Gusaba selile ether

Mubigize ifu yumye minisiteri,selile etherni ngombwa cyane hamwe numubare muto wongeyeho, ariko birashobora kunoza cyane imikorere yo kuvanga no kubaka minisiteri. Kubishyira mu buryo bworoshye, hafi ya yose yo kuvanga imiterere ya minisiteri ishobora kugaragara nijisho ryambaye ubusa bitangwa na selile. Nubugingo bwabonetse dukoresheje selile mubiti nipamba, bitwaje soda ya Caustic, hanyuma bikareba hamwe numukozi ushishikaje.

Ubwoko bwa selire

A. HydroxyPropyl Methyl Cellulose (HPMC), ikozwe ahanini ipamba ndende-yuzuye nkibikoresho fatizo, byangiritse byumwihariko mubihe bya alkaline.
B. HydroxyEthyyl Methylcellse (Hemc), ether itari ionic ether, ni ifu yera mumiterere, impumuroya kandi itaryoshye.
C. Hydroxyyeryl selile (hec), ikigo kitari gionactant, cyera mumiterere, impumuro idafite impumuro nziza, itaryoshye kandi yoroshye.

Ibyavuzwe haruguru ni erebire itari ionic ionic, na seliki ya selile (nka carboxymethyl cmc).

Mugihe cyo gukoresha ifu yumye minisiteri yumye, kubera ko selile ya selile idahungabana imbere ya Silcium, gake ikoreshwa muri sisitemu ya kalcium, ni gake ikoreshwa muri sisitemu ya kalciing na sime nkibikoresho bya sima. Ahantu hamwe mu Bushinwa, ibibanza byimbere byimbere byatunganijwe hamwe nibice byingenzi byahinduwe nibikoresho bya shuangfei nkuko byuzuza CMC nkabahuje. Ariko, kubera ko iki gicuruzwa gikunze kugaragara kandi ntabwo kirwanya amazi, buhoro buhoro kizavaho ku isoko. Kugeza ubu, ubugari bwa selile ikoreshwa cyane mubushinwa ni HPMC.

Uburenganzira bwa Cellulose bukoreshwa cyane nkumukozi ushinzwe kugumana amazi na Trickener mubikoresho bishingiye kuri sima

Imikorere yo kugumana amazi irashobora kubuza ishyaka ryinjira mumazi menshi kandi rikabangamira guhumeka, kugirango tumenye ko sima ifite amazi ahagije mugihe ari hydd. Fata igikorwa cya playsing nkurugero. Iyo ubucuruzi busanzwe bukoreshwa mubuso bwibanze, umutwe wumye kandi ugaragara uzakuramo amazi menshi, kandi sima yo gucikamo ibice byegeranye byoroshye kumazi. , ntabwo rero bidashobora gushinga gel ya sima gusa hamwe nimbaraga zo guhuza substrate, ariko nanone bikunze kurwana no kubona amazi, kugirango ubuso bwa siurme demes burry buroroshye kugwa. Iyo imbaraga zikoreshwa zinanutse, biroroshye kandi gushiraho ibice mubidugara byose. Kubwibyo, mugihe cyashize ibikorwa bya plastersing, amazi mubisanzwe akoreshwa kugirango abanze abanze, ariko iki gikorwa ntabwo ari ugutwara akazi gusa, ahubwo ni uburyo bwo gukora biragoye kubigenzura.

Muri rusange, kugumana amazi yo kwiyongera kwiyongera hamwe no kongera ibikubiye muri selile. Murundi ruswa rwongeyeho koherezwa kwa selile ether, icyubahiro cyiza.

Usibye kugumana amazi no kubyimba, uburenganzira bwa selile kandi bigira ingaruka kurindi mitungo ya sima, nko kudindiza, gushinga umwuka, no kongera imbaraga. Ubudodo bwa Cellulose bwije igenamiterere nuburyo bukomeye bwo gushimangira, bityo tugabana igihe cyakazi. Kubwibyo, rimwe na rimwe bikoreshwa nka coagulant.

Hamwe niterambere rya minisiteri yumye,selile etheryabaye sima ikomeye ya liver. Ariko, hariho ubwoko bwinshi nubumwe bwa selile, kandi ireme hagati yitsinda riracyahindagurika.
