Methyl cellulose CAS 9004-67-5
He whakakapinga mekameka roa te methyl cellulose mō te cellulose. Ko te taumaha ngota ngota toharite o te methyl cellulose he 10000 ki te 220000, ā, he paura mā, he matū muka rānei i te pāmahana rūma. Kāore he paitini, kāore e whakapataritari, ā, kāore e pāwera, me te kiato whanaunga kitea o te 0.35 ki te 0.55 (kiato whanaunga tūturu o te 1.26 ki te 1.30).

E whakamahia whānuitia ana te methyl cellulose i roto i te umanga hanga, pērā i te piripiri mō te sima, te moata, te tango hononga, me ētahi atu. E whakamahia ana hei kaihanga kiriata me te piripiri i roto i ngā ahumahi whakapaipai, rongoā, me te kai. E whakamahia ana hoki te methyl cellulose hei kaihanga rahi mō te tā me te tae kakahu, hei whakamarara mō ngā kapia hangai, hei kaihanga kiriata mō ngā paninga, me te whakamātotoru. Ka hangaia te alkali cellulose mai i te penupenu, ka tauhohehia ki te chloromethane, ki te dimethyl sulfate rānei i roto i te autoclave ka whakangawarihia ki te wai mahana.
I te nuinga o te wā ka tākaihia ki te 25kg/pahu, ā, ka taea hoki te whakarite i te kete.
