Focus on Cellulose ethers

Kungani umthamo wodaka ukhula ngemva kokwengeza i-cellulose ether?

1. Isingeniso se-cellulose ether:

Isakhiwo Sekhemikhali: Ama-cellulose ether angama-polymers ancibilika emanzini atholakala ku-cellulose, i-polysaccharide yemvelo etholakala ezindongeni zamaseli ezitshalo. Iqukethe amayunithi eglucose aphindaphindayo axhunywe ngamabhondi e-β-1,4-glycosidic.

I-Hydrophilicity: I-Cellulose ether i-hydrophilic, okusho ukuthi inokuhlangana okunamandla kwamanzi.

2. Indima ye-cellulose ether odakeni:

Ukugcinwa kwamanzi: Omunye wemisebenzi eyinhloko ye-cellulose ether odakeni ukuthuthukisa ukugcinwa kwamanzi. Yakha ifilimu elincanyana elizungeze izinhlayiya zikasimende, linciphisa ukuhwamuka kwamanzi futhi liqinisekise inqubo ende yokukhipha amanzi.

Thuthukisa ukusebenza kahle: I-Cellulose ether isebenza njengesishintshi se-rheology ukuze kuthuthukiswe ukusebenza kodaka. Lokhu kubaluleke kakhulu ekusetshenzisweni okufana nokuplasta nokunikezela.

3. Umthelela kuvolumu yodaka:

Ukumuncwa Amanzi: Imvelo eyi-hydrophilic yama-cellulose ether ibenza bakwazi ukumunca amanzi engxubeni. Njengoba ikhula, inani eliphelele lamanzi odongeni liyakhula, okubangela ukwanda kwevolumu.

Ukungena komoya: Ukwengeza ama-cellulose ether kungase kwethule umoya odakeni. Amabhamuza omoya abanjiwe anomthelela ekwandiseni umthamo.

Ukwakheka kwembotshana: Ama-cellulose ether angathinta i-microstructure yodaka, enze inethiwekhi enezimbotshana. Lokhu kuguqulwa kwesakhiwo se-pore kubangela ukwanda okukhulu kwevolumu.

4.Inqubo yokukhipha amanzi kanye nokunwetshwa kwevolumu:

Ukukhipha amanzi okubambezelekile: Ama-cellulose ether anganciphisa inqubo yokugeleza kukasimende. Lokhu kubambezeleka kwe-hydration kuvumela ukusatshalaliswa okulinganayo kwamanzi ngaphakathi kodaka, okungase kuphumele ekwenyukeni kwevolumu.

Umthelela wokwelapha: Ukugcinwa kwamanzi okunwetshiwe okukhuthazwa ama-cellulose ethers kusiza ukunweba isikhathi sokuphulukisa, okuvumela izinhlayiya zikasimende ukuthi zikhiphe amanzi ngokuphelele futhi kuthinte umthamo wokugcina wodaka.

5. Ukusebenzisana nezinye izithako:

Ukusebenzisana kwe-binder: Ama-cellulose ether asebenzisana nezibophezelo zikasimende ukuze akhe i-matrix ezinzile. Lokhu kusebenzisana kuthinta ukuqondanisa kwezinhlayiya futhi kuholela ekwandiseni ivolumu.

I-Admixture synergy: Uma i-cellulose ethers isetshenziswa kanye nezinye izixube, umphumela we-synergistic ungase ube khona, uthinte isamba sevolumu yodaka.

6. Ukuhlakazwa nokusabalalisa izinhlayiya:

Ukuhlakazwa okufanayo: Uma i-cellulose ether ihlakazwa kahle odakeni, kungenza ukusabalalisa kwezinhlayiyana kufane kakhulu. Lokhu kufana kuthinta ukuminyana kokupakisha kanjalo nevolumu yodaka.

7. Izimo zemvelo:

Izinga Lokushisa Nokuswakama: Izimo zemvelo ezifana nezinga lokushisa nomswakama zingathinta ukuziphatha kwama-cellulose ethers odakeni. Izakhiwo zokuvuvukala nokumuncwa kwamanzi zingahluka ngaphansi kwezimo zemvelo ezihlukene, kuthinte umthamo.

8. Isiphetho:

Kafushane, ukukhuphuka kwevolumu okuphawulwe lapho kwengezwa ama-cellulose ethers emathangeni kuwumphumela wokusebenzelana okuyinkimbinkimbi okuhlanganisa ukumuncwa kwamanzi, ukubambezeleka kokufakwa kwamanzi, ukungena komoya, kanye nezinguquko ku-microstructure yodaka. Ukuqonda lezi zindlela kubalulekile ukuze kusetshenziswe ngokugcwele ama-cellulose ethers ezixubeni zodaka futhi kuzuzwe izakhiwo ezifiselekayo ezinhlelweni zokwakha.
