Dab tsi yog qhov kev txhaj tshuaj molding kub rau PC yas?
Dab tsi yog qhov kev txhaj tshuaj molding kub rau PC (polycarbonate) yas? Kev txhaj tshuaj molding kub ntau rau PC yas feem ntau yog siab, nyob ntawm cov khoom siv qib, cov khoom xav tau, thiab cov khoom siv. Cov hauv qab no yog cov ncauj lus kom ntxaws qhov ntsuas kub rau kev siv nkaus xwb.
1. Barrel Temperature (Segmented Control)
Sab nraub qaum (zaum pub mis): 250 ~ 280 degree
(Yuav kom tiv thaiv ntxov melting thiab ntsia hlau jamming)
Ntu nruab nrab (compression cheeb tsam): 280 ~ 310 degree
(Yuav kom muaj cov plasticization txaus)
Sab pem hauv ntej (metering cheeb tsam): 300 ~ 320 degree
(kom homogenize lub yaj; ntau ntau yog 280 ~ 320 degree, qee cov qib siab - ntws tuaj yeem qis li 260 degree)
2. Nozzle kub
Pom zoo ntau yam: 290 ~ 320 degree
(Yuav tsum qis dua me ntsis ntawm sab pem hauv ntej kom tsis txhob poob dej los yog degradation)
3. Pwm Kub
- Kev sib txawv: 80 ~ 120 degree
- Siab -gloss nto / complex qauv: 100 ~ 120℃(kom txo qis kev ntxhov siab sab hauv)
- Cov khoom qub: 80 ~ 100 degree
(qis dua 80℃tuaj yeem ua rau cov cim txias lossis kev ntxhov siab tawg)
4. Melt Temperature (Kev ntsuas qhov tseeb)
- Qhov zoo tshaj plaws: 280 ~ 320 degree
(Tuaj yeem lees paub nrog lub ntsuas kub infrared; tshaj 340℃yooj yim ua rau thermal degradation)
