Yini i-viscosity ephansi ye-celmulaose ether?

I-viscosity ephansi iselula I-Cellulose Afers isetshenziswa kabanzi ezinkundleni ezahlukahlukene zezimboni. Zisetshenziswa njengabakhulu, abaqinisi, izithasiselo, amafomu efilimu, njll. Kulezi zimo eziningi zohlelo. Uma kuqhathaniswa nesilinganiso esiphakeme se-cellule surtule

1. Imiqondo eyisisekelo

I-Cellulose iyi-polymer ejwayelekile kunazo zonke emhlabeni, eyakhiwa amayunithi we-glucose ezindongeni zeseli zezitshalo. Yize i-cellulose yemvelo ingenakufakwa emanzini futhi iswele i-thermoplasticity, izithambiso ze-cellulose zingakhiqizwa ngokuguqulwa kwamakhemikhali. Lezi zisulu eziguquliwe ze-cellulose derivatives zibonisa i-soubity ehlukile nezakhiwo ezisebenzayo kuma-solvents ahlukahlukene.

I-Cellulose Afers ifaka izinhlobo eziningi, njenge-methyl cellulose (MC), i-Hydroxyswethyl cellulose (HPMC), njll. (ama-MPA) kanye nemizuzwana engamakhulu ambalwa imigodi.

2. Inqubo yokukhiqiza

Ukukhethwa Kwezinto Ezisetshenziswayo Ze-Cellulose
Ukwelashwa kwe-Alkalinization: I-Cellulose iphathwa nge-alkali (efana ne-sodium hydroxide) ukuyenza iphinde isebenze lapho iguqulwa ngamakhemikhali.
Ukusabela kwe-Etherification: Ukwethulwa kwama-ejenti aphelelisayo (njenge-methyl chloride, i-ethylene oxide, i-plyylene glycol) ivumela amaqembu e-hydroxy kuma-ejeli athembisayo ukuze athole i-ejenti le-etheriose.
Ukungathathi hlangothi nokugeza: Umkhiqizo wokuphendula awuthathi hlangothi futhi ugezwe ukuze ususe amakhemikhali angenakuliwe kanye nemikhiqizo.
Ukomisa nokuchoboza: I-ether ekhiqizwayo ye-cellulose yomisiwe futhi ichotshozwa usayizi oyifisayo.
Ngokulawula izinga lokuthezeka kanye nemibandela yokuphendula, izici ze-viscosity ze-cellulose afer zingashintshwa ukuze kutholakale imikhiqizo ephansi ye-viscosity.

3. Izici

I-Viscosity ephansi: Isixazululo sinokubona okuphansi, okulula ukusiphawula nokufafaza, futhi kufanelekile izinhlelo zokusebenza ezidinga ukumelana okuphansi.
I-solubity enhle: ingancibilika ngokushesha emanzini noma izixazululo ze-organic ukwakha isixazululo noma ukuhlakazwa okufanayo.
Impahla enhle ekwakheka ifilimu: ingakha ifilimu ebushelelezi, efanayo, elungele izinhlelo zokusebenza zokuhlanganisa kanye nezinhlanganisela.
I-Chemical Invertness: inokuqina okuhle kwamakhemikhali futhi akulula ukuphendula nezinye izithako.
I-BioCOMTILibility: Ngokuvamile akuwona ubuthi, okungacasuli, futhi kuphephile ezintweni eziphilayo.

4. Izindawo zohlelo lokusebenza

Izinto zokwakha
Ezintweni zokwakha, i-cellulose tallule-cellulosity ephansi esetshenziswa njengabakhulu kanye nama-ejenti agcina amanzi ngenxa yodaka, ama-plasters kanye nokunamathela. Bangakwazi ukuthuthukisa ukusebenza kokwakha, banciphise ukuqhekeka okuhlambalazayo, futhi bandise amandla amabhondi nokuqina.

Ukumboza kanye nama-inks
I-SuppleLosity-Vislulose Tallule Basiza ukulungisa izakhiwo ze-rheological, bathuthukise izakhiwo zokwakha, futhi bavimbele ukufundwa kwe-pigment.

Amakhemikhali nezimonyo
Emikhakheni kanye nezimonyo, i-cellulose ephansi ye-cellulose asetshenziselwa ukulungiselela ukugembula kwamathebhulethi, okhilimu, nama-gels, njll. Banganikeza izakhiwo ezinhle kakhulu zefilimu, ukuqina, kanye nokuqina.

Imboni yokudla
Embonini yokudla, i-viscelise ephansi ye-cellulose izithathi esetshenziswa njengezengezo zokudla zokuqina, ukuzinza kokuthuthuka kanye nokwenza ngcono ukuthungwa, njengemikhiqizo yobisi, amasoso kanye nemikhiqizo ebhakiwe.

Amafutha negesi
Embonini kawoyela negesi, i-visceliosity ephansi ye-cellule tallule asetshenziswa njengabakhuthele kanye nokuzigcina ngamanzi okumba, kusiza ukulawula i-RHEOLOON kanye nokumiswa.

I-5. Izinzuzo nokubi

I-Viscosity ephansi: Kulula ukusingatha kanye nokusebenza, ilungele izinhlelo zezinga lokugeleza eliphakeme.
I-solubity enhle: Ukuchithwa okusheshayo, okulula ukulungiselela izixazululo.
I-Vortility: Ilungele ukusetshenziswa okuhlukahlukene futhi inezinhlobonhlobo zamathemba wesicelo.
Ukuvikelwa Kwezemvelo: Iningi le-cellulose iTefers i-biodegradable futhi inobungane bemvelo.
Okubi:

Izindleko eziphakeme: Ngenxa yenqubo eyinkimbinkimbi yokukhiqiza, izindleko ze-visceluase ephansi ye-cellule tallule
Ukuqina okulinganiselwe: ngaphansi kwezimo ezithile ezimbi kakhulu, njengokushisa okuphezulu noma okuphezulu kwe-pH, ukuqina kungathinteka.

6. Izitayela Zokuthuthuka Okuzayo

Ukwenza ngcono izinqubo zokukhiqiza: Ukunciphisa izindleko zokukhiqiza kanye nokwenza ngcono ikhwalithi yomkhiqizo ngokwenza ngcono imibandela yokuphendula nokugeleza kwenqubo.
Ukuguqulwa okusebenzayo: Ukuthuthukisa izithambisi ze-cellulose ezinemisebenzi ethile (njengokunamathela okuthuthukile kanye nezinto ezikhethekile ezenziwe ngefilimu) ukufeza izidingo zohlelo lokusebenza ezihlukile.
Ukuvikelwa Kwezemvelo Nokusimama: Ukukhuthaza ukusetshenziswa kwezinsizakusebenza ezivuselelekayo kanye nezinqubo ezinobungani bemvelo ukunciphisa umthelela emvelweni.

Njenge-cellulose etholakalayo, i-cellulose ephansi ye-cellule Abadlali nje kuphela iqhaza elibalulekile ezinkambeni zendabuko, kodwa futhi bakhombisa amandla amakhulu ezicelo ezifufusa. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nezinguquko ekufuneni kwemakethe, amathemba wesicelo se-sulvosiosiose ephansi ye-celtule
