I-Carboxymethyl cellulose (i-Carboxymethyl cellulose) yakhiwa ngokusabela kweqembu le-hydroxyl leyunithi ye-anhydroglucose ochungechungeni lwe-cellulose neqembu le-etherification (i-chloro Z acid noma i-ethylene oxide);
Kuyi-amorphous amorphous substance engenambala encibilika emanzini, isixazululo se-alkali esinamanzi, isixazululo se-ammonia ne-cellulose, esingancibiliki kusixazululo sezinto eziphilayo kanye namafutha amaminerali;ingasetshenziswa njengokulinganisa, i-calendering kanye ne-ejenti yokuqina embonini yendwangu;
I-ejenti yokuhlela ekukhiqizeni iphepha nebhodi;
Ukumuncwa kabusha kokungcola kuma-synthetic cleaning agents;
I-agent ye-Flotation yokukhetha i-copper-nickel ne-potassium ore;
I-Viscous suspension thickener kanye ne-stabilizer lapho kubholwa imithombo kawoyela negesi;
ukwakheka kweglue kwephepha lodonga;
izingxenye ezomile zokuxuba ukwakhiwa;
Izingxenye zopende zamanzi ze-latex, njll.
IHydroxypropyl methylcellulose (Hypromellose, Cellulose) yenziwe nge-cotton cellulose emsulwa kakhulu njengento eluhlaza, efakwa etherified ngokukhethekile ngaphansi kwezimo ze-alkaline, futhi ayinazo izithako ezisebenzayo njengezitho zezilwane namafutha.Incibilika emanzini nasezilinganisweni eziningi ezipholile nezifanelekile ze-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane, njll., ayincibiliki ku-ether, i-acetone, ne-ethanol ephelele, futhi ikhukhumala ibe isixazululo se-colloidal esicacile noma esidumele kancane emanzini abandayo.Isixazululo esinamanzi sinomsebenzi ongaphezulu, ukukhanya okuphezulu nokusebenza okuzinzile.
I-HPMC inendawo ye-thermal gelation.Isixazululo se-aqueous somkhiqizo siyashiswa ukuze senze ijeli futhi sikhuphuke, bese siyancibilika ngemva kokupholisa.Izinga lokushisa le-gelation lokucaciswa okuhlukile lihlukile.I-Solubility iyahlukahluka ngokuya nge-viscosity.I-viscosity ephansi, i-solubility enkulu.Ukucaciswa okuhlukile kwe-HPMC kunomehluko othile ezimpahleni zabo.Ukuhlakazwa kwe-HPMC emanzini akuthintwa ivelu ye-pH.
