ʻO kā mākou huahana nui: Amino silicone, block silicone, hydrophilic silicone, kā lākou silicone emulsion a pau, hoʻomaʻemaʻe wikiwiki i ka hoʻomaʻemaʻe ʻana, wai repellent (Fluorine free, Carbon 6, Carbon 8), nā mea holoi holoi demin (ABS, Enzyme, Spandex protector, Manganese remover), ʻāina hoʻoili nui: India, Pakistan, Bangladesh, Türzkiye

 

ʻO ka hopena holoi o nā surfactants ka ʻano kumu e hāʻawi ai i nā surfactants i ka hoʻohana pono loa. Hoʻopili ia i ke ola o kēlā me kēia lā o nā tausani o nā hale. A ua hoʻohana nui ʻia i nā ʻoihana like ʻole a me ka hana ʻoihana.

ʻO ka hoʻomaʻemaʻe maloʻo kahi ʻano o ka holoi ʻana i nā solvents organik, e hoʻohana ana i ka solubility o nā solvents a me ka solubility o nā surfactants e wehe i ka lepo mai ka ʻili o nā lole. ʻO kona pōmaikaʻi ʻo ia ka mea hiki ke pale i ka hiki ʻole ke hoʻihoʻi ʻia o ka hulu hipa a me nā lole silika i hana ʻia e ka holoi ʻana, a me ka deformation a me ka manaʻo maikaʻi ʻole o ka lole.

 

Hiki ke hoʻokaʻawale ʻia ka lepo ma luna o nā lole i ʻekolu mau ʻano: hiki ke hoʻoheheʻe ʻia ka ʻaila, hiki ke hoʻoheheʻe ʻia i ka wai, a me ka ʻaila a me ka wai ʻole.

Hiki ke hoʻoneʻe pololei ʻia ka lepo hiki ke hoʻoheheʻe ʻia me nā mea hoʻoheheʻe organik. ʻO nā mea hoʻonā hiki ke hoʻohana ʻia no ka holoi ʻana, ʻo ia ka nui o ka petroleum hydrocarbons māmā, ka nui o nā aliphatic hydrocarbons e like me 1,3-diethylcyclohexane, cycloaliphatic hydrocarbons, a me 1,2,4-trimethylphenylaromatic hydrocarbons. Eia kekahi, aia kekahi carbon tetrachloride, trichlorethylene, tetrachloroethylene, etc.

I mea e wehe ai i ka lepo me ka hoʻoheheʻe wai maikaʻi a i ʻole hydrophilicity ikaika, pono e hoʻohui ʻia kahi wai liʻiliʻi a me nā surfactants i ka ʻōnaehana. Hiki i ka hoʻohui ʻana o nā surfactants ke pale i ka waiho hou ʻana o ka lepo paʻa i loko o ka solvent. ʻAʻole hilinaʻi hou ka paʻa ʻana o ka dispersion a me ka hoʻokuʻu ʻana o ka lepo i loko o ka pāpaʻi kūlohelohe i ka repulsion electrostatic ma waena o nā ʻāpana, akā hiki ke hoʻoholo ʻia e ka adsorption o nā surfactants ma ke kikowaena paʻa-wai.

Hoʻopili ʻia nā surfactants i loko o ka pāpaʻi organik ma nā ʻili paʻa e like me nā pūʻulu polar, me nā kaulahao lipophilic hydrocarbon i kuhikuhi ʻia i ke kūlana adsorption o nā mea hoʻoheheʻe organik a hoʻopili ʻia ma ka interface paʻa-wai. Hiki i kēia ke hana i kahi kiʻiʻoniʻoni hoʻonā o nā kaulahao hydrogen carbon ma ka ʻili o ka lepo paʻa, e hana ana i kahi pale ikehu no ke keakea spatial a pale i ka hōʻiliʻili a waiho hou ʻana i ka lepo ma ka ʻili lole. ʻO ka hiki ʻana mai o kahi wai liʻiliʻi e hiki ke hoʻoheheʻe i nā ʻāpana a me nā ʻili textile, e maʻalahi iā lākou ke launa pū me nā pūʻulu polar o nā surfactants, he mea pono ia no ka adsorption o nā surfactant ma nā ʻili paʻa (ʻoi aku ka maʻamau o nā polar surfaces). He mea maikaʻi kēia no ka hoʻomaikaʻi ʻana i ka holoi holoi. Eia kekahi, i ka wā e hana ai nā surfactants i nā micelles hoʻohuli i nā mea hoʻoheheʻe organik, hoʻoheheʻe pinepine ʻia kahi wai liʻiliʻi a me kona lepo e hoʻoheheʻe ʻia i ka wai i nā micelles i ka manawa like.

 

Pono nā surfactants i hoʻohana ʻia no ka hoʻomaʻemaʻe maloʻo i kēia mau kūlana:

① Hiki iā ia ke hoʻoheheʻe i ka holoi holoi ʻana a hana i nā micelles hoʻohuli, a lawa ka hiki ke hoʻohui i ka wai hiki ke hoʻopuehu maikaʻi i ka lepo paʻa a hāʻawi i ke kūpaʻa hoʻomaha maikaʻi i nā mea hoʻoheheʻe organik;
③ Haʻahaʻa koena adsorption ma ka holoi lole a me nā kānana;
④ ʻAʻohe ʻala, ʻaʻohe hopena ʻino i ka holoi lole, ʻaʻohe corrosiveness i nā metala, etc.

Pono e hoʻoheheʻe ʻia nā surfactants i hoʻohana ʻia no ka hoʻomaʻemaʻe maloʻo.

 

ʻO nā mea maʻamau i hoʻohana ʻia:

① Nā mea hoʻoheheʻe anionic e like me ka petroleum sulfonate, sodium alkylbenzenesulfonate (a i ʻole amine paʻakai), a me ka sodium succinate sulfonate;

② ʻAʻole ionic surfactants e like me polyoxyethylene alkyl alcohol ethers, polyoxyethylene alkyl phenols, polyoxyethylene alkyl amides, etc.
