Ungahlola kanjani ukuthi inqubo yokukhiqiza yesikhwama se-Eva ihambisana nemvelo ngempela?
Esimeni sanamuhla sokwandisa ukuqwashisa ngemvelo, sekubaluleke kakhulu ukuhlola ukuthi inqubo yokukhiqiza yeIzikhwama ze-EVAihambisana nemvelo. Okulandelayo uchungechunge lwezinyathelo namazinga angasisiza sihlole ngokujulile ubungane bemvelo benqubo yokukhiqiza izikhwama ze-EVA.
1. Ubungane bemvelo bezinto ezingavuthiwe
Okokuqala, sidinga ukubheka ukuthi izinto zokusetshenziswa zesikhwama se-EVA ziyahambisana yini nemvelo. Izinto ze-EVA ngokwazo azizona izinto ezinobuthi futhi ezingenabungozi ezihambisana nemvelo. Ngesikhathi senqubo yokukhiqiza, kufanele kuqinisekiswe ukuthi impahla ye-EVA ayinazo izinto eziyingozi futhi ithobelana nezindinganiso nemithethonqubo efanele yezemvelo. Ngaphezu kwalokho, izinto ze-EVA kufanele zithobele izindinganiso zamazwe ngamazwe njenge-RoHS Directive kanye ne-REACH Regulation, ekhawulela ukusetshenziswa kwezinto eziyingozi futhi edinga ukusetshenziswa okuphephile kwamakhemikhali.
2. Ubungane bemvelo benqubo yokukhiqiza
Inqubo yokukhiqiza yesikhwama se-EVA nayo inomthelela obalulekile ebunganeni bayo bemvelo. Inqubo yokukhiqiza ihlanganisa izinyathelo ezifana nokulungiswa kwempahla eluhlaza, ukubumba kokucindezela okushisayo, nokuphrinta. Kulezi zinqubo, kufanele kusetshenziswe ubuchwepheshe nezindlela ezihambisana nemvelo ukuze kuncishiswe ukusetshenziswa kwamandla kanye nokuphehla imfucuza. Isibonelo, ukulawula izinga lokushisa ngesikhathi sokucindezela okushisayo kubalulekile ekongeni amandla kanye nokunciphisa ukukhishwa kwemfucuza.
3. Ukwelashwa nokugaywa kabusha
Ukuhlolwa kokufaneleka kwemvelo kwenqubo yokukhiqiza izikhwama ze-EVA nakho kudinga ukucatshangelwa kokuphathwa kwemfucuza kanye nezinyathelo zokugaywa kabusha. Imfucuza ekhiqizwa ngesikhathi sokukhiqiza kufanele igaywe kabusha ngangokunokwenzeka ukuze kuncishiswe umthelela emvelweni. Isibonelo, ukukhishwa nokuphathwa “kwemfucuza emithathu” yedivayisi ye-EVA, okuhlanganisa nokuphathwa kwamanzi angcolile, igesi engcolile kanye nemfucumfucu eqinile, kufanele kuhlangabezane nezidingo zokuvikela imvelo.
4. Ukuhlolwa Komjikelezo Wempilo (LCA)
Ukuqhuba ukuhlolwa komjikelezo wokuphila (LCA) kuyindlela ebalulekile yokuhlola ukusebenza kwemvelo kwezikhwama ze-EVA. I-LCA ihlola ngokuphelele umthelela wayo yonke inqubo yokupakisha endaweni ezungezile kusukela ekuqoqweni kwezinto ezingavuthiwe, ukukhiqizwa, ukusetshenziswa ukumosha ukwelashwa. Nge-LCA, singaqonda umthwalo wemvelo wezikhwama ze-EVA kuwo wonke umjikelezo wabo wokuphila futhi sithole izindlela zokunciphisa umthelela wendawo.
5. Amazinga emvelo kanye nezitifiketi
Ukukhiqizwa kwezikhwama ze-EVA kufanele kulandele izindinganiso zemvelo zasekhaya nezamazwe ngamazwe, njengamazinga kazwelonke e-GB/T 16775-2008 “Polyethylene-vinyl acetate copolymer (EVA) imikhiqizo”
kanye ne-GB/T 29848-2018, ecacisa izidingo zezakhiwo ezibonakalayo, izakhiwo zamakhemikhali, ubuchwepheshe bokucubungula nezinye izici zemikhiqizo ye-EVA. Ngaphezu kwalokho, ukuthola isitifiketi semvelo, njengesitifiketi se-ISO 14001 sohlelo lokuphathwa kwemvelo, kuphinde kube yisithenjwa esibalulekile sokuhlola ubungane bemvelo benqubo yokukhiqiza izikhwama ze-EVA.
6. Ukusebenza komkhiqizo nokuvumelana nezimo zemvelo
Izikhwama ze-EVA kufanele zibe nezakhiwo ezinhle zomzimba, izakhiwo ezishisayo, izakhiwo zamakhemikhali kanye nokuvumelana nezimo zemvelo. Lezi zidingo zokusebenza ziqinisekisa ukuthi isikhwama se-EVA singakwazi ukugcina umsebenzi waso ngesikhathi sokusetshenziswa, kuyilapho sikwazi ukwehlisa noma ukugaywa kabusha endaweni yemvelo ukuze kuncishiswe umthelela emvelweni.
7. Ukuqwashisa ngemvelo kanye nesibopho senkampani
Okokugcina, ukuqwashisa ngemvelo kanye nesibopho somphakathi samabhizinisi nakho kuyizici ezibalulekile ekuhloleni ubungane bemvelo benqubo yokukhiqiza izikhwama ze-EVA. Amabhizinisi kufanele athuthukise ukuqwashisa kwawo ngokuvikelwa kwemvelo nokuzibophezela komphakathi futhi akhuthaze intuthuko esimeme. Ngendlela ye-EVA eluhlaza, amabhizinisi angathuthukisa ukusebenza kwawo ngenkathi enaka ukuvikelwa kwemvelo
Kafushane, ukuhlola ukuthi ingabe inqubo yokukhiqiza yesikhwama se-EVA ihambisana ngempela nemvelo kudinga ukucatshangelwa okuphelele kwezici eziningi ezifana nezinto ezingavuthiwe, izinqubo zokukhiqiza, ukulashwa kwemfucuza, ukuhlola umjikelezo wokuphila, izindinganiso zemvelo, ukusebenza komkhiqizo kanye nesibopho senkampani. Ngalezi zinyathelo, singaqinisekisa ukuthi inqubo yokukhiqiza yezikhwama ze-EVA ihlangabezana nezidingo zokuvikelwa kwemvelo futhi ibambe iqhaza ekuvikeleni imvelo.
