Kodi cellulose ndi polima yachilengedwe kapena yopangidwa?

Selosindi polima wachilengedwe, chinthu chofunikira kwambiri pa makoma a maselo m'zomera. Ndi chimodzi mwa zinthu zachilengedwe zambiri padziko lapansi ndipo chimagwira ntchito ngati zinthu zomangira zomera. Tikamaganizira za cellulose, nthawi zambiri timaigwirizanitsa ndi kupezeka kwake mu matabwa, thonje, mapepala, ndi zinthu zina zosiyanasiyana zochokera ku zomera.

Kapangidwe ka cellulose kamakhala ndi maunyolo ataliatali a mamolekyu a shuga olumikizidwa pamodzi kudzera mu ma bond a beta-1,4-glycosidic. Maunyolo awa amakonzedwa mwanjira yomwe imawalola kupanga mapangidwe olimba komanso a ulusi. Kapangidwe kapadera ka maunyolo awa kamapatsa cellulose mphamvu zake zodabwitsa zamakaniko, zomwe zimapangitsa kuti ikhale gawo lofunikira popereka chithandizo cha kapangidwe ka zomera.

Njira yopangira cellulose mkati mwa zomera imaphatikizapo enzyme ya cellulose synthase, yomwe imapanga polymer ya mamolekyu a shuga kukhala maunyolo ataliatali ndikuwatulutsa mu khoma la selo. Njirayi imachitika m'mitundu yosiyanasiyana ya maselo a zomera, zomwe zimathandiza kuti minofu ya zomera ikhale yolimba komanso yolimba.

Chifukwa cha kuchuluka kwake komanso mawonekedwe ake apadera, cellulose yagwiritsidwa ntchito m'njira zambiri kupatula ntchito yake mu zamoyo za zomera. Makampani amagwiritsa ntchito cellulose popanga mapepala, nsalu (monga thonje), ndi mitundu ina ya mafuta achilengedwe. Kuphatikiza apo, zinthu zochokera ku cellulose monga cellulose acetate ndi cellulose ethers zimagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo mankhwala, zowonjezera zakudya, ndi zokutira.

PameneselulosiNgakhale kuti ndi polima yachilengedwe, anthu apanga njira zosinthira ndikugwiritsa ntchito m'njira zosiyanasiyana. Mwachitsanzo, mankhwala a mankhwala amatha kusintha mawonekedwe ake kuti akhale oyenera kugwiritsidwa ntchito mwanjira inayake. Komabe, ngakhale m'njira zosinthidwa, cellulose imasunga chiyambi chake chachilengedwe, zomwe zimapangitsa kuti ikhale chinthu chogwiritsidwa ntchito mosiyanasiyana komanso chamtengo wapatali m'malo achilengedwe komanso opangidwa ndi akatswiri.
