What Do You Already Know?
Let us determine how much you already know about checking conditions of tools and equipment. Take this test.
What Do You Need To Know?
Read the Information Sheet 2.1 very well then find out how much you can remember and how much you learned by doing Self-check 2.1.
Information Sheet 2.1
A lubricant is a substance introduced to lessen friction between moving surfaces. It may also transport external particles. The property of reducing friction is known as lubricity.
Types and Uses of lubricants
1.Anti-rust lubricant spray:
o loosen rusted part
o cleans and protect
o drives out moisture
o stops squeaks
o free sticky mechanisms
2.Wire Pulling Lubricant:
o does not damage insulation
o cling to wire and dries to a slippery film
o suitable for use with wire or cable covered with rubber (t, thw, thhn, etc)
3.All Purpose Anti Rust Lubricant:
o anti-rust
o lubricating
o rust removal
o decontamination
o conductance
4.Lubricant Oil and Engine Oil:
o lubricating the gear
o cleans and protect
o drives out moisture
5.Silicon Lubricant:
o heat stable
o lubricates
o protects
o reduces friction
o water repellent
Reminders
A good lubricant possesses the following characteristics:
High boiling point.
Low freezing point.
High viscosity index.
Thermal stability.
Corrosion prevention.
High resistance to oxidation.
Types and Kinds of Cleaning Solvents
Solvent is a component of a solution that dissolves solute and is usually present in large proportion or amount. It can be classified as polar and nonpolar. Polar solvents are solvents which dissolve/are soluble in water; while nonpolar solvents are solvents which do not dissolve/are insoluble in water.
Solvents are usually used for cleaning in workshops. They are water, gasoline, kerosene, thinner and detergent soap.
The table below shows the kinds of cleaning solvent based on their solubility in water.
Uses of Cleaning Solvents
5’s Approach in workshop keeping
5’S is a reference to a list of five Japanese words translated into English. This is an approached of organizing and managing the workplace and work flow with the intent to improve efficiency by eliminating wastes, improving flow of production, reducing process delays.
These words are:
