PFHxA ichaverengerwa muREACH kutonga kutonga

Musi waFebruary 29, 2024, European Committee on Registration, Evaluation, Licensing and Restriction of Chemicals (REACH) vakavhota kuti vabvumire chirevo chekurambidza perfluorohexanoic acid (PFHxA), munyu wayo, uye zvinhu zvine hukama muAppendix XVII yemutemo weREACH.
1. Nezve PFHxA, munyu wayo, uye zvinhu zvinoenderana
1.1 Ruzivo rwezvinhu
Perfluorohexanoic acid (PFHxA) nemunyu wayo uye zvinhu zvine hukama zvinoreva:
Macompound ane perfluoroapentyl mapoka akabatana kune yakatwasuka kana branched C5F11 kabhoni maatomu.
Kuve yakatwasuka kana branched C6F13 perfluorohexyl mapoka
1.2Tisingasanganisire zvinhu zvinotevera:
C6F14
C6F13-C (=O) OH, C6F13-C (=O) OX ′ kana C6F13-CF2-X ′ (uko X ′=chero boka rinoshanda, kusanganisira munyu)
Chero chinhu chine perfluoroalkyl C6F13- chakabatana zvakananga nemaatomu esarufa
1.3Gadzirisa zvinodiwa
Mune homogeneous zvinhu:
PFHxA nehuwandu hwayo hwemunyu: ＜ 0.025 mg/kg
Yese PFHxA ine hukama zvinhu: ＜ 1 mg/kg
2. Kudzora chiyero
Furo rekudzimisa moto uye furo rekudzimisa moto rinonangana neveruzhinji kurwira moto, kudzidziswa uye kuyedzwa: Mwedzi gumi nemasere mushure mekunge mirau yatanga kushanda.
Zvekushandiswa neveruzhinji: machira, matehwe, makushe, shangu, musanganiswa muzvipfeko nezvimwe zvine chekuita; Cosmetics; Pepa rekubata chikafu uye kadhibhodhi: Mwedzi makumi maviri nemana kubva pazuva rekushanda remirairo.
Machira, matehwe, uye mvere mune zvigadzirwa kunze kwembatya uye zvine hukama zvishandiso zvekushandiswa neveruzhinji: Mwedzi makumi matatu nematanhatu kubva pazuva rekushanda remitemo.
Civil aviation fire fighting furo uye fire fight foam concentrate: 60 mwedzi mushure mekunge mitemo yatanga kushanda.
PFHxAs imhando yeperfluorinated uye polyfluoroalkyl compound (PFAS). PFHxA zvinhu zvinoonekwa sekushingirira uye kuyerera. Iwo anoshandiswa zvakanyanya mumaindasitiri mazhinji, akadai semapepa nemapepa (chikafu chekubata zvinhu), machira senge zvekuzvidzivirira nazvo, machira epamba uye zvipfeko, uye furo remoto. Iyo EU's sustable development strategy yemakemikari inoisa PFAS mutemo kumberi nepakati. European Commission yakazvipira kubvisa zvishoma nezvishoma kunze kwePFAS yese uye kungobvumira kushandiswa kwavo mumamiriro ezvinhu uko kunoratidzwa kuve isingadzoreki uye kwakakosha kunharaunda.
BTF Testing Lab yakashongedzerwa nehunyanzvi uye yakakwana yekuyedza zvivakwa, timu ine ruzivo yekuyedza uye nyanzvi dzezvitupa, uye kugona kugadzirisa kwakasiyana kwakaoma kuyedzwa uye matambudziko etifiketi. Isu tinoomerera kune inotungamira misimboti ye "kurongeka, kusarerekera, kurongeka, uye kuomarara" uye tinonyatso kutevedzera zvinodiwa ne ISO/IEC 17025 yekuyedza uye calibration laboratory manejimendi system yekutonga kwesainzi. Takazvipira kupa vatengi basa remhando yepamusoro. Kana uine mibvunzo, ndapota inzwa wakasununguka kutibata nesu chero nguva.
