Ether ya selile ni ubwoko bwimikorere ya polymer ikorwa muburyo bwa chimique ihindura selile. Bafite imiterere yihariye yumubiri nubumashini kandi bikoreshwa cyane mubintu bitandukanye. Bitewe nibintu byiza bya selile ya ether, ikoreshwa ryayo ntirishobora gusa kunoza imikorere yibicuruzwa, ahubwo izana nuruhererekane rwiterambere nko gutuza, kubyimba, gufata amazi, no gusiga amavuta.
1. Ingaruka mbi
Imwe mumikorere yibanze ya selulose ethers irabyimbye, bigatuma igira agaciro gakomeye muri sisitemu yo gufata amazi. Ubukonje bwumuti ni ingenzi kumikorere yabwo, kandi ethers ya selile irashobora kongera cyane ububobere bwikibaho mugukora imiterere imwe ya molekile. Ether ya selile nka hydroxypropyl methylcellulose (HPMC) na hydroxyethyl selulose (HEC) igira ingaruka nziza zo kubyimba, kandi imiterere yabyo irashobora guhinduka hamwe nimpinduka zuburemere bwa molekile, urwego rwo gusimbuza nibindi bintu. Ibiti byijimye ntabwo byorohereza gutwikira gusa, ahubwo binongera imbaraga zo guhuza, bigatuma bikoreshwa cyane mubikoresho byubaka, impapuro zometseho impapuro, nibindi.
2. Gutanga amazi
Kubika amazi nundi murimo wingenzi wa selulose ethers. Ether ya selile irakwiriye cyane cyane kumazi ashingiye kumazi, ashobora kugumana neza neza kandi bikarinda koleo yumye vuba. Ibi nibyingenzi cyane kubidukikije aho ubuhehere bugenda bwuka vuba. Kurugero, mumashanyarazi ashingiye kuri sima cyangwa gypsumu yinganda zubaka, ether ya selile irashobora gukuramo amazi, kwaguka no gukora firime ya hydrata, ikongerera igihe cyakazi cyo gufatira hamwe no kurinda umutekano mugihe cyibikorwa byubwubatsi. Ibikoresho byo guhuza ntabwo byangizwa no gukama imburagihe. Iyi mikorere irakoreshwa no mubice nko gusiga amarangi ku rukuta hamwe no gufatira amatafari akeneye kugenzura amazi.
3. Kuzamura imikoranire hamwe no gufatira hamwe
Kwiyongera kwa selulose ether ntishobora kubyimba no kugumana amazi gusa, ariko kandi irashobora kunoza neza imbaraga zifatika zifatika. Amatsinda akora nka hydroxyl na ether ihuza imiterere ya molekile yayo irashobora gukora hydrogène ya hydrogène nindi mikoranire yumubiri nubumashini hamwe nubuso bwa aderend, bityo bikazamura ibifatika. Ibi bituma selile ya selile nziza cyane muguhuza impapuro, ibiti, ububumbyi nibindi bikoresho. Ubwinshi bwa selile ya selile itanga ibifatika neza hamwe nubwubatsi bworoshye, bikemerera gukora ibintu byiza bihuza kumurongo mugari wa substrate.
4. Kunoza ituze no kurwanya kunyerera
Mubikoresho byubaka cyangwa ibindi bifata cyane-viscosity, ether ya selile irashobora kandi kunoza uburyo bwo kunyerera bwa sisitemu. Ether ya selile irashobora gukora imiyoboro y'urusobekerane, ikagabanya umuvuduko wa binder, kugirango igipfundikizo gikomeze kigumane imiterere ihamye kandi ntikizanyerera bitewe nuburemere cyangwa ibintu byo hanze, cyane cyane ni ngombwa cyane mubidukikije nko kubaka amabati. . Byongeye kandi, selulose ether irashobora kandi guha imiti ifatika irwanya gutuza, irinde gusibanganya mugihe cyo kubika no kuyikoresha, kandi ikemeza uburinganire nigihe kirekire cyumuti.
5. Kunoza imikorere yubwubatsi
Cellulose ether ifite amavuta meza kandi akwirakwizwa, atezimbere cyane imikorere yayo mubifata. Ibifunga ukoresheje selile ya selile ntabwo byoroshye kuyikoresha gusa, ariko birashobora no gukora igipande cyoroshye kandi kimwe kidafatika kitongereye umubyimba, kugabanya umugozi mugihe cyo kubaka no kunoza uburambe bwabakoresha. Muri icyo gihe, ikoreshwa rya selile ya selile irashobora kandi kugabanya neza kugabanuka kwifata, kugabanya ibibazo byo guturika cyangwa gukuramo nyuma yo gutwikira, no kunoza ituze nigihe kirekire murwego rwo guhuza.
6. Kongera imbaraga zo kurwanya inzitizi
Mubintu bimwe bidasanzwe bikoreshwa mubidukikije, ibifatika bigomba kunyuramo inshuro nyinshi zikonje, nko kubaka hanze, ubwikorezi nizindi nzego. Ether ya selile ifite imbaraga zo gukonjesha-gukonjesha, zishobora kugumya guhagarara neza mugihe cy'ubushyuhe buke kandi bikarinda ibimera kwangirika mugihe cyizuba. Binyuze mu miterere ihamye ya selile, ether ya selile irashobora kugumana imiterere ihuza ibimera nubwo ihindagurika ryubushyuhe, bigatuma ryizerwa mugihe cyikirere gikabije. Ibi nibyingenzi byingenzi kuri sisitemu ifata bisaba igihe kirekire cyo hanze.
7. Gutanga ibidukikije
Nkibikomoka kuri selile karemano, selile ya selile ifite biodegradabilite nziza no kurengera ibidukikije. Bitandukanye na polymrike ya sintetike, ether ya selile ikomoka kubishobora kuvugururwa kandi ntibizatera umwanda mwinshi kubidukikije nyuma yo kubikoresha. Byongeye kandi, selile ya selile ifite imyuka mike y’imyuka ihindagurika (VOC) mugihe cyo kuyikoresha no kuyikoresha, kandi ikubahiriza ibisabwa n’amabwiriza agenga ibidukikije bigezweho. Kubwibyo, mugushushanya kwangiza ibidukikije byangiza ibidukikije, ethers ya selile yahindutse buhoro buhoro umubyimba mwiza. Bunga ibikoresho bibisi.
8. Urutonde runini rwa porogaramu
Bitewe nuburyo bwinshi, selile ya selile igira uruhare runini mubikorwa bifatika bifata inganda nyinshi. Mbere ya byose, mubijyanye nubwubatsi, ethers ya selulose ikoreshwa cyane mumasima ashingiye kuri sima hamwe na gypsumu yifashisha kugirango itange imikorere myiza yubwubatsi nimbaraga zihuza. Mubyongeyeho, ether ya selulose nayo ikoreshwa mugupakira no gufunga ibicuruzwa. Kubika amazi hamwe no kubyimba byongera neza ingaruka zo guhuza no kuramba kwimpapuro. Ether ya selile ikoreshwa kandi mubuvuzi, kole y'ibiryo ndetse no mubindi bice. Kubera imiterere yabyo idafite uburozi, impumuro nziza kandi ihamye, zujuje ibyangombwa bisabwa kubifata muri iyi mirima.
Nibikoresho byinshi bya polymer, selile ya ether ifite amahirwe menshi yo gukoreshwa mubifatika. Itezimbere cyane imikorere yifata kandi yujuje ibyifuzo byujuje ubuziranenge mu nganda zigezweho n’ubwubatsi binyuze mu ruhererekane rwimirimo nko kubyimba, gufata amazi, kunoza neza, kongera umutekano, no kunoza imikorere. Hamwe niterambere ryiterambere rya siyansi nikoranabuhanga hamwe n’abantu bagenda basabwa kurengera ibidukikije, uruhare rwa selile ya selile mu gufatira hamwe ruzarushaho kuba ingenzi, kandi ibyifuzo bizaza bizaguka.
