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 adduunka ee PVC ann ... -
Isbeddelka Mustaqbalka ee Resin PVC
PVC waa nooc caag ah oo si weyn loogu isticmaalo qalabka dhismaha. Sidaa darteed, lama beddeli doono muddo dheer mustaqbalka, waxayna yeelan doontaa rajooyin codsi oo weyn oo mustaqbalka ah meelaha aan horumarsaneyn mustaqbalka. Sida aan wada ognahay, waxaa jira laba siyaabood oo loo soo saaro PVC, mid waa habka caalamiga ah ee ethylene, iyo habka kale ee calcium carbide ee Shiinaha. Ilaha habka ethylene inta badan waa batroolka, halka ilaha habka karbidhida calcium ay u badan yihiin dhuxusha, nuuradda iyo cusbada. Khayraadkani waxay inta badan ku urursan yihiin Shiinaha. Muddo dheer, PVC-ga Shiinaha ee habka kaarbiid ee kaalshiyamku wuxuu ku jiray booska hogaaminta buuxda. Gaar ahaan laga bilaabo 2008 ilaa 2014, awoodda wax soo saarka ee PVC ee habka calcium carbide ayaa sii kordhayay, laakiin sidoo kale waxay keentay ... -
Waa maxay xabagta PVC?
Polyvinyl chloride (PVC) waa polymer lagu sameeyay vinyl chloride monomer (VCM) oo ku jira peroxide, azo compound iyo hindiseyaal kale ama sida ku cad habka polymerization xagjirka ah ee bilaashka ah ee hoos yimaada ficilka iftiinka iyo kuleylka. Vinyl chloride homopolymer iyo vinyl chloride copolymer ayaa si wada jir ah loogu tilmaamaa xabagta vinyl chloride.
