Daim ntawv thov ntawm lub tshuab ultrasonic welding thiab cov hauv paus ntsiab lus ntawm kiv vuam
Ultrasonic kev co hloov ua lub zog hluav taws xob rau hauv kev siv zog, thiab tom qab ntawd hloov lub zog mus rau qhov chaw tiv tauj ntawm cov khoom yas dhau ntawm lub tshuab raj, ua rau muaj kev sib txhuam muaj zog ntawm cov roj molecules thiab txhawb cov yaj thiab kev koom ua ke ntawm cov khoom. Txoj kev ua kom nrawm yog nrawm, huv, zoo nkauj thiab yig.
Kev siv vuam: cov khoom ua si khoom lag luam, ntawv sau kev lag luam, khoom siv hluav taws xob hauv tsev, kev lag luam khoom siv hluav taws xob, kev lag luam khoom noj khoom haus, kev lag luam sib txuas lus, kev lag luam thauj khoom, kev lag luam aerospace, thiab lwm yam.
Piv txwv li ntawm ultrasonic vuam:
Cov khoom siv niaj hnub: hmoov lub thawv, pleev daim iav, zuag, kaw lub nplhaib, thermos khob, ntim thawv airtight, lub raj mis ntim, lub raj xa dej ua ke, tuav
Lub raj mis hau, ntim khoom noj, tsheb teeb txawb, tsheb tso tsheb tso dej, thiab lwm yam.
Qho khoom ua si kev lag luam: txhua yam khoom ua si pob, ntawv sau, phom dej, khoom plig yas, khoom ua si suab paj nruag, ntau yam khoom ua si yas, thiab lwm yam.
Kev lag luam hluav taws xob: lub moos hluav taws xob, chav pa taws, lub tshuab nqus tsev, lub xov tooj, lub tshuab computer, kiv cua, roj teeb, thiab lwm yam.
Cov tsheb lag luam kev lag luam: lub teeb txawb, lub iav tig ntsia sab nraud, sab hauv nruab nrab, lub laub rov qab, ntau yam khoom siv yas, thiab lwm yam.
Kev lag luam hluav taws xob: Feem ntau tsim ntau yam khoom yas uas muaj feem xyuam xws li cov khoom siv fais fab, cov hloov kho, cov roj teeb hluav taws xob, thiab cov xov tooj ntawm tes. Kev lag luam hluav taws xob yog kev lag luam uas siv ntau lub tshuab ua haujlwm siv tshuab ultrasonic ntau dua.
Lub hauv paus ntsiab lus ntawm ultrasonic vuam tshuab kiv vuam
Nws yog tshwj xeeb tsim rau cov yas puag ncig cov khoom siv thermoplastic. Nyob rau hauv qhov kev txiav txim siab ntawm lub tshav kub uas tsim los ntawm kev sib txhuam ntawm qhov chaw ntawm cov yas, qhov chaw hu rau ntawm cov feem ntawm cov yas yuav yaj, thiab tom qab ntawd tau tsav los ntawm sab nraud lub siab, qhov seem ntawm sab thiab qis tau sib zog rau hauv lub cev sib xyaw.
Cov piv txwv ntawm kiv thiab yaj: rov qab osmosis lim, lub khob txias, lub tshuab nqus tsev, lub vias, carburetors, da dej tsis muaj dab, thermos fwj, Van De Street, thiab lwm yam.
Thaum ultrasonic vuam tawm hauv qhov nruab nrab, lawv yuav ua plaub yam hauv lub cev:
Neeg kho tshuab nyhuv
Cov neeg kho tshuab kev txiav txim ntawm ultrasound tuaj yeem txhawb cov kua emulsification, gel liquefaction thiab dispersion khoom. Thaum lub nthwv dej sawv tsim nyob rau hauv nruab nrab ultrasonic kua dej, cov hais tawm raug tshem tawm hauv cov kua dej ntawm lub node vim muaj cov khoom siv lub zog, ua rau lub sijhawm sib npaug nyob hauv qhov chaw. Thaum ultrasonic vuam tawm nyob rau hauv piezoelectric thiab magnetostrictive cov ntaub ntawv, induced polarization thiab induced magnetization vim qhov ua txhua yam ntawm ultrasonic tsis (saib Dielectric Physics thiab Magnetostriction).
Cavitation
Thaum ultrasonic vuam tsis ua kua, ntau tus npuas me me yog tsim tawm. Ib qho ntawm cov laj thawj yog tias qhov kev ntxhov siab hauv zos hauv cov kua ua rau lub siab tsis zoo. Qhov qis nyob rau hauv lub siab ua rau cov roj yaj kom yaj thiab lub zog ua kua, thiab tom qab ntawd khiav tawm ntawm cov kua los ua npuas me me. Lwm qhov laj thawj yog tias qhov muaj zog tensile siab" kua muag" cov kua dej rau hauv kab noj hniav, uas yog hu ua cavitation. Cov kab noj hniav puv nrog cov kua vapor lossis lwm cov roj yaj hauv cov kua, thiab tej zaum txawm tias yog lub tshuab nqus tsev. Cov npuas me me uas tsim los ntawm cavitation yuav dheev tsiv, loj hlob, lossis tawg nrog kev co ntawm ib puag ncig nruab nrab. Thaum lub npuas tawg, cov kua ib puag ncig dheev rhais rau hauv npuas, ua rau muaj qhov kub thiab txias, ua haujlwm siab thiab poob siab ntas. Sab hauv dissipation lub zog txuas nrog cavitation cov ntaub ntawv hluav taws xob tsub rau hauv cov npuas thiab tsim teeb ci thaum tawm mus. Lub tshuab ua kua ultrasonic kho feem ntau cuam tshuam nrog cavitation.
Thermal nyhuv
Vim lub siab thiab lub siab ntawm ultrasonic tsis, nws yuav tsim cov teebmeem thermal tom qab raug nqus los ntawm nruab nrab.
Tshuaj nyhuv
Cov nyhuv ntawm ultrasound tuaj yeem txhawb lossis leeb qee yam tshuaj lom neeg. Piv txwv, cov dej ntshiab ntshiab yuav tsim cov tshuaj hydrogen peroxide tom qab kho ultrasonic; cov dej ntim nitrogen yuav tsim cov nitrite tom qab kho ultrasonic; zas xim aqueous yuav hloov xim lossis thim tom qab kho ultrasonic. Cov tshwm sim no ib txwm nrog cavitation. Ntau yam tshuaj tuaj yeem raug hydrolyzed thiab polymerized los ntawm ultrasound. Cov nyhuv ntawm ultrasound rau ntawm photochemical thiab electrochemical cov txheej txheem kuj tseem pom tseeb. Tom qab kho ultrasonic, cov yam ntxwv ntawm cov amino acids thiab lwm yam organic hauv cov kua aqueous ploj, uas qhia kev haum dav dav, qhia tias cavitation hloov lub qauv tsim qauv.
