Kutshanje, intatheli ifunde kuMbutho wePhepha laseChina, ngokutsho kweChina Paper Association yonyaka, umbutho uye wagqiba "akukho ndebe yeplastiki yephepha (kubandakanywa akukho plastiki.iikomityi zephepha ezinokonakala)” uyilo lomgangatho weqela, ngoku ukuze uluntu lufune izimvo.
Intoniiikomityi zephepha ezivundisiweyoayikho ikomityi yephepha yeplastiki?Yintoni umahluko phakathi kwayo kunye ne-aiikomityi zephepha ezenzelwe wena?
Abathengi abaninzi basenokungazi ukuba iikomityi zabo zesiqhelo ezilahlwayo zibonakala ngathi zinobuhlobo kakhulu nokusingqongileyo, kodwa zezodidi olungenakuphinda lusetyenziswe kuluhlu lwenkunkuma.
"Iikomityi zephepha zisikelwe umda yimveliso yephepha ayizizo iimpawu zokungangeni kwamanzi, ukuze kuthintelwe ukuphuma kwamanzi, ifilimu egqunywe ngeplastiki ye-polyethylene (PE) iya kongezwa kwiikomityi zephepha." Ngokweshishini lokupakisha iplastiki eHaikou, eHainan, kushushu. Isiselo esibandayo siya kuqatywa ngaphakathi nangaphandle kwendebe.Akulula ukuhlukana nephepha kwinkqubo yokuphinda isetyenziswe, ngoko ihlukaniswe ibe yinkunkuma engenakuphinda isetyenziswe.
Kuyaqondwa ukuba ukusukela nge-1 kaDisemba, i-Hainan ebanzi "yeplastiki yokuvalwa", ifakwe kwiphondo laseHainan ivaliwe imveliso kunye nokusetyenziswa kwentengiso yoluhlu lweemveliso zeplastiki ezilahlwayo ezingaboliyo (ibhetshi yokuqala) yeemveliso zeplastiki ziya kuvala ukuveliswa kunye nokuthengisa, inkampani. uphando kunye nophuhliso oluveliswe ngokutyabeka emanzini endaweni yekomityi yemveli yephepha le-polyethylene yokwaleka ngaphandle kwekomityi yephepha leplastiki, qaphela yonke i-biodegradation.
Ingaba ikomityi yephepha leplastiki eveliswe lishishini ifanelekile ngumgangatho.Uyilo lwekomityi yephepha leplastiki (kubandakanywa akukho phepha leplastiki yekomityi yephepha) lichaza ukuba " iikomityi zesiseko zephepha kufuneka zihlangabezane neemfuno ze-QB / T 4032. Ioli emhlophe iya kuhlangabezana neemfuno ze-GB 1886.215.I-inki kunye ne-adhesive iya kuhambelana nemigangatho efanelekileyo.Izongezo ezisetyenziswa kwiikomityi zephepha, ioyile emhlophe, i-inki, izinto zokuncamathelisa kunye neengubo ezisekwe emanzini kufuneka zihlangabezane neemfuno ze-GB 9685.
Ngokwentshayelelo, ikomityi yephepha eqhelekileyo elahlwayo ngenxa yokuba iqulethe i-polyethylene, eneneni ayinakuphinda isetyenziswe, ingelulo uhlobo lokhuseleko lokusingqongileyo oluyimfuneko yemihla ngemihla.Nangona iikomityi zephepha ezigqunywe ngePLA zinokubola ngokupheleleyo, ixabiso eliphezulu lezinto ezikrwada likhokelela kwixabiso eliphezulu leemveliso ezigqityiweyo.Ngokukhuthazwa "kokuvalwa kweengxowa zeplastiki", akukho zikomityi zephepha zeplastiki ezavelayo.
Kuyaqondwa ukuba "i-plastic ban" iqulethe i-polyethylene, i-polypropylene, i-polystyrene, i-polyvinyl chloride, i-polyvinyl chloride-vinyl acetate copolymer, i-polyethylene terephthalate kunye nezinye izinto ze-polymer ezingenayo i-biodegradable zemveliso yeplastiki enye.
“Kumenzi wekomityi yephepha, ukuba unokufumana into enexabiso eliphantsi ehlangabezana neemfuno zokusebenza zekomityi yephepha kwaye ingeyiyo enye yezinto ezintandathu ezingaboliyo, ke ikomityi yakhe yephepha inokubizwa ngokuba ziikomityi zephepha zeplastiki kwaye ibekwe emarikeni. .” Iingcali zixelele iintatheli.
Ukongeza, inokwaziswa ngokuhambelana nokuba i-coating is degradable ayisayi kuba yikomityi yephepha leplastiki ehlelwe ngokufanelekileyo kwiindidi ezimbini, ezizezi, "ikomityi yephepha yokugquma engaboliyo" kunye "nekomityi yephepha ebolileyo".Kwixesha langaphambili, ngokude nje ukuba izithako zokugqoka zingabandakanyi kuluhlu lwangoku lwezinto ezingabonakaliyo, zisenokuziswa ngokusemthethweni kwiimarike.
Njengoko itekhnoloji ihambela phambili, ithemba lelokuba izinto ezinexabiso eliphantsi ezikwazi ukubola ziya kufumaneka, abantu batsho.
