Ngaphambi kweholide likaSuku Lukazwelonke, ngaphansi kwethonya lokululama komnotho okubi, isimo sokuthengiselana emakethe esibuthakathaka kanye nesidingo esingazinzile, imakethe ye-PVC ayizange ithuthuke kakhulu. Nakuba intengo ibuyele emuva, yahlala isezingeni eliphansi futhi yashintshashintsha. Ngemva kweholide, imakethe yesikhathi esizayo ye-PVC ivaliwe okwesikhashana, futhi imakethe ye-PVC isekelwe kakhulu ezintweni zayo. Ngakho-ke, isekelwa yizici ezifana nokwenyuka kwentengo ye-calcium carbide eluhlaza kanye nokufika okungalingani kwezimpahla esifundeni ngaphansi kokuvinjelwa kwempahla kanye nezokuthutha, intengo yemakethe ye-PVC iqhubekile nokukhuphuka, ngokunyuka kwansuku zonke. Ku-50-100 yuan / ton. Amanani okuthumela abahwebi aphakanyisiwe, futhi ukuthengiselana kwangempela kungaxoxiswana ngakho. Kodwa-ke, ukwakhiwa okuphansi akukaguquki. Kudingeka nje ukuthenga ikakhulukazi, uhlangothi lokufunwa alukathuthuki kakhulu, futhi ukuthengiselana konke kusesesilinganisweni.
Ngokombono wemakethe, intengo yemakethe ye-PVC isezingeni eliphansi. Ithintwa yizici ezizuzisayo ngazinye noma eziningi, intengo ye-PVC ithambekele ekukhuphukeni okuphansi. Kodwa-ke, esimweni sezomnotho kanye nesimo semboni ye-PVC asikathuthuki, kusengenzeka ukuqhubeka nokukhuphuka. ingcindezi, ngakho-ke isikhala sokukhuphuka sinqunyelwe. Ukuhlaziywa okuthile kungahlukaniswa ngezici ezintathu: okokuqala, ukuqhubeka kokuhlinzekwa ngokweqile kwemakethe ye-PVC kuzocindezela ukwehla kwamanani e-PVC; okwesibili, kusekhona ukungaqiniseki ngezici zangaphandle njengobhubhane, okunciphisa ukubuya kanye nentuthuko yemboni ye-PVC; Kungakhathaliseki ukuthi ukubuya kwemakethe ye-PVC yasekhaya noma yangaphandle kusadinga isikhathi esithile sokuphendula, kunethuba elikhulu lokuthi kuzoba nomkhuba ocacile ngasekupheleni kuka-Okthoba.
