Ruzivo rwese mukati meinotevera "Emissions" chikamu chakaunganidzwa kubva kuEWPAA: Technical Note, Formaldehyde Emissions kubva kuPlywood uye Laminated Veneer Lumber.
Ichi chikamu chinoreva kuenderera mberi kweindasitiri kuyedzwa kwakakura kwekubuda kwe formaldehyde kubva kuEWPAA branded zvigadzirwa, muchidimbu ongororo yakapedzwa neEWPAA iyo inoburitsa kubva kuType A Bonded zvigadzirwa, zvine phenolic adhesives, inomiririra pamusoro pe90% yeEWPAA kugadzirwa iyo ine zero emissions.
Formaldehyde
Formaldehyde igasi risina ruvara, rakasimba rinonhuhwirira rinoitika zvakasikwa mukati menharaunda uye rinoburitswa nemaitiro akadai sekuora, kupisa uye zvakasikwa nemarudzi ese ematanda.
Formaldehyde Emissions
Plywood inogadzirwa kune maviri akakosha ekunamira marudzi: Phenol Formaldehyde (PF) uye amino plastiki, iyo inosanganisira Melamine Urea Formaldehyde (MUF) uye Urea Formaldehyde (UF).
Pane misiyano yakakura mumakemikari pakati pemhando mbiri dzekunamatira. Nezvigadzirwa zvakasungwa nePF, mushure mekunge chero yakaderera nhanho yakasara formaldehyde kubva mukugadzira maitiro yaparara mukati memazuva mashoma, haibudisi formaldehyde.
PF inonamira, ichizivikanwa neruvara dema, inodaidzwa kuti Type A pasi peyeAustralia neNew Zealand ply standards sekushandiswa kunoitwa mukugadzira plywood, marine plywood kunze (Type A) zvigadzirwa.
MuEurope neUnited States, zvigadzirwa zvakasungwa nePF zvinonamira zvinoiswa sezvisingabudise uye hazvibvumidzwe kubva kune formaldehyde emission mirau.
Amino mapurasitiki akasungwa zvigadzirwa zvinowanzove nepamusoro zvakasara zvemahara formaldehyde mazinga uye zvinogona kuburitsa yakaderera mwero we formaldehyde.
Technical Note Mhedziso
Formaldehyde emissions kubva kuEWPAA certified products iri pasi pezviganho zvinotenderwa zvekuratidzwa zvakatsanangurwa neWorkplace Australia uye hazviunze njodzi yehutano.
Iwo makirasi e formaldehyde emission muAustralia / New Zealand Standards ane ruzivo mune iri pazasi tafura. Zvigadzirwa zvakanyorwa nemakirasi ekuburitsa E0 uye E1 zvine yakaderera zvakanyanya formaldehyde emissions.
