I-cellulose ether

Ama-cellulose ethers iyiqembu lokuphuma kokunye okushintshiwe ngamakhemikhali kwe-cellulose, lapho amaqembu e-hydroxyl (-OH) yama-molecule e-cellulose ethathelwa indawo ngamaqembu e-ether (-OR). Lezi zinguquko zithuthukisa izakhiwo ze-cellulose, ziyenze ibe usizo kakhulu ezimbonini ezihlukahlukene.

I-Cellulose Ether ibonise ukuthi iwusizo kakhulu ama-polymers asekelwe emvelo, ukuthola isicelo ezindaweni ezihlanganisa ukudla, imikhiqizo yokunakekelwa komuntu siqu, amakhemikhali ensimu kawoyela, ukwakhiwa, iphepha, izinto zokunamathisela, nezindwangu.;

Anenani elikhethekile ekusetshenzisweni kwemithi ngenxa yezici ezihlanganisa amazinga okushisa aphezulu okushintsha kwezingilazi, ukuzinza kwamakhemikhali aphezulu kanye nesithombe samakhemikhali, ukuncibilika, ikristalu elinganiselwe, amandla okubopha i-hydrogen, nobuthi obuphansi.;

Mayelana nobuthi, ama-cellulose ether empeleni awanawo amandla okungena ngama-enterocyte asemathunjini futhi amaningi asevele akhiwe agunyazwe i-US Food and Drug Administration.

Ama-cellulose ethers ama-polymers ancibilika emanzini akhiqizwa ukuguqulwa kwamakhemikhali e-cellulose.;

Ama-ethers amakhulu e-cellulose ezentengiselwano afaka i-carboxymethylcellulose (CMC), i-methylcellulose (MC) kanye nokuphuma okufana ne-hydroxypropyl methylcellulose (HPMC) ne-hydroxyethyl methylcellulose (HEMC), i-hydroxyethylcellulose (HEC) kanye nokuphuma okufana ne-ethyl hydroxyethylHEcellulose (methylEthyylHEcellulose) (MEHEC), hydroxypropyl cellulose (HPC), kanye ne-ethylcellulose (EC).

Ama-cellulose etherszisebenza njengezinzinzisi, ama-thickeners, kanye nezilungisi ze-viscosity ezimbonini eziningi, okuhlanganisa ukudla, ezemithi, imikhiqizo yokunakekela abantu, amakhemikhali ensimu kawoyela, ukwakhiwa, iphepha, izinto zokunamathisela, nezindwangu.;

Ezintweni ezikhethiwe, zincintisana zodwa kanye nama-polymers okwenziwa ancibilika emanzini (i-polyvinyl alcohol, i-polyurethane associative thickeners, i-polyacrylates) nama-polymers emvelo ancibilika emanzini (i-xanthan gum, i-carrageenan, ushingamu kabhontshisi wezinkumbi).

Ukukhethwa kwe-polymer kunqunywa ukuhwebelana kwentengo/ukusebenza, ukutholakala, kanye nokuba lula kokulungiswa kabusha komkhiqizo ngokusekelwe ekucatshangelweni kwentengo/kokusebenza.

I-Cellulose ether iyimpuphu ye-cellulose ether ekhiqizwa nge-wood fibre noma i-fiber kakotini ecolisisiwe njengezinto zokusetshenziswa eziyinhloko, ngemva kokwelashwa ngamakhemikhali kanye nokusabela kwe-etherifying agents njenge-chlorinated ethylene, i-chlorinated propylene ne-ethylene ene-oxidized.

Inqubo yokukhiqiza ye-cellulose ether iyinkimbinkimbi.;

I-cellulose ether iqala ngokukhishwa kwe-cellulose kukotini noma okhunini, bese ishintsha ibe i-alkaline cellulose ngemva kokwengeza i-sodium hydroxide kanye nokusabela kwamakhemikhali (isixazululo se-alkaline).

Ngaphansi kwesenzo se-etherifying agents (i-etherification reaction), ama-cellulose ethers akhiqizwa ku-cellulose ye-alkali ngezinqubo ezinjengokugeza ngamanzi, ukomiswa nokugaya.

I-cellulose ethers iyisengezo sokusebenza esibaluleke kakhulu sezisetshenziswa zesimanje zikasimende kanye ne-gypsum-based construction.;

I-Cellulose ether ithuthukisa ukufometha, ithuthukisa ukusebenza kahle, ikhuphula ukuphuma, ukumbozwa futhi yehlise ukumosha.

I-cellulose ether inikeza izinzuzo eziningi ngesikhathi esisodwa; Kuncike emisebenzini efana nokugcinwa kwamanzi, ukugcotshwa, ukwanda kokumelana ne-crack, anti-slip, ukwandisa ukunamathela kanye nokwelula isikhathi sokuvula.;

I-Cellulose ether isebenza ngombono wokuqala, ikhwalithi yokulawula eqinile, ukuphatha kanye nesevisi yamakhasimende ekilasi lokuqala ku-R&D.

Ama-cellulose ether angama-high-purity, ama-polymers ancibilikayo, angewona ama-ionic aklanyelwe ukusetshenziswa njengezinsiza zokugcina amanzi, ama-ejenti okuqina kanye nokwenza ifilimu, ama-colloid avikelayo, ama-agent amisayo kanye nama-emulsifying, ama-binders kanye nama-stabilizers.

Esuselwe ku-cellulose, insiza yemvelo, echichima futhi evuselelekayo, ama-Cellulose ethers asetshenziswe iminyaka engaphezu kwengu-50 ukuthuthukisa ukusebenza komkhiqizo ekunakekelweni komuntu siqu, ekusetshenzisweni kwemithi nokudla.
