Zokambirana ndi Kuchita kwa White Kraft Paper Production Technology

White kraft pepala ndi mapepala apamwamba kwambiri, omwe angagwiritsidwe ntchito popanga zikwama zamtengo wapatali, maenvulopu, zikwama zamafayilo, ndi zina zotero, ndipo angagwiritsidwe ntchito ponyamula chakudya. M'zaka zaposachedwapa, ndi kukula mofulumira kwa makampani ma CD, kufunika msika kwapepala loyera la kraft m'dziko langa wakula mofulumira. Mabizinesi ena opanga mapepala apakhomo awonjezeranso kupanga ndi kupanga mapepala oyera a kraft, ndipo gawo la msika wa pepala loyera lanyumba likuchulukiranso. Chifukwa cha cholinga chapadera cha pepala loyera la kraft, pali zofunikira zapamwamba za zizindikiro za mphamvu. Malinga ndi zidziwitso zamapepala oyera a kraft omwe amasonkhanitsidwa ndi kafukufuku wamsika, poyerekeza ndi pepala loyera pakadali pano, pepala loyera la kraft lili ndi mphamvu zolimba komanso zolimba. pindani, kung'amba ndi kuchepetsa phulusa, mtengo wa Cobb. Kuti izi zitheke, tinasintha ndondomeko yopanga mapepala pochita zinthu monga kuchepetsa phulusa la pepala, kuwonjezera wowuma wa cationic, kusintha chiŵerengero cha zipangizo zopangira, ndikuwongolera kugunda kwa zamkati kuti zigwirizane ndi zofunikira zoyera.pepala la kraftndi kupanga nkhokwe zaukadaulo zopangira misala yotsatira.

Mu phunziro ili, luso lopanga mapepala a kraft loyera likukambidwa, ndipo njira zosinthira ndondomeko zimamveka bwino poyerekezera pepala loyera la kraft ndi pepala loyera. Ponena za kupanga pepala koyera, tapanga miyeso monga kuchepetsa phulusa la pepala, kuwonjezera wowuma wa cationic, kusintha kuchuluka kwa zamkati, kuwongolera kugunda kwa zamkati, etc. zinatsimikiziridwa motere: kuchuluka kwa softwood zamkati ndi 25% ndi hardwood zamkati ndi 75%, kumenya digiri onse ndi 40 ° SR, phulusa pepala ndi 21%, kuwonjezera cationic wowuma ndi 9 kg · T-1. wa pepala. Choyerakraftpepala lopangidwa ndi njirayi limakhala ndi mphamvu zambiri, kupikisana pamsika, komanso chiyembekezo chogwiritsa ntchito.
