fiber at a specific ratio to be bound by a process normally used
for the non-woven fabric, and finally hot pressed into sheet, or
the mixture is treated as a pulp to be dried for serving as a fire
component; accordingly, the process of the present invention gives
accurate control of the mixing ratio of the expansion graphite
powder and allows to increase the containment of the expansion
graphite powder in the fire component up to eighty-five percent

Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention is related to a manufacturing process
for a fire component gives accurate control of the mixing ratio of
the expansion graphite powder and allows to increase the
containment of the expansion graphite powder in the fire component
up to eighty-five percent (85%), thus to significant upgrade the
performance of the fire component.
[0003] (b) Description of the Prior Art:
[0004] Expansion graphite power is used as a component in one of
the contemporary fire constructional materials. Referring to FIG. 1
of the accompanying drawings, the expansion graphite power
(30.about.40%) and the ceramic fiberboard (50%+) are alternatively
laminated, then dry molded in a structure wherein the expansion
graphite power (1) sandwiched by the ceramic fiberboard (2) as
illustrated in FIG. 2. Given with the lamination structure, the
expansion graphite power (1) when subject to heat in case of a fire
will expand for the entire component to fast expand, so to stop the
fire from extending and interrupt further diffusion of the
smoke.
[0005] However, in the prior art, the expansion graphite powder and
the ceramic fiberboard are alternatively laminated, then dry
molded; the expansion graphite powder is integrated only with the
ceramic fiberboard, instead of the ceramic fiber. Therefore, higher
ratio of ceramic fiberboard is required in the component to support
the expansion graphite powder that prevents precise control of the
ratio of the expansion graphite powder, and further fails
increasing the containment of the expansion graphite powder in the
component to upgrade its overall fire resisting performance.
SUMMARY OF THE INVENTION
[0006] The primary purpose of the present invention is to provide a
process for the manufacturing of a fire component. Wherein,
expansion graphite powder, chemical fiber and paper fiber are mixed
at a certain ratio, then bound by means of binding process used for
the non-woven fabric, then hot pressed into sheet fire component.
The process disclosed in the present invention allows accurate
control of the mixing ratio of the expansion graphite powder and
permits the expansion graphite powder to be integrated with
chemical fiber and paper fiber to raise the containment of the
expansion graphite powder in the component up to 85% to
significantly upgrade its fire performance. Alternatively, the
mixture of expansion graphite powder, chemical fiber and paper
fiber is treated as a pulp to be dried and molded into a fire
component.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a flow chart showing 7a process for manufacturing
a fire component of the prior art.
[0008] FIG. 2 is a sectional view showing a structure of the fire
component of the prior art.
[0009] FIG. 3 is a flow chart showing a process for manufacturing a
fire component of the present invention.
[0010] FIG. 4 is a flow chart showing another process for
manufacturing the fire component of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] Referring to FIG. 3 for a process of the present invention
to manufacture a fire component, a mixture containing 50.about.85%
expansion graphite powder and 10.about.50% of chemical fiber and
paper fiber is bound by means of that used for the non-woven
fabric, the hot pressed at 90.about.170.degree. C. for 10.about.180
sec. (with the optimal results achieved at 140.degree. C. for 15
sec.) into 0.5.about.2 mm thick sheet of fire component. Wherein,
the chemical fiber is related to a chemical compound of polyester,
PVA or Acrylic.
[0012] As illustrated in FIG. 4, the expansion graphite powder
(50.about.85%), chemical fiber and paper fiber (10.about.50%) are
fully mixed in water into pulp, then dried at 150.about.200.degree.
C. for 20.about.200 sec. (with the optimal results achieved at
180.degree. C. for 30 sec.) and finally molded into 0.1.about.0.7
mm sheet of fire component.
[0013] Whereas the expansion graphite powder, the chemical fiber
and the paper fiber are mixed before being molded into a specific
formation in the present invention, it not only allows accurate
control of the ratio of expansion graphite powder in the mixture,
but also permits the expansion graphite powder to be integrated
with both of the chemical fiber and the paper fiber, thus to
increase the containment of the expansion graphite powder in the
fire component up to 85% to significantly upgrade its overall fire
performance.
[0014] The process of the present invention for manufacturing a
fire component permits accurate control of containment of the
expansion graphite powder in the fire component and increases the
containment of the expansion graphite powder in the fire component
up to 85%. This application is duly filed accordingly. However, it
should be noted that the preferred embodiment is given only for
reference purpose and not to limit the present invention. Any
structure, installation and characteristics that are resembling or
similar to the present invention shall be deemed as falling with
the purpose and the scope of claims to be claimed by the present
invention
