Kubomi bemihla ngemihla, siya kufumanisa ukuba iimveliso zeplastiki ezininzi ziya kuba nevumba elithile xa ziqala ukusetyenziswa.Ngokomzekelo, ezinye iimveliso ze-polyethylene kunye ne-polypropylene ziya kuba nephunga elimnandi ekuqaleni kokusetyenziswa, kwaye iphunga liya kuba lincinci emva kwexesha lokusetyenziswa., Kutheni ezi mveliso zeplastiki zivumba?
Ezi zivumba kwiiplastiki zivela ikakhulu kwizongezo ezongeziweyo kwinkqubo yokwenziwa kweplastiki.Oku kubangelwa ukongezwa kwe-solvents kunye nenani elincinci labaqalisi kunye nezinye izongezo ngexesha le-polymerization ye-polyethylene kunye ne-polypropylene resins.Emva kokuhlamba, ukuhluzwa, njl., ngamanye amaxesha inani elincinci lezinto ezincedisayo ezikhankanywe ngasentla ziya kuhlala, kwaye ukongezelela, inani elincinci le-polymer-weight-weight polymer liya kuhlala kwi-resin.Ngethuba lokubunjwa kunye nokucutshungulwa kweemveliso zeplastiki, ezi zinto ziya kubonakaliswa kumaqondo okushisa aphezulu ukuba zibalekele iphunga elingaqhelekanga kwaye zihlale phezu kwemveliso.
Ukongeza, abanye abavelisi baya kongeza i-turpentine njengoncedo lokudaya xa idayi yeplastiki.Ukuba isetyenziswe kakhulu, iphunga le-turpentine liya kuphuma kwimveliso.Inyamalala kancinci kwaye ayinayo impembelelo kwimpilo yabantu.Nangona kunjalo, ukuba iphunga linzima kakhulu kwaye likhona ixesha elide, liya kuba nefuthe elithile kwimpilo yabantu.
Ke ngoko, xa kuthengwa iimveliso zeplastiki kufuneka sikhethe iimveliso zeplastiki ezinezixhobo ezikhuselekileyo, umgangatho olungileyo kunye nokhuseleko oluphezulu.
