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

ʻO HEC (Hydroxyethyl Cellulose) a me HEMC (Hydroxyethyl Methyl Cellulose) nā pūhui polymers ʻelua i loaʻa mai ka cellulose, kahi polysaccharide kūlohelohe i loaʻa i nā mea kanu.Hoʻohana ʻia nā mea ʻelua e like me nā mānoanoa, stabilizers, a me emulsifiers i nā ʻano huahana like ʻole, me ka pena a me nā uhi, nā meaʻai, nā lāʻau lapaʻau, nā mea hoʻonaninani, a me nā noi ʻoihana.

ʻO ka ʻokoʻa nui ma waena o HEC a me HEMC aia i kā lākou ʻano kemika.ʻO HEC kahi mea ionic cellulose derivative, aʻo HEMC he ionic cellulose derivative.Hoʻokumu ʻia ʻo HEC me kahi hui hydroxyethyl hoʻokahi i hoʻopili ʻia i ka iwi kuamoʻo cellulose, ʻoiai ʻo HEMC he ʻelua hui hydroxyethyl i hoʻopili ʻia i ka iwi kuamoʻo cellulose.

He polymer hiki ke hoʻoheheʻe wai ʻia ka HEC i hoʻohana ʻia ma ke ʻano he mānoanoa i nā huahana like ʻole, me ka pena a me nā uhi, nā meaʻai, nā lāʻau lapaʻau, a me nā mea hoʻonaninani.Hoʻohana ʻia ia e hoʻonui i ka viscosity o kahi huahana, hoʻomaikaʻi i kona kūpaʻa, a hāʻawi i kahi ʻano maʻalahi.Hoʻohana ʻia ʻo ia ma ke ʻano he emulsifier e kōkua i ka mālama ʻana i nā meaʻai mai ka hoʻokaʻawale ʻana.

ʻO HEMC kekahi polymer hiki ke hoʻoheheʻe ʻia i ka wai i hoʻohana ʻia ma ke ʻano he mānoanoa.Hoʻohana ʻia ia i nā huahana like ʻole, me ke kūkulu ʻana, nā meaʻai, nā lāʻau lapaʻau, a me nā mea hoʻonaninani.Hoʻohana ʻia ia e hoʻonui i ka viscosity o kahi huahana, hoʻomaikaʻi i kona kūpaʻa, a hāʻawi i kahi ʻano maʻalahi.Hoʻohana ʻia ʻo ia ma ke ʻano he emulsifier e kōkua i ka mālama ʻana i nā meaʻai mai ka hoʻokaʻawale ʻana.

Hoʻohana maʻamau ʻia ʻo HEC i ka pena a me nā huahana uhi, aʻo ka HEMC e hoʻohana pinepine ʻia i ke kūkulu ʻana a me nā mea hoʻonaninani.ʻOi aku ka maikaʻi o ka HEC i ka hoʻonui ʻana i ka viscosity o kahi huahana ma mua o ka HEMC, a ʻoi aku ka paʻa o ka ʻakika a me ka alkaline.ʻOi aku ka maikaʻi o ka HEMC i ka hāʻawi ʻana i kahi ʻano laulima i kahi huahana ma mua o HEC, a ʻoi aku ka paʻa i nā wela kiʻekiʻe.

I ka hōʻuluʻulu ʻana, ʻo ka ʻokoʻa nui ma waena o HEC a me HEMC aia i loko o kā lākou hana kemika.ʻO HEC kahi mea ionic cellulose derivative, aʻo HEMC he ionic cellulose derivative.Hoʻohana pinepine ʻia ʻo HEC i ka pena a me nā uhi, nā huahana detergent, ʻoiai ʻoi aku ka maʻamau o HEMC i ke kūkulu ʻana a me nā mea hoʻonaninani.ʻOi aku ka maikaʻi o ka HEC i ka hoʻonui ʻana i ka viscosity o kahi huahana, ʻoiai ʻoi aku ka maikaʻi o HEMC i ka hāʻawi ʻana i kahi ʻano maʻalahi.
