What does Good, Better, Best refer to?
It refers to our different Adsorbent Solutions. Because the demands of the spill control market are varied and needs and priorities determined by risk factors, Can-Ross offers a range of solutions. In an effort to provide our customers with the knowledge to make the correct choice, we have provided the following generic guide to product selection.
All products offered in this category are price driven. The manufacturing process employed to create SMS (spunbond – melt-blown - spunbond) polypropylene synthetic lends itself to producing an economical alternative in adsorbent offerings. By combining melt-blown coarse fibre (high absorption – high tensile strength) between two spunbond outer layers, a generally acceptable compromise is achieved. The spunbond fibre “skin,” bonded by either heat embossing or by ultrasonic welding, improves upon the deficient durability and linting characteristics of the coarse fibre center layer but impedes the overall adsorption capability in pads, rolls and booms made from this SMS synthetic. This product line is a viable alternative in warehouses and plants where infrequent, minor and low risk spills occur.
With the product offerings in this category, the term “better” applies almost exclusively to the adsorption capabilities of the 100% melt-blown, coarse fibre synthetic. Products manufactured using polypropylene coarse fibres result in a highly adsorbent alternative that often appears to be the best value. Certainly spill control products are widely assessed by their ability to pick up leaking or spilled fluids. These products do, however, have inherent weaknesses that can negatively impact handling, clean-up and disposal. Having low tensile strength they abrade, lint and tear, especially when in a saturated state. Also this synthetic does not retain the adsorbed liquids to the same degree as melt-blown fine fibres (see “Best” category) and these characteristics will impact the spill control process beyond the initial control and pick-up stages. Products in this category are an economical option when larger and more frequent spills are likely to occur. However, consideration should be given to the price versus cost equation by assessing the risks, dependence on quick reaction and final cost of disposal of fluids and spent adsorbents.
Products manufactured by the melt-blown fine fibre process offer the best in adsorption, retention and tensile strength qualities. The fine fibre construction not only creates a strong synthetic but one with small voids where the fluids are entrapped and retained. The voids created in the coarse - fibre process are significantly larger than those in the fine fibre synthetic and less efficient in retaining the adsorbed liquids.
The product offerings in this premium category will adsorb up to ten (10) times their weight in liquids, will retain a high percentage of what they adsorb, will maintain their integrity through multiple uses and “wring-outs” at the spill site, will not shed or lint causing secondary clean up demands and, through these features and advantages, will provide reduced disposal cost benefits.
When the job is critical due to toxic or flammable spills or containment of potentially large volumes of fluids, not having the best adsorbent products on hand may prove to be a less than ideal choice.
