Imiterere yimiti yibikoresho by'imigano

Ibikoresho by'imigano bifite selile nyinshi, selile ya fibre yoroheje, imiterere yubukanishi hamwe na plastike. Nkibindi bikoresho byiza byo gukora ibiti byo gukora impapuro, imigano irashobora kuba yujuje ibisabwa kugirango ikore impapuro ziciriritse kandi ndende. Ubushakashatsi bwerekanye ko imiti yimigano igizwe nimiterere ya fibre bifite imiterere myiza. Imikorere yimigano ni iyakabiri nyuma yimbaho ​​zimbaho, kandi iruta ibiti byamababi yagutse nibiti byatsi. Miyanimari, Ubuhinde ndetse n'ibindi bihugu biri ku isonga ku isi mu bijyanye no kuvoma imigano no gukora impapuro. Ubushinwa imigano n’ibicuruzwa biva mu mahanga biva muri Miyanimari no mu Buhinde. Gutezimbere cyane inganda zogosha imiganda ninganda zikora impapuro ningirakamaro cyane mugukemura ikibazo cyibura ryibiti byimbuto mbisi.

Umugano ukura vuba kandi ushobora gusarurwa mumyaka 3 kugeza 4. Byongeye kandi, amashyamba yimigano afite ingaruka zikomeye zo gutunganya karubone, bigatuma inyungu zubukungu, ibidukikije n’imibereho myiza yinganda zimigano zigenda zigaragara. Kugeza ubu, ikoranabuhanga n’ibikoresho byo mu Bushinwa by’imigano bigenda byiyongera buhoro buhoro, kandi ibikoresho by'ingenzi nko kogosha no gutema byakozwe mu gihugu. Imirongo minini nini nini yo gukora imigano yo gukora imigano yakozwe mu nganda kandi ishyirwa mu bikorwa muri Guizhou, Sichuan n'ahandi.

Imiti yimiti yimigano
Nkibikoresho bya biomass, imigano ifite ibintu bitatu byingenzi bigize imiti: selile, hemicellulose, na lignine, hiyongereyeho bike bya pectine, krahisi, polysaccharide, n’ibishashara. Dusesenguye imiterere yimiti nibiranga imigano, dushobora gusobanukirwa ibyiza nibibi byimigano nkibikoresho byimpapuro.
1. Umugano ufite selile nyinshi
Impapuro zuzuye zirangiye zifite ibisabwa byinshi kubikoresho fatizo bya pulp, bisaba ko ibintu byinshi biri muri selile, nibyiza, hamwe nibiri munsi ya lignin, polysaccharide nibindi bivamo, nibyiza. Yang Rendang n'abandi. ugereranije ibice byingenzi bigize imiti yibikoresho bya biyomasi nkumugano (Phyllostachys pubescens), pinusi ya masson, poplar, nicyatsi cy ingano ugasanga ibirimo selile byari pinusi ya masson (51,20%), imigano (45,50%), poplar (43,24%), n'ibyatsi by'ingano (35.23%); ibirimo hemicellulose (pentosan) byari poplar (22,61%), imigano (21,12%), ibyatsi by'ingano (19,30%), na pinusi ya masson (8,24%); ibirimo lignin byari imigano (30.67%), pinusi ya masson (27,97%), poplar (17,10%), hamwe n ibyatsi by ingano (11,93%). Birashobora kugaragara ko mubikoresho bine bigereranya, imigano harimo ibikoresho bibisi bya kabiri nyuma ya pinusi.
2. Fibre fibre ni ndende kandi ifite igipimo kinini
Impuzandengo ya fibre fibre ni 1,49 ~ 2,28 mm, impuzandengo ya diameter ni 12.24 ~ 17.32 mm, naho igipimo ni 122 ~ 165; impuzandengo y'urukuta rw'uburebure bwa fibre ni 3.90 ~ 5.25 mm, naho igipimo cy'urukuta na cavity ni 4,20 ~ 7.50, ni fibre ikikijwe n'inkuta nini ifite igipimo kinini. Ibikoresho bya pulp ahanini bishingiye kuri selile ivuye mubikoresho bya biomass. Ibikoresho byiza bya biofiber byo gukora impapuro bisaba selile nyinshi hamwe na lignine nkeya, ntibishobora kongera umusaruro wimbuto gusa, ahubwo binagabanya ivu nibisohoka. Umugano ufite ibiranga fibre ndende hamwe nigipimo kinini, bigatuma fibre ihuza inshuro nyinshi mugice kimwe nyuma yimigano ikozwe mumpapuro, kandi imbaraga zimpapuro nibyiza. Kubwibyo, imikorere yimigano yegereye iy'ibiti, kandi irakomeye kuruta ibindi bimera nk'ibyatsi, ibyatsi by'ingano, na bagasse.
3. Fibre fibre ifite imbaraga za fibre nyinshi
Bamboo selulose ntabwo ishobora kuvugururwa gusa, kwangirika, ibinyabuzima, hydrophilique, kandi ifite imiterere myiza yubukanishi nubushyuhe, ariko kandi ifite imiterere yubukanishi. Bamwe mu bahanga bakoze ibizamini bikaze ku bwoko 12 bw’imigano basanga modulus ya elastique n'imbaraga zabo zirenze iz'ibiti by’ibiti byo mu mashyamba bikura vuba. Wang n'abandi. ugereranije imiterere yubukanishi bwubwoko bune bwa fibre: imigano, kenaf, fir, na ramie. Ibisubizo byerekanaga ko modulus ya tensile n'imbaraga za fibre fibre byari hejuru ugereranije nibindi bikoresho bitatu bya fibre.
4. Umugano ufite ivu ryinshi nibikuramo
Ugereranije n’ibiti, imigano ifite ivu ryinshi (hafi 1.0%) hamwe na 1% ya NAOH ikuramo (hafi 30.0%), izabyara umwanda mwinshi mugihe cyo gutemba, ibyo bikaba bidahumeka gusohora no gutunganya amazi mabi ya pulp na inganda zimpapuro, kandi izongera igiciro cyishoramari ryibikoresho bimwe.

Kugeza ubu, ubwiza bw’ibicuruzwa by’imigano ya Yashi Paper byageze ku muryango w’ibihugu by’Uburayi ROHS, byatsinze Umuryango w’ubumwe bw’ibihugu by’Uburayi (2002) -1, US FDA n’ibindi bizamini mpuzamahanga by’ibiribwa, byatsinze FSC icyemezo cy’amashyamba 100%, kandi nisosiyete ya mbere muri Sichuan yabonye umutekano wubushinwa nicyemezo cyiza; icyarimwe, byatoranijwe nk'ibicuruzwa "byujuje ubuziranenge byujuje ubuziranenge" byakozwe n'ikigo cy'igihugu gishinzwe kugenzura ibicuruzwa by’impapuro mu myaka icumi ikurikiranye, kandi byatsindiye kandi icyubahiro nka "National Quality Stable Qualified Brand and Products" bivuye mu Bushinwa. Kuzenguruka.
