Cov khoom siv tshuab yas vuam siv hauv ntau daim teb. Rau kev vuam tshuab, kev ua tau zoo yog qhov tseem ceeb, tab sis tsis yog txhua yam yas tuaj yeem txuas tau. Cov khoom siv tsis tau raws li qhov vuam xav tau, thiab lub vuam tshuab kuj tseem nyuaj rau kev ua tiav. Cov ntaub ntawv dab tsi tuaj yeem txuas los ntawm cov yas vuam tshuab? Kuv xav tias txhua tus neeg yuav tsum paub ntau txog qhov teeb meem no. Ntawm no yog cov khoom hauv qab no thiab qhia lawv nrog koj.
Muaj cov ntaub ntawv thermoplastic, elastomers thiab thermosetting resins: cov khoom siv thermoplastic yog cov yas uas kho kho kom sov thiab tsim nyog rau ultrasonic vuam. Elastomers yog cov yas ua los ntawm kev sib txuas sib txuas; lawv tsis teb rau ultrasound. Nws kuj yog qhov tsim nyog rau cov thermosetting resins uas tsis tuaj yeem siv los ntawm ultrasonic los ntawm kev kho txheej txheem.
Yas vuam txhais txhais cov khoom siv molecular sib khi ntawm cov ntaub ntawv thermoplastic. Cov kev cai dav dav: Tsuas yog tib cov khoom siv thermoplastic tuaj yeem txuas nrog sib npaug.
Txhua cov ntaub ntawv thermoplastic (tshwj tsis yog PTFE) tuaj yeem siv tau.
PC, PMMA thiab ABS tuaj yeem sib dhos ua ke nyob rau hauv qee yam kev mob. Los ntawm riveting, embedding thiab tuag forging, lwm yam ntaub ntawv tseem tuaj yeem sib raug zoo rau cov ntaub ntawv thermoplastic. Ib yam li ntawd, cov ntaub ntawv nyias xws li PET zaj duab xis lossis cov yeeb yaj kiab tuaj yeem siv los txhawm rau txhav yas ntu.
Cov khoom txiav txim siab txiav txim siab:
Tus qauv hluav taws xob: txhawb nqa lub suab kev sib luag thiab txiav txim siab txuas
Damping: txhawb cua sov
Melting point: txiav txim siab lub tshav kub xav tau
Cov yaj viscosity: lub ntsej muag-viscosity yaj tuaj yeem yooj yim tswj tau ntau ntxiv hauv thaj chaw koom, thiab cov txheej txheem ua ntu zus yog qhov tsis zoo dua
Cov xwm txheej hauv qab no muaj qhov tsis zoo ntawm kev lag luam solderability:
Cov tshuaj ntxiv rau, xws li hluav taws kev tiv thaiv zoo
Hws noo (tshwj xeeb polyamide)
Cov txuas ntxiv hauv qab no muaj qhov zoo rau kev ua haujlwm vuam:
iav fiber ntau
iav hlaws
Cov cuab yeej txhawb no mas txhim kho tus neeg ntawm semi-crystalline uas.
Cov ntaub ntawv yas sib txawv yuav cuam tshuam vuam rau ntau yam. Yog tias koj xav ua kom tau raws li qhov yuav tsum tau ua ntawm lub tshuab vuam thiab ua tiav cov txiaj ntsig, koj yuav tsum ua tib zoo ntawm kev xaiv cov ntaub ntawv. Tsis yog txhua tus yas siv tau. Qhov no xav kom txhua tus yuav tsum muaj kev nkag siab zoo.
