I-polypropylene ephezulu ibhekisela emikhiqizweni ye-polypropylene ngaphezu kwezinto ezijwayelekile (umdwebo, i-copolymerization encibilikayo ephansi, ukubunjwa komjovo we-homopolymer, i-fiber, njll.), kufaka phakathi kodwa kungagcini ezintweni ezibonakalayo, i-CPP, izinto ze-tube, imikhiqizo emithathu ephezulu.

Eminyakeni yamuva nje, i-polypropylene ephezulu isiphenduke inkundla yempi, umthamo wokukhiqiza we-PP osezingeni eliphezulu uyaqhubeka nokukhula, i-polypropylene enegwebu, i-metallocene polypropylene, i-polypropylene emithathu ephezulu, i-ultra-low ash polypropylene nezinye izinhlobo ezintsha zesabelo semakethe ziphansi, kodwa indawo yokufuna ibanzi, amandla okuthuthukiswa kwemakethe yesikhathi esizayo makhulu;Ngo-2021, ukukhishwa kwe-polypropylene ephezulu kwafinyelela kumathani ayi-7,963,400, umthamo wokungenisa wawungamathani ayi-2,399,100, kanti ukuncika kwamanye amazwe kwafinyelela ku-23.57%.Eminye imikhiqizo ibhekene nesimo esikhona se-monopoly yangaphandle futhi iqhubeka nenqubo yokuqala kusukela ekuqaleni.Isikhathi sika-2021-2025 yisigaba sokuthuthuka esithuthukayo se-polypropylene ephezulu, futhi izinga lokukhula lizokwehla ngo-2025-2030.

Phakathi nenkathi ka-2022-2030, amathani ayizigidi ezingu-35.63/ngonyaka wokufakwa kwe-polypropylene kuhlelwe ukuthi afakwe emsebenzini wezohwebo e-China, kodwa i-polypropylene esezingeni eliphezulu ihlanganisa kuphela u-30% wokwanda komthamo we-polypropylene entsha, ngakho-ke cishe izigidi ezingu-10.7 amathani.Ngaphezu kwengxenye yenqubo yebhizinisi le-PDH, ngenxa yokuthi umthombo wayo wamahhala we-ethylene ungakhiqiza i-polymer e-homogeneous kuphela, ngeke ihlukaniswe ngezigaba ze-polypropylene ephezulu ngesikhathi esifushane, futhi ingxenye yamakhemikhali okucwenga amalahle namanye amadivaysi, ngenxa yokuthi inqubo yedivayisi entsha ayizinzile, ubuchwepheshe abukavuthwa futhi ezinye izizathu zenza imboni yamakhemikhali okucwengisiswa kanye namalahle ithuthuke izinze, ngakho-ke izinto ezijwayelekile ezifana nomdwebo wezintambo ezincibilikayo ezincibilikayo zifika emakethe, azihlukaniswa njenge-polypropylene ephezulu. okwamanje;Ngokuzayo, iSinopec ne-CNPC zizonweba umthamo owengeziwe ngenxa yomlando wazo ocebile kanye nenqubo ezinzile.Isakhiwo sabo sigxile ekufuneni kwemakethe ephezulu.Esikhathini esizayo, umncintiswano we-polypropylene ephezulu uzoqhubeka nokuzungeza amafutha amabili.

Ngokwesidingo, i-polypropylene ephezulu njengamanje inesidingo esikhulu sokuguqulwa kwezimoto.Ukuthuthuka okusheshayo komqondo we-automotive lightweight kanye nezimoto ezintsha zamandla kunikeze amandla amakhulu emakethe yokuguqulwa kwezimoto.Iphuzu eliyinhloko lokukhula kwesidingo i-copolymerization ye-fusion ephezulu emaphakathi.Okwesibili ukubumba komjovo odongeni omncane.Ukupakishwa kwe-Takeout kuhlanganiswe nemikhuba yomphakathi.Imboni yokukhipha impahla ithuthuke ngokushesha ikakhulukazi ngaphansi kosizo lwemicimbi yezempilo yomphakathi.Izinga lokukhula lidlula kude izinga lokukhula eliphelele lesidingo se-polypropylene.Imboni esobala isetshenziswa kakhulu futhi inombono obanzi.Isetshenziswa kakhulu ezikhwameni zokumuselwa kwezokwelapha, izinto zokwelashwa, ezifakwa ezitsheni, emikhiqizweni yezingane, njll. Phakathi kwazo, i-medical transparent accounts cishe amaphesenti angama-40 yenani eliphelele elisobala, kulandele ukupakishwa kwesiqukathi.Ngenxa yesimo sokuguga eChina kanye nesimo sobhubhane olujwayelekile, insimbi esobala idinga ukuthuthukisa, futhi imakethe yasekhaya esobala yamanje incike kakhulu ekuthengisweni kwamanye amazwe, ngakho-ke sisekhona isikhala esikhulu sokuthuthukiswa kwemakethe yasekhaya esikhathini esizayo.Okokugcina, izinto ezisezingeni eliphezulu ezifana nefilimu ye-CPP kanambambili kanye ne-ternary copolymerization kanye nepayipi lamanzi ashisayo zilinganiselwe emakethe ngenxa yomthamo wazo wemakethe omncane kanye nomsebenzi ophansi.Ukunikezwa kwasekhaya kungabalelwa kuphela cishe amaphesenti angama-50 esabelo semakethe, futhi kusenendawo enkulu yokudlala emakethe yasekhaya.Ukufingqa, izinga lokukhula kwesikhathi esizayo lokunwetshwa komthamo we-polypropylene okusezingeni eliphezulu lingaphansi kwengcindezi yemakethe yonke ye-polypropylene, futhi isidingo semakethe sisenendawo enkulu yokuthuthukiswa, ukuhlelwa kwesikhathi esizayo kocwaningo lwe-polypropylene ephezulu kanye nokukhiqizwa kokuthuthukiswa kuphoqelekile.
