Cov ntsiab cai tseem ceeb ntawm ultrasonic vuam txheej txheem thiab tshuab ultrasonic welding
Lub hauv paus ntsiab lus ntawm ultrasonic vuam tau muab faib ua ob pawg: 1-Lub ntsiab lus vuam ntawm lub tshuab ultrasonic welding, 2-Lub ntsiab lus thov ntawm ultrasonic hauv kev ua cov yas, nrog rau cov kev txwv thiab kev kho ntawm ultrasonic vuam tshuab, thiab lwm yam, plaub qhov kev txiav txim siab dav dav ntawm ultrasonic vuam tshuab Kev paub cov ntsiab lus. Hauv qab no peb yuav piav qhia hauv qhov tob tob kev paub ntawm ultrasonic yas vuam tshuab:
Kev paub ultrasonic (1):
Txhawm rau kom tau txais qhov zoo tshaj plaws thiab rov ua dua ntawm fusion welding txoj kev, peb txoj kev tsim qauv tseem ceeb yuav tsum tau ua raws: (1) Ob qhov chaw sib txuas lus ua ntej yuav tsum tau me me txhawm rau txhawm rau siv lub zog xav tau thiab tsawg kawg ntawm tag nrho lub zog xav tau (piv txwv li sijhawm) kom tiav lub splicing.
(2) Lub vuam viav vias nyob ib puag ncig cov kab sib txuas sib txuas yuav tsum tau sib txig sib luag thiab nyob sib ze. Yog tias ua tau, qhov chaw hu yuav tsum nyob hauv tib lub dav hlau ntau li ntau tau, thiaj li hais tias lub zog hloov hluav taws xob tuaj yeem khaws cia kom xwm yeem.
(3) Nrhiav txoj hauv kev tsim nyog ntawm kev kho thiab ua kom haum, xws li; cov thom khwm, cov kauj ruam lossis tus nplaig-thiab-zawj ntawm cov yas.
Kev paub ultrasonic (ob):
Cov cawv ntawm cov khoom yas ntawm cov khoom ntawm ultrasonic vuam
Ultrasonic tsis pom tseeb hauv tshuab yas. Yas qhov chaw yuav ntau dua los yog tsawg dua nqus thiab attenuate ultrasonic zog, uas yuav muaj ib qho kev cuam tshuam rau cov txiaj ntsig ua ultrasonic. Plastics feem ntau muab faib ua cov khoom siv tsis-crystalline. Raws li cov tawv tawv, muaj cov roj hmab tawv thiab mos roj hmab. , Kuj tseem muaj qhov sib txawv ntawm cov qauv. Hauv layman' s cov lus, ultrasonic ua kev ua haujlwm ntawm cov yas nrog siab hardness thiab melting point yog qhov zoo dua li ntawm cov uas muaj cov tawv hardness thiab melting point. Yog li no, qhov no suav qhov teeb meem ntawm qhov kev ncua deb ntawm kev ua ultrasonic.
Kev paub ultrasonic (3):
Cawv ntawm kev ua cov xwm txheej ntawm cov ntu yas ntawm cov tshuab ultrasonic welding
Cov ntu yas dhau los ua cov txheej txheem sib txawv xws li kev txhaj tshuaj molding, extrusion lossis tshuab moulding, nrog rau kev ua cov txheej txheem sib txawv, yuav tsim cov yam uas muaj feem cuam tshuam rau ultrasonic welding. Muaj ob qho laj thawj loj:
(1) Qhov cuam tshuam ntawm txoj kev txhaj tshuaj molding cov txheej txheem:
Kev hloov kho ntawm cov tsis muaj ntawm cov txheej txheem txhaj tshuaj molding yuav ua rau muaj qhov tsis xws li hauv qab no:
1 Kev hnav khaub ncaws tsis zoo
2 deg puas
3 qhov hnyav hloov
4Qhov kev hloov pauv (shrinkage, khoov deformation)
Kev paub ultrasonic (plaub):
Qhov tsis zoo ntawm ultrasonic vuam tuaj yeem tau los ntawm kev tswj cov ntsiab lus hauv qab no:
(1) Kev them nyiaj yug hauv qab pwm
(2) Cov qauv ntawm cov khoom seem
(3) Hu rau qhov chaw ntawm vuam taub hau thiab cov yas
(4) Cov khoom siv vuam
(5) Qhov chaw thiab kev tsim ntawm vuam kab
(6) du txoj kev vuam
(7) Txoj haujlwm thiab nruj ntawm qaum thiab chaw qis
(8) Qhov loj ntawm vuam saum npoo
Kev paub ultrasonic (5)
Kev tsim qauv ntawm cov khoom siv yas. Cov kev txhaj tshuaj niaj hnub tuaj yeem ua tau zoo muab cov yas zoo meej rau vuam siv. Thaum peb txiav txim siab siv ultrasonic vuam thev naus laus zis kom ua tiav lub fusion, kev teeb tsa kev tsim qauv ntawm cov khoom siv yas yuav tsum xub xav txog cov ntsiab lus hauv qab no:
(1) Seb nws xav tau dejtight thiab airtight
(2) Seb nws puas tsim nyog rau vuam ua lub taub hau
(3) Qhov loj me me ntawm weld (uas yog, qhov yuav tsum tau muaj zog yuav tsum xav txog)
(4) Koj puas xav tau lub cev zoo meej
(5) Zam cov yas melting lossis dhau ntawm cov hluavtaws sib xyaw
Kev paub ultrasonic (6):
Vaum cov tsis xws luag: Cov av noo tsis xws luag feem ntau tsim nyob rau hauv tus txheej txheem ntawm kev ua cov streaks lossis xoob yas qhov chaw. Vaum qhov tsis xws luag ntxim nyiam lub zog siv thaum lub sijhawm vuam, ua rau dej pom ntawm lub chaw sib khi, thiab txuas ntxiv lub sijhawm thaum vuam. Yog li, cov khoom seem yas nrog cov av noo siab yuav tsum tau muab ziab ua ntej ua ntej vuam. kam nrog. Xws li polyoxymethylene thiab hais txog.
(1) Tso tus neeg sawv cev thiab impurities: Tso tus neeg sawv cev thiab impurities muaj qee yam ntxim rau ultrasonic welding. Txawm hais tias qhov hnyav thiab qhov tsis zoo ntawm cov txheej txheem txheej txheem tuaj yeem ua kom ploj mus thaum lub sij hawm ua ultrasonic, nws yuav tsum tau muab tshem tawm kom ntau li ntau tau thaum sib khi lossis lub zog siab yuav tsum ua. Muaj qee kis, nws yog ib qhov tsim nyog yuav tsum ntxuav cov ntu yas ua ntej.
(2) Txee lub neej: Tom qab cov khoom siv yas ua tiav los ntawm kev txhaj tshuaj molding, lawv feem ntau tso rau tsawg kawg 24 teev ua ntej vuam kom tshem tawm cov kev ntxhov siab thiab deformation ntawm qhov chaw yas lawv tus kheej. Cov ntu yas ua los ntawm amorphous yas los ntawm kev txhaj tshuaj molding tsis tau raws li qhov ua kom tiav no.
(3) Cov txheej txheem thim rov qab: lub zog ntawm kev siv rov qab siv cov khoom siv no kuj tsis tshua zoo, thiab kev yoog raws rau ultrasonic vuam kuj tsis zoo. Yog li ntawd, yog tias siv cov plastics tshiab rau siv, ntau qhov tsim qauv yuav tsum raug txiav txim siab raws li qhov tsim nyog.
