Impapuro zubukorikori zahindutse amahitamo bitewe nimbaraga zayo nyinshi, zitandukanye, hamwe ningaruka nke kubidukikije. Nibishobora gukoreshwa 100% kandi bitangiza ibidukikije, hamwe namateka maremare yumusaruro arimo fibre yibiti, amazi, imiti, nubushyuhe. Impapuro zubukorikori zirakomeye kandi zirarushijeho kuba nziza, bigatuma zikoreshwa muburyo budasanzwe. Ikoreshwa cyane mubipfunyika, nk'amakarito n'amashashi, kandi hariho ubwoko butandukanye bwashyizwe mubikorwa ukurikije imiterere n'intego.
1.Ibyoni impapuro?
Impapuro zerekana ubukorikori bivuga impapuro cyangwa ikarito ikozwe mu miti ikoresheje uburyo bwo gukora impapuro. Bitewe nuburyo bwo gushushanya, impapuro zubukorikori zifite igihe kirekire, zirwanya amazi, hamwe n’amarira, kandi ibara ryacyo ni umuhondo-umukara.
Ubukorikori bufite ibara ryimbitse kuruta izindi mbuto zimbaho, ariko irashobora guhumeka kugirango ireme umweru wera cyane. Kraft pulp yuzuye neza ikoreshwa mugukora impapuro zujuje ubuziranenge aho imbaraga, umweru, no kurwanya umuhondo ari ngombwa.
2. Amateka nuburyo bwo gutunganya impapuro zubukorikori
Impapuro zubukorikori, ibikoresho bisanzwe bikoreshwa mubipfunyika, byitirirwa inzira ya pulping. Igikorwa cyo gukora impapuro zahimbwe na Carl F. Dahl i Danzig, muri Prussia (ubu ni Gdańsk, Polonye) mu 1879. Izina ry'ubukorikori rikomoka ku ijambo ry'Ubudage "Kraft", risobanura imbaraga cyangwa imbaraga.
Ibintu byibanze byo gukora kraft pulp ni fibre yinkwi, amazi, imiti, nubushyuhe. Kraft pulp ikorwa mukuvanga fibre yibiti hamwe nigisubizo cya soda ya caustic na sodium sulfide hanyuma ukabiteka muri digester.
Nyuma yo kunyura mubikorwa bitandukanye byo gukora nko gutera akabariro, guteka, guhumeka, gukubita, ubunini, kwera, kweza, kwerekana, gukora, kubura umwuma no gukanda, kumisha, kalendari, no guhinduranya, hamwe no kugenzura neza, amaherezo ya kraft ihinduka. impapuro.
3. Impapuro zubukorikori nimpapuro zisanzwe
Bamwe bashobora kuvuga ko ari impapuro gusa, none niki kidasanzwe mubipapuro byubukorikori?
Mumagambo yoroshye, impapuro zubukorikori zirakomeye.
Bitewe nubukorikori bwa kraft yavuzwe haruguru, lignin nyinshi ikurwa muri kraft pulp yimbaho zimbaho, hasigara fibre nyinshi. Ibi biha impapuro kwihanganira amarira no kuramba.
Impapuro zidafite ubudahangarwa akenshi ziba zoroshye kuruta impapuro zisanzwe, zishobora kuvamo ibisubizo bike byo gucapa. Nyamara, iyi porosity ituma ikwiranye cyane nuburyo bwihariye, nko gushushanya cyangwa gushyirwaho kashe.
4.Ibisabwa byimpapuro zubukorikori
Muri iki gihe, impapuro z'ubukorikori zikoreshwa cyane cyane mu dusanduku twafunitse no mu gukora imifuka y'impapuro zidafite ingaruka za pulasitike, nk'izikoreshwa muri sima, ibiryo, imiti, ibicuruzwa, n'ifu.
Bitewe nigihe kirekire kandi gifatika, udusanduku dusobekeranye twakozwe mu mpapuro za kraft turazwi cyane mubikorwa byo kugemura no gutanga ibikoresho. Utwo dusanduku turinda neza ibicuruzwa kandi birashobora kwihanganira uburyo bwo gutwara ibintu nabi. Byongeye kandi, ikiguzi-cyiza cyimpapuro zerekana ko gikwiye guhitamo iterambere ryubucuruzi.
Agasanduku k'impapuro nako gakoreshwa kenshi n’amasosiyete kugira ngo agere ku ntego z’iterambere rirambye, yerekana neza ingamba zo kurengera ibidukikije binyuze mu buryo bubi kandi bubi bw’impapuro zijimye. Impapuro zubukorikori zifite intera nini ya porogaramu kandi irashobora gutanga zitandukanyegupakira udushyaibisubizo mubikorwa byo gupakira uyumunsi.
5. Ubwoko bwimpapuro
Impapuro zubukorikori akenshi zigumana ibara ryumwimerere wumuhondo-umukara, bigatuma bikenerwa no gukora imifuka nimpapuro. Hariho ubwoko butandukanye bwimpapuro zishingiye kumiterere no gusaba. Impapuro zubukorikori ni ijambo rusange ryimpapuro kandi ntabwo rifite ibipimo byihariye. Muri rusange ishyirwa mubikorwa ukurikije imiterere yayo nibigenewe gukoreshwa.
Ukoresheje ibara, impapuro zubukorikori zirashobora gushyirwa mubice byubukorikori karemano, impapuro zitukura, impapuro zera, impapuro zera, impapuro zanditseho impapuro, impapuro zuzuye impande zombi, impapuro zibiri zifite amabara abiri, nizindi.
Ukurikije ibyasabwe, impapuro zubukorikori zirashobora kugabanwa mubipfunyika byububiko, impapuro zidafite amazi, impapuro zubukorikori zometseho impapuro, impapuro zerekana ubukorikori, impapuro zishushanyijeho, impapuro zerekana ubukorikori, impapuro zerekana ubukorikori, nibindi byinshi.
Ukurikije ibiyigize, impapuro zubukorikori zirashobora gushyirwa mubice byongeye gutunganywa, impapuro zibanze, impapuro zifatizo, impapuro zerekana ibishashara, impapuro zishashara, impapuro zikoreshwa mu mpapuro, impapuro zikoreshwa mu buhanga, nizindi.
Ubwoko Bwisanzwe bwimpapuro
1. Impapuro zishushanyijeho impapuro (CUK)
Ibi bikoresho bifatwa nkibanze byibanze byimpapuro. Ntabwo ikora "guhumanya" cyangwa ibindi bintu byongera imiti, usibye imiti ikoreshwa mugikorwa cyo gutema. Nkigisubizo, bizwi kandi nkibikoresho bikomeye bitavanze cyangwa sulfite, bigizwe na 80% inkumi fibre fibre inkwi / selulose kraft pulp. Yerekana amarira meza yo kurwanya amarira no gukomera kutarinze kubyibuha cyane. Mubyukuri, ni ntoya cyane mubikorwa byose byapapuro bipfunyika.
2. Impapuro zikomeye zanditseho impapuro (SBS)
Mugihe impapuro zidafite ubudahangarwa zifatwa nkibidukikije bitewe n’ibara ryarwo ndetse no kutavura imiti, ntibishobora guhora ari amahitamo meza kubikorwa bimwe na bimwe, nko gupakira ibicuruzwa byiza cyangwa byo mu rwego rwo hejuru. Muri ibi bihe, impapuro zabugenewe zishobora gutoneshwa kuko zifite ubuso bworoshye kandi bugaragara neza, bushobora kuzamura ireme ryicapiro kandi bigatanga isura nziza kandi ikumva.
3. Ikibaho gitunganijwe neza (CRB)
Ikibaho gitwikiriwe neza gikozwe mu mpapuro 100% zongeye gukoreshwa. Kuberako idakozwe muri fibre yisugi, ibisobanuro byayo hamwe no kwihanganira biri munsi yizindi mpapuro zikomeye. Nyamara, impapuro zubukorikori zongeye gukoreshwa nazo ni igiciro gito cyo gupakira ibintu, bigatuma gikwiranye na porogaramu zidasaba kwihanganira amarira menshi cyangwa imbaraga, nk'agasanduku k'ibinyampeke. Kubisanduku bisobekeranye, ubwoko bwinshi burashobora kugerwaho wongeyeho kraft impapuro.
