    I-Trend Of PVC, I-Trend Of Carbide PVC kanye ne-Ethylene PVC

    I-PVC iwuhlobo lwepulasitiki olusetshenziswa kabanzi ezintweni zokwakha. Ngakho-ke, ngeke ithathelwe indawo isikhathi eside esikhathini esizayo, futhi izoba nethuba elihle lokufaka isicelo ezindaweni ezingathuthukisiwe esikhathini esizayo.

    Njengoba sonke sazi, kunezindlela ezimbili zokukhiqiza i-PVC, enye iyindlela evamile yomhlaba wonke ye-ethylene, kanti enye iyindlela eyingqayizivele ye-calcium carbide e-China. Imithombo yendlela ye-ethylene ikakhulukazi i-petroleum, kanti imithombo yendlela ye-calcium carbide ikakhulukazi amalahle, i-limestone nosawoti. Lezi zinsiza zigxile kakhulu eShayina. Isikhathi eside, indlela yaseChina ye-PVC ye-calcium carbide ibilokhu isendaweni ehamba phambili ngokuphelele. Ikakhulukazi kusukela ngo-2008 kuya ku-2014, amandla okukhiqiza e-PVC e-calcium ye-calcium carbide ayekhula, kodwa futhi ilethe izinkinga eziningi zokuvikela imvelo.

    Ukusetshenziswa kwamandla okukhiqizwa kwe-calcium carbide kukhulu kakhulu, ngakho-ke lokhu kuzoletha izinselelo ezithile ekuhlinzekeni kukagesi eChina. Ngenxa yokuthi ugesi ukhiqizwa ngokushisa amalahle, udinga ukusebenzisa amalahle amaningi, ngakho ukushiswa kwamalahle kuzongcolisa nakanjani umkhathi. Kodwa-ke, i-China yenze izinguquko ezithile kuzinqubomgomo phakathi neminyaka. I-China ihlezi ithuthukisa uchungechunge lwayo lwezimboni. Manje sesiyabona ukuthi i-China ithenge uwoyela omningi kwamanye amazwe, futhi amabhizinisi endawo ayakhuthazwa ukuba angenise uwoyela ukuze acwengisise imikhiqizo engaphansi komfula. Ngakho-ke, eminyakeni yamuva, abakhiqizi bezinqubo ze-ethylene abasha abasha baye bangezwa e-China, futhi wonke amandla amasha okukhiqiza e-PVC e-China eminyakeni yamuva amandla okukhiqiza inqubo ye-ethylene. Amandla okukhiqiza wendlela yaseChina ye-calcium carbide amise ukugunyazwa okusha. Ngakho-ke, esikhathini esizayo esiseduze, inani lezitshalo ze-ethylene e-China lizoqhubeka landa futhi inqubo ye-calcium carbide izoqhubeka nokuncipha. Ngokuzayo, umthamo wokuthekelisa waseChina wenqubo ye-ethylene uzoqhubeka nokukhula, futhi kancane kancane ube ngumthumeli ohamba phambili emhlabeni wenqubo ye-ethylene ye-PVC.
