| CHEMICAL PRESSURE TREATMENT |
 |
The air seasoned timber
is placed inside the Chemical pressure Treatment Chamber.
The vaccum is created and maintained as per 18:401-1982.
The preservative used (CCA-ASCU Make)is injected in the
wood under pressure as per IS specifiction. Chemical Treatment
is needed in order to increase the life of Timber to withstand
all types of insects, fungus, termites and other wood borers,
rot etc. The life thus of such timber is much increased
due to preservative treatment |
After the vaccum is
created to remove superficial moisture in outer cells of
timber and on releasing the vaccum, the residual chemical
is transferred to reservoir and the timber is taken out
from treatment plant. |
| KILN SEASONING |
It is done with steam
operated system which is very essential to prevent dimension
changes such as expansion, shrinkage etc. which result in
warping, cracking etc. Kiln sasoning completely sterilises
the timbers and as such timbers are resistant to insects,
fungus attack etc. |
The timber is stacked
properly as per procedures taWdown in IS 1141-1973. The
kiln seasoning in whcih temparature and humidity is controlled
as per guidelines laid down in IS -.1141-1973. In kiln,
the moisture of wood is reduced very slowly under the controlled
conditions to avoid and deterioration of quality of wood.
This process takes approximately 10 to 15 days time, depending
upon area and cliamtic conditions. |
| JOINERY WORK |
|
The kiln
seasoned and Chemically Pressure Treated wood is used to
manufacture shutters, frames wooden furnitures and other
desired products, the wood is passed out through various
stages of wood working machines and finally assembled to
form shutters or frames as per the design, drawings, specifications
of the purchaser by keeping in view of the specifications
of IS:l003(Pt.ll)83. |
| FINISHING |
|
Final product
after thorough inspection and test have the finished of
smoothness with well-planed faces. It is flat and well-sanded
to a smooth and level surface. Defective knots on surfaces
if viewed are completely bored or cut and tightly plugged. |
Before delivery,
one coat of primer is applied as per IS: 1003' Pt.1 -77
at our Factory to protect the doors, shutter, frames etc
against weather effects.During all the above process, the
involvement of quality control is very important aspect
and which is carried out as tolS:Code(s). |
