Isbeddelka PVC, Isbeddelka PVC-ga Carbide iyo Ethylene PVC

PVC waa nooc ka mid ah balaastikada si weyn loogu isticmaalo qalabka dhismaha. Sidaa darteed, lama beddeli doono muddo dheer mustaqbalka, waxayna yeelan doontaa fursado badan oo lagu dabaqi karo meelaha aan horumarsanayn mustaqbalka.

Sida aan wada ognahay, waxaa jira laba siyaabood oo lagu soo saaro PVC, mid waa habka caalamiga ah ee ethylene, kan kalena waa habka gaarka ah ee calcium carbide ee Shiinaha. Ilaha habka ethylene inta badan waa batroolka, halka ilaha habka calcium carbide ay inta badan yihiin dhuxusha, dhagaxa nuuradda iyo milixda. Khayraadkani waxay inta badan ku urursan yihiin Shiinaha. Muddo dheer, habka PVC ee calcium carbide ee Shiinaha ayaa ku jiray booska ugu horreeya. Gaar ahaan laga bilaabo 2008 ilaa 2014, awoodda wax soo saarka PVC ee Shiinaha ee habka calcium carbide ayaa sii kordheysay, laakiin waxay sidoo kale keentay dhibaatooyin badan oo ilaalinta deegaanka ah.

Isticmaalka korontada ee wax soo saarka kaalshiyamka ee kalsiyum carbide aad ayuu u weyn yahay, sidaa darteed tani waxay caqabado ku noqon doontaa korontada Shiinaha. Maadaama korontada laga dhaliyo dhuxusha la shido, waxay u baahan tahay inay isticmaasho dhuxul badan, sidaas darteed gubashada dhuxusha waxay si lama huraan ah u wasakhayn doontaa jawiga. Si kastaba ha ahaatee, Shiinaha wuxuu sameeyay isbeddello qaar siyaasadaha sanadihii la soo dhaafay. Shiinaha si joogto ah ayuu u casriyeynayaa silsiladdiisa warshadaha. Hadda waxaan arki karnaa in Shiinaha uu soo dhoofiyay saliid badan, shirkadaha maxalliga ahna waxaa lagu dhiirigelinayaa inay soo dejiyaan saliid si ay u sifeeyaan alaabada hoos u socota. Sidaa darteed, sannadihii la soo dhaafay, dhowr soo-saarayaal cusub oo habka ethylene ah ayaa lagu daray Shiinaha, 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 kaalshiyamka ee kalsiyum carbide ee Shiinaha ayaa joojisay ansixinta cusub. Sidaa darteed, mustaqbalka dhow, tirada warshadaha ethylene ee Shiinaha ayaa sii wadi doonta inay korodho habka kaalshiyamka carbide-ka ayaa sii yaraan doona. Mustaqbalka, mugga dhoofinta ee habka ethylene ee Shiinaha ayaa sii wadi doona inuu sii kordho, oo si tartiib tartiib ah u noqon doona dhoofinta ugu horreysa adduunka ee habka ethylene PVC.
