HEC no nā huahana kūikawā papa hoʻonani

ʻO ka HydroxyethylcelluloseHEChe polymer wai-soluble non-ionic i hiki ke hoʻoheheʻe ʻia i ka wai wela a me ke anuanu. Loaʻa i ka moʻo Hydroxyethylcellulose HEC kahi ākea o nā viscosities, a ʻo nā hopena wai he mau wai ʻole Newtonian āpau.

He mea hoʻohui koʻikoʻi ka Hydroxyethyl cellulose i nā huahana kemika o kēlā me kēia lā. ʻAʻole hiki iā ia ke hoʻomaikaʻi wale i ka viscosity o nā mea hoʻonani wai a emulsion paha, akā hoʻomaikaʻi pū i ka dispersion a me ke kūpaʻa o ka huʻa.

pono:
1. Loaʻa ka hydration maikaʻi loa.
2. Loaʻa kahi kūlike a me ka piha maikaʻi.
3. Waiwai hana kiʻiʻoniʻoni maikaʻi loa.
4. He hana kumukūʻai kiʻekiʻe loa kona.
5. Loaʻa iā ia kahi kekelē maikaʻi loa o ka hoʻololi ʻana e hōʻoia i ka kūpaʻa anti-mildew lōʻihi o ka huahana.

Ke kēkelē polymerization:
ʻEkolu mau hui hydroxyl ma kēlā me kēia ʻāpana anhydroglucose i loko o ka cellulose, kahi i mālama ʻia me ka alkali i loko o ka wai sodium hydroxide solution e loaʻa ai ka paʻakai sodium cellulose, a laila e hana ʻia ka hopena etherification me ka ethylene oxide e hana i ka hydroxyethyl cellulose ether. I ke kaʻina hana o ka synthesizing hydroxyethyl cellulose, hiki i ka ethylene oxide ke pani i nā hui hydroxyl ma ka cellulose, a hana i kahi hopena polymerization kaulahao me nā hui hydroxyl i nā hui i pani ʻia.

He maikaʻi loa nā waiwai hydration o ka Hydroxyethylcellulose. He laumania a like kona wai hoʻoheheʻe, me ka wai maikaʻi a me ka pae ʻana. No laila, he kūlike maikaʻi a piha nā mea hoʻonani i loaʻa ka hydroxyethyl cellulose i loko o ka pahu, a pālahalaha maʻalahi ma ka lauoho a me ka ʻili ke hoʻopili ʻia. Hoʻohana nui ʻia i nā conditioners, nā holoi kino, nā kopa wai, nā gels ʻumiʻumi a me nā foam, ka toothpaste, nā deodorants antiperspirant paʻa, nā ʻiʻo (nā pēpē a me nā pākeke), nā gels lubricating.

Ma waho aʻe o ka mālama ʻana i ka wai,hydroxyethyl celluloseLoaʻa iā ia nā waiwai hana ʻili maikaʻi loa. Ua hōʻoia ʻia ke ʻano o ka ʻili i hana ʻia i loko o kahi kūlana piha ma lalo o ke nānā ʻana i ke aniani 350x a me 3500x, a lawe mai ia i kahi ʻano ʻili laumania maikaʻi loa ke hoʻopili ʻia i nā mea hoʻonani.
