CONSTRUCTION
OF A “CHEMICAL RACK”
ABSTRACT
The project done was a metal
chemical rack. The rack was made of steel, which is soft to cutting, blending
and several other operations applied to the metal during construction.
The main purpose of constructing this
metal rack is to be used for storing chemicals in the laboratory for easy
accessibility and safe keeping.
The to tal cost of the
constructional project was estimated at the sum of Ten thousand (#10,000.00).
This includes fabrication, welding and painting cost. The chemical rack is
relatively cheap and it is light in weight.

INTRODUCTION
A rack is used / set
for holding or storing chemicals in the laboratory. They are of different
types, such as plate rack ,toast rack and wine rack .but the one we shall focus
our attention on will be that of “chemical rack “,which is used for storing
chemicals in the laboratory or used in a chemical process .In the industries or
laboratories .materials are stored in the chemical rack refer to as
chemical storage or facility for storage.
The material
selection for the construction of any rack strongly depends on the properties
and purposes that the rack will serve. Generally, considering all the metals
and non-metals have their individual merits. But point to comparison
between them will definitely show that in general, metals have a lot of
advantages over non-metals.
For example, while
many type of metal are suitable for high temperature operation, non-metals such
as wood and glass are suitable for lower and limited range of
temperatures. Metals posses a wider range of chemical stability than
non-metals.
So, it can be said
that the obvious advantage of first cost cheapness of non-metalic materials is
counseled by other disadvantages of non-metals, the most glaring of which is
that of narrow applicability.
When considering the
cost also, the first cost of materials is even not taken as sufficient
indicator on which to based the selection of construction materials. The
following cost factors among others must be considered. Fabrication cost,
installation cost, maintenance cost and cost of replacement. These cost
must be considered in the material selection for construction.
Rack derive its name
and purpose sometimes from the material of construction and also the shape it
takes. Since rack built in homes are of woods or plastics usually used
for storing drives and plates in the Kotchen. Most racks used for
domestic purposes such as keeping of dishes and provisions, are usually of wood
and in this case there is no observation of all the operation involved in the
construction of metal rack. This is because of the soft nature in the
cuing off of excess of wood during construction. Instead the used of
welding, nail is used in the arrangement of different parts of the rack.
Another major difference that is better than those rack made of wood and those
made of metal is that, wooden rack cannot protect the inside in the presence of
fire outbreak without getting burnt. But the metal rack can protect the
things inside it in the presence of fire. Also wooden rack can easily
rust or decay as a result of chemical split on its surface.
There are several
types of metals that can be used for construction. Metals for
construction include: Gold, Silver, Bronze, and Aluminum, Iron and Steel.
There are usually about three types of steel as it constitutes the widest uses
of metals. These types include low carbon steel that has about 0.3%
carbon, medium carbon steel that contain about 0.3% - 0.7% carbon, and high
carbon steel that contain 0.7% - 1.7% carbon.
Steel are used in the
construction of metal rack, because it is soft to cutting, bending and several
operation are applied to the metal during construction. The galvanized
type of steel has a nature of stainless steel and so it does not support
rusting. Because of this, it is not painted after using it for
construction. In the fabrication of sheets of metals, several types of
gauge 20, 18, 16, 20, gauge 18, gauge 16, gauge 14, gauge 12 and gauge 10,
“gauge 22” has the least thickness while ‘gauge 16” are the best types for
construction of metal racks.
