Zibukwa kanjani izimpi ze-cellulose futhi zinjani amakilasi?

I-Cellulose iyingxenye esemqoka yezindonga zamaseli ezitshalo, futhi iyona esatshalaliswa kabanzi ye-polysaccharide yemvelo, ibala imali engaphezu kuka-50% yokuqukethwe kwekhabhoni embusweni wezitshalo. Phakathi kwazo, okuqukethwe kweCellulose kokotini kusondele ku-100%, okuwumthombo we-cellulose omsulwa kakhulu. Ngokhuni olujwayelekile, ama-akhawunti we-cellulose ama-40-50%, futhi kukhona i-10-30% ehunyushellulose ne-20-30%. I-Cellulose Ether yithemu jikelele yezinhlobonhlobo zokutholwa ezitholwe ku-cellulose yemvelo njengento eluhlaza ngokusebenzisa ukusheshisa. Kungumkhiqizo owakhiwa ngemuva kwamaqembu e-hydroxy ku-cellulose macromolecule ngokwengxenye noma okufakwa ngokuphelele ngamaqembu ether. Kukhona i-intra-chain kanye nama-hydrogen bond ama-hydrogen kuma-cellulose macrozelo, okunzima ukuncibilikisa emanzini futhi cishe wonke ama-organic sol sol, kepha ngemuva kokuthezeka, kwandise kakhulu i-solubity emanzini kanye nezinto eziphilayo. Izakhiwo ze-solubity.

I-Cellulose Ether idume "le-monosodium yezimboni glutamate". Inezakhiwo ezinhle kakhulu njengokuqina kwesixazululo, i-solubiling enhle yamanzi, ukumiswa noma ukuqina kwe-latex, ukwakheka kwamafilimu, ukugcinwa kwamanzi, nokutholwa kwamanzi kanye nokunamathela. Futhi ayinabuthi futhi ayinambitha, futhi isetshenziswa kabanzi ezintweni zokwakha, umuthi, ukudla, izindwangu, amakhemikhali e-petroleum, izimayini, ama-papermaking, ama-polymerization, i-aerospace nezinye izinkambu eziningi. I-Cellulose Ether inezinzuzo zohlelo lokusebenza olubanzi, ukusetshenziswa okuncane kweyunithi, umphumela omuhle wokuguqulwa, kanye nobungane bezemvelo. Ingathuthuka kakhulu futhi ithuthukise ukusebenza komkhiqizo emkhakheni wokungezwa kwayo, okulungele ukwenza ngcono ukusebenza kahle kwezinsiza kanye nenani elingeziwe lomkhiqizo. Izithasiselo ezinobungani bemvelo ezibalulekile emikhakheni ehlukahlukene.

Ngokusho kwe-IoninIzation of Cellulose Ether, uhlobo lokufakazelwa kanye nomehluko ekuhlaseleni, i-cellulose ether ingahlukaniswa ngezigaba ezahlukahlukene. Ngokwezinhlobo ezahlukene zezithako, izithambiso ze-cellulose zingahlukaniswa zaba ngabaphambe kanye nabampofu abaxubekile. Ngokusho kwe-solubity, i-cellulose ether ingahlukaniswa imikhiqizo engenamanzi-infoluble imikhiqizo. Ngokusho kwe-ionization, ingahlukaniswa ibe yi-Ionic, i-nonic ehlanganisiwe nemikhiqizo exubile. Phakathi kwama-cellule-celluble tallulose, angezona izithambiso ezifana ne-HPMC zinokumelana kangcono nokulimala kwezingathwa kanye nokumelana nosawoti kune-ionic Cellulose Afers (CMC).

Ngabe ukhula kanjani embonini embonini?

I-Cellulose Ether yenziwa kusuka kukotini ecwengekile ngokusebenzisa i-alkalization, ukusheshisa nezinye izinyathelo. Inqubo yokukhiqiza yebanga le-HPMC kanye ne-FOD GRANGE HPMC ngokufanayo. Uma kuqhathaniswa nesakhiwo se-ether ye-celtulose yezakhiwo, inqubo yokukhiqiza ye-HPMC ne-HPMC ye-HPMC nebanga le-HPMC idinga ukulawula inqubo yokukhiqiza, futhi idinga ukuhlanzeka okuphezulu kwemishini kanye nemvelo yokukhiqiza.

Ngokwemininingwane enikezwe yi-China Cellulose Industry Association, inani eliphelele lokukhiqiza labakhiqizi abangewona ama-cellulose abakhiqizi abasemakhaya, njengeHercules Temple, njll. Kuneminye eyabakhiqizi abaningana abancane abangeyona eye-ether cellulose enekhono lokukhiqiza lamathani angaphansi kwama-4,000. Ngaphandle kwamabhizinisi ambalwa, iningi lazo likhiqiza ama-collulose ajwayelekile we-cellulose, enekhono eliphelele lokukhiqiza elingamathani angama-100,000 ngonyaka. Ngenxa yokuntuleka kwamandla ezezimali, amabhizinisi amancane amancane ahluleka ukufeza amazinga ekutshaleni imali ekuvikeleni kwamanzi kanye nokwelashwa kwegesi ukuze anciphise izindleko zokukhiqiza. Njengoba izwe kanye nomphakathi wonke kukhokha ngokwengeziwe ekuvikelweni kwemvelo, lawo mabhizinisi embonini engenakuhlangabezana nezidingo zokuvikelwa kwezemvelo zizovala kancane noma zinciphise ukukhiqizwa. Ngaleso sikhathi, ukugxila kwemboni ye-cellulose ether yezwe yami kuzokwenyuka.

Izinqubomgomo Zokuvikelwa Kwezemvelo Zemvelo ziya ngokuya ziqinile, futhi izidingo eziqinile zibekwa phambili kubuchwepheshe bokuvikela imvelo kanye nokutshala imali kwinqubo yokukhiqiza ye-cellulose ether. Izindlela zokuvikela ezemvelo ezisezingeni eliphakeme zandisa izindleko zokukhiqiza zamabhizinisi futhi kwakha umkhawulo ophezulu wokuvikelwa kwemvelo. Amabhizinisi angenakuhlangabezana nezidingo zokuvikelwa kwemvelo cishe kungenzeka avale kancane noma anciphise ukukhiqizwa ngenxa yokwehluleka ukufeza amazinga okuvikela ezemvelo. Ngokusho kweProspectus yenkampani, amabhizinisi anciphisa kancane kancane ukukhiqizwa kanye nokuyeka umkhiqizo ngenxa yezici zokuvikela imvelo ezibandakanya ukuthengiswa okuphelele kwamathani / ngonyaka ojwayelekile weBandla le-ether, elilungele ukwanda kwamabhizinisi ajwayelekile.

Kususelwa ku-cellulose ether, iyaqhubeka nokunwebeka ekupheleni okuphezulu nemikhiqizo engenye yenani eliphakeme
