Hoʻomaʻemaʻe ʻoihanama ke ʻano maoli he moʻolelo o kekahi mau makahiki wale nō, akā naʻe, ua lawe mai kona puka ʻana mai i nā pono waiwai a me nā pono pilikanaka nui i ka hana ʻoihana. Me ka holomua wikiwiki o nā ʻenehana hoʻomaʻemaʻe, ua hoʻopili ʻia ka hoʻomaʻemaʻe ʻoihana ma aneane nā ʻāpana ʻoihana āpau, me ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka lole, nā petrochemicals, nā mīkini, ka mining a me ka hoʻoheheʻe ʻana, ka mālama ʻana i ka ʻili, ka ʻenekinia kemika, nā mea hana a me nā mika, nā mea uila, nā semiconductors, nā uaki a me nā mea hoʻonani, biology, a me nā optics. Hōʻike piha kēia i ka hiki ke mākeke nui a me ka ikaika o ka hoʻomohala ʻana o ka hoʻomaʻemaʻe ʻoihana.
Ma ke ʻano laulā, ua hoʻokaʻawale ʻia nā mea hoʻomaʻemaʻe ʻoihana i ka hoʻomaʻemaʻe kemika, ka hoʻomaʻemaʻe kino a me ka hoʻomaʻemaʻe microbial e pili ana i kā lākou mau loina hana. ʻO ka hoʻomaʻemaʻe kemika ka mea e haʻaheo nei i ka mōʻaukala hoʻomohala lōʻihi loa, ka laulā ākea o nā noi a me nā ʻano huahana like ʻole. I kēia manawa, ua māhele ʻia nā mea hoʻomaʻemaʻe kemika i ʻekolu mau māhele e like me ko lākou wai: nā mea hoʻomaʻemaʻe solvent organik, nā mea hoʻomaʻemaʻe wai a me nā mea hoʻomaʻemaʻe hapa-wai.
Hoʻākāka kēia ʻatikala i ka haku mele ʻana, ka hana hoʻomaʻemaʻe a me nā ʻano hoʻomohala e hiki mai ana o kēia mau ʻano mea hoʻomaʻemaʻe kemika ʻekolu.
1. Nā Mea Hoʻomaʻemaʻe Hoʻoheheʻe Organic
ʻO nā mea hoʻomaʻemaʻe solvent organik e pili nui ana i nā solvent organik ʻaʻohe wai i loko o kā lākou mau ʻano. ʻO ka hapa nui o lākou e lawe i nā hydrocarbons (alkanes, aromatic hydrocarbons), chlorinated hydrocarbons, fluorinated hydrocarbons, alcohols, alcohol ethers a me nā mea ʻē aʻe ma ke ʻano he mau mea maka nui. ʻO ke ʻano hana o ka hoʻomaʻemaʻe solvent organik, ʻo ia ka hoʻoheheʻe pololei ʻana i nā mea i hoʻoheheʻe ʻole ʻia i ka wai akā hoʻoheheʻe ʻia i nā solvent organik, e like me ka grease, wax, resin, rubber, dyes, kekahi mau mea hoʻopili a me nā mea haumia organik ʻē aʻe.
Loaʻa i nā mea hoʻomaʻemaʻe solvent organik ke ʻano wai ma ka mahana maʻamau a me ke kaomi lewa, ka wai maikaʻi a me ka mānoanoa haʻahaʻa. He leʻaleʻa loa lākou, e waiho ana i kahi koena liʻiliʻi a ʻaʻohe koena ma luna o ka ʻili o nā mea ma hope o ka hoʻomaʻemaʻe ʻana, a ʻaʻole e pala a hōʻino paha i nā mea kumu i ka wā o ke kaʻina hana hoʻomaʻemaʻe.
Eia nō naʻe, ʻo ke kiʻekiʻe o ka volatility o nā mea hoʻoheheʻe organik, me nā kiko paila haʻahaʻa, e hoʻolilo iā lākou i mea maʻalahi e pakele i ke kaiapuni. Ma waena o kēia mau mea, ʻo nā hydrocarbons chlorinated, nā hydrocarbons fluorinated a me nā hydrocarbons halogenated ʻē aʻe he mea ʻawahia i ke kino kanaka. He lipophilic nā waiʻona a me nā ethers waiʻona, hiki ke hōʻeha nui i nā kānaka, nā holoholona a me ke kaiapuni kaiaola.
Eia kekahi laʻana, ʻo kekahi mau mea hoʻomaʻemaʻe solvent organik i pāpā ʻia, e like me trichlorotrifluoroethane, carbon tetrachloride, trichloroethane a me perbromoalkanes, hāʻawi i ka hana hoʻomaʻemaʻe maikaʻi loa a lawe mai i nā pono waiwai. Eia nō naʻe, hoʻopau kēia mau mea i ka papa ozone a hoʻoweliweli i ka Honua. Eia kekahi, he mea paʻakikī loa ka hana hou ʻana a me ka hōʻiliʻili ʻana i kā lākou mau ʻāpana i koe, no laila ua pāpā ʻia kā lākou hoʻohana ʻana.
Ua hoʻohana nui nā mea hoʻomaʻemaʻe wai mua i nā alkalis inorganic alkaline kiʻekiʻe a i ʻole nā paʻakai inorganic. ʻO kā lākou mau ʻano maʻalahi a me ka alkalinity ikaika i lawe mai i nā hemahema he nui i ka wā hoʻomaʻemaʻe a ua hoʻopilikia nui i ka hana hoʻomaʻemaʻe. Ua lanakila nā mea hoʻomaʻemaʻe wai hou i kēia mau hemahema. Hoʻohui lākou i nā surfactants, nā mea hoʻohuihui, nā mea pale i ka palaho, nā mea hoʻopaʻa, nā mea hoʻoheheʻe a me nā mea hana ʻē aʻe, me nā ʻano hana i hoʻopilikino ʻia i hoʻomohala pono ʻia e like me nā kumu hoʻomaʻemaʻe like ʻole a me nā mea kumu.
No ka laʻana, ʻo ka hoʻohemo ʻana i ka momona ma mua o ka electroplating e hoʻohana ana i nā mea i hui pū ʻia e like me ka polyether, triethanolamine oleate a me ka sodium fatty alcohol polyoxyethylene ether sulfate. ʻO kēia ʻano hana i hui pū ʻia, ʻaʻole ia e hōʻino i nā mea kumu. ʻAʻole pono ia i ka hoʻomehana ʻana i ka wā e hoʻohana ai, hana i ka huʻa haʻahaʻa, hāʻawi i nā hopena hoʻomaʻemaʻe maikaʻi loa, hōʻike i ka nui haʻahaʻa a me ke kumukūʻai, a maʻalahi hoʻi e hana. ʻAʻohe mea ʻawahia a pili i ke kaiapuni, kūpono no ka hoʻomaʻemaʻe lima a me ka mīkini me ka mālama maʻalahi ma hope o ka hoʻomaʻemaʻe ʻana.
ʻO ka hoʻonui ʻana i ke ʻano o nā mea hoʻomaʻemaʻe wai e hiki ai ke hoʻokō i nā hana he nui i ka manawa like. I ka hoʻomaʻemaʻe ʻana i nā ʻāpana keleawe, hiki ke hoʻohui ʻia nā mea hoʻopili i ke ʻano hoʻomaʻemaʻe e hoʻopau i ka hoʻomaʻemaʻe a me ka hoʻopili ʻana i hoʻokahi kaʻina hana. ʻO kahi ʻano maʻamau he ʻaila niu momona diethanolamide, glycerin a me ka dodecylbenzenesulfonic acid, me nā mea pale corrosion a me nā mea hoʻomālamalama. Mālama ia i ka mana degresing ikaika a hoʻoponopono pono i ka waiwai pH e pale aku i nā ʻāpana keleawe mai ka pala i hoʻokumu ʻia e ka pH haʻahaʻa loa. ʻO nā mea pale corrosion a me nā mea hoʻomālamalama i hoʻohui ʻia e hāʻawi i nā ʻāpana keleawe i hoʻomaʻemaʻe ʻia me ka luster maikaʻi. Inā hoʻohui ʻia nā mea pale kiʻiʻoniʻoni i loko o ke ʻano, e hana ʻia kahi kiʻiʻoniʻoni pale ma luna o ka ʻili o nā ʻāpana keleawe, e mālama ana iā lākou i ka mālamalama no ka manawa lōʻihi ma hope o ka hoʻomaʻemaʻe ʻana.
No ka hoʻomaʻemaʻe ʻana i ke kaiapuni, ua hoʻomohala hou ʻia nā mea hoʻomaʻemaʻe wai me nā mea hoʻomaʻemaʻe biodegradable a me nā mea ʻawaʻawa ʻole e like me alkyl glycosides a me sophorolipids. ʻO kahi ʻano maʻamau e lawe i nā alkyl glycosides a me sophorolipids e like me nā surfactants, nitrilotriacetic acid ma ke ʻano he mea hoʻohuihui, sodium alginate ma ke ʻano he mea hoʻomānoanoa, a me sodium gluconate ma ke ʻano he mea kōkua. Loaʻa i kēia mau mea āpau ka biocompatibility maikaʻi, ka nui o ka hoʻohaʻahaʻa microbial a me ka liʻiliʻi o ka huhū o ka ʻili. Eia kekahi, ʻaʻohe phosphorus i loko o nā mea kōkua, e hoʻolilo ana i nā huahana i mea aloha kaiapuni. Hoʻohana nui ʻia kēlā mau mea hoʻomaʻemaʻe ma ke ʻano he mea hoʻomaʻemaʻe ʻōmaʻomaʻo no nā lumi kuke, nā lumi ʻauʻau a me nā wahi noho ʻē aʻe, me nā manaʻolana noi ākea.
Hoʻopiha nā mea hoʻomaʻemaʻe wai i nā hemahema o nā mea hoʻomaʻemaʻe solvent organik. He haʻahaʻa ke kumukūʻai, palekana a pili i ke kaiapuni, me nā mea maka maʻalahi ke loaʻa a hiki ke hoʻohou hou ʻia. No laila, hiki i nā mea hoʻomaʻemaʻe wai ke lawelawe ma ke ʻano he pani kūpono no nā mea hoʻomaʻemaʻe solvent organik me ka hoʻokō ʻana i nā hopena hoʻomaʻemaʻe like.
3.Mea hoʻomaʻemaʻe wai hapa-wai
ʻOkoʻa nā mea hoʻomaʻemaʻe semi-aqueous mai nā mea hoʻomaʻemaʻe i hoʻokumu ʻia i ka solvent organik ma ka hoʻohui ʻia ʻana o ka wai a me nā surfactants i nā solvent organik. No kēia kumu, ua kapa ʻia lākou he mau mea hoʻomaʻemaʻe emulsion a i ʻole nā mea hoʻomaʻemaʻe microemulsion i kekahi mau palapala.
Hoʻohui kā lākou ʻano hana hoʻomaʻemaʻe i nā ʻano hana o nā mea hoʻomaʻemaʻe wai e loaʻa ana nā surfactants a me nā mea hoʻomaʻemaʻe solvent. Mālama nā mea hoʻomaʻemaʻe semi-aqueous i nā pono o nā mea hoʻomaʻemaʻe solvent kuʻuna, ʻo ia hoʻi ka detergent ikaika e kūʻē i nā ʻōpala aila a me ka hana hoʻomaʻū maikaʻi loa a me ka komo ʻana ma nā substrates. I kēia manawa, hāʻawi lākou i ka hiki ke wehe i nā mea haumia wai. Ke hoʻohālikelike ʻia me nā mea hoʻomaʻemaʻe solvent organik, hōʻike pū lākou i ka hana hoʻomaʻemaʻe i hoʻomaikaʻi ʻia ma nā mea haumia inorganic. ʻO ka hoʻohui ʻana o ka wai e hoʻokiʻekiʻe i ka flash point a hoʻohaʻahaʻa i ka volatility o nā mea hoʻomaʻemaʻe, kahi e hoʻomaikaʻi ai i ka palekana o nā solvents mua a hoʻonui i kā lākou laulā o ka noi.
Ma muli o ka hiki ke hoʻoheheʻe ʻia o nā mea hoʻoheheʻe organik i ka wai, ua hoʻokaʻawale pinepine ʻia nā mea hoʻomaʻemaʻe semi-aqueous i ke ʻano solvent wai-soluble a me ke ʻano solvent wai-insoluble. ʻO nā mea hoʻoheheʻe wai-soluble he mau alcohols, ethers a me ketones. Hana maikaʻi lākou ma nā mea haumia ʻaila a me ka wai, akā he lapalapa lākou. ʻO ka hoʻohui ʻana iā lākou i loko o nā mea hoʻomaʻemaʻe semi-aqueous me kahi wai liʻiliʻi hiki ke hōʻemi i ka lapalapa no ka hoʻohana palekana. ʻO nā mea hoʻoheheʻe wai-insoluble e komo pū me nā mea hoʻoheheʻe hydrocarbon petroleum-based, terpene hydrocarbon solvents a me nā halogenated hydrocarbons. Loaʻa iā lākou nā kiko uila haʻahaʻa a he lapalapa nui a pahū. Ke hana ʻia kēlā mau mea hoʻoheheʻe organik i nā mea hoʻomaʻemaʻe semi-aqueous, ʻo ka ʻokoʻa nui o ka ʻili ma waena o nā mea hoʻoheheʻe organik non-aqueous a me ka wai e alakaʻi ai i ka incompatibility a me ka stratification inā hoʻohui wale ʻia ka wai. No laila, pono e hoʻokomo ʻia nā surfactants e hōʻemi i ka ʻili interfacial ma waena o nā pae ʻelua, hoʻomaikaʻi i ka hoʻohālikelike a hoʻokō i ka hui like ʻana.
