Iselulosi ether

I-cellulose ethers liqela lemichiza ye-cellulose derivatives, apho amaqela e-hydroxyl (-OH) yee-molecule ze-cellulose athatyathelwa indawo ngamaqela e-ether (-OR). Olu hlengahlengiso luphucula iipropathi zeselulosi, luyenza ibe luncedo ngakumbi kumashishini ahlukeneyo.

I-Cellulose Ether ibonakalise ukuba luncedo kakhulu kwiipolymers ezisekelwe kwindalo, ukufumana isicelo kwiindawo ezibandakanya ukutya, iimveliso zokunakekelwa komntu, iikhemikhali zentsimi yeoli, ukwakhiwa, iphepha, i-adhesives, kunye neendwangu.

Zinexabiso elithile kwizicelo zamayeza ngenxa yeempawu ezibandakanya ubushushu obuphezulu beglasi, iikhemikhali eziphezulu kunye nokuzinza kweekhemikhali, ukunyibilika, icrystallinity elinganiselweyo, amandla okubopha i-hydrogen, kunye netyhefu ephantsi.;

Ngokubhekiselele kwityhefu, i-cellulose ethers ayinakho ukukwazi ukungena kwi-enterocyte yesisu kwaye ezininzi sele zifakwe kwimiqulu evunyiweyo yi-US Food and Drug Administration.

I-cellulose ethers ziipolymers ezinyibilikayo emanzini eziveliswa ngokuguqulwa kweekhemikhali zeselulosi.;

I-ethers ezinkulu ze-cellulose zorhwebo ziquka i-carboxymethylcellulose (CMC), i-methylcellulose (MC) kunye nezinto eziphuma ezifana ne-hydroxypropyl methylcellulose (HPMC) kunye ne-hydroxyethyl methylcellulose (HEMC), i-hydroxyethylcellulose (HEC) kunye ne-derivatives efana ne-ethyl hydroxyethylHEcellulose (i-methylethylHEcellulose) (MEHEC), i-hydroxypropyl cellulose (HPC), kunye ne-ethylcellulose (EC).

I-cellulose etherszisebenza njengezinzisi, i-thickeners, kunye neziguquli ze-viscosity kumashishini amaninzi, kubandakanywa ukutya, amayeza, iimveliso zokhathalelo lomntu, iikhemikhali zentsimi yeoli, ukwakhiwa, iphepha, izinto zokuncamathelisa kunye nempahla;

Kwizicelo ezikhethiweyo, zikhuphisana kunye kunye kunye neepolima zokwenziwa zamanzi ezinyibilikayo (i-polyvinyl alcohol, i-polyurethane associative thickeners, i-polyacrylates) kunye neepolima zendalo ezinyibilikayo emanzini (i-xanthan gum, i-carrageenan, itshungama yembotyi yeenkumbi).

Ukukhethwa kwepolymer kugqitywa ngexabiso / ukusebenza korhwebo, ukufumaneka, kunye nokulula kokulungiswa kwemveliso ngokusekelwe kwixabiso / ukuqwalaselwa kokusebenza.
