PECOAT® PVC Kupaka kwa plastisol kumadutsa kuyesa kwa REACH SVHC, kuwonetsa chitetezo chabwino kwambiri
PECOAT® PVC zokutira plastisol adapambana mayeso a REACH Substances of Very High Concern (SVHC) ochitidwa ndi bungwe loyesa padziko lonse lapansi la SGS. Zizindikiro zonse zimakwaniritsa miyezo yolimba ya EU, ndikuwonjezera chitsimikizo chofunikira chachitetezo pakugwiritsa ntchito kwake pamsika wapadziko lonse lapansi.
Kuyesaku kumakhudza mokwanira zinthu zoyenera zofalitsidwa ndi European Chemicals Agency (ECHA). Mwachindunji, idawonetsa zinthu za 250 mu Candidate List of Substances of Very High Concern (SVHC) lofalitsidwa ndi ECHA pa June 25, 2025 komanso pamaso pa June 6, 1. Panthawi imodzimodziyo, idayesanso mwatsatanetsatane pa chiwerengero cha 5 SVHCs, kuphatikizapo XNUMX yomwe ingathe SVHC pansi pa chizindikiritso ndi XNUMX zomwe zingatheke SVHCs zofalitsidwa ndi Intention Lists mu ECHA.
Pankhani ya njira zoyesera, njira zamkati za SGS zidakhazikitsidwa, ndi njira zingapo zowunikira zowunikira monga Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Ultraviolet-Visible Spectrophotometry (UV-VIS), Gas Chromatography-Mass Spectrometry (GC-MS), High-Performance Architecture/Chromatography Spectrometry (HPLCDAD/MS), ndi Colorimetric Method anagwiritsidwa ntchito pofuna kutsimikizira kulondola kwa kuyezetsa.
Zotsatira za mayeso zimasonyeza zimenezo PECOAT® PVC Kupaka kwa plastisol kunachita bwino kwambiri. Poyesa zinthu za 250 SVHC mu Mndandanda wa Otsatira, zomwe zili muzinthu zilizonse zomwe zili mu chitsanzozo zinali ≤ 0.1% (chiŵerengero cha kulemera kwake), ndipo zotsatira zake zidadutsa. Pazinthu za 6 zomwe zingatheke za SVHC, zomwe zili mu chitsanzozo zinalinso ≤ 0.1% (chiŵerengero cha kulemera kwake), ndipo adapambananso mayeso bwino. Kuphatikiza apo, zinthu zonse zoyesedwa sizinapezeke (ND), kutanthauza kuti zomwe zili pansi pa Reporting Limit (RL). Ma RL a zinthu zosiyanasiyana amasiyana malinga ndi mawonekedwe awo. Mwachitsanzo, ma RL a zinthu monga cobalt, arsenic, ndi lead ndi 0.005%, ndipo molybdenum ndi 0.0005%, ndi zina zambiri.
Chotsatira ichi chikutanthauza kuti PECOAT® PVC Kupaka kwa plastisol kumagwirizana kwathunthu ndi zofunikira za REACH Regulation. Malinga ndi zomwe zili mu REACH Regulation, popeza kuchuluka kwa zinthu zomwe zili mu zitsanzo zomwe zimakwaniritsa zomwe zatchulidwazi sikudutsa 0.1% (chiyerekezo cha kulemera), palibe chifukwa chochitira zidziwitso zowonjezera ndi zidziwitso, komanso sikofunikira kukonzekera Tsamba la Chitetezo (SDS) kuti likwaniritse zofunikira zolumikizirana ndi chain chain. Izi zimatsegula njira yoyendetsera msika wa EU.
Kudutsa kwa kuyezetsa kwa REACH SVHC ndi PECOAT® PVC Kupaka kwa plastisol sikungowonetsa PECOATKusamala kwambiri kwa ® ndikuwongolera mosamalitsa zamtundu wazinthu ndi chitetezo komanso kukuwonetsa mphamvu zake pampikisano wamsika wapadziko lonse lapansi. Kwa mabizinesi akumunsi, kugwiritsa ntchito zokutira izi kumatha kuchepetsa ngozi zotsatiridwa ndikuwonetsetsa kuti ntchitoyo ikuyenda bwino. Kwa ogula, ndi lonjezo la mtendere wamaganizo, kutanthauza kuti zinthu zoyenera zomwe amakumana nazo zimakhala ndi chitsimikizo chodalirika cha chitetezo cha mankhwala.
