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 meaʻai i hoʻomoʻa ʻia, nā huahana waiu, a me nā kīʻaha, 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 emulsifier i nā noi like ʻole, e like 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 ʻia ʻana o ka CMC i ka wai ma mua o ka MC, a hiki iā ia ke hana i kahi hoʻonā akaka a viscous 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 ʻia i ka wai, a ʻoi aku ka opaque a i ʻole ke ao.

ʻO kekahi ʻokoʻa ʻo kā lākou ʻano 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 iā ia ke wāwahi a nalowale kona mau waiwai mānoanoa i nā kaiapuni waikawa.

ʻO ka CMC a me ka MC he mau mea waiwai cellulose i loaʻa i nā waiwai pono 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.
