Lintho tsa lik'hemik'hale tsa thepa ea bamboo

Lisebelisoa tsa bamboo li na le selulose e ngata, sebopeho sa fiber e tšesaane, thepa e ntle ea mochini le polasetiki. Joalo ka thepa e 'ngoe e ntle bakeng sa lisebelisoa tse tala tsa ho etsa pampiri, bamboo e ka fihlela litlhoko tsa ho etsa pampiri e mahareng le ea boleng bo holimo. Boithuto bo bonts'itse hore sebopeho sa lik'hemik'hale sa bamboo le thepa ea fiber li na le thepa e ntle ea ho hula. Ts'ebetso ea makhasi a bamboo ke ea bobeli feela ho makhasi a sefate sa coniferous, 'me e betere ho feta makhasi a mahlaku a sephara le makhasi a joang. Myanmar, India le linaha tse ling li ka pele ho lefats'e lefapheng la ho hula lehlaka le ho etsa pampiri. Lihlahisoa tsa China tsa bamboo le lihlahisoa tsa pampiri li rekoa haholo ho tsoa Myanmar le India. Ho nts'etsapele ka matla indasteri ea ho phunya lehlaka le ho etsa pampiri ho bohlokoa haholo ho fokotsa khaello ea hona joale ea lisebelisoa tse tala tsa lehong.

Bamboo e hola ka potlako mme ka kakaretso e ka kotulwa ka dilemo tse 3 ho isa ho tse 4. Ntle le moo, meru ea bamboo e na le phello e matla ea ho lokisa khabone, e leng se etsang hore melemo ea moruo, ea tikoloho le ea sechaba ea indasteri ea bamboo e hlahelle le ho feta. Hajoale, theknoloji ea China ea tlhahiso ea makhasi a bamboo le lisebelisoa li se li holile butle, 'me lisebelisoa tsa mantlha tse kang ho kuta le ho hula li entsoe ka lapeng. Mehala ea tlhahiso ea pampiri ea bamboo e meholo le e mahareng e entsoe liindasteri 'me ea kenngoa tlhahiso Guizhou, Sichuan le libakeng tse ling.

Lintho tsa lik'hemik'hale tsa bamboo
Joalo ka thepa ea biomass, bamboo e na le likarolo tse tharo tse kholo tsa lik'hemik'hale: cellulose, hemicellulose, le lignin, ntle le palo e nyane ea pectin, starch, polysaccharides le boka. Ka ho sekaseka sebopeho sa lik'hemik'hale le litšoaneleho tsa bamboo, re ka utloisisa melemo le likotsi tsa bamboo joalo ka makhasi le thepa ea pampiri.
1. Bamboo e na le selulose e ngata
Pampiri e phethiloeng e phahameng e na le litlhoko tse phahameng bakeng sa lisebelisoa tse tala tsa makhasi, e hlokang hore selulose e phahame, e be betere, 'me e theohele ka tlase ho lignin, polysaccharides le li-extracts tse ling. Yang Rendang et al. bapisa likarolo tse kholo tsa lik'hemik'hale tsa lisebelisoa tsa biomass tse kang bamboo (Phyllostachys pubescens), masson pine, poplar, le joang ba koro 'me ba fumana hore litaba tsa cellulose e ne e le masson pine (51.20%), bamboo (45.50%), poplar (43.24%), le joang ba koro (35.23%); litaba tsa hemicellulose (pentosan) e ne e le poplar (22.61%), bamboo (21.12%), joang ba koro (19.30%), le masson pine (8,24%); litaba tsa lignin e ne e le bamboo (30.67%), mason pine (27.97%), poplar (17.10%), le joang ba koro (11.93%). Hoa hlokomeleha hore har'a lisebelisoa tse 'ne tsa papiso, bamboo ke sehlahisoa se tala sa bobeli ho feta mason pine.
2. Likhoele tsa bamboo li telele ebile li na le karolo e kholoanyane
Karolelano ea bolelele ba likhoele tsa bamboo ke 1.49 ~ 2.28 mm, bophara bo tloaelehileng ke 12.24 ~ 17.32 μm, 'me tekanyo ea likarolo ke 122 ~ 165; karolelano ea lerako la fiber ke 3.90 ~ 5.25 μm, 'me karo-karolelano ea lebota-ho-cavity ke 4.20 ~ 7.50, e leng fiber e teteaneng e nang le karolo e kholoanyane. Lisebelisoa tsa pulp li itšetleha haholo ka selulose ho tsoa linthong tsa biomass. Lisebelisoa tse ntle tsa biofiber bakeng sa ho etsa pampiri li hloka li-cellulose tse ngata le li-lignin tse tlaase, tse ke keng tsa eketsa chai ea pulp feela, empa hape li fokotsa molora le li-extracts. Bamboo e na le litšoaneleho tsa likhoele tse telele le karo-karolelano e kholo, e etsang hore fiber e kopane makhetlo a mangata sebakeng se seng le se seng ka mor'a hore makhasi a bamboo a etsoe pampiri, 'me matla a pampiri a betere. Ka hona, ts'ebetso ea pulping ea bamboo e haufi le ea lehong, 'me e matla ho feta limela tse ling tsa joang tse kang joang, joang ba koro le bagasse.
3. Fiber ea bamboo e na le matla a phahameng a fiber
Bamboo cellulose ha e nchafatsoe feela, e senyeha, e sebelisana le biocompatible, hydrophilic, 'me e na le thepa e ntle ea mochini le e thibelang mocheso, empa hape e na le thepa e ntle ea mochini. Litsebi tse ling li ile tsa etsa liteko tse tsitsitseng mefuteng e 12 ea likhoele tsa bamboo ’me tsa fumana hore modulus ea tsona e reketlang le matla a tsona a thata a feta a likhoele tsa maiketsetso tse hōlang ka potlako tsa lehong. Wang et al. bapisa mekhoa e tsitsitseng ea mechine ea mefuta e mene ea likhoele: bamboo, kenaf, fir, le ramie. Liphetho li bonts'itse hore modulus e tsitsitseng le matla a fiber ea bamboo li ne li phahame ho feta tsa lisebelisoa tse ling tse tharo tsa fiber.
4. Bamboo e na le molora o phahameng le lintho tse nkiloeng
Ha ho bapisoa le lehong, bamboo e na le molora o phahameng (hoo e ka bang 1.0%) le 1% NAOH extract (hoo e ka bang 30.0%), e tla hlahisa litšila tse ngata nakong ea ts'ebetso ea pulping, e sa khoneng ho ntša metsi le ho hloekisa metsi a litšila. indasteri ea pampiri, 'me e tla eketsa litšenyehelo tsa matsete a lisebelisoa tse ling.

Hajoale, boleng ba lihlahisoa tsa pampiri ea bamboo ea Yashi Paper bo se bo fihletse litlhoko tse tloaelehileng tsa EU ROHS, bo fetisitse EU AP (2002) -1, US FDA le liteko tse ling tsa machabeng tsa boemo ba lijo, ba fetisitse setifikeiti sa meru sa FSC 100%. hape ke k'hamphani ea pele ea Sichuan ho fumana setifikeiti sa polokeho ea China le bophelo bo botle; ka nako e ts'oanang, e 'nile ea etsoa sampole e le "sampling ea boleng bo botle e tšoanelehang" ke Setsi sa Naha sa Tlhahlobo ea Lihlahisoa tsa Pampiri ka lilemo tse leshome tse latellanang,' me e boetse e hapile litlotla tse kang "Lets'oao la Naha le Ts'ebetso le Ts'ebetso ea Naha le Sehlahisoa" ho tsoa ho boleng ba China.
