Ka ʻokoʻa ma waena o CMC a me HEMC

ʻO Carboxymethylcellulose (CMC) a me Hydroxyethyl methylcellulose (HEMC) ʻelua mau ʻano derivatives cellulose i hoʻohana mau ʻia i nā ʻano ʻoihana like ʻole, me ka ʻoihana meaʻai a me nā lāʻau lapaʻau.ʻO ka CMC a me ka HEMC he mau polymers wai-soluble i loaʻa mai ka cellulose, akā he mau waiwai like ʻole a hoʻohana ʻia no nā noi like ʻole.Ma kēia ʻatikala, e ʻimi mākou i nā ʻokoʻa ma waena o CMC a me HEMC.

Hoʻolālā Kimia
Ua like ke ano kemika o CMC a me HEMC, no ka mea, he mau hua ia o ka cellulose.Hana ʻia ʻo CMC ma ka hana ʻana i ka cellulose me ka chloroacetic acid e hana ai i nā hui carboxymethyl, ʻoiai ʻo HEMC e hana ʻia ma ka hana ʻana i ka cellulose me ka ethylene oxide a me ka methyl chloride e hana i nā hui hydroxyethyl a me methyl.

Ka hikiwawe
ʻO kekahi o nā ʻokoʻa nui ma waena o CMC a me HEMC ko lākou solubility i ka wai.Hiki ke hoʻoheheʻe ʻia ka CMC i loko o ka wai a hiki ke hana i kahi ʻoluʻolu a maʻemaʻe a hiki i nā haʻahaʻa haʻahaʻa.ʻAʻole hiki ke hoʻoheheʻe ʻia ka HEMC i ka wai ma mua o ka CMC a koi maʻamau i ka hoʻohana ʻana i ka solvent, e like me ka ethanol a i ʻole isopropyl alcohol, e hoʻoheheʻe loa.

ʻO ka viscosity
ʻO kekahi ʻokoʻa koʻikoʻi ma waena o CMC a me HEMC ko lākou viscosity.ʻO CMC ʻoi loa ka viscous a hiki ke hana i kahi hopena gel-like mānoanoa ke hoʻoheheʻe ʻia i ka wai.Hana kēia i ka CMC kūpono 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.I ka hoʻohālikelike ʻana, he haʻahaʻa haʻahaʻa ko HEMC ma mua o CMC a hoʻohana maʻamau ʻia 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 kumu pH ma mua o HEMC.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.I ka hoʻohālikelike ʻana, ʻoi aku ka paʻa o ka HEMC i ka liʻiliʻi o ka waika a hiki i ka neʻe ʻana o ka pH kaiapuni a hiki ke wāwahi i nā koina pH kiʻekiʻe.

Paʻa wela
Paʻa nā CMC a me HEMC 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 HEMC a hiki ke mālama i kāna mau waiwai i nā wela kiʻekiʻe.Hana kēia i ka CMC i mea kūpono no ka hoʻohana ʻana i nā noi kahi e komo ai nā mahana kiʻekiʻe, e like me ka hana ʻana i nā mea i kālua ʻia.ʻO ka HEMC, 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 HEMC 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 loko o ka ʻoihana lāʻau lapaʻau ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka suspending agent.Hoʻohana pinepine ʻia ʻo HEMC 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.
