INTRODUCTION
Industrial production is a process of
using of chemicals and other related substances including water which is a
natural substance to come-up with finished products. These involves the
production of equipments such as iron, rubber etc.
For the purpose of this discussion,
we will be using chemicals and other substances to produce consumables.
Industrial consumables are quite
enormous, but for the purpose of discussion will be limiting ourselves to:
1. Bleach production
2. Soap production
3. Cosmetics production
PRODUCTION OF BLEACH
When such chemicals are combined
together in water, it is allowed for a period not less than 42 hours before it
can be used for washing.
Bleach is a product, produced by the
combination of certain chemicals. USES OF BLEACH
Bleach has so many economic importance’s
among which are;
1.
It’s
used for washing of cloths,
2.
It’s
used washing of toilet bowls
3.
It’s
used for cleaning of chairs and tiles.
4.
Its
also prevent germs
When producing bleach,
the quality control can be determined using clothing material (coloured), this
called fiber testing.
CHEMICALS NEEDED FOR BLEACH PRODUTION
1.
Sodium
Hydroxide: it’s also known as caustic soda. It serves as bleaching agent, stain
remover.
2.
Chlorine:
this is a bleaching agent that fades colour in any production process
3.
Sodium
carbonate/ soda ash: it helps in breaking-down chlorine for its effect to be
felt in the production.
DETERGENT PRODUCTION
Detergent is a surfactant. A
surface active agent. It has the ability to act on surface whereby leaving the
surface clean and neat.
FORMS OF DERTERGENT
Detergent as a surface active agent
exists in two different forms;
(1) Powdered
detergent
(2) Liquid
detergent
USES OF DETERGENT
Detergents are used for various
purposes. These include (1) washing of clothes (2) scrubbing of the floor (3)
washing of hospital equipment (4) washing of factory equipment etc.
Detergent is also used as car wash.
However the best car wash detergent is liquid detergent because it contains
little or no sodium hydroxide which is capable of removing colour from the
surface.
PRODUCTION EQUIPMENT
Production equipments are as
follows:
i.
Mixer:
The mixer is made up of a bowl and stirrer which can be manual or electric
powered. This depends on the financial capability of the producer.
ii.
Drier:
This is used to dry the product. Drier can be electric or manual. Manual drying
entails spreading the product under the sun so it can dry through the heat of
the sun. This however can take some time and it can delay business especially
in rainy seasons.
iii.
Hydrometer:
This is equipment is used to determine the water density in caustic soda.
iv.
Face
Mask: This instrument is for protection of the nose and mouth from
direct inhaling of chemicals
v.
Lab
Coat: This should be made with nylon material because such material
withstands the penetration of chemicals.
vi.
Hand
Gloves: For the protection of hands, this should also be made with nylon
material
vii.
Plastic
Bowl: For storing of water e
viii.
Weighing
Balance: This is for weighing chemicals to ascertain the quantity to be
used at each point in time.
CHEMICALS AND
INGREDIENTS
1. SODIUM HYDROXIDE (CAUSTIC SODA): Sodium Hydroxide otherwise
known as caustic soda, it’s a powerful base. This chemical must be soaked in
water for a period not less than 24hrs before use in production.
This process is simply known as fermentation of caustic
soda. Once the caustic soda is fermenting, the temperature rises up to 1000c
and later falls to between 0o c-300c.when it is at low
degree, it will then allow for accurate measurement of water density in the
chemical, using the Hydrometer.
Note: If caustic soda is hot as you pour water into it, the
temperature has risen and if you measure it at that point in time, the degree
of the water density will fluctuate, and this can negatively affect your entire
production.
2. SODIUM
CHLORIDE: This substance is popularly known as industrial salt. Sodium
chloride helps to control the harshness of the caustic soda. The absence of
caustic sodium chloride in the product can cause peeling of skin after using
the product.
3. SODIUM CARBONATE: This is also known as Soda Ash. Sodium
carbonate is filler, it is there to fill the gaps and make the detergent more
compact. It helps the detergent to come out in grains and also increase the
quantity of the detergent.
4. FATTY
ACID: Fatty acid can be obtained from palm kernel oil (PKO), olive oil,
vegetable oil etc. It is rich in glycerol from where we derive glycerin, which
is very nourishing on the skin.
5. SULPHURNIC
ACID: This is a foam or lather booster. It helps the detergent to foam
well thereby making the product very active. Lather or foam in detergent
suspends dirt and does not allow it to get back to the cloth.
6. SULPHURIC ACID: It helps the detergent to dry faster and
come out in powdered form. It does not allow it to form lumps.
7. AROMATIC AGENT: This is industrial perfume used for
giving the product the desired fragrance.
8. BLEACHING AGENT: Bleaching agent can be obtained from
chlorine or hydrochloric acid. This also helps to make the product more active
in removal of dirt.
9. WATER: This is for fermenting the caustic soda and
dissolving of the ingredients that comes in powdered form.
10. HYDROGEN PEROXIDE: This is for oxidation and is the last
thing to be added during detergent production.
DETERGENT PRODUCTION PROCESS
1. The
first thing is to determine the volume of your production.
2. Carry
out the measurement of the chemicals and ingredients that will give the
quantity of the volume.
3. Ensure
that your caustic soda is well fermented for at least a period of 24hrs.
4. Make
sure that the water density does not go beyond 12.75, 12.80 or 12.90, but note
that when the water density is too low, the product will be too harsh, though
the drying process will be faster.
5. Pour
the fermented sodium hydroxide into a bowl.
6. Pour
in soda Ash together with the industrial salt.
7. Pour
in your fatty acid.
8. Add
sulphurnic acid.
9. Add
colour: Note that if the colour is oil soluble, you mix it with a little fatty
acid before pouring it in.
10. Next
is aromatic agent.
11. Finally
you gradually introduce the hydrogen peroxide.
Note: Each chemical or ingredient you add, you are to stir
well the entire product for at least three minutes before adding another. This
is to allow each chemical to blend to achieve proper reaction.
This whole process of soap of detergent production is known
as saponification.
When you are done, you pour out and spread the product for
drying.
