Isbeddelka PVC-ga, Isbeddelka Carbide PVC iyo Ethylene 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 dhibaatooyin badan oo ilaalinta deegaanka.

Isticmaalka korantada ee wax soo saarka kaarbiid-ka kaalshiyamku aad buu u weyn yahay, markaa tani waxay caqabad ku noqon doontaa tamarta Shiinaha. Sababtoo ah korontadu waxay ka dhalataa gubasho dhuxusha, waxay u baahan tahay inay isticmaasho dhuxul badan, sidaas darteed gubashada dhuxusha waxay si lama filaan ah u wasakhaysaa jawiga. Si kastaba ha ahaatee, Shiinaha ayaa isbedel ku sameeyay siyaasadaha sanadihii la soo dhaafay. Shiinaha ayaa si joogto ah u cusbooneysiinaya silsiladeeda warshadaha. Hadda waxaan arki karnaa in Shiinuhu uu soo dhoofiyay shidaal badan, waxaana shirkadaha maxalliga ah lagu dhiirigelinayaa inay soo dejiyaan saliid si loo sifeeyo wax soo saarka hoose. Sidaa darteed, sannadihii la soo dhaafay, dhowr warshadood oo geeddi-socod cusub ah ayaa lagu daray Shiinaha, iyo dhammaan awoodda wax-soo-saarka cusub ee PVC ee Shiinaha sannadihii la soo dhaafay waa awoodda wax-soo-saarka ee habka ethylene. Awoodda wax-soo-saarka ee habka kaarbiid-ka calcium ee Shiinaha ayaa joojisay oggolaanshaha cusub. Sidaa darteed, mustaqbalka dhow, tirada dhirta ethylene ee Shiinaha ayaa sii wadi doonta inay kordhiso, habka calcium carbide wuxuu sii wadi doonaa inuu hoos u dhaco. Mustaqbalka, mugga dhoofinta Shiinaha ee geeddi-socodka ethylene wuxuu sii wadi doonaa inuu kordhiyo, oo si tartiib tartiib ah u noqdo dhoofiyaha ugu horreeya adduunka ee habka ethylene PVC.
