Qhov zoo thiab qhov tsis zoo ntawm cov ntaub ntawv khob sib txawv

Cov khob ntawv yog cov khoom siv pov tseg hauv peb lub neej.Tam sim no, cov ntaub ntawv tseem ceeb ntawm lub khob ntim khoom suav nrog PE coated ntawv, PLA coated ntawv thiab cov ntawv yas tsis muaj khob.txawvntawv khob raw khoommuaj lawv tus kheej qhov zoo thiab qhov tsis zoo ntawm kev tiv thaiv ib puag ncig, degradability, thiab cov nqi tsim khoom.

1. Qhov zoo ntawm PE coated ntawv

PE coated ntawv yog cov khoom siv raw rau cov ntawv khob coated nrog polyethylene zaj duab xis rau ntawm daim ntawv.Qhov kom zoo dua yog tias nws muaj cov dej tsis zoo, uas tuaj yeem tiv thaiv cov dej nkag mus tau zoo, yog li lub khob ntawv tsis yooj yim kom xau mus rau qee yam.

Tsis tas li ntawd, tus nqi tsim khoom ntawmPE coated ntawv yobyog qhov tsawg, thiab kev siv tshuab ua haujlwm yooj yim, ua rau nws pheej yig, haum rau kev tsim khoom loj thiab siv.

Qhov tsis zoo

Txij li PE yog cov khoom siv yas, kev siv PE coated ntawv khob yuav ua rau cov khoom pov tseg ntawm cov yas thiab ua rau lub nra hnyav rau ib puag ncig.

Vim yog kev sib xyaw ua ke ntawm PE zaj duab xis thiab ntawv, kev rov qab thiab rov ua dua ntawm cov khob ntawv yuav nyuaj, thiab kev pov tseg tsis raug yuav ua rau muaj kuab paug rau ib puag ncig.

2. Qhov zoo ntawm PLA coated ntawv

PLA coated ntawv yog them nrog polylactic acid (PLA) zaj duab xis rau ntawm daim ntawv.PLA yog biodegradable yas ua los ntawm cov khoom siv raw, uas yog ib puag ncig zoo dua li cov khoom siv yas.Tom qab cov ntawv khob tau muab pov tseg, lawv tuaj yeem decomposed rau hauv cov khoom tsis muaj tshuaj lom thiab tsis muaj teeb meem tom qab kev kho kom raug, uas yog tus phooj ywg rau ib puag ncig.

PLA yog tsim los ntawm cov khoom siv txuas ntxiv dua tshiab xws li cov hmoov txhuv nplej siab cog thiab yog qhov tsawg dua nyob ntawm cov peev txheej petrochemical, pab txo qis kev xav tau ntawm cov khoom siv tsis txuas ntxiv.

Qhov tsis zoo
Vim muaj kev txwv ntawm cov txheej txheem ntau lawm thiab cov khoom siv raw khoom, PLA coated ntawv kuj tseem kim thiab cov nqi lag luam yog siab, yog li nws tsis haum rau cov khoom loj thiab cov nqi qis.

Lub biodegradation ntawm PLA xav tau qee qhov kub thiab av noo.Yog tias cov khib nyiab tsis raug kho raws li qhov tsim nyog, nws cov txiaj ntsig ecological yuav tsis muaj zog.

3. Qhov zoo ntawm cov ntawv yas tsis muaj ntawv

Cov ntawv tsis muaj yas yog hais txog cov khoom siv raw ntawm cov khob ntawv yam tsis tau ntxiv cov txheej yas.Qhov zoo dua yog tias nws yog ib puag ncig tus phooj ywg kiag li, degradable kiag li, thiab tsis muaj kev cuam tshuam rau ib puag ncig.

Nyob rau tib lub sijhawm, cov ntawv yas tsis pub siv cov cuab yeej tshwj xeeb tsis muaj dej tsis zoo los ua kom nws muaj qee yam dej tsis zoo, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev siv txhua hnub.

Qhov tsis zoo
Piv nrog PE-coated ntawv thiab PLA-coated ntawv, cov ntawv yas tsis muaj cov ntawv tsis zoo permeability, thiab cov teeb meem xau tuaj yeem tshwm sim thaum siv los yog tawm mus ntev.

Tam sim no, cov cuab yeej tsim khoom ntawm cov ntawv yas tsis muaj coated yog tseem nyob rau hauv txoj kev loj hlob, cov txheej txheem ntau lawm yog qhov nyuaj, thiab cov nqi tsim khoom kuj tseem siab, ua rau nws tus nqi kuj siab, uas tsis haum rau kev txhawb nqa loj thiab siv.

Cov ntaub ntawv khob sib txawv muaj lawv tus kheej zoo thiab qhov tsis zoo.Thaum xaiv cov khoom siv raw rau cov khob ntawv, cov yam ntxwv ntawm cov khoom sib txawv thiab cov kev xav tau siv tiag tiag yuav tsum raug txiav txim siab, txhawm rau sib npaug ntawm kev tiv thaiv ib puag ncig thiab nyiaj txiag txiaj ntsig, thiab siv zog los txo qhov cuam tshuam rau ib puag ncig.Nyob rau tib lub sijhawm, kev nce qib tsis tu ncua thiab kev tsim kho tshiab ntawm kev tshawb fawb thiab thev naus laus zis tseem yuav coj cov ntaub ntawv khob zoo dua, uas yog ntau dua nyob rau hauv txoj kab nrog lub tswv yim ntawm kev txhim kho kom ruaj khov.
