Ukwenyuka kwenzalo yase-US kuyashisa, i-PVC iyakhuphuka futhi yehle.

I-PVCIvaliwe kancane ngoMsombuluko, ngemuva kokuba uSihlalo weFederal Reserve uPowell exwayise ngokuxegisa inqubomgomo ngaphambi kwesikhathi, kulindeleke ukuthi imakethe inyuse amazinga enzalo futhi, futhi kulindeleke ukuthi umkhiqizo uqhubeke kancane kancane njengoba isimo sezulu esishisayo sikhuphuka.

Muva nje, ngaphansi kwethonya lesimo sobhubhane kanye nokuntuleka kukagesi kwezinye izindawo, ukukhiqizwa kwezitshalo ze-PVC kuye kwamiswa futhi kwancishiswa. Ngo-Agasti 29, i-Sichuan Energy Emergency Office yehlisa impendulo ephuthumayo kwisiqinisekiso sokuhlinzekwa kwamandla ezimweni eziphuthumayo. Ngaphambilini, i-National Meteorological Administration yayilindele nokuthi izinga lokushisa kwezinye izindawo ezinokushisa okuphezulu eningizimu lizokwehla kancane kancane lisuka ku-24 liye ku-26. Okunye kokunciphisa kokukhiqiza okulethwe kungase kungaqhubeki, futhi ukunciphisa kwamandla okushisa aphezulu akuhambisani nesidingo. Ngaphezu kwalokho, ezinye izindawo ziyaqhubeka nokuthintwa yilesi sifo, futhi isidingo esingezansi asikathuthuki. Nakuba isidingo sasekhaya sesizongena esizini esiphezulu sesizini, ukudonswa kwesidingo kancane kancane, kodwa ukuthuthuka kwesikhathi esifushane akwanele ukuletha ukulungiswa okwanele kwempahla, futhi esikhathini esiphakathi neside, ukwanda kwesidingo ngenxa yokubuyiselwa kwesidingo sasekhaya kunzima ukulungisa ukubuyiselwa kwesidingo sasekhaya. Isidingo esikhulayo nesangaphandle siyancipha ngaphansi kwengcindezi yokwehla komnotho, futhi inani le-PVC liyaqhubeka nokwenyuka futhi lisabhekene nengcindezi engaba khona.

Ngokuvamile, ngenxa yokwanda kwamuva kokuphazamiseka kokunikezwa, isimo sangaphambilini sokunciphisa kancane kancane ukunikezwa kwemakethe kanye nokulindela kwesidingo sizophulwa okwesikhashana, okuzokwakha ukwesekwa okuthile kwentengo yediski. Ngesikhathi esifanayo, ngenxa yokuthi inzuzo ephelele yamabhizinisi ezimayini ze-PVC angaphandle igcina ukulahlekelwa futhi ibeka phezu kokuguqulwa kwezinkathi ezingezona ezesikhathi esiphambili, ubuso bediski buveza isimo sokumelana nokwehla. Esigabeni esilandelayo, uma isidingo sasekhaya sibuya kakhulu, sizoba nomthelela ekubuyeni kabusha kwezinga eliphansi kwamanani ediski, kodwa uma ukubuyiselwa kwesidingo kungenamandla njengokwanda kokunikezwa, kuzoqhubeka nokubhekana nengcindezi yokuqongelela amasheya. Ngakho-ke, ngaphansi komjikelezo wamanje womdlalo omfushane, omude nomfushane, kungenzeka kakhulu ukuthi kuqhubeke nomkhuba wokunyakaza okushintshashintshayo ebangeni eliphansi esikhathini esifushane, futhi izinguquko ekudingweni yizona ezigxile ekushintsheni kwamanani kwakamuva.
