Cellulose ether

Ether ni itsinda ryibimera byahinduwe na selile, aho hydroxyl matsinda (-OH) ya molekile ya selile isimbuzwa amatsinda ya ether (-OR). Ihinduka ryongera imiterere ya selile, bigatuma irushaho kuba ingirakamaro mubikorwa bitandukanye.

Cellulose Ether yerekanye ko ari ingirakamaro cyane ya polymers ishingiye kuri kamere, isanga ikoreshwa mubice birimo ibiryo, ibicuruzwa byita ku muntu, imiti yo mu murima wa peteroli, ubwubatsi, impapuro, ibifunga, hamwe n’imyenda.;

Bafite agaciro kihariye mubikorwa bya farumasi bitewe nibiranga harimo ubushyuhe bwo hejuru bwikirahure, ubushyuhe bwo hejuru bwa chimique na fotokome, gukomera, kutagira kristu, ubushobozi bwa hydrogène, hamwe nuburozi buke.;

Ku bijyanye n'uburozi, ethers ya selile nta bushobozi ifite bwo gucengera binyuze muri gastrointestinal enterocytes kandi benshi basanzwe mubyemezo byemejwe n’ubuyobozi bw’ibiribwa n’ibiyobyabwenge muri Amerika.

Ether ya selulose ni polymer zishonga mumazi zakozwe no guhindura imiti ya selile.;

Ether nini yubucuruzi ya selulose irimo carboxymethylcellulose (CMC), methylcellulose (MC) nibikomoka kuri hydroxypropyl methylcellulose (HPMC) na hydroxyethyl methylcellulose (HEMC), hydroxyethylcellulose (HEC) nibikomoka kuri hydroxyethylcellulose (EHEC) ), hydroxypropyl selulose (HPC), na Ethylcellulose (EC).

Etherimikorere nka stabilisateur, kubyimbye, no guhindura ibishishwa mu nganda nyinshi, zirimo ibiryo, imiti, ibicuruzwa byita ku muntu, imiti yo mu murima wa peteroli, ubwubatsi, impapuro, ibifunga, n’imyenda.;

Mubisobanuro byatoranijwe, barushanwe hamwe na polimeri yubukorikori bwamazi (alcool polyvinyl, polyurethane Associative thickeners, polyacrylates) hamwe na polymers isanzwe ikemura amazi (xanthan gum, karrageenan, inzige zinzige).;

Guhitamo polymer bigenwa nigiciro / imikorere yubucuruzi, kuboneka, no koroshya ivugurura ryibicuruzwa bishingiye kubiciro / imikorere.

Ether ya selile ni ifu ya selulose ether yakozwe na fibre yinkwi cyangwa fibre ngufi itunganijwe nkibikoresho byingenzi, nyuma yo kuvurwa imiti hamwe nigisubizo cyibikoresho bya etherifingi nka chlorine etylene, chlorine propylene na okiside etilene.

Igikorwa cyo gukora selile ya ether iragoye.;

Ether ya selile itangirana no gukuramo selile mu ipamba cyangwa mu giti, hanyuma igahinduka selulose ya alkaline nyuma yo kongeramo hydroxide ya sodium hamwe na reaction ya chimique (igisubizo cya alkaline).;

Mubikorwa bya etherifyinga (reaction ya etherification), selile ya selile ikomoka kuri selile ya alkaline selile binyuze muburyo bwo gukaraba n'amazi, kumisha no gusya.

Ethers ya selile nibintu byingenzi byongerera imbaraga sima igezweho hamwe na gypsumu ishingiye kubikorwa byubaka.;

Cellulose ether itezimbere imiterere, itezimbere imashini, yongera ibicuruzwa, ubwishingizi kandi igabanya imyanda.

Cellulose ether itanga inyungu nyinshi icyarimwe; Biterwa nimirimo nko gufata amazi, gusiga amavuta, kongera imbaraga zo kurwanya-gukata, kurwanya kunyerera, kongera gukomera no kongera igihe cyo gufungura.;

Cellulose ether ikorana nigitekerezo cyambere, kugenzura neza, gucunga no gutanga serivisi nziza kubakiriya bo muri R&D.

Ether ya selile ni isuku nyinshi, ikabura amazi, polymers itari ionic yagenewe gukoreshwa nkibikoresho bifata amazi, kubyimba no gukora firime, imiti ikingira, guhagarika no kwigana imiti, binders na stabilisateur.

Ibikomoka kuri selile, umutungo kamere, mwinshi kandi ushobora kuvugururwa, ethers ya Cellulose imaze imyaka irenga 50 ikoreshwa mugutezimbere ibicuruzwa mubuvuzi bwihariye, imiti n'ibiribwa.
