Cov Txheej Txheem Ua Haujlwm ntawm Pob Zeb Ntawv Tsim Kab

Kab ntawv pob zeb thiab cov txheej txheem ua, uas muaj cov ntawv tsim thiab nws cov thev naus laus zis tsim tawm. Daim ntawv pob zeb muaj ib txheej ntawv hauv paus thiab ib txheej txheej txheej, txheej txheej txheej yog coated rau ntawm txheej ntawv hauv paus. Txheej ntawv hauv paus yog tsim los ntawm cov khoom organic thiab cov khoom inorganic. Cov khoom organic yog polylactic acid, thiab qhov hnyav ntawm cov khoom organic yog 15 txog 30. Cov khoom inorganic suav nrog lub teeb calcium carbonate thiab lithopone, thiab qhov hnyav ntawm cov khoom inorganic yog 70 txog 85. Txoj kev ua yog: cua sov-qhuav thiab dehydrate lub teeb calcium carbonate thiab lithopone thiab do lawv sib npaug, tom qab ntawd sib tov lawv nrog cov khoom inorganic thiab do lawv sib npaug, tom qab ntawd ua tiav sab hauv kneading thiab granulation hauv cov khoom siv granulation. Lub calender yog extruded kom tau txais cov txheej ntawv hauv paus, uas tom qab ntawd kho corona. Txheej cov khoom txheej txheej rau ntawm qhov chaw ntawm cov txheej ntawv hauv paus. Zoo rau ib puag ncig, yoog tau, thiab tiv taus kev quav thiab rhuav, nws yog qhov tsim nyog rau cov kua mem ib txwm thiab tuaj yeem siv ua ntawv kab lis kev cai, zaub mov thiab huv, phau ntawv sau thiab phau ntawv qhia, ntawv luam ntawv, thiab lwm yam.

cov Kev tsim cov ntawv pob zeb PE Kab muaj ntau yam ntawv pob zeb thiab cov txheej txheem ua, uas muaj cov ntawv tsim thiab nws cov thev naus laus zis ntau lawm. Ib hom ntawv pob zeb, muaj cov txheej ntawv hauv paus thiab cov txheej txheej, cov txheej txheej yog coated rau ntawm cov txheej ntawv hauv paus. Cov txheej ntawv hauv paus yog tsim los ntawm cov khoom organic thiab cov khoom inorganic. Cov khoom organic yog polypropylene, thiab qhov hnyav ntawm cov khoom organic yog 20 txog 30. Cov khoom inorganic suav nrog lub teeb calcium carbonate thiab lithopone, thiab qhov hnyav ntawm cov khoom inorganic yog 70 txog 80. Txoj kev ua yog: cua sov-qhuav thiab dehydrate lub teeb calcium carbonate thiab lithopone thiab do lawv sib npaug, tom qab ntawd sib tov lawv nrog cov khoom inorganic thiab do lawv sib npaug, tom qab ntawd nqa tawm sab hauv kneading thiab granulation hauv cov khoom siv granulation. Lub calender yog extruded kom tau txais cov txheej ntawv hauv paus, uas tom qab ntawd corona kho. Txheej cov txheej txheej khoom ntawm qhov chaw ntawm cov txheej ntawv hauv paus. Tus phooj ywg ib puag ncig, yoog tau, thiab tiv taus kev folding thiab tearing, nws yog tsim rau cov kua mem ib txwm thiab tuaj yeem siv ua ntawv kab lis kev cai, zaub mov thiab huv, phau ntawv sau thiab phau ntawv qhia, ntawv luam ntawv, thiab lwm yam.

PE pob zeb ntawv yog ib hom tshiab ntawm cov khoom siv ib puag ncig uas muaj ntau yam zoo thiab siv.

Nws feem ntau yog ua los ntawm hmoov limestone thiab polyethylene (PE) los ntawm cov txheej txheem tshwj xeeb. Nws yog dej tsis kam, roj tsis kam, noo noo tsis kam, thiab tiv thaiv khov. Nws kuj tiv taus kua muag, quav tsis kam, thiab tsis yooj yim rhuav. Haum rau ntau txoj kev luam ntawv, tshwj xeeb tshaj yog haum rau cov hnab ntawv, hnab tes, thiab lwm yam. Cov txheej txheem tsim khoom ntawm cov khoom no tsis siv dej, tsis siv roj lossis ntoo, tsis tas yuav khawb av loj, tsis tso tawm cov khib nyiab, qhov chaw tsim khoom huv si thiab tsis muaj suab nrov, tus nqi qis, yog ib hom khoom siv tshiab ntawm ntawv thiab yas.

Daim ntawv pob zeb PE tsis yog tsuas yog hloov tau qee cov ntawv ua haujlwm ib txwm muaj thiab cov ntawv tshaj lij xwb, tab sis kuj hloov feem ntau ntawm cov yas ntim khoom ib txwm muaj, thiab muaj kev paub txog ib puag ncig zoo. Nws tsis tas yuav ntxuav nrog dej thaum lub sijhawm tsim khoom, thiab nws tsis xav tau cov kua qaub muaj zog, alkali muaj zog thiab tshuaj dawb, yog li ntawd tsis muaj teeb meem ntawm kev tso dej khib nyiab, thiab nws tsis ua rau cov peev txheej dej xws li cov dej ntws thiab dej hiav txwv qias neeg. Thiab nws siv zog tsawg dua li cov ntawv ntoo pulp ib txwm muaj, pab txhim kho cov teeb meem xws li kev sov ntawm lub ntiaj teb los ntawm carbon dioxide (CO2).

Hauv kev xaus lus, PE pob zeb ntawv tsis yog tsuas yog cov khoom siv tshiab uas zoo rau ib puag ncig xwb, tab sis kuj muaj ntau yam zoo xws li tus nqi qis, kev siv rov qab tau thiab kev puas tsuaj, thiab xav tias yuav dhau los ua cov khoom siv zoo rau ib puag ncig uas siv dav hauv yav tom ntej.
