Imiterere y'ubutabire bw'ibikoresho bya bambu

Ibikoresho by'imigano bifite selulosi nyinshi, imiterere y'umugozi muto, imiterere myiza ya mekanike kandi bifite plastike. Nk'igikoresho cyiza cyo gukora ibikoresho by'ibanze by'ibiti, umugano ushobora kuzuza ibisabwa mu gukora impapuro ziciriritse n'izigezweho. Ubushakashatsi bwagaragaje ko imiterere y'imiti n'imiterere ya fibre by'imigano bifite imiterere myiza yo gusya. Imikorere ya pulp y'imigano ni iya kabiri nyuma ya pulp y'ibiti bya coniferous, kandi ni nziza kurusha pulp y'ibiti by'amababi manini n'ibyatsi. Miyanimari, Ubuhinde n'ibindi bihugu biri ku isonga ku isi mu bijyanye no gusya no gukora impapuro z'imigano. Ibicuruzwa by'imigano n'impapuro by'imigano mu Bushinwa bitumizwa cyane muri Miyanimari no mu Buhinde. Guteza imbere inganda zo gusya no gukora impapuro z'imigano ni ingenzi cyane mu kugabanya ibura ry'ibikoresho by'ibanze by'imigano by'ibiti ubu.

Imigano ikura vuba kandi muri rusange ishobora gusarurwa mu myaka 3 kugeza kuri 4. Byongeye kandi, amashyamba y'imigano afite ingaruka zikomeye zo gushyira karuboni mu karuboni, bigatuma inyungu z'inganda z'imigano zirushaho kugaragara mu bukungu, mu bidukikije no mu mibereho myiza. Kuri ubu, ikoranabuhanga n'ibikoresho byo mu Bushinwa byo gukora imigano byagiye bikura buhoro buhoro, kandi ibikoresho by'ingenzi nko kogosha no gusya byakozwe mu gihugu. Imirongo minini n'iciriritse ikora impapuro z'imigano yashyizwe mu nganda kandi ishyirwa mu bikorwa muri Guizhou, Sichuan n'ahandi.

Imiterere y'ubutabire bw'imiti y'umugano
Nk'ibikoresho bya biomass, umugano ufite ibice bitatu by'ingenzi bya shimi: cellulose, hemicellulose, na lignin, hiyongereyeho ingano nto ya pectin, starch, polysaccharides, na wax. Dusesenguye imiterere ya shimi n'imiterere ya bishingwe, dushobora gusobanukirwa ibyiza n'ibibi bya bishingwe nk'ibikoresho by'ibumba n'impapuro.
1. Bamboo ifite ubwinshi bwa selulosi
Impapuro zikozwe neza cyane zifite ibisabwa byinshi ku bikoresho fatizo, bisaba ko cellulose iba nyinshi, ni ko lignin, polysaccharides n'ibindi bivangwa biba byiza, kandi bikagabanuka, ni ko birushaho kuba byiza. Yang Rendang n'abandi bagereranije ibice by'ingenzi bya shimi bigize ibikoresho bya biomass nka bamboo (Phyllostachys pubescens), masson pine, poplar, n'ibyatsi by'ingano maze basanga ingano ya cellulose ari masson pine (51.20%), bamboo (45.50%), poplar (43.24%), n'ibyatsi by'ingano (35.23%); hemicellulose (pentosan) yari poplar (22.61%), bamboo (21.12%), ingano (19.30%), na masson pine (8.24%); lignin yari bamboo (30.67%), masson pine (27.97%), poplar (17.10%), n'ibyatsi by'ingano (11.93%). Bigaragara ko mu bikoresho bine bigereranywa, umugano ni wo musaruro w’ibikomoka ku mavuta wa kabiri nyuma ya masson pine.
2. Imigozi ya Bamboo ni miremire kandi ifite igipimo kinini cy'ubuso
Uburebure bw'imyenda ya bambu ni mm 1.49 ~ 2.28, umurambararo w'imyenda ni 12.24 ~ 17.32 μm, naho igipimo cy'ubuso ni 122 ~ 165; ubugari bw'imyenda ya bambu ni 3.90 ~ 5.25 μm, naho igipimo cy'ubuso hagati y'urukuta n'ubuso ni 4.20 ~ 7.50, ari byo bibumbano byuzuye inkuta bifite igipimo kinini cy'ubuso. Ibikoresho by'ubuso bishingiye ahanini kuri selulosi iva mu bikoresho bya biomass. Ibikoresho byiza bya biofiber mu gukora impapuro bisaba selulosi nyinshi n'ubunini buke bwa lignin, ibyo bikaba bidashobora kongera umusaruro w'imyanda gusa, ahubwo binagabanya ivu n'ibikomoka ku bimera. Bambu ifite imiterere y'imyenda miremire n'ubunini buke, ibyo bigatuma fibre ihuza inshuro nyinshi kuri buri gice nyuma y'uko imbambu ikozwemo impapuro, kandi imbaraga z'impapuro ziba nziza kurushaho. Kubwibyo, ubushobozi bwo gusya bwa bambu buri hafi y'ubw'ibiti, kandi burusha ibindi bimera by'ibyatsi nk'ibyatsi, ibyatsi by'ingano, na masashe.
3. Fibre y'imigano ifite imbaraga nyinshi za fibre
Selulosi y'imigano ntabwo ishobora kongera gukoreshwa, kwangirika, ihura n'ibinyabuzima gusa, irazima, kandi ifite ubushobozi bwiza bwo kwirinda ubushyuhe n'ingufu, ahubwo inafite ubushobozi bwiza bwo kurwanya ubushyuhe. Hari intiti zakoze ibizamini byo gukurura ku bwoko 12 bw'imirongo y'imigano maze zisanga modulus yazo yoroshye n'imbaraga zo gukurura zirenze iz'imirongo y'ibiti by'ishyamba ikura vuba. Wang n'abandi bagereranije imiterere y'imirongo y'imirongo y'imirongo ine: umugano, kenaf, fir, na ramie. Ibisubizo byagaragaje ko modulus yo gukurura n'imbaraga z'imirongo y'imigano byari hejuru y'ibindi bikoresho bitatu by'imirongo.
4. Igishishwa cy'imigano gifite ivu n'ibikomoka ku bimera byinshi
Ugereranyije n'ibiti, umugano ufite ivu riri hejuru (hafi 1.0%) na 1% by'ibikomoka kuri NAOH (hafi 30.0%), ibyo bikazana umwanda mwinshi mu gihe cyo gusohora, ibyo bikaba bitanozeza ikoreshwa ry'amazi mabi mu nganda zikora imyanda n'impapuro, kandi bizongera ikiguzi cy'ishoramari ry'ibikoresho bimwe na bimwe.

Kugeza ubu, ubwiza bw'ibicuruzwa bya Yashi Paper bya pulp pulp burageze ku bipimo ngenderwaho bya EU ROHS, bwatsinze EU AP (2002)-1, US FDA n'ibindi bipimo ngenderwaho mpuzamahanga by'ibiribwa, bwatsinze FSC 100% ishyamba, kandi ni na yo sosiyete ya mbere muri Sichuan yabonye icyemezo cy'umutekano n'ubuzima bwiza mu Bushinwa; muri icyo gihe, imaze imyaka icumi yikurikiranya ifatwa nk'ibicuruzwa byujuje ibisabwa mu kugenzura ubuziranenge bw'ibicuruzwa by'impapuro, kandi yanatsindiye ibihembo nka "National Quality Stable Qualified Brand and Product" bivuye mu irushanwa rya China Quality Tour.
