Kutshanje, ngenxa yogcino olugxininisiweyo kunye nokucuthwa komthwalo kwamanye amashishini emveliso, izinga lomthwalo weshishini lePVC liwele kwinqanaba eliphantsi, kwaye unikezelo lwePVC lwehlile. Nangona kunjalo, njengoko ukudinwa kwecala elisezantsi kuyaqhubeka, unikezelo lwendawo kwintengiso luselula, inxenye yamashishini emveliso yePVC isajongene nokuthengisa kunye noxinzelelo lwempahla. Icala lemfuno alikabonakali naziphi na iimpawu ezicacileyo zokubuyiswa, kwaye ukuthunyelwa kwamanye amazwe kulindeleke ukuba kube buthathaka, ukunikezelwa ngokubanzi kokubonelela ngo-Agasti kulindeleke ukuba kuqhubeke.
Kwiminyaka yakutshanje, izinga lomthwalo weshishini lasekhaya PVC liye lehla xa kuthelekiswa nexesha elidlulileyo, unikezelo lwePVC luye lwehla, imboni ye-PVC yangoku ukugcina izinga lomthwalo eliphantsi ekuqaleni kwinqanaba.
Kwelinye icala, ngenxa yogcino oluthe kratya lwezinye iifektri ezinkulu kwixesha lamva nje, ilahleko yolondolozo inyuke kakhulu xa kuthelekiswa nexesha langaphambili. Kwiiveki ezimbini ezidlulileyo, ilahleko yethiyori yePVC ngenxa yokupaka kunye nokugcinwa kweetoni ze-63,530 kunye neetoni ze-67,790 ngokulandelanayo, zifikelele kwinqanaba eliphezulu kakhulu ngonyaka.
Kwelinye icala, ngenxa yobushushu obuphezulu, ilahleko kunye nezinye izizathu, amanye amashishini acutha umthwalo, kwaye amanye amashishini anocutho olukhulu kwisantya somthwalo wokuqalisa, nkqu nendawo yokupaka okwethutyana yamashishini emveliso ngamnye.
Kutshanje, uninzi lwee-odolo zamashishini emveliso ye-PVC ayikalungi, ii-odolo zeemveliso aziphucukanga kakhulu, umdla wokuthenga izinto ezikrwada awukho phezulu, uninzi lwamashishini emveliso ayaqhubeka nokuhlangabezana neemfuno zokuzaliswa-based, eziphantsi. ukwamkelwa kwamaxabiso aphezulu, inxalenye yexesha apho amaxabiso e-PVC angabonanga ukunyuka kweemvakalelo. Kwiiveki ezimbini ezidlulileyo, i-market market ye-PVC inxalenye yexesha lokurhweba ukukhanya, i-market for traders more trade flow between the source, downstream imfuno yokwenene isebuthathaka. Njengoko kunokubonwa kwi-Figure 4, nangona umzila wamva nje wexabiso elincinci le-PVC ye-inventory yentlalontle, kodwa ixabiso elipheleleyo le-inventory yentlalo lisagcinwe kwinqanaba eliphezulu kakhulu.
Ukongeza kwi-inventory yentlalo yexabiso elipheleleyo lisagcinwe kwinqanaba eliphezulu, uluhlu lwamva nje lwemveliso yePVC luqhubekile lukhula, kwaye izinga lokukhula likhulu. Umahluko ka-2021 wawuphezulu kakhulu ngexesha elifanayo.
Nangona lulonke utshintsho lwee-odolo zangaphambili zamashishini kule minyaka yakutsha nje alukho lukhulu, kodwa amanye amashishini emveliso akhona ukulibaziseka kokuhanjiswa kweodolo yabathengi, amanye amashishini uluhlu lwempahla yonyuka kakhulu. Lilonke, nangona kukho ukuhla okuncinci kwindlela yokugcinwa kwempahla yentlalo yakutshanje, kodwa ukuhla kungaphantsi kakhulu kunomlinganiselo wemveliso yokuqokelela uluhlu lwemizi-mveliso. Ngenxa yoko, unikezelo lwamabala kwimarike luhlala lukhululekile.
Nangona kuye kwakho ukuncitshiswa okubonakalayo kokubonelelwa kwixesha elisondeleyo, kulindeleke ukuba imeko yokubonelela ngokugqithisileyo ayiyi kuguqulwa ngexesha elifutshane, ngokusekelwe ekulindelweni kokulandela ukubonelela kunye nemfuno.
