Uburyo bwo gusibanganya uruhu rw'ibishishwa bya ECF mu gusiga uruhu rw'ibishishwa bya bamboo

Dufite amateka maremare yo gukora impapuro z'imigano mu Bushinwa. Imiterere n'imiterere y'imiti by'imigano ni umwihariko. Uburebure bw'imigano ni burebure, kandi imiterere y'urukuta rw'uturemangingo tw'imigano ni umwihariko. Ingufu zikura neza mu gihe cyo gukora impapuro ni nziza, bigatuma impumuro y'imirongo ihinduka urumuri cyane kandi ikagira ubushobozi bwo gukwirakwira mu rumuri. Ingano ya lignin mu bikoresho by'imigano (hafi 23%-32%) ni nyinshi, ibi bikaba bigaragaza ingano ya alkali nyinshi n'ingano ya sulfidation mu gihe cyo gukora no guteka (ingano ya sulfidation muri rusange ni 20%-25%), hafi y'ibiti bya coniferous. Ingano ya hemicellulose nyinshi na silicon mu bikoresho by'imigano nayo izana ingorane zimwe na zimwe mu mikorere isanzwe ya sisitemu yo koza impumuro n'ibikoresho byo gushonga by'umukara no guhumeka. Nubwo bimeze bityo, ibikoresho by'imigano biracyari ibikoresho byiza byo gukora impapuro.

Uburyo bwo gusibanganya umweru bw'ibimera binini n'ibiciriritse bikuramo imiti mu biti bya bamboo bukoresha uburyo bwo gusibanganya umweru bwa TCF cyangwa ECF. Muri rusange, hamwe no gusibanganya ubwinshi no gusibanganya umwuka wa ogisijeni mu gusibanganya umwijima, ikoranabuhanga ryo gusibanganya umwijima rya TCF cyangwa ECF rirakoreshwa. Bitewe n'umubare w'ibyiciro byo gusibanganya umweru, impumuro y'umugano ishobora gusibanganya ubwiza ku kigero cya 88%-90%.

Uduce twacu twa bleached bamboo pulp twose dusizweho ECF (idafite chlorine y’ibanze), dufite igihombo gito ku duce twa bleach kandi dufite ubukana bwinshi bw’uduce twa bleach, muri rusange tugera kuri 800ml/g. Uduce twa bleached bamboo twa ECF dufite ubuziranenge bwiza bw’uduce twa bleach, dukoresha imiti mike, kandi dufite ubushobozi bwo gutwikira neza. Muri icyo gihe, sisitemu y’ibikoresho iba imaze gukura kandi imikorere yayo irahamye.

Intambwe z'inzira yo gusibanganya imiterere ya ECF mu bice by'imigano bidafite chlorine ni izi: icya mbere, ogisijeni (02) yinjizwa mu munara wa ogisijeni kugira ngo ihindurwemo ogisijeni, hanyuma D0 ikarabya-isuka ...
