ʻO Carboxymethylcellulose (CMC) a me ka starch nā polysaccharides, akā he mau hale like ʻole ko lākou, waiwai a me nā noi.
Hui molekala:
1. Carboxymethylcellulose (CMC):
ʻO Carboxymethylcellulose he mea ia o ka cellulose, he polymer linear i haku ʻia me nā ʻāpana glucose i hoʻopili ʻia e nā paʻa β-1,4-glycosidic.Hoʻololi ka cellulose i ka hoʻokomo ʻana i nā hui carboxymethyl ma o ka etherification, e hana ana i ka carboxymethylcellulose.Hana ka hui carboxymethyl i ka wai CMC a hāʻawi i nā waiwai kūʻokoʻa polymer.
2. Mākaʻikaʻi:
ʻO ka starch he waiʻaʻaʻaʻa i haku ʻia me nā ʻāpana glucose i hoʻopili ʻia e nā paʻa α-1,4-glycosidic.He polymer maoli ia i loaʻa i nā mea kanu i hoʻohana ʻia ma ke ʻano he pūhui mālama ikehu.Hoʻokumu ʻia nā ʻano molekole starch i ʻelua ʻano polymers glucose: amylose (nā kaulahao pololei) a me ka amylopectin (nā hale kaulahao lālā).
Nā waiwai kino:
1. Carboxymethylcellulose (CMC):
Solubility: Hiki ke hoʻoheheʻe ʻia ka CMC ma muli o ka loaʻa ʻana o nā hui carboxymethyl.
Viscosity: Hōʻike ia i ka viscosity kiʻekiʻe i ka hopena, e waiwai ai ia i nā noi like ʻole e like me ka hoʻoili ʻana i ka meaʻai a me nā lāʻau lapaʻau.
Mākaʻikaʻi: Akaka maʻamau nā hāʻina CMC.
2. Mākaʻikaʻi:
Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia ka starch maoli i ka wai.Pono ka gelatinization (hoʻomehana i ka wai) i mea e hemo ai.
Viscosity: He viscosity ka pāpaʻi starch, akā ʻoi aku ka haʻahaʻa ma mua o CMC.
Mākaʻikaʻi: He opaque ka pāpaʻi starch, a ʻokoʻa paha ke ʻano o ka opacity ma muli o ke ʻano o ka starch.
kumu:
1. Carboxymethylcellulose (CMC):
Hana ʻia ka CMC mai ka cellulose mai nā kumu mea kanu e like me ka pulp lāʻau a i ʻole ka pulupulu.
2. Mākaʻikaʻi:
Nui nā mea kanu e like me ke kulina, ka palaoa, ka ʻuala a me ka raiki i ka mākiko.He mea nui ia i nā meaʻai nui.
Kaʻina hana:
1. Carboxymethylcellulose (CMC):
ʻO ka hana ʻana o CMC e pili ana i ka hopena etherification o cellulose me ka waikawa chloroacetic i loko o kahi ʻano alkaline.ʻO kēia ka hopena i ka hoʻololi ʻana o nā pūʻulu hydroxyl i cellulose me nā hui carboxymethyl.
2. Mākaʻikaʻi:
ʻO ka wehe ʻana i ka starch ka wāwahi ʻana i nā mea kanu a me ka hoʻokaʻawale ʻana i nā granules starch.Hiki i ka starch i unuhi ʻia ke hana i nā kaʻina like ʻole, me ka hoʻololi a me ka gelatinization, e loaʻa ai nā waiwai i makemake ʻia.
Ke kumu a me ka hoʻohana ʻana:
1. Carboxymethylcellulose (CMC):
ʻOihana meaʻai: Hoʻohana ʻia ʻo CMC ma ke ʻano he mānoanoa, stabilizer a me ka emulsifier i nā meaʻai like ʻole.
ʻO nā lāʻau lapaʻau: Ma muli o kāna mau mea paʻa a me ka wehe ʻana, ʻike ʻia ka hoʻohana ʻana i nā ʻano lāʻau lapaʻau.
ʻO ka ʻaila ʻaila: Hoʻohana ʻia ʻo CMC i nā wai wili ʻaila e hoʻomalu i ka rheology.
2. Mākaʻikaʻi:
ʻOihana meaʻai: ʻO Starch ka mea nui o nā meaʻai he nui a hoʻohana ʻia ma ke ʻano he mea mānoanoa, gelling agent a stabilizer.
ʻOihana lole: Hoʻohana ʻia ka starch i ka nui o ka lole e hāʻawi i ka ʻoʻoleʻa i nā lole.
ʻOihana pepa: Hoʻohana ʻia ka starch i ka hana pepa e hoʻonui i ka ikaika o ka pepa a hoʻomaikaʻi i nā waiwai o ka ʻili.
ʻOiai ʻo CMC a me ka starch he polysaccharides, he ʻokoʻa ko lākou i ka hoʻohui ʻana i ka molekala, nā waiwai kino, nā kumu, nā kaʻina hana a me nā noi.ʻO ka CMC ka wai-soluble a me ka viscous nui a makemake pinepine ʻia i nā noi e koi ana i kēia mau waiwai, ʻoiai ʻo ka starch he polysaccharide versatile i hoʻohana nui ʻia i ka ʻoihana meaʻai, textile a me ka pepa.He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau ʻokoʻa i ke koho ʻana i ka polymer kūpono no nā noi ʻoihana a me nā ʻoihana.
