Koror weyn oo ku yimid wax soo saarka danabka sare ee gudaha iyo ciriiriga farqiga qiimaha toosan

Tan iyo 2020, warshadaha polyetylen-ka ee gudaha ayaa galay wareeg ballaaran oo dhexe, awoodda wax soo saarka sanadlaha ah ee PE-da gudaha ayaa si degdeg ah u korodhay, iyadoo celcelis ahaan heerka kobaca sanadlaha ah uu ka badan yahay 10%. Soo saarista polyetylen-ka gudaha laga soo saaro ayaa si degdeg ah u korodhay, iyadoo la isku daray badeecadaha iyo tartanka xooggan ee suuqa polyetylen-ka. Inkasta oo baahida loo qabo polyetylen-ku ay sidoo kale muujisay isbeddel koboc sannadihii ugu dambeeyay, kobaca baahida ma uusan ahayn mid degdeg ah sida heerka kobaca saadka. Laga bilaabo 2017 ilaa 2020, awoodda wax soo saarka cusub ee polyetylen-ka gudaha ayaa inta badan diiradda saartay noocyada danab hooseeya iyo kuwa toosan, mana jirin qalab danab sare leh oo laga howlgaliyay Shiinaha, taasoo keentay waxqabad xooggan oo suuqa danab sare leh. Sannadkii 2020, markii farqiga qiimaha ee u dhexeeya LDPE iyo LLDPE uu si tartiib tartiib ah u ballaartay, dareenka alaabada LDPE ayaa kordhay. Qaybta wax soo saarka ee EVA iyo cutubka LDPE-da ee Zhejiang ayaa la hawlgeliyay 2022, iyadoo awood wax soo saar cadaadis sare leh oo gudaha ah ay tahay 3.335 milyan oo tan maalintii hore.

Sannadkii 2023, suuqa cadaadiska sare wuxuu muujiyay isbeddel isbeddelaya oo hoos u dhacaya. Marka la soo qaado suuqa Waqooyiga Shiinaha tusaale ahaan, celceliska qiimaha cadaadiska sare laga bilaabo Janaayo ilaa Maajo wuxuu ahaa 8853 yuan/ton, hoos u dhac weyn oo sanad-sannadeed ah oo ah 24.24%. Xilligii ugu sarreeyay ee baahida filimada balaastikada ah ee rubuci hore, qiimaha toosan wuxuu ahaa mid xooggan. Celceliska qiimaha toosan laga bilaabo Janaayo ilaa Abriil wuxuu ahaa 8273, hoos u dhac sanad-sannadeed ah oo ah 7.42%. Farqiga qiimaha u dhexeeya danabka sare iyo kuwa toosan ayaa si weyn loo yareeyay. Laga bilaabo Maajo 23, kan caadiga ah ee gudaha ee suuqa Waqooyiga Shiinaha wuxuu ahaa 7700-7950 yuan/ton, halka kan caadiga ah ee gudaha ee cadaadiska sare leh lagu soo warramey 8000-8200 yuan/ton. Farqiga qiimaha u dhexeeya danabka sare iyo kan toosan wuxuu ahaa 250-300 yuan/ton.

Guud ahaan, iyadoo la kordhinayo awoodda wax soo saarka polyetylen-ka gudaha iyo kororka tartiib tartiib ah ee sahayda gudaha, dhibaatada sahayda xad dhaafka ah ee warshadaha polyetylen-ka ayaa sii xoogeysatay. Inkasta oo kharashka wax soo saarka ee danabka sare uu ka sarreeyo kan toosan, sababtoo ah beddelka linear iyo metallocene ee meelaha wax soo saarka qaarkood, way adag tahay in la taageero qiimaha sare iyo faa'iidada sare ee suuqa polyetylen-ka ee daciifka ah ee hadda jira, farqiga qiimaha u dhexeeya danabka sare iyo kan toosanna si weyn ayuu u yaraaday.
