N2 - The aim of the investigation was to clarity some factors
influencing formaldehyde
emission from particle boars used as wall lining and on
the other hand, to confirm
in practice the results of previous laboratory tests and
of the tests discussed in
the paper.
The investigation concerning the treatment of the edges
of particle board shaved
that the edges always have to be preserved with paraffin
wax before the chamber
test in the laboratory. The same result is obtained when
the edges are painted with
reactive paint. When open joint is used in wall lining,
or when the edges are otherwise left open, the edges must
always be painted with a paint recommended for the
surface of the board.
When particle board is used in wall lining, it is not
necessary to paint its back,
or the surface towards the wall. The research results
shaved that painting the face
of the board in the recommended way is sufficient to
prevent formaldehyde emission.
The applied part of the research was carried out in a row
house that was being
built. Ten similar dwellings were used for the
investigation. The test material
consisted of standard particle boards, processed and
special products, as well as of
gypsum board as reference material. All partitions in one
dwelling were always made
of one type of board. The formaldehyde content of the air
in the dwellings was measured during the different phases
of the building process. Reactive paint was used
for priming of standard boards, the prime of all other
board types was latex paint.
Latex paint was used as paint finish in all cases.
The results show that after priming the formaldehyde
content of the air was clearly
lower than 0.15 mg/m3 in all dwellings. Thus particle
boards painted according to
the manufacturers instructions did not cause injurious
formaldehyde contents. In
the later phases of the building process and when the
inhabitants had moved in, the
formaldehyde content rose in all dwellings and in some of
them as high as over the
level of 0.15 mg/m3. This increase was partly due to
other building and furnishing
materials and to the habits of the inhabitants and, above
all, to the very poor
ventilation of the dwellings.
