Cov ntaub ntawv xyoob muaj cov ntsiab lus cellulose siab, slender fiber ntau, cov kws kho zoo ib yam thiab cov yas. Ua ib qho kev xaiv zoo rau cov khoom siv raw ntoo, xyoob tuaj yeem ntsib lub sam thiaj rau kev ua nruab nrab thiab high-aire. Cov kev tshawb fawb tau qhia tias xyoob tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv fiber ntau muaj cov khoom zoo pulping. Cov kev ua yeeb yam ntawm xyoob sis xyoob yog ob tsuas yog rau cov ntoo coniferous, thiab yog qhov zoo dua li cov ntoo uas dav dav-ntoo thiab cov nyom pulp thiab cov nyom. Myanmar, Is Nrias teb thiab lwm lub teb chaws nyob ntawm qhov chaw ua ntej ntawm lub ntiaj teb hauv thaj teb xyoob ntoo thiab papermaking. Suav teb txoj kab xyoob ntshab thiab cov khoom siv yog feem ntau yog txawv teb chaws los ntawm Myanmar thiab Is Nrias teb. Kev tsim kho ob lub xyoob txuj ci thiab kev lag luam papermaking yog qhov tseem ceeb rau kev txo cov khoom siv tsis txaus ntawm ntoo pulp.
Xyoob tau loj hlob sai thiab feem ntau tuaj yeem muab tso rau hauv 3 mus rau 4 xyoos. Ib qho ntxiv, xyoob hav zoov muaj cov txiaj ntsig zoo ua kom zoo, ua kom muaj kev lag luam, ecological, ecological, pab ecological ntawm kev lag luam xyoob ntau ntxiv. Tam sim no, Tuam Tshoj txoj xyoob hlua roj ntau lawm, thiab cov khoom siv tseem ceeb xws li chais plaub hau tau ua haujlwm. Cov kab ntau thiab nruab nrab ntawm xyoob
Tshuaj lom neeg cov khoom ntawm xyoob
Raws li cov khoom siv biomass, xyoob muaj peb lub cellulose, teeb meem, thiab hnav me me ntawm pectin, hmoov txhuv nplej siab, polysaccharides, thiab siv quav. Los ntawm kev txheeb xyuas cov tshuaj lom neeg tshuaj lom neeg thiab cov yam ntxwv ntawm xyoob, peb tuaj yeem nkag siab txog qhov zoo thiab qhov tsis zoo ntawm xyoob ua lub sam thiaj li lub ntsws thiab cov ntaub ntawv ntawv.
1. Xyoob muaj cov ntsiab lus cellulose siab
Cov ntawv nyeem zoo dua muaj cov high solp raw cov ntaub ntawv, xav tau ntau dua cov ntsiab lus ntawm lignas, polysaccharides thiab lwm yam kev cia siab, zoo dua. Yang Rendang li al. piv rau cov khoom siv tseem ceeb ntawm biomass cov ntaub ntawv xws li xyoob (phyllostachys bine, parson pine, thiab hom kab cellulos yog pawg (55.50%), poplar (43.24%), Quav cab (35.23%); Lub Hemicellulose (Pentosan) cov ntsiab lus yog Poplar (22.61%), xyoob (21.12%), thiab masson ntoo thuv (8.24%); Cov ntsiab lus ligin yog xyoob (30.67%), Masson Pine (27.97%), Poplar (17.10%), thiab cov nplej ntoo (11.93%). Nws tuaj yeem pom tau tias ntawm plaub lub sij hawm cov ntaub ntawv sib piv, xyoob yog lub pulping raw khoom thib ob tsuas yog rau pawg ntoo thuv loj.
2. Xyoob cov hmoov nplej tau ntev dua thiab muaj qhov sib piv loj dua
Qhov nruab nrab ntev ntawm xyoob fibers yog 1.49 ~ 2.28 hli, lub taub nruab nrab yog 122 ~ 165; Qhov nruab nrab phab ntsa tuab ntawm cov fiber yog 3.90 ~ 5.25 μm, thiab phab ntsa-kab sib piv yog 4.20 ~ 7.20 Pulp cov khoom siv tsuas yog cia siab rau cellulose los ntawm cov ntaub ntawv biomass. Zoo biofiber raw cov ntaub ntawv rau papermaking xav tau cov ntsiab lus celluleming, uas tsis tuaj yeem ua kom tau lub samC tawm los, tab sis kuj tseem txo cov tshauv thiab rho tawm. Xyoob muaj cov yam ntxwv ntawm ntev fibers thiab cov nam loj piv, uas ua rau cov fiber ntau hauv cheeb tsam, thiab daim ntawv muaj zog zoo dua. Yog li ntawd, lub pulping kev ua tau zoo ntawm xyoob ntoo yog ze rau ntawm cov ntoo, thiab muaj zog tshaj lwm cov nroj tsuag nyom xws li quav nyab, thiab bagasse.
3. Xyoob fiber muaj cov muaj zog muaj zog
Xyoob cellulose tsis yog txuas ntxiv dua, tsis muaj txiaj ntsig, Hydrophilic, thiab cov cua sov ua haujlwm, tab sis kuj muaj cov khoom siv zoo. Qee cov kws tshawb fawb ua rau Tensile xeem ntawm 12 hom xyoob fibers thiab pom tias lawv txoj kev kawm loj heev thiab tensile lub zog tau dhau los ntawm cov ntoo hluav taws xob nrawm nrawm. Wang li al. Muab piv rau cov khoom siv tensile ntawm plaub hom fibers: xyoob, Kenaf, Fir, thiab Ramie. Cov txiaj ntsig tau pom tias cov tensile modulus thiab lub zog ntawm xyoob fiber tau siab dua li cov ntawm lwm peb cov ntaub ntawv fiber ntau.
4. Xyoob muaj cov hmoov tshauv tshauv thiab extract cov ntsiab lus
Piv nrog ntoo, xyoob muaj cov ntsiab lus tshauv muaj ntau dua (txog 1.0%) thiab 1% thiab 1.0%), uas tsis yog kev kho kom zoo rau cov pulp thiab dej khib nyiab ntawm pulp thiab Kev lag luam ntawv, thiab yuav ua rau cov peev nqi ntawm qee cov khoom siv.
Tam sim no, qhov zoo tshaj ntawm Yashi daim xyoob cov khoom siv tau mus txog EU ROHS cov qauv kev xav tau, dhau mus rau FSC 100% Hav Zoov Lij Choj, thiab tseem yog thawj lub tuam txhab hauv Sichuan kom tau txais cov ntawv pov thawj kev nyab xeeb thiab noj qab haus huv; Nyob rau tib lub sijhawm, nws tau raug piv txwv tias yog "kev saib xyuas zoo ua qauv tsim nyog" cov khoom lag luam los ntawm cov ntawv tshuaj xyuas kev sib law liag rau kaum sib lawrited hom thiab khoom "los ntawm Tuam Tshoj Zoo Ncig Saib.
