Iyini i-eco-leather?

I-Eco-leather ingumkhiqizo wesikhumba ozinkomba zemvelo ezihlangabezana nezidingo zezindinganiso zemvelo. Kuyisikhumba sokwenziwa esenziwe ngokuchoboza isikhumba sikadoti, izinsalela kanye nesikhumba esilahliwe, bese wengeza izinto ezinamathelayo nokucindezela. Kungokwesizukulwane sesithathu semikhiqizo. I-Eco-leather idinga ukuhlangabezana namazinga abekwe uhulumeni, okuhlanganisa izinto ezine: i-formaldehyde yamahhala, okuqukethwe kwe-chromium ene-hexavalent, odayi be-azo abavinjelwe kanye nokuqukethwe kwe-pentachlorophenol. 1. I-formaldehyde yamahhala: Uma ingasuswa ngokuphelele, izodala umonakalo omkhulu kumangqamuzana omuntu futhi ibangele nomdlavuza. Izinga lithi: okuqukethwe kungaphansi kuka-75ppm. 2. I-chromium ene-hexavalent: I-Chromium ingenza isikhumba sithambe futhi sinwebeke. Itholakala ngezindlela ezimbili: i-chromium eyi-trivalent ne-hexavalent chromium. I-trivalent chromium ayinabungozi. I-chromium ene-hexavalent eyeqile ingalimaza igazi lomuntu. Okuqukethwe kufanele kube ngaphansi kuka-3ppm, futhi i-TeCP ibe ngaphansi kuka-0.5ppm. 3. Amadayi e-azo avinjelwe: I-Azo iyidayi yokwenziwa ekhiqiza ama-amine anephunga elimnandi ngemva kokuxhumana nesikhumba, okubangela umdlavuza, ngakho-ke lo dayi wokwenziwa awuvunyelwe. 4. Okuqukethwe kwe-Pentachlorophenol: Kuyisilondolozi esibalulekile, kunobuthi, futhi kungabangela ukukhubazeka kwezinto eziphilayo kanye nomdlavuza. Okuqukethwe kwale nto emikhiqizweni yesikhumba kubalulwe ukuthi kube ngu-5ppm, futhi indinganiso eqinile ukuthi okuqukethwe kungaba ngaphansi kuka-0.5ppm kuphela.
