Kungani i-cellulose ibizwa nge-polymer?

I-Cellulose, evame ukubizwa ngokuthi i-organic accound eningi kunazo zonke emhlabeni, i-molecule ekhangayo futhi eyinkimbinkimbi enomthelela omkhulu ezicini ezahlukahlukene zokuphila, ezisukela ekwakhekeni kwezitshalo ephepheni.

Ukuqonda ukuthi kunganicelluloseIhlukaniswe njenge-polymer, kubalulekile ukudlulela ekwakhekeni kwamangqamuzana, izakhiwo ezakhiwo, kanye nokuziphatha okubonisa emazingeni akwaMacroscopic kanye nama-microscopic. Ngokuhlola lezi zinto eziphelele, singacacisa uhlobo lwe-polymer lwe-cellulose.

Isisekelo se-Polymer Chemistry:
Isayensi ye-Polymer yigatsha lamakhemikhali abhekene nocwaningo lwama-macromolecule, angama-molecule amakhulu akhiwa amayunithi aphindaphindwayo abizwa ngama-monomers. Inqubo ye-polymerization ifaka ubuhlobo balawa ma-monomers ngokusebenzisa izibopho ze-combared, akha amaketanga amade noma amanethiwekhi.

Isakhiwo se-Cellulose Molecular:
I-cellulose yakhiwa ngokuyinhloko ikhabhoni, ama-hydrogen, nama-athomu omoya-mpilo, ahlelwe ngesakhiwo esinjenge-linear chain. Ibhulokhi yalo eyisisekelo yokwakha, i-molecule kashukela, isebenza njengeyunithi ye-monomeric for cellulose polymerization. Iyunithi ngalinye le-glucose ngaphakathi kwe-cellulose chain lixhumeke kokulandelayo nge-β (1 → 4) Amaqembu e-glycosidic, lapho amaqembu we-puldroxyl (-oh) e-Carbon-1 ne-Carbon-4 ye-Carbose-1 ne-Carbon-4 esondelene ne-Clowlose actions ukuphendula.

Imvelo ye-polymeric ye-cellulose:

Ukuphindaphinda amayunithi: I-β (1 → 4) Ukuxhumana kwe-glycosidic emithonjeni ye-cellulose ekuphindwayo kwamayunithi we-glucose eceleni kwe-polymer chain. Lokhu kuphindaphinda kwamayunithi wesakhiwo kuyisici esiyisisekelo sama-polymers.
Isisindo esiphakeme samangqamuzana: ama-molecule aphezulu aqukethe izinkulungwane eziya ezigidini zama-glucose amayunithi, okuholela ezindweni eziphakeme zamangqamuzana ajwayelekile ezintweni ze-polymer.
Isakhiwo eside kaketanga: Ukuhlelwa komugqa kwama-glucose amayunithi eCellulose Chains kwanweba amaketanga ama-molekfor
Ukusebenzisana kwe-intermolecular: Ama-molecule we-cellulose ekhombisa ukubopha ama-hydrogen we-hydrogen phakathi kwamaketanga asondelene, okwenza ukwakheka kwama-microfibrils kanye nezakhiwo ze-macroscopic, njengezinsika ze-cellulose.
Izakhiwo zemishini: Amandla okwenziwa ngomshini kanye nokuqina kwe-cellulose, ebalulekile ekuthembekeni kwesakhiwo kwezindonga zezitshalo, kubangelwa imvelo yaso ye-polymer. Lezi zindawo zikhumbuza ezinye izinto ze-polymer.
I-Biodegradeabilibility: Yize i-Cellulose iyi-biodegyadable, ibhekana nokuwohloka kwe-enzymatic ngamaselula, ahlolwe ama-glycosidic ukuxhumana phakathi kwama-glucose amayunithi, ekugcineni abhidliza i-polymer emamonweni awo akhona.

Izicelo nokubaluleka:
Imvelo ye-polymer yecelluloseYehlisa izicelo zayo ezahlukahlukene kuyo yonke imboni ehlukahlukene, kufaka phakathi iphepha ne-pulp, izindwangu, amakhamisha, namandla avuselelekayo. Izinto zokwenziwa ezisekelwe ku-Cellulose ziyenziwa ngobuningi bazo, i-biodegradeability, ukuvuselelwa, kanye nokuguquguquka, kubenza babaluleke kakhulu emphakathini wanamuhla.

I-Cellulose ifanelwe njenge-polymer ngenxa yesakhiwo sayo samangqamuzana, esihlanganisa ama-glucose amayunithi axhumene no-β (1 → 4) amakhethini ama-glycosic, aphumela emaketangeni amade anezinsimbi eziphakeme. Imvelo yayo ye-polymer ibonakalisa ezicini ezahlukahlukene, kufaka phakathi ukwakheka kwamaketanga ama-molefanelar anwetshiwe, ukusebenzisana kwama-intermolecal, izakhiwo zemishini, kanye ne-biodergAdability. Ukuqonda i-cellulose njenge-polymer kuyinto ebaluleke kakhulu yokuxhaphaza izinhlelo zayo ze-MyRiad kanye nokuhlanganisa amathuba awo kubuchwepheshe obuzinzile nezinto zokwakha.
