[Gwaro]: Pakupera kwaChikumi, kuvharwa kusingatarisirwi kwemidziyo yemusika wepropylene kwakaitika chimwe nechimwe, izvo zvaive zvakanaka kune divi rekugovera, nepo kufarira kwezvigadzirwa zvepasi pemvura kwakawedzera, uye mutengo wemusika wakamira kudonha, kubva munaChikunguru 14, mutengo wemusika weShandong propylene waive 6480-6500 yuan/tani, uye mutengo wemusika weEast China waive 6350-6350 yuan/tani.

Muchikamu chino, musika wepropylene wemuno wamira kudzikira uye wadzoka, uye zvinhu zvinotsigira kukwira kwemusika zviri kunyanya muzvinhu zvakakosha zvekupa nekudiwa. Mitengo yemafuta yepasi rose yakakwira, zvinhu zvikuru zvakanaka ndeizvi: data rekuwedzera kwemitengo yemafuta muUnited States rakanaka, Federal Reserve icharamba ichikwidza kumanikidzwa kwemitengo yemubereko kwadzikira, uye kudzikiswa kwekugadzirwa kweSaudi Arabia kwakaunza kuenderera mberi kwemamiriro akanaka, kumusika. Panguva imwe chete, kupaka kwechinguva kwemidziyo yepropylene yeQingdao Jinneng, Wangtong, uye Zhenghe munzvimbo iyi, nepo mudziyo wekugadzirisa wekupaka usati watangwazve, uye kugoverwa kuri kutarisana nemusika nerutsigiro rwakati, uye mwero wekugadzira wePDH wenyika yose uri 69.79% kubva pamazuva gumi nemana, ari 0.2% pasi pane kutenderera kwapfuura. Nekudzikira kwekuvakwa kwepropylene, huwandu hwemakambani ekugadzira propylene hauna kukwira zvakanyanya, mutengo wekupa unosimudzwa zvishoma nezvishoma, kufarira kutenga kuri nani, uye mamiriro ekutengeserana ese akanaka.

Muchikamu chino, maitiro matatu epropylene akasanganiswa, uye purofiti yepropane dehydrogenation kuenda kupropylene iri pachena. Kune rumwe rutivi, mutengo wepropane unoramba uchidzikira padanho iri, uye kune rumwe rutivi, mutengo wepropylene monomer wakasimba, izvo zvinoita kuti purofiti iwedzere. Purofiti ye naphtha ne methanol kuenda kupropylene yakaramba ichidzikira, uye purofiti ye methanol kuenda kupropylene yakadzikira zvakanyanya, izvo zvakanyanya kukanganiswa nemutengo we methanol yezvinhu zvakagadziriswa, izvo zvakatadzisa purofiti. Purofiti yepropylene kuenda ku naphtha inowanzo kudzikira kubva svondo rapfuura, chinhu chikuru chinopesvedzera mutengo we naphtha wakaderera kumusoro, asiwo pakudhonza purofiti kunokonzerwa, kunotarisirwa kuti purofiti yepropylene iwedzere kwenguva pfupi, kunonoka kunyatsoteerera mutengo wemusika wezvinhu zvakagadziriswa.

Munguva pfupi, kudivi rekugovera, nekutangwazve kwemidziyo yePDH muShandong, mutoro wezvinhu zvitsva zvinogadzirwa pakutanga unowedzera zvishoma nezvishoma, uye huwandu hwezvinogadzirwa nepropylene hunotarisirwa kuwedzera, asi nzvimbo yekupaka mota yezvigadzirwa zvemafekitori ega ega muShandong ichapa musika simba. Kudivi rekuda, padanho rino, musika wepolypropylene unowanzova nemafambiro akasimba, purofiti yehupfu yakanaka, mafekitori epasi anongoda kutenga zvakanyanya, nepo vhiki rinouya PO, fekitori yeacrylonitrile inotarisirwa kutangazve, zvinotarisirwa kuti musika wepropylene wenguva pfupi ungave nekuwedzera kudiki, asi nzvimbo yekukwira ishoma, tevera zvakanyanya kutangazve nekutumirwa kwevagadziri vepropylene.

Kudivi rekuda, mafambiro emusika wepolypropylene mudenderedzwa, rutsigiro rwedivi rekuda rwakasimba, mutengo wepropylene usati waiswa wakaderera, kupararira pakati pepropylene nePP kwakawedzera, purofiti yefekitori yakawedzera zvishoma nezvishoma, kufarira kutenga kwakawedzerawo zvishoma nezvishoma, zvakaita kuti mabhizinesi epropylene atumirwe zvakanaka, nzvimbo yezvinhu zviri muchitoro ichi iwedzere zvishoma nezvishoma, mitengo yepropylene yakakwira.
