Okuqukethwe Okubalulekile
Umthetho wokugcina okhishwe ngabe-US Environmental Protection Agency (EPA) ngaphansi komthetho iToxic Substances Control Act (TSCA) usuqalile ukusebenza ngokusemthethweni. Lo mthetho uvimbela ukusetshenziswa kwe-methylene chloride emikhiqizweni yabathengi efana nezihluthulelo zopende futhi ubeka imingcele eqinile ekusetshenzisweni kwayo kwezimboni.
Lesi sinyathelo sihlose ukuvikela impilo yabathengi nabasebenzi. Kodwa-ke, njengoba lesi sincibilikisi sisetshenziswa kabanzi ezimbonini eziningi, siqhuba kakhulu i-R&D kanye nokukhuthazwa kwemakethe kwezinye izinyibilikisi ezihambisana nemvelo—kuhlanganise nemikhiqizo eguquliwe ye-N-methylpyrrolidone (NMP) kanye nezinyibilikisi ezisekelwe ku-bio.
Umthelela Wemboni
Kuthinte ngokuqondile izinkambu zokuhlubula upende, ukuhlanzwa kwensimbi, kanye nabanye abaxhumanisa bezemithi, kuphoqe amabhizinisi angaphansi komfula ukuthi asheshise ukushintsha kwefomula kanye nokulungiswa kochungechunge lokuhlinzeka.
