Industrial flooring testing

When formulating a system for optimum abrasion resistance, both the epoxy/resin hardener binder system and the filler blends used appear to have an influence. The simulation of abrasive service loads on industrial floor toppings in a laboratory is not simple, and numerous wear test machines have been devised. Correlation between different wear test machines is not always good, although most...

Standards for finished industrial floors and their execution do not currently exist, and nor do standards for testing of the properties of the flooring materials. The current approach to the design and construction of industrial pavements in many cases is based on wide, mostly negative experiences over time. 

Nowadays, with development of industrial and storage technology, industrial floors have to fulfill many special requirements for intended use, which are discussed in [39-41], For this reason, regulations are necessary for proper design, construction, and control of industrial floors and related testing methods.

Acid-resisting Brick or Tile. A fired clay brick or tile of low porosity and high resistance to a variety of chemicals. B.S. 1902 Pt 3.12 specifies an acid resistance test for refractories, Pt 3.15 a test for bulk material. ASTM C-279 specifies three grades according to resistance to H2SO4. ASTM C-410 specifies industrial floor bricks. 

The polymer mortars with SF were tested by Ohama et al. (1989) in view of their application for industrial floors, decorative coatings and repair of concrete structures. The results were interesting and have shown different influence of SF, that is, an increase of compressive strength and resistance to water permeation and penetration of chloride ions, but no improvements have been observed of resistance to water absorption, carbonation and drying shrinkage. Also, adhesion of the composite to covered concrete surfaces was not increased. 

Over the twentieth century, the mbber industry has developed special rheometers, essentially factory floor instmments either for checking process regularity or for quality control purposes, for instance, the well-known Mooney rheometer (1931), the oscillating disk rheometer (1962), and the rotorless rheometer (1976). All those instmments basically perform simple drag flow measurements but they share a common feature During the test, the sample is maintained in a closed cavity, under pressure, a practice intuitively considered essential for avoiding any wall slip effects. Indeed it has... 

Although today s manufacturers of NIR instruments do provide instruments that are surprisingly consistent and precise from one device to the next, the industrial method development chemist is likely to encounter problems when transferring methods from the laboratory to the production floor on a large scale. The instrumental differences that lead to such problems may or may not be of adequate significance to be identified during the instrument qualification tests. Appropriate use of reference standards for performance qualification can certainly reduce the occurrence of such problems. However, in certain cases, one of the many calibration transfer algorithms that have been discussed in the literature over the last decade may be required for successful transfer and implementation of a calibration. 

In many applications of low molecular weight hydrocarbon resins, including flooring, adhesives, rubber compounds, inks, and coatings, the best performance is often associated with plasticizers that are marginal solvents rather than perfect ones. The difference between the resin parameter and the plasticizer parameter indicates the place of the system in the Flory-Huggins phase diagram. The separation of phases is responsible for the improved physical properties. While the difference of the parameters readily explains the behavior, the parameters for many industrial materials are not sufficiently well defined, and specific solubility tests must be used to control both resin and plasticizer. 

In the same 25-ft tunnel test the so-called smoke development index (SDI) can also be determined. The smoke measurement is based on the percentage of retardation of light passing through the tunnel exhaust stream and detected by a photocell, and then data obtained are converted to the SDI, with red oak flooring set at 100. AC 174 does not specify any particular SDI as the code requirement, but the industry generally considers SDI above 450 as hazardous and not acceptable, particularly for interior flnish. 

Figure 24.8 shows the layout for testing radiant tube performance in a pilot-scale industrial furnace (PSIF) of the Canmet Energy Technology Centre, Ottawa, Ontario, Canada [9]. The furnace is 4.5 m x 3.0 m x 1.0 m (inside dimensions) and it can be modified to simulate any industrial furnace geometry. With a firing rate of 1.2 MW, the temperature, heat transfer, and chemical environment found in most industrial processes can be emulated as well. The furnace is equipped with a calorimeter for total heat flux (34 cooled plates on the floor of furnace). 

Energy absorbent methods have been widely used by the footwear and flooring industries, for example the apparatus described by Wilson and Mahoney [21). Energy acquired by a trolley running down an incline is absorbed by the braking action of a heel on the horizontal test surface at the base of the incline. A similar test appears in BS 7044 [22] for artificial sports surfaces. 

I am an Industrial Hygienist and received a caU this morning to test for mold. The customer is a Periodontal Doctor with ten employees. The building is two floors with a crawl space below them. The professional office building itself is visibly clean, including signs of water intrusion and visible mold. The Crawl space is dry, the wood is clean with some suspect insulation, which I took a bulk sample of. I collected several Air-O-Cell samples and expect to have data within 48 hours. I have advised my client that these are not symptoms that have been associated with mold contamination.
