Ngaphambi kweholide yeSizwe, phantsi kwempembelelo yokubuyiselwa koqoqosho okubi, umoya obuthathaka wentengiselwano yemarike kunye nemfuno engaguqukiyo, imakethi yePVC ayizange iphucuke kakhulu. Nangona ixabiso libuyele umva, lahlala likwinqanaba eliphantsi kwaye litshintshatshintsha. Emva kweholide, imakethi yePVC yexesha elizayo ivaliwe okwethutyana, kwaye imakethi yePVC isekelwe kakhulu kwizinto zayo. Ke ngoko, ixhaswa zizinto ezinje ngokunyuka kwexabiso le-calcium carbide eluhlaza kunye nokufika okungalinganiyo kweempahla kulo mmandla phantsi komda wezothutho kunye nothutho, ixabiso lemakethi yePVC liqhubekile nokunyuka, ngokunyuka kwemihla ngemihla. Kwi-50-100 yuan / ton. Amaxabiso okuthunyelwa kwabarhwebi anyusiwe, kwaye intengiselwano yokwenyani inokuxoxiswana. Nangona kunjalo, ulwakhiwo olusezantsi alukangqinelani. Kufuneka nje uthenge ikakhulu, icala lemfuno alikaphucuki kakhulu, kwaye intengiselwano iyonke isengumndilili.
Ngokwembono yemarike, ixabiso lemarike ye-PVC likwinqanaba eliphantsi. Lichatshazelwa zizinto eziluncedo zomntu ngamnye okanye ezininzi, ixabiso le-PVC linokuhla kwe-rebound ephantsi. Nangona kunjalo, kwimeko yezoqoqosho kunye nemeko yeshishini le-PVC ayiphucukanga, kusenokwenzeka ukuqhubeka nokunyuka. uxinzelelo, ngoko ke indawo yohla kwe-rebound incinci. Uhlalutyo oluthile lunokwahlulwa lube ziinkalo ezintathu: okokuqala, ukuqhubeka kokubonelela ngokugqithisileyo kwimarike ye-PVC kuya kucinezela uhla kwexabiso le-PVC; okwesibini, kusekho ukungaqiniseki kwizinto zangaphandle ezifana nobhubhane, okuthintela ukubuya nophuhliso lweshishini le-PVC; Nokuba ukubuyiselwa kwimarike ye-PVC yasekhaya okanye yangaphandle kusafuna ixesha elithile lokuphendula, kukho amathuba aphezulu okuba kuya kubakho umkhwa ocacileyo ekupheleni kuka-Okthobha.
