Comparison
of merit and demerit. |
Traditional
backing material for S.A.W. is flux
composed of phenol resign an arganic
compound, thermally set at 180~200℃
①it burns with the high temperature
caused by welding and discharges plenty
of noxious gas, ②therefore a great deal
of dust is generated when solid flux
is removed after welding.
|
Since the product
C.B.M is composed of ceramic powder,
an inorganic material, shaped with pressure
and heat-treated at high temperatures
of 1350℃ : ① it is very safe against
the high temperatures caused by welding
and discharges no noxious gas, ② and
no dust is generated after welding as
the ceramic form is maintained intact.
|
Since magnetic clamp is
required for installation work space
is limited,
installation is difficult and the time for installation is very long.
|
Since installation is
carried out with aluminum tape easy
work is possible in a narrow space,
the time for installation is reduced
and installation work is simple.
Magnetic clamp is completely eliminated.
|
Deteriorates working environment.
Use of asbestos :
Causes cancer Burning
of solid flux during welding :
Noxious
gas is generated.
Burning of corrugated
cardboard etc :
Strong fume is generated.
|
Creates very pleasant
working environment.
(Abbestos, solid
flux, corrugated cardboard etc, are
completely excluded)
|
Because of difficult installation
work reduction of productivity and increase in production cost are caused.
|
Because of easy installation work enhancement of productivity and cost reduction may be realized.
