Korodhka weyn ee wax-soo-saarka korantada sare ee gudaha iyo hoos u dhigida farqiga qiimaha tooska ah

Laga soo bilaabo 2020, dhirta polyetylen-ka gudaha waxay galeen wareegga balaadhinta dhexe, iyo awoodda wax-soo-saarka sanadlaha ah ee PE gudaha ayaa si degdeg ah u kordhay, iyada oo celcelis ahaan heerka kobaca sanadlaha ah ee ka sarreeya 10%. Wax-soo-saarka polyetylen-ka gudaha dalka laga soo saaro ayaa si degdeg ah u kordhay, iyada oo isku-xidhnaanta badeecada daran iyo tartan adag oo ka jira suuqa polyetylen. Inkasta oo baahida loo qabo polyetylen ay sidoo kale muujisay isbeddel korriin sannadihii la soo dhaafay, kobaca dalabku ma ahayn mid degdeg ah sida heerka kobaca saadka. Laga soo bilaabo 2017 ilaa 2020, awoodda wax-soo-saarka cusub ee polyetylen-ka gudaha inta badan waxay diiradda saartaa noocyada hoose ee korantada iyo kuwa toosan, mana jirin qalab koronto-sare ah oo laga hirgeliyay Shiinaha, taasoo keentay waxqabad xooggan oo ku saabsan suuqa-korontada sare. 2020, iyadoo farqiga qiimaha u dhexeeya LDPE iyo LLDPE uu si tartiib tartiib ah u kordhay, dareenka alaabada LDPE ayaa kordhay. Unugga wax soo saarka ee EVA co iyo Zhejiang Petrochemical LDPE ayaa la hawlgaliyey 2022, iyada oo awood wax-soo-saar sare oo gudaha ah oo 3.335 milyan tan ah maalintii hore.

2023, suuqa cadaadiska sare wuxuu muujiyay isbeddel iyo hoos u dhac. Qaadashada suuqa Waqooyiga Shiinaha tusaale ahaan, celceliska qiimaha cadaadiska sarreeya ee Jannaayo ilaa Maajo wuxuu ahaa 8853 yuan / ton, hoos u dhac weyn oo sanadle ah oo ah 24.24%. Xilligii ugu sarreeyay ee baahida loo qabo aflaanta caaga ah ee rubuci hore, qiimaha toosan ayaa ahaa mid xooggan. Celceliska qiimaha tooska ah ee Janaayo ilaa Abriil wuxuu ahaa 8273, hoos u dhac sanadle ah oo ah 7.42%. Farqiga qiimaha u dhexeeya danab sare iyo toosan ayaa si weyn loo soo koobay. Laga bilaabo Maajo 23-keedii, wadarta tooska ah ee gudaha suuqa Waqooyiga Shiinaha waxa ay ahayd 7700-7950 yuan/ton, halka cadaadiska sare ee gudaha ee filimka caadiga ah laga soo sheegay 8000-8200 yuan/ton. Farqiga qiimaha u dhexeeya danab sare iyo toosan wuxuu ahaa 250-300 yuan/ton.

Guud ahaan, iyada oo si joogto ah loo ballaarinayo awoodda wax-soo-saarka polyetylen-ka gudaha iyo kor u kaca tartiib-tartiibka ah ee sahayda gudaha, dhibaatada ka-soo-baxa ee warshadaha polyetylen-ka ayaa sii kordhay. Inkasta oo qiimaha wax soo saarka ee danab sare uu wax yar ka badan yahay linear, sababtoo ah beddelka linear iyo metallocene ee meelaha wax soo saarka qaarkood, waa adag tahay in la taageero qiimaha sare iyo faa'iido sare ee suuqa polyetylen hadda daciif ah, iyo farqiga qiimaha u dhexeeya danab sare iyo linear ayaa si weyn hoos ugu dhacay.
