Indlela yokuvavanya ukuba ingaba inkqubo yemveliso yengxowa ye-Eva inobuhlobo ngokwenene nokusingqongileyo?
Kwimeko yanamhlanje yokwandisa ulwazi lokusingqongileyo, kuye kwabaluleke kakhulu ukuvavanya ukuba inkqubo yemveliso yeIingxowa ze-EVAihambelana nokusingqongileyo. Oku kulandelayo luluhlu lwamanyathelo kunye nemigangatho enokusinceda sivavanye ngokubanzi ukulungelelana kokusingqongileyo kwenkqubo yokuvelisa ingxowa ye-EVA.

1. Ubuhlobo bendalo bezinto eziphathekayo
Okokuqala, kufuneka siqwalasele ukuba ingaba izinto eziluhlaza ze-EVA bag zihambelana nokusingqongileyo. Iimathiriyeli ze-EVA ngokwazo aziyiyo ityhefu kwaye azinabungozi kwizinto ezihambelana nokusingqongileyo. Ngexesha lenkqubo yokuvelisa, kufuneka kuqinisekiswe ukuba izinto ze-EVA aziqukethe izinto ezinobungozi kwaye zihambelana nemigangatho efanelekileyo kunye nemimiselo yokusingqongileyo. Ukongeza, imathiriyeli ye-EVA kufuneka ihambelane nemigangatho yamazwe ngamazwe enjengoMyalelo we-RoHS kunye ne-REACH Regulation, ethintela ukusetyenziswa kwezinto ezinobungozi kwaye ifuna ukusetyenziswa ngokukhuselekileyo kweekhemikhali.

2. Ubuhlobo bendalo benkqubo yemveliso
Inkqubo yokuvelisa isikhwama se-EVA nayo inefuthe elibalulekileyo kubungane bayo bendalo. Inkqubo yemveliso ibandakanya amanyathelo afana nokulungiswa kwezinto ezikrwada, ukubumba okushushu, kunye nokushicilela. Kwezi nkqubo, kufuneka kusetyenziswe ubugcisa kunye neendlela ezihambelana nokusingqongileyo ukunciphisa ukusetyenziswa kwamandla kunye nokuveliswa kwenkunkuma. Umzekelo, ukulawulwa kobushushu ngexesha loxinzelelo olushushu lubalulekile ekongeni amandla kunye nokunciphisa ukukhutshwa kwenkunkuma.

3. Ukuphathwa kwenkunkuma kunye nokurisayikilisha
Uvavanyo lokulunga kokusingqongileyo kwenkqubo yokuvelisa ingxowa ye-EVA nayo ifuna uqwalaselo lonyango lwenkunkuma kunye namanyathelo okuhlaziya. Inkunkuma eveliswe ngexesha lenkqubo yokuvelisa kufuneka ihlaziywe kwakhona kangangoko ukunciphisa impembelelo kokusingqongileyo. Ngokomzekelo, ukukhutshwa kunye nokunyangwa "kwenkunkuma emithathu" yesixhobo se-EVA, kubandakanywa nokuphathwa kwamanzi amdaka, igesi engcolileyo kunye nenkunkuma eqinileyo, kufuneka ihlangabezane neemfuno zokukhusela indalo.

4. UVavanyo lweMjikelo woBomi (LCA)
Ukuqhuba uvavanyo lomjikelezo wobomi (LCA) yindlela ebalulekileyo yokuvavanya ukusebenza kokusingqongileyo kweengxowa ze-EVA. I-LCA iphonononga ngokubanzi impembelelo yenkqubo yonke yokupakishwa kokusingqongileyo ukusuka kwingqokelela yezinto ezikrwada, imveliso, ukusetyenziswa kokulahla unyango. Nge-LCA, sinokuqonda umthwalo wokusingqongileyo weengxowa ze-EVA kuwo wonke umjikelo wabo wobomi kwaye sifumane iindlela zokunciphisa impembelelo yokusingqongileyo.

5. Imigangatho yokusingqongileyo kunye nesiqinisekiso
Ukuveliswa kweengxowa ze-EVA kufuneka kulandele imigangatho yasekhaya kunye neyehlabathi jikelele, njengemigangatho yesizwe yaseTshayina GB/T 16775-2008 "imveliso yePolyethylene-vinyl acetate copolymer (EVA)"
kunye ne-GB/T 29848-2018, echaza iimfuno zeempawu ezibonakalayo, iikhemikhali, iteknoloji yokucubungula kunye neminye imiba yeemveliso ze-EVA. Ukongeza, ukufumana isatifikethi sokusingqongileyo, esifana nesatifikethi se-ISO 14001 yenkqubo yolawulo lwendalo esingqongileyo, ikwayireferensi ebalulekileyo yokuvavanya ukulunga kokusingqongileyo kwenkqubo yokuvelisa ibhegi ye-EVA.

6. Ukusebenza kwemveliso kunye nokuguquguquka kokusingqongileyo
Iingxowa ze-EVA kufuneka zibe neempawu ezintle zomzimba, iimpawu zokufudumala, iikhemikhali kunye nokuguquguquka kokusingqongileyo. Ezi mfuno zokusebenza ziqinisekisa ukuba isikhwama se-EVA sinokugcina umsebenzi walo ngexesha lokusetyenziswa, ngelixa likwazi ukuthotywa okanye ukuhlaziywa kwimeko yendalo ukunciphisa impembelelo kwindalo.

7. Ulwazi ngendalo esingqongileyo kunye noxanduva lwequmrhu
Okokugqibela, ulwazi lokusingqongileyo kunye noxanduva lwentlalo lwamashishini zizinto ezibalulekileyo ekuvavanyeni ukulunga kokusingqongileyo kwenkqubo yokuvelisa ingxowa ye-EVA. Amashishini kufuneka aphucule ulwazi lwawo ngokukhuselwa kwendalo kunye noxanduva lwentlalo nokukhuthaza uphuhliso oluzinzileyo. Ngendlela ye-EVA eluhlaza, amashishini anokuphucula ukusebenza kwawo ngelixa enikela ingqalelo ekukhuselweni kwendalo

Isishwankathelo, ukuvavanya ukuba inkqubo yokuvelisa isikhwama se-EVA ihambelana ngokwenene nokusingqongileyo kufuna ukuqwalaselwa ngokubanzi kwezinto ezininzi ezifana nezixhobo eziluhlaza, iinkqubo zokuvelisa, ukuchithwa kwenkunkuma, ukuhlolwa komjikelezo wobomi, imigangatho yokusingqongileyo, ukusebenza kwemveliso kunye noxanduva lwenkampani. Ngala manyathelo, sinokuqinisekisa ukuba inkqubo yokuveliswa kweengxowa ze-EVA ihlangabezana neemfuno zokukhusela okusingqongileyo kunye negalelo ekukhuseleni indalo.
