Kodi zinthu zazikulu zopangira cellulose ndi ziti?

Selosi, imodzi mwa mankhwala opangidwa ndi organic ambiri padziko lapansi, imagwira ntchito ngati gawo lalikulu la kapangidwe ka makoma a maselo a zomera. Polysaccharide yovutayi imapangidwa ndi mayunitsi obwerezabwereza a mamolekyu a shuga olumikizidwa pamodzi, kupanga maunyolo ataliatali. Zipangizo zazikulu zopangira cellulose zimachokera ku zomera, makamaka zamkati zamatabwa, thonje, ndi mitundu yosiyanasiyana ya zotsalira zaulimi.

Zamkati za Nkhuni:
Mitengo ya matabwa ndi zinthu zopangira kwambiri popanga cellulose, zomwe zimapangitsa kuti pakhale gawo lalikulu la cellulose padziko lonse lapansi. Imapezeka kuchokera ku ulusi wamatabwa, womwe umachokera ku mitengo ya matabwa ofewa ndi mitengo ya matabwa. Mitengo ya matabwa ofewa monga paini, spruce, ndi fir ndi yabwino kwambiri chifukwa cha ulusi wawo wautali komanso kuchuluka kwa cellulose, zomwe zimapangitsa kuti ikhale yabwino kwambiri popanga matabwa. Mitengo ya matabwa olimba monga birch, eucalyptus, ndi oak imagwiritsidwanso ntchito, ngakhale kuti njira zake zokonzera zinthu ndi zosiyana pang'ono chifukwa cha ulusi wawo waufupi komanso kapangidwe ka mankhwala osiyanasiyana.

Zamkati za nkhuni zimachotsedwa kudzera mu njira zingapo zamakina ndi mankhwala. Poyamba, matabwa amachotsedwa ndikudulidwa mzidutswa tating'onoting'ono. Kenako matumba awa amaphwanyidwa kapena kukonzedwa ndi mankhwala kuti alekanitse ulusi wa cellulose ndi zinthu zina monga lignin ndi hemicellulose. Zamkati zomwe zimatuluka zimatsukidwa, kupakidwa utoto, ndikukonzedwa kuti zipeze mtundu wa cellulose womwe ukufunika kuti ugwiritsidwe ntchito m'njira zosiyanasiyana.

Thonje:
Thonje, ulusi wachilengedwe wochokera ku mbewu za mbewu ya thonje, ndi gwero lina lofunika la cellulose. Limapangidwa makamaka ndi cellulose yoyera, yokhala ndi lignin yochepa kwambiri ndi hemicellulose. Thonje la cellulose limadziwika chifukwa cha kuyera kwake komanso mphamvu zake, zomwe zimapangitsa kuti likhale lofunika kwambiri popanga zinthu zapamwamba kwambiri za cellulose monga nsalu, mapepala, ndi zinthu zopangidwa ndi cellulose.

Njira yochotsera cellulose kuchokera ku thonje imaphatikizapo kulekanitsa ulusi ndi mbewu za thonje ndi zonyansa zina kudzera mu njira zingapo zopangira ginning, kuyeretsa, ndi kukonza makadi. Ulusi wa thonje womwe umachokera umakonzedwanso kuti uchotse zonyansa zilizonse zotsala ndikuyeretsa cellulose kuti igwiritsidwe ntchito mwanjira inayake.

Zotsalira za Ulimi:
Zotsalira zosiyanasiyana zaulimi, kuphatikizapo udzu, masagasi, chitofu cha chimanga, makoko a mpunga, ndi masagasi a nzimbe, zimagwiritsidwa ntchito ngati magwero ena a cellulose. Zotsalira izi ndi zochokera ku njira zaulimi ndipo nthawi zambiri zimakhala ndi cellulose, hemicellulose, lignin, ndi zinthu zina zachilengedwe. Kugwiritsa ntchito zotsalira zaulimi popanga cellulose kumapereka ubwino pa chilengedwe pochepetsa zinyalala ndikugwiritsa ntchito zinthu zongowonjezwdwanso.

Kuchotsa cellulose kuchokera ku zotsalira zaulimi kumaphatikizapo njira zofanana ndi kupanga zamkati zamatabwa, kuphatikizapo kuchepetsa kukula, kukonza mankhwala, ndi kuyeretsa. Komabe, kapangidwe ka mankhwala ndi kapangidwe ka zotsalira zaulimi zitha kusiyana ndi matabwa, zomwe zimapangitsa kuti pakhale kusintha kwa magawo ogwiritsira ntchito kuti pakhale kuchuluka kwa cellulose komanso ubwino wake.

Algae:
Ngakhale kuti sizigwiritsidwa ntchito kwambiri monga matabwa, thonje, kapena zotsalira zaulimi, mitundu ina ya algae imakhala ndi cellulose ndipo yafufuzidwa ngati magwero omwe angagwiritsidwe ntchito popanga cellulose. Algal cellulose imapereka zabwino monga kukula mofulumira, kuchuluka kwa cellulose, komanso kufunikira kochepa kwa nthaka ndi madzi poyerekeza ndi zomera zapadziko lapansi.

Kuchotsa cellulose kuchokera ku algae nthawi zambiri kumaphatikizapo kuswa makoma a maselo kuti atulutse ulusi wa cellulose, kenako kuyeretsa ndi kukonza kuti apeze zinthu zogwiritsidwa ntchito za cellulose. Kafukufuku wokhudza kupanga cellulose pogwiritsa ntchito algae akupitirira, cholinga chake ndi kupanga njira zokhazikika komanso zopindulitsa zopangira zinthu zazikulu.

zipangizo zazikulu zopangiraselulosikuphatikizapo zamkati zamatabwa, thonje, zotsalira zaulimi, komanso, pang'ono, mitundu ina ya algae. Zipangizo zopangira izi zimadutsa m'njira zosiyanasiyana zopangira ndi kuyeretsa cellulose, yomwe imagwira ntchito mosiyanasiyana komanso yofunika kwambiri m'mafakitale ndi mabizinesi osiyanasiyana, kuphatikizapo kupanga mapepala, nsalu, mankhwala, zakudya, ndi biofuels. Kupeza zinthu mokhazikika komanso ukadaulo watsopano wopangira zinthu kumapitilizabe kupititsa patsogolo kupanga cellulose, kukulitsa magwiridwe antchito, kuchepetsa kuwonongeka kwa chilengedwe, ndikukulitsa kugwiritsa ntchito kwa zinthu zachilengedwe zofunikazi.
