Kutheni le iselcelose ibizwa ngokuba yiPolymer?

I-SellUlose, idla ngokubhekiswa kuyo njengeyona nto ibalulekileyo emhlabeni, yimolekyuli enomdla kwaye iyimpembelelo enzulu kwiinkalo ezahlukeneyo zobomi, ivela kubume bezityalo ekwenzeni amaphepha kunye nezixhobo.

Ukuqonda ukuba kutheniiselluloseIhlelwe njenge-polymer, kubalulekile ukuba ube nokuqulunqa kubume bayo bokwakhiwa, iipropathi zesakhiwo, kunye nokuziphatha okubonisa amanqanaba amaMacroscopic nakwimicroscopic. Ngokuvavanya le miba ngokugqibeleleyo, sinokuyiqonda i-polymer yobume be-sellyulose.

I-polymer chemistrys
I-Polymer yeSayensi lisebe le-chemistry elijongana nophando lweMacromolecules, eziziimolekyuli ezinkulu ezithambekele ukuphinda i-monomes. Inkqubo ye-polymerizazation ibandakanya ukubophala kwezi moto ngokusebenzisa iibhondi ezinamachaphaza, ukwenza amakhonkco omde okanye iinethiwekhi.

Imo yemolekyuli ye-selselose:
I-seluplose iqulunqwe ngekhabhoni, i-hydrogen, kunye neeathom zeoksijini, zilungelelaniswe kwi-coctory yekhonkco. Ibhloko yaso yesakhiwo, imolekyuli yeglucose, isebenza njengeyunithi ye-monomeric ye-sellulose polymerization. Iyunithi nganye ye-glucose ngaphakathi kwi-selselose chain iqhagamshelwe kwi-β (1 → 4) I-Glycosidi Corvices, apho i-Hydroxyl (-4 yee-Hydbon-4 yeeYunithi ze-Glucose ze-gebos.

I-polymeric uhlobo lwe-sellyulose:

Iiyunithi zokuphinda: 1 β (1 → 4) I-Glycosidi inxibelelana ne-sellulose Playttition ye-Glucose Tain. Oku kuphindaphindeka kweeyunithi zolwakhiwo luphawu olusisiseko lwee-polymers.
Ubunzima obuphezulu bemolekyuli: Iimolekyuli zeselselose zibandakanya amawaka kwizigidi zeeyunithi zeGlucose, ezikhokelela kwimilinganiselo ephezulu yemolekyuli eqhelekileyo yezinto zePolymer.
Isakhiwo seChain Chain
Ukudibana kwe-Intermolecular: I-seluplose Molecules Invelogy Hydrogen Hydrogen Howning phakathi kwee-chain ezikufuphi, ziququzelela ukwakhiwa kwee-microfibrils kunye nezakhiwo ze-macroscopic, ezinje ngee-fibers zesellulose.
Iipropathi zoomatshini: amandla omatshini kunye nobunkunkqele beselselose, kubalulekile kwingqibelelo yeselfowuni yezityalo, zichazwe kwindalo yayo yePolymer. Ezi ndawo zikhusela ezinye izinto zePolymer.
Biodegradability: Despite its robustness, cellulose is biodegradable, undergoing enzymatic degradation by cellulases, which hydrolyze the glycosidic linkages between glucose units, ultimately breaking down the polymer into its constituent monomers.

Izicelo kunye nokubaluleka:
Imo yePolymer yeiselluloseI-pultins isebenza kwizicelo zayo ezahlukeneyo kumashishini ahlukeneyo, kubandakanya nePhepha kunye nePubp, amaNqaku, amaNyanga, kunye namandla ahlaziyiweyo. Izinto ezisekwe kwi-selsulose zixabisa indyebo yabo, ukuvuselelwa, ukuvuselelwa, kunye nokuziguquguquka, zibenza babe nokungabonakali koluntu.

I-selsulose ifanelekile njenge-polymer ngenxa yesakhiwo sayo semolekyuli, equlathe i-β (1 → 4) i-Glycosidic, ikhokelela kwimilinganiselo ephezulu yemolekyuli. Indalo yayo yePolymer ibonakala kwiimpawu ezahlukeneyo, kubandakanya ukwakhiwa kweemolekyuli ezandisiweyo, ukusebenzisana kwe-intermolecular, iipropathi zoomatshini, kunye ne-biodegradiance. Ukuqonda ukuba i-sellulose njenge-polymer yinto ebalulekileyo yokuxhaphaza izicelo zayo ezizinzileyo kunye nokusebenzisa amandla ayo kwiitekhnoloji nezixhobo.
