ʻO ka Hydroxyethylcellulose (HEC) kahi mānoanoa maʻamau a hoʻohana nui ʻia i nā ʻoihana like ʻole.Loaʻa kēia pūhui mai ka cellulose, kahi polymer maoli i loaʻa i ka nui i loko o nā paia o nā mea kanu.ʻO nā waiwai kūʻokoʻa o HEC he mea kūpono ia no ka mānoanoa o nā huahana like ʻole, mai nā huahana mālama pilikino a i nā hana ʻenehana.
ʻIkepili Cellulose
ʻO ka Cellulose kahi waiʻaʻaʻa paʻakikī i haku ʻia me nā kaulahao laina o nā molekole glucose i hoʻopili ʻia e nā paʻa β-1,4-glycosidic.ʻO ia ka mea hana nui o nā paia o nā mea kanu, e hāʻawi ana i ka rigidity a me ka ikaika i nā mea kanu.Eia naʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia kona ʻano maoli a ua kaupalena ʻia ka hana no kekahi mau noi.
nā mea hoʻopuka cellulose
I mea e hoʻonui ai i ka hana o ka cellulose, ua hoʻohui ʻia nā ʻano derivatives e ka hoʻololi ʻana i kona ʻano.ʻO kekahi o ia derivative he hydroxyethyl cellulose (HEC), kahi i hoʻokomo ʻia ai nā hui hydroxyethyl i loko o ka iwi kuamoʻo.Hāʻawi kēia hoʻololi i nā waiwai kūʻokoʻa HEC, e hoʻoheheʻe ʻia i ka wai a maikaʻi loa e like me ka mānoanoa.
Nā hiʻohiʻona o HEC
Ka hikiwawe
ʻO kekahi o nā hiʻohiʻona nui o ka HEC ʻo kona hiki ke hoʻoheheʻe wai.ʻAʻole like me ka cellulose maoli, hemo maʻalahi ʻo HEC i ka wai, e hana ana i kahi hopena maʻemaʻe.He mea maʻalahi kēia hoʻoheheʻe ʻana i ka hoʻohui ʻana i nā ʻano hana like ʻole.
Rheological waiwai
Hōʻike ka HEC i ka hana pseudoplastic a i ʻole ka shear-thinning, ʻo ia hoʻi, e emi ana kona viscosity ma lalo o ke koʻikoʻi shear a piʻi hou ma hope o ka hoʻomaha ʻana o ke kaumaha.He mea koʻikoʻi kēia rheology no nā noi e pono ai ka maʻalahi o ka hoʻolaha ʻana a i ʻole ka ninini ʻana, e like me ka hana ʻana o nā pena, nā mea hoʻopili a me nā huahana mālama pilikino.
paʻa pH
He kūpaʻa ʻo HEC ma luna o kahi ākea pH ākea, kūpono ia no ka hoʻohana ʻana i nā mea hoʻohālikelike acidic, neutral a alkaline.Ua hāʻawi kēia versatility i kona hoʻohana ākea ʻana i nā ʻoihana like ʻole me ka cosmetics, pharmaceuticals a me ka meaʻai.
Na noi o HEC
nā huahana mālama pilikino
Nā Shampoos a me nā Conditioners: Hoʻohana pinepine ʻia ʻo HEC e hoʻopololei i nā huahana mālama lauoho, e hāʻawi ana i ka viscosity kūpono a hoʻomaikaʻi i ke ʻano holoʻokoʻa.
Nā Kilika a me nā Lotions: I loko o nā hana mālama ʻili, kōkua ʻo HEC e hoʻokō i ka kūlike i makemake ʻia a hoʻonui i ka hoʻolaha ʻana o nā ʻaila a me nā lotions.
Toothpaste: ʻO kāna ʻano pseudoplastic e hoʻomaʻamaʻa i ka hoʻopili ʻana i ka niho niho e hiki ai ke maʻalahi i ka hāʻawi ʻana a me ka laha ʻana i ka wā o ka palaki ʻana.
Nā Pena a me nā Pena
Pena Latex: Kōkua ʻo HEC i ka hoʻonui ʻana i ka viscosity a me ka paʻa o ka pena latex, e hōʻoiaʻiʻo ana i ka hoʻohana ʻana ma ka ʻili.
Adhesives: Ma nā hoʻopili hoʻopili, kōkua ʻo HEC i ka mālama ʻana i ka viscosity a hoʻomaikaʻi i nā waiwai pili.
lāʻau lapaʻau
Hoʻokuʻu waha: Hoʻohana ʻia ʻo HEC e mānoanoa i nā hoʻokuʻu waha e hāʻawi i kahi ʻano paʻa a paʻa no ka hui lāʻau.
ʻO nā gels topical: ʻO ka solubility o HEC i ka wai kūpono ia no ka hoʻokumu ʻana i nā gels topical, e hōʻoia i ka maʻalahi o ka noi a me ka absorption.
ʻoihana meaʻai
ʻO nā kīʻaha a me nā lole: Hoʻohana ʻia ʻo HEC e mānoanoa i nā ʻuala a me nā lole, e hoʻomaikaʻi i ko lākou ʻano a me ka waha.
Nā Huahana Baked: Ma kekahi mau mea hoʻomaʻamaʻa bakena, kōkua ʻo HEC i ka mānoanoa o nā paila a me nā paila.
Hana a me ka mana o ka maikaʻi
hoʻohuihui
Hana ʻia ka HEC e ka etherification o cellulose me ka ethylene oxide ma lalo o nā kūlana i hoʻomalu ʻia.Hiki ke hoʻololi ʻia ke kiʻekiʻe o ka hoʻololi ʻana (DS) o ka hui hydroxyethyl i ka wā o ke kaʻina hana synthesis, no laila e pili ana i ka hana hope o HEC.
QC
He mea koʻikoʻi nā ana hoʻomalu maikaʻi e hōʻoia i ka hana mau o HEC ma nā ʻano noi like ʻole.E nānā pono ʻia nā ʻāpana e like me ke kaumaha molecular, degere o ka hoʻololi ʻana a me ka maʻemaʻe i ka wā o ke kaʻina hana.
noonoo kaiapuni
E like me nā mea hoʻohui kemika, he mea nui nā mea kaiapuni.Loaʻa ka HEC mai ka cellulose a ʻoi aku ka biodegradable ma mua o kekahi mau mānoanoa synthetic.Eia nō naʻe, he mea nui e noʻonoʻo i ka hopena o ke kaiapuni holoʻokoʻa o kāna hana a hoʻohana ʻia i nā noi like ʻole.
i ka hopena
I ka hōʻuluʻulu manaʻo, kū ka hydroxyethylcellulose (HEC) ma ke ʻano he mānoanoa maikaʻi a maʻalahi me nā noi ma nā ʻoihana he nui.ʻO kāna mau waiwai kūʻokoʻa, me ka hoʻoheheʻe wai, ka ʻano rheological a me ka paʻa pH, e lilo ia i mea waiwai nui i nā ʻano huahana like ʻole.Ke hoʻomau nei nā ʻoihana i ka ʻimi ʻana i nā mea ʻē aʻe e pili ana i ke kaiapuni, ʻo nā waiwai biodegradable o HEC i loaʻa mai ka cellulose mea kanu he koho hoʻomau no nā ʻano noi.ʻO ka hoʻomau ʻana i ka noiʻi a me ka hana hou i nā derivatives cellulose e like me HEC hiki ke alakaʻi i nā holomua hou, hāʻawi i ka hana kiʻekiʻe a me ka hōʻemi ʻana i ka hopena o ke kaiapuni.
