Xyuam xim rau thaum txhaj tshuaj pwm UA TAU ZOO?

Yog xav tau PET tshuab nug FLYSE

1. Txheej txheem ntawm yas

Vim hais tias cov PET macromolecules muaj lipid pawg thiab muaj ib yam kawm ntawv ntawm hydrophilicity, Tus pellets muaj rhiab rhiab rau dej kub. Thaum cov dej teev tseg tsis pub tshaj qhov uas koj tau txais, Tus molecular luj ntawm PET decreases thaum txheej txheem, thiab cov khoom no yog xim thiab brittle. Yog li ntawd, Cov khoom yuav tsum dried ua ntej txheej txheem, thiab qhov qhuav qhuav yog 150°C rau ntau tshaj 4 Teev, feem ntau 170°C rau 3-4 Teev. Cov pa tshuaj txhaj tiv thaiv kab mob yuav siv tau los xyuas seb cov khoom no kiag li qhuav. Feem ntau, Cov kev faib ua feem ntawm recycled khoom yuav tsum tsis txhob tshaj 25%, Thiab cov khoom recycled yuav tsum tau thoroughly dried.

2. Xaiv cov tshuaj molding tshuab

Vim PET muaj ib lub sij hawm luv luv tom qab melting taw tes thiab siab melting taw tes, Nws yog tsim nyog xaiv ib qho txhaj tshuaj uas muaj peevxwm tswj seem thiab tsawg dua nws tus kheej friction tiam thaum yas, thiab qhov luj ntawm cov khoom (dej muaj khoom siv) Yuav tsum tsis txhob txhaj tshuab txhaj tshuaj. 2/3 tus nqi ntawm tus nqi. Raws li cov kev cai no, FLYSE tau tsim hauv me me thiab nruab nrab-sized PET yasizing lub nruab xyoo tsis ntev los no. Clamping quab yuam yog xaiv raws li ntau tshaj 6300t/m2.

3. Pwm thiab rooj vag tsim

TSIAJ preforms feem ntau yog ua los ntawm kub khiav pwm. Nws yog ib lub tshav kub insulation board ntawm lub puab tsaig thiab cov txhaj tshuaj molding template, Thiab nws thickness yog li 12mm, thiab sab nraud insulation board yuav tsum tau to taub siab. Tus exhaust yuav tsum txaus kom tsis txhob overheating los yog fragmentation, Tab sis qhov tob ntawm qhov chaw nres nkoj exhaust yuav tsum feem ntau tsis tshaj 0.03m, Txwv tsis pub nws yog ib qho yooj yim los ua flash.

4. Kub melt kub

Yuav ntsuas tau los ntawm tej huab cua-txhaj tshuaj. 270-295• Quaj, Tus enhanced GF-PET yuav muab teev rau 290-315°C, lwm yam.

5. Txhaj tshuaj

Feem ntau, qhov txhaj ceev ceev, uas yuav tiv thaiv tau premature solidification thaum txhaj tshuaj. Tab sis ceev heev, Tus nqi siab shear ua rau cov khoom brittle. Txhaj tshuaj tag li ntawm 4 vib nas this.

6. rov qab siab

Qhov zoo tshaj plaws, li ntawd, tsis txhob hnav. Feem ntau tsis ntau tshaj 100bar. Feem ntau tsis tas yuav tsum tau txhaj.

7. Chaw Nyob

Tsis txhob siv sij hawm ntev los tiv thaiv molecular poob. Sim kom kub li 300°C. Yog hais tias tus downtime tsawg tshaj li 15 Feeb. Nws tsuas yuav tsum tau air-txhaj tshuaj; yog hais tias nws yuav siv sij hawm ntau tshaj 15 Feeb, Nws yuav tsum tau ntxuav nrog viscosity PE, thiab qhov kub ntawm lub barrel yuav tsum txo qis rau lub PE kub kom txog thaum nws muab rau dua.

8. Ceev faj

1) Cov khoom recycled yuav tsum tsis muaj ib yam nkaus thiab loj heev, Txwv tsis pub nws yooj yim rau “Choj” Ntawm qhov chaw blanking thiab muaj feem xyuam rau cov yas. 2) Yog hais tias qhov chaw kub tsis zoo los yog qhov kub tsis zoo tswj tau, yooj yim “pos huab dawb” thiab opacity. Qhov kub yog tsawg thiab niaj hnub zoo li, qhov txias ceev ceev ceev, thiab cov khoom yog pob tshab uas tsis muaj crystallization.
