Umxholo ongundoqo
Umthetho wokugqibela okhutshwe yi-US Environmental Protection Agency (EPA) phantsi koMthetho woLawulo lweZinto ezinobungozi (TSCA) uqale ukusebenza ngokusesikweni. Lo mthetho uyakwalela ukusetyenziswa kwe-methylene chloride kwiimveliso zabathengi ezifana nee-paint strippers kwaye ubeka imiqathango engqongqo ekusetyenzisweni kwayo kwimizi-mveliso.
Eli nyathelo lijolise ekukhuseleni impilo yabathengi kunye nabasebenzi. Nangona kunjalo, njengoko esi sinyibilikisi sisetyenziswa kakhulu kumashishini amaninzi, siqhuba ngamandla i-R&D kunye nokukhuthazwa kwemarike kwezinyibilikisi ezizezinye ezinobuhlobo nokusingqongileyo—kuquka iimveliso ezilungisiweyo ze-N-methylpyrrolidone (NMP) kunye nezinyibilikisi ezisekelwe kwi-bio.
Impembelelo yoShishino
Ichaphazele ngokuthe ngqo amasimi eemveliso zokususa ipeyinti, ukucoca isinyithi, kunye nezinye izinto ezisetyenziswa ngamayeza, nto leyo enyanzelisa amashishini angaphantsi komlambo ukuba akhawulezise ukutshintsha ifomula kunye nokulungiswa kwekhonkco lokubonelela.
