Methyl celluloseguud ahaan waa soo gaabinta sodium carboxymethyl cellulose, kaas oo iska leh nooc ka mid ah xarun polyanionic oo leh milmi biyo wanaagsan. Waxaa ka mid ah, cellulose methyl inta badan waxaa ka mid ah methyl cellulose m450, modified methyl cellulose, cuntada Fasalka methyl cellulose, hydroxymethyl cellulose, iwm, waxaa inta badan loo isticmaalaa in tiro balaadhan oo ah warshadaha, inta badan loo isticmaalo in dhismaha, ceramics, cuntada, baytariyada, waraaqaha, waraaqaha, dawooyinka, macdan qodista, qodista saliidda. Waxaa xusid mudan in berrinka sibidhka, methylcellulose uu leeyahay saameyn dib u dhac ah oo muuqda oo ku saabsan isku dhafka hoobiye, taas oo sidoo kale ay sabab u tahay qaabka gaarka ah ee methylcellulose.
Silsilad dheer oo lagu beddelay cellulose, sodium carboxymethylcellulose lafteedu waxay leedahay qiyaastii 27% ~ 32% kooxaheeda hydroxyl qaab kooxo methoxy ah, iyo heerka polymerization ee darajooyin kala duwansodium carboxymethylcellulosesidoo kale waa ka duwan yahay. Miisaanka molecular ee inta badan ku lug leh wuxuu u dhexeeyaa 10,000 ilaa 220,000 Da, heerka ugu weyn ee bedelkuna waa tirada celceliska kooxaha methoxy, kuwaas oo ah unugyo anhydroglucose kala duwan oo ku xiran silsiladda.
Sodium carboxymethyl cellulose ayaa hadda si weyn loogu isticmaalaa qaar ka mid ah diyaarinta jirka la mariyo, iyo sidoo kale waxyaalaha la isku qurxiyo iyo methyl cellulose-fasalka cuntada, kuwaas oo guud ahaan aan sun ahayn, non-sensitizing, iyo aan xanaaqin. Methyl cellulose Su waa walxo aan kaloori ahayn,
