Iphepha lodonga, njengezinto ezibalulekileyo kumhlobiso ongaphakathi, awunakuveliswa ngaphandle kwe-PVC.HECE, i-PVC ifakelwe ukubola ngexesha lokusebenza kobushushu obuphakathi, echaphazela umgangatho wemveliso.I-stabilizers ye-PVC, ngakumbi i-potassium ye-potassium yezilobi, ube yizongezo eziphambili kwimveliso yephephadonga.
Umkhamikhali ophezulu, njengomenzi weStabilimizwe oneminyaka engama-30 yamava oqeqesho, uhlala uzibophelele ekuboneleleni abathengi ngezisombululo ezinobuchule kunye nokusebenza kwemveliso efanelekileyo.
I-potassium ye-bultium ze-chazilium stibizerInokulawula ngempumelelo inkqubo ye-PVC, yenze i-iyunifomu kwaye icocekile i-foam ye-Will Planethi, ingavuseleli ubunzima bemveliso, kodwa ikwandisa ukusebenza kwephepha, ukuhlangabezana neemfuno zephephadonga eliphezulu. Ukulungiswa kobushushu obuphakathi, i-potasium ye-chaxilium ye-zinc inokuthintela i-PVC ukuba inciphise i-PVC, ukunqanda ukunikezelwa kweWellpaper, i-Blight okanye i-Bleble okanye i-BUBBle imibala kunye nombala ogudileyo. Ayinazo izinyithi ezinzima njenge-computer kunye neCadmium, zihambelana nemigangatho yendalo esingqongileyo efana ne-rohs kwaye ifikelele, kwaye ihlangabezana nemfuno yentengiso yeemveliso eziluhlaza. Ngokuvumelana kakuhle kunye nokuhambelana, kunokuphucula ukuqukuqeka kwe-PVC, ukunciphisa ukusetyenziswa kwamandla, kunye nokuphucula ukusebenza kwemveliso.
Imichiza ephezulu inika isikhokelo esipheleleyo esivela kunyulo sokunyulu senkqubo yokuqhubela phambili, ukuqinisekisa ukusetyenziswa kakuhle kwezinto zokuzinza kwi-foaming kunye namanye amanqanaba okulungisa. Ngemfuno eyandayo yokukhanya kokukhanya, ubuhlobo bokusingqongileyo, kunye nokusebenza kwimakethi yephepha le-yoll, indima ye-stassium ye-chassium ze-zinc iya kuba ibaluleke ngakumbi.Iikhemikhali zeJoyUya kuqhubeka ukuqhutywa yinto entsha, ukuqalisa ukusebenza kweemveliso eziphezulu kunye nendawo ekubuhlobo ukuxhasa uphuhliso oluzinzileyo loshishino lweWellpenit.
IXESHA LOKUQALA: NgoFebwe-18 ukuya kwi-1825
