Ma ke ʻano he mea waena organik koʻikoʻi a me ka mea hoʻoheheʻe i hoʻohana nui ʻia i ka ʻoihana kemika, hoʻohana nui ʻia ka cyclohexanone i nā ʻoihana e like me ka resin, ka uhi ʻana a me ka fiber kemika. Ma muli o kona ʻano o ka lapalapa ʻana, ka volatility a me ka huhū, kū pinepine nā nīnau like ʻole i ka wā o kāna hana ʻana, mālama ʻana, lawe ʻana a me ka hoʻohana ʻana. Hoʻokaʻawale kēia pepa i nā nīnau ʻoihana kiʻekiʻe a hāʻawi i nā pane ʻoihana e pili ana i nā waiwai kino a me nā kemika a me nā kikoʻī palekana, e hāʻawi ana i nā kuhikuhi kūpono no nā mea hana pili.
1. Nā Waiwai Kino a me nā Kemika Kumu o Cyclohexanone
ʻO ke ʻano molekala o Cyclohexanone (CAS: 108-94-1) he C₆H₁₀O. Ma lalo o ka mahana maʻamau a me ke kaomi, he wai moakaka ʻole ia a melemele palupalu me kahi ʻala ʻono kūikawā e like me ka mint a me ka camphor, he mea hoʻonāukiuki i nā ʻano kiʻekiʻe. Loaʻa iā ia nā ʻano kino a me nā kemika paʻa: kahi kiko heheʻe o -45°C, kahi kiko paila o 155.6°C, a me ka nui o 0.9478 g/cm³ ma 20°C. ʻOiai he māmā ia ma mua o ka wai, e lana ia ma luna o ka ʻili wai inā he leakage. Hoʻoheheʻe iki ʻia i ka wai, hiki ke hui pū ʻia ka cyclohexanone me ka hapa nui o nā mea hoʻoheheʻe organik e like me ka ethanol, ether a me benzene. Me kahi kiko uila pani o 46°C, ua hoʻokaʻawale ʻia ʻo ia he wai lapalapa Class B. Hiki i kona mahu ke hana i nā hui pahū me ka ea, me ka palena pahū nui o 1.1%–9.4%. He mea maʻalahi ia i ke ahi a me ka pahū ke hōʻike ʻia i nā lapalapa ahi, nā mahana kiʻekiʻe a me nā mea hoʻoheheʻe ikaika.
2. Nā Hoʻohana Koʻikoʻi o Cyclohexanone
ʻO Cyclohexanone kahi mea maka koʻikoʻi i ka ʻenekinia kemika maikaʻi me nā hiʻohiʻona noi ākea. ʻO kāna hoʻohana nui ʻana ka hoʻomākaukau ʻana o ka caprolactam a me ka adipic acid, kahi i hana hou ʻia e hana i ka nylon 6, nylon 66 a me nā huahana fiber kemika ʻē aʻe, e lilo ia i waena koʻikoʻi i ka ʻoihana lole a me ka fiber kemika. I kēia manawa, lawelawe ia ma ke ʻano he mea hoʻoheheʻe ʻoihana hana kiʻekiʻe me ka solubility ikaika no nā mea polymer e like me ka polyurethane, epoxy resin a me ka acrylic resin, a hoʻohana nui ʻia i ka hana ʻana o nā uhi, nā ʻīnika, nā mea hoʻopili a me nā mea hoʻopau ʻili. Eia kekahi, hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana o nā antioxidants rubber, nā mea kōkua synthesis organik a me nā waena lāʻau lapaʻau, a hoʻohana pinepine ʻia i ka hana plastik a me ka hoʻomaʻemaʻe metala.
3. Nā Pōʻino o Cyclohexanone i ke Ola Kino o ke Kanaka
He mea ʻawahia a hoʻonāukiuki ka Cyclohexanone, a hiki ke komo i ke kino o ke kanaka ma o ka hanu ʻana i ka hanu, ka pili ʻana o ka ʻili a me ka ʻai ʻana i ka waha. ʻO ka lōʻihi o ka hoʻopili ʻana i ka cyclohexanone haʻahaʻa e hoʻonāukiuki i nā membrane mucous o nā maka, ka ihu a me ka ʻāʻī, e hana ana i nā hōʻailona e like me ka haehae ʻana, ke kuni ʻana a me ka maloʻo o ka ʻāʻī. ʻO ka lōʻihi o ka pili ʻana o ka ʻili e hōʻino i ka papa ʻaila ʻili, e alakaʻi ana i ka maloʻo, ka ʻili ʻana, ka haki ʻana a me ka dermatitis pili. ʻO ka hanu ʻana i ka mahu nui e kāohi i ka ʻōnaehana nerve waena, e hopena ana i nā hōʻailona anesthetic e like me ka dizziness, nausea, luhi a me ka luaʻi ʻana, a ʻo nā hihia koʻikoʻi e pili ana i ka huikau, ka hypothermia a me ka haʻalulu. ʻO ka ʻai ʻana i ka ulia pōpilikia e hoʻonāukiuki i ka ʻōpū gastrointestinal a hōʻino i nā hana ate a me nā puʻupaʻa. I nā kūlana hana, ua kāohi pono ʻia ka nui o ka ʻae ʻia ma kahi hana ma 200 mg/m³.
4. Nā Kikoʻī Maʻamau no ka Mālama ʻana a me ka Lawe ʻana o Cyclohexanone
No ka mālama ʻana, pono e mālama ʻia ka cyclohexanone i loko o kahi hale kūʻai kemika kūikawā i anuanu, maloʻo a maikaʻi ka ea, kahi mamao aku mai nā kumu ahi a me nā kumu wela. ʻAʻole pono e ʻoi aku ka mahana o ka hale kūʻai ma mua o 30°C, a pāpā ʻia ka lā pololei. Pono e sila paʻa ʻia nā ipu e pale aku i ka volatilization a me ka leakage. Pāpā ʻia ka mālama ʻana i nā mea hoʻohuihui me nā oxidants, nā waikawa ikaika a me nā kumu ikaika. Pono e hoʻolako ʻia ka hale kūʻai me nā kukui pale pahū, nā hale hoʻouluulu a me nā mea kinai ahi. No ka lawe ʻana, pono e hāʻawi ʻia ka cyclohexanone e like me nā kūlana no nā kemika wai ʻā. Pono nā kaʻa lawe e paʻa i nā palapala hōʻoia lawe kemika weliweli kūpono a hoʻolako ʻia me nā mea anti-static, nā lako kinai ahi a me nā lako pale pilikia. I ka wā o ka lawe ʻana, pono e pale ʻia ka ʻike ʻana i ka lā, ka kuʻi nui a me ka hopena. Pāpā ʻia ka lawe ʻana i nā meaʻai a me nā oxidants. Pono e mālama mālie ʻia nā hana hoʻouka a me ka wehe ʻana e pale aku i ka leakage.
5. Ka Lapaʻau Pilikia no ka Leakage Cyclohexanone a me ka Hōʻike ʻana i ke Kanaka
Inā pili ka ʻili, e wehe koke i nā lole haumia a holoi pono i ka ʻili i hoʻopilikia ʻia me ka wai maʻemaʻe e kahe ana no 15 mau minuke ma ka liʻiliʻi. No ka pili ʻana me ka maka, e paʻa i nā lihilihi maka a holoi mau i nā maka me ka wai maʻemaʻe a i ʻole ka saline maʻamau ma mua o ka ʻimi ʻana i ka lāʻau lapaʻau i ka manawa kūpono. Inā hanu ʻia, e neʻe koke mai kahi haumia i ka ea hou. E hāʻawi i ke kōkua oxygen no nā pilikia hanu, a hana koke i ka hanu hana no ka hoʻopaʻa ʻana i ka hanu ma mua o ka mālama ʻana i ka lāʻau lapaʻau. Ke puka mai ka leaka, e hoʻokuke koke i nā limahana pili ʻole, e hoʻokaʻawale i kahi leaka a ʻoki i nā kumu ahi āpau e pale aku i nā lapalapa ākea a me ka uila static. Hiki ke hoʻopili ʻia ka leaka ʻana o kahi liʻiliʻi me ke one a i ʻole ke kalapona i hoʻāla ʻia. No ka leaka nui, e kūkulu i nā ʻauwai no ka hoʻopaʻa ʻana, e hōʻiliʻili i ka wai i leaka no ka hoʻōla ʻana a i ʻole e hāʻawi aku i nā ʻoihana ʻoihana no ka hoʻolei ʻana. Ua pāpā loa ʻia ka hoʻokuʻu pololei ʻana i loko o nā wai a me nā ʻauwai.
6. Nā Mālama no ka Hana Cyclohexanone i kēlā me kēia lā
Pono nā mea hana e loaʻa i ke aʻo ʻoihana a mālama pono i nā kikoʻī hana. Pono e ʻaʻahu ʻia nā lako palekana pilikino e like me nā goggles, nā mīkina lima rapa pale-solvent a me nā pale kinoea i ka wā o ka hana. Pono e mālama i ka ea piha ma kahi hana, a pāpā ʻia ka puhipaka, ka ʻai ʻana a me ka inu ʻana e hoʻopau i nā pilikia ahi. Pono e hana nā lako hana āpau i kahi pani, a e nānā pinepine ʻia nā paipu a me nā valves e pale aku i ka liki ʻana. Ma hope o ka hana, e holoi pono nā mea hana i nā lima a me ka maka a hoʻololi i nā lole hana, a ʻaʻole e ʻaʻahu i nā lole hana haumia ma nā wahi noho. Eia kekahi, e hoʻonohonoho ʻia nā hōʻailona hōʻike ma kahi hana, i lako me nā pono holoi ulia pōpilikia a me nā lako kinai ahi, a e hana ʻia nā hoʻomaʻamaʻa ulia pōpilikia maʻamau.
