1Circle sinnner in cleaning. How is defined the circle sinner. 4 axes circle Sinner. Action items in the circle Sinner


In cleaning operations, the final result is influenced by four inter-dependent factors, grouped in the Circle of Sinner.

If one factor is decreased, it must compensate for this loss by increasing one or more of the other factors.

Factor 1: Chemical Action


Represents the action of an acid or alkaline detergent solution. This action is increased or decreased by the concentration of pure product contained in the solution (water + product).

It is important to respect the dilution of product in cleaning operations. The "on - dosage" and "sub - metering" bring impact on the expected result.


2nd Factor: Action Mechanics


It is the action brought by the use of materials (single brush, scrubber) which generates a frotement and pressure.

A hardware fault, the agent is considered mechanical action by action of rubbing it with a scraper or stricker. In the operations of cleaning, the mechanical action is to be modulated to avoid alterations of the support.


3rd factor: Action Temperature


The thermal action illsutre in several cases in cleaning activities

The water temperature in the dilution of product: Hot water promotes detergency of a product, and the different powers (wetting, sequestering).

This notion is reflected in the case of dishwashers and washing machines where the impact of temperature has a direct influence on the result.

The thermal action is provided by the friction of a disk on a support (spray method, dry etching). It promotes the action of thermo-reactive products such as products for the spray method and dry cleaners.


4th factor: Time for Action


During cleaning operations, the action time is combined with the chemical action.

It is the fact of leaving the product to act on the support, which increases its cleaning power.

Example: On a wet etching, the action of leave for the stripping solution can loosen, dissolve and soften the layers émulion.
