I-Celluloseiyingxenye eyinhloko yezindonga zamangqamuzana ezitshalo, futhi iyi-polysaccharide esatshalaliswa kakhulu futhi eningi kakhulu ngokwemvelo, ibalwa ngaphezu kuka-50% wekhabhoni etholakala endaweni yezitshalo. Phakathi kwazo, okuqukethwe kwe-cellulose ukotini kusondele ku-100%, okuwumthombo ohlanzekile we-cellulose wemvelo. Ngokhuni jikelele, i-cellulose i-akhawunti ye-40-50%, futhi kukhona i-10-30% ye-hemicellulose kanye ne-20-30% ye-lignin. I-Cellulose ether yitemu elivamile lezinhlobonhlobo zokuphuma kokunye okutholwe ku-cellulose yemvelo njengento eluhlaza ngokufakwa kwe-etherification. Kungumkhiqizo owenziwe ngemuva kokuthi amaqembu e-hydroxyl ku-cellulose macromolecules eshintshwe kancane noma ngokuphelele ngamaqembu e-ether. Kukhona i-intra-chain kanye ne-inter-chain hydrogen bond ku-cellulose macromolecules, okunzima ukuncibilika emanzini kanye cishe nawo wonke ama-solvents e-organic, kodwa ngemva kwe-etherification, ukwethulwa kwamaqembu e-ether kungathuthukisa i-hydrophilicity futhi kwandise kakhulu ukuncibilika emanzini kanye nezinyibilikitsi eziphilayo. Izakhiwo ze-Solubility.
I-cellulose ether inegama elithi "industrial monosodium glutamate". Inezici ezinhle kakhulu ezifana nokuqina kwesixazululo, ukuncibilika kahle kwamanzi, ukumiswa noma ukuzinza kwe-latex, ukwakheka kwefilimu, ukugcinwa kwamanzi, nokunamathela. Ayinabuthi futhi ayinambitheki, futhi isetshenziswa kakhulu ezintweni zokwakha, imithi, ukudla, izindwangu, amakhemikhali ansuku zonke, ukuhlola kwe-petroleum, izimayini, ukwenza amaphepha, i-polymerization, i-aerospace kanye neminye imikhakha eminingi. I-Cellulose ether inezinzuzo zokusetshenziswa okubanzi, ukusetshenziswa kweyunithi encane, umphumela omuhle wokuguqula, kanye nobungane bemvelo. Ingathuthukisa kakhulu futhi ithuthukise ukusebenza komkhiqizo emkhakheni wokwengezwa kwawo, okulungele ukuthuthukisa ukusebenza kahle kokusetshenziswa kwezinsiza kanye nenani elengeziwe lomkhiqizo. Izithasiselo ezinobungani kwemvelo ezibalulekile emikhakheni ehlukahlukene.
Ngokusho kwe-ionization ye-cellulose ether, uhlobo lwama-substituent kanye nomehluko ekuncibilikeni, i-cellulose ether ingahlukaniswa ngezigaba ezahlukene. Ngokuya ngezinhlobo ezahlukene zama-substitutes, ama-cellulose ether angahlukaniswa abe ama-ether awodwa nama-ether axutshiwe. Ngokuvumelana ne-solubility, i-cellulose ether ingahlukaniswa ngemikhiqizo engancibiliki emanzini futhi engancibiliki emanzini. Ngokusho kwe-ionization, ingahlukaniswa nge-ionic, i-non-ionic kanye nemikhiqizo exubile. Phakathi kwama-ether e-cellulose ancibilikayo emanzini, ama-ether e-cellulose angewona ama-ionic afana ne-HPMC anokumelana nezinga lokushisa okungcono kakhulu kanye nokumelana nosawoti kune-ionic cellulose ethers (CMC).
Ithuthuka kanjani i-cellulose ether embonini?
I-cellulose ether yenziwa kusukela kukotini ocolisisiwe ngokusebenzisa i-alkalization, i-etherification nezinye izinyathelo. Inqubo yokukhiqiza yebanga lezemithi i-HPMC kanye nebanga lokudla i-HPMC iyafana. Uma kuqhathaniswa ne-ether ye-cellulose ether yokwakha, inqubo yokukhiqiza ye-HPMC ye-pharmaceutical-grade kanye ne-HPMC yebanga lokudla idinga i-etherification ehleliwe, eyinkimbinkimbi, enzima ukulawula inqubo yokukhiqiza, futhi idinga ukuhlanzeka okuphezulu kwemishini kanye nendawo yokukhiqiza.
Ngokusho kwedatha ehlinzekwe yi-China Cellulose Industry Association, inani lokukhiqiza eliphelele labakhiqizi be-cellulose ether abangewona i-ionic abanomthamo omkhulu wokukhiqiza wasekhaya, njenge-Hercules Temple, i-Shandong Heda, njll., idlula i-50% yenani eliphelele lokukhiqiza likazwelonke. Kunabanye abakhiqizi be-ether abaningi abancane abangewona ionic cellulose abanamandla okukhiqiza angaphansi kwamathani angu-4,000. Ngaphandle kwamabhizinisi ambalwa, iningi lawo likhiqiza ama-cellulose ether esezingeni lezinto zokwakha ajwayelekile, anenani eliphelele lokukhiqiza elingamathani ayi-100,000 ngonyaka. Ngenxa yokuntuleka kwamandla ezimali, amabhizinisi amaningi amancane ahluleka ukuhlangabezana namazinga ekutshalweni kwezimali kokuvikelwa kwemvelo ekuhlanzeni amanzi kanye nokukhipha igesi yokuhlanza ukuze kwehliswe izindleko zokukhiqiza. Njengoba izwe kanye nomphakathi wonke ubheka kakhulu ukuvikelwa kwemvelo, lawo mabhizinisi embonini angakwazi ukuhlangabezana nezidingo zokuvikelwa kwemvelo azovala kancane kancane noma anciphise ukukhiqizwa. Ngaleso sikhathi, imboni yokukhiqiza i-cellulose ether yezwe lami izokwanda nakakhulu.
Izinqubomgomo zasekhaya zokuvikela imvelo ziya ngokuya ziba namandla, futhi kubekwa izidingo eziqinile zobuchwepheshe bokuvikela imvelo kanye nokutshalwa kwezimali ohlelweni lokukhiqiza.i-cellulose ether. Izinyathelo ezisezingeni eliphezulu zokuvikela imvelo zandisa izindleko zokukhiqiza zamabhizinisi futhi zakha umkhawulo ophezulu wokuvikelwa kwemvelo. Amabhizinisi angakwazi ukuhlangabezana nezimfuneko zokuvikelwa kwemvelo cishe azovalwa kancane kancane noma ehlise umkhiqizo ngenxa yokwehluleka ukuhlangabezana namazinga okuvikela imvelo. Ngokusho kwe-prospectus yenkampani, amabhizinisi anciphisa kancane kancane ukukhiqiza futhi amise ukukhiqizwa ngenxa yezinto zokuvikela imvelo angase afake ukunikezwa okuphelele okungamathani angu-30,000/ngonyaka wezinto zokwakha ezivamile zebanga le-cellulose ether, elisiza ekwandiseni amabhizinisi anenzuzo.
Ngokusekelwe ku-cellulose ether, iyaqhubeka inwebela emikhiqizweni ephezulu kanye nephezulu ye-value-added
