Kodi cellulose ndi polima wachilengedwe kapena wopangidwa?

Ma cellulosendi polima zachilengedwe, chigawo chofunikira cha makoma a selo mu zomera. Ndi imodzi mwazinthu zomwe zimapezeka kwambiri padziko lapansi ndipo zimagwira ntchito ngati zomangira muzomera. Tikaganizira za cellulose, nthawi zambiri timagwirizanitsa ndi kupezeka kwake mumatabwa, thonje, mapepala, ndi zinthu zina zosiyanasiyana zochokera ku zomera.

Mapangidwe a cellulose amakhala ndi unyolo wautali wa mamolekyu a shuga olumikizidwa palimodzi kudzera m'mabondi a beta-1,4-glycosidic. Unyolowu umakonzedwa m’njira yoti azitha kupanga zinthu zolimba, za ulusi. Mapangidwe apadera a maunyolowa amachititsa kuti cellulose ikhale yodabwitsa, zomwe zimapangitsa kuti zikhale zofunikira kwambiri pothandizira zomera.

Kaphatikizidwe ka cellulose mkati mwazomera kumaphatikizapo enzyme cellulose synthase, yomwe imapangitsa mamolekyu a shuga kukhala maunyolo aatali ndikuwatulutsa mu khoma la cell. Njirayi imapezeka mumitundu yosiyanasiyana ya maselo a zomera, zomwe zimathandizira ku mphamvu ndi kusasunthika kwa minofu ya zomera.

Chifukwa cha kuchuluka kwake komanso mawonekedwe ake apadera, cellulose yapeza ntchito zambiri kuposa momwe imagwirira ntchito pazachilengedwe za zomera. Mafakitale amagwiritsa ntchito cellulose kupanga mapepala, nsalu (monga thonje), ndi mitundu ina yamafuta amafuta. Kuphatikiza apo, zotumphukira zama cellulose monga cellulose acetate ndi cellulose ethers zimagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza mankhwala, zowonjezera chakudya, ndi zokutira.

Pamenecellulosepalokha ndi polima zachilengedwe, anthu apanga njira zosinthira ndikuzigwiritsa ntchito m'njira zosiyanasiyana. Mwachitsanzo, mankhwala amatha kusintha mawonekedwe ake kuti akhale oyenera kugwiritsidwa ntchito mwapadera. Komabe, ngakhale atasinthidwa, cellulose imakhalabe ndi chiyambi chake, ndikupangitsa kuti ikhale yosunthika komanso yamtengo wapatali muzochitika zachilengedwe komanso zopangidwa.
