Intambara hagati y'amacupa y'ibirahure n'amacupa ya plastike ni igihe kirekire, kimara imyaka irenga 60.Hamwe nimpaka zangiza ibidukikije, inyungu zubuzima ningaruka zo kuzirikana, birashobora kugorana guhitamo uwatsinze neza.Ariko ni ubuhe buryo bwiza kuruta ubundi?Reka tumurikire bimwe mubintu byingenzi muriki kibazo.
Ibintu ugomba gusuzuma
Hamwe no kumenyekanisha kumugaragaro amacupa ya pulasitike ahendutse guhera mu myaka ya za 1960, kugabanya umusaruro wamacupa yikirahure byagaragaye.Ibi biterwa no kudashoboka kumeneka, igiciro gito cyumusaruro hamwe nuburyo bworoshye bwamacupa ya plastike.Ugereranije nibirahuri byabo, ibi bituma amacupa ya plastike akundwa cyane.
Vuba aha, icyakora, icyerekezo cyerekeranye nibintu byangiza amacupa ya plastike.Hamwe nimpungenge zimiti ihishe nka BPA, hamwe ningaruka ziherutse kuvumburwa zo gusiga amacupa ya plastike kumurasire yizuba, kureba muri rusange kumacupa ya plastike ntabwo ari byiza rwose.Mugihe ibyinshi mubikoresha plastike ubu ari BPA kubuntu, ibindi bintu byangiza bishobora kubaho bitarashyirwa ahagaragara.
Usibye ububi bwa chimique, ikindi kintu kibi cyaba kwangiriza amacupa ya plastike agira uruhare mubidukikije.Mu mwaka wa 2016, amacupa arenga miliyari 480 y’amacupa yo kunywa ya pulasitike yagurishijwe ku isi yose, aho bitarenze 50% by’amacupa.Guhumanya umusaruro, kubura gutunganya no guta nabi amacupa ya pulasitike bitera ibikomere, ndetse n’urupfu, ku nyamaswa n’ubuzima bwo mu nyanja.Ibi nibintu byose aho ibidukikije biba igitambo cya plastike yubumuntu.
Ntibisobanutse neza
Ariko ikirahuri ni cyiza?Ntabwo ari inyungu zubuzima amacupa yikirahure atanga, hamwe namazi yungurujwe aguma ari meza nta ngaruka zamazi yanduye.Gukaraba no guhagarika amacupa yikirahure mubisanzwe bigira akamaro kuruta amacupa ya plastike.Ubwumvikane rusange ni uko ikirahuri ari ibikoresho byiza kubidukikije, ndetse no kumibiri yacu.Ariko haracyari akaga kubirango, hamwe nibirahure bimenetse kandi byoroshye kumeneka bigira ingaruka zigaragara kumyungu yikigo niba umusaruro uri murwego runini.
Gukora amacupa yikirahure bitera imyuka ya karubone, ntabwo bitandukanye nibyakozwe mumacupa ya plastike.Hariho kandi ikintu cyibanze cyerekana ko ibirahuri byose, nka plastiki, bidasubirwaho.Ibi bivuze ko igipimo cyo gutunganya ibicuruzwa cyongeye kidahagije ugereranije n’ibyangiritse ku musaruro.
Ubwanyuma amacupa yikirahure na plastike byombi bifite ubuzima nibidukikije, ariko ntibivuze ko nabo badafite agaciro.Uratekereza iki?Ese plastiki iruta ikirahure?Cyangwa intsinzi yamacupa ya plastike iracyagaragara? Umusaruro wamacupa yikirahure utera imyuka ya karubone, ntameze nkayakozwe namacupa ya plastike.Hariho kandi ikintu cyibanze cyerekana ko ibirahuri byose, nka plastiki, bidasubirwaho.Ibi bivuze ko igipimo cyo gutunganya ibicuruzwa cyongeye kidahagije ugereranije n’ibyangiritse ku musaruro.

Kandi hagati yicyuma, plastike nikirahure, niyihe nziza?Ukuri kurikibazo nuko hariho ibyiza n'ibibi byo gutunga buri kimwe.
1, Amacupa yicyuma adafite ibyuma byinshi nibibi.Mubisanzwe, bimara igihe kinini kuruta ikirahuri cyangwa plastiki kuko birwanya ruswa, kandi ntibisohora imiti iyo ihuye nizuba / ubushyuhe.Mubisanzwe bihenze kuruta plastiki, kuko ikiguzi cyo kubibyaza umusaruro mwinshi cyane kubera ingufu nyinshi.Nyamara, ibyuma bidafite ingese birashobora gukoreshwa 100 ku ijana.Uburyo bwiza bwo guhitamo amacupa yicyuma nicyiciro cyibiribwa # 304 cyangwa 18/8, bivuze ko hari chromium 18% na nikel 8%.Amakuru yinyongera kumacupa yicyuma arashoborakuboneka kumurongo.
2, Ikirahure nubundi buryo muguhitamoikirahureamacupa.Benshi muritwe tuzi ko hafi ya buri binyobwa biryoha neza mumacupa yikirahure cyangwa igikombe, ariko ikibabaje ni uko bimeneka kandi ntibishobora kumara igihe kinini ugereranije nibyuma bya plastiki cyangwa bitagira umwanda.Mubyongeyeho, igipimo cyo gutunganya ibintu kiri hasi kandi ahantu hamwe na hamwe ntibemerera ibirahuri.Ariko, usibye kuryoherwa nikirahure kinini ntigisohoka mugihe cyizuba / ubushyuhe, ariko ikiguzi cyicupa ryikirahure muri rusange kiri hejuru yandi mahitamo abiri.
3, Plastike isa nkaho icupa ryongeye gukoreshwa cyane, nubwo ikirahure hamwe na stainless bigenda byamamara kubwimpamvu ziri hano.Amacupa ya plastiki ahendutse kubyara kuruta ibyuma nibirahure bidafite ingese, bigatuma bikurura abakiriya.Nyamara, igipimo cyo gutunganya ibintu bimwe na bimwe bya plastiki ni gito kandi ubuzima bwabwo ni bugufi.Amacupa ya plastike akenshi arangirira mumyanda kandi birashobora gufata imyaka 700 mbere yuko bitangira kubora.Imwe mu ngaruka zikomeye ku macupa ya pulasitike ni uko atemba, mu gihe ibirahuri n'ibyuma bitagira umwanda.Bamwe mubakora amacupa yongeye gukoreshwa batanga ibicuruzwa bitarimo iyi miti kandi mubisanzwe berekana ko kuri label cyangwa ikintu ubwacyo.Mubyongeyeho, plastike yakozwe na BPA akenshi izaba ifite code ya resin ya 7 igaragara kubintu.
