Wonke umuntu uyazi mayelana nezinsiza zokucubungula ze-PVC. Yiziphi izinkinga ngezinsiza zokucubungula ze-PVC embonini?

1. Ubuchwepheshe be-MBS nokuthuthukiswa kuhamba kancane, futhi imakethe ibanzi, kodwa isabelo semakethe semikhiqizo yasekhaya siphansi.

Nakuba sekudlule iminyaka engaphezu kwengu-20 yokuthuthuka, imboni yasekhaya ye-MBS okwamanje isencane, futhi ayikho imikhiqizo yenkampani engaqhudelana ngokugcwele nemikhiqizo yangaphandle efana nezinsiza zokucubungula ze-PVC. Amabhizinisi amaningi akhona abhekene nochungechunge lwezinkinga ezinjengokukhethwa kwemishini enganele, izinqubo zokuhlanganisa ezingazinzile, nokuntuleka kwempumelelo kubuchwepheshe bokuhlanganiswa. Ngisho namabhizinisi amaningi awanayo eyawo imishini ye-styrene butadiene latex synthesis futhi angathenga kuphela i-non-MBS ethize ye-styrene butadiene latex yokukhiqiza kwe-MBS, futhi ikhwalithi yemikhiqizo yabo ingacatshangwa. Okwamanje, imikhiqizo eminingi eyethulwa emakethe incike enzuzweni yamanani futhi isetshenziswa emikhiqizweni ye-PVC engadingi ikhwalithi ephezulu yomkhiqizo. Ezimakethe ezisezingeni eliphezulu, isabelo semakethe sincane futhi ayikakabi nomthelela ezinkampanini zangaphandle. Kulindeleke ukuthi umthamo wokungenisa impahla ngo-2006 ube phakathi kwamathani ayi-50000 nezi-60000, okuzoba ngaphezu kuka-70% wesamba esifunekayo.

2. Bambalwa abacwaningi kanye nezikhungo zocwaningo, ezihlulekile ukwakha amandla ahlangene okuphumelela kwesayensi nezobuchwepheshe.

Nakuba i-MBS ifakwe kuhlu njengephrojekthi kazwelonke yocwaningo lwesayensi nobuchwepheshe izikhathi eziningi, ayikazuzi impumelelo ebalulekile. Isizathu esiyinhloko ukuthi kukhona abacwaningi abambalwa kanye nokutshalwa kwezimali okuncane kwezobuchwepheshe. Okwamanje, kuseyizikhungo zocwaningo lwemboni ezenza izivivinyo ezizimele futhi zifuna impumelelo, kodwa le modeli yocwaningo nentuthuko ingabhekwa njengeyimfundamakhwela uma iqhathaniswa neqembu langaphandle kanye namaqembu amakhulu ocwaningo lwesayensi.

3. Njengamanje, izinga lezinsiza zokucubungula i-PVC e-China liseduze nemikhiqizo yangaphandle, kodwa ngenxa yemingcele yentengo ye-CPE, kunzima ukuyikhuthaza. Ukuya emhlabeni wonke kanye nokuncintisana nemikhiqizo yangaphandle emakethe yamazwe ngamazwe kuzoba yisinqumo esihle. Kodwa-ke, umkhiqizo owodwa wamanje kanye nokuzinza okubi kuzoba yinkinga ephuthumayo ukuze abangaphakathi embonini bayixazulule
