ENF Vs E0 Vs E1: Phau Ntawv Qhia Tag Nrho Rau Txiaj Ntsig Environmental Standards

Txee ib puag ncig cov qauv xa mus rau cov kev cai lossis cov ntawv pov thawj uas qhia txog qib kev tso cai ntawm formaldehyde emissions los ntawm ntoo-raws li cov khoom xws li plywood, MDF, particleboard, thiab laminates. Formaldehyde yog volatile organic compound (VOC) feem ntau siv los ua cov ntaub nplaum hauv cov nplaum thiab cov resins rau cov khoom siv ntoo. Txawm hais tias qhov tseem ceeb rau cov khoom muaj zog, ntau tshaj formaldehyde emissions tuaj yeem ua rau huab cua zoo hauv tsev thiab ua rau muaj kev phom sij rau kev noj qab haus huv.
Cov neeg tsim khoom ua raws li cov qauv tshwj xeeb los txwv cov formaldehyde emissions, ua kom muaj kev nyab xeeb nyob hauv tsev thiab txhawb cov khoom zoo.

1. ENF Txuj
ENF yog ib lo lus tsawg dua tab sis feem ntau hais txog formaldehyde emissions kuaj raws li European Norm (EN) cov qauv. Cov qauv European yog nruj heev thiab feem ntau suav nrog cov kev sim xws li EN 717-1 thiab EN 717-2 rau formaldehyde emissions. Cov khoom lag luam nyob rau hauv ENF kuaj feem ntau ua tau raws li kev txwv tsis pub tshaj tawm, kom ntseeg tau tias VOC tso tawm tsawg.
Txawm hais tias ENF yog ib lub ntsiab lus dav dav, nws feem ntau cuam tshuam rau qhov chaw kuaj qhov chaw emissions ntsuas hauv milligrams ib liter (mg / L) lossis milligrams ib cubic meter (mg / m³) raws li European cov cai.

2. E0 Txuj
Tus qauv E0 sawv cev rau * qis tshaj * formaldehyde emission theem ntawm peb thiab suav tias yog qhov zoo tshaj plaws rau huab cua hauv tsev. Cov khoom lag luam sau npe E0 tawm formaldehyde ntawm qib qis dua 0.5 mg / L lossis 0.5 mg / m³, nyob ntawm txoj kev kuaj.
E0- qib txee yog qhov zoo tagnrho rau qhov chaw uas huab cua tsis zoo yog qhov tseem ceeb tshaj - xws li cov menyuam yaus chav, chaw kho mob, thiab vaj tsev ntsuab. Cov qauv no, nrov nyob rau sab hnub tuaj Asia thiab qee lub tebchaws nyob sab Europe, qhia txog zero formaldehyde emissions, txo cov kev pheej hmoo ntawm kev noj qab haus huv zoo li ua pa ua pa, mob taub hau, thiab ua xua.

3. E1 Txuj
E1 yog cov qauv formaldehyde emission ntau tshaj plaws uas yuav tsum tau muaj nyob hauv ntau lub tebchaws, suav nrog Tebchaws Europe, Tebchaws Asmeskas, thiab thaj chaw ntawm Asia. Nws txwv formaldehyde emissions kom qis dua 1.5 mg / L lossis 1.5 mg / m³.
Thaum E1-qib txee txee yuav muaj cov pa tawm formaldehyde ntau dua li E0, nws tseem ua raws li tsoomfwv cov cai thiab feem ntau muaj kev nyab xeeb rau kev siv vaj tse thiab kev lag luam. Cov qauv no yog suav tias yog tus qauv ntsuas rau ntsuas tus nqi thiab kev nyab xeeb, ua E1 cov khoom siv dav thiab pheej yig.
