Mu bigize ifu yumye,eteri ya seluloseni ikintu cy'ingenzi gifite ingano nto y'inyongera, ariko gishobora kunoza cyane imikorere yo kuvanga no kubaka kwa morti. Mu magambo make, hafi ya byose bishobora kugaragara mu kuvanga amazi bya morti bishobora kubonwa n'amaso yambaye ubusa bitangwa na cellulose ether. Ni cellulose derivative iboneka hakoreshejwe cellulose iva mu mbaho n'ipamba, igakorana na caustic soda, hanyuma igakoreshwa etherifying hakoreshejwe etherifying.
Ubwoko bwa ether za selulosi
A. Hydroxypropyl methyl cellulose (HPMC), ikorwa ahanini mu ipamba itunganyijwe neza cyane nk'ibikoresho fatizo, irashyuha cyane mu gihe cy'ubushyuhe.
B. Hydroxyethyl methylcellulose (HEMC), eteri ya cellulose itari ionic, ni ifu yera mu buryo busa, nta mpumuro kandi nta buryohe.
C. Hydroxyethyl cellulose (HEC), surfactant idafite ionic, isa n'umweru, nta mpumuro, nta buryohe kandi ifu yoroshye gutemba.
Izivuzwe haruguru ni eteri za cellulose zitari ionic, na eteri za cellulose za ionic (nk'izengurutse karuboksimetili CMC).
Mu gihe cyo gukoresha ifu yumye, kubera ko cellulose ionic (CMC) idahindagurika iyo hari iyoni za kalisiyumu, ntabwo ikoreshwa cyane mu buryo bwa gelling inorganic hamwe na sima na lime nk'ibikoresho byo gusimbuza. Hari ahantu hamwe mu Bushinwa, hari putties zimwe na zimwe zo mu nkuta zitunganywa na sitashi yahinduwe nk'ibikoresho by'ingenzi byo gusimbuza na ifu ya Shuangfei nk'umunyururu zikoresha CMC nk'umubyibuho. Ariko, kubera ko iki gicuruzwa gikunze kwibasirwa n'ibihumyo kandi ntikirwanya amazi, kirakurwa buhoro buhoro ku isoko. Kuri ubu, ether ya cellulose ikoreshwa cyane mu Bushinwa ni HPMC.
Cellulose ether ikoreshwa cyane cyane nk'ikintu gikomeza amazi no kugabanya ubukana mu bikoresho bishingiye kuri sima.
Imikorere yayo yo kubika amazi ishobora kubuza substrate kwinjiza amazi menshi no kubangamira imyuka y'amazi, kugira ngo sima igire amazi ahagije iyo ivanywemo amazi. Fata urugero rw'igikorwa cyo gusimbuza. Iyo sima isanzwe ikoreshejwe ku buso bw'ibanze, substrate yumye kandi ifite imyenge ihita ifata amazi menshi ava muri iyo sima, kandi urwego rwa sima ruri hafi y'urwego rw'ibanze rutakaza byoroshye amazi akenewe kugira ngo amazi anyure. , bityo ntabwo ishobora gukora sima ifite imbaraga zo gufatanya ku buso bw'ubutaka, ahubwo ikunda no kugorama no gushonga kw'amazi, ku buryo urwego rwa sima yo hejuru rworoshye kugwa. Iyo grout ikoreshejwe ari nto, biroroshye kandi gukora imyenge muri grout yose. Kubwibyo, mu gihe cyashize cyo gusimbuza hejuru, amazi akunze gukoreshwa mu kubanza kunyobwa muri substrate, ariko iki gikorwa ntigitwara akazi kenshi kandi gitwara igihe kinini gusa, ahubwo no kugenzura ubwiza bw'igikorwa biragoye.
Muri rusange, uburyo amazi abikwa mu cyuma cya sima yiyongera uko ingano ya eteri ya selulosi yiyongera. Uko eteri ya selulosi yongewemo irushaho kuba nini, ni ko amazi abikwa neza.
Uretse kubika amazi no kuyagwingira, eteri ya selulose igira ingaruka ku zindi nshingano za sima, nko kugabanya, gukurura umwuka, no kongera imbaraga z'imibanire. Eteri ya selulose igabanya umuvuduko w'imikorere no gukomera kwa sima, bityo ikamara igihe kinini. Kubwibyo, rimwe na rimwe ikoreshwa nk'umuti ugabanya ubukana bw'amazi.
Hamwe n'iterambere ry'uruvange rw'ibintu byumye,eteri ya seluloseYabaye imvange y'ingenzi ya sima. Ariko, hari amoko menshi n'ibipimo bya eteri ya selulose, kandi ubwiza hagati y'amatsinda buracyahindagurika.
