Dab tsi yuav cuam tshuam rau kev kho cov khoom yas ntawm Ultrasonic Vuam?
Jun 24, 2022
Cov ntaub ntawv sib txawv xws li extrusion, tshuab moulding lossis txhaj tshuaj molding thiab cov txheej txheem sib txawv yuav muaj qee yam cuam tshuam rau ultrasonic vuam.
A. Humidity defect
Cov av noo tsis xws luag feem ntau yog tsim nyob rau hauv cov txheej txheem ntawm ua striped los yog xoob yas qhov chaw. Humidity defects attenuate pab tau lub zog thaum vuam, uas ua rau lub sealing txoj hauj lwm seep thiab lengthens lub vuam lub sij hawm. Yog li ntawd, cov khoom yas nrog cov av noo siab yuav tsum tau qhuav ua ntej vuam. Xws li polyoxymethylene.
B. Cov nyhuv ntawm kev txhaj tshuaj molding txheej txheem
Kev hloov pauv ntawm cov txheej txheem txhaj tshuaj molding yuav ua rau muaj qhov tsis xws luag:
① Dimensional hloov (shrinkage, dabtsi yog khoov deformation)
② Qhov hnyav hloov
③ Kev puas tsuaj saum npoo
④ Tsis zoo ib yam
C. Txee lub neej
Tom qab cov khoom yas tau ua tiav los ntawm kev txhaj tshuaj molding, lawv feem ntau muab tso rau 24 teev ua ntej vuam, txhawm rau tshem tawm cov kev ntxhov siab, deformation thiab lwm yam ntawm cov khoom yas. Cov khoom yas ua los ntawm cov yas amorphous los ntawm kev txhaj tshuaj molding yuav tsis ua raws li qhov yuav tsum tau ua.
D. Recycled plastics
Cov khoom siv rov ua dua tshiab muaj lub zog tsis zoo thiab tsis zoo hloov mus rau ultrasonic vuam. Yog li ntawd, yog tias siv cov yas rov ua dua tshiab, ntau qhov tsim qauv yuav tsum raug txiav txim siab raws li qhov tsim nyog.
E. Tso tus neeg sawv cev thiab impurities
Pwm tso tus neeg sawv cev thiab impurities muaj qee yam cuam tshuam rau ultrasonic vuam. Txawm hais tias cov kuab tshuaj thiab cov impurities ntawm lub tshuab tuaj yeem raug shaken tawm thaum lub sij hawm ua ultrasonic, lawv yuav tsum tau muab tshem tawm kom ntau li ntau tau thaum sealing yuav tsum tau los yog thaum lub zog siab yuav tsum tau. Qee zaum, nws yuav tsum tau ntxuav cov khoom yas ua ntej.
