I tēnei wiki, i heke te nuinga o te wā i waenganui i te utu o ngā hua i roto i te mekameka ahumahi phenol-ketone. Nā te ngoikore o te whakawhiti utu, me te pēhanga o te tuku me te tono, i puta ai he pēhanga whakatikatika ki raro i runga i ngā utu mekameka ahumahi. Heoi, i whakaatu ngā hua o runga i te ātete ki raro nui atu i ngā hua o raro, ā, i heke ai te hua puta noa i ngā ahumahi o raro. Ahakoa i whaiti te taha mate o te ahumahi phenol-ketone o waenganui, i noho ngoikore tonu te hua whānui o ngā hua o runga me waenganui, i te mea kei te mau tonu te hua o ngā ahumahi MMA (Methyl Methacrylate) me te isopropanol o raro.
Mō ngā utu toharite ia wiki, haunga te pikinga iti o te utu toharite ia wiki o te phenol (he hua takawaenga), ko ngā hua katoa i roto i te mekameka ahumahi phenol-ketone i heke, ko te nuinga i heke i roto i te awhe o te 0.05% ki te 2.41%. I roto i ēnei, ko ngā hua o runga ko te benzene me te propylene, ā, ko ō rātou utu toharite ia wiki i heke mā te 0.93% me te 0.95% ia marama. I roto i te wiki, whai muri i ngā pikinga iti, i kite ngā utu hinu mata i te hekenga poto. I noho puhoi tonu ngā āhuatanga o te mākete mutunga, ā, i kaha te whakaaro tupato o raro. Heoi, nā te tono ranunga penehīni o Amerika i piki ake ngā utu toluene, ā, i katihia ngā waeine disproportionation nā te kore o ngā painga ōhanga, i arahi ai ki te hokinga mai o ngā utu benzene i te mutunga o te wiki. I taua wā, ko ētahi waeine propylene o raro i tīmata anō te mahi, i whakapakari ake i te tautoko tono mō te propylene. I te nuinga, ahakoa i whakaatu te mutunga o ngā rauemi mata i te ngoikore o te ia, he iti ake te hekenga i tērā o ngā hua o raro.
Ko ngā hua waenga, arā, ko te phenol me te acetone, i hokohokohia ki te taha, me ngā pikinga iti o ngā huringa utu toharite ia wiki. Ahakoa te ngoikore o te whakawhiti utu, i tīmata anō ētahi o ngā waeine bisphenol A o raro i ngā mahi, ā, i tumanakohia kia tiakina ngā waeine phenol-ketone a Hengli Petrochemical i te wā o muri mai. I honoa ngā āhuatanga roa me ngā āhuatanga poto i roto i te mākete, ā, i puta ai he taupatupatu i waenga i ngā kaihoko me ngā kaihoko. I kitea e ngā hua o raro he ia heke nui ake i te mutunga utu nā te nui o te tuku me te korenga o te whakapainga o te tono mutunga. I tēnei wiki, i heke te utu toharite ia wiki o te umanga MMA o raro i te 2.41% ia marama, ko te hekenga wiki nui rawa atu tēnei i roto i te mekameka ahumahi. Ko te nuinga o tēnei nā te ngoikore o te tono mutunga, ā, i hua ake ai he nui te tuku mākete wāhi. Ina koa, i pāngia ngā wheketere o Shandong e te pēhanga nui o ngā taonga, ā, me whakaiti i ngā utu hei whakaoho i ngā tuku. I pāngia hoki ngā umanga bisphenol A me te isopropanol o raro i ētahi ia hekenga, me ngā hekenga utu toharite ia wiki o te 2.03% me te 1.06% ia, i te mea kei te noho tonu te mākete i roto i te huringa ngoikore o te whakatikatika taumata iti i waenga i te pēhanga tuku me te tono.
Mō te hua o te umanga, i te wiki nei, i pāngia e te pānga heke o te pikinga o te pēhanga o te tuku me te tono i roto i ngā umanga o raro me te ngoikore o te whakawhiti utu, i whakaatu te hua o ngā hua o raro i roto i te mekameka umanga i te ia heke. Ahakoa i pai ake te tawhē mate o te umanga phenol-ketone waenga, i tino heke te hua whānui o te mekameka umanga, ā, ko te nuinga o ngā hua i roto i te mekameka i noho tonu i roto i te āhua o te mate, e tohu ana i te ngoikore o te hua o te mekameka umanga. I roto i a rātou, ko te umanga phenol-ketone te mea i tuhi i te pikinga nui rawa atu o te hua: ko te mate o te umanga i tēnei wiki ko te 357 yuan/tana, he whakawhāiti mā te 79 yuan/tana i whakaritea ki te wiki kua hipa. Hei tāpiri, ko te hua o te umanga MMA o raro te mea i tino heke, me te toharite o te hua whānui o te umanga ia wiki i te 92 yuan/tana, he hekenga o te 333 yuan/tana mai i te wiki kua hipa. I te katoa, he ngoikore te hua o nāianei o te mekameka umanga phenol-ketone, me te nuinga o ngā hua kei te mau tonu i roto i ngā mate. Ko ngā umanga MMA me te isopropanol anake he hua o raro kei runga ake i te rārangi pakaru-taurite.
Arotahi Matua: 1. Mō te wā poto, tera pea ka mau tonu te ahua pōturi me te ngoikore o ngā utu hinu mata ā-mua, ā, e matapaetia ana ka heke tonu ngā utu ngoikore. 2. Kei te mau tonu te pēhanga tuku o te mekameka ahumahi, engari kei te iti rawa ngā utu o ngā hua mekameka ahumahi mō ngā tau maha, nō reira tera pea he iti noa te wāhi heke o te utu. 3. He uaua ki ngā ahumahi kaiwhakamahi mutunga te kite i te whakapainga nui, ā, tera pea ka haere tonu te tono ngoikore ki te tuku urupare kino ki mua.
