Ndanga ndichida kuita chidimbu papurasitiki e-waste kwenguva yakati ikozvino. Izvi zvinodaro nekuti ndakaita huwandu hwakanaka hwepurasitiki e-waste kutengesa gore rapfuura. Ini ndinotenga makomputa ane baled nemakesi eterevhizheni kubva kuUnited States ndozvipinza muChina kuti zvitengese uye kugovera.
Plastic e-waste, dzimwe nguva inonzi "e-plastic," inoumbwa nepurasitiki yakabviswa kubva mumidziyo yemagetsi yakadai semakombiyuta, mamonita, nhare, nezvimwewo. Wadii kungokuya nekunyungudusa e-plastiki pamwe chete woidzorera zvakare kuita midziyo yemagetsi?
Heino dambudziko, mae-plastiki asati anyungudutswa oshandurwa kuita resin yepurasitiki yakadzokororwa, inofanira kutanga yapatsanurwa kuita mhando yepurasitiki. Plastic e-waste inowanzoumbwa nemhando dzinotevera: ABS, ABS (flame-retardant), ABS-PC, PC, PS, HIPS, PVC, PP, PE, nezvimwewo. Imwe neimwe mhando yepurasitiki ine yayo yekunyungudika uye zvivakwa uye haigone kusanganiswa pakugadzira chigadzirwa.
Saka mubvunzo ikozvino ndewekuti, tinoparadzanisa sei zvese?
Nepo zvinhu zvichiitwa zvakasiyana chaizvo muUnited States (zvichida zveotomatiki nekuda kwemuhoro wakakwira), ndakaita rombo rakanaka rekushanyira e-plastiki yekuparadzanisa chirimwa pano muShanghai, China uko zvinhu zvakawanda zvinoitwa nemaoko.
Sekureva kwemuridzi wenzvimbo iyi, mazhinji e-e-plastiki maitiro echirimwa anotengeswa kubva kunyika dzeEurope neUnited States. Unhu hwepurasitiki kubva kunyika idzi, sehuwandu, huri nani.
Kana ndichitaura zvemanyorero, ndinoreva chaizvo! Nhanho yekutanga mupurasitiki e-waste separation ndeyekurongedza zvidimbu zvakakura nemaoko nenyanzvi dzinogona kusiyanisa pakati pe7-10 mhando dzepurasitiki nekungotarisa, kunzwa, nekupisa. Panguva imwecheteyo, vashandi vanofanira kubvisa chero simbi (kureva, screws), mabhodhi edunhu, uye waya dzakawanikwa. Nyanzvi dzinokurumidza kukurumidza uye dzinogona kurongedza kuburikidza ne500KG kana kupfuura pazuva.
Ndakabvunza muridzi wezvinhu zvese izvi. Akapindura nekuzvikudza achiti, "kurongeka kwacho kunosvika 98%, dai zvisina kudaro, ndingadai ndisina vatengi vanotenga zvinhu zvangu ..."
Kana zvimedu zvakakura zvaparadzaniswa, zvinoiswa kuburikidza nekucheka uye rinsing apparatus. Maflakisi epurasitiki anoguma anoomeswa nezuva uye akagadzirira kuiswa.
Kune zvidimbu zvidiki zve-e-plastiki zvisingagoni kuparadzaniswa nemaoko, zvinoiswa mumabhabhu akati wandei emakemikari ekugezera ane salinity yakasiyana. Kubva zvandinonzwisisa, imwe yemidziyo ine mvura chete. Nekuda kweiyo densities, PP uye PE mapurasitiki anozogara achiyangarara kumusoro. Izvi zvinobviswa uye zvinoiswa padivi.
Plastiki riri pasi rinobva rakwizwa roiswa mune rimwe tabhu rine munyu wakasiyana-siyana, zvinhu zvokuchenesa, nemamwe makemikari. Iyi nzira inodzokororwa kusvikira mamwe mapurasitiki arongwa.
