Kutulutsa kwa Formaldehyde kuchokera ku Composite Wood Products Regulation (SOR/2021-148)

Kutulutsa kwa Formaldehyde kuchokera ku Composite Wood Products Regulations (SOR/2021-148) yovomerezedwa ndi Unduna wa Zachilengedwe komanso Unduna wa Zaumoyo ku Canada ziyamba kugwira ntchito pa Januware 7, 2023.

Werengani choyambirira:

Lamuloli limagwira ntchito pamitengo iliyonse yamitengo yomwe ili ndi formaldehyde.Mipangidwe yambiri yamatabwa yomwe imatumizidwa kunja kapena kugulitsidwa ku Canada iyenera kukwaniritsa malamulowo. ku Canada tsiku logwira ntchito lisanafike silingagwirizane ndi lamuloli malinga ngati pali zolemba zotsimikizira.Malire a Formaldehyde emissions Lamuloli limatchula mlingo waukulu wa kutulutsa kwa formaldehyde wazinthu zamatabwa. Njira (ASTM D6007, ASTM E1333), ndipo ndizofanana ndi malire a EPA TSCA Title VI regulation:

ppm ya plywood yolimba, 0.05 ppm
ppm kwa particleboard, 0.09 ppm,
ppm yapakatikati-kachulukidwe fiberboard, 0.11 ppm
ppm ya fiberboard yocheperako yapakatikati, 0.13 ppm
ppm ya pepala laminated, 0.05ppm

Mitengo yonse ya matabwa iyenera kulembedwa zisanayambe kugulitsidwa ku Canada, kapena wogulitsa ayenera kusunga zolembazo ndikuzipereka nthawi iliyonse. Malamulo a Mutu VI a United States adzaonedwa kuti akugwirizana ndi zofunikira zolembera za Canada. Mitengo yophatikizika ndi zinthu zopangidwa ndi laminated ziyeneranso kutsimikiziridwa ndi gulu lachitatu la certification Authority (TPC) musanatumizedwe kapena kugulitsidwa (zindikirani: zopangidwa ndi matabwa zomwe zili ndi adalandira certification ya TSCA Title VI ivomerezedwa ndi lamuloli).

Zokhudza kuyang'anira zinthu zamatabwa:【Chidziwitso cha QC】 Momwe mungayang'anire zinthu zamatabwa?(ccic-fct.com)

CCIC FCT ngati gulu loyang'anira akatswiri, woyang'anira wathu aliyense mu gulu lathu ali ndi zaka zopitilira zitatu zowunika, ndipo amapambana mayeso athu pafupipafupi.CCIC-FCT ikhoza kukhala mlangizi wanu wowongolera zinthu nthawi zonse.
