Ni iyihe soko karemano ya hydroxyethyl cellulose?

Hydroxyethyl cellulose (HEC) ni polymer idashonga mu mazi ikoreshwa cyane mu kwisiga, mu miti, mu marangi, mu gusiga irangi, mu bwubatsi no mu bindi. Ifite ubunini bwiza, irangi riturika, irangi rikwirakwira, irangi rituma amazi ahinduka, ikora filime, ifata amazi neza n'ibindi, bityo ikaba ingirakamaro mu nganda nyinshi. Ariko, hydroxyethyl cellulose ntiboneka mu bikoresho karemano, ahubwo iboneka binyuze mu guhindura cellulose karemano hakoreshejwe imiti. Kugira ngo tugere kuri iyi ntego, kugira ngo dusobanukirwe isoko karemano ya hydroxyethyl cellulose, tugomba kubanza gusobanukirwa inkomoko n'imiterere ya cellulose.

Isoko karemano ya selulose
Selulosi ni imwe muri polimeri organic nyinshi cyane ku isi kandi iboneka cyane mu nkuta z'uturemangingo tw'ibimera, cyane cyane mu bimera by'ibiti, ipamba, ifilakisi n'izindi fibre z'ibimera. Ni igice cy'ingenzi mu miterere y'ibimera kandi gitanga imbaraga n'ubudahangarwa bya mekanike. Igice cy'ibanze cya selulosi ni molekile ya glucose, ihuzwa n'imigozi ya β-1,4-glycosidic kugira ngo ikore imiterere y'uruhererekane rurerure. Nk'ibikoresho bya polimeri karemano, selulosi ifite imiterere myiza ya fiziki na shimi, bigatuma iba ibikoresho by'ingenzi ku bintu bitandukanye bikomokaho.

Uburyo bwo gutegura hydroxyethyl cellulose
Nubwo selulosi ubwayo ifite imiterere myiza myinshi, urwego rwayo rwo kuyikoresha ni ruto. Impamvu nyamukuru ni uko selulosi ifite ubushobozi buke bwo gushonga, cyane cyane ubushobozi buke bwo gushonga mu mazi. Kugira ngo banoze iyi miterere, abahanga mu bya siyansi bahindura selulosi mu buryo bwa shimi kugira ngo bategure ibintu bitandukanye biva muri selulosi. Selulosi ya Hydroxyethyl ni eteri ya selulosi ishongera mu mazi iboneka binyuze mu gukurura selulosi karemano binyuze mu gukora imiti.

Mu buryo bwihariye bwo gutegura, cellulose karemano ibanza gushonga mu gisubizo cya alkali, hanyuma ethylene oxide ikongerwa muri sisitemu y'inyito. Inyito ya ethoxylation y'amatsinda ya ethylene oxide na hydroxyl muri cellulose ibaho kugira ngo ikore hydroxyethyl cellulose. Iri hinduka ryongera ubushobozi bwo gushonga kw'iminyururu ya cellulose, bityo bikanoza ubushobozi bwayo bwo gushonga no gushonga kwayo mu mazi.

Inkomoko y'ibikoresho by'ibanze
Ibikoresho karemano by'ingenzi byo gutegura selulosi ya hydroxyethyl ni selulosi, kandi amasoko karemano ya selulosi arimo:

Ibiti: Selulosi iri mu biti ni nyinshi, cyane cyane mu biti by’ibiti binini n’ibibabi binini, aho selulosi ishobora kugera kuri 40%-50%. Ibiti ni bimwe mu bikomoka cyane kuri selulosi mu nganda, cyane cyane mu gukora impapuro no gukora ibikomoka kuri selulosi.

Ipamba: Fibre y'ipamba igizwe hafi na cellulose yuzuye, kandi ingano ya cellulose iri mu ipamba irenga 90%. Bitewe n'uko isuku yayo ikabije, fibre y'ipamba ikunze gukoreshwa mu gutegura ibintu byiza biva muri cellulose.

Insinga z'ibimera nka flax na hemp: Izi nsinga z'ibimera nazo zikungahaye kuri cellulose, kandi kubera ko izi nsinga z'ibimera akenshi ziba zifite imbaraga nyinshi mu ikoranabuhanga, zifite n'akamaro mu gukuramo cellulose.

Imyanda ikomoka ku buhinzi: harimo ibyatsi, ibyatsi by'ingano, ibyatsi by'ibigori, nibindi. Ibi bikoresho birimo ingano runaka ya selulose, kandi selulose ishobora gukurwamo binyuze mu nzira zikwiye zo gutunganya, igatanga isoko ihendutse kandi ishobora kongera gukoreshwa y'ibikoresho fatizo byo gukora ibikomoka kuri selulose.

Ahantu hakoreshwa hydroxyethyl cellulose
Bitewe n'imiterere yihariye ya hydroxyethyl cellulose, ikoreshwa cyane mu nzego nyinshi. Ibi bikurikira ni bimwe mu bintu by'ingenzi bikoreshwa:

Inganda z'ubwubatsi: Hydroxyethyl cellulose ikoreshwa cyane mu bikoresho by'ubwubatsi nk'ikintu gikomeza ubukonje no kubika amazi, cyane cyane mu gishishwa cya sima, gypsum, ifu ya putty n'ibindi bikoresho, bishobora kunoza neza imiterere y'ubwubatsi n'uburyo bwo kubika amazi by'ibikoresho.

Inganda zikora imiti ikoreshwa buri munsi: Mu isabune, ibikoresho byo kwita ku ruhu, shampoo n'ibindi bikoresho bikoreshwa buri munsi, hydroxyethyl cellulose ikoreshwa nk'ingufu zo gukurura no gushimangira kugira ngo yongere ibyiyumvo n'ubudahangarwa bw'umuti.

Amarangi n'amabara: Mu nganda zikora amabara, hydroxyethyl cellulose ikoreshwa nk'ikintu gikomeza ubushyuhe no kugenzura rheology kugira ngo yongere ubushobozi bwo gukora neza kw'amabara no kwirinda kugwa.

Ubuhanga mu by'imiti: Mu gutegura imiti, hydroxyethyl cellulose ishobora gukoreshwa nk'ikintu gifata, gikonjesha kandi gihagarika imiti kugira ngo yongere imiterere yo kuyisohora no kuyigumana neza.

Nubwo hydroxyethyl cellulose atari ikintu gisanzwe, ibikoresho byayo by'ibanze, cellulose, biboneka cyane mu bimera mu bidukikije. Binyuze mu guhindura imiti, cellulose karemano ishobora guhindurwamo hydroxyethyl cellulose ifite imikorere myiza kandi ikoreshwa mu nganda zitandukanye. Ibimera karemano nk'ibiti, ipamba, flax, nibindi bitanga isoko ryinshi ry'ibikoresho fatizo byo gukora hydroxyethyl cellulose. Bitewe n'iterambere rya siyansi n'ikoranabuhanga no kwiyongera kw'ibikenewe mu nganda, inzira yo gukora hydroxyethyl cellulose nayo ikomeje kunozwa, kandi byitezwe ko izagaragaza agaciro kayo kadasanzwe mu bindi bikorwa mu gihe kizaza.
