1. Dab tsi yogPob zeb?

Cov ntawv pob zeb yog ua los ntawm cov khoom lag luam zeb limestone nrog cov khoom loj (calcium carbonate cov ntsiab lus yog 70%) thiab cov khoom siv polymeriary (cov ntsiab lus yog 20-30%). Los ntawm kev siv lub ntsiab cai ntawm polymer interface chemistry thiab cov yam ntxwv ntawm polymer hloov kho, pob zeb yog tsim los ntawm polymer extrusion thiab tshuab tshuab tom qab ua tiav. Cov ntawv pob zeb muaj cov khoom lag luam tib yam thiab cov nyhuv luam ntawv ua cov ntaub ntawv fiber ntau. Nyob rau tib lub sijhawm, nws muaj cov khoom tseem ceeb ntawm cov hnab yas.

2. Cov yam ntxwv tseem ceeb ntawm daim ntawv pob zeb?

Lub pob zeb daim ntawv uas suav nrog kev nyab xeeb, lub cev, thiab lwm yam khoom siv tsis kam, thiab ntawm cov roj ntsha, thiab rau ntawm cov ntawv rhuav tshem tau zoo dua li cov ntoo pulp pulp.

Lub pob zeb luam ntawv yuav tsis yog etched nrog cov lus txhais siab, mus txog 2880dpi qhov tseeb, yuav tsis muaj tshuaj lom neeg nrog mem kua cam, uas yuav zam cov xim pov lossis decolorization prenomenon.

3. Vim li cas peb xaiv cov ntawv pob zeb?

a. Cov khoom siv nyoos kom zoo dua. Tsoos daim ntawv los haus cov ntoo ntau, thiab cov ntawv pob zeb yog cov khoom siv ntau tshaj plaws hauv lub ntiaj teb cov khoom siv roj carbonate raws li cov petrochemical - ib qho khoom siv petrochemical - ib qho khoom siv petrochemical - ib qho kev sib tw ntawm polyethylene (PE) txog 20%. Yog tias npaj cov ntawv sau txhua xyoo ntawm 5400Kt pob zeb ntawv, 8.64 lab m3 Wood tuaj yeem txuag txhua xyoo, sib npaug los txo cov deforestation ntawm 1010 square kilometers. Raws li cov txheej txheem ib txwm muaj ntawm kev siv dej ntawm 200t rau cov ntawv sau tawm hauv pob zeb tuaj yeem txuag 1.08 lab ntawm cov khoom siv dej txhua xyoo.

b. Ib puag ncig zooCov. Tag nrho cov txheej txheem ntau lawm ntawm pob zeb papermaking tsis xav tau dej, muab tsoos ua noj ua haus, ntxuav, tiv thaiv kev tiv thaiv kev lag luam qias neeg. Nyob rau tib lub sijhawm, cov ntawv siv pob zeb ua haujlwm tau xa mus rau tus neeg siv hluav taws, uas yuav tsis ua cov pa hluav taws dub, thiab cov hmoov av uas tseem tshuav tuaj yeem xa rov qab rau lub ntiaj teb thiab xwm.

Pob zeb papermaking zoo tshaj plaws txuag cov khoom siv hav zoov thiab cov khoom siv dej haus, thiab chav ntsuas kev noj haus tsuas yog 2/3 ntawm cov txheej txheem tsoos ua si.
