Gupakira ibicuruzwa bya Roll Filime Yacapwe Noodle Umufuka Gupakira Filime Umuvuduko mwinshi kuri 95 kugeza 121 ℃
Amafirime yo gupakira isafuriya arasaba kurwanya ubushyuhe bwo hejuru bwo hejuru (95-121 ° C), inzitizi zikomeye (kurwanya amazi na ogisijeni), imikorere myiza yo gufunga ubushyuhe, hamwe nimbaraga za mashini kugirango habeho gushya igihe kirekire no guhuza imirongo ikora ibicuruzwa byikora.
Ibikoresho bya PET / CPE ni amahitamo meza kubushyuhe bwo hejuru bwogupima no gutekesha noode kubera ibikorwa byayo byiza.

1. Imiterere yibikoresho: PET / CPE Igizwe na firime
(1) PET Layeri (Polyethylene Terephthalate)
- Imikorere: Itanga imbaraga nyinshi, kurwanya ubushyuhe, no gukorera mu mucyo mwinshi.
- Ibiranga:
- Kurwanya Ubushyuhe: Ingingo yo gushonga ~ 250 ° C, irashobora kwihanganira igihe kirekire cyo guhura na 121 ° C.
- Ibikoresho bya mashini: Imbaraga zingana cyane, zidashobora kumeneka, zibereye imashini zipakira byihuse.
- Ibyiza bya barrière: Umwuka mwiza wa ogisijeni n'amazi yo mu mazi, byongerera igihe cyo kubaho.
(2) Igice cya CPE (Chlorine Polyethylene)
- Imikorere: Itanga ibintu byoroshye no gufunga ubushyuhe, kwemeza kashe yuzuye.
- Ibiranga:
- Ubushyuhe bwo gushyushya: Gufunga ubushyuhe buke (110-130 ° C), bubereye imashini zipakira.
- Kurwanya imiti: Kurwanya aside na alkalis, birinda amavuta ya noode.
- Guhinduka: Kunoza ubunebwe bwa PET, kugabanya ingaruka zo gupakira.

2. Porogaramu: Ubushyuhe bwo hejuru-Ubushyuhe bwo Kumashanyarazi
- Kurwanya Ubushyuhe Bwinshi (95-121 ° C): Bikwiranye noode zihita, udon, ramen, nizindi node zisaba guhagarika amavuta.
- Kubungabunga inzitizi: Irinda okiside hamwe nubushuhe bwamazi, byongerera igihe cyo kubaho (amezi 6-12).
- Gupakira byikora: Bihujwe nimashini zipakira zihagaritse, kashe ya vacuum, nindi mirongo yihuta.
3.Ibipimo byingenzi byerekana imikorere
| Umutungo | Ikizamini | Agaciro gasanzwe |
| Kurwanya Ubushyuhe | ASTM D638 | Kurwanya igihe kirekire kuri 121 ° C. |
| Shyushya Ikimenyetso | ASTM F88 | .51.5N / 15mm |
| QTR | ASTM D3985 | ≤30 cm³ / m² · umunsi |
| WVTR | ASTM F1249 | ≤10 g / m² · umunsi |
| Imbaraga | ASTM D882 | ≥100 MPa (PET layer) |
4.Ibyiza bya PET / CPE:
✅ Kurwanya ubushyuhe bwo hejuru (121)°C)
✅ Inzitizi zisumba izindi (ubushuhe & okisijene irwanya)
✅ Imbaraga zidasanzwe za mashini (zibereye gupakira byihuse)
✅ Ikiguzi-cyiza, impirimbanyi nziza yimikorere nigiciro
5. Ibyifuzo byo gusaba
- Gupakira Ubushyuhe bwo hejuru cyane: Menya neza ko CPE irwanya ubushuhe nubushyuhe kugirango wirinde gusiba.
- Gushyushya Ikidodo Gushyushya: Hindura ubushyuhe bwo gufunga (110-130°C) hamwe nigitutu cyimbaraga nziza.
- Ikizamini cya Sterilisation: Kora 121°C / 30min ibizamini bya sterisizasiya kugirango igenzure ubunyangamugayo
Nyamuneka ohereza iperereza kubindi bisobanuro na cote.
