Yintoni i-eco-leather?

I-Eco-leather yimveliso yesikhumba enezalathi zendalo ezihlangabezana neemfuno zemigangatho yendalo. Yenziwe ngesikhumba sokwenziwa ngokutyumza inkunkuma yesikhumba, inkunkuma kunye nesikhumba esilahliweyo, kwaye emva koko wongeza izinto zokuncamathelisa kunye nokucinezela. Kukwisizukulwana sesithathu seemveliso. I-Eco-leather idinga ukuhlangabezana nemigangatho ebekwe ngurhulumente, kubandakanywa izinto ezine: i-formaldehyde yamahhala, umxholo we-chromium ene-hexavalent, i-azo dyes evaliweyo kunye nomxholo we-pentachlorophenol. 1. I-formaldehyde yasimahla: Ukuba ayisuswanga ngokupheleleyo, iya kubangela umonakalo omkhulu kwiiseli zabantu kwaye ibangele nomhlaza. Umgangatho ngulo: umxholo ungaphantsi kwe-75ppm. 2. Hexavalent chromium: I-Chromium inokwenza ulusu luthambe kwaye lunwebe. Ikho ngeendlela ezimbini: i-chromium ene-trivalent kunye ne-hexavalent chromium. I-Trivalent chromium ayinabungozi. Ichromium enehexavalent egqithisileyo inokonakalisa igazi lomntu. Umxholo kufuneka ube ngaphantsi kwe-3ppm, kwaye i-TeCP ingaphantsi kwe-0.5ppm. 3. I-azo dyes evaliweyo: I-Azo yidayi yokwenziwa evelisa i-amines enuka kamnandi emva kokudibana nolusu, obangela umhlaza, ngoko ke le dayi yokwenziwa ayivumelekanga. 4. Umxholo wePentachlorophenol: Yinto ebalulekileyo yokulondoloza, inetyhefu, kwaye inokubangela ukukhubazeka kwebhayoloji kunye nomhlaza. Umxholo wale nto kwiimveliso zesikhumba umiselwe ukuba yi-5ppm, kwaye umgangatho ongqongqo kukuba umxholo unokuba ngaphantsi kwe-0.5ppm.
