izinto zokusetshenziswa eziphambili ezidingekayo ekukhiqizweni kweI-Cellulose EtherFaka phakathi ukotini ocwengekile (noma i-soni le-solp) namanye amakhemikhali ajwayelekile, njenge-propelene oxide, i-methyl chloride, uketshezi we-caustic soda, i-caustic soda, i-ethylene oxide, i-toluene nezinye izinto ezishubile. Amabhizinisi aphezulu embonini wale mboni afaka ukotini ocwengekile, amabhizinisi okukhiqiza amakhemikhali izinkuni namanye amabhizinisi amakhemikhali. Ukuguquguquka kwentengo kwezinto zokusetshenziswa eziphambili ezingenhla zizoba namazinga ahlukahlukene omthelela ezindlekweni zokukhiqiza kanye nokuthengisa inani lentengo ye-cellulose ether.
Izindleko zekotoni elicwengiwe ziphakeme kakhulu. Ukuthatha Ukwakha Ibanga le-Cellulose Ether Njengesibonelo, Ngesikhathi sokubika, izindleko zokotini ezicwengiwe zibalelwa kuma-31.74%, 28.59% wezindleko zokuthengisa zeBali le-Cellule Cellule Cellulose Cellulose. Ukuguquguquka kwentengo kakotoni okucwengiwe kuzothinta izindleko zokukhiqiza ze-cellulose ether. Izinto eziphambili ezingavuthiwe zokukhiqizwa ukotini ocwengezelayo kungamabutho ekotini. Ama-Cotton Linters angomunye wemikhiqizo eyenziwe yinqubo yokukhiqiza ukotini, ikakhulukazi esetshenziselwa ukukhiqiza i-pulp yekotini, ukotini ocwengekile, i-nitrocellulose kanye neminye imikhiqizo. Inani lokusebenzisa kanye nokusetshenziswa kwama-cotton linters kanye nokotini kuhluke kakhulu, futhi intengo yalo ngokusobala iphansi kunaleyo kakotini, kepha inokuhlotshiswa okuthile ngokushintshashintsha kwentengo kakotini. Ukushintshashintsha kwentengo entengo kakotini kuthinta intengo kakotini ecwengekile.
Ukushintshashintsha okubukhali ngentengo kakotini okucwengiwe kuzoba namazinga ahlukene omthelela ekuphathweni kwezindleko zokukhiqiza, izintengo zomkhiqizo kanye nenzuzo yamabhizinisi. Lapho intengo kakotini ecwengekile iphakeme futhi intengo ye-wood pulp ishibhile, ukuze inciphise izindleko, i-sonip pulp ingasetshenziswa njenge-sublivent kanye nesengezo sokotini ocwengekile, ikakhulukazi ukukhiqizwa kwe-Cellulose Afeskuthaka okufana Ibanga lezemithi nelokudlaI-Cellulose Afers. Ngokwemininingwane evela kuwebhusayithi ye-National Bureau of Statistics, ngonyaka ka-2013, indawo yokutshala ukotini yezwe lami kwakungamahektha ayizigidi ezingama-4,35, kanti umphumela wekotoni kazwelonke wawungamathani ayizigidi ezingama-6.31. Ngokusho kwezibalo ezivela e-China Cellulose Industry Association, ngo-2014, okuphelele kokukhishwa ukotini okucwengiwe okukhiqizwa ngabakhiqizi bekotini abacwebezelayo abacwengiwe amathani angama-332,000, futhi ukuhlinzekwa kwezinto ezingavuthiwe kuningi.
Izinto zokusetshenziswa eziphambili zokukhiqizwa kwemishini yamakhemikhali we-graphite ziyinsimbi kanye ne-graphite carbon. Intengo yensimbi kanye ne-graphite carbon account yesilinganiso esiphakeme kakhulu sezindleko zokukhiqiza zemishini yamakhemikhali ye-graphite. Ukushintshashintsha kwamanani kwalezi zinto ezingavuthiwe kuzoba nomthelela othile kwizindleko zokukhiqiza kanye nokuthengisa inani lentengo yemishini yamakhemikhali.
