Kwiminyaka yakutshanje, ngokukhula okuqhubekayo komthamo wemveliso kwishishini lepolypropylene yasekhaya, ukuveliswa kwepolypropylene kuye kwanda unyaka nonyaka. Ngenxa yokunyuka kwemfuno yeemoto, izixhobo zasekhaya, umbane, kunye neepalethi, ukuveliswa kwepolymer polypropylene enganyangekiyo ikhula ngokukhawuleza. Imveliso elindelekileyo yee-copolymers ezixhathisayo ngo-2023 yi-7.5355 yezigidi zeetoni, ukwanda kwe-16.52% xa kuthelekiswa nonyaka ophelileyo (iitoni zezigidi ezi-6.467). Ngokukodwa, ngokubhekiselele kulwahlulo, ukuveliswa kwee-copolymers ezinyibilikayo eziphantsi kukhulu kakhulu, kunye nemveliso elindelekileyo malunga ne-4.17 yezigidi zeetoni ngo-2023, ibala i-55% yexabiso lilonke leempembelelo ze-copolymers. Umlinganiselo wemveliso yokunyibilika okuphezulu okuphakathi kunye nee-copolymers ezixhathisa impembelelo ziyaqhubeka zikhula, zifikelela kwi-1.25 kunye ne-2.12 yezigidi zeetoni ngo-2023, zibalelwa kwi-17% kunye ne-28% yetotali.
Ngokwexabiso, ngo-2023, intsingiselo iyonke yokumelana ne-copolymer polypropylene yaqala ukwehla kwaye emva koko yenyuka, kulandelwa kukwehla okubuthathaka. Umahluko wexabiso phakathi kwe-co polymerization kunye nomzobo wocingo unyaka wonke uphakathi kwe-100-650 yuan/ton. Kwikota yesibini, ngenxa yokukhutshwa kancinci kwemveliso kumaziko amatsha emveliso, kudityaniswa nexesha elingekhoyo lemfuno, amashishini emveliso yesiphelo ayenemiyalelo ebuthathaka kwaye ukuzithemba kukonke kwakunganelanga, okubangele ukuhla ngokubanzi kwemarike. Ngenxa yokunyuka okuphawulekayo kweemveliso ze-homopolymer eziziswa sisixhobo esitsha, ukhuphiswano lwamaxabiso lunzima, kwaye ukuhla komzobo oqhelekileyo wocingo kuyanda. Xa sithetha ngokuthelekisekayo, impembelelo ye-copolymerization exhathisayo ibonise ukuxhathisa okuqinileyo ekuweni, kunye nomahluko wexabiso phakathi kwe-copolymerization kunye nomzobo wocingo ukwandisa ukuya kwi-650 ye-yuan/toni. Kwikota yesithathu, ngenkxaso eqhubekayo yomgaqo-nkqubo kunye nenkxaso yeendleko ezinamandla, izinto ezininzi ezithandekayo ziqhubele phambili ukuphindaphinda kwamaxabiso ePP. Njengoko ukunikezelwa kwee-anti-collision copolymers kwanda, ukunyuka kwexabiso leemveliso ze-copolymer kwancipha kancinci, kwaye umahluko wexabiso lomzobo we-copolymer ubuyele kwisiqhelo.
Ixabiso eliphambili leplastiki esetyenziswa kwiimoto yiPP, ilandelwa zezinye izinto zeplastiki ezifana ne-ABS kunye ne-PE. Ngokwesebe elichaphazelekayo lemizi-mveliso ye-Automobile Industry Association, ukusetyenziswa kweplastiki kwi-sedan yezoqoqosho nganye e-China malunga ne-50-60kg, iilori ezinzima zinokufikelela kwi-80kg, kwaye ukusetyenziswa kweplastiki kwi-sedan ephakathi kunye ne-high-end e-China yi-100- 130kg. Ukusetyenziswa kweemoto kuye kwaba yinto ebalulekileyo ezantsi kwempembelelo yepolymer polypropylene, kwaye kule minyaka mibini idlulileyo, ukuveliswa kweemoto kuye kwaqhubeka nokukhula, ngakumbi ngokunyuka okubonakalayo kwizithuthi zamandla amatsha. Ukususela ngoJanuwari ukuya ku-Oktobha 2023, ukuveliswa kunye nokuthengiswa kweemoto kufikelele kwi-24.016 yezigidi kunye ne-23.967 yezigidi ngokulandelanayo, ukunyuka kwe-8% kunye ne-9.1% ngonyaka. Kwixesha elizayo, kunye nokuqokelela okuqhubekayo kunye nokubonakaliswa kwemiphumo yomgaqo-nkqubo wokukhula koqoqosho oluzinzile kwilizwe, kunye nokuqhubeka kwenkxaso-mali yokuthenga imoto yasekhaya, imisebenzi yokukhuthaza kunye namanye amanyathelo, kulindeleke ukuba imboni yemoto iya kwenza kakuhle. Kulindeleke ukuba ukusetyenziswa kwee-copolymers ezixhathisayo kwishishini leemoto nako kuya kuba nkulu kwixesha elizayo.
