Ngaphambi kweholide Losuku Lukazwelonke, ngaphansi kwethonya lokusimama komnotho okungekuhle, isimo esintekenteke sokuthengiselana ezimakethe kanye nesidingo esingazinzile, imakethe ye-PVC ayizange ibe ngcono kakhulu. Nakuba intengo iphinde yakhuphuka, yahlala isezingeni eliphansi futhi iguquguquka. Ngemuva kweholide, imakethe yesikhathi esizayo ye-PVC ivalwa okwesikhashana, futhi imakethe yendawo ye-PVC isekelwe ikakhulukazi ezintweni zayo. Ngakho-ke, ngokusekelwa izici ezifana nokukhuphuka kwentengo ye-calcium carbide eluhlaza kanye nokufika okungalingani kwezimpahla esifundeni ngaphansi kokuvinjelwa kwezinto zokuhamba nezokuthutha, intengo yemakethe ye-PVC iqhubekile nokukhuphuka, ngokunyuka kwansuku zonke. Ku-50-100 yuan / ton. Izintengo zokuthumela zabahwebi zinyusiwe, futhi ukuthengiselana kwangempela kungaxoxisana. Kodwa-ke, ukwakhiwa komfula ongezansi akukashintshi. Udinga nje ukuthenga ikakhulukazi, uhlangothi lwesidingo aluthuthukanga kakhulu, futhi ukuthengiselana kukonke kuseyisilinganiso.
Ngokombono wemakethe, intengo yemakethe ye-PVC isezingeni eliphansi. Ithintwa yizici ezivumayo zomuntu ngamunye noma eziningi, intengo ye-PVC ithambekele ekukhuphukeni okuphansi. Kodwa-ke, esimweni semvelo yezomnotho kanye nesimo semboni ye-PVC asikathuthuki, kusengenzeka ukuqhubeka nokukhuphuka. ukucindezela, ngakho-ke isikhala sokubuyela emuva silinganiselwe. Ukuhlaziywa okuqondile kungahlukaniswa ngezici ezintathu: okokuqala, ukuqhubeka kwemakethe ye-PVC kuzocindezela ukuphindaphinda kwamanani e-PVC; okwesibili, kusekhona ukungaqiniseki ezicini zangaphandle ezifana nalolu bhubhane, okunciphisa ukuvuselelwa nokuthuthukiswa kwemboni ye-PVC; Ukuthi ukubuyiselwa kwemakethe ye-PVC yasekhaya noma yangaphandle kusadinga isikhathi esithile sokusabela, kunethuba elikhulu lokuthi kuzoba nokuthambekela okucacile ngasekupheleni kuka-Okthoba.
