Sifofin sinadarai na bamboo
A matsayin kayan biomass, bamboo yana da manyan sinadarai guda uku: cellulose, hemicellulose, da lignin, ban da ƙaramin adadin pectin, sitaci, polysaccharides, da kakin zuma. Ta hanyar nazarin abubuwan da ke cikin sinadarai da halayen bamboo, za mu iya fahimtar fa'idodi da rashin amfanin bamboo a matsayin kayan bamboo da takarda.
1. Bamboo yana da yawan sinadarin cellulose
Takardar da aka gama da kyau tana da manyan buƙatu ga kayan albarkatun pulp, wanda ke buƙatar yawan sinadarin cellulose, mafi kyau, kuma ƙarancin sinadarin lignin, polysaccharides da sauran abubuwan da aka cire, mafi kyau. Yang Rendang da abokan aikinsa sun kwatanta manyan sinadaran kayan biomass kamar bamboo (Phyllostachys pubescens), masson pine, poplar, da bambaro na alkama kuma sun gano cewa sinadarin cellulose shine masson pine (51.20%), bamboo (45.50%), poplar (43.24%), da bambaro na alkama (35.23%); sinadarin hemicellulose (pentosan) shine poplar (22.61%), bamboo (21.12%), bambaro na alkama (19.30%), da masson pine (8.24%); sinadarin lignin shine bamboo (30.67%), masson pine (27.97%), poplar (17.10%), da bambaro na alkama (11.93%). Za a iya ganin cewa daga cikin kayan kwatantawa guda huɗu, bamboo shine kayan da ake amfani da su wajen girbe shuke-shuken da suka fi na masson pine.
2. Zaren bamboo sun fi tsayi kuma suna da babban rabo na al'ada
Matsakaicin tsawon zare-zare na bamboo shine 1.49 ~ 2.28 mm, matsakaicin diamita shine 12.24 ~ 17.32 μm, kuma rabon al'amari shine 122 ~ 165; matsakaicin kauri na zare shine 3.90 ~ 5.25 μm, kuma rabon bango zuwa rami shine 4.20 ~ 7.50, wanda shine zare mai kauri mai kauri tare da babban rabo. Kayan ɓoyayyen abu galibi sun dogara ne akan cellulose daga kayan biomass. Kyakkyawan kayan biofiber don yin takarda suna buƙatar babban abun ciki na cellulose da ƙarancin abun ciki na lignin, wanda ba wai kawai zai iya ƙara yawan abun ciki na ɓawon ba, har ma da rage toka da cirewa. Bamboo yana da halaye na dogon zare da babban rabo na al'amari, wanda ke sa zare ya haɗu sau da yawa a kowane yanki bayan an yi ɓawon bamboo zuwa takarda, kuma ƙarfin takarda ya fi kyau. Saboda haka, aikin ɓoyayyen abu na bamboo yana kusa da na itace, kuma ya fi ƙarfi fiye da sauran tsire-tsire masu ciyawa kamar bambaro, bambaro na alkama, da bagasse.
3. Zaren bamboo yana da ƙarfin zare mai yawa
Bamboo cellulose ba wai kawai yana da sauƙin sabuntawa ba, yana iya lalacewa, yana dacewa da halittu, yana da ruwa mai kyau, kuma yana da kyawawan halaye na juriya ga injiniya da zafi, amma kuma yana da kyawawan halaye na injiniya. Wasu masana sun gudanar da gwaje-gwajen juriya akan nau'ikan zare 12 na bamboo kuma sun gano cewa ƙarfin ƙarfin su na roba da ƙarfin juriya ya wuce na zare na itacen daji na wucin gadi da ke girma cikin sauri. Wang da abokan aikinsa sun kwatanta halayen injinan juriya na nau'ikan zare huɗu: bamboo, kenaf, fir, da ramie. Sakamakon ya nuna cewa ƙarfin juriya da ƙarfin zare na bamboo sun fi na sauran kayan zare uku.
4. Bamboo yana da yawan toka da kuma sinadarin da aka cire
Idan aka kwatanta da itace, bamboo yana da yawan toka (kimanin 1.0%) da kuma 1% na sinadarin NAOH (kimanin 30.0%), wanda zai samar da ƙarin ƙazanta yayin aikin fitar da fulawa, wanda ba ya da amfani ga fitar da ruwa da kuma maganin sharar gida na masana'antar barewa da takarda, kuma zai ƙara farashin saka hannun jari na wasu kayan aiki.
