Hordhac ku saabsan Awoodda PVC ee Shiinaha iyo Caalamka

Marka loo eego tirakoobka 2020, wadarta guud ee awoodda wax soo saarka PVC ee adduunka ayaa gaartay 62 milyan oo tan, wadarta guudna waxay gaartay 54 milyan oo tan. Dhammaan dhimista wax-soo-saarka waxay ka dhigan 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 yaraado awoodda wax-soo-saarka. Sababtoo ah qiimaha sare ee wax soo saarka PVC ee Yurub iyo Japan, awoodda wax soo saarka PVC ee caalamiga ah waxay inta badan ku urursan tahay Waqooyi Bari Asia, taas oo Shiinuhu leeyahay kala badh awoodda wax soo saarka PVC ee caalamiga ah.

Marka loo eego xogta dabaysha, sanadka 2020, Shiinaha, Mareykanka iyo Japan ayaa ah meelaha muhiimka ah ee wax soo saarka PVC ee adduunka, iyadoo awoodda wax soo saarku ay ku xisaabtameyso 42%, 12% iyo 4% siday u kala horreeyaan. Sannadka 2020, saddexda shirkadood ee ugu sarreeya awoodda wax-soo-saarka sannadlaha ah ee PVC waxay ahaayeen Westlake, shintech iyo FPC. Sannadka 2020, awoodda wax-soo-saarka sannadlaha ah ee PVC waxay ahayd 3.44 milyan tan, 3.24 milyan tan iyo 3.299 milyan oo tan siday u kala horreeyaan. Marka labaad, shirkadaha leh awoodda wax-soo-saarka in ka badan 2 milyan oo tan ayaa sidoo kale ka mid ah inovyn. Wadarta guud ee awoodda wax-soo-saarka Shiinaha waa 25 milyan oo tan oo kale, iyada oo wax soo saarkeedu yahay 21 milyan oo tan sanadka 2020. Waxaa jira in ka badan 70 warshadood oo PVC ah oo Shiinaha ah, 80% ka mid ah waa habka calcium carbide iyo 20% waa habka ethylene.

Inta badan habka carbide calcium waxa uu ku urursan yahay meelaha qani ku ah khayraadka dhuxusha sida Inner Mongolia iyo Xinjiang. Goobta dhirta ee geeddi-socodka ethylene waxay ku taallaa aagagga xeebta sababtoo ah alaabta ceeriin ee VCM ama ethylene waxay u baahan tahay in la soo dejiyo. Awoodda wax-soo-saarka Shiinaha waxay ku dhowdahay kala badh adduunka, iyo ballaarinta joogtada ah ee silsiladda warshadaha ee Shiinaha ee kor u kaca, awoodda wax-soo-saarka PVC ee habka ethylene waxay sii wadi doontaa inay kordhiso, Shiinuhuna wuxuu sii wadi doonaa inuu baabi'iyo saamiga caalamiga ah ee PVC.
