Iipropathi zekhemikhali zeZinto zeBamboo

Izixhobo ze-bamboo zinomxholo we-seluplose ephezulu, i-fiber fiber fiber, iprojekhthi elungileyo kunye neplastiki. Njengenye into elungileyo yenye yeenkuni zeenkuni zenkuni ezivaliweyo, iBamboo inokuhlangabezana neemfuno zepulpi zokwenza iphepha eliphakathi neliphezulu. Izifundo zibonakalise ukuba ubume bekhemikhali ye-bamboo kunye nefreyiti zefibres zinezinto ezilungileyo zokutyhala. Intsebenzo ye-qarp ye-bamboo ikwisibini kuphela kwi-Prop Wood, kwaye ingcono kune-pulp ebanzi ebanzi kunye nengca. I-Myanmar, I-India nakwamanye amazwe iphambili emhlabeni kwicandelo le-bimboo etyhala kunye nepapermandu. I-China ye-China ye-china Ukuhlakulela ngamandla ukutywinwa kwe-bamboo kunye nemveliso yepakethi kubaluleke kakhulu ekupheliseni ukunqongophala kwangoku kweZinto eziPhinda zeWool.

I-Bamboo Grows ngokukhawuleza kwaye inokuthi ivunwe kwiminyaka emi-3 ukuya kweli-4. Ukongeza, amahlathi anamahlathi e-Bamboo aneziphumo zocwangciso lwekhabhoni eyomeleleyo, enza izibonelelo zoqoqosho, zendalo kunye nezentlalo zoMzi-mveliso weBamboo ngakumbi ngakumbi. Okwangoku, i-China ye-China ye-China Sulp yemveliso kunye nezixhobo ziye zakhula ngokuthe ngcembe, kwaye izixhobo eziphambili ezinjengokucheba kunye nokutsalwa kuye kwaveliswa. Imigca yemveliso enkulu nephakathi kwe-chaamboo ye-bibyuo ye-PAPOORMFOIRMFRO iye yakhiwe imibutho yaye yafunyanwa kwaye ifakwe kwimveliso eGuizhou, Sichuan kunye nezinye iindawo.

Iipropathi zeekhemikhali ze-bamboo
As a biomass material, bamboo has three major chemical components: cellulose, hemicellulose, and lignin, in addition to a small amount of pectin, starch, polysaccharides, and wax. Ngokuhlalutya ubume bekhemikhali kunye neempawu ze-bamboo, sinokuziqonda izibonelelo kunye nokungalunganga kwe-qambooo njenge-pulp kunye nephepha.
I-1. UBamboo unomxholo weselfowuni ephezulu
Iphepha eliphezulu eligqityiweyo lineemfuno eziphezulu zezinto eziluhlaza zePulp, ezifuna ukuphakama komxholo weselfowuni, ngcono, kwaye zinciphise umxholo we-LIGIN, i-polysacchaaccharides kunye nezinye izicatshulwa, ezingcono. Yang rendang et al. Xa kuthelekiswa nezinto eziphambili ze-bimass ezingu-biomass ezifana ne-bamboo (i-phyllostats), i-masson pine, i-piner, kunye nengca yengqolowa kwaye ifumene i-biles, i-bamboo (43.24%), kunye nengqolowa yengqolowa (35.23%); I-hemicellulose (iPentosan) yayinguPoplare (22.61%), i-bamboo (21.12%), ingqolowa yengqolowa (19.30), i-Masson Pine (8.24%); Umxholo we-LIGIN yayingu-bamboo (30.67%), i-Masson Pine (i-27.97%), i-Poplar (17.10%), kwaye i-Wloay Straw (11.93%). Ingabonwa ukuba phakathi kwezinto ezine zokuthelekisa, i-bamboo yindawo yokutsalwa kwezinto ezimbini kuphela kwipine.
2. Iintsinga ze-bamboo zihlala ixesha elide kwaye zinomlinganiso omkhulu
Ubude obuqhelekileyo beentsinga ze-1.49 ~ 2.28 mm, ububanzi bomndilili yi-12.24 ~ 17.32 μm, kwaye umyinge ophakathi kwe-122 ~ 165; Ubungakanani bodonga befayibha yefibrey yi-3.90 ~ 5.25 μm, kunye ne-rabo-to-cavity ratity i-4.20 ~ ifibutha ende ende enemilinganiselo enkulu. Izixhobo ze-Pulp ubukhulu becala zixhomekeke kwi-seluplose evela kwizinto zeBiomass. Izinto ezintle ze-biofiber ezinqabileyo ze-papermange zifuna umxholo weselselose ephezulu kunye nomxholo we-LINGIN ELINE, ongenako ukunyusa isivuno sepulp, kodwa sinciphise i-ash kunye nezicatshulwa. I-Bamboo ineempawu zentsimi ezinde kunye nenqanaba elikhulu, ezenza amaxesha amaninzi kwi-fiber yokungafaki kwicandelo ngalinye emva kwendawo ye-bimboo yenziwa ephepheni, kwaye amaphepha angcono. Ke ngoko, intsebenzo epeyintiweyo ye-bamboo isondele kolo nkuni, kwaye yomelele kunezinye izityalo zengca ezinje ngengca, ingca yengqolowa, kunye nengxowa.
I-3. I-bamboo fiber inamandla aphezulu e-fiber
I-Bamboo Selelose ayinakuphinda isebenze kuphela, ihlawulelwe, i-biompatid, i-hydrophilic, kwaye ineepropathi ezigqwesileyo kunye nobushushu, kodwa nazo zinepropathi elungileyo yobushushu. Abanye abaphengululi baqhuba iimvavanyo ze-tensles kwiintlobo ze-biber ezili-12 kwaye bafumanisa ukuba amandla abo e-elastic and thensles bagqitha kwizintso zehlathi elikhulayo. I-Wang et al. Xa kuthelekiswa neepropathi ze-tensle zoomatshini beentlobo ezine zeentsinga: Utamboo, iKenaf, Fir, neRamie. Iziphumo zibonise ukuba imodyuli ye-ntensle kunye namandla e-biber ye-bibeo yayiphezulu kunezo ezinye izinto ezintathu zefayibhi.
I-4. I-Bamboo ine-ash ephezulu kwaye ikhuphe umxholo
Xa kuthelekiswa neenkuni, i-bamboo inomxholo ophezulu (malunga ne-1.0%) kunye ne-1% I-1% I-5% ye-17.0%), eya kuthi ivelise impatho engaphezulu kwe-pulp kunye Umzi-mveliso wephepha, kwaye uyakonyusa iindleko zotyalo-mali zezixhobo ezithile.

Okwangoku, umgangatho weemveliso ze-bippe ze-challao zephepha le-quip le-EU ufikelele kwiimfuno ezisemgangathweni ze-EU ROHS, idlule kwi-EU AP (2002) -1, i-US FDA nezinye iimvavanyo ezisemgangathweni kwenqanaba lehlabathi, kwaye ikwayinkampani yokuqala eSichuan yokufumana ukhuseleko lwe-china kunye nokuqinisekiswa kwempilo; Kwangelo xesha, kuye kwanempungutye 'njengesampulu yokubekwa esweni "ngokubekiweyo" yiZiko leMidlalo leMidlalo yePhepha leSizwe elilandelelweyo, kwaye ikwayele i-radies efana ne-china "ukusuka kumgangatho we-China Ukhenketho.
