Kwiminyaka yakutshanje, ishishini le-polypropylene liqhubekile nokwandisa amandla alo, kwaye isiseko salo semveliso sikhula ngokufanelekileyo; Nangona kunjalo, ngenxa yokucotha kokukhula kwemfuno kunye nezinye izinto, kukho uxinzelelo olukhulu kwicala lokubonelela nge-polypropylene, kwaye ukhuphiswano ngaphakathi kushishino luyabonakala. Amashishini asekhaya ahlala enciphisa imisebenzi yemveliso kunye nokuvalwa, okubangela ukwehla komthwalo wokusebenza kunye nokwehla kokusetyenziswa kwamandla emveliso ye-polypropylene. Kulindeleke ukuba izinga lokusetyenziswa kwamandla emveliso ye-polypropylene lidlule kwinqanaba eliphantsi kwimbali ngo-2027, kodwa kusenzima ukunciphisa uxinzelelo lokubonelela.
Ukususela ngo-2014 ukuya ku-2023, amandla okuvelisa i-polypropylene yasekhaya anyuke kakhulu, nto leyo eqhubela phambili ukwanda kwemveliso ye-polypropylene minyaka le. Ngo-2023, izinga lokukhula kwe-compound lifikelele kwi-10.35%, ngelixa ngo-2021, izinga lokukhula kwemveliso ye-polypropylene lifikelele kwinqanaba eliphezulu kwiminyaka ephantse ibe li-10. Ngokwembono yophuhliso lweshishini, ukusukela ngo-2014, eqhutywa yimigaqo-nkqubo yeekhemikhali zamalahle, amandla okuvelisa amalahle ukuya kwi-polyolefins ebekhula ngokuqhubekayo, kwaye imveliso ye-polypropylene yasekhaya ibisanda minyaka le. Ngo-2023, imveliso ye-polypropylene yasekhaya ifikelele kwi-32.34 yezigidi zeetoni.
Kwixesha elizayo, kuya kubakho amandla amatsha okuvelisa i-polypropylene yasekhaya, kwaye nemveliso nayo iya kwanda ngokufanelekileyo. Ngokutsho koqikelelo lukaJin Lianchuang, izinga lokukhula kwemveliso ye-polypropylene ngenyanga ngo-2025 limalunga ne-15%. Kulindeleke ukuba ngo-2027, imveliso ye-polypropylene yasekhaya iya kufikelela kwiitoni ezingama-46.66 ezigidi. Nangona kunjalo, ukususela ngo-2025 ukuya ku-2027, izinga lokukhula kwemveliso ye-polypropylene liye lehla unyaka nonyaka. Kwelinye icala, kukho ukulibaziseka okuninzi kwizixhobo zokwandisa amandla, kwaye kwelinye icala, njengoko uxinzelelo lokubonelela luba lubonakala ngakumbi kwaye ukhuphiswano lulonke kushishino lukhula kancinci kancinci, amashishini aya kunciphisa imisebenzi engalunganga okanye andise indawo yokupaka ukuze kuncitshiswe uxinzelelo lwexeshana. Kwangaxeshanye, oku kukwabonisa imeko yangoku yemfuno ecothayo yemarike kunye nokukhula ngokukhawuleza kwamandla.
Ngokwembono yokusetyenziswa kwamandla, kwimeko yenzuzo entle iyonke, amashishini emveliso ayenezinga eliphezulu lokusetyenziswa kwamandla ukusukela ngo-2014 ukuya ku-2021, kunye nezinga elisisiseko lokusetyenziswa kwamandla elingaphezulu kwe-84%, ngakumbi lifikelela kwincopho ye-87.65% ngo-2021. Emva ko-2021, phantsi koxinzelelo oluphindwe kabini lweendleko kunye nemfuno, izinga lokusetyenziswa kwamandla emveliso ye-polypropylene liye lehla, kwaye ngo-2023, izinga lokusetyenziswa kwamandla emveliso liye lehla laya kwi-81%. Kwinqanaba lokugqibela, kukho iiprojekthi ezininzi ze-polypropylene zasekhaya ezicwangciselwe ukuqaliswa ukusebenza, ngoko ke imakethi iya kucinezelwa kukunikezelwa okuphezulu kunye neendleko eziphezulu. Ukongeza, ubunzima bokunganeli kwee-odolo ezisezantsi, uluhlu lwemveliso egqityiweyo eqokelelweyo, kunye nenzuzo ehlayo ye-polypropylene ziyavela kancinci kancinci. Ke ngoko, amashishini emveliso aya kuthatha inyathelo lokunciphisa umthwalo okanye athathe ithuba lokuvala ukuze kulungiswe. Ngokwembono yamalahle ukuya kwi-polypropylene, okwangoku, uninzi lweemveliso zamalahle ukuya kwi-polypropylene zaseTshayina zizixhobo ezisetyenziswa kakhulu kwaye ezinye zizixhobo ezikhethekileyo eziphakathi, kwaye ezinye iimveliso eziphezulu zingeniswa kakhulu kwamanye amazwe. Amashishini kufuneka atshintshe kwaye aphucule rhoqo, etshintsha kancinci kancinci ukusuka kwiimveliso ezikumgangatho ophantsi nezinexabiso eliphantsi ukuya kwiimveliso eziphezulu, ukuze kuphuculwe ukhuphiswano lwemarike.
