Arataki: Mai i te marama o Hepetema, kua whakaatu te mākete propylene oxide ā-rohe i te pikinga tonu, i te tīmatanga o te marama, i te tumanako o ngā rōpū katoa o te mākete mō te wā tihi o te "koura e iwa", kua piki tonu te mākete, engari kua piki ki te 9550-9670 yuan/tana (te wheketere whakawhiti wāhi o Shandong), kua huri te mākete kia tūpato, ki tētahi taumata, kua pā ki te maia o te umanga, i te mutunga wiki whakamutunga i muri i te hekenga tika o te cyC, nā te utu o te kukume kitea, ka mutu wawe te hinga o te mākete, ā, ka tīmata anō tētahi atu huringa o te mākete pikinga, mai i te 15 o Hepetema, ki te 9650-9750 yuan/tana, ka tae ki te taumata tiketike i te haurua tuarua o te tau, ā, ka puhoi te tipu whānui.

Tuatahi, kua whakaatuhia e te reiti whakamahi kaha taha tuku he ia o te whakaoranga

I waenganui o te tīmatanga o Hepetema, ko te reiti whakamahinga kaha o te mākete propylene oxide ā-rohe kua mau tonu ki te taumata iti o te 60%-65%, ā, he maha ngā taputapu pēnei i a Jincheng Petrochemical, Taixing Yida, Wanhua Phase I, Tianjin Bohua kei roto i te āhua waka, me te tiaki poto me te whakaiti i ngā taputapu kaha nui pēnei i a Xinyue me Jiahong, me ētahi atu, he iti te tuku mākete, ā, kua tautokona hoki te utu.

I te wiki kua taha ake nei, i piki ake te mahi kino a Xinyue me Jiahong, me te tīmatanga anō o te taputapu wāhanga tuatahi o Wanhua, tae noa ki te 15 o Hepetema, kua piki ake te reiti whakamahinga kaha o te umanga ki te 71.50%, he pikinga o te 5.79 ōrau i whakaritea ki te tīmatanga o te marama, ko te tipu whakaputa o ia rā o te 0.1 miriona tana, i te mea kei te tuku utanga kaipuke matū hinu a Zhejiang ki te tauranga i te taha rawhiti o Haina, ā, he tāpiritanga motuhake kei te rohe.

I te whai ake, kāore he mahere rerekētanga mō te maha o ngā taputapu kei te papaanga, ā, ka tīmata a Jincheng Petrochemical ki te hoko hauwai waikura, engari kāore anō kia tino mārama te tīmatanga o tana taputapu HPPO 300,000 / tau, me aro tonu ki te tuku katoa e tika ana kia pumau i mua i te hararei.

Tuarua, kei te piki haere tonu te nui o ngā rauemi mata

Mai i te tirohanga utu, i te wiki kua taha ake nei, kua tino piki ake ngā rauemi mata matua o te propylene me te chlorine wai i roto i te tikanga chlorohydrin, kua eke ki te taumata teitei rawa atu i roto i te tau, ahakoa kua piki ake te utu o te cyclopropylene ki tētahi taumata, engari kāore te tere tipu i te tere rite ki te utu, ā, kua whānui ake te nui o te mate i whakaritea ki te tīmatanga o te marama, i tēnei huringa o te mākete piki, he kaha te pānga pai ki te utu, me te tukanga HPPO, nā te mea kua piki ake te utu o ngā rauemi mata noa o te propylene. Ka tatauhia te hauwai peroxide kia rite ki te utu taputapu ariā, ā, ka whakaitihia te rerekētanga utu i waenga i ngā tukanga e rua, engari kei te piki tonu te utu o te hauwai peroxide, ā, me aro ki te pānga ki ētahi tukanga HPPO ki te whakarerekē i te kawenga o tā rātou ake taputapu cyclopropyl me te hoko hauwai peroxide ki tāwāhi.

I tēnei wiki, e matapaetia ana ka whakakotahi te propylene me te chlorine wai ki tētahi taumata teitei, ā, e matapaetia ana i raro i te mākete whakakī wāhanga i mua i te hararei, kei te tautoko tonu te mākete cycloC.

Tuatoru, ko te taha tono o te tatari-me-te-kite iti piki haere te tupato ki te utu nui

Mō te tono o raro iho, he pai tonu te mahi a ngā ota hou o te polyether i te wā tihi o te "koura e iwa" engari kāore i rite ki ngā tumanakohanga, ki te whakaritea ki te mākete i te marama o Hūrae-Ākuhata, kāore he whakapainga nui, whai muri i te mātakitaki i te hekenga o CIC ki raro i te wiki kua hipa, he iti noa te haere tonu o te pikinga kotahi hou o raro iho, ko te nuinga i runga i te tukunga o ngā ota wawe, ā, whai muri i te mātakitaki i ngā utu teitei o CIC, ka puhoi te auau hoko. He pai te hua o te umanga propylene glycol, ā, he nui ake te rerekētanga o te taputapu, ā, he iti noa te pānga.

I te whai ake, e rua wiki tonu mai i te hararei 11, i tēnei huringa o te mākete piki ake, kua taurite te nui o ngā taonga a ētahi kaihoko, ā, he iti tonu te tono i tēnei wiki, ā, kua tata te mutunga o te marama ki te wā hararei, ā, e matapaetia ana ka hararei te mākete tetahi i muri i tetahi.

Tuawhā, ka pōturi pea te pikinga i mua i te hakari whakapūmau, i te whānuitanga whaiti rānei.

Whakatau (wā poto): I te wiki kua taha ake nei, i piki ake te utu mākete ki tētahi taumata teitei hou i te haurua tuarua o te tau, ā, i ngā wā tata nei, e matapaetia ana ka hoki anō te tūponotanga ki te pumau, i tēnei wiki, he iti tonu te tono hea mō te mutunga polyether, e matapaetia ana ka tūpono a CIC, tata ki te mutunga o te marama, ka tautokohia e ngā rōpū te ngoikore, ka heke rānei ngā tumanakohanga.

Whakatau (wā waenga me te wā roa): I te marama o Oketopa, me aro tātou ki ngā rerekētanga o ngā taputapu rerekē i te wā hararei, e matapaetia ana ka tīmata anō a Tianjin Bohua i muri i te hararei, tera pea he tumanakohanga tiaki a Shandong Jinling, ka hoki ki te awhe whaiti i muri i te whakarite o te taonga, ā, i te haurua tuarua o te tau, me aro ki ngā whanaketanga motuhake mō te tiaki Shell.

Whakatūpato mōrearea: te koretake o te pūnga wā piki haere o te mata o te taputapu; Mena ka piki te pēhanga utu i muri i te hihiri o te umanga ki te tīmata; te taunga o te kai tūturu taha tono.
