He whakarewa rauropi taiao-hoa te Methyl acetate e whakamahia whānuitia ana i roto i ngā ahumahi tae atu ki te hanga matū, te tā, te tukatuka hiako me te hanga hiko. He kakara hou, he kaha te whakarewa, he iti te parahanga me te whai hua o te utu, ā, he pai ake te whakakapi i ngā whakarewa tuku iho tino paitini. Heoi, ko tōna rongonui mō te "kakariki me te iti-paitini" he maha ngā wā ka arahi ki te koretake o te mōhio ki te haumaru, engari ko ōna mōrearea huna o te mura, te nui o te hurihuri me te wai paitini ka warewarehia. Hei āwhina i te marea me ngā kaimahi ki te mārama whānui me te pūtaiao ki te methyl acetate me te karo i ngā tūponotanga kino i te wā e whakahaerehia ana me te rokiroki, ka whakautua e tēnei tuhinga ngā pātai e pātaihia pinepine ana, ā, ka whakaratohia he mōhiotanga haumaru mahi i roto i te whakatakotoranga Q&A.
P1: He aha te methyl acetate? He aha ōna āhuatanga ā-tinana me te matū matua?
Ko te methyl acetate, e mōhiotia ana ko te acetic acid methyl ester, he matū ester mekameka poto noa. I te pāmahana rūma, he wai mārama, kāore he tae, he kakara hua hou. Ko te pāmahana koropupū he 56.7°C anake, ā, he tino pupū ake i raro i ngā āhuatanga noa. Ka taea te whakaranu ki te nuinga o ngā whakarewa waro pēnei i te etanoru me te etera, he paku wairewa ki te wai, ā, he tino pai te kaha ki te rewa mō ngā kapia, te rapa, te hinu me ētahi atu matū.
Ki te whakatauritea ki ngā whakarewa benzene tuku iho, he iti te VOC o te methyl acetate, he iti te paitini, he pai hoki mō te taiao, he iti ake ngā tukunga parahanga, ā, he mea whakakapi matomato matua i roto i te umanga. Heoi anō, e rua ngā mōrearea haumaru nui. Tuatahi, he tino mura, ā, ka taea e tōna kohu pupuhi te hanga ranunga pahū me te hau. Tuarua, he ngoikore te pumau matū. Ina pāngia ki te wai, ki te pāmahana teitei rānei mō te wā roa, ka pāngia e te waikura hei whakaputa waikawa acetic me te methanol paitini, ka puta he mōrearea hauora pea e wehewehe ana i a ia mai i ngā whakarewa noa e pai ana mō te taiao.
P2: He aha ngā whakamahinga matua me ngā āhuatanga o ia rā mō te methyl acetate?
Nā te pai o te mahi taiao me te kaha ki te whakarewa, ka whakamahia whānuitia te methyl acetate i roto i ngā ahumahi hanga, hanga māmā me ngā ahumahi matū pai. I roto i te ahumahi, e whakamahia whānuitia ana hei tango hinu me te horoi mō ngā wāhanga hiko me ngā taputapu tino tika, tae atu ki te wairewa i roto i te tango hinu hiako, te hiako horihori me te tukatuka rapa. I roto i te ahumahi tā me te tākai, ka mahi hei wairewa taiao iti-kakara mō ngā waituhi me ngā piripiri, ā, ka taea te whakamahi ki ngā rauemi tākai e pā ana ki te kai.
I roto i te oranga o ia rā, ka tāpirihia te methyl acetate ki ngā hua pēnei i te peita whao, ngā piripiri rehu me ngā patu pepeke hei whakarewa tere maroke. Ko te pānga iti ki ngā hua o ia rā kua tohua, kāore he mōrearea ki te tangata noa. Ko ngā kaimahi o te rārangi mua i roto i ngā awheawhe tā, matū me te hiako ngā rōpū matua e pāngia ana, e pā tonu ana ki te kohu pūngāwerewere, ā, me tiaki paerewa.
Q3: He aha ngā tūponotanga hauora me ngā tohumate paihana o te methyl acetate?
He iti noa te paitini o te methyl acetate, ā, ka taea te tere te whakapūngao e te tinana tangata i muri i te pānga iti i ētahi wā. Heoi, ki te roa te pānga, ki te nui te kukū, ka nui pea te kino, mā te manawa manawa me te pā ki te kiri. Ki te manawa poto i te kohu nui te kukū, ka whakapataritari i ngā kiriuhi mucous o ngā kanohi, ihu me te korokoro, ka puta te roimata, te maroke o ngā kanohi, te mamae o te korokoro me te maremare. Ka pehia hoki e ia te pūnaha io matua, ka puta te whanoke, te hiamoe, te ngenge me te kikī o te uma.
Ko te roa o te wā e pāngia ana e te kore tiaki ka nui ake ngā tūponotanga huna. Ka puta te riri mau tonu o te mucosa me te mamae tonu o te manawa mēnā ka manawahia tonutia. Heoi anō, ka huri haere te toenga methyl acetate i roto i te tinana hei methanol, ā, ka roa te kohikohinga ka kino pea te io whatu, ka pōuri te tirohanga me te whakaiti i te tirohanga. Ka tangohia e te kiri te hinu o te kiri i te wā e pā ana ki te kiri, ka kino te ārai kiri, ā, ka maroke, ka taratara, ka kiri me te kiri pā. Ka puta pea te narcosis me te pehanga manawa i te wā e tino kukū ana te matū. Ka puta pea he tūponotanga nui ki te haumaru.
P4: Me pēhea te whakatutuki i te tiaki pūtaiao i te wā e mahi ana? He aha ngā mahi āwhina tuatahi mō te pānga ohorere?
Ka taea te ārai katoa i ngā mōrearea o te methyl acetate mā te tiaki paerewa, e aro ana ki te ārai ahi, te ārai manawa me te ārai pā ki te kiri. Me pupuri tonu te hauhautanga o ngā awheawhe me ngā taputapu whakaputa hau whai hua hei ārai i te nui o te kohu. Me mau ngā kaiwhakahaere i ngā kopare ārai-paitini, ngā karapu ātete-whakarewa me ngā mōhiti tiaki, ā, kāore e whakaaetia te pā tika ki te kiri me te manawa tata o te kohu. Kāore e whakaaetia te mura tuwhera me ngā pūtake wera pāmahana teitei i roto i ngā wāhi mahi hei whakakore i ngā mōrearea mura me ngā mōrearea pahū. Me tirotiro hauora mahi auau ngā kaimahi roa kia kitea ai te kino pea o te io me te kanohi i te wā tōmua.
Me whakakore wawe, me te whakarite hoki i te pānga o te matū ki te tinana. Horoia rawatia te kiri kua pangia ki te hopi me te wai rere. Horoia tonutia ngā kanohi ki te wai ma, ā, rapua he awhina hauora mēnā ka mau tonu te mamae. Nekehia tonutia ngā tāngata e pāngia ana e ngā tohu manawa ki te hau hou, kia kore ai e araia te manawa. Mēnā ka horomia noatia, kaua e akiaki kia ruaki hei karo i ngā whara tuarua pērā i te niumōnia manawa, ā, rapua tonutia he awhina hauora.
Q5: He aha ngā tapu mō te rokiroki me te kawe i te methyl acetate?
He matū morearea mura, he tino pūngāwerewere hoki te methyl acetate, me penapena kia rite tonu ki ngā ture e tika ana. Me hiritia kia mau, ka whakatakotoria ki roto i tētahi whare putunga ngaio matao, maroke, me te hauhautanga pai, kia matara atu i ngā pūtake wera, i ngā mura tuwhera, me te rā tika. Kāore e whakaaetia te penapena ranunga me ngā waikura, ngā waikawa, ngā kawakore rānei hei ārai i ngā tauhohenga matū morearea. Me karo hoki i ngā taiao makuku hei ārai i te waikura me te whakaputanga o ngā matū paitini i muri mai.
E taunakihia ana kia rongoatia ngā ipu whakarewa, ngā ipu karāhe rānei, engari kāore e whakaaetia ngā ipu kirihou nā te mea ka waikura pea, ka turuturu rānei. I te wā e kawe ana, me mau tonu ngā ipu kia kore ai e turuturu nā te pakaru, me te tiaki katoa i te ahi, te pānga o te rā me te urunga mai o te wai ua. Hei whakamutunga, he whakarewa ahumahi kounga teitei, he pai hoki mō te taiao, he nui ngā painga me ngā tūponotanga pea. Mā te piripono ki ngā whakaritenga whakahaere, rokiroki me te tiaki ka taea te whakakore i ngā tūponotanga huna, ā, ka whakarite kia haumaru, kia whai hua hoki te whakamahinga.
