Ubuhanga bwo gupima Ultrasonic
1.Ibikenewe kuri lithiumbaterielectrode gupima inshundura
Litiyumu ya batiri ya electrode igizwe na kolitori, igatwikiriye hejuru ya A na B. Uburinganire bwuburinganire bwa coater nicyo kintu nyamukuru kigenzura ibice bya electrode ya lithium, bigira ingaruka zikomeye kumutekano, imikorere nigiciro cya batiri ya lithium. Kubwibyo, haribisabwa cyane kubikoresho byo gupima mugihe cya batiri ya lithium.
Uburyo bwo kohereza imishwarara guhuraingubushobozi ntarengwa
Dacheng Precision niyambere iyobora sisitemu ya electrode yo gupima igisubizo. Hamwe nimyaka irenga 10 yubushakashatsi niterambere, ifite urukurikirane rwibikoresho byo gupima neza kandi bihamye cyane, nka X / β-ray yerekana ubwinshi bwikigereranyo cyikigereranyo, uburebure bwa lazeri, uburebure bwa CDM hamwe nubucucike bwa areal, hamwe nibindi, bifite ubushobozi bwo kugera kumurongo wa interineti ya lithium-ion ya batiri ya electrode yibanze, harimo nubunini bwuzuye, ubunini, ubunini bwikibanza.
Uretse ibyo, Dacheng Precision ikora kandi impinduka mu ikoranabuhanga ryipimisha ridasenya, kandi yashyize ahagaragara igipimo cy’ubucucike bwa super X-Ray gishingiye ku byuma byifashishwa bya semiconductor hamwe n’ibipimo by'uburebure bwa infragre bishingiye ku ihame ryo kwinjiza ibintu bitagaragara. Umubyimba wibikoresho kama urashobora gupimwa neza, kandi ubunyangamugayo nibyiza kuruta ibikoresho byatumijwe hanze.

Dacheng Precision yamye yiyemeje gukora ubushakashatsi no guteza imbere ikoranabuhanga rishya. Usibye ibisubizo byavuzwe haruguru bidasenya ibisubizo, binateza imbere tekinoroji yo gupima ultrasonic. Ugereranije nibindi bisubizo byubugenzuzi, gupima uburebure bwa ultrasonic bifite ibimenyetso bikurikira.
3.1 Ihame ryo gupima uburebure bwa Ultrasonic
Ubunini bwa Ultrasonic bupima ubunini bushingiye ku ihame ryuburyo bwa ultrasonic pulse. Iyo ultrasonic pulse yoherejwe na probe inyuze mubintu byapimwe kugirango igere kubintu bifatika, umuraba wa pulse ugaruka kuri probe. Ubunini bwikintu cyapimwe burashobora kugenwa no gupima neza igihe cyo gukwirakwiza ultrasonic.
H = 1/2 * (V * t)
Ibicuruzwa hafi ya byose bikozwe mubyuma, plastike, ibikoresho byinshi, ubukerarugendo, ikirahure, fibre yikirahure cyangwa reberi birashobora gupimwa murubu buryo, kandi birashobora gukoreshwa cyane muri peteroli, imiti, metallurgie, kubaka ubwato, indege, ikirere nizindi nzego.
3.2Aibyizaya ugupima uburebure bwa ltrasonic
Igisubizo gakondo gikoresha uburyo bwo kohereza imirasire kugirango bapime igiteranyo cyuzuye hanyuma bakoreshe gukuramo kugirango babare agaciro ka batiri ya litiro ya electrode net coating. Mugihe uburebure bwa ultrasonic bushobora gupima agaciro bitewe nuburyo butandukanye bwo gupima.
Umuhengeri wa ultrasonic ufite imbaraga zikomeye zo kwinjira bitewe nuburebure bwawo buke, kandi birakoreshwa mubikoresho byinshi.
② Ultrasonic sound beam irashobora kwibanda mucyerekezo cyihariye, kandi ikagenda mumurongo ugororotse unyuze hagati, hamwe nubuyobozi bwiza.
No Nta mpamvu yo guhangayikishwa n'ikibazo cy'umutekano kuko idafite imirasire.
Nubwo, nubwo gupima uburebure bwa ultrasonic bifite ibyiza nkibyo, ugereranije nubuhanga butandukanye bwo gupima umubyimba Dacheng Precision yamaze kuzana ku isoko, ikoreshwa ryikigereranyo cy’uburebure bwa ultrasonic gifite aho kigarukira ku buryo bukurikira.
3.3 Gukoresha imipaka yo gupima uburebure bwa ultrasonic
LUltrasonic transducer: transducer ya ultrasonic, ni ukuvuga probe ya ultrasonic probe yavuzwe haruguru, nigice cyingenzi cyibipimo bipima ultrasonic, ibasha kwanduza no kwakira imiraba. Ibipimo byingenzi byerekana inshuro zakazi nigihe cyo kumenya igihe cyo gupima uburebure. Kugeza ubu transducer yo mu rwego rwo hejuru iracyashingira ku bicuruzwa biva mu mahanga, igiciro cyacyo kikaba gihenze.
UnUburinganire bwibintu: nkuko byavuzwe mumahame shingiro, ultrasonic izagaruka inyuma kubintu bifatika. Ibitekerezo biterwa nimpinduka zitunguranye muri acoustic impedance, kandi uburinganire bwa acoustic impedance bugenwa nuburinganire bwibintu. Niba ibikoresho bigomba gupimwa bidahuye, ikimenyetso cya echo kizatanga urusaku rwinshi, bigira ingaruka kubisubizo.
③ Ubukonje: hejuru yubuso bwibintu byapimwe bizatera echo nkeya igaragara, cyangwa idashobora kwakira ibimenyetso bya echo;
EmUbushyuhe: ishingiro rya ultrasonic nuko ihindagurika ryimashini ryibice bito bikwirakwizwa muburyo bwumuraba, bidashobora gutandukanywa no guhuza ibice bito. Kugaragara kwa macroscopique yerekana ubushyuhe bwumuriro wibice ubwabyo ni ubushyuhe, kandi ubushyuhe bwumuriro bizagira ingaruka kumikoranire hagati yibice bito. Ubushyuhe rero bugira ingaruka zikomeye kubisubizo byo gupima.
Kubipimo bya ultrasonic bisanzwe bipima bishingiye ku ihame rya pulse echo, ubushyuhe bwamaboko yabantu buzagira ingaruka kubushyuhe bwa probe, bityo biganisha ku kugabanuka kwa zeru ya gipimo.
Ability Guhagarara: ijwi ryijwi ni ihindagurika ryimashini yibice bito muburyo bwo gukwirakwiza imiraba. Irashobora kwivanga hanze, kandi ibimenyetso byakusanyirijwe ntabwo bihamye.
MediumGuhuza uburyo: ultrasonic izahurira mu kirere, mugihe ishobora gukwirakwizwa neza mumazi n'ibikomeye. Kugirango twakire neza ibimenyetso bya echo, uburyo bwo guhuza amazi busanzwe bwongerwaho hagati ya ultrasonic probe nikintu cyapimwe, kikaba kidafasha mugutezimbere gahunda yo kugenzura byikora.
Ibindi bintu, nka ultrasonic phase ihindagurika cyangwa igoreka, kugabanuka, taper cyangwa eccentricité yubuso bwikintu cyapimwe bizagira ingaruka kubipimo byo gupima.
Birashobora kugaragara ko gupima uburebure bwa ultrasonic bifite ibyiza byinshi. Ariko, kuri ubu ntishobora kugereranwa nubundi buryo bwo gupima ubunini kubera aho bugarukira.
3.4Ultrasonic uburebure bwo gupima ubushakashatsi iterambereByaDachengPgusubiramo
Dacheng Precision yamye yiyemeje gukora ubushakashatsi niterambere. Mu rwego rwo gupima uburebure bwa ultrasonic, nabwo bwateye imbere. Bimwe mubisubizo byubushakashatsi byerekanwe kuburyo bukurikira.
3.4.1 Imiterere yubushakashatsi
Anode yashizwe kumurongo wakazi, kandi ubwayo yateje imbere cyane-ultrasonic probe ikoreshwa mugupima-ingingo.
Igishushanyo 2 gupima uburebure bwa Ultrasonic
3.4.2 Amakuru yubushakashatsi
Amakuru yubushakashatsi atangwa muburyo bwa A-scan na B-scan. Muri A-scan, X-axis, byerekana igihe cyo kohereza ultrasonic na Y-axis yerekana ubukana bwumurongo. B-scan yerekana ishusho-ibiri yerekana ishusho igereranya nicyerekezo cyogukwirakwiza umuvuduko wijwi hamwe na perpendicular kubuso bwapimwe bwikintu kiri munsi yikizamini.
Uhereye kuri A-scan, urashobora kubona ko amplitude yumubyigano wa pulse yagarutse ihuriro rya grafite na fayili y'umuringa iri hejuru cyane ugereranije nizindi miyoboro. Umubyimba wububiko bwa grafite urashobora kuboneka mukubara acoustic-inzira ya ultrasonic wave mumashusho ya grafite.
Inshuro 5 zose zamakuru zageragejwe kumyanya ibiri, Point1 na Point2, naho acoustic-inzira ya grafite kuri Point1 yari 0.0340, naho acoustic-inzira ya grafite kuri Point2 yari 0.0300 twe, hamwe nibisobanuro byisubiramo.
Igishushanyo 3 A-scan ikimenyetso
Igishushanyo 4 B-scan ishusho
Igishushanyo.1 X = 450, YZ indege B-scan ishusho
Ingingo1 X = 450 Y = 110

4. Summaryya lithiumbaterielectrode tekinoroji yo gupima net
Ubuhanga bwo gupima Ultrasonic, nkimwe muburyo bwingenzi bwikoranabuhanga ryipimisha ridasenya, ritanga uburyo bwiza kandi rusange bwo gusuzuma microstructure hamwe nubukanishi bwibikoresho bikomeye, no kumenya micro- na macro-guhagarika. Imbere yo gukenera gupimwa kumurongo wapimye net net ya litiro ya batiri ya electrode, uburyo bwo kohereza imirasire buracyafite inyungu nini kurubu kubera ibiranga ultrasonic ubwayo nibibazo bya tekiniki bigomba gukemurwa.
Dacheng Precision, nkinzobere mu gupima electrode, izakomeza gukora ubushakashatsi bwimbitse no guteza imbere ikoranabuhanga rishya ririmo tekinoroji yo gupima uburebure bwa ultrasonic, gutanga umusanzu mu iterambere no gutera imbere kwipimisha ridasenya!
