Methyl cellulose (MC) i hangaia mai i te hua taiao

Ko te Methyl cellulose (MC) he mea hanga mai i te cellulose, he pūmua tūturu e kitea ana i roto i ngā pakitara pūtau o ngā tipu. Ko te Cellulose tētahi o ngā matū waro tino nui o te Ao, i ahu mai i te penupenu rakau me ngā muka miro. Ka hangaia te MC mai i te cellulose mā roto i tētahi raupapa o ngā tauhohenga matū e uru ana ki te whakakapinga o ngā rōpū hydroxyl (-OH) i roto i te ngota cellulose ki ngā rōpū methyl (-CH3).

Ahakoa he matū kua whakarerekētia te MC, ko tōna rauemi mata, te cellulose, i ahu mai i ngā puna taiao. Ka taea te tango i te cellulose mai i ngā momo tipu, tae atu ki te rakau, te miro, te hemp, me ētahi atu tipu muka. Ka tukatukahia te cellulose hei tango i ngā paru me te huri hei āhua e taea ai te hanga MC.

Kia whiwhihia te cellulose, ka pāngia e te etherification hei whakauru i ngā rōpū methyl ki te tuara o te cellulose, ka hua ake te hanganga o te methyl cellulose. Ko tēnei tukanga ko te rongoā i te cellulose ki te ranunga o te hauwai konutai me te methyl chloride i raro i ngā āhuatanga whakahaeretia.

Ko te methyl cellulose ka puta mai he paura mā ki te mā-parauri, kāore he kakara, kāore hoki he reka, ka wairewa ki te wai matao, ā, ka hanga he wairewa matotoru. He whānuitia te whakamahinga i roto i ngā momo ahumahi, tae atu ki te kai, te rongoā, te tiaki whaiaro, me te hanga whare, mō ōna āhuatanga whakamātotoru, whakaū, me te hanga kiriata.

Ahakoa he matū kua whakarerekētia te MC, i ahu mai i te cellulose tūturu, ā, he mea pirau, he mea hoki e pai ana mō te taiao mō ngā mahi maha.
