ʻOkoʻa ma waena o CMC a me MHEC

ʻO Carboxymethylcellulose (CMC) a me Methyl hydroxyethyl cellulose (MHEC) ʻelua mau ʻano maʻamau o ka cellulose derivatives i hoʻohana nui ʻia i nā ʻoihana like ʻole. Hāʻawi lākou i kekahi mau mea like i ko lākou ʻano kemika a me nā waiwai kino, akā loaʻa iā lākou kekahi mau ʻokoʻa koʻikoʻi e kūpono ai i nā noi like ʻole. Ma kēia ʻatikala, e ʻimi mākou i nā ʻokoʻa ma waena o CMC a me MHEC.

Hoʻolālā Kimia
ʻO ka CMC a me ka MHEC nā derivatives cellulose he polymers wai-soluble. Loaʻa ka CMC mai ka cellulose ma ka hoʻopili ʻana iā ia me ka waikawa chloroacetic e hoʻolauna i nā hui carboxymethyl, ʻoiai ʻo MHEC e loaʻa mai ka cellulose ma ka hana ʻana me ka ethylene oxide a me ka methyl chloride e hoʻokomo i nā hui methyl a me hydroxyethyl.

Ka hoʻoheheʻe
ʻO kekahi o nā ʻokoʻa nui ma waena o CMC a me MHEC ko lākou solubility i ka wai. Hiki ke hoʻoheheʻe ʻia ʻo CMC i ka wai a hiki ke hana i kahi hopena akaka a ʻoi aku ka haʻahaʻa. ʻAʻole hiki ke hoʻoheheʻe ʻia ka MHEC i ka wai ma mua o ka CMC a koi pinepine i ka hoʻohana ʻana i ka solvent, e like me ka ethanol a i ʻole isopropyl alcohol, e hoʻoheheʻe loa.

Viscosity
Hiki i ka CMC a me ka MHEC ke hoʻonui i ka viscosity. Eia nō naʻe, ʻoi aku ka nui o ka viscosity CMC ma mua o MHEC, a hiki ke hana i kahi ʻano like me ka gel i ka wā i hoʻoheheʻe ʻia i ka wai. He mea kūpono kēia i ka CMC no ka hoʻohana ʻana i nā noi kahi e koi ʻia ai ka mānoanoa a i ʻole ka gelling, e like me ka ʻoihana meaʻai no ka hana ʻana i nā ʻuala a me nā lole. ʻO MHEC, ma ka ʻaoʻao ʻē aʻe, he haʻahaʻa haʻahaʻa ka viscosity ma mua o CMC a hoʻohana maʻamau ma ke ʻano he mānoanoa a i ʻole rheology modifier i nā noi kahi e koi ʻia ai kahi hopena liʻiliʻi liʻiliʻi.

pH Paʻa
ʻOi aku ka paʻa o CMC ma luna o kahi ākea o nā waiwai pH ma mua o MHEC. Paʻa ʻo CMC i nā ʻāpana acidic a me ka alkaline, kahi e kūpono ai no ka hoʻohana ʻana i ka ʻoihana meaʻai, kahi e ʻokoʻa ai nā waiwai pH. ʻO ka hoʻohālikelike, ʻoi aku ka paʻa o ka MHEC i ka ʻakika liʻiliʻi i nā kaiapuni pH kūʻokoʻa a hiki ke wāwahi i nā koina pH kiʻekiʻe.

Paʻa wela
Paʻa ka CMC a me ka MHEC ma luna o kahi ākea o nā mahana, akā aia nā ʻokoʻa i ko lākou kūpaʻa wela. ʻOi aku ka paʻa o ka CMC ma mua o MHEC a hiki ke mālama i kāna mau waiwai i nā wela kiʻekiʻe. Hana kēia i ka CMC kūpono no ka hoʻohana ʻana i nā noi kahi e komo ai nā mahana kiʻekiʻe, e like me ka hana ʻana i nā meaʻai bakena. ʻO MHEC, ma ka ʻaoʻao ʻē aʻe, he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ma mua o CMC a hiki ke wāwahi i nā wela kiʻekiʻe.

Nā noi
Hoʻohana ʻia ʻo CMC a me MHEC i nā noi like ʻole ma nā ʻoihana like ʻole. Hoʻohana pinepine ʻia ʻo CMC ma ke ʻano he mānoanoa, stabilizer, a me ka emulsifier i ka ʻoihana meaʻai no nā huahana e like me ka ice cream, sauces, a me nā lole. Hoʻohana ʻia ia i ka ʻoihana lāʻau lapaʻau ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka suspending agent. Hoʻohana maʻamau ʻo MHEC ma ke ʻano he mānoanoa, binder, a me rheology modifier i ka ʻoihana kūkulu hale no nā huahana e like me nā pena, nā uhi, a me nā mea hoʻopili. Hoʻohana ʻia ia i ka ʻoihana lāʻau lapaʻau ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka mea hoʻokuʻu hoʻomau.

I ka hopena, ʻo CMC a me MHEC ʻelua mau mea hoʻoheheʻe cellulose e kaʻana like i ko lākou ʻano kemika a me nā waiwai kino akā loaʻa nā ʻokoʻa ʻokoʻa i ko lākou solubility, viscosity, pH stability, thermal stability, a me nā noi.
