I-polypropylene ephezulu ibhekisela kwiimveliso ze-polypropylene ngaphezu kwezinto eziqhelekileyo (umzobo, i-copolymerization encibilikayo ephantsi, i-homopolymer injection molding, i-fiber, njl.), kubandakanywa kodwa kungaphelelanga kwizinto ezibonakalayo, i-CPP, izixhobo ze-tube, iimveliso ezintathu eziphezulu.

Kwiminyaka yakutshanje, i-polypropylene ephezulu ibe yindawo yedabi, umthamo we-PP wesiphelo esiphezulu uyaqhubeka nokukhula, i-polypropylene egwebu, i-metallocene polypropylene, i-polypropylene ezintathu eziphezulu, i-ultra-low-low ash polypropylene kunye nezinye iintlobo ezintsha zezabelo zentengiso ziphantsi, kodwa indawo yemfuno ibanzi, amandla ophuhliso lwemarike yexesha elizayo makhulu;Ngo-2021, imveliso ye-polypropylene ephezulu ifikelele kwi-7,963,400 yeetoni, umthamo wokungenisa wawuyi-2,399,100 yeetoni, kwaye ukuxhomekeka kokungenisa kumazwe angaphandle kufikelele kwi-23.57%.Ezinye iimveliso zijongene nemeko yemonopoly yangaphandle kwaye zihamba kwinkqubo yokuqala ukusuka ekuqaleni.Ixesha le-2021-2025 linqanaba lophuhliso olukhulayo lwe-polypropylene ephezulu, kwaye izinga lokukhula liya kuncipha kwi-2025-2030.

Ngexesha le-2022-2030, i-35.63 yezigidi zeetoni / ngonyaka wofakelo lwe-polypropylene zicetywa ukuba zifakwe kwishishini lezorhwebo e-China, kodwa i-polypropylene ephezulu i-akhawunti kuphela malunga ne-30% yokwandiswa komthamo omtsha we-polypropylene, ngoko malunga ne-10.7 yezigidi. iitoni.Ukongeza kwinxalenye yenkqubo yeshishini lePDH, ngenxa yokuba i-ethylene yayo yamahhala inokuvelisa kuphela i-polymer e-homogeneous, ayiyi kufakwa kwimigangatho ye-polypropylene ephezulu ngexesha elifutshane, kunye nenxalenye yekhemikhali yokucoca amalahle kunye nezinye izixhobo, ngenxa yokuba inkqubo yesixhobo esitsha ayizinzanga, itekhnoloji ayikavuthwa kwaye ezinye izizathu zenza ushishino lwemichiza yokucoca kunye namalahle luzinze ngakumbi, ngoko ke izixhobo eziqhelekileyo ezinjengomzobo wocingo olusezantsi lokunyibilika kwecopolymerization zibethe kwimarike, azihlelwa njengepolypropylene ephezulu. ngeli xesha;Kwixesha elizayo, iSinopec kunye ne-CNPC ziya kwandisa amandla amaninzi ngenxa yembali yabo ecebileyo kunye nenkqubo ezinzileyo.Uyilo lwabo lujolise kwimfuno yemarike ephezulu.Kwixesha elizayo, ukhuphiswano lwe-polypropylene ephezulu luya kuqhubeka lujikeleza kwiioli ezimbini.

Ngokwemfuno, i-polypropylene ephezulu ngoku ikwimfuno enkulu yokuguqulwa kweemoto.Uphuhliso olukhawulezayo lwengqikelelo yemoto ekhaphukhaphu kunye neenqwelo zamandla amatsha zinike amandla amakhulu kwimarike yokuguqulwa kweemoto.Eyona ndawo iphambili yokukhula kwemfuno yi-medium-high fusion copolymerization.Eyesibini kukubumba inaliti eludongeni.Ukupakishwa kwe-Takeout kudityanisiwe kwimikhwa yentlalo.Ishishini lokukhupha liye laphuhla ngokukhawuleza phantsi koncedo lweziganeko zempilo yoluntu.Izinga lokukhula lilodlula kakhulu izinga lokukhula lilonke lemfuno yepolypropylene.Ushishino oluselubala lusetyenziswa ngokubanzi kwaye lunethemba elibanzi.Isetyenziswa ikakhulu kwiibhegi zokungena zonyango, izixhobo zonyango, ukupakishwa kwesikhongozelo, iimveliso zeentsana, njl.njl. Phakathi kwazo, i-akhawunti ecacileyo yezonyango malunga ne-40% yemali engabonakaliyo, ilandelwa yi-container packaging.Ngenxa yokuguga e-China kunye nemeko yobhubhane oluqhelekileyo, intsimbi ecacileyo kufuneka iphuculwe, kwaye imarike yasekhaya ecacileyo yangoku ixhomekeke kakhulu ekungenisweni kwamanye amazwe, ngoko kusekho indawo enkulu yokuphuhliswa kweemarike zasekhaya kwixesha elizayo.Ekugqibeleni, izinto eziphezulu eziphezulu ezifana ne-binary kunye ne-ternary copolymerization yefilimu ye-CPP kunye nombhobho wamanzi ashushu zikhawulelwe ekuboneleleni kweemarike ngenxa yamandla abo amancinci kunye nomsebenzi ophantsi.Unikezelo lwasekhaya lunokuthi luphendule kuphela malunga ne-50% yesabelo semarike, kwaye kusekho indawo enkulu yokudlala kwimarike yasekhaya.Ukushwankathela, izinga lokukhula kwexesha elizayo lokwandiswa komthamo wepolypropylene lingaphantsi koxinzelelo lwemarike jikelele yepolypropylene, kwaye imfuno yentengiso isenendawo enkulu yophuhliso, uyilo lwexesha elizayo lophando oluphezulu lwepolypropylene kunye nemveliso yophuhliso. kunyanzelekile.
