ʻO ka Methyl cellulose (MC) i hana ʻia mai ka huahana kūlohelohe

ʻO ka Methyl cellulose (MC) kahi mea i loaʻa mai ka cellulose, he polymer kūlohelohe ia i loaʻa i loko o nā paia cell o nā mea kanu. ʻO ka Cellulose kekahi o nā hui organik nui loa ma ka Honua, i loaʻa mua mai ka pulp lāʻau a me nā olonā pulupulu. Hoʻohui ʻia ʻo MC mai ka cellulose ma o kahi moʻo o nā hopena kemika e pili ana i ka hoʻololi ʻana o nā hui hydroxyl (-OH) i loko o ka molekole cellulose me nā hui methyl (-CH3).

ʻOiai ʻo MC ponoʻī he hui i hoʻololi ʻia e nā kemika, ʻo kāna mea maka, ʻo cellulose, ua loaʻa mai nā kumu kūlohelohe. Hiki ke hoʻokaʻawale ʻia ka Cellulose mai nā mea kanu like ʻole, me ka lāʻau, ka pulupulu, ka hemp, a me nā mea kanu fibrous ʻē aʻe. Ke hana ʻia nei ka cellulose e wehe i nā mea haumia a hoʻololi iā ia i ʻano hiki ke hoʻohana ʻia no ka hana ʻana o MC.

Ke loaʻa ka cellulose, hana ʻia ka etherification e hoʻokomo i nā hui methyl ma luna o ke kuamoʻo cellulose, e hopena ana i ka hoʻokumu ʻia ʻana o ka methyl cellulose. Pili kēia kaʻina hana i ka mālama ʻana i ka cellulose me ka hui ʻana o ka sodium hydroxide a me ka methyl chloride ma lalo o nā kūlana i kāohi ʻia.

ʻO ka methyl cellulose hopena he pauka keʻokeʻo a keʻokeʻo ʻole, ʻala ʻole, a ʻono ʻole e hiki ke hoʻoheheʻe ʻia i ka wai anuanu a hana i kahi hopena viscous. Hoʻohana nui ʻia ia ma nā ʻoihana like ʻole, me ka meaʻai, nā lāʻau lapaʻau, ka mālama pilikino, a me ke kūkulu ʻana, no kona mau waiwai mānoanoa, hoʻopaʻa, a me ke ʻano hana kiʻiʻoniʻoni.

ʻOiai he hui i hoʻololi ʻia e nā kemika ka MC, ua loaʻa mai ia mai ka cellulose kūlohelohe, e lilo ia i koho biodegradable a pili i ke kaiapuni no nā noi he nui.
