Hordhac ku saabsan Awoodda PVC ee Shiinaha iyo Caalamka

Sida laga soo xigtay tirakoobkii 2020, wadarta guud ee wax soo saarka PVC-ga adduunka ayaa gaartay 62 milyan oo tan, wadarta guud ee wax soo saarkana waxay gaartay 54 milyan oo tan. Dhammaan hoos u dhaca wax soo saarka waxay la macno tahay in awoodda wax soo saarku aysan socon 100%. Sababtoo ah masiibooyinka dabiiciga ah, siyaasadaha maxalliga ah iyo arrimo kale, wax soo saarku waa inuu ka yar yahay awoodda wax soo saarka. Sababtoo ah qiimaha wax soo saarka sare ee PVC ee Yurub iyo Japan, awoodda wax soo saarka PVC-ga adduunka ayaa inta badan ku urursan Waqooyi-bari Aasiya, oo Shiinuhu leeyahay qiyaastii kala bar awoodda wax soo saarka PVC-ga adduunka.

Sida laga soo xigtay xogta dabaysha, sannadkii 2020, Shiinaha, Mareykanka iyo Japan waa meelaha muhiimka ah ee wax soo saarka PVC ee adduunka, iyadoo awoodda wax soo saarku ay tahay 42%, 12% iyo 4% siday u kala horreeyaan. Sannadkii 2020, saddexda shirkadood ee ugu sarreeya awoodda wax soo saarka sanadlaha ah ee PVC ee adduunka waxay ahaayeen Westlake, shintech iyo FPC. Sannadkii 2020, awoodda wax soo saarka sanadlaha ah ee PVC waxay ahayd 3.44 milyan oo tan, 3.24 milyan oo tan iyo 3.299 milyan oo tan siday u kala horreeyaan. Marka labaad, shirkadaha leh awood wax soo saar oo ka badan 2 milyan oo tan ayaa sidoo kale ku jira inovyn. Wadarta awoodda wax soo saarka ee Shiinaha waa 25 milyan oo tan oo kale, iyadoo wax soo saarku yahay 21 milyan oo tan sannadkii 2020. Waxaa jira in ka badan 70 soosaarayaal PVC ah oo ku sugan Shiinaha, 80% oo ka mid ah waa habka kaalshiyamka kaarbiidka iyo 20% waa habka ethylene.

Inta badan habka kaalshiyamka carbide-ka waxaa lagu ururiyaa meelo hodan ku ah kheyraadka dhuxusha sida Inner Mongolia iyo Xinjiang. Goobta warshadda ee habka ethylene-ku wuxuu ku yaal meelaha xeebaha sababtoo ah walxaha ceeriin ee VCM ama ethylene waa in la soo dhoofiyaa. Awoodda wax soo saarka Shiinaha waxay ka kooban tahay ku dhawaad ​​​​kala bar adduunka, iyadoo si joogto ah loo ballaarinayo silsiladda warshadaha ee Shiinaha, awoodda wax soo saarka PVC ee habka ethylene ayaa sii wadi doonta inay korodho, Shiinuhuna wuxuu sii wadi doonaa inuu burburiyo saamiga caalamiga ah ee PVC.
