Izakhiwo Ezivamile Zomzimba Nezamakhemikhali kanye Nokusetshenziswa Kwe-Cellulose Ethers
I-cellulose ethers iyiqembu lama-polymers ancibilika emanzini atholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Lezi zinto eziphuma ku-cellulose zisetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zazo ezihlukile kanye nokuhlukahluka. Nazi ezinye izici ezivamile zomzimba namakhemikhali zama-cellulose ethers kanye nokusetshenziswa kwawo okuvamile:
- Izakhiwo Zomzimba:
- Ukubukeka: Ama-cellulose ether ngokuvamile avela njengezimpushana ezimhlophe ukuya kokumhlophe noma ama-granules.
- Ukunyibilika: Ziyakwazi ukuncibilika emanzini nakwezinye izincibilikisi eziphilayo, zakha izixazululo ezicacile, ezine-viscous.
- I-Hydration: I-Cellulose ethers inamandla okumunca futhi agcine amanzi amaningi, okuholela ekuvuvukeni nasekwakhekeni kwejeli.
- I-Viscosity: Abonisa izakhiwo ezijiyayo, ezinamaleveli e-viscosity ahluka kuye ngohlobo nesisindo samangqamuzana e-cellulose ether.
- Ukwakhiwa Kwefilimu: Amanye ama-cellulose ether anezinto zokwakha ifilimu, eziwavumela ukuthi akhe amafilimu aguquguqukayo nahlangene lapho omisiwe.
- Ukuzinza Kokushisa: Ama-cellulose ether ngokuvamile abonisa ukuzinza okuhle kokushisa, nakuba izakhiwo ezithile zingahluka kuye ngohlobo nezimo zokucubungula.
- Izakhiwo Zekhemikhali:
- Amaqembu Asebenzayo: Ama-cellulose ethers aqukethe amaqembu e-hydroxyl (-OH) kumgogodla we-cellulose, ngokuvamile ashintshwa ngamaqembu e-ether afana ne-methyl, i-ethyl, i-hydroxyethyl, i-hydroxypropyl, noma i-carboxymethyl.
- I-Degree of Substitution (DS): Le pharamitha ibhekisela enanini eliyisilinganiso lamaqembu e-ether ngeyunithi ngayinye ye-anhydroglucose kuketango le-cellulose polymer. Ithinta ukunyibilika, i-viscosity, nezinye izici ze-cellulose ethers.
- Ukuzinza Kwamakhemikhali: Ama-cellulose ethers ngokuvamile azinzile ngaphansi kwezinhlobonhlobo zezimo ze-pH futhi abonisa ukumelana nokuwohloka kwamagciwane.
- I-Crosslinking: Amanye ama-ether e-cellulose angaxhunywa ngamakhemikhali ukuze athuthukise izakhiwo zawo zemishini, ukumelana namanzi, nezinye izici.
- Ukusetshenziswa Okuvamile:
- Imboni Yokwakha: Ama-Cellulose ether asetshenziswa kakhulu njengama-thieners, ama-ejenti okugcina amanzi, kanye nezilungisi ze-rheology ezintweni zokwakha ezifana nodaka, ama-grouts, izinto zokunamathisela, kanye nemikhiqizo eyenziwe nge-gypsum.
- Ezemithi: Ziqashwa njengezibophezelo, ama-disintegrants, abakhiqizi bamafilimu, nezishintshi ze-viscosity ekwakhiweni kwemithi, okuhlanganisa amaphilisi, amaphilisi, ama-suspension, kanye nama-topical creams.
- Imboni Yokudla: Ama-cellulose ether asebenza njengamajiya, ama-stabilizer, ama-emulsifiers, kanye nezishintshisi zokuthungwa emikhiqizweni yokudla ehlukahlukene, okuhlanganisa amasoso, okokugqoka, imikhiqizo yobisi, nezinto ezibhakwayo.
- Imikhiqizo Yokunakekela Umuntu: Isetshenziselwa izimonyo, izinto zokugeza, kanye nemikhiqizo yokunakekela umuntu siqu njengama-shampoos, ama-conditioner, ama-lotion, nama-creams ukuze ajiye, aqinise, futhi enze ifilimu.
- Amapende nama-Coatings: Ama-cellulose ethers asebenza njengama-thickeners, ama-rheology modifiers, nama-stabilizer kumapende asekelwe emanzini, ama-coatings, nama-adhesives, athuthukisa izakhiwo zawo zokusebenza nokusebenza.
ama-cellulose ether athola ukusetshenziswa okusabalele kuzo zonke izimboni ngenxa yohlu lwawo oluhlukahlukene lwezakhiwo nokusebenza kwawo. Ikhono labo lokushintsha i-viscosity, ukuthuthukisa ukuthungwa, ukusimamisa ukwakheka, nokuhlinzeka ngamakhono okwenza ifilimu kubenza izithasiselo ezibalulekile emikhiqizweni nasezinqubweni eziningi.
