Thermoforming thiab Lub Tshuab Nqus Tsev Ua Dab Tsi?
Thermoforming piav qhia cov txheej txheem ntawm cov cua sov thermoplastic ntawv rau nws cov taw tes mos, ncab nws dhau lossis mus rau hauv cov pwm ib leeg, thiab tuav nws qhov chaw thaum nws txias thiab solidifies rau hauv cov duab xav. Daim ntawv thermoplastic yog clamped rau hauv cov cuab yeej tuav thiab rhuab los ntawm lub qhov cub siv los ntawm convection lossis radiant kub kom txog thaum nws muag muag. Daim ntawv yog tom qab ntawv tav toj dhau ib pwm thiab nias rau hauv los yog ncab dua cov pwm siv lub tshuab nqus tsev siab, siab cua, lossis siv tshuab quab yuam. Daim ntawv mos ua kom ua raws cov qauv pwm thiab tuav hauv qhov chaw kom txog thaum nws txias. Cov khoom siv dhau heev lawm ces maj mam txiav cia thiab qhov tsim ua ke yog tso tawm. Cov khoom siv dhau los tuaj yeem muab cov kab mob sib xyaw, sib xyaw nrog cov yas uas tsis siv, thiab kho dua tshiab rau hauv cov ntawv thermoplastic.
Thermoforming siv feem ntau rau kev ntim khoom noj, tab sis muaj ntau daim ntawv thov los ntawm cov khoom ua si yas mus rau cov cua tshuab ua kom lub tsev me me rau cov chaw noj mov hauv chaw noj mov. Daim ntaub nyias nyias (tsawg dua 0.060 ntiv tes) cov nplooj ntawv feem ntau yog siv rau cov khoom ntim zoo lossis cov khoom siv pov tseg, thaum cov ntawv tuab-tuab (ntau dua 0.120 ntiv taw) feem ntau siv rau cov chaw zoo nkauj tas mus li ntawm cov tsheb, chaw da dej, thiab khoom siv hluav taws xob. Ntau yam ntawm cov khoom siv thermoplastic tuaj yeem siv rau hauv tus txheej txheem no, suav nrog cov hauv qab no:
Acrylic (PMMA)
Acrylonitrile Butadiene Styrene (ABS)
Cellulose Acetate
Tsis tshua muaj ceev Polyethylene (LDPE)
Kev kub ceev Polyethylene (HDPE)
Polypropylene (PP)
Polystyrene (PS)
Polyvinyl Chloride (PVC)
Raws li tau hais los saum toj no, muaj ntau txoj kev sib txawv ntawm kev yuam lub thooj ntawv thermoplastic kom ua raws li cov pwm. Cov thermoforming hom no suav nrog cov hauv qab no:
Nqus plua plav ua - Lub tshuab nqus tsev yog tsim ntawm cov pwm kab noj hniav thiab cov ntawv thermoplastic. Lub tshuab nqus tsev siab (feem ntau 14 psi) yuam daim ntawv ua raws cov pwm thiab ua lub ntsej muag.
Lub tshuab nqus tsev txoj kev ua
Kev tsim siab siab - Ntxiv nrog rau kev siv lub tshuab nqus tsev hauv daim ntawv, cov cua ntsig (feem ntau 50 psi, tab sis txog li 100 psi) tau thov sab nraub qaum ntawm daim ntawv los pab yuam nws mus rau pwm. Qhov kev quab yuam ntxiv no ua rau cov ntawv tuab ntawm cov nplooj ntawv tuab thiab tsim cov lus ntxig ntxig, ntxhib los mos, tuav hauv qab, thiab cov ces kaum ntse.
Siab TausKev tsim tshuab - daim ntawv thermoplastic yog mechanically yuam mus rau lossis puag ncig cov pwm los ntawm kev sib chwv. Feem ntau, ib qho tseem ceeb sib txuas yuav thawb daim ntawv mus rau hauv cov kab noj hniav pwm thiab yuam nws rau hauv cov duab yam xav tau.
