What is “Richil lining”? |
|
|
|
|
|
In electro static powder painting, the film thickness of approximately 0.6 mm is formed with
recoated thin films of approximately 50 μm, but in RichilR lining, the
film thickness of 1-3 mm
is attained by several firings.
The secret to this is in our rotating furnace and special slurry coating.
By previously injecting
fluorocarbon resin into the interior of the coated materials (i.e. tanks)
and then firing the coated
materials themselves while three-dimensionally rotating them, the thick
film lining with less heat
application repetition has been realized.
Applicable under negative pressure conditions.
Completely adhesive to the base material metal because of fire lining. No extra designing such as
creating vent holes for coated objects is required. Fully applicable under
full vacuum conditions.
Seamless Film.
The film is formed by firing that completely dissolves fluorocarbon. Therefore
it is
completely seamless.
The interior of the coated object will be entirely covered with one piece of film.
As there is no trouble in resin seam welding, which is often seen in the
sheet lining,
the accumulated residual liquid in the seam can be prevented.
Compatible with complex forms.
In electro static powder painting, a method to spray powder material has its limitation
in coated material forms. Richil lining is applicable to complex forms
that are inapplicable
with glass linings and electro static powder painting.
For example pipes. The maintenance can be simplified, as reducing the number of pipe
pieces lowers the number of flanges.

Construction Method |
|
|
|
|
|
Richil lining is formed in the process of filling the opening of the device,
setting it in
a biaxial rotating furnace and then melting fluorocarbon resin in a three-dimensional
furnace.
The maximum construction size is a size that can be fit into aφ3,200 sphere, and the maximum
construction weight is up to 2 tons.

Multilayer Structure |
|
|
|
|
|
Fluorocarbon resin generates contraction and peel problems when formed
into a thick film.
In particular, for cases that adhesion is required or when used at high temperature where heat
contraction tends to occur, we thus have adopted a structure to weaken
the peel force by composing
the multilayerd film and lowering the contraction rate by placing filling material at the bottom layer
to disperse the contraction force concentrated on the boundary surface
of the base material.
