He aha ka ʻokoʻa ma waena o CMC a me MC?

ʻO CMC a me MC nā mea ʻelua cellulose i hoʻohana mau ʻia e like me nā mānoanoa, nā mea hoʻopaʻa, a me nā stabilizers i nā noi like ʻole, me ka meaʻai, lāʻau lapaʻau, a me nā ʻoihana mālama pilikino.Eia naʻe, aia kekahi mau ʻokoʻa ma waena o nā mea ʻelua e pono e ʻike.

ʻO CMC, a i ʻole Carboxymethyl Cellulose, he polymer hoʻoheheʻe wai i loaʻa mai ka cellulose.Hana ʻia ia ma ka hana ʻana i ka cellulose me ka sodium chloroacetate a me ka hoʻololi ʻana i kekahi o nā pūʻulu hydroxyl ma ka cellulose i nā hui carboxymethyl.Hoʻohana nui ʻia ʻo CMC i nā huahana meaʻai, e like me nā mea i hoʻomoʻa ʻia, nā huahana waiu, a me nā ʻuala, a me nā huahana mālama pilikino a me nā lāʻau lapaʻau.

ʻO MC, a i ʻole Methyl Cellulose, he polymer hoʻoheheʻe wai i loaʻa mai ka cellulose.Hana ʻia ia ma ka hana ʻana i ka cellulose me ka methyl chloride a me ka hoʻololi ʻana i kekahi o nā pūʻulu hydroxyl ma ka cellulose i mau pūʻulu methyl ether.Hoʻohana ʻia ʻo MC ma ke ʻano he mānoanoa, binder, a me ka emulsifier i nā noi like ʻole, me nā huahana meaʻai, e like me nā meaʻai, nā lole, a me nā mea ʻai maloʻo, a me nā lāʻau lapaʻau a me nā huahana mālama pilikino.

ʻO kahi ʻokoʻa koʻikoʻi ma waena o CMC a me MC ʻo kā lākou ʻano solubility.ʻOi aku ka maʻalahi o ka hoʻoheheʻe ʻana o ka CMC i ka wai ma mua o ka MC, a hiki iā ia ke hana i kahi hopena akaka, ʻeleʻele ma nā haʻahaʻa haʻahaʻa.ʻO MC, ma ka ʻaoʻao ʻē aʻe, koi maʻamau i nā ʻike kiʻekiʻe a me / a i ʻole ka wela e hoʻoheheʻe piha i ka wai, a ʻoi aku ka opaque a i ʻole ke ao.

ʻO kahi ʻokoʻa ʻē aʻe kā lākou hana i nā kūlana pH like ʻole.ʻOi aku ka paʻa o ka CMC i nā kūlana acidic a hiki ke ʻae i kahi ākea pH ākea ma mua o MC, hiki ke wāwahi a nalowale kona mau waiwai mānoanoa i nā kaiapuni acidic.

ʻO ka CMC a me ka MC he mau mea waiwai cellulose i loaʻa nā waiwai kūpono no nā noi like ʻole.ʻO ke koho o ka mea e hoʻohana ai e hilinaʻi ia i nā koi kikoʻī o ka noi a me nā ʻano hana i makemake ʻia.
