Kwiminyaka yakutshanje, ngokukhula okuqhubekayo kwamandla emveliso kwishishini le-polypropylene yasekhaya, imveliso ye-polypropylene ibikhula minyaka le. Ngenxa yokwanda kwemfuno yeemoto, izixhobo zasekhaya, umbane, kunye neepallet, imveliso ye-polypropylene ye-copolymer enganyangekiyo ikhula ngokukhawuleza. Imveliso elindelekileyo ye-copolymers enganyangekiyo ngo-2023 yi-7.5355 yezigidi zeetoni, ukwanda kwe-16.52% xa kuthelekiswa nonyaka ophelileyo (iitoni ezizigidi ezi-6.467). Ngokukodwa, ngokwecandelo, imveliso ye-low melt copolymers inkulu kakhulu, kunye nemveliso elindelekileyo ye-4.17 yezigidi zeetoni ngo-2023, ebalelwa kwi-55% yenani lilonke lee-copolymers ezinganyangekiyo. Umlinganiselo wemveliso ye-medium high melting kunye ne-impact resistant copolymers uyaqhubeka nokwanda, ufikelela kwi-1.25 yezigidi zeetoni ngo-2023, ebalelwa kwi-17% kunye ne-28% iyonke.
Ngokuphathelele amaxabiso, ngo-2023, umkhwa opheleleyo we-polypropylene ye-copolymer enganyangekiyo yayiqala ukwehla yaze yanyuka, yalandelwa kukwehla okubuthathaka. Umahluko wamaxabiso phakathi kwe-copolymerization kunye nomzobo wentambo unyaka wonke uphakathi kwe-100-650 yuan/ton. Kwikota yesibini, ngenxa yokukhululwa kancinci kwemveliso kwiindawo ezintsha zemveliso, kunye nemfuno yexesha elingaphandle kwexesha, amashishini emveliso yesiphelo ayenee-odolo ezibuthathaka kwaye ukuzithemba kokuthengwa kwakunganelanga, nto leyo ebangele ukwehla okukhulu kwimarike. Ngenxa yokwanda okukhulu kweemveliso ze-homopolymer ezibangelwe sisixhobo esitsha, ukhuphiswano lwamaxabiso lunamandla, kwaye ukwehla komzobo wentambo eqhelekileyo kuyanda. Ngokuthe ngqo, i-copolymerization enganyangekiyo ibonakalise ukumelana okunamandla nokuwa, kunye nomahluko wamaxabiso phakathi kwe-copolymerization kunye nomzobo wentambo ukhula ukuya kwi-650 yuan/ton. Kwikota yesithathu, ngenkxaso eqhubekayo yomgaqo-nkqubo kunye nenkxaso enamandla yeendleko, izinto ezininzi ezilungileyo ziqhubele phambili amaxabiso e-PP. Njengoko ukuhanjiswa kwee-copolymers ezichasene nokungqubana kwanda, ukunyuka kwamaxabiso eemveliso ze-copolymer kuye kwehla kancinci, kwaye umahluko wamaxabiso ekutsalweni kwe-copolymer wabuyela kwisiqhelo.
Isixa esiphambili seplastiki esetyenziswa kwiimoto yiPP, ilandelwe zezinye izinto zeplastiki ezifana ne-ABS kunye ne-PE. Ngokutsho kwesebe elifanelekileyo lemizi-mveliso le-Automobile Industry Association, ukusetyenziswa kweplastiki nge-sedan e-economy eTshayina malunga ne-50-60kg, iilori ezinzima zinokufikelela kwi-80kg, kwaye ukusetyenziswa kweplastiki nge-sedan ephakathi nephezulu eTshayina yi-100-130kg. Ukusetyenziswa kweemoto kube yinto ebalulekileyo esezantsi kwe-copolymer polypropylene engashukumiyo, kwaye kwiminyaka emibini edlulileyo, imveliso yeemoto iqhubekile nokukhula, ngakumbi ngokwanda okubonakalayo kwezithuthi ezintsha zamandla. Ukususela ngoJanuwari ukuya ku-Okthobha ka-2023, imveliso kunye nokuthengiswa kweemoto kufikelele kwi-24.016 yezigidi kunye ne-23.967 yezigidi ngokulandelanayo, ukunyuka kwe-8% kunye ne-9.1% unyaka nonyaka. Kwixesha elizayo, ngokuqokelelwa okuqhubekayo kunye nokubonakaliswa kweziphumo zomgaqo-nkqubo zokukhula koqoqosho oluzinzileyo kweli lizwe, kunye nokuqhubeka kwezibonelelo zokuthengwa kweemoto zasekuhlaleni, imisebenzi yokukhuthaza kunye nezinye iindlela, kulindeleke ukuba ishishini leemoto lisebenze kakuhle. Kulindeleke ukuba ukusetyenziswa kwee-copolymers ezichasayo impembelelo kwishishini leemoto kuya kuba luncedo kakhulu kwixesha elizayo.
