Cellulose, hydroxyethyl ether (MW 1000000)
Hydroxyethyl cellulose(HEC) he polymer hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose ma o ka hoʻokomo ʻana i nā hui hydroxyethyl. ʻO ke kaumaha molekala (MW) i ʻōlelo ʻia, 1000000, e hōʻike ana i kahi ʻano kaumaha molekala kiʻekiʻe. Eia kahi hiʻohiʻona o ka hydroxyethyl cellulose me ke kaumaha molekala o 1000000:
Hydroxyethyl Cellulose (HEC):
- Hoʻolālā Kimia:
- HEC he cellulose derivative kahi i hoʻopili ʻia ai nā hui hydroxyethyl i nā ʻāpana anhydroglucose o ke kaulahao cellulose. Hoʻonui kēia hoʻololi i ka hoʻoheheʻe wai a me nā waiwai hana ʻē aʻe o cellulose.
- Kaumaha Molekala:
- ʻO ke kaumaha molekala i ʻōlelo ʻia o 1000000 e hōʻike ana i kahi ʻano kaumaha molekala kiʻekiʻe. Hoʻopili ke kaumaha molekala i ka viscosity, rheological properties, a me ka hana o HEC i nā noi like ʻole.
- ʻAno kino:
- ʻO ka hydroxyethyl cellulose me ke kaumaha molekala o 1000000 ka mea maʻamau i loaʻa ma ke ʻano o ka pauka keʻokeʻo a keʻokeʻo ʻole. Hiki ke hāʻawi ʻia ma ke ʻano he wai hoʻonā a hoʻopuehu paha.
- Hiki i ka wai:
- Hiki ke hoʻoheheʻe ʻia ka HEC i ka wai a hiki ke hana i nā ʻoluʻolu a me ka viscous i ka wai. Hiki ke hoʻololi ʻia ka degere o ka solubility a me ka viscosity e nā mea like me ka mahana, ka pH, a me ka ʻike.
- Nā noi:
- Mānoanoa Mānoanoa: Hoʻohana maʻamau ʻia ʻo HEC ma ke ʻano he mea mānoanoa i nā noi like ʻole, me nā pena, nā uhi, nā adhesives, a me nā huahana mālama pilikino. ʻO ka ʻokoʻa paona molekala kiʻekiʻe ka mea kūpono i ka hāʻawi ʻana i ka viscosity.
- Stabilizer: Hoʻohana ia ma ke ʻano he stabilizer i nā emulsions a me nā hoʻokuʻu ʻana, e hāʻawi ana i ka paʻa a me ka kūlike o nā ʻano.
- Mea Paʻa Wai: He mau waiwai mālama wai maikaʻi loa ka HEC, e waiwai ana ia i nā mea hana, e like me nā morta a me nā huahana i hoʻokumu ʻia i ka sima.
- ʻO nā lāʻau lapaʻau: Ma ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia ʻo HEC ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka mānoanoa i loko o nā papa papa. ʻO kona ʻano hiki ke hoʻoheheʻe ʻia i ka wai kūpono ia no nā ʻano ʻano ʻano waha.
- Nā huahana mālama pilikino: Loaʻa i loko o nā mea hoʻonaninani, shampoos, a me nā lotion, hāʻawi ʻo HEC i ka viscosity a me ka paʻa i nā ʻano hana i ka ʻoihana mālama pilikino.
- ʻOihana ʻaila a me ke kinoea: Hoʻohana ʻia ʻo HEC i ka hoʻoheheʻe ʻana i nā wai e like me ka rheology modifier a me ka wai-loss control agent.
- Ka hoʻomalu viscosity:
- Hāʻawi ke kaumaha molekala kiʻekiʻe o HEC i kona pono i ka hoʻomalu ʻana i ka viscosity. He waiwai kēia waiwai i nā noi kahi e mālama ʻia ai ka mānoanoa i makemake ʻia a i ʻole nā hiʻohiʻona kahe o kahi huahana.
- Hoʻohālikelike:
- Hoʻopili maʻamau ʻo HEC me kahi ākea o nā mea ʻē aʻe a me nā mea hoʻohui i hoʻohana mau ʻia i nā ʻoihana like ʻole. Eia nō naʻe, pono e hana ʻia ka hoʻāʻo ʻana i ka hoʻohālikelike ʻana me nā ʻāpana kikoʻī.
- Nā Kūlana Kūlana:
- Hāʻawi pinepine nā mea hana i nā kikoʻī a me nā kūlana maikaʻi no nā huahana HEC, e hōʻoiaʻiʻo ana i ka kūlike a me ka hilinaʻi i ka hana. Hiki i kēia mau maʻamau ke komo i nā pae hoʻohālikelike e pili ana i ke kaumaha molekala, ka maʻemaʻe, a me nā waiwai kūpono ʻē aʻe.
ʻO ka hydroxyethyl cellulose me ke kaumaha molekala o 1000000 he polymer versatile me nā noi like ʻole ma waena o nā ʻoihana, ʻo ia hoʻi i loko o nā ʻano hana i mea nui ka viscosity a me ka solubility wai. He mea nui ka hahai ʻana i nā kuhikuhi a me nā ʻano hana i hāʻawi ʻia e nā mea hana no nā hopena maikaʻi loa i nā noi kikoʻī.
