Ukunyibilika kweeMveliso zeMethyl Cellulose

Ukunyibilika kweeMveliso zeMethyl Cellulose

I-Methyl cellulose yipolymer enyibilikayo emanzini esetyenziswa ngokubanzi kwizicelo ezahlukeneyo zemizi-mveliso. Ukunyibilika kweemveliso ze-methyl cellulose kuxhomekeke kwizinto ezahlukeneyo, kubandakanywa iqondo lokutshintshwa, ubunzima bemolekyuli, ubushushu, kunye ne-pH.

Iimveliso ze-Methyl cellulose ezinezinga eliphantsi lokutshintshwa kunye nobunzima obuphantsi be-molecular bunyibilika ngakumbi emanzini kuneemveliso ezinomgangatho ophezulu wokutshintshwa kunye nobunzima obuphezulu be-molecular. Iimveliso ze-Methyl ze-cellulose ezinezinga eliphezulu lokutshintshela kunye nobunzima obuphezulu be-molecular bunokufuna amaqondo okushisa aphezulu okanye ixesha elide lokuxuba ukuchithwa ngokupheleleyo emanzini.

I-pH yesisombululo inokuchaphazela ukunyibilika kwe-methyl cellulose. Iimveliso zeMethyl cellulose zinyibilika kakhulu kwizisombululo ezingathathi hlangothi okanye ezineasidi encinci. Kumaxabiso aphezulu e-pH, ukunyibilika kwe-methyl cellulose kuncipha. Oku kungenxa ye-ionization yamaqela e-hydroxyl kwi-backbone ye-cellulose, enokunciphisa amandla eemolekyuli zamanzi ukusebenzisana namatyathanga e-polymer.

Ukongeza emanzini, iimveliso ze-methyl cellulose zinokunyibilika kwezinye izinyibilikisi eziphilayo, ezinjenge-ethanol, i-methanol, kunye ne-acetone. Nangona kunjalo, ukunyibilika kwe-methyl cellulose kwezi zinyibilikisiweyo kulinganiselwe kwaye kuxhomekeke kwinqanaba lokutshintshwa kunye nobunzima bemolekyuli yemveliso.

Ukuqukumbela, ukunyibilika kweemveliso ze-methyl cellulose kuxhomekeke kwizinto ezahlukeneyo, kubandakanya inqanaba lokutshintsha, ubunzima bemolekyuli, ubushushu, kunye ne-pH. Iimveliso ze-Methyl ze-cellulose ezinezinga eliphantsi lokutshintshwa kunye nobunzima obuphantsi be-molecular bunyibilika ngakumbi emanzini, ngelixa iimveliso ezinomgangatho ophezulu wokutshintshwa kunye nobunzima obuphezulu be-molecular inokufuna ukushisa okuphezulu okanye ixesha elide lokuxuba ukuchithwa ngokupheleleyo. Iimveliso ze-Methyl cellulose zezona zinyibilikayo kwizisombululo ezingathathi hlangothi okanye ezine-asidi encinci, kwaye zinokunyibilika kwezinye izinyibilikisi zendalo, kodwa ukunyibilika kwezi zinyibilikisi kulinganiselwe.
