Impapuro zo mu bwoko bwa Kraft zikorwa binyuze mu buryo bwo gukurura imvubura, butuma impapuro zo mu bwoko bwa Kraft zikwiriye neza ibyo zagenewe gukoreshwa. Kubera ko hari amahame yoroshye yo kugabanya imbaraga zo guhangana n'ubudahangarwa, gucika, no gukomera, ndetse no kugabanuka kw'ubudahangarwa no kugabanuka kw'imyenge, impapuro zo mu bwoko bwa Kraft nziza cyane zikenera cyane kugira ngo habeho ibara, imiterere, imiterere, n'agaciro k'ubwiza.
Kugira ngo ibara n'ubwiza by'umutuku bigerweho, ifu y'umuhondo n'umutuku bigomba gusigwa kugira ngo bigire urumuri ruri hagati ya 24% na 34% mu gihe agaciro k'umuhondo n'umutuku by'ifu y'umuhondo n'umutuku kagumana agaciro gahoraho, ni ukuvuga kugumana imbaraga z'ifu y'umweru.
Uburyo bwo gukora impapuro z'ubudodo
Igikorwa cyo gukora impapuro z’ubudodo kirimo intambwe zikurikira.
1. Ibigize ibikoresho fatizo
Uburyo ubwo aribwo bwose bwo gukora impapuro burasa, butandukanye gusa n'ubwiza, ubugari, no kongeramo ibindi bisobanuro. Impapuro zikozwe mu giti ndende cya fibre, kandi zifite imiterere ihanitse. Ubu buryo butanga uruvange rw'imbaho zoroshye n'imbaho z'ibiti binini bihuye n'amahame y'ubuziranenge bw'impapuro z'igiciro cya kraft. Imbaho z'imbaho za Broadleaf zigize hafi 30% by'umusaruro wose. Iki gipimo cy'ibikoresho fatizo nta ngaruka bigira ku mbaraga z'impapuro, ariko bigira ingaruka zikomeye ku mucyo n'ibindi bipimo.
2. Guteka no gusiga ibara ry'uruhu
Ifu ya Kraft igomba kuba ifite uduce duto tw’imigozi ikomeye kandi ifite ibara rihoraho, ndetse ikanahuza n’ibisabwa kugira ngo itekwe neza kandi ikoreshwe mu buryo bwo gukaraba. Birazwi cyane ko imikorere yo guteka no gukaraba itandukana cyane hagati y’ibiti. Niba umurongo w’ifu ya pulp ushobora gutandukanya ifu ya softwood n’iy’ibiti bikomeye, guteka no gukaraba bishobora guhitamo ifu ya softwood n’iy’ibiti bikomeye. Iki cyiciro gikoresha guteka ifu ya coniferous n’iy’ibiti bikomeye, ndetse no guteka ifu ya bluewood nyuma yo guteka. Mu gukora, inenge z’ubwiza nko gukaraba ifu ya fiber idahuye, gukaraba ifu ya fibrous ikomeye, n’ibara ridahindagurika ry’ifu ya pulp ni ibintu bisanzwe.
3.Gukanda
Kunoza uburyo bwo gupfunyika ni intambwe ikomeye mu kongera ubukana bw'impapuro za kraft. Muri rusange, kongera uburyo zipfunyika mu gihe zigumana imyenge myiza no gukomera guke ni ngombwa kugira ngo impapuro zirusheho gukomera, ubucucike, no kuba zimwe.
Impapuro zo mu bwoko bwa Kraft zifite imbaraga nyinshi n'amakosa ashobora gupimwa mu kunyura mu buryo buhagaze no ku ruhande. Kubera iyo mpamvu, ingano ikwiye y'ubugari bw'impapuro, imiyoboro ya ecran, n'ibikoresho byo gushushanya urubuga bikoreshwa kugira ngo hongerwe amanota. Uburyo bwo gukanda bukoreshwa mu gukora impapuro bigira ingaruka ku kwinjira k'umwuka, gukomera no koroha. Gukanda bigabanya ubwiyongere bw'urupapuro, bigagabanya kwinjira no kuvamo umwuka mu gihe byongera ubushobozi bwo gufunga; bishobora kandi kongera imbaraga z'urupapuro.
Ubu ni bwo buryo impapuro za kraft zikunze gukorwamo.
