1. Kev kho yas
Vim hais tias PET macromolecules muaj lipid pawg thiab muaj qee yam hydrophilic zog, cov nplej yog rhiab heev rau dej ntawm qhov kub thiab txias.Thaum cov dej cov ntsiab lus siab tshaj qhov txwv, PET molecular hnyav poob hauv kev ua, thiab cov khoom ua xim thiab nkig.
Yog li ntawd, ua ntej ua, cov khoom yuav tsum tau qhuav, nrog rau qhuav kub ntawm 150 ℃, ntau tshaj 4 teev;Feem ntau 170 ℃, 3-4 teev.Cov txheej txheem cua tuaj yeem siv los kuaj kom tiav ziab.Kev faib ua feem ntawm PET lub raj mis billet recycling cov ntaub ntawv feem ntau yuav tsum tsis txhob ntau tshaj 25%, thiab cov ntaub ntawv rov qab yuav tsum tau kom qhuav kom huv si.
2. Kev xaiv ntawm kev txhaj tshuaj molding tshuab
Vim tias PET muaj lub sijhawm ruaj khov luv luv tom qab lub melting point thiab lub siab melting point, nws yog ib qho tsim nyog los xaiv cov txheej txheem txhaj tshuaj nrog ntau qhov ntsuas kub thiab tsis muaj kev sib txhuam ntawm tus kheej thiab cov cua sov tsim thaum lub sij hawm plasticizing, thiab qhov hnyav ntawm cov khoom (xws li. cov khoom siv dej) yuav tsum tsis txhob tsawg dua 2/3 ntawm qhov kev txhaj tshuaj ntawm lub tshuab.
3. Pwm thiab pouring rooj vag tsim
PET lub raj mis embryo, feem ntau tsim nrog cov cua kub ntws channel pwm, pwm thiab txhaj tshuaj molding tshuab template ntawm qhov zoo dua kom muaj lub tshav kub rwb thaiv tsev phaj, nws thickness yog hais txog 12 hli, thiab lub tshav kub rwb thaiv tsev phaj yuav tsum muaj peev xwm tiv taus siab.Cov pa tawm yuav tsum txaus kom tsis txhob muaj cua sov hauv zos lossis tawg, tab sis qhov tob ntawm qhov chaw nres nkoj feem ntau tsis tshaj 0.03mm, txwv tsis pub nws yooj yim los tsim ya sab.
4. Melt kub
Muaj kev ntsuas huab cua-emission ntsuas, 270-295 ℃ ntau, qib GF-PET tuaj yeem teeb tsa rau 290-315 ℃, thiab lwm yam.
5. Ceev txhaj tshuaj
Qhov kev txhaj tshuaj dav dav yuav tsum ceev ceev kom tsis txhob muaj cov coagulation ntxov thaum txhaj tshuaj.Tab sis ceev heev, tus nqi shear yog siab, ua rau cov khoom tawg yooj yim.Qhov kev tua feem ntau ua tiav hauv 4 vib nas this.
6. Rov qab siab
Qhov qis dua qhov zoo dua, kom tsis txhob hnav.Feem ntau tsis tshaj 100bar, feem ntau tsis siv.
7. Lub sijhawm nyob
Tsis txhob siv lub sijhawm khaws cia ntev dhau los txhawm rau tiv thaiv qhov hnyav molecular poob, thiab sim zam qhov kub siab tshaj 300 ℃.Yog tias qhov kev kaw qis dua 15 feeb, tsuas yog ua kev kho cua tua;yog tias ntau tshaj 15 feeb, tom qab ntawd ntxuav nrog viscosity PE, thiab tso lub tog raj kheej kub rau PE kub, kom txog thaum rov pib dua.
8. Ceev faj
Cov khoom siv rov ua dua tsis tuaj yeem loj dhau, txwv tsis pub, yooj yim los tsim cov khoom siv "choj" thiab cuam tshuam rau plasticizing;
Yog tias cov pwm tswj qhov kub tsis zoo, lossis cov khoom siv ntsuas kub tsis tsim nyog, yooj yim los tsim "dawb pos huab" thiab opaque;cov pwm kub yog qhov tsawg thiab tsis sib xws, ceev ceev txias, tsawg crystallization, ces cov khoom yog pob tshab.
Huangyan Leiao Moulding Co., Ltd. yog nyob rau hauv Huangyan District pwm lub nroog, Taizhou, Taizhou xeev, uas yog "Lub hometown ntawm Suav pwm".Lub tuam txhab feem ntau yog koom nrog kev txhaj tshuaj pwm tsim, muaj ntau xyoo ntawm kev tsim pwm, feem ntau yog tsim thiab ua lub raj mis embryo pwm, PET khoom pwm, lub raj mis cap pwm, lub tsheb sab hauv thiab sab nrauv kho kom zoo nkauj pwm……. pwm system muaj nws tus kheej tshwj xeeb tsim thiab ua tshuab, raws li lub tswvyim ntawm "Kev Tswj Xyuas Kev Ncaj Ncees", nrog rau cov neeg siv khoom hauv tsev thiab txawv teb chaws los tsim kom muaj kev sib raug zoo ntawm kev koom tes ntev, Kuv ntseeg tias Leiao yuav yog koj tsim nyog ntawm kev ntseeg siab hauv kev koom tes. kev lag luam.
