INTERIOR BUILDING MATERIAL MADE FROM PAPER-MILL
SLUDGE AND METHOD FOR MANUFACTURING THE SAME
Technical Field
The present invention relates to an art for
manufacturing interior decorating material for building by
using paper-mill sludge produced as waste matter during a
paper making process in a paper mill and particularly to an
interior building material made from paper-mill sludge and a
method for manufacturing the same, which allow the provision
of the products excellent in quality and strength when they
are implemented as interior decorating material for building.
Background of the Invention .
Generally, it is true that in the recent years our
environment suffers extraordinarily from pollutants with the
industrial development.
The paper-mill sludges among them pose a serious
problem of contaminating the soil and water besides the
difficulty in its treatment due to its inclusion of various heavy metals in the course of paper-making processes.
Such a conventional paper-mill sludges have been put
to use only limitedly, for example, for fresh egg receiving
plates in a poultry industry, but moreover in a unwelcome
situation on the sanitary ground.
Therefore, most quantity of the produced sludge is
dumped, wherein incinerating method is usually employed,
with the drawback of high treating cost for the necessary
drying before incinerating as well as the danger of air
pollution due to the harmful gases produced during the
burning, while the burying method is hardly thinkable because
of extraordinary treating cost plus the worry of contaminating
the water system and soils.
Generally these paper-mill sludges comprise a large
proportion of residual pulp and various hazardous chemicals
such as Cd, Hg, Pb, H2O2 or the like.
Conventionally the sludge was discharged with the
water content of approximately 65%, with some deviations
depending on the paper mills, but recently the water content
was reduced down to more or less than approximately 40% on the ground of post-treating cost.
As an other significant matter, these paper-mill sludges
contain a part of some powder, a condition on which this
material may be developed to gypsum board substitute to be
used as imitated plywood.
Summary of the Invention
Thus, the present invention which was created to
resolve the above-described conventional drawbacks has its
object in disposing a waste in an advantageous and economic
way and simultaneously to provide a new product by
producing an interior building material through recycling the
paper-mill sludge.
To that end, the product according to the invention
comprises, by weight, 35 - 39 parts of paper-mill sludge, 10 -
15 parts of diatomite, 10 - 15 parts of gypsum, 8 - 10 parts of
asbestos, 4- 8 parts of calcium carbonate, 9 - 15 parts of
clay, 3 -8 parts of calcium hydroxide, and 3 - 1 1 parts of
silicate.
In the above , the calcium carbonate may be substituted by 8 - 12 parts by weight of agalmatolite.
The method for manufacturing the product according to
the present invention, which is composed as described above,
is explained below.
The composition comprising the respective materials,
formulated as above, is transferred by way of a screw
conveyor to a kneader, wherein sufficient blending is
conducted and 26 parts by weight of ethyl silicate, a curing
agent in the form of liquid, is introduced before further
blending. After completion of blending, 9 parts by weight of
isooctyl alcohol as a defoaming agent is added, 35 parts by
weight of industrial water is also added and the resultant
mixture is kneaded immediately before it is transferred to a
metal mold via a screw conveyor.
The kneaded mixture is poured in the mold which is so
configured as to manufacture the product of a definite size
and which has been heated to a temperature of 850°C . At the
metal mold, molding is performed under pressure with a
weight of 550 tons, then flame retardant coating is conducted
by using ammonium dihydrogen phosphate for necessary surface treatment, bonding material is spread over the
surfaces of the raw product through air spraying, paper is
adhered on opposite surfaces of the product for exterior
decoration and finally rapid drying is conducted for about 40
seconds by using a gas heated to about 180°C , to thereby
provide the finished product.
Detailed Description of the Invention
A preferred embodiment of the present invention is
explained as follows.
As described in the foregoing, the product according to
the invention comprises, by weight, 35 — 39 parts of
paper-mill sludge, 10 — 15 parts of diatomite, 10 - 15 parts of
gypsum, 8 - 10 parts of asbestos, 4-8 parts of calcium
carbonate, 9 - 15 parts of clay, 3 -8 parts of calcium
hydroxide, and 3 - 1 1 parts of silicate.
In the above, the calcium carbonate may be substituted
by 8- 12 parts by weight of agalmatolite.
When the content of the sludge is less than 35 parts
by weight, tensile strength is reduced, while both noninflammability and endurance are reduced when 39 parts
by weight is exceeded.
Similarly other components should also be kept below
the upper limit to preserve appropriate tensile strength and
particularly workability and endurance are severely lowered if
calcium carbonate is contained at more than 8 parts by
weight.
Furthermore, the substitution of agalmatolite for the
limestone component would have the effect of enhancing both
the sintering property and the endurance and also a special
advantage because it is known to emit far infrared ray,
supposedly beneficial to health, except for some burden for
a little higher price.
The building product according to the present
invention, which is composed as described above, can be
prepared in accordance with the following steps of process.
The composition formulated as mentioned above is first
transferred to a kneader through a screw conveyor, in which
kneader following complete blending , 26 parts by weight of
ethyl silicate as a liquid type curing agent is added and blended. After complete blending, 9 parts by weight of
isooctyl alcohol as a defoamer is added, and subsequently 35
parts of industrial water is added and rapid kneading is
conducted before the mixture is moved to the metal mold
through screw conveying.
The kneaded mixture as the result of the
above-described step is poured into the metal mold which is
so configured as to manufacture the product of a definite size
and which has been heated to a temperature of 850°C . At the
metal mold, molding is performed under pressure with a
weight of 550 tons, then flame retardant coating is conducted
by using ammonium dihydrogen phosphate for necessary
surface treatment, bonding material is spread over the
surfaces of the raw product through air spraying, paper is
adhered on opposite surfaces of the raw product for exterior
decoration and finally rapid drying is conducted for about 40
seconds by using a gas heated to about 180°C , whereby the
finished product is obtained.
The reduced weight of the building boards according to
the present invention is clarified from the following table of comparison with the conventional ones according to product
specification.
Table
Figure imgf000010_0001
As can be seen from the above table, light weightiness
of products can be realized according to the present
invention, as the weight of the inventive boards is markedly
reduced in relation to the conventional boards.
Moreover, various measurements for physical properties
attested the superiority of the inventive products over the
conventional ones, wherein the tensile strength was 151 .0 psi
for the invention versus 54.9 psi for the conventional art, for
09T specimen, and such important variables as flahing point,
ignition point and melting point also showed the excellence for the invention and specially for soundproofing effect, the
inventive product exhibited the decrease of decibel level over
the conventional one by 8% in the case of 12T thickness and
17% in the case of 9T thickness.
Therefore, the building boards according to the present
invention have the advantages of the reduced cost for raw
material due to the recycled use of paper-mill sludge, the
improved workability and handling due to the reduced weight
and firmness and the increased possibility of providing
diversified products due to the use of metal molds for
manufacture and in addition to them, the excellent
soundabsorbing effect.
Conclusively, the inventive product having the
above-mentioned composition and functions can be prepared
very economically by using the paper-mill sludge which
caused environmental pollution and disposal cost and so was
classified as a waste, and can be used as an excellent
interior decorating product for constructing purpose, which
product provides simplicity in workability and exhibits high
resistance to heat, humidity, fire and sound.
