Optimisation of the Cleaning Service of Floor Cleaning Enterprises with Regard to Life Time of Floorings – Identification and Optimisation of the Wear Properties of Film Layers and Resilient Floorings
AiF 12346 N
The loss of the optical impression of floorings and the reduction in the life time as a result of surface destruction only by walking on the surfaces is called wear. For reduction of the wear and increasing the life-time of film layers and resilient floorings, there are improvements in the cleaning and maintenance necessary.
The wear-resistance of floor coverings depends on the abrasion characteristics of the surfaces. This surface properties are based on the surface hardness of the floorings and the coatings.
Since now, only impractical methods to check the wearing quality, like Taber-Abraser- and Stuttgart-Tests are known. Both tests are European standards (EN 660-1 and 660-2), which characterise the wear by measuring the loss of weight and thickness of the floorings by scrubbing with an abrasive test-material on the surface. Correlation between these laboratory methods and the wear as a result of real use cannot be made. Practice relating experiments, in which the wear depends on the human gait and real soil, are too time consuming and not reproducible.
There is a need for a practical method to study the impact of the surface properties on the wear which simulates the human movement with a step-simulator. This includes the reproducible application of a defined species, quantity and size of dirt. Other important parameters are the moisture and the frequency of use. Influencing factors which depend on the floorings are the elasticity, the coatings and the application methods.
To assess the quantity of the effect of the parameters, there will be various objective physical measurements, like the loss of weight and thickness, surface roughness, colour, brightness and reflection, adapted. Based on these data there is an optimisation of the wear resistance of floorings possible. The main topic is an attractive look of the floorings whilst using.
