PVC qab nthab panels yeej muaj kev ntsuam xyuas ib puag ncig; cov no nyob ntawm cov khoom siv raw thiab cov khoom siv ntxiv uas siv thaum lub sijhawm tsim khoom.
Kev ntsuas ib puag ncig feem ntau yog ntsuas raws li cov qauv ntawv pov thawj thoob ntiaj teb lossis hauv tsev, xws li EU's RoHS thiab REACH, thiab Tuam Tshoj's GB / T 18580-2017. Hauv qab no yog cov lus piav qhia ntxaws txog kev ntsuas ib puag ncig rau PVC qab nthab panels:
Environmental Certification Standards:
RoHS Certification: Feem ntau txwv tsis pub siv cov khoom phom sij xws li txhuas, mercury, thiab cadmium.
REACH Certification: tsom rau kev siv nyab xeeb thiab sau npe ntawm cov tshuaj lom neeg.
GB/T 18580-2017: Tuam Tshoj tus qauv rau formaldehyde emission txwv nyob rau hauv ntoo-raws li panels thiab tiav cov khoom siv rau kho kom zoo nkauj sab hauv.
Environmental Qib Classifications:
Qib E0: Formaldehyde emission Tsawg dua lossis sib npaug ntawm 0.5 mg / L; tus qauv zoo tshaj plaws ib puag ncig.
Qib E1: Formaldehyde emission Tsawg dua lossis sib npaug li 1.5 mg / L; ua tau raws li lub teb chaws tus qauv.
Qib E2: Formaldehyde emission Tsawg dua lossis sib npaug li 5.0 mg / L; xav tau kev kho mob ua ntej siv sab hauv tsev.
