Wonke umuntu uyazi ngezinsiza zokucubungula i-PVC. Yiziphi izinkinga ngezinsiza zokucubungula i-PVC embonini?

1. Ubuchwepheshe nentuthuko ye-MBS kuhamba kancane, futhi imakethe ibanzi, kodwa isabelo semakethe semikhiqizo yasekhaya siphansi kakhulu.

Nakuba isidlule iminyaka engaphezu kwengu-20 yentuthuko, imboni yasekhaya ye-MBS okwamanje isencane, futhi ayikho imikhiqizo yenkampani engancintisana ngokugcwele nemikhiqizo yangaphandle njengezinsiza zokucubungula i-PVC. Iningi lamabhizinisi akhona libhekene nochungechunge lwezinkinga ezifana nokukhethwa kwemishini enganele, izinqubo zokwenziwa ezingazinzile, kanye nokuntuleka kwentuthuko kwezobuchwepheshe bokwenziwa. Ngisho namabhizinisi amaningi awanawo imishini yawo yokwenziwa kwe-styrene butadiene latex futhi angathenga kuphela i-styrene butadiene latex engeyona i-MBS ethile yokukhiqizwa kwe-MBS, futhi ikhwalithi yemikhiqizo yawo ingacatshangwa. Njengamanje, imikhiqizo eminingi eyethulwa emakethe incike ezinzuzweni zamanani futhi isetshenziswa emikhiqizweni ye-PVC engadingi ikhwalithi ephezulu yomkhiqizo. Emakethe ephezulu, isabelo semakethe sincane kakhulu futhi asikakhi mthelela ezinkampanini zakwamanye amazwe. Kulindeleke ukuthi inani lokungenisa ngo-2006 lizoba phakathi kwamathani angu-50000 no-60000, okubalwa ngaphezu kwama-70% esidingo sonke.

2. Bambalwa abacwaningi nezikhungo zocwaningo, ezihlulekile ukwakha amandla ahlangene okuthuthukisa isayensi nezobuchwepheshe.

Nakuba i-MBS ibhalwe njengomsebenzi wocwaningo lwesayensi nobuchwepheshe kazwelonke izikhathi eziningi, ayikakafinyeleli impumelelo ebalulekile. Isizathu esiyinhloko ukuthi bambalwa abacwaningi kanye nokutshalwa kwezimali okuncane kwezobuchwepheshe. Njengamanje, kuseyizikhungo zocwaningo lwemboni ezenza izivivinyo ezizimele futhi zifuna impumelelo, kodwa lo modeli wocwaningo nentuthuko ungabhekwa njengongafundile uma uqhathaniswa namaqembu angaphandle kanye namaqembu amakhulu ocwaningo lwesayensi.

3. Njengamanje, izinga lezinsiza zokucubungula i-PVC eShayina liseduze nelemikhiqizo yangaphandle, kodwa ngenxa yemingcele yentengo ye-CPE, kunzima ukuyikhuthaza. Ukuya emhlabeni wonke nokuncintisana nemikhiqizo yangaphandle emakethe yamazwe ngamazwe kuzoba ukukhetha okuhle. Kodwa-ke, umkhiqizo owodwa wamanje kanye nokuzinza okubi kuzoba yinkinga ephuthumayo okufanele ixazululwe ngabantu abangaphakathi embonini.
