【Whakataki】I te marama o Hūrae, ko ngā hua o te mekameka ahumahi acetone i whakaatu i te hekenga nui. Ko te kore taurite o te tuku me te tono me te koretake o te tuku utu ko ngā tino take o te hekenga o ngā utu mākete. Heoi, ahakoa te hekenga whānui o ngā hua mekameka ahumahi, haunga te pikinga iti o ngā mate hua ahumahi, i noho tonu ngā hua o te MMA me te isopropanol ki runga ake i te rārangi pakaru (ahakoa i tino pēhia hoki ā rātou hua), ko ētahi atu hua katoa i noho tonu ki raro i te rārangi pakaru.
I whakaatuhia he ia heke iho o ngā hua i roto i te mekameka ahumahi acetone i te marama o Hūrae
I heke te auau o ngā hua i roto i te mekameka ahumahi acetone i tēnei marama. Ko te kore taurite o te tuku me te tono me te koretake o te tuku utu ngā tino take o te hekenga o te mākete. Mō te whānuitanga o te hekenga, i kite te acetone i te hekenga o te marama tata ki te 9.25%, ko te tuatahi i roto i te mekameka ahumahi. I whakaatu te pikinga o te tuku o te mākete acetone ā-rohe i te marama o Hūrae: i tetahi taha, ko ētahi o ngā umanga i whakamutu i te whakaputanga i mua ake nei i tīmata anō, pērā i a Yangzhou Shiyou; i tetahi atu taha, i tīmata a Zhenhai Refining & Chemical ki te hoko hua i waho i te 10 o Hūrae, i whakararuraru i ngā kaimahi o roto o te ahumahi, i pana ai te arotahi o ngā whiriwhiringa mākete ki raro. Heoi, i te hekenga tonu o ngā utu, i pāngia ngā kaipupuri e ngā pēhanga utu, ā, i ngana ētahi ki te whakapiki ake i ā rātou whakatau utu, engari kāore i te pumau te pikinga, ā, kāore i taea e ngā rahinga tauwhitinga te tautoko.
I whakaatuhia e ngā hua heke o te acetone he hekenga nui. I roto i ēnei, ko ngā hekenga o ia marama o ngā utu toharite o te bisphenol A, te isopropanol, me te MIBK i neke atu i te 5%, i te -5.02%, -5.95%, me te -5.46%. I heke ngā utu o ngā rauemi mata phenol me te acetone, nō reira kāore i taea e te taha utu te tautoko i te umanga bisphenol A. I tua atu, i noho teitei tonu ngā reiti mahi a te umanga bisphenol A, engari i whai ngoikore te tono; i runga i te papamuri o ngā pēhanga o te tuku me te tono, i kino ake te hekenga whānui o te umanga.
Ahakoa i tautokona pai te mākete isopropanol i tēnei marama e ngā āhuatanga pēnei i te kati o Ningbo Juhua, te whakaiti i te kawenga o Dalian Hengli, me ngā whakaroa o ngā utanga hokohoko ā-rohe, he ngoikore te taha tono. I tua atu, i heke iho ngā utu o te acetone rauemi mata i raro i te 5,000 yuan/tana, ā, kāore i te tino maia ngā tāngata o roto o te umanga, nā te mea i hoko atu rātou i ngā utu iti iho, engari kāore i te tautokona ngā rahinga tauwhitinga, ā, ka heke te mākete whānui.
I noho tonu te tuku o MIBK me te rawaka, ā, kei te pāngia tonu ētahi wheketere e ngā pēhanga tuku. I whakaitihia ngā utu me te whai wāhi mō ngā whiriwhiringa tauwhitinga tuturu, i te mea he koretake te tono i raro iho, ā, i heke iho ngā utu mākete. I heke te utu toharite o MMA i te mākete tuatahi o te Rawhiti o Haina i raro iho i te tohu 10,000-yuan i tēnei marama, me te hekenga o te utu toharite o ia marama o te 4.31% i roto i te marama. Ko te hekenga o te tono i te wā kore-wā te tino take o te hekenga o te mākete MMA.
I te nuinga o te wā, he ngoikore te hua o ngā hua mekameka ahumahi.
I te marama o Hūrae, he ngoikore te hua o ngā hua i roto i te mekameka ahumahi acetone. I tēnei wā, ko te nuinga o ngā hua i roto i te mekameka ahumahi kei roto i te āhua o te tuku rawaka engari kāore i te rawaka te whai i te tono; me te tuku utu ngoikore, koinei ngā take mō ngā ngaronga o ngā hua mekameka ahumahi. I roto i te marama, ko te MMA me te isopropanol anake i pupuri i ngā hua i runga ake i te rārangi pakaru, ko ngā hua katoa i noho i raro iho. I tēnei marama, ko te hua katoa o te mekameka ahumahi i aro nui tonu ki te umanga MMA, me te hua katoa o te 312 yuan/tana, ko te ngaronga hua katoa o te umanga MIBK i whānui ake ki te 1,790 yuan/tana.
Tērā pea ka mahi ngā hua o te mekameka ahumahi acetone i roto i tētahi whānuitanga iti o ngā piki me ngā heke i te marama o Ākuhata.
E matapaetia ana ka whakahaerehia pea ngā hua o te mekameka ahumahi acetone i roto i tētahi whānuitanga iti o ngā rerekētanga i te marama o Ākuhata. I ngā rā tuatahi tekau o Ākuhata, ka aro nui ngā hua mekameka ahumahi ki te keri i ngā kirimana wā roa, me te iti o te hihiri mō te hokohoko kaha i te mākete. Ka iti te tautoko a ngā rahinga tauwhitinga ki ngā hua mekameka ahumahi. I waenganui me te mutunga o ngā rā tekau, i te mea ka piki ake ētahi o ngā hiahia hokohoko wāhi i raro iho, ā, ka tata mai te pikinga o te mākete "Hepetema Koura", ka hoki mai pea ētahi o ngā tono mutunga, ā, ka tautoko pea ngā rahinga tauwhitinga i ngā utu. Heoi, mō te whānuitanga o ngā rerekētanga i tēnei marama, he iti tonu ngā tumanakohanga.
