Dab tsi yog qhov txawv ntawm PET preform txhaj tshuaj molding tshuab thiab tus qauv txhaj tshuaj molding tshuab?

Ib tug kws tshaj lij PET preform txhaj tshuaj molding tshuab sib txawv hauv paus los ntawm lub hom phiaj dav dav txheej txheem txhaj tshuaj molding tshuab, Raws li nws tau tsim tshwj xeeb los hloov kho rau lub cev tshwj xeeb thiab tshuaj lom neeg ntawm PET resin, uas cov tshuab zoo tib yam tsis tuaj yeem ua kom haum. Cov khoom siv PET muaj qhov nqus dej siab, rhiab heev thermal degradation, tsawg yaj viscosity, thiab cov kev cai nruj rau plasticization uniformity thiab molding ceev, tag nrho cov uas xav tau tshwj xeeb tshuab configurations. Ua ntej thiab foremost, plasticizing system yog txawv kiag li. PET preform tshuab tau nruab nrog lub siab qis-shear ntsia hlau thiab chim nrog qhov ntev-rau-inch piv ntawm 24:1 rau 26:1, featuring qhov ntiav ntsia hlau grooves thiab tsis muaj qhov tuag-angle tsim. Cov qauv no zam dhau lub zog shearing uas ua rau PET molecular saw tawg, zoo tiv thaiv yaj yellowing, carbonization, thiab pob tshab txo thaum lub sijhawm ua haujlwm kub. Qhov sib txawv, Cov txheej txheem txhaj tshuaj tshuab screws yog tsim los rau cov yas yas zoo li PP thiab ABS, Kev tsim hluav taws xob ntau dhau los uas yooj yim degrades PET cov ntaub ntawv thiab ua rau cov khoom tsis zoo nrog cov kab daj daj thiab daj ntseg.. Thib ob, qhov kub tswj qhov system ntawm PET preform tshuab txhawb ntau theem meej PID tswj qhov kub thiab txias, npog lub thoob, nozzle, thiab pwm adapter nrog kub yuam kev tswj tsis pub dhau ± 1 ° C. Txij li thaum PET ua haujlwm kub li ntawm 260 ° C txog 285 ° C, Txawm tias me me hauv zos overheating yuav ua rau acetaldehyde proliferation thiab cov khoom aging, ib qho teeb meem uas cov cav tov zoo tib yam nrog kev tswj qhov kub thiab txias tsis tuaj yeem zam tau. Ntxiv mus, PET preform ntau lawm yuav tsum tau ceev ceev nyias-phab ntsa filling thiab high-rigidity clamping los xyuas kom meej cov pwm xauv thiab tiv thaiv flash ntawm ntau kab noj hniav preforms. Cov kws tshaj lij preform tshuab txais cov qauv siv zog ua kom muaj zog thiab cov lus teb nrawm nrawm, ua tiav ruaj khov high-speed filling nyob rau hauv 0.1 vib nas this, thaum cov tshuab txheem muaj cov lus teb qeeb thiab tsis txaus clamping rigidity, ua rau tsis sib xws preform phab ntsa thickness thiab qis tawm los. Tsis tas li ntawd, Cov tshuab PET tshwj xeeb tau ua kom zoo rau cov khoom siv nyob hauv lub sijhawm luv, nrog streamlined flow channels thiab anti-stagnation nozzle qauv los txo cov yaj tuav thiab degradation. Lawv kuj khaws cov kev cuam tshuam kev tshaj lij rau cov khoom siv xws li dehumidifying dryers thiab industrial chillers, tsim kom tiav PET molding ntau lawm system. Cov tshuab txhaj tshuaj Standard tsis muaj cov phiaj xwm ua kom zoo dua, uas ua rau tsis muaj ntau lawm efficiency, tus nqi siab, thiab tsis muaj peev xwm ua tau raws li cov zaub mov-qib preform ntau lawm cov qauv. Hauv cov ntsiab lus, Cov tshuab txhaj tshuaj zoo tib yam tuaj yeem ua tiav cov yas molding yooj yim, thaum cov kws tshaj lij PET preform tshuab tsom rau qhov siab pom tseeb, qis acetaldehyde, siab tawm los, thiab high-speed mass ntau lawm, tag nrho txuam cov txheej txheem nruj heev ntawm PET preform manufacturing.
