Description:

CLEAN 105 is a heavy duty non-etch silicated alkali cleaner designed to clean steel, zinc and aluminium and its alloys by spray prior to pre-treatment processes.

Components:
CLEAN 105

Testing Requirements:
Screened methyl orange indicator
0.1M Sulphuric Acid

Health & Safety:
This product is alkaline. Refer to the Health & Safety data sheet for safe handling and use.

Equipment:
The tank may be of mild steel construction but it is recommended that the fittings are made from stainless steel grade 316S16. This includes the heating elements and any spray nozzles. See a list of suitable equipment here.

Set-up and Testing:
The makeup of the bath should be 15 litres (19kg) of CLEAN 105 to every 1000 litres of water. To prepare a new bath, charge the tank to three quarters capacity with clean cold water, heat to 50°C and add enough of the CLEAN 105 to satisfy the full capacity. Mix well and finally top up the tank with clean water and mix well.

The strength of the solution may be varied depending on the amount and type of soil to be removed. Concentration may vary from as low as 10 litres (12 kg) up to 50 litres (60 kg) per 1000 litres of working solution.

Take a 10 ml sample of diluted CLEAN 105 from the tank, add about 5 drops of screened methyl orange indicator and titrate with 0.1N sulphuric acid until the green colour changes to red. Note the volume of 0.1N sulphuric acid in ml required. This is referred to as the pointage.

The strength of the ready for use CLEAN 105 solution is determined in accordance with the following table:

Pointage Litres (kg) AQUUS Clean 105 liquid
4 10 litres (12kg)
6 15 litres (19 kg) - RECOMMENDED STRENGTH
8 20 litres (24 kg)
12 30 litres (36 kg)
20 50 litres (60 kg)

An addition of 2.5 litres (3 kg) of CLEAN 105 per 1000 litres of working solution is required to raise the pointage by one.

Automatic equipment can be used to control the solution. It will however still be necessary a manual pointage check at regular intervals.

Process:
The work is sprayed with CLEAN 105 for sufficient time to allow cleaning to be completed, usually between 20 seconds and 3 minutes.
The operating temperature is usually in the range 45 - 60°C.

The cleaning solution gradually accumulates greases and soils and it should be discarded when the contamination interferes with cleaning efficiency.

Water Rinsing:
Following the CLEAN 105 stage the work is rinsed with one or two stages of water rinses which are overflowed sufficiently to prevent excessive contamination. Testing and control of rinse stages are covered in Technical Bulletin Number 1.

Effluent:
CLEAN 105 solution must not be discharged to main drainage without neutralisation and removal of any separated oils and solids.
