I te tau 2025, i whakaatuhia e te umanga styrene tētahi ia o te "hekenga tuatahi, kātahi ka ora anō" i waenganui i te hononga i waenga i te tukunga kaha kukū me te rerekētanga hanganga tono. I te hekenga paku o te pēhanga taha tuku, ka mārama haere ngā tohu o te hekenga o te mākete. Heoi, kāore anō kia whakatauhia te taupatupatu hanganga i waenga i ngā taonga nui me te rerekētanga tono, ā, ka whakawhāiti i te wāhi mō te hokinga mai o te utu.
Ko ngā ohorere o te kaha i te taha tuku te mea matua i pā ki te mākete i te haurua tuatahi o te tau. I te tau 2025, i puta mai he kaha whakaputa styrene hou ā-rohe i runga i te huarahi kukū, me te kaha hou i tāpirihia i ia tau neke atu i te 2 miriona tana. Ko ngā kaupapa whakakotahitanga matū me te whakamahine nui pērā i a Liaoning Baolai me Zhejiang Petrochemical i whai wāhi ki ngā pikinga nui, i akiaki i te tipu kaha tau-ki-te-tau o te 18%. Ko te tukunga kaha kukū, me te wā kore-wā tuku iho mō te tono i te hauwhā tuatahi, i whakanui ake i te kore taurite o te tuku-tono mākete. I heke tonu ngā utu styrene mai i te 8,200 yuan ia tana i te tīmatanga o te tau, ka eke ki te iti rawa o te tau o te 6,800 yuan ia tana i te mutunga o Oketopa, e tohu ana i te hekenga 17% mai i te tīmatanga o te tau.
I muri i waenganui o Whiringa-ā-rangi, ka piki haere te mākete i tētahi pikinga ā-wāhanga, me te pikinga o ngā utu ki te 7,200 yuan ia tana, he pikinga tata ki te 6%, e tohu ana i te putanga tuatahi o ngā āhuatanga o te hekenga. E rua ngā āhuatanga matua i akiakihia ai te pikinga. Tuatahi, i heke te taha tuku: e toru ngā huinga tipu me te katoa o te kaha ā-tau o te 1.2 miriona tana i Shandong, Jiangsu me ētahi atu rohe i whakamutua ngā mahi mō te wā poto nā te tiaki taputapu, te ngaronga hua rānei, ka heke te tere mahi ā-wiki mai i te 85% ki te 78%. Tuarua, i tautokohia e te taha utu: nā te pikinga o ngā utu hinu o te ao me te hekenga o ngā taonga tauranga, i piki ake te utu o te benzene rauemi whāngai mā te 5.2%, ka piki ake te utu whakaputa o te styrene. Ahakoa rā, ko ngā taonga teitei tonu te herenga matua. I te mutunga o Whiringa-ā-rangi, i eke ngā taonga styrene i ngā tauranga o te Rawhiti o Haina ki te 164,200 tana, 23% teitei ake i te wā kotahi o te tau kua hipa. I noho tonu ngā rā hurihanga taonga ki te 12 rā, he nui atu i te awhe whaitake o te 8 rā, ka aukati i ngā pikinga utu.
Nā te rerekētanga o te tauira tono kua kaha ake te uaua o te mākete, ā, kua hua ake he "mahi taumata-rua" puta noa i ngā rāngai matua o raro. Ko te umanga ABS (Acrylonitrile-Butadiene-Styrene) te mea nui rawa atu: i te whai huatanga mai i te tipu haere o ngā kaweake o ngā waka hiko hou me ngā taputapu kāinga atamai, i piki ake tana tono ā-tau mā te 27.5% i ia tau. I pupuri tonu ngā kaihanga ABS nui o te whare i te tere mahi neke atu i te 90%, ā, i puta ake te tono hoko pumau mō te styrene. He rerekē rawa atu, i pāngia ngā umanga PS (Polystyrene) me te EPS (Polystyrene Whakawhanui) e te puhoi o te tono i raro, nā te ngoikore roa o te mākete hoko whare. Ko te EPS te nuinga e whakamahia ana i roto i ngā rauemi whakamarumaru pakitara o waho; ko te hekenga 15% i ia tau i roto i ngā tīmatanga hanga hou o te hoko whare i hua ake ai te mahi a ngā kaihanga EPS i raro iho i te 50% te kaha. I taua wā, i kite ngā kaihanga PS i tā rātou tere mahi tata ki te 60%, he iti iho i te taumata o te wā kotahi i te tau kua hipa, nā te puhoi o te tipu kaweake o ngā umanga māmā pēnei i te takai me ngā taonga takaro.
I tēnei wā, kei roto te mākete styrene i tētahi wā taurite e tohuhia ana e te "whakaitinga o te tuku e whakarato ana i te turanga me te rerekētanga o te tono e whakawhāiti ana i te pūmanawa piki". Ahakoa kua puta ake ngā āhuatanga o te raro, kei te tatari tonu te nekehanga mō te hurihanga ki te whakakorenga whai hua o ngā taonga me te whakaoranga katoa o te tono. I roto i te wā poto, i raro i ngā here o te kawe waka hotoke i runga i ngā hua matū me te tīmatanga anō o ētahi tipu tiaki, e matapaetia ana ka huri te mākete ki te taha. I roto i te wā waenga ki te wā roa, me aro ki te pānga whakanui o ngā kaupapa here hoko whenua whakangāwari ki te tono PS me te EPS, me te whakawhānui ake i te tono ABS i roto i te rāngai hangahanga teitei. Mā ēnei āhuatanga e whakatau tahi te teitei o te hokinga mai o te utu styrene.
