Muaj ntau yam cuam tshuam rau ultrasonic yas vuam nyhuv, thiab peb tab tom tham txog cov ntaub ntawv hauv kab lus no.
1. Cov khoom siv vuam ultrasonic sib txawv
Cov khoom siv vuam sib txawv cuam tshuam rau ultrasonic vuam zoo, ntxiv fiber ntau thiab lwm yam ntim tuaj yeem txhim kho cov khoom tawv tawv, uas yog qhov zoo rau kev sib kis ntawm ultrasonic, ntxiv cov fillers tuaj yeem txhim kho lub zog ntawm ultrasonic vuam pob qij txha nyob rau hauv cov txheej txheem tsim nyog.
2. Cov khoom siv ultrasonic vuam nto roughness
Kev ua kom lub ntsej muag roughness tsis tuaj yeem tsuas yog txo cov acoustic impedance, txhim kho lub zog ntws nrawm, tab sis kuj tuaj yeem txhim kho ultrasonic vuam zoo.Los ntawm kev siv cov khoom siv membrane nrog dov qauv ntawm qhov chaw, siab dua ultrasonic vuam zoo tuaj yeem tau txais, thiab nyob rau hauv txoj kev no, lub zog ntawm ultrasonic vuam sib koom ua ke tuaj yeem siab dua ob peb zaug dua li PP ib qho nrog du nto.
3. Ultrasonic vuam kab dav
Qhov nce ntawm ultrasonic vuam kab dav tuaj yeem txo lub zog ntawm ultrasonic welded sib koom;vim hais tias nrog kev nce ntawm ultrasonic welding kab dav, qhov kev ntxhov siab nyob rau ntawm ntug ntawm ultrasonic welded sib koom ua ke nce, cov microcracks tshwm ntawm ntug nce, thiab kev sib koom ua ke txo qis.
4. Kev cuam tshuam ntawm qhov kev ncua deb ntawm qhov chaw vuam mus rau qhov sib txuas ntawm vuam
Thaum qhov kev ncua deb ntawm ultrasonic vuam nto mus rau vuam sib koom ua ke mus txog qhov ib nrab-yoj tus nqi, lub zog ntawm ultrasonic vuam sib koom mus txog qhov siab tshaj plaws.Ultrasonic yoj mas propagates longitudinal-yoj nyob rau hauv plastics, thiab lub ncov tus nqi ntawm lub siab tshaj plaws longitudinal-yoj feem ntau tshwm nyob rau hauv ib nrab wavelength.Thaum nws nyob ze rau ib nrab wavelength, lub tshav kub lub zog ntawm ultrasonic yoj propagates mus rau lub ultrasonic vuam interface, thiab zoo ultrasonic vuam pob qij txha yuav tau.Qhov zoo ntawm ultrasonic vuam yog ncaj qha proportional rau lub elastic modulus, kev sib txhuam coefficient thiab thermal conductivity, thiab inversely proportional rau nws ceev, tshwj xeeb kub thiab melting point.
5.Lub melting point thiab nto kev sib txhuam ntawm cov khoom
Tus yuam sij ntawm ultrasonic vuam zoo yog muaj feem xyuam rau lub melting point thiab nto kev sib txhuam ntawm cov khoom.Qhov kev ntsuas no tsis zoo ib yam vim tias cov khoom sib txawv thiab qhov kub thiab txias, lawv qhov kev hloov pauv hauv cov txheej txheem ultrasonic vuam yuav ua rau qhov kub thiab txias, shear quab yuam thiab deformation ntawm ultrasonic vuam cheeb tsam, thiab tom qab ntawd ua mob rau qhov zoo ntawm ultrasonic vuam.
Niaj hnub no, qee cov yas xws li PE, PC, ABS, PP, PVC, proline, nylon, polyester tuaj yeem tau txais cov txiaj ntsig zoo tshaj plaws los ntawm kev siv ultrasonic vuam, tam sim no cov yas no kuj siv nyob rau hauv kev lag luam ntau tshaj plaws.Tom qab qhov kev nkag siab saum toj no, peb ntseeg tias cov pwm ntawm ultrasonic vuam tshuab tuaj yeem xaiv cov khoom tsim nyog, zam qhov tsis tsim nyog, txhim kho cov khoom zoo, txo cov nqi khiav lag luam, thiab txhim kho ntau lawm efficiency.
