Ukuqulunqwa kwezinto ezingafunekiyo zezityalo

Zininzi iintlobo zezixhobo zobukhulu bezityalo, kodwa ukwakhiwa kwabo okusisiseko kunomehluko omncinci, ubukhulu becala uqhutywa yiswekile kwaye ingenziswe iswekile.

. Izinto ezahlukeneyo zezityalo eziluhlaza zinemigangatho eyahlukeneyo yecandelo ngalinye. Oku kulandelayo kwazisa izinto ezintathu eziphambili zezixhobo zobukhulu bezityalo:

I-Selesese Ether, i-LEGIN kunye neHEMIIOSE.

1.3 Ukuqulunqwa okusisiseko kwezinto zezityalo eziluhlaza

1.3.1.1 Iseluplose

I-seluplose yi-macromolecular polysaccharide edityaniswe nge-D-glucose ene-β-1,4 Glycosidic Bonds. Yeyona mdala kwaye ininzi emhlabeni.

I-polymer yendalo. Isakhiwo semichiza sayo sidla ngokumelwa yifomula ye-Haworth Stosula kunye nefomyula yesihlalo esisihlalo, apho i-N Inqanaba le-Polysaccharide Polymeride.

1.3.1.2 I-LINGIN

Iyunithi esisiseko ye-LIGYIN yi-phenylpropane, edityaniswe nge-CC Binds kunye ne-ether.

Chwetheza i-polymer. Kwisakhiwo sezityalo, umaleko we-interchellillar iqulethe eyona ilokhwe,

Umxholo we-intracellilla wancipha, kodwa umxholo we-LINGIN wanda kwi-Inrider yodonga lwesibini. Njengempahla ye-intercellillar, i-LINGIN kunye ne-hemifibrils

Ngokudibeneyo bagcwalisa phakathi kweentsomi ezintle zodonga oluhle, ngaloo ndlela ukomeleza udonga lweselfowuni zeziqhamo zezityalo.

1.5 I-LINGIN YOKUGQIBELA YOKUGQIBELA, NGE: P-HYDDROXYylPOLLOLLPOLLOLLPOLLE, Guaiaiaiancy Propane, Syringyl Propane kunye ne-Reisdyl Utywala

1.3.1.3 HEMicellulose

Ngokungafaniyo ne-LINGIN, i-hemicellulose yi-heteropolymer equlathe iintlobo ezahlukeneyo ze-monosaccharides. Ngokwa kwezi

Iindidi zeswekile kunye nobukho bamaqela e-Acyl zinokwahlulwa zibe yiGlucomannan, i-Arabinosyl (i-4-o-i-o-methylgluusth) -Xylan,

I-4-E-methylgluusth xotun, iArabinosyl Galactan, njlnjl.

Iipesenti ezingamashumi amahlanu ze-tissue yenkuni yi-Xylan, ethintelayo kwii-microfibribs zeselfowuni kwaye zidityaniswe neentsinga.

Benza uthungelwano lweeseli ezinxulumene ngokuqinileyo omnye komnye.

1.4 Injongo yophando, ukubaluleka kunye nomxholo ophambili wesihloko

1.4.1 Injongo kunye nokubaluleka koPhando

Injongo yolu phando kukukhetha iintlobo ezintathu zokumelwa ngokusetyenziswa kwamacandelo ezinto zezixhobo eziluhlaza.

I-seluplose ikhutshwe kwizinto zezityalo. Khetha iarhente eqinisekisiweyo efanelekileyo, kwaye isebenzise i-selsulose ekhutshiweyo ukuba ithathe indawo yomqhaphu ukuba ifune kwaye iguqulwe i-fiber.

I-Vitamin Hether. I-ether elungiselelwe i-Seleupese yasetyenziswa kwiPrint Rective Primen, kwaye ekugqibeleni isiphumo sokuprinta sifakiwe nokufumanisa ngakumbi

I-seluplose ebhaka kwi-Dye yokuPrinta.

Okokuqala, uphando kwesi sihloko luye lwasombulula ingxaki yokufumana kwakhona kunye nokungcoliseka kwendalo esisityalo senkunkuma kwindawo ethile.

Kwangelo xesha, kwavela indlela entsha kumthombo weselselose. Okwesibini, i-Slodium engatyheliyo ye-chirroucetate kwaye i-2-Chloroeethanol isetyenziswa njengabameli,

Endaweni ye-chlorocetic ecekecekileyo yetyhefu, i-seluplose i-ether ilungiselelwe kwaye ifakwe kwi-Cotton Ilaphu le-Dye Printa iDye, kunye neSodium

Uphando malunga nokubambela lunenqanaba elithile lesikhokelo, kwaye lube nokubaluleka okuqinisekileyo kunye nexabiso lokubonisa.

1.4.2 Umxholo wophando

1.4.2.1 Ukukhutshwa kwesellulose ukusuka kwizityalo eziluhlaza

Okokuqala, amacandelo ezilwanyana ezizityalo eziluhlaza alinganiswe kwaye ahlalutywe, kwaye izinto ezintathu zokubonisa zikhethwe ukukhupha i-fiber.

Iivithamini. Emva koko, inkqubo yokukhupha isellulose yayenzelwe ukuba kuphathwa kakuhle kweAlkali ne-Acid. Ekugqibeleni, uv

I-Sperption Specturoscopy, i-ftr kunye ne-XRR yayisetyenziselwa ukuhambisa iimveliso.

1.4.2.2.2.2.2.2.2.2 Ulungiselelo lwe-seluplose

Sebenzisa i-pine will seluplose njengezixhobo eziluhlaza, kwagqitywa i-alkali egxininisiweyo, kwaye emva koko kwenziwa uvavanyo lwe-orthogonal kwaye isetyenzisiwe enye,

Iinkqubo zokuLungiselela ze-CMC, i-hec kunye ne-hecmc zaye zalungiselela ngokulandelelana.

I-selsulose elungiselelwe i-Selet ibonakaliswa ngu-fir, i-H-NMR kunye ne-XRR.

1.4.2.3 Ukusetyenziswa kwe-selsulose ether paste

Iintlobo ezintathu ze-Selessese Talupen kunye neSodium Allium yasetyenziswa njengeepeyinti zentsusa, kunye nenqanaba lokulinganisa amachiza, umthamo wokuqulunqa kwamanzi kunye nokuhambelana kweekhemikhali ze-pastem zantlandlolo zavavanywa.

Iipropati ezisisiseko ze-pastes ezine zaza zathelekiswa nentlonipho kwiipropathi kunye nokugcinwa kokugcina.

Sebenzisa iintlobo ezintathu ze-Selessulose enina kunye ne-sodium engaqhelekanga njenge-Continal yoqobo, cwangcisa i-Depring Passing Plasta, qhuba i-Dye Printration, Dlulisa itafile yovavanyo

Thelekisa ezintathuI-seluplosekwaye

Iipropathi zokuprinta ze-sodium ye-sodium.

1.4.3 Amanqaku oPhando oluNtu

.

Indlela entsha, kwaye kwangaxeshanye, ukuya kuthi ga kwinqanaba elithile, isombulula ingxaki yokuphinda isebenze ngezinto eziluhlaza zenkunkuma kunye nongcoliseko lwendalo; kwaye iphucula i-fiber

Indlela yokukhupha.

.

Umhlaza), njl. Njl. Ziyingozi kakhulu emzimbeni womntu kunye nokusingqongileyo. Kweli phepha, i-chiroum ye-thelorocetate enobuhlobo kwindalo kwaye i-2-chloroethanol isetyenziswa njengabameli boqeqesho.

Endaweni ye-chlorocetic acid kunye ne-Ethylene oxide, iseluplose eule ilungisiwe. .
