ECF yibanze ya chlorine idafite uburyo bwo guhumeka kumigano

Dufite amateka maremare yo gukora imigano mu Bushinwa. Bamboo fibre morphologie hamwe nibigize imiti birihariye. Impuzandengo ya fibre ndende ni ndende, kandi fibre selile fibre microstructure irihariye. Imbaraga ziterambere ryiterambere mugihe cyo guswera nibyiza, biha impumyi nziza ya optique ya optique ya opacite yo hejuru hamwe na coefficient ikwirakwiza urumuri. Lignin irimo ibikoresho by'imigano (hafi 23% -32%) ni ndende, igena urugero rwa alkali nyinshi na dogere ya sulfidation mugihe cyo guteka no guteka (impamyabumenyi ya sulfidation ni 20% -25%), yegereye ibiti byera. . Ibirungo byinshi bya hemicellulose na silicon biri mubikoresho fatizo nabyo bizana ingorane zimwe na zimwe mumikorere isanzwe yo koza pulp hamwe no guhumeka inzoga z'umukara hamwe na sisitemu yibikoresho. Nubwo bimeze gurtyo, imigano mbisi iracyari ibikoresho byiza byo gukora impapuro.

Sisitemu yo guhumanya ibiti binini kandi biciriritse bivura imiti yimigano bizakoreshwa muburyo bwa TCF cyangwa ECF. Muri rusange, uhujwe no gusobanura byimbitse hamwe na ogisijeni yogusohora, tekinoroji ya TCF cyangwa ECF ikoreshwa. Ukurikije umubare wibyiciro byo guhumeka, imigano irashobora guhumeka kugeza 88% -90%.

Imigano yacu yimye yimigano yose yandujwe na ECF (elementarike ya chlorine yubusa), ifite igihombo gike cyo guhumeka kumigano yimigano no hejuru cyane, muri rusange igera kuri 800ml / g. ECF yanduye imigano ifite ubwiza bwa pulp, ikoresha imiti mike, kandi ifite uburyo bwiza bwo guhumeka. Mugihe kimwe, sisitemu yibikoresho irakuze kandi imikorere ikora irahagaze.

Intambwe yuburyo bwa ECF yibanze ya chlorine idafite umwanda wimigano ni: icya mbere, ogisijeni (02) yinjizwa muminara ya okiside kugirango igaragaze okiside, hanyuma D0 guhumura-gukaraba-gukuramo Eop gukuramo-gukaraba-D1 guhumura-gukaraba bikurikiranye nyuma yo gukaraba. Ibikoresho nyamukuru byangiza imiti ni CI02 (dioxyde de chlorine), NaOH (sodium hydroxide), H202 (hydrogen peroxide), nibindi. Umweru wimigano yimigano yimye irashobora kugera kuri 80%.
