Txhawm rau tswj hwm fictdehyde emissions los ntawm plywood, kuv lub teb chaws thiab lwm lub teb chaws tau tsim txoj kev nruj me nyuam ib puag ncig. Piv txwv li:
Lub Tebchaws Txuj Ci: Raws li cov "kev txwv ntawm formaldehyde emissione emissional thiab cov khoom lag luam sab nraud tau muab faib rau E0, E1, thiab E2 Qeb:
- E0: Formaldehyde emissione emission tsawg dua los yog sib luag rau 0.5 mg / u, haum rau cov ntawv thov sab hauv tsev nrog cov qauv kev siv siab.
- E1: Formaldehyde emission emission tsawg dua los yog sib npaug rau 1.5 mg / u, haum rau kev siv sab hauv tsev.
- E2: Formaldehyde emissione emission tsawg dua los yog sib npaug rau 5.0 mg / u, - ventilated ib puag ncig.
Cov Qauv Thoob Ntiaj Teb, xws li European En 13986 tus qauv thiab tus qauv Japanese thiab cov qauv kev kawm qib zoo ib yam li formaldehyde pa tawm.
E0 thiab F ☆☆☆☆ Plywood muaj cov pa tsawg kawg nkaus tsis muaj zog, ua rau kom zoo nkauj rau kev kho kom zoo nkauj thiab cov menyuam yaus lub rooj tog zaum. Tsawg - Cov Plhw Zoo E2-Qib Khoom muaj cov ntsiab lus tseem ceeb dua li ntawm huab cua ua tau zoo.
