Ubujyakuzimu butandukanye bw'impapuro z'umugano

Dukurikije uburebure butandukanye bw'ubujyakuzimu, ifu y'impapuro z'imigano ishobora kugabanywamo ibyiciro byinshi, cyane cyane birimo Unbleached Pulp, Semi-bleached Pulp, Bleached Pulp na Refined Pulp, n'ibindi. Unbleached Pulp izwi kandi nka unbleached pulp.

1. Ibinure bitaravangwa

Impapuro za Bamboo zitarahinduka, izwi kandi nka pulp idahinduka, bivuga pulp iboneka mu buryo butaziguye mu mbaho ​​cyangwa mu bindi bikoresho by’umwimerere bya fibre y’ibimera nyuma yo kuvurwa mbere hakoreshejwe imiti cyangwa imashini, nta gusibanganya. Ubu bwoko bwa pulp bugumana ibara karemano ry’ibikoresho by’umwimerere, akenshi kuva ku muhondo werurutse kugeza ku mukara wijimye, kandi burimo igice kinini cya lignin n’ibindi bintu bitari selulose. Igiciro cyo gukora pulp y’amabara karemano ni gito, kandi ikoreshwa cyane mu mirima idasaba umweru mwinshi w’impapuro, nko mu mpapuro zo gupakira, mu makarito, mu gice cy’impapuro z’umuco n’ibindi. Akamaro kayo ni ugukomeza imiterere karemano y’ibikoresho by’umwimerere, bituma umutungo ukoreshwa neza mu buryo burambye.

2. Ibinure byakuweho ibara ry'umuhondo

Impapuro z'imigano zikozwe mu buryo bwa "semi-bleached paper" ni ubwoko bw'impapuro zikozwe mu buryo bwa "semi-bleached paper" hagati y'impapuro karemano n'impapuro zikozwe mu buryo bwa "bleached pulp". Zikorerwa mu buryo bwa "bleach" igice, ariko urwego rw'impapuro zikozwe mu buryo bwa "bleach" ntirungana n'urw'impapuro zikozwe mu buryo bwa "bleached pulp", bityo ibara riri hagati y'ibara karemano n'umweru gusa, kandi zishobora kuba zifite ibara ry'umuhondo runaka. Mu kugenzura ingano y'impapuro zikozwe mu buryo bwa "bleach" n'igihe cyo kuzikoresha mu gihe cyo kuzikoresha mu buryo bwa "semi-bleached pulp", birashoboka kwemeza ko umweru runaka uboneka mu buryo runaka ariko kugabanya ikiguzi cy'umusaruro n'ingaruka ku bidukikije. Ubu bwoko bw'impapuro bukwiriye ibihe hari ibisabwa kugira ngo impapuro zibe nziza ariko zitaba nyinshi cyane, nko mu bwoko bumwe na bumwe bw'impapuro zo kwandikaho, impapuro zo gucapa, nibindi.

3. Ibinure byakuweho ibara

Ifu y'impapuro z'imigano zikozwe mu ibumba ni ifu y'imirongo yuzuye ikozwe mu ibumba, ibara ryayo riri hafi y'umweru gusa, kandi ifite uburebure bwinshi. Ubusanzwe inzira yo gushushanya ikoreshwa mu buryo bwa shimi, nko gukoresha chlorine, hypochlorite, chlorine dioxide cyangwa hydrogen peroxide n'ibindi bintu bikoreshwa mu gushushanya, kugira ngo ikureho lignin n'ibindi bintu bifite amabara muri iyo fu. Ifu y'imirongo ifite ubuziranenge bwinshi bwa fibre, imiterere myiza y'umubiri n'ubudahangarwa bw'imiti, kandi ni yo mashini nyamukuru ikoreshwa mu mpapuro z'umuco zo mu rwego rwo hejuru, impapuro zihariye n'impapuro zo mu rugo. Kubera ko ifite umweru mwinshi kandi ikora neza cyane, ifu y'imirongo ifite umwanya ukomeye mu nganda z'impapuro.

4. Impapuro zitunganyijwe neza

Ubusanzwe, "Refined Pulp" yerekeza ku gishishwa cyabonetse hashingiwe ku gishishwa cyanduye, gikomeza kuvurwa hakoreshejwe uburyo bwa fiziki cyangwa imiti kugira ngo cyongere ubuziranenge n'imiterere ya fibre ya "fibre". Ubu buryo, bushobora kuba burimo intambwe nko gusya neza, gupima no gukaraba, bugamije gukuraho fibre nto, imyanda n'imiti idakora neza mu gishishwa no gutuma fibre zikwirakwira kandi zoroshye, bityo bikanoza uburyo bworoshye, ubwiza n'imbaraga by'impapuro. "Refined Pulp" ikwiriye cyane cyane mu gukora ibikoresho by'impapuro bifite agaciro kanini, nk'impapuro zo gucapa zo mu rwego rwo hejuru, impapuro z'ubugeni, impapuro zipfutse, nibindi, bifite ibisabwa cyane kugira ngo impapuro zibe nziza, zihuze kandi zihuze neza.
