Ke alakaʻi hoʻomaʻamaʻa i nā Anionic Surfactants: Mai ke kumu a i ke koho

Nā mea hoʻokuʻu ʻaonionihōʻike i ka papa nui loa a hoʻohana nui ʻia o nā mea hana i luna. Loaʻa iā lākou ma nā wahi a pau-mai nā mea holoi holoi lole i kēlā me kēia lā a hiki i nā hana hoʻomaʻemaʻe ʻoihana, nā mea hoʻohui pesticide, a me nā mea hoʻohui paʻa. Hoʻokaʻawale kēia alakaʻi kūpono i nā ʻano nui, hōʻike i nā ʻāpana hana koʻikoʻi, a hāʻawi i nā pae koho i hiki ke hana ʻia no nā mea hoʻokumu a me nā ʻoihana kūʻai.

1. ʻEhā mau ʻano kumu a me nā huahana ʻelele

Hoʻokaʻawale ʻia nā mea surfactant Anionic e kā lākou hui poʻo hydrophilic i ʻehā mau ʻāpana nui. Hoʻoholo ko lākou ʻokoʻa hana i nā noi kūpono:

• Sulfonates: Loaʻa nā huahana ʻelele i ka Linear Alkylbenzene Sulfonate (LAS) a me Alpha-Olefin Sulfonate (AOS). Hōʻike kēia mau mea i ke kūpaʻa maikaʻi o ka waikawa/alkali a me ke kūpaʻa hydrolytic, e hoʻolilo iā lākou i mau mea hana o ka hale a me nā mea holoi ʻoihana. Makemake nui ʻia ʻo AOS i ka wai paʻa a me nā ʻōnaehana acidic, e hāʻawi ana i ka huʻa maikaʻi a paʻa.

• Sulfates/Ester Sulfates: ʻO nā laʻana nui ʻo Sodium Lauryl Sulfate (SDS/K12) a me Sodium Laureth Sulfate (AES). Hāʻawi lākou i ka huʻi a me ka detergency maikaʻi loa akā ua maʻalahi i ka ester bond hydrolysis ma lalo o ka waikawa ikaika a i ʻole nā ​​kūlana wela kiʻekiʻe, no laila kūpono loa ia no ka neʻe ʻana i nā wahi alkaline.

• Carboxylates: Kopa (e.g., sodium stearate) aia maanei. He ʻoluʻolu lākou i ka ʻili akā ʻaʻole hiki ke hoʻomanawanui i ka wai paʻakikī, e hana ana i ka scum insoluble me nā ion calcium a me ka magnesium. ʻO Lamepon A (oleoyl polypeptide) kahi carboxylate kūikawā me ka pilina maikaʻi no nā fiber protein (hulu, silika) a me ka ʻoluʻolu.

• ʻO Phosphate Esters: Hoʻohui kēia i nā ʻano anionic a me nā ʻano nonionic, e hāʻawi ana i ka emulsification maikaʻi a me nā waiwai antistatic. Hoʻohana pinepine ʻia lākou i nā mea kōkua textile a me nā wai hana metala.

2. Nā Kūlana Koʻikoʻi a me nā alakaʻi koho

2.1 Ka hoʻomanawanui ʻana i ka wai paʻakikī a me ka pale ʻana i ka electrolyte

Inā hoʻohana kāu mea hoʻohua i ka wai paʻakikī a i ʻole e koi ana i ka paʻakai kiʻekiʻe (e laʻa, no ka mānoanoa), ʻoi aku ka ʻoi aku o nā sulfonates (LAS/AOS) ma mua o nā sulfate (K12/AES). ʻAʻole pili ka mea mua i ka calcium a me ka magnesium ions, aʻo ka mea hope e hoʻoheheʻe a nalowale paha i ka pono i ka wai paʻakikī.

2.2 pH a me Hydrolytic Paʻa

• Pūnaehana ʻakika (pH 3–6): Sulfonates (ʻoi aku ka AOS) ʻo ia ke koho mua. Paʻa loa ka paʻa C–S, e hōʻoia ana i ka huʻaʻi lōʻihi a me ka detergency me ka ʻole o ka hōʻino. Hiki ke hoʻopili ʻia ka pilina o ka sulfate ester o K12 i ka waika hydrolysis, e alakaʻi ana i ka nalowale ʻana o ka maʻiʻo ikaika i ka manawa.

• Pūnaehana alkaline (pH 8–10): ʻO K12 a me LAS ke hana paʻa. Hāʻawi ʻo K12 i ka ʻoi aku ka wikiwiki o ka hoʻokumu ʻana i ka huʻahu mua a me ka nui o ka huʻihuʻu momona, makemake paha ia no nā huahana ʻāwīwī.

2.3 Nā ʻano o ka huʻa

No ka hana ʻana i ka huʻa wikiwiki a me ka ʻike "wikiwiki", koho iā K12—e laha koke ia a hana i ka huʻa kiʻekiʻe. ʻOi aku ka lohi ʻana o AOS akā hāʻawi mai i ka huʻa hoʻomau me ke kūpaʻa maikaʻi i ka hoʻoheheʻe ʻana i ka ʻaila. Hiki ke hui pū ʻia nā mea ʻelua e kaulike i kēia mau ʻano.

2.4 Palekana Kaiapuni a me Biodegradability

ʻAʻole maikaʻi ka biodegradability a me ka ʻawaʻawa ʻawaʻawa o ka LAS i hoʻokumu ʻia i ka ʻaila. Ke neʻe nei ka ʻoihana i nā mea ʻē aʻe bio-based a i ʻole biodegradable.

• MES (Methyl Ester Sulfonate) mai loko mai o ka pāma a i ʻole ka aila kulina: ʻoi aku ka hoʻohaʻahaʻa mua ʻana ma mua o 80% i loko o 8 mau lā a loaʻa ka mineralization piha i loko o 3 lā—ʻoi aku ka maikaʻi ma mua o LAS.

• ʻO nā surfactants i hoʻokumu ʻia i ka amino-acid (e laʻa., sodium cocoyl glycinate): loaʻa mai nā ʻakika amino maoli, hōʻike lākou i ka biodegradability maikaʻi loa, haʻahaʻa haʻahaʻa i ka ʻili, a hoʻohana nui ʻia i nā mea hoʻomaʻemaʻe maka.

3. ʻOihana a me nā noi kūikawā

1. Hoʻoponopono i ka wai o ka honua a me ka lepo: ʻO nā surfactants nonionic maʻamau e hoʻoulu pinepine i ka emulsion blocking a me ka pore clogging. Anionic Gemini surfactants (e.g., sulfonate/sugar-based blends) he haʻahaʻa adsorption, haʻahaʻa CMC, a me ka non-emulsifying ʻano, e loaʻa ana ka hoʻoneʻe ʻana ma luna o 99%.

2. Kāohi ʻino: Hiki i nā surfactants anionic i hoʻomaʻemaʻe ʻia (e laʻa, ka ʻaila-corn MES) ke hana i kahi kiʻiʻoniʻoni pale paʻa ma luna o nā ʻili metala, e kāohi ana i ka ʻino ma nā wahi paʻakai me ka maikaʻi ma mua o 98%.

3. Hana ʻia a me ka Paʻa: ʻO nā alkyl ether sulfate kūikawā (e laʻa, isotridecyl ether sulfate) e lawelawe ma ke ʻano he mau mea hoʻokomo ea, e hoʻomaikaʻi nui ana i ke kūpaʻa manuahi-thaw i loko o ka ʻeke.

4. Nā ʻōlelo aʻo kūpono

Mai hui punā mea hoʻokuʻu anionicpololei me nā cationic surfactants (e.g., quaternary ammonium bactericides a i ʻole cationic fabric softeners)—e alakaʻi ana kēia i ka ua hiki ʻole ke hoʻoheheʻe ʻia a me ka hoʻopau ʻana i nā ʻāpana ʻelua. Inā pono ka noho pū ʻana, e hoʻohana i ka hoʻohui sequential a i ʻole nā ​​ʻenehana hoʻohui kūikawā. Hoʻohui maikaʻi nā mea surfactants anionic me nā surfactants amphoteric a me nā nononionic, e hāʻawi pinepine ana i nā hopena synergistic.

Hoʻopau hope: Ke koho ʻana i kahi surfactant anionic, e hoʻoholo mua inā e hāʻule ka hana ma lalo o sulfonate a sulfate ma ka loiloi ʻana i ka pH ʻōnaehana a me ka paʻakikī o ka wai. A laila e hoʻomaʻemaʻe i ke koho e pili ana i ka ʻaoʻao foam, ka ʻili o ka ʻili, a me nā koi kūlohelohe. No ka hoʻohana ʻana i nā ʻoihana, e loiloi hou i ka hana adsorption, hiki ke ʻino, a me ka hoʻomanawanui paʻakai. Mālama kēia ʻano pae i ka pono ʻenehana a me ka maikaʻi o ke kumukūʻai.
