Ekuqaleni kukaJulayi, ityhefu kunye ne-chain yayo yemizi-mveliso iphele phantse iiyure ezintathu zenyanga ezintathu kwaye yaphinda yadandaza ngokukhawuleza kwaye igorha ngokuchasene nomkhwa. Imakethi yaqhubeka inyuka ngo-Agasti, ngamaxabiso aphezulu emanzi afikelela kwinqanaba labo eliphezulu ukusukela ekuqaleni kuka-Okthobha 2022. Nangona kunjalo, izinga lokukhula kweemveliso eziphantsi liphantsi kakhulu, kunye ne Imbonakalo ephezulu yentengiso inomda.
Ukunyuka kweendleko ze-trugger kwi-spimbacks kwiNzuzo yeShishini
Ukunyuka okuqinileyo kwamaxabiso ezinto ezinqabileyo kukhokelele ekususeni kancinci koxinzelelo lweendleko, ukunciphisa ingeniso ye-styrene kunye ne-chain yeshishini eliphantsi. Uxinzelelo lwelahleko kumashishini e-styrene kunye namashishini e-PS anyukile, kwaye amashishini nemizi-mveliso ye-ABS atshintshe kwinzuzo kwilahleko. Ukubeka iliso kubonisa ukuba okwangoku, kwi-chain yeshishini iyonke, ngaphandle komzi mveliso we-EPS, oguqula zombini ilahleko ye-Breatven, iXesha leMveliso yeMveliso enamanye amashishini lisephezulu. Ngokuziqalisa ngokuthe ngcembe amandla okutsha kwemveliso, iimfuno zoncedo eziphikisana nemveliso ye-PS kunye ne-ABS ivele. Ngo-Agasti, ubonelelo ngo-ABS lwalunele, kwaye uxinzelelo lwelahleko lweshishini lunyukile; Ukwehla kwe-PS kunikezelo kukhokelele ekunciphiseni kancinci uxinzelelo lokulahleka kwecandelo ngo-Agasti.
Ukudityaniswa kwee-odolo ezingapheliyo kunye noxinzelelo lwelahleko kukhokelele ekunciphiseni kwemithwalo eminye yemigangatho
Idatha ibonisa ukuba kuthelekiswa nexesha elifanayo ngo-2022, umthwalo wokusebenza ophakathi we-EPS kunye namashishini e-PS ubonakalise imeko esezantsi. Ichatshazelwe luxinzelelo lwelahleko yemveliso, inzondelelo yamashishini emveliso ukuqala imisebenzi iye yabuthathaka. Ukwenzela ukuthintela ingozi yelahleko, banciphisile umthwalo wabo omnye emva kwenye; Ulondolozo olucwangcisiweyo kunye olungacwangciswanga lujolise phambili ngoJuni ukuya ku-Agasti. Njengoko iinkampani zesondlo ziyaqhubeka nokuvelisa, umthwalo wokusebenza womzi-mveliso weStyrene wanyuka kancinane ngo-Agasti; Ngokomzi-mveliso we-ABS, ukuphela kolondolozo lwamaxesha onyaka kunye nokhuphiswano lwe-tierce luye lwakhokelela kwimeko ephezulu kwinqanaba lokusebenza kweshishini ngo-Agasti.
Ukujonga phambili: Iindleko eziphezulu kwixesha eliphakathi, amaxabiso entengiso aphantsi koxinzelelo, kunye ne-chain yenzuzo ye-SIFICS
Kwixesha eliphakathi, ioyile yamanye amazwe iyaqhubeka iqhubela phambili, kwaye ubonelelo lwe-Benzene olunyulu luqinile, kwaye kulindeleke ukuba uhlale uguqukile. Imakethi ye-styrene kwezi zinto zintathu ziphezulu zinokugcina ukuzinza okuphezulu. Icala lokuhanjiswa kwamashishini amathathu aphambili liphantsi koxinzelelo ngenxa yokuphehlelelwa kweeprojekthi ezintsha, kodwa izinga lokukhula kwemfuno licotha, ngenxa yokunyuka kwamaxabiso anqongopheleyo.
Ngokwexabiso, amaxabiso eoyile etyhefu kunye ne-bedzene emsulwa inokuchaphazeleka ngenxa yokomeleza idola yaseMelika, kwaye inokujongana noxinzelelo olusezantsi kwixesha elifutshane. Kodwa ekuhambeni kwexesha, amaxabiso anokuhlala eguquka kwaye womelele. Umthamo wokuvelisa uyakhula ngokuthe ngcembe, kwaye ubonelelo lwe-Benzene elinyulu lunokuqina, ngaloo ndlela uqhuba amaxabiso entengiso ukugcina ulwando. Nangona kunjalo, imfuno ye-terminall engapheliyo inokunciphisa umda wexabiso lentengiso. Ngexesha elifutshane, amaxabiso e-styrene anokuguquguquka kumanqanaba aphezulu, kodwa njengoko iinkampani zesondlo ngokuthe ngcembe ziqala ukuvelisa, imakethi inokujongana nokulindelwe.
