I. Isibikezelo sokuhlinzekwa kokukhiqiza - Umthamo omusha

Kulindeleke ukuthi engxenyeni yesibili yonyaka, amandla okukhiqiza ama-styrene asekhaya azogcina umkhuba okhulayo, izibalo ezinzima zilindeleke engxenyeni yesibili yonyaka kuzokwakhiwa amathani ayizigidi eziyi-1.8/ngonyaka wezitshalo ze-styrene ezintsha futhi uma iqala ukusebenza, kulindeleke ukuthi ikhule ngo-9.22%.

2. Isibikezelo sokuphuma kanye nokusetshenziswa kwamandla

Engxenyeni yesibili yonyaka, ukukhiqizwa kwe-styrene kuzokhula cishe ku-8.09%, ikakhulukazi ngenxa yokukhiqizwa okulindelekile kwamathani ayizigidi ezingu-1.8 ngonyaka, amanye amadivaysi e-styrene azoqala kabusha, futhi amabhizinisi aphansi azobuyiselwa kancane, kanti amanye amadivaysi amasha angaphansi komfula nawo azoba semakethe, futhi alindele ukwanda kokuphuma kwe-styrene. Kodwa-ke, ukunikezwa okulindelekile kukhulu kunokwenyuka kwesidingo, ngakho ukusetshenziswa kwamandla sekukonke kwedivayisi ye-styrene kuzokwehla, futhi isiqalo sonke sephrojekthi singaphansi kwengxenye yokuqala yonyaka.

Okwesithathu, isibikezelo sesidingo sabathengi

Idatha ibonisa ukuthi engxenyeni yesibili ye-2023, umfula oyinhloko we-styrene, uma uhlelo olusha lwesitshalo lungasebenza ngokugcwele, kulindeleke ukuthi umthamo we-PS engxenyeni yesibili yonyaka uzokhula ngamathani angu-580,000 / ngonyaka. , umthamo we-EPS engxenyeni yesibili yonyaka kulindeleke ukuthi yenyuke ngamathani angu-170,000/ngonyaka, futhi umthamo we-ABS engxenyeni yesibili yonyaka kulindeleke ukuthi yenyuke ngamathani ayizigidi ezingu-1.56/ngonyaka, kanye nesidingo se-styrene kulindeleke ukuthi inyuke cishe ngamathani ayizigidi eziyi-1.8 ngokwesilinganiso sokuphakelwa kwe-styrene. Kuyafana nokukhuphuka okulindelekile kwe-styrene. Kodwa-ke, ngokuya ngeshejuli yokukhiqiza yendawo yezindaba, kuzoba nenani elikhulu lamadivayisi abambezelekayo, futhi kukhona amadivayisi angawodwana anokusebenza okuthile okufana nokuguqulwa komkhiqizo, ikakhulukazi lapho kwehla khona umfula onesimo sesiqinisekiso sokunciphisa ukukhiqizwa esilindelwe. kulindeleke ukuthi u-50% womthamo omusha ungafakwa ekukhiqizweni okwesikhashana, ngokwesilinganiso sokuqala sengxenye yokuqala yebhizinisi, kulindeleke ukuthi isidingo sayo se-styrene sibe ngaphansi kunokwenyuka kokuhlinzekwa kwe-styrene. Ingxenye yesibili yemakethe ye-styrene ukunikeza umthelela othile osizayo.
