He aha ka ʻokoʻa ma waena o HEC a me MHEC?

ʻO HEC a me MHEC nā ʻano mea ʻelua o ka cellulose-based polymers i hoʻohana ʻia i nā ʻano noi like ʻole, e like me nā mānoanoa, stabilizers, a me nā emulsifiers i nā huahana meaʻai, a me nā huahana lāʻau a me nā mea hoʻonaninani.ʻO ka ʻokoʻa nui ma waena o nā mea ʻelua ʻo HEC he hydroxyethyl cellulose, ʻoiai ʻo MHEC he methyl hydroxyethyl cellulose.

He polymer hiki ke hoʻoheheʻe wai ka HEC i loaʻa mai ka cellulose, he polysaccharide kūlohelohe i loaʻa i nā mea kanu.Hoʻokumu ʻia ia me kahi kaulahao laina o nā molekole glucose me kahi hui hydroxyethyl i hoʻopili ʻia i ka hopena o kēlā me kēia mole.Hoʻohana ʻia ʻo HEC cellulose ma ke ʻano he mānoanoa, stabilizer, a me ka emulsifier i nā huahana meaʻai, a me nā huahana lāʻau lapaʻau a me nā mea hoʻonaninani.Hoʻohana ʻia ia i ka hana pepa a me ka paʻi ʻana, a me ka hana ʻana i nā mea hoʻopili a me nā uhi.

ʻO MHEC kahi ʻano hoʻololi o HEC cellulose kahi i hoʻololi ʻia ai ka hui hydroxyethyl me kahi hui methyl.Hoʻonui kēia hoʻololi i ka hydrophobicity o ka polymer, e ʻoi aku ka pale ʻana i nā mea hiki ke hoʻoheheʻe wai.Hoʻohana ʻia ʻo MHEC i nā ʻano noi like ʻole, e like me ka mānoanoa, stabilizer, a me ka emulsifier i nā huahana meaʻai, a me nā huahana lāʻau lapaʻau a me nā mea hoʻonaninani.Hoʻohana ʻia ia i ka hana pepa a me ka paʻi ʻana, a me ka hana ʻana i nā mea hoʻopili a me nā uhi.

I ka hōʻuluʻulu ʻana, ʻo ka ʻokoʻa nui ma waena o HEC cellulose a me MHEC ʻo HEC he hydroxyethyl cellulose, ʻoiai ʻo MHEC he methyl hydroxyethyl cellulose.Hoʻohana ʻia nā mea ʻelua i nā noi like ʻole, e like me nā mānoanoa, stabilizers, a me nā emulsifiers i nā huahana meaʻai, a me nā huahana lāʻau lapaʻau a me nā mea hoʻonaninani.
