Qhov no tsis yog - lub hnab nqa lub hnab ua tshuab yog lub siab - cov khoom siv precision txais cov cua sov- foob thiab txias - txiav tshuab nrog puv - txheej txheem nruj kaw- voj tswj. Zaj yeeb yaj kiab yog NW nyuam qhuav ncab thaum tsim khoom. Nws nta cov hnab uas tsis yog-deformable, siab qhov tseeb thiab ruaj khov, thiab zoo tagnrho rau cov yeeb yaj kiab mos, nyias zaj duab xis thiab biodegradable zaj duab xis.
1. Txoj Cai Ua Haujlwm
Dual servo & dual roj hmab cov menyuam pub mis: Cov menyuam pub mis thiab sizing roller conveying zaj duab xis synchronously. Lub sealing kab yog ib txwm nyob nruab nrab ntawm ob pawg ntawm cov menyuam, yog li lub sealing cheeb tsam bears yuav luag tsis muaj nro.
Tension kaw-loop tswj: Nruab nrog PLC, servo system thiab yees duab- hluav taws xob taug qab, nws ua tiav qhov tseeb ntawm ± 0.5mm thiab tswj qhov nro tas li thoob plaws hauv cov txheej txheem kom tsis txhob ncab thiab deformation.
Thaum tshav kub kub sealing & txias txiav: Cov yeeb yaj kiab yog thawj zaug los ntawm cov hniav kub, tom qab ntawd txiav tom qab txias, zoo tiv thaiv thinning, elongation thiab wrinkling los ntawm kub txiav.
Cov txheej txheem ua haujlwm: Unwinding → Tsis siv neeg hloov pauv hloov kho → Kev noj tsis tu ncua → Duab - hluav taws xob sizing → Thaum tshav kub kub sealing → Txias → Txias txiav → suav → Tshem tawm
2. Hom Lub Hnab Siv
- Lub hnab tiaj tus: hnab zaub mov, hnab cij, hnab tshuaj, hnab nqus tsev, hnab khoom plig
- T- lub hnab tsho: lub hnab ntim khoom noj khoom haus, hnab ntim khoom noj (nyiam dua rau cov yeeb yaj kiab mos thiab cov yeeb yaj kiab biodegradable)
- Lub hnab khib nyiab: lub hnab khib nyiab tiaj, lub hnab perforated yob, hnab khib nyiab drawstring
- Cov hnab ris tsho: hnab tsho, hnab ris tsho hauv qab, plua plav- cov hnab pov thawj pov thawj - Cov hnab ntim khoom siv biodegradable: PLA/PBAT cov hnab ntim khoom noj khoom haus biodegradable thiab cov hnab khib nyiab (tsis muaj elongation lossis tawg rau cov yeeb yaj kiab mos)
- Heavy-cov hnab ntim zaj duab xis tuab: hnab tshuaj, hnab pub, khoom siv plua plav- cov hnab pov thawj (lub zog ruaj khov)
Tsis siv rau: Thaum tshav kub kub shrinkable zaj duab xis hnab, sawv ntsug-pouches, zipper hnab, chaw- kaw & sab- kaw lub hnab laminated (tseem siv tshuab tshwj xeeb)
3. Cov ntsiab lus zoo
- Tsis muaj stretching & deformation: Yog qhov ntev, zoo huv si qhib lub hnab, tsis muaj distorted luam qauv thiab meej rau npe.
- Lub zog foob siab: Lub foob dav dav li ntawm 1mm mus rau 10mm rau kev xau- pov thawj kev ua haujlwm thiab ua kua muag zoo heev.
- Cov khoom siv dav dav: Ua haujlwm zoo nrog HDPE, LDPE, PP, OPP, PLA, PBAT thiab lwm yam. Nws khiav ruaj khov txawm tias cov yeeb yaj kiab nyias li 0.02mm.
- Kev kub ceev & pov tseg tsawg: Ntau lawm ceev: 80–200 hnab ib feeb, nrog pov tseg tus nqi tswj qis dua 1%.
- Zog-txuag & ruaj khov: 15%–20% qis zog siv dua li cov cav tov. Servo tsav kom tsis muaj suab nrov thiab ua haujlwm ntev.
