Gukora impapuro z'imigano mu Bushinwa bifite amateka maremare. Imigano ya fibre morphologie hamwe nibigize imiti bifite umwihariko. Impuzandengo ya fibre ndende ni ndende, kandi microstructure y'urukuta rwa fibre selile irihariye, gukubita mumbaraga zimikorere yiterambere rya pulp nibyiza, biha impumyi ihumeka neza ibintu byiza bya optique: opacite nyinshi hamwe na coefficient ikwirakwiza urumuri. Imigano mbisi ya lignin (hafi 23% kugeza 32%) iri hejuru, igena guteka kwayo hamwe na alkali na sulfide nyinshi (sulfide muri rusange 20% kugeza 25%), hafi yinkwi zumye; ibikoresho fatizo, hemicellulose hamwe na silicon biri hejuru, ariko kandi no gukaraba pulp, guhumeka inzoga z'umukara hamwe nibikoresho bya concentration imikorere isanzwe yazanye ingorane. Nubwo bimeze bityo, imigano mbisi ntabwo ari ibikoresho byiza byo gukora impapuro.
Ahazaza imigano iringaniye hamwe nini nini ya chimique pulp urusyo rwoguhumanya, bizakoresha muburyo bwa TCF cyangwa ECF. Muri rusange, ufatanije nubujyakuzimu bwa delignification hamwe na ogisijeni igenwa rya pulping, ikoreshwa rya tekinoroji ya TCF cyangwa ECF, ukurikije umubare wibice bitandukanye byo guhumanya, imigano irashobora guhishwa kugeza 88% ~ 90% yera ya ISO.
Kugereranya imigano ECF na TCF guhumanya
Bitewe na lignin nyinshi irimo imigano, igomba guhuzwa hamwe nogusobanura byimbitse hamwe na tekinoroji ya ogisijeni kugirango igenzure agaciro ka Kappa kanyerera yinjira muri ECF na TCF (bisabwa <10), ukoresheje Eop yazamuye ibyiciro bibiri ECF ikurikirana, aside kwiyitirira cyangwa Eop ibyiciro bibiri TCF ikurikirana, byose birashobora guhumeka imigano ya sulfate kugeza kumugaragaro hejuru ya 88% ISO.
Imikorere yo guhumanya yibikoresho fatizo bitandukanye byimigano iratandukanye cyane, Kappa kugeza 11 ~ 16 cyangwa irenga, kabone niyo haba ibyiciro bibiri byangiza ECF na TCF, ifu irashobora kugera kuri 79% kugeza 85% kurwego rwera.
Ugereranije na TCF imigano ya TCF, ECF yahanaguye imigano ifite igihombo gike cyo guhumeka hamwe nubukonje bwinshi, bushobora kugera kuri 800ml / g. Ariko na TCF igezweho yatunganijwe yimigano yimigano, viscosity irashobora kugera kuri 700ml / g gusa. ECF na TCF byujuje ubuziranenge bwa pulp ni ukuri kudashidikanywaho, ariko gusuzuma byimazeyo ubuziranenge bwamafaranga, ishoramari nigiciro cyo gukora, guhumisha imigano ukoresheje ECF byangiza cyangwa TCF byangiza, ntibirarangira. Abafata ibyemezo bitandukanye bafata imishinga bakoresha inzira zitandukanye. Ariko uhereye kumajyambere izaza, imigano ECF na TCF guhumanya bizabana igihe kirekire.
Abashyigikiye tekinoroji ya ECF bemeza ko ECF ihumanya ifu ifite ireme ryiza, hamwe no gukoresha imiti mike, uburyo bwo guhumeka neza, mugihe sisitemu yibikoresho ikuze kandi ikora neza. Icyakora, abunganira ikoranabuhanga rya TCF ryangiza bavuga ko tekinoroji ya TCF yo guhumanya ifite ibyiza byo gusohora amazi mabi ava mu ruganda rwangiza, ibisabwa bike byo kurwanya ruswa ku bikoresho, ndetse n’ishoramari rito. Sulfate bamboo pulp TCF ya chlorine idafite umurongo wa blachine ikoresha uburyo bwo guhumanya igice cyafunzwe, imyanda y’imyanda ihumanya ikirere irashobora kugenzurwa kuri 5 kugeza 10m3 / t. Amazi y’imyanda ava mu gice (PO) yoherejwe mu gice cyo kugena ogisijeni kugira ngo akoreshwe, kandi amazi y’amazi ava mu gice cya O atangwa mu gice cyo gukaraba kugira ngo akoreshwe, kandi amaherezo yinjira mu kugarura alkali. Amazi y’amazi ava mu gice cya Q yinjira muri sisitemu yo gutunganya amazi y’amazi yo hanze. Bitewe no guhumeka nta chlorine, imiti ntishobora kubora, ibikoresho byo guhumanya ntibikeneye gukoresha titanium nicyuma kidasanzwe, ibyuma bisanzwe bidafite ingese birashobora gukoreshwa, bityo igiciro cyishoramari kikaba gito. Ugereranije n'umurongo utanga umusaruro wa TCF, ECF pulp itanga umurongo w'ishoramari igiciro cyo gushora hejuru ya 20% kugeza kuri 25%, hamwe n'ishoramari ry'umusaruro wa pulp nawo uri hejuru ya 10% kugeza kuri 15%, ishoramari muri sisitemu yo kugarura imiti nayo nini, kandi imikorere iraruhije.
Muri make, imigano TCF na ECF ihumanya umusaruro wera cyane 88% kugeza 90% byuzuye imigano birashoboka. Guswera bigomba gukoreshwa muburyo bwimbitse bwo gusobanura, kwerekana ogisijeni mbere yo guhumeka, kugenzura ifumbire muri sisitemu yo guhumeka Kappa agaciro, guhumeka ukoresheje uburyo bwo guhumanya hamwe na bitatu cyangwa bine bikurikirana. Icyifuzo cya ECF cyo gukurikiranya kumigano ni OD (EOP) D (PO), OD (EOP) DP; L-ECF ikurikirana ni OD (EOP) Q (PO); Ikurikiranabikorwa rya TCF ni Eop (ZQ) (PO) (PO), O (ZQ) (PO) (ZQ) (PO). Nkuko ibigize imiti (cyane cyane ibirimo lignin) hamwe na fibre morphologie bitandukanye cyane muburyo butandukanye bwimigano, hakwiye gukorwa ubushakashatsi kuri gahunda yo gutema no gukora impapuro zubwoko butandukanye bwimigano mbere yo kubaka uruganda kugirango rutange ubuyobozi bwiterambere ryumvikana. inzira n'inzira.
