PECOAT® PVC plastisol txheej dhau REACH SVHC kuaj, ua kom pom kev nyab xeeb zoo
PECOAT® PVC plastisol txheej tau ua tiav qhov kev xeem REACH Cov Khoom Muaj Kev Txaus Siab Siab (SVHC) ua los ntawm lub koom haum soj ntsuam thoob ntiaj teb SGS. Txhua qhov ntsuas tau ua tau raws li EU cov qauv nruj, ntxiv qhov tseem ceeb ntawm kev nyab xeeb rau nws daim ntawv thov hauv kev ua lag luam thoob ntiaj teb.
Qhov kev sim ntsuas tag nrho suav nrog cov tshuaj muaj feem cuam tshuam los ntawm European Chemicals Agency (ECHA). Tshwj xeeb, nws tau tshuaj xyuas 250 yam khoom hauv Daim Ntawv Teev Npe Ntawm Cov Khoom Muaj Kev Nyuaj Siab Heev (SVHC) luam tawm los ntawm ECHA rau thiab ua ntej Lub Rau Hli 25, 2025. Tib lub sijhawm, nws kuj tau ua cov ncauj lus kom ntxaws txog tag nrho 6 qhov muaj peev xwm SVHC, suav nrog 1 lub peev xwm SVHC raws li kev txheeb xyuas thiab 5 cov peev xwm SVHC luam tawm los ntawm ECHA.
Nyob rau hauv cov nqe lus ntawm kev xeem txoj kev, SGS nyob rau hauv-lub tsev txoj kev tau txais yuav, thiab ntau yam advanced analytical cov tswv yim xws li Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Ultraviolet-Visible Spectrophotometry (UV-VIS), Gas Chromatography-Mass Spectrometry (GC-MS), High-Perderometry. Ntes/Mass Spectrometry (HPLCDAD/MS), thiab Colorimetric Method tau siv los ua kom paub tseeb qhov tseeb ntawm qhov kev sim.
Cov qhabnias xeem tau qhia tias PECOAT® PVC plastisol txheej ua tau zoo heev. Hauv kev ntsuam xyuas ntawm 250 SVHC cov tshuaj hauv Daim Ntawv Teev Npe, cov ntsiab lus ntawm txhua yam khoom hauv cov qauv yog ≤ 0.1% (qhov hnyav piv), thiab qhov txiaj ntsig tau dhau. Rau 6 cov khoom muaj peev xwm SVHC, lawv cov ntsiab lus hauv cov qauv kuj yog ≤ 0.1% (qhov hnyav piv), thiab lawv kuj dhau qhov kev ntsuam xyuas zoo. Tsis tas li ntawd, tag nrho cov tshuaj ntsuam xyuas tsis raug kuaj pom (ND), txhais tau tias lawv cov ntsiab lus qis dua qhov Kev Tshaj Tawm Tshaj Tawm (RL). RLs ntawm cov khoom sib txawv txawv raws li lawv cov yam ntxwv. Piv txwv li, RLs rau cov khoom xws li cobalt, arsenic, thiab txhuas yog 0.005%, thiab rau molybdenum, nws yog 0.0005%, thiab lwm yam.
Qhov kev xeem no txhais tau tias PECOAT® PVC plastisol txheej ua tiav raws li cov cai ntawm REACH Txoj Cai. Raws li cov kev cai cuam tshuam ntawm REACH Txoj Cai, txij li qhov concentration ntawm cov khoom hauv cov qauv uas ua tau raws li cov qauv teev tseg tsis pub dhau 0.1% (qhov hnyav piv), tsis tas yuav tsum ua cov ntaub ntawv ntxiv thiab kev ceeb toom cov luag haujlwm, thiab tsis tas yuav tsum npaj Daim Ntawv Qhia Kev Nyab Xeeb (SDS) kom ua tau raws li cov khoom siv sib txuas lus. Qhov no tshem tawm txoj hauv kev rau nws txoj kev ncig hauv EU ua lag luam.
Kev xeem dhau ntawm REACH SVHC los ntawm PECOAT® PVC plastisol txheej tsis tsuas yog cuam tshuam PECOAT® kev saib xyuas thiab kev tswj xyuas nruj ntawm cov khoom zoo thiab kev nyab xeeb tab sis kuj qhia nws lub zog hauv kev sib tw ua lag luam thoob ntiaj teb. Rau cov lag luam downstream, siv cov txheej no tuaj yeem txo qhov kev pheej hmoo ntawm kev ua raws cai thiab ua kom cov kev ua tiav ntawm kev tsim khoom. Rau cov neeg siv khoom, nws yog ib qho kev cog lus ntawm kev thaj yeeb ntawm lub siab, txhais tau hais tias cov khoom lag luam uas lawv tau ntsib nrog muaj kev ruaj ntseg tshuaj tiv thaiv kev nyab xeeb.
