Kwiminyaka yakutshanje, imboni ye-polypropylene iqhubekile nokwandisa amandla ayo, kwaye isiseko sayo sokuvelisa siye sakhula ngokufanelekileyo;Nangona kunjalo, ngenxa yokunciphisa ukukhula kweemfuno ezisezantsi kunye nezinye izinto, kukho uxinzelelo olubalulekileyo kwicala lokubonelela nge-polypropylene, kwaye ukhuphiswano ngaphakathi kwishishini luyabonakala.Amashishini asekhaya ahlala enciphisa imveliso kunye nokuvalwa komsebenzi, okukhokelela ekunciphiseni komthwalo wokusebenza kunye nokwehla kokusetyenziswa kwamandla okuvelisa i-polypropylene.Kulindeleke ukuba izinga lokusetyenziswa komthamo wokuvelisa i-polypropylene liya kudlula kwimbali ephantsi ngo-2027, kodwa kusenzima ukunciphisa uxinzelelo lokubonelela.
Ukususela kwi-2014 ukuya kwi-2023, amandla okuvelisa i-polypropylene yasekhaya iye yanda kakhulu, iqhuba ukunyuka konyaka kwimveliso ye-polypropylene.Ngo-2023, izinga lokukhula kwekhompawundi lifikelele kwi-10.35%, ngelixa ngo-2021, izinga lokukhula kwemveliso ye-polypropylene lafikelela kwinqanaba elitsha malunga ne-10 iminyaka.Ngokombono wophuhliso lweshishini, ukususela ngo-2014, eqhutywa yimigaqo-nkqubo yeekhemikhali zamalahle, amandla okuvelisa amalahle kwi-polyolefins aye akhula ngokuqhubekayo, kwaye imveliso ye-polypropylene yasekhaya iye yanda unyaka nonyaka.Ngo-2023, imveliso yasekhaya ye-polypropylene ifikelele kwi-32.34 yezigidi zeetoni.
Kwixesha elizayo, kusekho umthamo omtsha wemveliso okhululwe kwi-polypropylene yasekhaya, kwaye imveliso iya kwanda ngokufanelekileyo.Ngokoqikelelo lukaJin Lianchuang, inyanga kwizinga lokukhula kwenyanga yemveliso yepolypropylene ngo-2025 imalunga ne-15%.Kulindeleke ukuba ngo-2027, imveliso ye-polypropylene yasekhaya iya kufikelela malunga ne-46.66 yezigidi zeetoni.Nangona kunjalo, ukusuka kwi-2025 ukuya kwi-2027, izinga lokukhula kwemveliso ye-polypropylene liye lancipha unyaka nonyaka.Kwelinye icala, kukho ukulibaziseka okuninzi kwizixhobo zokwandisa umthamo, kwaye kwelinye icala, njengoko uxinzelelo lonikezelo luba lubala ngakumbi kwaye ukhuphiswano lulonke kushishino lukhula ngokuthe ngcembe, amashishini aya kunciphisa imisebenzi engalunganga okanye anyuse indawo yokupaka ukunciphisa uxinzelelo lwexeshana.Kwangaxeshanye, oku kukwabonakalisa imeko ekhoyo ngoku yemfuno ecothayo yemalike kunye nokukhula kwamandla okukhawulezayo.
Ukusuka kumbono wokusetyenziswa kwamandla, kumxholo wenzuzo yonke elungileyo, amashishini emveliso anezinga eliphezulu lokusetyenziswa kwamandla ukusuka kwi-2014 ukuya kwi-2021, kunye nesantya sokusetyenziswa kwamandla asisiseko ngaphezu kwe-84%, ngakumbi ukufikelela kwincopho ye-87.65% ngo-2021. I-2021, phantsi koxinzelelo olubini lweendleko kunye nemfuno, izinga lokusetyenziswa kwe-polypropylene umthamo wemveliso liye lancipha, kwaye ngo-2023, izinga lokusetyenziswa kwamandla okuvelisa liye lancipha ukuya kwi-81%.Kwinqanaba lamva, kukho iiprojekthi ezininzi zasekhaya zepolypropylene ezicetywayo ukuba zisetyenziswe, ngoko ke imarike iya kucinezelwa kukubonelela okuphezulu kunye neendleko eziphezulu.Ukongeza, ubunzima bokungonelanga kwee-odolo ezisezantsi, i-inventory eqokelelweyo yemveliso egqityiweyo, kunye nokuncipha kweenzuzo ze-polypropylene zivela ngokuthe ngcembe.Ke ngoko, amashishini emveliso nawo aya kuthatha inyathelo lokuqala lokunciphisa umthwalo okanye athathe ithuba lokuvala ukugcinwa.Ukusuka kwimbono yamalahle ukuya kwi-polypropylene, okwangoku, uninzi lwamalahle e-China ukuya kwiimveliso ze-polypropylene zizinto ezikumgangatho ophantsi-injongo jikelele kunye nezinye izixhobo ezikhethekileyo zomgangatho ophakathi, kunye neemveliso ezikumgangatho ophezulu kakhulu ezithunyelwa ngaphandle.Amashishini kufuneka aqhubeke eguqula kwaye ephucula, ngokuthe ngcembe atshintshe ukusuka kwixabiso eliphantsi kunye neemveliso ezongeziweyo zexabiso eliphantsi ukuya kwimveliso ephezulu, ukuze kwandiswe ukhuphiswano lwemarike.
