Tshwj xeeb Recycling Methods Rau Kraft Paper Laminated Bags (Paper + PE / PP Composite)

Lub ntsiab kev paub tab thev naus laus zis rau huab hwm coj laminated kraft hnab rov ua dua:
1.Ua ntej-kev kho mob: Tshem cov khib nyiab laminated hnab rau hauv cov khoom me me ntawm lub crusher.
2.Dej pulping & rubbing: Muab cov khoom tawg rau hauv lub tank dej loj; siab -kev ceev cov tshuab dov/rubbing dissolves kraft ntawv rau hauv cov ntaub so ntswg thaum cov khoom PE / PP yas zaj duab xis tseem nyob tsis tu ncua.
3. Kev sib cais & purification: Screen pulp los ntawm cov yas flakes nrog cov ntxaij lim dej; residual yas nyob rau hauv pulp yog muab tshem tawm ntawm centrifugal sorting.
4.Rov siv dua:
◦ Cov ntaub ntawv huv huv → rov ua dua los ua kom qis -qib ntawv kraft, cardboard, thawv ntawv
◦ cais cov yas flakes → ntxuav, qhuav, granulated rau hauv PE / PP yas pellets rau cov khoom yas tshiab los yog lub hnab tshiab hauv lamination

Lub cev cua sov sib cais yam tsis muaj dej immersion:
• Kub- lub hnab laminate rau 150–280℃; cov yas lamination txheej shrinks thiab tev tau los ntawm kraft ntawv vim txawv thermal expansion nqi.
• Manually lossis mechanically strip yas zaj duab xis tawm; ntawv mus rau pulping, yas rau granulation.
• Tsim nyog rau qhuav, huv si seem ntawm lub Hoobkas ntim khoom seem (tso noo noo cov ntsiab lus); tsis zoo tagnrho rau cov khoom siv qias neeg.

Txais yuav xaiv cov organic hnyav kom yaj PE / PP lamination thaum khaws cov ntawv fiber ntau:
1. Soak cov hnab sib xyaw hauv cov kuab tshuaj tshwj xeeb kom yaj cov txheej yas; daim ntawv fiber tseem tsis raug puas tsuaj.
2. Lim tawm pulp rau papermaking; distillation hnyav kom rov qab tau cov yas ntshiab.
• Feature: High sib cais purity, tsawg residual yas ntawm daim ntawv; tus nqi siab dua nrog kev kho cov dej khib nyiab uas xav tau, feem ntau yog rau siab - khoom noj muaj txiaj ntsig- qib cov hnab laminated.

• Ultrasonic sib cais: Siab- zaus vibration lov cov nplaum ntawm daim ntawv thiab yas ntawm qhov kub thiab txias, tsis muaj cua sov / tshuaj.
• Enzymatic decomposition: Bio-enzyme decomposes composite adhesive cais ob cov ntaub ntawv, tag nrho eco- phooj ywg, tam sim no nyob rau hauv loj - scale sim ntau lawm.
• Electrostatic sorting: Siv cov khoom sib txawv ntawm cov ntawv thiab cov yas kom nws pib- txheeb cov khoom tawg ntawm cov hluav taws xob zoo li qub tom qab sib tsoo.

(1)Muaj cov khib nyiab ntau (cov chaw tsim khoom, cov chaw tsim khoom noj / cement nrog cov khoom pov tseg loj):
Koom tes nrog cov kws tshaj lij kev ntim khoom ntim khoom siv rov ua dua tshiab: khaws cov khib nyiab laminated hnab nyias nyias, xa tawm ntau rau cov ntawv tshwj xeeb- cov nroj tsuag siv yas rov siv dua tshiab niaj hnub pov tseg.
(2)Tshaj tawm -cov khoom siv me me- ntim cov hnab siv:
1. Txheeb xyuas cov khoom ntim tshwj xeeb hauv zos uas hloov pauv hloov pauv hloov pauv -tawm chaw nres tsheb (ntau lub khw muag khoom noj khoom haus / cov khoom lag luam ntsuab rov ua dua tau txais cov hnab ntim khoom laminated).
2. Yog hais tias ua los ntawm compostable PLA / biodegradable lamination, xa mus rau cov chaw tsim khoom siv compost kom tag nrho degrade ua ke nrog ntawv, tsis xav tau kev sib cais.
