Ukunyuka kwenzala yase-US kuyatshisa, i-PVC iyanyuka kwaye iyawa.

I-PVCivalwe kancinane ngoMvulo, emva kokuba uSihlalo weFederal Reserve uPowell elumkise ngomgaqo-nkqubo wokukhulula kwangaphambi kwexesha, imarike kulindeleke ukuba inyuse inzala kwakhona, kwaye imveliso kulindeleke ukuba iqalise ngokuthe ngcembe njengoko imozulu eshushu iphakanyiswa.

Kungekudala, phantsi kweempembelelo zemeko yesifo kunye nokunqongophala kwamandla kwezinye iindawo, ukuveliswa kwezityalo zePVC kuye kwamiswa kwaye kuncitshiswe. Ngomhla wama-29 ka-Agasti, i-Ofisi ye-Emergency yaseSichuan ye-Emergency yanciphisa impendulo engxamisekileyo kwisiqinisekiso sokunikezelwa kwamandla kwiimeko ezingxamisekileyo. Ngaphambili, iNational Meteorological Administration yayilindele ukuba ubushushu kwiindawo ezithile zobushushu obuphezulu emazantsi buzakwehla ngokuthe chu ukusuka ngomhla wama-24 ukuya kowama-26. Okunye ukucuthwa kwemveliso okuziswayo kusenokungagcineki, kwaye ukunqunyulwa kwamandla obushushu obuphezulu akuncedi kwicala lemfuno. Ukongeza, ezinye iindawo ziyaqhubeka nokuchatshazelwa ngubhubhane, kwaye imfuno esezantsi yomlambo ayiphucukanga. Nangona imfuno yasekhaya sele iza kungena kwixesha eliphakamileyo lexesha lonyaka, ukutsalwa kwicala lemfuno ngokuthe ngcembe kuncipha, kodwa ukuphuculwa kwexesha elifutshane akwanelanga ukuzisa ukulungelelaniswa kwempahla eyaneleyo, kwaye kwixesha eliphakathi kunye nexesha elide, ukunyuka kwemfuno ngenxa yokubuyiselwa kwemfuno yasekhaya kunzima ukuphelisa ukubuyisela kwicala lonikezelo. Imfuno eyongeziweyo neyangaphandle iyancipha phantsi koxinzelelo lokudodobala koqoqosho, kwaye ixabiso lePVC liyaqhubeka nokunyuka kwaye lisajongene noxinzelelo olunokwenzeka.

Ngokubanzi, ngenxa yokunyuka kwamva nje kokuphazamiseka kokubonelela, imeko yangaphambili yokunciphisa ngokuthe ngcembe ukunikezelwa kweemarike kunye nokulindela iimfuno kuya kuphulwa okwethutyana, okuya kwenza inkxaso ethile kwixabiso ledisk. Ngexesha elifanayo, ngenxa yokuba inzuzo ebanzi yamashishini emigodi ye-PVC yangaphandle igcina ilahleko kwaye iphakamisa ukuguqulwa kwamaxesha onyaka angaphandle, i-disk surface ibonisa ukuchasana nokuhla. Kwinqanaba lamva, ukuba imfuno yasekhaya ibuyisela kakhulu, iya kuba luncedo kwixabiso eliphantsi le-disk, kodwa ukuba ukubuyiswa kwemfuno akunamandla njengoko ukwanda kokunikezelwa, kuya kujongana noxinzelelo lokuqokelela amasheya. . Ngoko ke, phantsi komdlalo wangoku womdlalo wexesha elifutshane, elide kunye nelifutshane, kunokwenzeka ukuba uqhubeke nentshukumo yokuhamba kwe-oscillating kuluhlu oluphantsi kwixesha elifutshane, kwaye utshintsho kwimfuno lugxininiso lweenguqu zexabiso zamva nje.
