisa kwelithium-ion bhatiri electrode's core coating, ukobvu hwenzvimbo, kuonda kwenzvimbo, kuonda kwenzvimbo. density.
Kunze kwezvo, Dacheng Precision iri kuitawo shanduko mune isinga paradza tekinoroji yekuyedza, uye yatangisa Super X-Ray aal density geji yakavakirwa pane yakasimba-state semiconductor detectors uye infrared ukobvu geji yakavakirwa infrared spectral absorption musimboti. Hukobvu hwezvinhu zveoga hunogona kuyerwa nemazvo, uye huchokwadi huri nani pane midziyo inounzwa kunze kwenyika.

Dacheng Precision yagara yakazvipira kutsvaga nekuvandudza matekinoroji. Pamusoro peiyo iri pamusoro isingaparadze mhinduro dzekuyedza, iri kuvandudza tekinoroji yekuyera tekinoroji. Kuenzaniswa nedzimwe mhinduro dzekuongorora, ultrasonic ukobvu kuyerwa kune zvinotevera maitiro.
3.1 Ultrasonic ukobvu kuyerwa musimboti
Ultrasonic ukobvu gauge inoyera ukobvu zvichibva pane musimboti we ultrasonic pulse reflection nzira. Kana iyo ultrasonic pulse inoburitswa neprobe ichipfuura nepakati pechinhu chakayerwa kuti isvike kune zvinhu interfaces, iyo pulse wave inoratidzwa ichidzokera kune probe. Ukobvu hwechinhu chakayerwa hunogona kutsanangurwa nekuyera nemazvo iyo ultrasonic propagation nguva.
H=1/2*(V*t)
Zvinenge zvese zvakagadzirwa nesimbi, mapurasitiki, zvinhu zvinoumbwa, ceramics, girazi, girazi faibha kana rabha zvinogona kuyerwa nenzira iyi, uye inogona kushandiswa zvakanyanya mupetroleum, makemikari, metallurgy, kuvaka ngarava, ndege, aerospace uye mamwe minda.
3.2Azvakanakirazveultrasonic ukobvu kuyerwa
Iyo yechinyakare mhinduro inotora ray yekufambisa nzira kuyera iyo yakazara coating huwandu uye wobva washandisa kubvisa kuverenga kukosha kwe lithium bhatiri electrode net coating huwandu. Nepo ultrasonic ukobvu geji inogona kuyera zvakananga kukosha nekuda kweiyo yakasiyana kuyerwa musimboti.
①Ultrasonic wave ine simba rekupinda nekuda kwekupfupika kwayo kwewavelength, uye inoshanda kune dzakasiyana siyana zvinhu.
② Ultrasonic sound beam inogona kuiswa mune imwe nzira, uye inofamba mumutsara wakatwasuka kuburikidza nepakati, ine kutungamira kwakanaka.
③ Hapana chikonzero chekunetseka nezvenyaya yekuchengetedza nekuti haina radiation.
Nekudaro, kunyangwe ichokwadi chekuti ultrasonic ukobvu kuyerwa kune zvakanakira zvakadaro, zvichienzaniswa neakati wandei matekinoroji ekuyera ayo Dacheng Precision yatounza kumusika, kushandiswa kweiyo ultrasonic ukobvu kuyerwa kune zvimwe zvipimo sezvinotevera.
3.3 Kutemerwa kwekushandisa kwe ultrasonic ukobvu kuyerwa
①Ultrasonic transducer: ultrasonic transducer, kureva, iyo ultrasonic probe yataurwa pamusoro, ndiyo yakakosha chikamu che ultrasonic test geji, inokwanisa kuendesa uye kugamuchira mafungu emhepo. Zviratidzo zvaro zvepakati zvekushanda frequency uye nguva yekurongeka inosarudza kurongeka kwekuyera kwekobvu. Ikozvino yakakwirira-yekupedzisira ultrasonic transducer ichiri kutsamira pane inotengeswa kubva kunze kwenyika, iyo mutengo wayo unodhura.
②Material kufanana: sezvakataurwa mumisimboti yekutanga, ultrasonic inozoratidzwa kumashure pane zvekushandisa interfaces. Iko kufungidzira kunokonzerwa nekukasira kushanduka mune acoustic impedance, uye kufanana kweiyo acoustic impedance inotarirwa nekufanana kwezvinhu. Kana izvo zvinoyerwa zvisina kufanana, iyo echo chiratidzo inoburitsa ruzha rwakawanda, ichikanganisa kuyerwa kwemhedzisiro.
③ Hushasha: kushata kwepamusoro pechinhu chakayerwa kunokonzeresa maungira akaderera, kana kutotadza kugashira maungira;
④Tembiricha: the essence of ultrasonic is that the mechanical vibration of medium particles inoparadzirwa nenzira yemafungu, iyo isingagoni kupatsanurwa kubva pakubatana kwepakati zvidimbu. Iyo macroscopic kuratidzwa kwekupisa kwekufamba kwepakati masisitimu iwo tembiricha, uye kupisa kwekufamba kunozokanganisa kudyidzana pakati pepakati zvidimbu. Saka tembiricha ine simba guru pamibairo yekuyera.
Kune yakajairwa ultrasonic ukobvu kuyerwa kwakavakirwa pa pulse echo musimboti, tembiricha yeruoko rwevanhu inokanganisa tembiricha yeprobe, zvichitungamira kune kukukurwa kwe zero point yegeji.
⑤ Kugadzikana: iyo ruzha wave ndiyo mechanical vibration yepakati zvimedu nenzira yekuparadzira wave. Inokonzerwa nekupindira kwekunze, uye chiratidzo chakaunganidzwa hachina kugadzikana.
⑥Kubatanidza svikiro: ultrasonic inodzikamisa mumhepo, nepo inogona kunyatso kuparadzirwa muzvinwiwa uye zvakaonda. Kuti ugamuchire zvirinani iyo echo chiratidzo, mvura yekubatanidza svikiro inowanzowedzerwa pakati pe ultrasonic probe uye yakayerwa chinhu, izvo zvisingaenderane nekuvandudzwa kweon-line otomatiki yekuongorora chirongwa.
Zvimwe zvinhu, senge ultrasonic phase reversal kana kukanganisa, iyo curvature, taper kana eccentricity yepamusoro pechinhu chakayerwa chinozopesvedzera mhedzisiro yekuyera.
Zvinogona kuoneka kuti ultrasonic ukobvu kuyerwa kune akawanda mabhenefiti. Nekudaro, parizvino haigone kuenzaniswa nedzimwe nzira dzekuyera ukobvu nekuda kwekugumira kwayo.

Dacheng Precision yagara yakazvipira kutsvaga nekusimudzira. Mumunda weiyo ultrasonic ukobvu kuyerwa, yakaitawo kumwe kufambira mberi. Mimwe yemigumisiro yekutsvaga inoratidzwa sezvinotevera.
3.4.1 Mamiriro ekuedza
Iyo anode inogadziriswa patafura yekushanda, uye iyo yakagadziridzwa yakakwira-frequency ultrasonic probe inoshandiswa kune yakatarwa-point kuyerwa.

3.4.2 Data yekuedza
Iyo data yekuyedza inoratidzwa muchimiro cheA-scan uye B-scan. MuA-scan, X-axis, inomiririra iyo ultrasonic transmission nguva uye Y-axis inomiririra inoratidzwa wave wave. B-scan inotaridza mativi maviri-dimensional mufananidzo wembiri inofambirana negwara reinzwi velocity propagation uye perpendicular kune yakayerwa pamusoro pechinhu chiri kuedzwa.
Kubva paA-scan, zvinogona kuonekwa kuti amplitude yekudzoka pulse wave panosangana graphite nemhangura foil yakakwirira zvikuru kupfuura yemamwe mafungu. Ukobvu hwekufukidzira kwegraphite hunogona kuwanikwa nekuverenga iyo acoustic-nzira ye ultrasonic wave mune graphite medium.
Yakakwana ye5 nguva yedata yakaedzwa panzvimbo mbiri, Point1 uye Point2, uye acoustic-nzira yegraphite paPoint1 yaive 0.0340 isu, uye acoustic-nzira yegraphite paPoint2 yaive 0.0300 isu, ine yakakwira kudzokorora chaiko.

4. Summaryzvelithiumbhatirielectrode net coating measurement technology
Ultrasonic yekuongorora tekinoroji, seimwe yenzira dzakakosha dzekusaparadza tekinoroji yekuyedza, inopa inoshanda uye yepasirese nzira yekuongorora iyo microstructure uye michina zvimiro zvezvinhu zvakasimba, uye kuona yavo micro- uye macro-discontinuities. Takatarisana nekudiwa kwe-on-line otomatiki kuyerwa kweiyo net coating huwandu hwelithium bhatiri electrode, iyo ray transmission nzira ichine mukana wakakura parizvino nekuda kwehunhu hwe ultrasonic pachayo uye matambudziko ehunyanzvi anogadziriswa.
Dacheng Precision, senyanzvi mukuyera kweelectrode, icharamba ichiita tsvakiridzo yakadzama nekuvandudza matekinoroji anosanganisira ultrasonic ukobvu hwekuyera tekinoroji, ichipa mupiro mukusimudzira uye kubudirira kweyedzo isingaparadze!
