Cellulose ether waa nooc ka mid ah polymers-ka biyaha-milmi kara oo ka soo jeeda cellulose, taas oo ah qaybta ugu muhiimsan ee dhismaha derbiyada unugyada dhirta. Eter-ka Cellulose wuxuu leeyahay sifooyin badan oo gaar ah, oo ay ku jiraan haynta biyaha sare, dhumucnaanta, xidhitaanka, iyo kartida samaynta filimada. Guryahani waxay ka dhigaan ether-ka cellulose shay muhiim u ah warshado badan, dawooyin, iyo alaabada daryeelka shakhsi ahaaneed.

Mid ka mid ah sifooyinka muhiimka ah ee ether cellulose waa viscosity, taas oo loola jeedo caabbinta dareeraha socodka. Viscosity waa halbeeg muhiim ah oo saameeya waxqabadka iyo codsiga etherka cellulose ee alaabta kala duwan. Maqaalkan, waxaan ka wada hadli doonaa viscosity ether cellulose, oo ay ku jiraan cabbirkeeda, arrimaha saameeya, iyo codsigeeda warshadaha kala duwan.

Cabbirka Viscosity of Cellulose Ether

Viscosity ee etherka cellulose waxaa sida caadiga ah lagu cabbiraa iyadoo la isticmaalayo viscometer, kaas oo ah qalab cabbiraya heerka qulqulka dareeraha ee hoos yimaada saamaynta cufnaanta ama xoogga la dabaqay. Waxaa jira dhowr nooc oo viskometer ah, oo ay ku jiraan rotational, capillary, iyo viscometers oscillatory, mid kastaa wuxuu leeyahay faa'iidooyin iyo xaddidaad u gaar ah.

Viscometer-ka wareeggu waa aaladaha ugu badan ee la isticmaalo ee lagu cabbiro viscosity ether-ka cellulose. Qalabyadani waxay cabbiraan qulqulka loo baahan yahay si loogu rogo dunta ama rotor lagu dhex geliyo dareeraha si xawli joogto ah. Viscosity-ka ayaa markaa la xisaabiyaa iyadoo lagu salaynayo xiriirka ka dhexeeya qulqulka iyo xawaaraha wareegga.

Viscometers capillary, dhanka kale, waxay cabbiraan wakhtiga loo baahan yahay mug go'an oo dareere ah si uu ugu dhex socdo tuubada xididada cidhiidhiga ah ee hoos yimaada saamaynta cufisjiidka ama gradient cadaadis. Viscosity-ka ayaa markaa la xisaabiyaa iyadoo lagu salaynayo sharciga Poiseuille, kaas oo la xidhiidha heerka qulqulka qulqulka, dhexroorka tuubada, iyo culayska cadaadiska.

Viscometers oscillatory, kuwaas oo cabbiraya qallafsanaanta iyo soo kabashada dareeraha hoos yimaada cadaadiska sinusoidal xiirid, ayaa loo isticmaalaa in lagu cabbiro viscosity adag ee ether cellulose, taas oo ah viscosity-ku-tiirsanaanta soo noqnoqda.

Waxyaabaha Saameynaya Viscosity of Cellulose Ether

Viscosity ee etherka cellulose waxaa saameeya dhowr arrimood, oo ay ku jiraan miisaankeeda kelli, heerka beddelka, xoogga saarista, heerkulka, iyo heerka xiirid.

Miisaanka molecular: Viscosity of cellulose ether wuxuu kordhiyaa culeyska kelliga ah ee sii kordhaya, maadaama culeyska unugyadu sareeyo ay leeyihiin silsilado dhaadheer oo isku dheggan, taasoo horseedaysa caabbinta socodka.

Heerka beddelka: Heerka beddelka (DS) ee ether cellulose, taas oo tixraacaysa tirada kooxaha hydroxyl ee la beddelay unugga gulukooska ee silsiladda cellulose, waxay sidoo kale saamaysaa viscosity. Marka DS-ku uu kordho, viscosity ee ether-ka cellulose wuu kordhaa sababtoo ah isku-xidhka silsiladda oo kordhay iyo isdhexgalka molecular.

Isku-duubni: Mawduucyada ether-ka cellulose-ku waxa uu kordhiyaa xoogga saarista, maaddaama uruurinta sare ay keento silsilado isku-xidhka oo kordha iyo is-dhexgalka molecular.

Heerkulka: Maqnaanshaha ether-ka cellulose wuxuu hoos u dhacayaa heerkulka sii kordhaya, maadaama heerkulka sare uu keeno dhaqdhaqaaqa molecular korodhka iyo hoos u dhaca isdhexgalka intermolecular.

Heerka xiiridda: Maqnaanshaha ether-ka cellulose sidoo kale wuxuu ku xiran yahay heerka xiirta la dabaqay, maaddaama heerarka sare ee dhogorta ay keenayaan kororka isku-xidhka silsiladda iyo hoos u dhigista caabbinta socodka.

Codsiga Ether-ka Cellulose ee Warshadaha kala duwan

Ether-ka Cellulose waxaa si weyn loogu isticmaalaa warshado kala duwan sababtoo ah sifooyinka gaarka ah, oo ay ku jiraan viscosity. Qaar ka mid ah codsiyada muhiimka ah ee ether cellulose ee warshadaha kala duwan ayaa hoos looga wada hadlay.

Dhismaha: Eter-ka Cellulose waxa loo isticmaalaa dhumuc ahaan, wakiilka biyaha, iyo xidhaha alaabta dhismaha sida sibidhka, hoobiye, iyo gypsum. Waxay wanaajisaa karti-shaqaynta, joogtaynta, iyo ku-xidhka alaabtan, taasoo horseedaysa hagaajinta waxqabadka iyo adkeysiga.

Daawooyinka: Ether-ka Cellulose waxa loo istcimaalaa dawooyinka dawooyinka sida kiniiniyada, kaabsalka, iyo kiriimyada. Waxay wanaajisaa qulqulka, isku-buufinta, iyo viscosity ee hab-nololeedyada, taasoo horseedaysa hagaajinta gaarsiinta iyo xasilloonida daroogada.
