Cov khoom siv raw cov ntaub ntawv rau ntim ntawv feem ntau muaj cov nroj tsuag fibers, xws li ntoo pulp thiab cov ntawv siv dua tshiab.
Cov txheej txheem tsim khoom- tseem ceeb ntawm pulping thiab papermaking- suav nrog ntau theem, suav nrog cov ntaub ntawv pov tseg, kev tshuaj xyuas, purification, thickening, refining, thiab daim ntawv tsim.
Xyoo 2025, Sun Paper tau txais kev pom zoo los tsim ib qhov project nrog cov khoom tsim tawm txhua xyoo ntawm 700,000 tons ntawm qib siab - cov ntawv ntim qib. Siv cov ntaub ntawv siv dua tshiab thiab cov ntoo ua lag luam ua cov ntaub ntawv tseem ceeb, lub tsev siv cov txheej txheem ntau lawm nrog rau cov ntawv pov tseg, kev tshuaj xyuas, purification, thickening, refining, thiab daim ntawv tsim. Nyob rau hauv tib lub xyoo, lub tuam txhab cov kev txawj tej yam ntxiv project rau qib siab -qib kua ntim ntawv- khav theeb ib xyoos ib xyoos muaj peev xwm ntawm 480,000 tons{10}} ua tau zoo boosted muaj peev xwm los ntawm phasing tawm lub zog- cov khoom siv tsis siv neeg siv ntau thiab txhim kho cov tshuab refining tshiab.
Cov txheej txheem tsim tawm tshiab-xws li cov pob zeb-raws li eco-cov ntaub ntawv ntim khoom zoo- siv calcite (calcium carbonate) ua cov khoom siv raw. Ua ke nrog cov zaub mov-qib polypropylene (PP) thiab ntau yam khoom ntxiv, cov ntaub ntawv no yog tsim los ntawm kev ua lub cev, suav nrog granulation thiab ntawv extrusion.
Cov txheej txheem txheej txheem rau kev tsim cov ntawv ntim khoom los ntawm cov ntawv pov tseg rov ua dua muaj plaub theem tseem ceeb: deinking, ntawv fiber ntau purification, thickening, thiab papermaking.
