Dhammaan macluumaadka ku jira qaybta "Dhicisyada" soo socda waxaa laga soo ururiyay EWPAA: Ogeysiis Farsamo, Formaldehyde Emissions ee Plywood iyo Laminated Veneer Lumber.
Qaybtani waxa ay tixraacaysaa wershadaha sii socda ee tijaabinta balaadhan ee qiiqa formaldehyde ee alaabta summadaha leh ee EWPAA, iyada oo soo koobaysa sahanka ay dhamaystirtay EWPAA ee ku sii daaya Nooca A Alaabooyinka Xidhan, oo leh xabag phenolic ah, ayaa ka dhigan in ka badan 90% wax soo saarka EWPAA kaas oo si wax ku ool ah u leh qiiqa eber.
Formaldehyde
Formaldehyde waa gaas aan midab lahayn, ur xoog leh oo si dabiici ah uga dhex dhaca deegaanka waxaana sii daaya hababka ay ka midka yihiin suuska, gubashada iyo si dabiici ah dhammaan noocyada alwaaxyada.
Formaldehyde Emissions
Plywood waxaa loo soo saaray laba nooc oo dhejis ah oo aasaasi ah: Phenol Formaldehyde (PF) iyo caaga amino, oo ay ku jiraan Melamine Urea Formaldehyde (MUF) iyo Urea Formaldehyde (UF).
Farqi weyn ayaa u dhexeeya kimisteriga labada nooc ee xabagta. Alaabooyinka ku xidhan PF, ka dib hadhaaga formaldehyde heerka hoose ee habka wax soo saarka uu ku bakhtiyo dhowr maalmood gudahood, ma sii daayaan formaldehyde.
Xabagta PF, oo lagu aqoonsan karo midabkeeda madow, waxaa lagu magacaabaa Nooca A ee hoos yimaada heerarka Australiya iyo New Zealand sida loo isticmaalo soo saarista alwaax qaabaysan, alaabada alwaaxa badda ee dibadda (Nooca A).
Labada Yurub iyo Maraykanka, alaabooyinka ku xidhan xabagta PF ayaa loo kala saaray inay yihiin kuwo aan sii dayn oo laga dhaafay shuruucda qiiqa formaldehyde.
Alaabooyinka balaastigga ah ee Amino waxay u muuqdaan inay leeyihiin heerar sare oo formaldehyde ah oo lacag la'aan ah waxayna soo dayn karaan heerar hoose oo formaldehyde ah.
Gabagabada Farsamada Ogeysiiska
Sii daynta formaldehyde ee alaabta shahaadaysan ee EWPAA aad ayey uga hoosaysaa xad la aqbali karo oo la aqbali karo oo ay qeexday Goobta Shaqada Australia mana ka dhigna khatar caafimaad.
Fasalada sii daynta formaldehyde ee Heerarka Australia/New Zealand ayaa ah tafaasiisha shaxda hoose. Alaabooyinka lagu calaamadeeyay fasalada E0 iyo E1 waxay leeyihiin qiiqa formaldehyde oo aad u hooseeya.
