Kev tswj qhov kub thiab txias ntawm Kev Txhaj Tshuaj Molding rau kev ua cov pwm yas

1. Lub tog raj kheej kub: Qhov kub uas yuav tsum tau tswj xyuas thaum lub sij hawm txhaj tshuaj molding muaj xws li lub tog raj kheej kub, nozzle kub, thiab pwm kub. Thawj ob qhov kub thiab txias feem ntau cuam tshuam rau plasticization thiab ntws ntawm plastics, thaum qhov kub tom kawg feem ntau cuam tshuam rau qhov ntws thiab txias ntawm plastics. Txhua hom yas muaj qhov sib txawv ntawm qhov sib txawv. Vim muaj ntau qhov chaw lossis hom, qhov kub thiab txias decomposition ntawm tib cov yas sib txawv. Qhov no yog vim qhov sib txawv ntawm qhov nruab nrab molecular hnyav thiab molecular hnyav faib. Cov txheej txheem plasticization ntawm cov yas hauv ntau hom kev txhaj tshuaj tshuab kuj sib txawv, yog li qhov kub ntawm cov khoom ntim kuj txawv.
2. Nozzle kub: Qhov kub ntawm lub nozzle feem ntau yog me ntsis qis dua qhov kub ntawm sab saum toj ntawm lub thoob, thiaj li yuav tiv thaiv tau "salivation" ntawm cov khoom molten nyob rau hauv lub nozzle ncaj. Lub nozzle kub yuav tsum tsis txhob qis dhau, txwv tsis pub nws yuav ua rau ntxov solidification ntawm cov khoom molten thiab thaiv lub nozzle, los yog cuam tshuam rau kev ua tau zoo ntawm cov khoom vim yog txhaj tshuaj ntawm cov khoom thaum ntxov solidification rau hauv pwm kab noj hniav.
3. Pwm kub: pwm kub muaj qhov cuam tshuam loj rau kev ua haujlwm sab hauv thiab pom zoo ntawm cov khoom. Qhov kub ntawm cov pwm nyob ntawm qhov muaj lossis tsis muaj cov yas crystallinity, qhov loj thiab cov qauv ntawm cov khoom, kev ua tau zoo, thiab lwm yam txheej txheem (kua kub, txhaj tshuaj ceev thiab siab, pwm pwm, thiab lwm yam).
