Ka Loiloi Paʻa o HEC i nā ʻAno Wai Holoi Kīʻaha

ʻO ka Hydroxyethyl cellulose (HEC)he hui polymer non-ionic, wai-soluble i loaʻa ma o ka hoʻololi kemika o ka cellulose kūlohelohe. Ma muli o kona mau waiwai hoʻomānoanoa maikaʻi loa, emulsifying, suspending, stabilizing, a me ka hoʻohālikelike, hoʻohana nui ʻia ʻo HEC i ka ʻoihana kemika o kēlā me kēia lā, ʻoi aku hoʻi i nā huahana hoʻomaʻemaʻe wai e like me nā wai holoi kīʻaha, nā kopa lima, a me nā shampoos.

1. Ke Kūlana Hana o HEC i nā Wai Holoi Kīʻaha

I loko o nā ʻano wai holoi kīʻaha, ʻo nā hana nui o HEC penei:
Ka Mānoanoa a me ka Hoʻoponopono ʻana: Hoʻonui maikaʻi ʻo HEC i ka mānoanoa o ka ʻōnaehana wai holoi kīʻaha, e hāʻawi ana i ka huahana i kahi hiʻohiʻona maikaʻi, ka maʻalahi o ke kahe ʻana, a me ka ʻike mea hoʻohana.

Ka Hoʻopaʻa ʻana i ka Hoʻokuʻu ʻana: I loko o nā wai holoi kīʻaha e loaʻa ana nā mea hoʻohui particulate (e like me nā ʻāpana exfoliating a me ka pauka momi), hiki iā HEC ke pale i ka sedimentation particle a mālama i ka homogeneity formulation.

Ka Paʻa ʻana o ka Huʻa: Hiki i ka HEC ke hana pū me nā surfactants e hoʻomaikaʻi i ka maikaʻi a me ke kūpaʻa o ka huʻa.

Hoʻoponopono Hoʻohālikelike: Ma ke ʻano he polymer nonionic, kūpono loa ʻo HEC me nā surfactants anionic, cationic, a me nonionic, e pale ana i ka stratification formulation.

2. ʻAno Hana Paʻa HEC

2.1. Paʻa Wela

Hōʻike ʻo HEC i ke kūpaʻa wela kiʻekiʻe loa i hoʻohālikelike ʻia me ka hapa nui o nā polymers kūlohelohe. I nā ʻōnaehana kemika o kēlā me kēia lā ma 25-50°C, mālama ʻo HEC i ka ʻōnaehana molekala paʻa a ʻaʻole maʻalahi e hoʻohaumia ʻia.

ʻOiai i loko o ka hana ʻana i ka mahana kiʻekiʻe (e like me ke kahua hoʻoheheʻe a me ka hoʻomehana ʻana) a i ʻole nā ​​wahi mālama lōʻihi, mālama nā ʻōnaehana HEC-thickened i ka viscosity maikaʻi me ka ʻole o ka lahilahi nui. He mea nui loa kēia ʻano no ke kūʻai paʻa ʻana o nā detergents i ka wā o ka halihali wela kiʻekiʻe a i ʻole ma nā mākeke hema.

2.2. Paʻa Ionic

Loaʻa pinepine i nā wai holoi kīʻaha nā paʻakai inorganic like ʻole (e like me ka sodium chloride a me ka sodium sulfate) a me nā ʻāpana electrolyte. Hoʻonāwaliwali pinepine kēia mau ions i ka hopena o nā mea hoʻomānoanoa maʻamau. Eia nō naʻe, ma ke ʻano he polymer nonionic, ʻaneʻane ʻaʻole i hoʻopilikia ʻia ka hana hoʻomānoanoa HEC e nā loli i ka nui o ka electrolyte.

I nā ʻōnaehana paʻakai kiʻekiʻe, mālama mau ʻo HEC i ka mānoanoa paʻa a me ka transparency, e pale ana i ka hoʻokahe ʻana o ka paʻakai a me ka stratification i loko o nā detergents i ka wā e mālama ai.

2.3. Paʻa pH

ʻO ka pH o nā wai holoi kīʻaha ma waena o 6.5 a me 8.5. Hōʻike ʻo HEC i ke kūpaʻa kemika maikaʻi loa i loko o kēia pae, me ka ʻole o ka hōʻino ʻia a i ʻole ka inactivation. ʻOiai i ke alo o nā mea alkaline iki a acidic paha i loko o ka hoʻohuihui ʻana, mālama nā kaulahao molekala HEC i ka hydration ikaika, e mālama ana i ka homogeneity o ka ʻōnaehana.

Eia kekahi, ʻo ke ʻano nonionic o HEC e pale aku i ka hoʻopilikia ʻana o ka uku i hoʻokumu ʻia e nā loli o ka pH, e hōʻoiaʻiʻo ana e noho maopopo ka wai holoi kīʻaha no ka wā lōʻihi.

2.4. Paʻa Hoʻohālikelike

Hōʻike ʻo HEC i ka launa maikaʻi loa me nā surfactants like ʻole (e like me AES, LAS, APG, a me nā mea ʻē aʻe) me ka ʻole o ka hoʻoulu ʻana i ka flocculation a i ʻole stratification. Hiki i kona mau kaulahao molekala ke hana i nā pilina nāwaliwali me nā surfactants i loko o ka hopena, no laila e hoʻomaikaʻi ana i ka viscoelasticity a me ke kūpaʻa o ka huʻa o ka ʻōnaehana.

I loko o nā ʻōnaehana paʻakikī e loaʻa ana nā ʻala hui, nā pigments, a me nā mea mālama, mālama ʻo HEC i ka hoʻokahe maikaʻi ʻana, e pale ana i ka hoʻokaʻawale ʻana o ka pae a i ʻole ka ua i ka wā mālama lōʻihi.

3. Nā Kumu Koʻikoʻi e Hoʻopilikia ana i ke Paʻa o HEC

3.1. Kekelē o ka Hoʻololi (DS) a me ka Papa Viscosity:

Hāʻawi nā HEC pani kiʻekiʻe-kekelē i ka solubility maikaʻi a me ka hoʻomanawanui paʻakai, e kūpono ai lākou no nā ʻano detergent moakaka; ʻoi aku ka ikaika o nā huahana pani haʻahaʻa i ka hiki ke mānoanoa akā haʻahaʻa iki ka paʻa. Ma keʻano laulā, koho ʻia nā HEC me ka viscosity waena a kiʻekiʻe (25000–60000 mPa·s) e kaulike maikaʻi i ka mānoanoa a me ka moakaka.

3.2. Kaʻina Hoʻopau:

Pono e hoʻopuehu like ʻia ka HEC i loko o ka wai anuanu, a laila e hoʻomehana mālie ʻia e hoʻoheheʻe loa, e pale ana i ka hui ʻana. Hiki i ka hoʻoheheʻe piha ʻole ke alakaʻi maʻalahi i nā mea particulate a i ʻole ka turbidity i loko o ka ʻōnaehana, a laila e hoʻopilikia ai i ke kūpaʻa o ka hoʻohuihui ʻana.

3.3. Ka Hoʻohuihui ʻana o ka Electrolyte:

ʻOiai he maikaʻi ka hoʻomanawanui paʻakai o ka HEC, hiki nō ke emi iki ka mānoanoa ke kiʻekiʻe loa ka nui o ka electrolyte i loko o ka ʻōnaehana (>6% NaCl). No laila, i nā ʻano paʻakai kiʻekiʻe, pono e hoʻonui kūpono ʻia ka nui o ka HEC i hoʻohui ʻia, a i ʻole e koho ʻia kahi ʻano HEC i hoʻololi ʻia.

3.4. ʻAno Surfactant:

ʻOkoʻa iki ka kūlike o HEC me nā ʻōnaehana surfactant like ʻole. No ka laʻana, hōʻike ʻo HEC i ke kūpaʻa huʻa kiʻekiʻe ma nā ʻōnaehana LAS a me AES; ʻoiai i loko o nā wai holoi kīʻaha aloha kaiapuni e loaʻa ana iā APG, ʻoi aku ka ʻike ʻia o nā hopena hoʻomānoanoa a me ka hoʻokuʻu ʻana o HEC.

4. Nā Pōmaikaʻi o HEC i nā Wai Holoi Kīʻaha

ʻIke Māmā o ka ʻŌnaehana: He moakāka a moakāka ka wai hoʻoheheʻe ʻia, ʻaʻole ia e hoʻopilikia i ke ʻano o ka wai holoi kīʻaha.

Maikaʻi ka palaho ʻana: Loaʻa mai ka cellulose kūlohelohe, kūlike ia me ke ʻano o nā huahana kemika o kēlā me kēia lā e pili ana i ke kaiapuni.

ʻUʻuku ka hoʻonāukiuki: ʻAʻole ia e hoʻoulu i nā maʻi ʻili a kūpono no nā ʻano wai holoi kīʻaha akahai.

Hoʻohālikelike ākea: Pili i nā ʻano ʻōnaehana wai holoi kīʻaha like ʻole, e like me nā wai holoi kīʻaha kūlike ʻole, nā ʻano hoʻohuihui i hoʻohuihui ʻia, a me nā ʻano hoʻohuihui huʻa kiʻekiʻe a haʻahaʻa paha.

HECʻaʻole wale ia he mea hoʻomānoanoa maikaʻi loa i nā ʻano wai holoi kīʻaha akā he mea hoʻopaʻa ʻōnaehana koʻikoʻi hoʻi. ʻO kona kūpaʻa wela maikaʻi loa, kūpaʻa ionic, kūpaʻa pH, a me ka hoʻohālikelike e hōʻoia i ka mālama ʻana o nā wai holoi kīʻaha i ke ʻano maikaʻi a me ka hana i ka wā e mālama ai, lawe ʻia, a hoʻohana ʻia. Ma ke koho pono ʻana i nā ʻano HEC a me nā kaʻina hana hoʻohui, hiki ke hoʻomaikaʻi nui ʻia ka maikaʻi holoʻokoʻa a me ka hoʻokūkū mākeke o nā wai holoi kīʻaha. I ka wā e hiki mai ana, me ka hoʻomohala ʻana o ka palekana kaiapuni ʻōmaʻomaʻo a me ka kemika hoʻomau, e hōʻike ʻo HEC i nā manaʻolana noi ākea i nā huahana detergent kiʻekiʻe.
