I-Cellulosics ibhekisela kwiqela lezinto ezithathwe kwi-cellulose, eyona nto ininzi i-polymer yezinto eziphilayo emhlabeni kunye nenxalenye enkulu yeendonga zeeseli zesityalo. I-Cellulose yi-polysaccharide yomgca ehlanganiswe ngokuphindaphindiweyo kweeyunithi ze-glucose ezidityaniswe kunye ne-β (1→ 4) iibhondi ze-glycosidic.

Izinto zeCellulozic zinokuhlelwa ngokubanzi zibe ngamacandelo amabini: ezendalo kunye nezokwenziwa.

IiSelulosis zendalo:

1. I-Wood Pulp: Iphuma kwimicu yomthi, i-pulp yomthi ngumthombo oyintloko we-cellulose esetyenziswa kumashishini ahlukeneyo, kuquka ukwenza iphepha, iingubo kunye nokwakhiwa.
2. Umqhaphu: Imisonto yomqhaphu, efunyenwe kwimbewu yembewu yesityalo somqhaphu, iquka icellulose yonke. Umqhaphu usetyenziswa kakhulu kwimveliso yelaphu ngenxa yokuthamba kwayo, ukuphefumla kwayo, kunye ne-absorbency.
3. IHemp: Imicu yeHemp, ethathwe kwizikhondo zesityalo sehemp, ineselulosi kwaye isetyenziswa kwilaphu, ukwenza iphepha, kunye nemathiriyeli edibeneyo.
4. I-bamboo: Iintsinga ze-bamboo, ezithathwe kwi-pulp yezityalo ze-bamboo, zityebile kwi-cellulose kwaye ziqeshwe kwimveliso yempahla, kunye nokuveliswa kwephepha kunye nezixhobo zokwakha.

IiSelulosis zokwenziwa:

1. I-Cellulose ehlaziyiweyo: Iveliswa ngokuchithwa kwe-cellulose kwi-solvent, njenge-curammonium hydroxide okanye i-viscose, ilandelwa yi-extrusion kwi-bath coagulation. Izinto ezenziwe ngokutsha ze-cellulose ziquka i-viscose rayon, i-lyocell (i-Tencel), kunye ne-cellulose acetate.
2. I-Cellulose Esters: Izinto eziphuma kwi-cellulose eziguqulwe ngokwekhemikhali ezifunyenwe ngokusabela kwe-esterification ngee-asidi ezahlukeneyo. I-cellulose esters eqhelekileyo iquka i-cellulose acetate, i-cellulose nitrate (i-celluloid), kunye ne-cellulose acetate butyrate. Ezi zixhobo zifumana izicelo kwimveliso yefilimu, iingubo kunye neeplastiki.

Ukusetyenziswa kweeSelulosis:

1. Ilaphu: Iintsinga zeCelulosic, zombini zendalo (umzekelo, umqhaphu, ihempe) kunye neziveliswa ngokutsha (umzekelo, i-viscose rayon, i-lyocell), zisetyenziswa kakhulu ekwenzeni amalaphu empahla, amalaphu asekhaya, kunye namalaphu emizi-mveliso.
2. Iphepha kunye nokuPakisha: I-pulp yokhuni, ephuma kwimithombo ye-cellulosic, isebenza njengeyona nto iphambili ekrwada yokwenza iphepha kunye nezinto zokupakisha. Iifiber zeCellulos zinika amandla, i-absorbency, kunye nokuprintwa kwiimveliso zephepha.
3. Izixhobo zokwakha: Iimathiriyeli zeseli, ezifana nemithi kunye ne-bamboo, zisetyenziselwa ulwakhiwo lwamalungu olwakhiwo (umzekelo, ukucandwa kwamaplanga, iplywood) kunye nokugqitywa kokuhombisa (umzekelo, umgangatho oqinileyo, iipaneli ze-bamboo).
4. Iimveliso zoNonophelo zoMntu: Izinto ezisekelwe kwi-cellulose ziqeshwe kwiimveliso zokunyamekela komntu, kubandakanywa ukusula, izicubu, kunye neemveliso zokucoceka ezithathayo, ngenxa yokuthamba, amandla kunye nokubola.
5. Ukutya kunye neMichiza: I-cellulose derivatives, efana ne-microcrystalline cellulose kunye ne-carboxymethylcellulose, isetyenziswe njengezinto ezincedisayo ekutyeni nasekuxutyweni kwamachiza ngenxa yokuqina, ukuzinzisa kunye nokubopha iipropati.

Izinto eziluncedo kwiCellulosis:

1. I-Renewable kunye ne-Biodegradable: Izixhobo ze-cellulosic zithathwe kwimithombo yezityalo ezihlaziyiweyo kwaye ziyakwazi ukubola, zizenza ezinye iindlela ezizinzileyo zokusingqongileyo kwiipolymers zokwenziwa.
2. I-Versatility: I-Cellulosic ibonisa uluhlu olubanzi lweepropathi kunye nokusebenza, ivumela usetyenziso olwahlukeneyo kuwo wonke amashishini, ukusuka kwizinto ezilukiweyo ukuya kumayeza.
3. Ukufumaneka: I-Cellulose ininzi kwindalo, kunye nemithombo evela kwimithi kunye nekotoni ukuya kwi-bamboo kunye ne-hemp, iqinisekisa ukubonelela okuhambelanayo nokuthembekileyo kusetyenziso lwemizi-mveliso.
4. I-Biocompatibility: Izinto ezininzi ze-cellulosic zihambelana ne-biocompatible kwaye aziyiyo ityhefu, zizenza zilungele ukusetyenziswa ekutyeni, kumayeza, nakwizicelo zonyango.

Isishwankathelo, i-cellulosics ibandakanya uluhlu olwahlukeneyo lwezixhobo ezivela kwiselulosi, ezibonelela ngezinto ezininzi, uzinzo, kunye nokuhambelana kwebhayoloji kuluhlu olubanzi lwezicelo kumashishini afana nelaphu, ukwenza iphepha, ukwakhiwa, ukhathalelo lomntu, kunye nokhathalelo lwempilo.
