Sei cellulose ichinzi polymer?

Cellulose, inowanzonzi chinhu chinowanikwa zvakanyanya pasi rose, imorekuru inonakidza uye yakaoma ine simba guru pamativi akasiyana-siyana ehupenyu, kubva pakugadzirwa kwemiti kusvika pakugadzirwa kwemapepa nemachira.

Kuti tinzwisise chikonzero neiseluloseYakarongwa sepolymer, zvakakosha kuti tiongorore kuumbwa kwayo kwemamorekuru, hunhu hwemaumbirwo ayo, uye maitiro ayo pamazinga ese ari maviri macroscopic uye microscopic. Nekuongorora zvinhu izvi zvizere, tinogona kujekesa hunhu hwepolymer hwecellulose.

Nheyo dzePolymer Chemistry:
Sainzi yePolymer ibazi rekemesitiri rinobata nekudzidza macromolecules, ayo ari mamorekuru makuru anoumbwa nemayuniti ezvimiro anodzokororwa anozivikanwa semamonomers. Maitiro epolymerization anosanganisira kubatana kwemamonomers aya kuburikidza nemabond ecovalent, achiumba cheni refu kana network.

Maumbirwo eMorekuru yeCellulose:
Cellulose inonyanya kuumbwa nemaatomu ekabhoni, hydrogen, uye okisijeni, akarongwa muchimiro chakafanana necheni. Chinhu chikuru chayo chekuvaka, molekyuru yeglucose, inoshanda seyuniti yemonomeric yepolymerization yecellulose. Yuniti yega yega yeglucose iri mukati meketani yecellulose yakabatana kune inotevera kuburikidza ne β(1→4) glycosidic linkages, uko mapoka e hydroxyl (-OH) ari pa carbon-1 ne carbon-4 emayuniti eglucose ari pedyo anosangana ne condensation reactions kuti agadzire linkage.

Hunhu hwePolymeric hweCellulose:

Zviyero Zvinodzokorora: Kubatana kwe β(1→4) glycosidic mu cellulose kunoita kuti zviyero zve glucose zvidzokororwe pamwe chete necheni ye polymer zvidzokororwe. Kudzokorora uku kwezvikamu zve structural hunhu hukuru hwema polymer.
Kurema Kwakawanda Kwemamorekuru: Mamorekuru ecellulose ane zviuru kusvika kumamiriyoni emayuniti eglucose, zvichiita kuti pave nehuremu hwakawanda hwemamorekuru hunowanzoitwa nezvinhu zvepolymer.
Maumbirwo eTende Refu: Kurongeka kwakarongeka kwemayuniti eglucose mumaketani ecellulose kunoumba macheni emolekyuli akatambanudzwa, akafanana nemaumbirwo akafanana necheni anoonekwa mumapolymers.
Kudyidzana Pakati peMamorekuru: Mamorekuru eCellulose anoratidza kubatana pakati pehydrogen pakati pemaketani ari pedyo, zvichiita kuti zvive nyore kuumbwa kwe microfibrils uye macroscopic structures, akadai se cellulose fibers.
Hunhu hweMuchina: Simba remuchina uye kuomarara kweselulosi, izvo zvakakosha pakuvaka madziro emasero emiti, zvinokonzerwa nehunhu hwayo hwepolymer. Hunhu uhwu hunoyeuchidza zvimwe zvinhu zvepolymer.
Kuora kwemuviri: Pasinei nekusimba kwayo, cellulose inogona kuora, ichiparadzwa ne enzymes ne cellulases, iyo inonyungudutsa glycosidic linkages pakati pe glucose units, zvichizopedzisira zvaputsa polymer kuita ma monomers ayo.

Mashandisirwo uye Kukosha:
Hunhu hwepolymerseluloseinotsigira mashandisirwo ayo akasiyana-siyana mumaindasitiri akasiyana-siyana, anosanganisira mapepa nepurasitiki, machira, mishonga, uye simba rinodzokororwa. Zvinhu zvakagadzirwa nesellulose zvinokosheswa nekuda kwekuwanda kwazvo, kuora, kugona kuvandudzwa, uye kushandiswa kwakasiyana-siyana, zvichiita kuti zvive zvakakosha munharaunda yemazuva ano.

Cellulose inokodzera kuva polymer nekuda kwechimiro chayo chemamorekuru, icho chine mayuniti eglucose anodzokororwa akabatana ne β(1→4) glycosidic bonds, zvichikonzera cheni refu dzine huremu hwakawanda hwemamorekuru. Hunhu hwayo hwepolymer hunoonekwa muhunhu hwakasiyana-siyana, kusanganisira kuumbwa kwecheni dzemamorekuru dzakareba, kudyidzana pakati pemamorekuru, hunhu hwemakanika, uye kuora kwehupenyu. Kunzwisisa cellulose sepolymer kwakakosha pakushandisa mashandisirwo ayo akawanda uye kushandisa kugona kwayo mune tekinoroji nezvinhu zvinogara kwenguva refu.
