Izinga lenzalo lase-US liyashisa, i-PVC iyakhuphuka futhi yehle.

I-PVCivalwe kancane ngoMsombuluko, ngemuva kokuthi uSihlalo weFederal Reserve uPowell exwayise ngomgomo wokuxegisa ngaphambi kwesikhathi, imakethe kulindeleke ukuthi iphinde inyuse inzalo, futhi ukukhiqizwa kulindeleke ukuthi kuqale kabusha kancane kancane njengoba isimo sezulu esishisayo siphakanyiswa.

Muva nje, ngaphansi kwethonya lesimo esiwubhubhane kanye nokuntuleka kwamandla kwezinye izindawo, ukukhiqizwa kwezitshalo ze-PVC kuye kwamiswa futhi kwancishiswa. Ngomhla zingama-29 kuNcwaba, Ihhovisi Lezimo Eziphuthumayo laseSichuan lehlisa impendulo ephuthumayo esiqinisekweni sokuhlinzekwa kwamandla ezimeni eziphuthumayo. Phambilini, iNational Meteorological Administration ibilindele ukuthi izinga lokushisa kwezinye izindawo ezinezinga eliphezulu lokushisa eningizimu lizokwehla kancane kancane lisuka zingama-24 liye kuma-26. Okunye ukuncishiswa kokukhiqiza okulethwayo kungase kungakwazi ukusimama, futhi ukunqanyulwa kwamandla okushisa aphezulu akuhambisani nohlangothi lwesidingo. Ngaphezu kwalokho, ezinye izindawo ziyaqhubeka nokuthinteka kulolu bhubhane, futhi isidingo esingaphansi komfula asikabi ngcono. Nakuba isidingo sasekhaya sesizongena enkathini ephakeme yesizini, ukudonsa ohlangothini lwesidingo kuncipha kancane kancane, kodwa ukuthuthukiswa kwesikhashana akwanele ukuletha ukuthuthukiswa okwanele kwe-inventory, futhi esikhathini esimaphakathi nesikhathi eside, isidingo siyakhula. ngenxa yokubuyiselwa kwesidingo sasekhaya kunzima ukuqeda ukutholakala kohlangothi lokunikezela. Isidingo esikhulayo nesangaphandle siyehla ngaphansi kwengcindezi yokuwohloka komnotho, futhi ukulinganisa kwe-PVC kuyaqhubeka nokukhuphuka futhi kusabhekene nengcindezi engaba khona.

Ngokuvamile, ngenxa yokwanda kwakamuva kokuphazamiseka kokuhlinzekwa, isimo sangaphambilini sokunciphisa kancane kancane ukunikezwa kwemakethe kanye nokulindela kwesidingo kuzophulwa okwesikhashana, okuzokwenza ukusekelwa okuthile kwentengo yediski. Ngesikhathi esifanayo, ngenxa yokuthi inzuzo ephelele yamabhizinisi ezimayini ze-PVC yangaphandle igcina ukulahlekelwa futhi iphakamisa ukuguqulwa kwezinkathi zonyaka ongekho phezulu, indawo yediski iveza isimo sokumelana nokwehla. Esikhathini esilandelayo, uma isidingo sasekhaya silulama kakhulu, sizoba nomthelela ekubuyiselweni kwezinga eliphansi lamanani ediski, kodwa uma ukubuyiswa kwesidingo kungenamandla njengokwanda kokuhlinzekwa, kusazobhekana nokucindezela kokuqongelela amasheya. . Ngakho-ke, ngaphansi komjikelezo wegeyimu wamanje womfushane, omude futhi omfushane, kungenzeka ukuthi uqhubeke nomkhuba wokunyakaza kwe-oscillating ebangeni eliphansi esikhathini esifushane, futhi izinguquko ezifunwayo zigxile ekushintsheni kwentengo yakamuva.
