Chifukwa chiyani cellulose imatchedwa polymer?

Te cellulose, nthawi zambiri amatchedwa mankhwala ochuluka kwambiri padziko lapansi, ndi molekyulu yosangalatsa komanso yovuta kwambiri yokhudza mbali zosiyanasiyana za moyo, kuyambira pa kapangidwe ka mbewu popanga mapepala ndi ziwalo.

Kumvetsetsa chifukwaleraImatchulidwa ngati polymer, ndikofunikira kuti musangalale ndi mawonekedwe ake, zojambula zake, ndi machitidwe omwe amawonetsa ku macroscopic ndi microscopic. Mwa kupenda mbali zonsezi, titha kuyimitsa chikhalidwe cha polima cha cellulose.

POLYMER TORICICICES:
Polity sayansi ndi nthambi ya ulaliki yomwe imakhudzana ndikuphunzira ma macromorolecles, omwe ndi mamolekyu akuluakulu opangidwa kuti abwerere magawo obwereza omwe amadziwika kuti monomers. Njira ya polymerization imaphatikizapo kugwirizanitsa kwa iwo omwe ali ndi zomangirazi, ndikupanga maunyolo kapena ma network.

Cellulose molecular:
Cellulose makamaka ndi kaboni, haidrojeni, ndi maatomu a okosijeni, adakonzedwa mu kapangidwe ka mzere wofanana ndi mzere. Chomanga chake choyambirira, molekyulu ya glucose, imakhala gawo la monomeric ya ma cellulose polymerization. Chipinda chilichonse cha glucose mkati mwa telotose chimalumikizidwa ndi kudzera pa Via (1 → 4) Magulu a glucose (-oh)

Chikhalidwe cha Polymeric of Cellulose:

Kubwereza mayunitsi: The β (1 → 4) Kulumikizana kwa Glycosidic mu Cellulose pobwereza mayunitsi a glucose pamodzi. Kubwereza kumeneku ndi mawonekedwe ofunikira a polima.
Kulemera kwambiri molecular: mamolekyulu okwera masentimita zikwizikwi kwa mazana mamiliyoni a ma unitsi a glucose, zomwe zimayambitsa zolemera zapamwamba kwambiri za zinthu za polymer.
Kapangidwe kakang'ono kwambiri: makonzedwe a mayunitsi a glucose m'matumbo amapanga ma unyolo, opangidwa ndi magulu ofanana ndi a polima.
Kuyanjana kwa pakati: ma molekyulu owonetsera celluulose omwe ali ndi maunyolo oyandikana nawo, adatsogolera mapangidwe a microfibrils ndi ma mucroscopic.
Makina katundu: Mphamvu yamakina komanso yolimba ya cellulose, yofunika chifukwa cha kukhulupirika kwa cell kubzala, zimadziwika ndi chikhalidwe chake cha polymer. Izi zikuthandizani kwa zida zina za polymer.
Zoyenda: Ngakhale kuti anali wamphamvu, cellose ndi kuwonongeka kwa ma cell, omwe hydrolyze kulumikizana kwa glucose pakati pa malo owonera bwino.

Mapulogalamu ndi Kufunika:
Chilengedwe cha polymer chaleraAmayang'anitsitsa ntchito zosiyanasiyana pamakampani osiyanasiyana, kuphatikiza pepala ndi zamkati, zolembedwa, mankhwala opangira mankhwala, komanso mphamvu zobwezeretsanso. Zipangizo zochokera ku Cellulose ndizofunika kwambiri, kusinthika, kusinthika, komanso kusinthasintha, kuwapangitsa kukhala koyenera kwambiri m'dziko lamakono.

Ma cellulose amayenerera ngati polymer chifukwa cha kapangidwe kake, womwe umakhala ndi zingwe za shuga wolumikizidwa ndi β (1 → 4) zomangira zazitali, zomwe zimapangitsa ma unyolo akuluakulu. Chikhalidwe chake cha polymer chimawonekera mumikhalidwe yosiyanasiyana, kuphatikiza mapangidwe a masenteli owonjezereka, kusanjana kwanthawiyo, makina opanga, komanso malo osakwanira. Kumvetsetsa kwa Cellulose monga polymer ndikopeka pogwiritsa ntchito mapulogalamu ake amisala komanso kukulitsa kuthekera kwake mwaluso ndi zida zokhazikika muukadaulo wokhazikika.
