ABS tuab daim ntawv thermoforming yog ib qho ntawm cov txheej txheem tsim khoom siv dav tshaj plaws rau cov khoom siv tsheb, cov khoom siv hauv tsev, cov tais ntim khoom, thiab cov khoom ntim khoom. Paub txog qhov ua tau zoo heev, qhov ruaj khov, thiab tus nqi -kev ua tau zoo, ABS tuab- ntsuas qhov ntsuas kub muab cov khoom ruaj khov thiab siab - cov khoom tiav tiav. Tsis zoo li nyias-cov ntawv thermoforming, cov ntawv ABS tuab muaj cov cua sov ua haujlwm qeeb, ua kom qhov kub thiab txias tswj qhov tseem ceeb tshaj plaws kom tsis txhob tawg, bubbling, tsis sib xws ntawm phab ntsa thickness, thiab deformation.
Covoptimum nto cua sov ntau yamrau ABS tuab daim ntawv yogCi ntawm 150 txog 180 degrees. Tsis pub dhau qhov no, ABS ua tiav lub xeev zoo tshaj plaws viscoelastic, txhawb nqa kev sib sib zog nqus sib sib zog nqus thiab ua kom zoo ib yam. Rau kev tsim khoom loj nrog tus qauv 3-10mm ABS cov ntawv, qhov pom zoo ntsuas qhov ntsuas kub zoo yog160℃rau 170 degree, uas sib npaug formability thiab cov khoom ua haujlwm zoo kawg nkaus.
Kev sib txawv ntawm qhov kub thiab txias yuav ncaj qha ua rau cov khoom tsis raug. Yog tias qhov kub thiab txias qis dua 150 degree, daim ntawv tseem nruj nrog cov yas tsis txaus, uas ua rau kom tawv nqaij tawv nqaij, tawg nto, thiab cov khoom tsis meej. Thaum qhov kub siab tshaj 180 degree, ABS cov khoom raug thermal degradation, ua rau yellowing, npuas npuas, hauv zos nyias phab ntsa, thiab sagging deformation uas ua rau cov khoom tsis zoo.
Txhawm rau daws qhov teeb meem tsis sib xws sab hauv thiab sab nraud ntawm cov ntawv tuab,segmented gradient cua sovtau pom zoo. Lub preheating theem yog teem rau ntawm 120℃-140℃kom sov cov ntawv tseem ceeb maj mam thiab tshem tawm qhov kub qhov sib txawv. Cov txheej txheem txheej txheem tswj hwm 150℃-180℃kom ntseeg tau tias qhov muag muag ntawm tag nrho cov ntawv. Lub sij hawm cua sov sib txuam yog qhov tseem ceeb: 3-5mm cov ntawv yuav tsum tau 5-8 feeb ntawm cua sov, thaum 6-10mm tuab nplooj ntawv xav tau 10-15 feeb los tiv thaiv hauv qab - cua sov thiab tsis sib xws.
Ua ntej-kev kho mob thiab cov kev pabcuam pabcuam yog qhov tseem ceeb rau cov khoom lag luam ruaj khov. Cov nplooj ntawv ABS Hygroscopic yuav tsum tau ua ntej- ziab ntawm 80℃-85℃rau 2-4 teev kom txo tau cov dej noo thiab tshem tawm cov pits thiab npuas. Lub tshuab nqus tsev pom zoo yog -0.08MPa rau -0.1MPa, thiab pwm kub tswj ntawm 40℃-60 degree, uas ua kom nrawm nrawm, txo qis, thiab lav qhov ntev.
Saj zawg zog parameter hloov yog yuav tsum tau rau customized ntau lawm. Tsaus- cov ntawv ABS xim xim nqus cua sov sai dua thiab xav tau 5-10℃kub txo. Rau qhov sib sib zog nqus-kab noj hniav thiab complex- cov khoom zoo li tus, txais yuav qhov kev txwv sab saud ntawm tus qauv ntsuas kub los txhim kho cov khoom fluidity. Kev siv nruj ntawm cov qauv ntsuas kub thiab cov txheej txheem tsis zoo yog tus yuam sij rau kev ruaj khov ntau lawm thiab siab - zoo ABS tuab daim ntawv thermoforming khoom.
