Thaum Lub Ob Hlis 29, 2024, European Pawg Neeg Saib Xyuas Kev Sau Npe, Kev Ntsuam Xyuas, Kev Tso Cai thiab Kev Txwv Cov Tshuaj (REACH) tau pov ntawv pom zoo ib daim ntawv thov kom txwv tsis pub perfluorohexanoic acid (PFHxA), nws cov ntsev, thiab lwm yam tshuaj nyob rau hauv Appendix XVII ntawm REACH txoj cai.
1. Hais txog PFHxA, nws cov ntsev, thiab lwm yam tshuaj
1.1 Cov ntaub ntawv xov xwm
Perfluorohexanoic acid (PFHxA) thiab nws cov ntsev thiab lwm yam tshuaj xa mus rau:
Cov tshuaj sib xyaw nrog perfluoroapentyl pawg txuas rau ncaj los yog ceg C5F11 carbon atoms
Muaj ncaj los yog ceg C6F13 perfluorohexyl pawg
1.2 Tsis suav nrog cov khoom hauv qab no:
C6F14
C6F13-C (=O) OH, C6F13-C (=O) OX ′ lossis C6F13-CF2-X ′ (qhov twg X ′ = tej pab pawg ua haujlwm, suav nrog ntsev)
Txhua yam khoom siv nrog perfluoroalkyl C6F13- ncaj qha txuas nrog sulfur atoms
1.3 txwv kev xav tau
Nyob rau hauv homogeneous cov ntaub ntawv:
PFHxA thiab nws cov ntsev sum: ＜ 0.025 mg/kg
Tag Nrho PFHxA cov tshuaj muaj feem xyuam: ＜ 1 mg / kg
2. Tswj tau
Hluav taws kub sib ntaus ua npuas ncauj thiab hluav taws tua hluav taws ua npuas ncauj tsom rau kev tua hluav taws rau pej xeem, kev cob qhia thiab kev sim: 18 lub hlis tom qab cov kev cai tau pib siv.
Kev siv pej xeem: textiles, tawv, pluab, khau, sib tov hauv khaub ncaws thiab lwm yam khoom siv; Tshuaj pleev ib ce; Khoom noj khoom haus daim ntawv thiab cov duab los qhia: 24 lub hlis txij li hnub siv cov cai.
Textiles, tawv, thiab plaub nyob rau hauv cov khoom uas tsis yog khaub ncaws thiab lwm yam accessories rau pej xeem siv: 36 lub hlis txij li hnub siv cov kev cai.
Civil aviation hluav taws tua hluav taws ua npuas ncauj thiab hluav taws kub sib ntaus ua npuas ncauj mloog zoo: 60 lub hlis tom qab cov kev cai pib siv.
PFHxAs yog ib hom perfluorinated thiab polyfluoroalkyl compound (PFAS). PFHxA cov tshuaj raug suav hais tias muaj kev pheej hmoo thiab fluidity. Lawv tau siv dav hauv ntau qhov kev lag luam, xws li cov ntawv thiab cov ntaub ntawv (cov ntaub ntawv sib cuag cov khoom noj), textiles xws li cov khoom siv tiv thaiv tus kheej, tsev textiles thiab khaub ncaws, thiab hluav taws ua npuas ncauj. EU txoj kev txhim kho kom ruaj khov rau cov tshuaj muab PFAS txoj cai nyob rau pem hauv ntej thiab nruab nrab. Cov European Commission tau cog lus tias yuav maj mam tshem tawm tag nrho PFAS thiab tsuas yog tso cai rau lawv siv nyob rau hauv cov xwm txheej uas nws tau raug pov thawj tias tsis tuaj yeem hloov pauv thiab tseem ceeb rau zej zog.
BTF Testing Lab yog nruab nrog cov kws tshaj lij thiab ua tiav cov chaw sim, pab pawg paub txog kev sim thiab cov kws tshaj lij, thiab muaj peev xwm los daws ntau yam teeb meem kev sim thiab ntawv pov thawj. Peb ua raws li cov qauv qhia ntawm "kev ncaj ncees, kev ncaj ncees, kev ncaj ncees, thiab kev nruj" thiab ua raws li cov cai ntawm ISO/IEC 17025 kev ntsuam xyuas thiab ntsuas qhov ntsuas qhov ntsuas rau kev tswj xyuas kev tshawb fawb. Peb tau cog lus los muab cov neeg siv khoom nrog cov kev pabcuam zoo tshaj plaws. Yog tias koj muaj lus nug, thov koj xav tiv tauj peb txhua lub sijhawm.
