| GENERAL The glass is firstly
toughened by a regular physical tempering furnace
which is provided by the buyer. Then the tempered
glass is processed by the fireproof glass production
equipment described here and below.
TECHNICAL FEATURE
1. The equipment consists of two pre-heating
chambers, one chemical ion exchange tank, two
glass racks and one platform on top floor.
2. The pre-heating chamber is made of steel
plate with ceramic fiber insulation. Each chamber
has one blower on the top for hot air circulation.
The temperature is controlled by automatic program.
The top and bottom covers of the chamber can
be opened and closed controlled automatically
for the access of glass rack. A hydraulic system
is equipped to lift up and lower down the glass
rack. These two pre-heating chamber locates
on the top floor of the equipment and are able
to move right or left on rail. There is a staircase
which access to the platform on the top floor.
3. The chemical ion exchange tank is made of
#304 stainless steel box insulated by ceramic
fiber. Temperature is controlled by program
automatically. During the start up, the potassium
salt takes about 24 hours to fully melted.
4. The #304 stainless steel glass rack is used
for glass loading. The two racks can be lifted
up and lowered down.
PRODUCTION PROCEDURE
Chemical strengthen
1. One of the glass rack is on floor. Glass
is loaded onto the rack which is then lifted
up by means of hydraulic system to one of the
pre-heating chamber through the access of the
bottom cover. After the bottom cover is closed,
the glass is then pre-heated. When it is ready,
this pre-heating chamber is moved, with glass
rack inside, right above the chemical ion exchange
tank through rail. Then, the bottom cover is
opened and the glass rack is lowered down into
the chemical ion exchange tank by hydraulic
system. Then the chemical ion exchanging is
started.
2. Meanwhile, glass is loaded in another rack.
The glass rack is lifted up to another pre-heating
chamber through the access of the bottom cover.
Then the bottom cover is closed.
3. After the chemical ion exchanging is completed,
the first glass rack is lifted up to the first
pre-heating chamber which is moved sideward
and then lower down onto floor ready for glass
unloading.
4. Meanwhile, the pre-heating of the glass
inside second glass rack is completed. It is
then lowered down into the chemical ion exchange
tank for ion exchanging.
5. The cycle is repeated. The chemical strengthen
glass is fireproof glass.
INSULATING
If top level of fireproof is required, the
chemical strengthen glass is required to fabricate
into insulated glass. It could be double glass
or triple glass or multi-layers depending on
how long the glass is required to resist the
fire. Some instrument and tooling are required
to fill up the spaces between two pieces of
glass with special chemical. |
