1. Dab tsi yogPob zeb ntawv?
Pob zeb ntawv yog tsim los ntawm limestone ntxhia cov peev txheej nrog loj reserves thiab dav faib raws li lub ntsiab raw khoom (calcium carbonate cov ntsiab lus yog 70-80%) thiab polymer li auxiliary khoom (cov ntsiab lus yog 20-30%). Los ntawm kev siv lub hauv paus ntsiab lus ntawm polymer interface chemistry thiab cov yam ntxwv ntawm kev hloov pauv polymer, pob zeb ntawv yog tsim los ntawm polymer extrusion thiab tshuab tshuab tom qab kev ua haujlwm tshwj xeeb. Cov khoom siv pob zeb muaj tib yam kev sau ntawv thiab kev luam ntawv zoo li cov ntawv cog fiber ntau. Nyob rau tib lub sijhawm, nws muaj cov khoom tseem ceeb ntawm cov ntim yas.
2. Cov yam ntxwv tseem ceeb ntawm cov ntawv zeb?
Cov ntaub ntawv pob zeb nrog rau kev nyab xeeb, lub cev, thiab lwm yam nta, thiab cov yam ntxwv tseem ceeb yog dej tsis qab, tiv thaiv pos huab, tiv thaiv cov roj, kab, thiab lwm yam, thiab ntawm lub cev lub cev muaj zog tearing kuj, folding kuj zoo dua li cov ntaub ntawv ntoo.
Lub pob zeb ntawv luam ntawv yuav tsis raug etched nrog cov ntsiab lus siab dua, mus txog 2880DPI qhov tseeb, qhov saum npoo tsis npog nrog zaj duab xis, yuav tsis muaj tshuaj lom neeg nrog tus cwj mem, uas yuav zam cov xim cam lossis decolorization tshwm sim.
3. Vim li cas peb thiaj xaiv cov ntawv zeb?
ib. Raw khoom kom zoo dua. Cov ntawv sau ib txwm siv ntau cov ntoo, thiab cov ntawv pob zeb yog cov khoom siv pob zeb ntau tshaj plaws hauv lub ntiaj teb cov pob zeb calcium carbonate ua cov khoom siv tseem ceeb, txog 80%, cov khoom siv polymer - petrochemical ntau lawm ntawm polyethylene (PE) txog 20%. Yog tias npaj ib xyoos ib xyoos ntawm 5400 kt pob zeb ntawv, 8.64 lab m3 ntoo tuaj yeem khaws cia txhua xyoo, sib npaug los txo cov hav zoov ntawm 1010 square kilometers. Raws li cov txheej txheem ib txwm siv dej ntawm 200t ib tuj ntawm daim ntawv, cov khoom tsim tawm txhua xyoo ntawm 5.4 lab tons ntawm cov ntawv pob zeb tuaj yeem txuag tau 1.08 lab tons ntawm cov dej txhua xyoo.
b. Environmental zoo. Tag nrho cov txheej txheem ntawm pob zeb papermaking tsis xav tau dej, piv nrog cov tsoos papermaking nws tshem tawm ua noj, ntxuav, tshuaj dawb thiab lwm yam kev ua qias tuaj, hauv paus daws cov tsoos papermaking kev lag luam pov tseg. Nyob rau tib lub sijhawm, cov ntawv pob zeb rov ua dua raug xa mus rau lub tshuab hluav taws xob rau incineration, uas yuav tsis tsim cov pa luam yeeb dub, thiab cov hmoov av inorganic tseem tuaj yeem xa rov qab rau lub ntiaj teb thiab xwm.
Pob zeb papermaking zoo heev txuag cov peev txheej hav zoov thiab dej, thiab chav siv hluav taws xob tsuas yog 2/3 ntawm cov txheej txheem papermaking.
