I tēnei marama, me te whakaurunga o ngā kaupapa here maha, te pikinga o te mākete polypropylene, te pikinga o te utu, te pikinga o te utu i roto i te kōpae i te wā poto, me te pikinga o te tono me te tuku mō te wā poto, kua paku whakawhāitihia te tautoko o te hokinga mai, engari ko te wāhi me te pikinga whānui. I te taha tono, ko te tukunga pai o te macro, me nui ake te wā ki te tirotiro i te whakaoranga tono tūturu, kei te wā kore te tono o nāianei, ehara i te mea ngāwari ki te tino tumanako i te wā poto, ahakoa he tautoko kei te kare ā-roto kōpae, engari kāore i tino rerekē te ia o ia marama. Ko te pumau me te teitei o te pikinga i puta mai i te whakapainga o te tono he iti noa iho. Nō reira, ko te hokinga mai o te PP mō te wā poto he tino nui, he āta rānei, ā, ka mau tonu te tirohanga whakaheke i muri i te hokinga mai.

I te marama o Hune, ko te tapeke o te polypropylene i Haina he 2,603,800 tana, he pikinga o te 43,100 tana i whakaritea ki te marama o Mei, +1.68% ia marama, +7.40% ia tau. I roto i te marama, ka tīmata te wahanga tuarua o te kamupene nui a Zhengyuan ki te whakaputa papatipu, ka whakaroa tonu a Donghua Maoming, ka hokona te taputapu polypropylene 300,000 tana/tau a Anqing Petrochemical i te whakamātautau 22, ā, ka hokona i te marama o Hūrae. Nā te hokinga mai o te ōhanga o ētahi taputapu, kua tīmata anō ngā taputapu tiaki, ā, kua piki ake te tuku o te mākete mai i te marama o Mei.

I te marama o Hūrae, ko ngā taputapu tiaki kua whakaritea ko Zhongke Refining me te raina matū tuatahi, Donghua Energy (Zhangjiagang), me ētahi atu, ā, ko ngā taputapu taraiwa ko Daqing Petrochemical, te raina tuarua o Luoyang Petrochemical, Yan 'an Refinery, Shanghai Secco, Daqing Hading, Daqing Refining me te raina tuarua o te matū, me ētahi atu. Ko Hūrae te wā kai tuku iho mō te polypropylene, ā, e tautokona ana te mākete polypropylene o nāianei e te taumata whānui, kei te piki haere ngā utu polypropylene, kei te whānui haere ngā tawhē hua o ngā umanga whakaputa, ā, kua heke te hiahia ki te whakahou. Nō reira, e matapaetia ana ka heke te ngaronga tiaki o ngā taputapu polypropylene ā-whare i te marama o Hūrae. Kia aro ki te whakamutu wā poto i ngā taputapu tiaki.

I tēnei wā, kei te wā kore-wā tonu te hekenga o te whenua, kāore i te pai te haere tonu o te tono, ā, he uaua ki te pupuri i te hua kua oti. Ko te iti o te rawa o ngā rauemi mata o nāianei, me te whakaaro poto mō ngā kaupapa here hoko whenua, ko te tono ā-muri hei tautoko, kua tata te taenga ki Hūrae, ko te wā tihi i mua i te hoko hei hoatu i ngā tumanakohanga whakapai ake i te mākete, ko te haurua tuarua o te tau kei te wāhanga kaha o te kai, ko ngā motuka, ngā taputapu kāinga e kaweake ana me te tono ā-rohe kei te kaha tonu, e matapaetia ana ka tautoko i te tono copolymerization hanumi teitei i roto i te wā poto, he kaha te ohorere o te pūtake copolymerization hanumi teitei i mua i te ru, me aro ki ngā huringa ota.

I te marama o Hūrae, i te whakatikatika i ngā hua o ngā umanga whakaputa tata nei, i tere ake te tūponotanga o ngā taputapu hou, i iti te tiaki i ngā taputapu taketake, ā, i āta puta te pēhanga tuku. I te taha kaupapa here, kei te haere tonu te taha whenua ki te whai i ngā whakaohooho purongo koretake, me te pakū anō o ngā purongo whakaheke reiti huamoni, i raro i ngā raraunga ōhanga ngoikore, ka hangaia e te kēmu i te taha kaupapa here he tautoko mō ngā utu i te wā poto, i runga i ngā kaupapa matua o te PP, ko te ngoikore o te mooni ka arahi ki te iti o te wāhi i runga ake i te utu, me ngā ohorere tonu i te wā poto. I te wā waenga, me iti tonu ngā utu o te mākete hei whakataurite i te taupatupatu i waenga i te kaha hou me te tono ngoikore, nō reira ka haere tonu te piki me te heke o te wā poto.
