Hei takawaenga waro nui me te whakarewa e whakamahia whānuitia ana i roto i te umanga matū, ka whakamahia te cyclohexanone i roto i ngā umanga pēnei i te kapia, te paninga me te muka matū. Nā ōna āhuatanga mura, te hurihanga me te riri, he maha ngā pātai ka ara ake i te wā e hangaia ana, e rongoatia ana, e kawehia ana me te tono. Ka whakarōpūhia e tēnei pepa ngā pātai auau o te umanga, ā, ka whakaratohia he whakautu ngaio i runga i ngā āhuatanga ā-tinana me te matū me ngā whakaritenga haumaru, e tuku ana i ngā tohutoro mahi mō ngā kaimahi e tika ana.
1. Ngā Āhuatanga Ā-tinana me te Matū Taketake o te Cyclohexanone
Ko te tauira ngota o te Cyclohexanone (CAS: 108-94-1) ko te C₆H₁₀O. I raro i te pāmahana me te pēhanga noa, he wai mārama, kāore he tae, he kowhai mā, he kakara reka motuhake rite ki te mīti me te camphor, he mea whakapataritari i ngā kukū tiketike. He pūmau ngā tawhā ā-tinana me te matū matua: he ira rewa o te -45°C, he ira kohua o te 155.6°C, me te mātotoru o te 0.9478 g/cm³ i te 20°C. Nā te mea he mama ake i te wai, ka mānu i runga i te mata o te wai mēnā ka turuturu. He iti te wairewa i roto i te wai, ka taea te whakaranu ki te nuinga o ngā whakarewa waro pēnei i te etanoru, te etera me te benzene. Me te ira mura kapu-kati o te 46°C, ka whakarōpūtia hei wai mura Akomanga B. Ka taea e tōna kohu te hanga ranunga pahū me te hau, me te rohe pahū rōrahi o te 1.1%–9.4%. He ngāwari ki te mura me te pahū ina pāngia e te mura ahi, e ngā pāmahana teitei me ngā waikura kaha.
2. Ngā Whakamahinga Matua o te Cyclohexanone
Ko te Cyclohexanone tētahi rauemi matua o te hangarau matū pai me ngā whakamahinga whānui. Ko tōna whakamahinga matua ko te whakarite i te caprolactam me te waikawa adipic, ka tukatukahia anō hei whakaputa i te nairona 6, te nairona 66 me ētahi atu hua muka matū, ka waiho hei takawaenga matua i roto i te umanga kakahu me te muka matū. I taua wā, he whakarewa ahumahi mahi-teitei me te wairewa kaha mō ngā rauemi polymer tae atu ki te polyurethane, te kapia epoxy me te kapia kiriaku, ā, he whānuitia te whakamahinga i roto i te hanga paninga, waituhi, piripiri me ngā kaihoko whakaoti hiako. Hei tāpiri, ka taea te whakamahi i roto i te whakarite i ngā antioxidants rapa, ngā āwhina hanga rauropi me ngā takawaenga rongoā, ā, he mea noa te whakamahinga i roto i te tukatuka kirihou me te horoi whakarewa.
3. Ngā Tūponotanga o te Cyclohexanone ki te Hauora Tangata
He paitini, he whakapataritari hoki te cyclohexanone, ā, ka taea te uru ki te tinana tangata mā te manawa manawa, te pa ki te kiri me te horomitanga ā-waha. Mā te roa o te wā ka whakapataritarihia ngā kiriuhi mucous o ngā kanohi, ihu me te korokoro e te cyclohexanone iti-kukū, ka puta he tohu pēnei i te haehae, te maremare me te korokoro maroke. Mā te roa o te pa ki te kiri ka kino te paparanga hinu kiri, ka maroke, ka kiri, ka pakaru, ka pā te kiri, ka pā te kiri. Mā te manawa i te kohu nui-kukū ka aukati i te pūnaha io matua, ka puta he tohu rongoā pēnei i te whanoke, te whakapairuaki, te ngenge me te ruaki, ā, i ngā wā kino ka uru pea te pōhēhē, te hypothermia me te wiri. Mēnā ka horomia, ka whakapataritarihia te ara kai, ka kino hoki ngā mahi ate me te whatukuhu. I roto i ngā āhuatanga mahi, ko te kukū mōrahi e whakaaetia ana i te wāhi mahi ka tino whakahaerehia ki te 200 mg/m³.
4. Ngā Whakatakotoranga Paerewa mō te Rokiroki me te Kawe i te Cyclohexanone
Mō te penapena, me pupuri te cyclohexanone i roto i tētahi whare putunga matū motuhake, he matao, he maroke, he pai te hauhautanga, kia matara atu i ngā pūtake ahi me ngā pūtake wera. Kaua te pāmahana o te whare putunga e neke ake i te 30°C, ā, kāore e whakaaetia te rā tika. Me hiri pūmau ngā ipu hei ārai i te mimiti me te turuturu. Kāore e whakaaetia te penapena ranunga me ngā waikura, ngā waikawa kaha me ngā turanga kaha. Me whai rama ātete-pahūtanga, ngā whakaurunga hauhautanga me ngā tinei ahi te whare putunga. Mō te kawe, me tuku te cyclohexanone i runga anō i ngā paerewa mō ngā matū kino wai mura. Me mau ngā waka kawe i ngā tiwhikete kawe matū kino whai tohu, ā, me whai taputapu ārai-pūmau, taputapu tinei ahi me ngā taputapu tiaki ohorere. I te wā e kawe ana, me karo te pānga ki te rā, te tukinga nui me te pānga. Kāore e whakaaetia te kawe ranunga me te kai me ngā waikura. Me ata whakahaere te uta me te tango i ngā mahi hei ārai i te turuturu.
5. Te Maimoatanga Ohotata mō te turuturu o te Cyclohexanone me te pānga ki te tangata
Mēnā ka pā ki te kiri, tangohia tonutia ngā kākahu kua poke, ka horoia rawatia te kiri kua pāngia ki te wai ma e rere ana mō te 15 meneti pea. Mēnā ka pā ki ngā kanohi, pupuritia ngā kamo kia tuwhera, ka horoia tonutia ngā kanohi ki te wai ma, ki te tote noa rānei i mua i te rapu maimoatanga hauora i te wā tika. Mēnā ka manawahia, neke wawe atu i te wāhi kua poke ki te hau hou. Hoatu he āwhina hāora mō ngā uauatanga manawa, ā, mahi tonu i te manawa horihori mō te aukati manawa i mua i te maimoatanga hauora. Kia puta he turuturu, whakawātea wawe i ngā tāngata kāore e tika ana, wehea te wāhi turuturu, ka tapahia ngā pūtake ahi katoa hei ārai i ngā mura tuwhera me te hiko pateko. Ka taea te mimiti i te turuturu o te wāhi iti ki te onepu, ki te waro whakahohe rānei. Mō te turuturu nui, hanga he awa hei pupuri, kohia te wai i turuturu hei whakaora, tukuna rānei ki ngā umanga ngaio hei whakakore. Kāore e whakaaetia te tuku tika ki ngā wai me ngā parakaingaki.
6. Ngā Whakatūpato mō te Mahi Cyclohexanone o ia Rā
Me whiwhi ngā kaiwhakahaere i te whakangungu ngaio, ā, me tino piri ki ngā whakaritenga whakahaere. Me mau ngā taputapu tiaki whaiaro tae atu ki ngā mōhiti kanohi, ngā karapu rapa ātete-whakarewa me ngā kopare hau i te roanga o te mahi. Me mau tonu te hauhautanga o te wāhi mahi, ā, me rāhui te momi hikareti, te kai me te inu hei whakakore i ngā tūponotanga ahi. Me mahi ngā taputapu whakaputa katoa i roto i te āhua kati, ā, me tirotirohia ngā paipa me ngā takirere i ia wā hei ārai i te turuturu. I muri i te mahi, me horoi pai ngā ringa me te mata o ngā kaiwhakahaere, ā, me whakawhiti kākahu mahi, ā, kaua e mau kākahu mahi poke i roto i ngā wāhi noho. Hei tāpiri, me whakatū ngā tohu whakatūpato ki te wāhi mahi, me ngā whakaurunga horoi ohorere me ngā taputapu tinei ahi, ā, me whakahaere ngā whakangungu ohorere i ia wā.
