Amaxabiso asekhaya e-styrene aye enyuka kwaye emva koko ahlengahlengiswa abuyele kwindlela eguqukayo. Kwiveki ephelileyo, i-spot-high-end deal e-Jiangsu kwi-10,150 yuan / ton, isivumelwano esisezantsi kwi-9,750 yuan / ton, isiphelo esiphezulu nesisezantsi sokusasazeka kwi-400 yuan / ton. Amaxabiso e-oyile ekrwada alawula i-styrene, kwaye i-benzene ecocekileyo ihlala iqinile, kwixabiso leoli i-pullback, iphinde icinezelwe inzuzo ye-styrene, icala leendleko liyaqhubeka nokuxhasa, kwaye ekupheleni kweveki i-oyile ekrwada iphinda ibuyele ngelixa ilandela ukunyuka. Imfuno esezantsi yomlambo ibanzi, iziseko ziyaqhubeka, ubhubhane kunye neengeniso zemveliso phantsi kwempembelelo yeplanti yasekhaya esezantsi iqala kakubi, icala lokubonelela kunye nemfuno kunzima ukunyusa i-styrene.

Icala lonikezelo
Okwangoku, isityalo se-styrene sasekhaya siqala kwinqanaba eliphantsi, phantsi kweempembelelo zenzuzo yemveliso, izityalo ezininzi ezingadityanisiweyo zikwindawo yokupaka ukunciphisa okubi, inxalenye yesixhobo esidibeneyo okanye ukugcinwa, okanye ukuchithwa kwendawo yokupaka kunye nokunciphisa umthwalo, kuphela. ukwenza imveliso ayinyukanga. Ke ngoko, imveliso yasekhaya ye-styrene kunzima ukucinezela amaxabiso, nto leyo eyenza ukuba ukuguquguquka kwemveliso yale veki kungabonakali, ngelixa ukuncitshiswa kwamva nje kwe-negative Lihua Yi kwenza ukuveliswa kweveki ye-styrene kuncitshiswe kancinci. Imveliso ye-styrene yasekhaya iyonke iya kunyuka kwixesha elizayo njengoko imveliso yezinye iiyunithi iqala kwakhona.
Icala lemfuno
Imfuno esezantsi yomlambo ayizange itshintshe kakhulu kwixesha elizayo elikufutshane, i-EPS ngenxa yokunciphisa okungalunganga kwamva nje kwabanye abavelisi, imfuno ye-styrene yawa, kodwa imfuno yesityalo se-PS kunye ne-ABS yanda, ngoko ngokubanzi, ukuncitshiswa kwemfuno ezintathu ezisezantsi kuncinci kakhulu kwixesha elizayo elikufutshane. , kwaye kukho indawo yokuphucula imfuno emva kwexesha. Kuphela ubhubhani wangoku eMpuma China unempembelelo enkulu kwimfuno ye-styrene okanye iqondo elithile loxinzelelo.
Okwangoku, amaxabiso eoli aphinde anyuka ukuya kwinqanaba eliphezulu, enyuka kwakhona elinganiselwe; amaxabiso e-benzene acocekileyo ayaqhubeka eqina, kodwa imarike emfutshane enyanzeliswayo inokuhlala ixesha elide ixhalabile, ngakumbi ukuba ixabiso le-oyile libuyela umva, ibenzene ecocekileyo okanye ngokuhla; ngoko ke, nangona kukho inkxaso kwicala leendleko, kodwa ixabiso lokunokwenzeka kwe-pullback, inkxaso yeendleko kunye nokuhla. Icala lokubonelela kunye nemfuno yokugcina, icala lokubonelela, imveliso ye-styrene yefektri izinzile, kunye nokwanda okuncinci esixekweni; ngelixa icala imfuno, ubhubhane indawo Jiangsu iyaqhubeka, izityalo EPS ngamnye echatshazelwa yokupaka, PS ngenxa iingxaki inzuzo ezinye izityalo unenjongo yokupaka ukunciphisa umthwalo. Ke, kule veki, amaxabiso e-styrene asekhaya anqunyelwe, kwaye kunokubakho ukuhla, ixabiso lendawo kwimarike yeJiangsu kulindeleke ukuba libe phakathi kwe-9700-10000 yuan / ton.
