I. Uqikelelo lobonelelo ngemveliso – Umthamo omtsha

Kulindeleke ukuba kwisiqingatha sesibini sonyaka, umthamo wasekhaya wemveliso ye-styrene uya kugcina umkhwa okhulayo, izibalo ezirhabaxa zilindeleke kwisiqingatha sesibini sonyaka kuya kuba ne-1.8 yezigidi zeetoni / ngonyaka we-styrene amandla omatshini omtsha uya kwakhiwa kwaye xa kuqalwa ukusebenza, kulindeleke ukunyuka kwamandla nge-9.22%.

2. Uqikelelo lwemveliso kunye nokusetyenziswa kwamandla

Kwisiqingatha sesibini sonyaka, ukuveliswa kwe-styrene kuya kukhula malunga ne-8.09%, ngokukodwa ngenxa yemveliso elindelekileyo ye-1.8 yezigidi zeetoni ngonyaka, ezinye izixhobo ze-styrene ziya kuqalisa kwakhona, kwaye amashishini asezantsi aya kubuyiselwa ngokuyinxenye, kwaye ezinye izixhobo ezitsha ezisezantsi ziya kuba kwimarike, kwaye ulindele ukwanda kwemveliso ye-styrene. Nangona kunjalo, ukubonelela okulindelekileyo kukhulu kunokwenyuka kwemfuno, ngoko ukusetyenziswa kwamandla ngokubanzi kwesixhobo se-styrene kuya kuncipha, kwaye isiqalo sonke seprojekthi singaphantsi kwesiqingatha sokuqala sonyaka.

Okwesithathu, uqikelelo lwemfuno yabathengi

Idatha ibonisa ukuba kwisiqingatha sesibini se-2023, eyona nto isezantsi ye-styrene, ukuba isicwangciso esitsha sesityalo sinokusebenza ngokupheleleyo, kulindeleke ukuba umthamo we-PS kwisiqingatha sesibini sonyaka uya kunyuka ngeetoni ze-580,000 / ngonyaka. , amandla e-EPS kwisiqingatha sesibini sonyaka kulindeleke ukuba anyuke ngeetoni ze-170,000 / ngonyaka, kwaye amandla e-ABS kwisiqingatha sesibini sonyaka kulindeleke ukuba anyuke nge-1.56 yezigidi zeetoni / ngonyaka, kunye nemfuno ye-styrene kulindeleke ukuba inyuke malunga ne-1.8 yezigidi zeetoni ngokomlinganiselo wesondlo se-styrene. Kuyafana nokunyuka okulindelekileyo kwi-styrene. Nangona kunjalo, ngokutsho kwishedyuli yemveliso yommandla weendaba, kuya kubakho inani elikhulu lezixhobo ezisezantsi ezilibazisekileyo, kwaye kukho izixhobo zomntu ngamnye kunye nokusebenza okuthile okufana nokuguqulwa kwemveliso, ngokukodwa kwi-downstream kunye nemeko yesiqinisekiso sokunciphisa imveliso elindelekileyo, yinto. kulindeleke ukuba i-50% yomthamo omtsha unokufakwa kwimveliso okwethutyana, ngokutsho komyinge wokuqala wesiqingatha sokuqala seshishini, kulindeleke ukuba imfuno yayo ye-styrene iya kuba ngaphantsi kokunyuka kwe-styrene. Isiqingatha sesibini semarike ye-styrene ukubonelela ngempembelelo encedisayo.
