Ultrasonic ana mānoanoa 'enehana
1. Pono no lithiumpākaukauelectrode ana uhi upena
Hoʻokumu ʻia ka electrode pākaukau Lithium me ka ʻohi, ka uhi ʻana ma ka ʻili A a me B. ʻO ka mānoanoa like ʻole o ka uhi ʻana ʻo ia ke kumu hoʻokele mana o ka electrode pākaukau lithium, he hopena koʻikoʻi i ka palekana, ka hana a me ke kumukūʻai o ka pā lithium. No laila, aia nā koi kiʻekiʻe no ka hoʻāʻo ʻana i nā mea hana i ka wā o ke kaʻina hana pākaukau lithium.
2.X-ray kaʻina hoʻoili huianaka palena palena
ʻO Dacheng Precision kahi alakaʻi alakaʻi honua systematic electrode solution solution provider. Me ka ʻoi aku o 10 mau makahiki o ka noiʻi a me ka hoʻomohala ʻana, loaʻa iā ia kahi ʻano o nā mea ana kiʻekiʻe kiʻekiʻe a me ka paʻa kiʻekiʻe, e like me ka X / β-ray areal density gauge, laser thickness gauge, CDM mānoanoa a me ka areal density integrated gauge, etc.
Ma waho aʻe, Dacheng Precision ke lawe nei hoʻi i nā loli i ka ʻenehana hoʻāʻo ʻole luku, a ua hoʻokuʻu ʻo Super X-Ray areal density ana ma muli o nā mea ʻike semiconductor paʻa a me nā ana mānoanoa infrared e pili ana i ka loiloi infrared spectral absorption. Hiki ke ana pololei ʻia ka mānoanoa o nā mea kūlohelohe, a ʻoi aku ka maikaʻi o ka pololei ma mua o nā mea i lawe ʻia mai.

Ua kūpaʻa mau ʻo Dacheng Precision i ka noiʻi a me ka hoʻomohala ʻana i nā ʻenehana hou. Ma waho aʻe o ka luna hoʻāʻo non-destructive ho'āʻo hāʻina, ka mea, e hoʻomōhala ana ultrasonic mānoanoa ana 'enehana. Hoʻohālikelike ʻia me nā ʻano hoʻonā nānā ʻē aʻe, ʻo ke ana ʻana o ka mānoanoa ultrasonic nā hiʻohiʻona aʻe.
3.1 Ana kumu mānoanoa ultrasonic
Kani ultrasonic mānoanoa ana ana i ka mānoanoa ma muli o ke kumu o kani ultrasonic pulse noonoo ala. Ke hele ka pulupulu kani ultrasonic i hoʻokuʻu ʻia e ka ʻimi noiʻi i ka mea i ana ʻia e hōʻea i nā mea pili waiwai, ʻike ʻia ka nalu pulse i ka probe. Hiki ke hoʻoholo ʻia ka mānoanoa o ka mea i ana ʻia ma ke ana pololei ʻana i ka manawa hoʻolaha ultrasonic.
H=1/2*(V*t)
Aneane hiki ke ana i na hua metala, plastic, composite material, ceramics, glass, glass fiber or rubber ma keia ano, a hiki ke hoohana nui ia i ka aila, kemika, metallurgy, kapili moku, aviation, aerospace a me na aina e ae.
3.2Anā mea maikaʻio uana mānoanoa ltrasonic
Hoʻohana ka hoʻonā kuʻuna i ke ala hoʻoili ray e ana i ka nui o ka uhi ʻana a laila hoʻohana i ka unuhi ʻana e helu i ka waiwai o ka nui o ka nui o ka uhi ʻana o ka pā uila lithium. Oiai kani ultrasonic mānoanoa ana hiki ke ana pololei i ka waiwai ma muli o ke ana okoa kumu.
①Ultrasonic hawewe he ikaika hiki ke komo ma muli o kona pōkole hawewe lōʻihi, a ua pili i ka laulā huahelu.
② Hiki ke hoʻopaʻa ʻia ke kani kani kani kani ultrasonic ma kahi kuhikuhi kikoʻī, a hele ia ma kahi laina pololei ma waena o ke kikowaena, me kahi kuhikuhi maikaʻi.
③ ʻAʻohe pono e hopohopo e pili ana i ka pilikia palekana no ka mea ʻaʻohe ona radiation.
Eia nō naʻe, ʻoiai ʻo ke ana ʻana o ka mānoanoa kani ultrasonic i nā mea maikaʻi, ke hoʻohālikelike ʻia me nā ʻenehana ana i ka mānoanoa i lawe ʻia e Dacheng Precision i ka mākeke, ʻo ka noi ʻana o ke ana mānoanoa kani ultrasonic kekahi mau palena e like me kēia.
3.3 Nā palena noi o ke ana mānoanoa kani ultrasonic
①Ultrasonic transducer: ultrasonic transducer, ʻo ia hoʻi, ka ʻimi ultrasonic i ʻōlelo ʻia ma luna, ʻo ia ka mea nui o nā ana hoʻāʻo ultrasonic, hiki ke hoʻouna a loaʻa i nā nalu pulse. ʻO kāna mau hōʻailona koʻikoʻi o ka hana pinepine a me ka pololei o ka manawa e hoʻoholo ai i ka pololei o ke ana mānoanoa. Ke hilinaʻi nei ka transducer ultrasonic kiʻekiʻe i kēia manawa i nā lawe ʻia mai nā ʻāina ʻē, nona ke kumukūʻai.
②Material uniformity: e like me ka mea i ʻōlelo ʻia ma nā kumu kumu, e ʻike hou ʻia ka ultrasonic ma nā mea pili. Hoʻokumu ʻia ka noʻonoʻo e nā loli koke i ka impedance acoustic, a ʻo ka kūlike o ka impedance acoustic e hoʻoholo ʻia e ka mea like ʻole. Inā ʻaʻole like ka mea e ana ʻia, e hoʻopuka ka leo leo i ka leo nui, e pili ana i nā hopena ana.
③ Ka 'o'ole'a: 'o ka 'o'ole'a o ka 'ili o ka mea i ana 'ia e ho'oha'aha'a 'ia ka leo, a 'a'ole hiki ke loa'a ka hō'ailona echo;
④Temperature: ʻo ke ʻano o ka ultrasonic ke hoʻolaha ʻia ka haʻalulu mechanical o nā ʻāpana liʻiliʻi ma ke ʻano o nā nalu, ʻaʻole hiki ke hoʻokaʻawale ʻia mai ka pilina o nā ʻāpana waena. ʻO ka hiʻohiʻona macroscopic o ka neʻe wela o nā ʻāpana liʻiliʻi iā lākou iho he wela, a e hoʻopili maoli ka neʻe wela i ka pilina ma waena o nā ʻāpana waena. No laila he hopena nui ka mahana i nā hopena ana.
No ka ana mānoanoa kani ultrasonic mānoanoa ma muli o ka pulse echo loina, kanaka lima lima e pili i ka probe wela, pela e alakai ana i ka nee ana o ka helu helu o ka ana.
⑤Stability: ʻo ka hawewe kani ka haʻalulu mechanical o nā ʻāpana waena ma ke ʻano o ka hoʻolaha ʻana o ka nalu. Hiki ke hoʻopilikia i waho, a ʻaʻole paʻa ka hōʻailona hōʻiliʻili.
⑥Mea hoʻohui: e hoʻemi ʻia ke kani ultrasonic i ka lewa, ʻoiai hiki ke hoʻolaha maikaʻi ʻia i nā wai a me nā paʻa. I mea e loaʻa maikaʻi ai ka hōʻailona echo, hoʻohui pinepine ʻia kahi mea hoʻohui wai ma waena o ka ultrasonic probe a me nā mea i ana ʻia, ʻaʻole kūpono i ka hoʻomohala ʻana i ka polokalamu nānā ʻokoʻa ma ka laina.
ʻO nā mea ʻē aʻe, e like me ka hoʻohuli ʻana a i ʻole ka distortion, ka curvature, taper a i ʻole eccentricity o ka ʻili o ka mea i ana ʻia e hoʻololi i nā hopena ana.
Hiki ke ʻike ʻia he nui nā pono o ke ana mānoanoa ultrasonic. Eia nō naʻe, ʻaʻole hiki ke hoʻohālikelike ʻia me nā ʻano ana mānoanoa ʻē aʻe ma muli o kona mau palena.
3.4Ultrasonic mānoanoa ana holomua noiʻi holomuaoDachengPhoʻoponopono
Ua paʻa mau ʻo Dacheng Precision i ka noiʻi a me ka hoʻomohala ʻana. Ma ke kahua o ke ana mānoanoa kani ultrasonic, ua hana i kekahi holomua. Hōʻike ʻia kekahi o nā hopena noiʻi penei.
3.4.1 Nā kūlana hoʻokolohua
Hoʻopaʻa ʻia ka anode ma ka papa hana, a hoʻohana ʻia ka ʻimi kani ultrasonic kiʻekiʻe i kūkulu ʻia no ke ana paʻa.
Kiʻi 2 Ana mānoanoa ultrasonic
3.4.2 ʻIkepili hoʻokolohua
Hōʻike ʻia nā ʻikepili hoʻokolohua ma ke ʻano o A-scan a me B-scan. Ma ka A-scan, X-axis, e hōʻike ana i ka manawa hoʻouna kani ultrasonic a ʻo Y-axis e hōʻike ana i ka ikaika o ka nalu i ʻike ʻia. Hōʻike ka B-scan i ke kiʻi ʻelua ʻāpana o ka ʻaoʻao e like me ke kuhikuhi o ka hoʻolaha ʻana o ka wikiwiki o ke kani a kū pololei i ka ʻili o ka mea i hoʻāʻo ʻia.
Mai ka A-scan, hiki ke ʻike ʻia ʻoi aku ka kiʻekiʻe o ka amplitude o ka hawewe pulse i ka hui ʻana o ka graphite a me ka foil keleawe ma mua o nā hawewe ʻē aʻe. Hiki ke loaʻa ka mānoanoa o ka uhi graphite ma ka helu ʻana i ke ala acoustic o ka hawewe kani ultrasonic ma ka graphite medium.
Ua hoʻāʻo ʻia ka huina o 5 mau manawa o ka ʻikepili ma nā kūlana ʻelua, Point1 a me Point2, a ʻo ke ala acoustic o ka graphite ma Point1 ʻo 0.0340 mākou, a ʻo ke ala acoustic o ka graphite ma Point2 he 0.0300 mākou, me kahi kiʻekiʻe repeatability precision.

4. Summaryo lithiumpākaukauelectrode ʻenehana ana ka uhi ʻupena
Kani ultrasonic ho'āʻo 'enehana, e like me kekahi o ka mea nui o ka non-destructive ho'āʻo 'enehana, e hoʻolako i ka pono a me ke ao holoʻokoʻa hana no ka loiloi 'ana i ka microstructure a me ka mechanical waiwai o paʻa mea, a me ka ike ana i ko lakou micro- a me macro-discontinuities. Ke alo nei i ke koi ʻana no ke ana ʻana ma ka laina o ka nui o ka uhi ʻana o ka pā uila lithium electrode, ʻoi aku ka maikaʻi o ke ʻano o ka ray transmission i kēia manawa ma muli o nā ʻano o ka ultrasonic ponoʻī a me nā pilikia ʻenehana e hoʻoponopono ʻia.
ʻO Dacheng Precision, e like me ka mea akamai i ke ana electrode, e hoʻomau i ka hoʻokō ʻana i ka noiʻi hohonu a me ka hoʻomohala ʻana i nā ʻenehana hou e pili ana i ka ʻenehana ana i ka mānoanoa kani ultrasonic, e hāʻawi i ka hāʻawi ʻana i ka hoʻomohala ʻana a me nā breakthroughs o ka hoʻāʻo ʻole luku!
