I. Uqikelelo lwemveliso – Amandla amatsha

Kulindeleke ukuba kwisiqingatha sesibini sonyaka, amandla okuvelisa i-styrene yasekhaya aza kuhlala ekhula, kulindeleke ukuba izibalo ezingeyonyani kwisiqingatha sesibini sonyaka kuza kwakhiwa kwaye kusetyenziswe iitoni ezili-1.8 lezigidi ngonyaka, amandla okuvelisa i-styrene entsha aza kwakhiwa aze aqalise ukusebenza, kwaye amandla okuvelisa alindeleke ukuba anyuke nge-9.22%.

2. Uqikelelo lwemveliso kunye nokusetyenziswa komthamo

Kwisiqingatha sesibini sonyaka, imveliso ye-styrene iya kukhula malunga ne-8.09%, ikakhulu ngenxa yemveliso elindelekileyo yeetoni ezili-1.8 lezigidi ngonyaka, ezinye izixhobo ze-styrene ziya kuqalisa kwakhona, kwaye amashishini asezantsi aya kubuyiselwa kancinci, kwaye ezinye zezixhobo ezitsha ezisezantsi ziya kubakho kwimarike, kwaye zilindele ukwanda kwemveliso ye-styrene. Nangona kunjalo, unikezelo olulindelekileyo lukhulu kunokwanda kwemfuno, ngoko ke ukusetyenziswa kwamandla esixhobo se-styrene kuya kuncipha, kwaye ukuqala kweprojekthi iyonke kungaphantsi kwesiqingatha sokuqala sonyaka.

Okwesithathu, uqikelelo lwemfuno yabathengi

Idatha ibonisa ukuba kwisiqingatha sesibini sowama-2023, eyona ndawo iphambili ye-styrene, ukuba isicwangciso esitsha sesityalo sinokusebenza ngokupheleleyo, kulindeleke ukuba amandla e-PS kwisiqingatha sesibini sonyaka anyuke ngeetoni ezingama-580,000 ngonyaka, amandla e-EPS kwisiqingatha sesibini sonyaka kulindeleke ukuba anyuke ngeetoni ezili-170,000 ngonyaka, kwaye amandla e-ABS kwisiqingatha sesibini sonyaka kulindeleke ukuba anyuke ngeetoni ezili-1.56 zezigidi ngonyaka, kwaye imfuno ye-styrene kulindeleke ukuba inyuke ngeetoni ezimalunga ne-1.8 yezigidi ngokwe-styrene feed ratio. Kuyafana nokunyuka okulindelekileyo kwe-styrene. Nangona kunjalo, ngokweshedyuli yemveliso yomphezulu weendaba, kuya kubakho inani elikhulu lezixhobo ezisezantsi ziya kulibaziseka, kwaye kukho izixhobo ngazinye ezinentsebenzo ethile efana nokuguqulwa kwemveliso, ingakumbi kwimeko esezantsi enesiqinisekiso sokunciphisa imveliso elindelekileyo, kulindeleke ukuba i-50% yamandla amatsha afakwe kwimveliso okwethutyana, ngokwesiqalo esiphakathi sesiqingatha sokuqala seshishini, kulindeleke ukuba imfuno yayo ye-styrene ibe ngaphantsi kunokwanda kobonelelo lwe-styrene. Isiqingatha sesibini semarike ye-styrene sibonelela ngempembelelo ethile encedisayo.
