Cellulose ether nicyiciro cyamazi ya elegitoronike ya polymers ikomoka kuri selile, nicyo kintu nyamukuru cyubaka urukuta rwibimera. Ether ya selile ifite ibintu byinshi byihariye, harimo kubika amazi menshi, kubyimba, guhambira, hamwe nubushobozi bwo gukora film. Iyi mitungo ituma selulose ether ari ingenzi mubicuruzwa byinshi byinganda, imiti, hamwe nubuvuzi bwihariye.

Imwe mu miterere yingenzi ya selile ether ni viscosity yayo, bivuga kurwanya amazi gutemba. Viscosity nikintu cyingenzi kigira ingaruka kumikorere no gukoresha selile ya selile mubicuruzwa bitandukanye. Muri iki kiganiro, tuzaganira ku bwiza bwa selile ya selile, harimo gupima, ibintu bigira ingaruka, no kuyikoresha mu nganda zitandukanye.

Gupima Viscosity ya Cellulose Ether

Ubukonje bwa ether ya selile isanzwe ipimwa hifashishijwe viscometero, nigikoresho gipima umuvuduko w umuvuduko wamazi bitewe ningufu zikomeye cyangwa imbaraga zikoreshwa. Hariho ubwoko bwinshi bwa viscometer, harimo kuzunguruka, capillary, na viscometer viscometer, buri kimwe gifite ibyiza byacyo.

Guhinduranya viscometer nibikoresho bikoreshwa cyane mugupima ubwiza bwa selile ether. Ibi bikoresho bipima urumuri rusabwa kugirango ruzunguruke ruzunguruka cyangwa rotor yibizwa mumazi kumuvuduko uhoraho. Ubukonje noneho bubarwa hashingiwe ku isano iri hagati ya torque n'umuvuduko wo kuzunguruka.

Ku rundi ruhande, viscometer ya capillary, bapima igihe gikenewe kugirango ingano ntarengwa y’amazi atembera mu muyoboro muto wa capillary utwarwa ningufu zikomeye cyangwa umuvuduko ukabije. Ubukonje noneho bubarwa hashingiwe ku itegeko rya Poiseuille, rihuza igipimo cy’imigezi n’ubukonje, diameter ya tube, hamwe n’umuvuduko ukabije.

Oscillatory viscometers, ipima ihinduka no gukira kwamazi munsi ya sinusoidal shear stress, ikoreshwa mugupima ububobere bukomeye bwa selile ether, aribwo bwenge bushingiye kumirongo.

Ibintu bigira ingaruka kuri Viscosity ya Cellulose Ether

Ubukonje bwa selile ya selile iterwa nibintu byinshi, harimo uburemere bwa molekile, urugero rwo gusimburwa, kwibanda, ubushyuhe, nigipimo cyogosha.

Uburemere bwa molekuline: Ubukonje bwa ether ya selile yiyongera hamwe no kongera uburemere bwa molekile, kubera ko polimeri iremereye cyane ifite iminyururu miremire ifatanye, bigatuma kwiyongera kwinshi gutemba.

Impamyabumenyi yo gusimbuza: Urwego rwo gusimbuza (DS) rwa selulose ether, bivuga umubare w’amatsinda ya hydroxyl yasimbuwe kuri glucose igice cyumunyururu wa selile, nacyo kigira ingaruka ku bwenge bwacyo. Mugihe DS yiyongera, ubwiza bwa selile ether bwiyongera kubera kwiyongera kwurunigi no guhuza imiyoboro.

Kwishyira hamwe: Ubukonje bwa selile ya selile yiyongera hamwe no kwiyongera kwinshi, kuko kwibanda cyane biganisha kumurongo no guhuza imikoranire.

Ubushyuhe: Ubukonje bwa selile ether igabanuka hamwe nubushyuhe bwiyongera, kuko ubushyuhe bwinshi butera kwiyongera kwa molekile no kugabanya imikoranire hagati yimitsi.

Igipimo cyogosha: Ubukonje bwa selile ya selile nayo iterwa nigipimo cyogosha cyogosha, kuko igipimo cyogosha cyinshi kiganisha kumurongo uhuza kandi bikagabanya kurwanya umuvuduko.

Gukoresha Cellulose Ether munganda zitandukanye

Cellulose ether ikoreshwa cyane mubikorwa bitandukanye kubera imiterere yihariye, harimo nubwiza bwayo. Bimwe mubikorwa byingenzi bya selile ether mu nganda zitandukanye byaganiriweho hepfo.

Ubwubatsi: Ether ya selile ikoreshwa nkibyimbye, kubika amazi, no guhuza ibicuruzwa byubaka nka sima, minisiteri, na gypsumu. Itezimbere imikorere, ihamye, hamwe no guhuza ibyo bicuruzwa, biganisha kumikorere myiza no kuramba.

Imiti yimiti: Cellulose ether ikoreshwa nkibintu byoroshye mumiti ya farumasi nka tableti, capsules, na cream. Itezimbere gutembera, kwikanyiza, hamwe nubwiza bwimikorere, biganisha kumiti itangwa neza kandi itajegajega.
