Pulp Quality Evaluation

Ubwino wa zamkati umatsimikiziridwa makamaka ndi mawonekedwe ake a ulusi komanso ukhondo wa ulusi.Zomwe zili mbali ziwirizi zimatsimikiziridwa makamaka ndi mitundu yosiyanasiyana ya zipangizo zomwe zimagwiritsidwa ntchito, komanso njira yopangira ndi kuya kwake.
Pankhani ya fiber morphology, zinthu zazikuluzikulu ndizo kutalika kwa ulusi, kuchuluka kwa makulidwe a fiber cell khoma mpaka cell lumen m'mimba mwake, komanso zomwe zili m'maselo osakanizidwa opanda ulusi ndi mitolo ya ulusi mu zamkati.Nthawi zambiri, pafupifupi CHIKWANGWANI kutalika ndi lalikulu, chiŵerengero cha khoma makulidwe a selo m'mimba mwake kwa selo ndi yaying'ono, ndipo zamkati popanda kapena ochepa sanali fibrous maselo wosakanizidwa ndi CHIKWANGWANI mitolo ali ndi kugwirizana bwino mphamvu, kuchepa madzi m'thupi ndi papermaking katundu, ndipo akhoza kutulutsa amphamvu. pepala.Zamkati zapamwamba, monga zamkati za spruce softwood, thonje ndi zamkati zansalu, etc.
Pankhani ya ukhondo wa CHIKWANGWANI, zamkati zokhala ndi cellulose wambiri komanso zochepa zamagulu ena nthawi zambiri zimakhala zabwinoko.Mtundu uwu wa zamkati umakhala wokhazikika kwambiri, mphamvu yomangirira yolimba, yoyera kwambiri komanso kutchinjiriza kwamagetsi ndi zina zabwino kwambiri.

Kugwiritsiridwa ntchito kosiyanasiyana kwa pepala kumakhala ndi zofunikira zosiyanasiyana pakukula kwa zamkati.Sikoyenera kusankha zamkati zokhala ndi mawonekedwe abwino kwambiri a ulusi komanso ukhondo wapamwamba kwambiri.Ndipo zotsika mtengo zosiyanasiyana.Zamalonda ndi kupanga, zizindikiro zosiyanasiyana zoyendera zamtundu wa zamkati nthawi zambiri zimapangidwa molingana ndi zofunikira zosiyanasiyana zogwiritsira ntchito, monga kuwala kwa zamkati, kumasuka kwa madzi, kachigawo kakang'ono ka sieving, utomoni ndi phulusa, zomwe zili ndi cellulose, kuuma (zoyimira lignin), mphamvu ya thupi la pepala zamkati ndi zizindikiro zina zomwe zimakhudza ntchito ya mankhwala omalizidwa.Zizindikirozi ndizowonetseratu zamtundu wa fiber morphology ndi chiyero chake.Popanga mapepala, mwina zamkati zoyenera zitha kusankhidwa, kapena zamkati ziwiri kapena zingapo zamitundu yosiyanasiyana zitha kusankhidwa molingana.
