I-Cellulose Afers, njengento ebalulekile ye-polymer, isetshenziswa kabanzi emasimini amaningi wezimboni. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ukuthuthukiswa kanye nokusetshenziswa kwe-cellulose, izithambiso kuye kwaba indlela yokucwaninga eshisayo. I-Cellulose Afers ayidlali nje kuphela iqhaza elibalulekile emikhakheni yendabuko efana nokwakha, amakhamishini, izimbobo, kanye namakhemikhali nsuku zonke, kepha futhi ikhombisa amandla aphezulu okuthola amasimu avelayo njengokudla nokuvikelwa kwemvelo.
1. Imiqondo eyisisekelo nezakhiwo ze-cellulose afes
I-Cellulose Afers yenziwa kusuka ku-cellulose yemvelo. Ngokuphendula kwe-etherification, amaqembu we-hydroxyl (-OH) kuma-molecule we-cellulose asabela ngama-ejenti aphenya ama-cellulose namaqembu ether (-O-). Abakwa-Collulose Bather Common BafakaI-methyl cellulose (MC), I-Hydroxyyethyl cellulose (HEC), I-Hydroxypropylllul (HPC)na-I-Hydroxypropyl methylcellulose (HPMC). Bane-solubility enhle yamanzi, ukuqina, ukuqina kanye nokuqina, ngakho-ke basetshenziswa kabanzi kwizimboni eziningi.

Imboni Yokwakha
Embonini yezokwakha, izithambiso ze-cellulose zisetshenziswa kakhulu njengabakhulu, ama-ejenti agcinwe amanzi kanye nama-bheology alawulayo ku-CEMM, ngodaka kanye nezimbobo. Kungathuthukisa ngempumelelo amandla eBonding oGundar udaka, kuthuthukiswe ukusebenza kokwakha, ukwandisa isikhathi esivulekile, ukuvikela ukuqhekeka futhi kuthuthukise ukumelana kwamanzi. Ngakho-ke, i-cellulose iziphotha isetshenziswa kabanzi ezintweni zokwakha ezifana nezindonga, phansi nezindonga ezingaphandle.
Imboni yezemithi
Ukusetshenziswa kwe-cellulose Tashers emkhakheni wezemithi kugxile kakhulu ekukhishweni kwezidakamizwa okudedelwa nokulawulwa okuqhubekayo kanye nokukhululwa kwamalungiselelo ezidakamizwa. Ngenxa yokuphambana kwayo okuhle kanye nokuzinikela kwamanzi okuguqukayo, izimpi ze-cellulose zivame ukusetshenziselwa ukulungiswa kwamathebulethi, amaphilisi kanye nokumiswa. Ngaphezu kwalokho, izithambiso ze-cellulose nazo zingasetshenziswa njengezitebele zezidakamizwa ukuze zithuthukise i-solubity kanye nezinga lokukhipha izidakamizwa.
Imboni yamakhemikhali yansuku zonke
Kumakhemikhali nsuku zonke, izithambiso ze-cellulose zisetshenziswa kabanzi njengabakhulu kanye nama-ejenti asolayo e-shampoo, i-conditioner, i-gel yokugeza, amazinyo, izimonyo neminye imikhiqizo. Kungathuthukisa umuzwa nokusebenza komkhiqizo, ukuthuthukisa ukuvumelana, ukuqina kanye nokunamathelisa umkhiqizo esikhunjeni. Ngasikhathi sinye, izithambiso ze-cellulose zine-biodegrade enhle kanye nobuthi obuphansi, ezihlangabezana nezidingo ezinobungane bemvelo zemikhiqizo yamakhemikhali yansuku zonke.
Imboni yokudla
Eminyakeni yamuva, ukusetshenziswa kwe-Celculle I-Celsulose Ether ingasetshenziswa njenge-persener, emulsifier, i-stabilizer kanye ne-ejenti ye-gelling yokudla, futhi isetshenziswa eziphuzweni, u-ayisikhilimu, jelly, amakhekhe nokunye ukudla. Ngaphezu kwalokho, i-cellulose ether inemisebenzi ethile yezempilo, efana nokwenza ngcono impilo yepheshana lesisu, njengesengezo se-fiber yokudla, futhi ithuthukise umsebenzi ojwayelekile wamathumbu.
Inkambu yokuvikela imvelo
Emkhakheni wokuvikelwa kwezemvelo, i-cellulose ether isetshenziswa njenge-ejenti yokwelashwa kwamanzi, ikakhulukazi ekwelashweni kwamanzi angcolile, ukwelashwa kwendle nokuhlanzwa kwamanzi emasimini kawoyela. Kungasiza ukunqanda izinto eziyingozi emanzini ngokulungisa ukubonwa nokuqina kwamanzi, futhi kudlala indima ebalulekile kwinqubo yokuhlanza kanye nokuphinda usebenzise kabusha. I-Celsulose Ether iyasetshenziswa futhi kumaphrojekthi wokuvikela imvelo efana nokuthuthukiswa kwenhlabathi kanye nokwelashwa kwe-leachate kokugcwaliswa komhlaba.
3. Ukucwaninga inqubekela phambili ye-cellulose ether
Ngokwanda okuqhubekayo kwesidingo semakethe se-cellulose ether, izikhungo zokucwaninga ngesayensi zasekhaya nakwamanye amazwe zenze ucwaningo oluningi ngenqubo yalo yokwenza, indlela yokuguqulwa kanye nesicelo esisha.
Ukuphuculwa kwenqubo ye-synthesis
Kunezindlela eziningi zokuhlanganiswa kwe-cellulose ether, kanye nezindlela zokuhlanganisa zendabuko ikakhulukazi zifaka indlela esomile yokuthezeka kanye nendlela yokuthezeka yemvula. Eminyakeni yamuva nje, ngokuthuthuka kwezidingo zokuvikelwa kwemvelo, izinqubo zokuhlanganiswa okuluhlaza zithole ukunakwa kakhulu. Ubuchwepheshe obusha obunjengobuhle bokuthembela kwe-fluid kanye ne-microwave-microwave bunciphisa izindleko zokukhiqiza ngempumelelo, bathuthukise ukusebenza kahle kokukhiqiza, futhi banciphise ukungcoliswa kwemvelo.
Ukuguqulwa kokusebenza
Ukuguqulwa kokusebenza kwe-cellulose ether nakho kuyisihloko esishisayo ocwaningweni lwamanje. Ngokuguqulwa, ukuzinza okushisayo, ukuSolubity, i-acid kanye nokuphikiswa kwe-alkali nezinye izakhiwo ze-cellulose ether zingathuthukiswa ukuze kuhlangabezane nezidingo zezinkambu ezahlukahlukene. Isibonelo, embonini yezokwakha, ukuze uthuthukise ukunamathela nokugcinwa kwamanzi kwe-cellulose ether, abacwaningi bethula amaqembu ahlukene okusebenza ukuze athuthukise ukusebenza kwawo.
Ukuhlola okusha kwesicelo
Ngokuthuthuka kwesayensi nobuchwepheshe, ukusetshenziswa kwe-cellulose ether emikhakheni evelayo kuyaqhubeka ukwandisa, njengokusetshenziswa kwama-elekthronikhi, amadivaysi e-opoleectronic, njll. Isibonelo, kusetshenziswe amaphrojekthi wokucwaninga ngesayensi. Ngokuzayo, ngokuthuthuka okusheshayo kwezinto ezihlakaniphile kanye namandla aluhlaza, i-cellulose ether izodlala indima ebaluleke kakhulu kule mikhakha.
4. I-future Development Trend
Njengesimo semvelo esinobungane nemvelo esivuselelekayo, i-cellulose ether inamathemba abanzi wesicelo. Njengoba isidingo sabantu sokuvikelwa kwemvelo kanye nentuthuko esimeme siyaqhubeka ukwanda, ucwaningo nokusetshenziswa kwezithambisi ze-cellulose kuzothambekela kwizinkomba ezilandelayo:
Ukuvikelwa okuluhlaza kanye nezemvelo: Abaphenyi bazoqhubeka nokuhlola izinqubo zokukhiqiza eziluhlaza okwesibhakabhaka nezinto ezivuthiwe ukunciphisa ukungcoliswa kwemvelo ngesikhathi sokukhiqiza.
Ukusebenza okuphezulu: Ngokushintshana okuthe xaxa kanye nokwenza izinto ezintsha, ukusebenza kwesicelo se-Cellulose Tashestments ezindaweni eziphakeme, njengokushisa okuphezulu, okushisa okuphansi noma izindawo ezinamandla ze-alkali kanye ne-alkali kanye ne-alkali kanye ne-alkali kanye ne-alkali kanye ne-alkali.
I-Multifunctional: yakha izimpi ze-cellulose ezinemisebenzi eyinhlanganisela ukukhulisa izindawo zabo zohlelo lokusebenza. Isibonelo, ukuthuthukiswa kwe-cellulose izithatheketha ngokuziphalisayo nezici zokuphendula ezihlakaniphile kuzohlinzeka ngezinketho ezintsha zezinto ezihlakaniphile nokukhiqiza okuhle.
Njengekhemikhali elibalulekile le-polymer lamakhemikhali, izithambiso ze-cellulose zinezinhlobonhlobo zamandla wesicelo. Ngokujula kocwaningo, ubuchwepheshe be-synthesis, izindlela zokuguqulwa kanye nezinkundla zohlelo lokusebenza lwe-cellulose afes kukhula njalo. Esikhathini esizayo, abapholishi beCellulose bazonaka kakhulu umkhuba wokuthuthuka kokuvikelwa kwemvelo okuluhlaza, ukusebenza okuphezulu kanye nokusebenza okusebenzayo, futhi kudlala indima ebalulekile ezimbonini ezahlukahlukene.
