Cov ntsiab lus qauv ntawm D4, D5, thiab D6 hauv kev tshuaj ntsuam luam ntawv silicone

Cov txheej txheem cov ntsiab lus ntawm D4, D5, thiab D6 hauv kev tshuaj ntsuam luam ntawv silicone sib txawv vim muaj kev cai tswj hwm hauv ntau lub teb chaws thiab cheeb tsam thiab cov xwm txheej sib txawv:
EU: Raws li kev cai REACH, txij lub Ib Hlis 31, 2020, cov ntsiab lus ntawm D4 thiab D5 hauv cov tshuaj pleev ib ce yog txwv tsawg dua 0.1% (w/w); Txij Lub Rau Hli 6, 2026, D4, D5, thiab D6 yuav tsum tsis txhob siv los ua cov tshuaj ntxuav kom qhuav rau cov ntaub ntawv, tawv, thiab cov plaub, tshwj tsis yog tias D5 yog siv los ua cov kuab tshuaj ntxuav cov ntaub, tawv, thiab pluab hauv kev tswj xyuas nruj kaw kom qhuav. systems, thiab cov kuab tshuaj ntxuav yog siv los yog incinerated.
Tuam Tshoj: Tam sim no tsis muaj cov qauv qhia meej thiab sib koom ua ke rau cov ntsiab lus ntawm D4, D5, thiab D6 hauv kev tshuaj ntsuam luam ntawv silicone, tab sis cov qauv ntawm qee cov khoom lag luam muaj feem cuam tshuam nrog kev txwv tsis pub muaj cov organic sib xyaw ua ke, thiab lwm yam, uas cuam tshuam ncaj qha rau kev tswj cov ntsiab lus. Cov tshuaj no hauv kev tshuaj ntsuam luam ntawv silicone. Piv txwv li, nyob rau hauv ib puag ncig tus phooj ywg silk-screen silicone cov khoom, manufacturers yuav tswj cov ntsiab lus ntawm cov khoom xws li D4, D5, thiab D6 kom tau raws li cov kev cai tiv thaiv ib puag ncig.
Cov qauv kev lag luam: Qee lub tuam txhab yuav xa mus rau qee cov qauv kev lag luam lossis cov lus qhia tshwj xeeb thaum tsim silk-screen silicone. Piv txwv li, Xin'an patented system thiab txoj kev tshem tawm volatiles los ntawm methyl vinyl silicone roj hmab tuaj yeem txo cov volatiles tsawg dua 0.75wt%, thiab cov ntsiab lus ntawm txhua yam khoom ntawm D4, D5, thiab D6 kom tsawg dua { {6}}.25 wt%.
