Barrier system is designed so that enough little in the interval of adjacent support strip, supporting member or supporting area, and under the power that prevents to run into usually in use, the object or the material that are placed on above it contact basically with absorbed layer.Barrier system also is preferably under this common power basically can resistance to deformation, thereby keeps separating between object or the absorbed layer of material below it.The material that is used to form barrier system can increase its elasticity, makes the distortion can run into some slight extent in use, but distortion is temporary transient character, when external force when object or material are removed, barrier system can return to its undeformable basically state.
If be subjected to by sharp objects or parting tool, as have elongated and the bump of the cutter on wire limit basically, then the orientation of Fig. 1 sheeting 10 preferably makes barrier rib 40 be positioned to be substantially perpendicular to the direction on bump limit.This orientation help to guarantee the bump limit at least with one, preferably contact and distribute impact with several barrier ribs, and guarantee the bump limit not with compare mutually more fragile absorbed layer with and following isolation layer contact.
Barrier system is preferably made by durable in use, flexible, anti-cutting and/or anti scuffing/lost material.Can utilize known common materials with this character in the present technology, comprise such material: they have height toughness, the interlocking molecular structure of higher molecular weight material and higher coefficient of sliding resistance usually.Suitable material comprises polymeric material, as EVA, high density polyethylene (HDPE) (HDPE), low density polyethylene (LDPE) (LDPE), linear low density polyethylene (LLDPE), polyvinylchloride (PVC), plastisol, polypropylene (PP) and polyurethane, encryption paper wood etc.
Fig. 2 has described another embodiment of sheeting 10 of the present invention.In the embodiment of Fig. 2, form a barrier system with a continuous barrier rib that stops grid 50 alternate figures 1 embodiment.Stop that grid 50 can integral body make, perhaps overlapping the and crossing pattern by each discrete bar forms, and discrete bar is interconnected to continuous structure.
In Fig. 2 embodiment, barrier system is similar in appearance to the system of Fig. 1, but provides omnidirectional protection to the bump limit as cutter or sharp objects.Therefore, can place the sheeting 10 of Fig. 2 on any desired direction, still can provide protection for absorbed layer and isolation layer the direct contact on this bump limit with respect to the bump limit.
Another embodiment of sheeting 10 of the present invention as shown in Figure 3.In this embodiment, many discrete absorber elements 60 have substituted the continuous absorbed layer 20 of Fig. 1 and 2 embodiment.Absorber element 60 comprises the discrete deposit of absorbing material, as is suitable for forming the material of continuous absorbed layer, and is connected with space in stopping grid 50 continuously.Therefore, the surface that is formed by adjacent absorber element surface is periodically disconnected by the barrier system that extends in its outside.As shown in Figure 3, barrier system directly contacts with isolation layer, makes the power that acts on the barrier system outside face walk around absorbed layer and pass to isolation layer.So having reduced, this configuration force liquid to flow to possibility on object correlation or the material from absorbed layer.
As the absorbing material layout of the compartmentization of Fig. 3 trend towards liquid be limited in the original liquid deposition near because impervious bottom and do not absorb, impervious grid that stops continuously prevented the migration of liquid between adjacent absorber element effectively.Though the absorbing material to some purposes compartmentization distributes and may wish, for most of purposes, preferably utilizes continuous absorbed layer at present, so that maximum absorption power to be provided.
Fig. 4 has described another embodiment of sheeting 10 of the present invention, and it is general similar to Fig. 3, but wherein continuous stop grid 50 and isolation layer 30 make integral body, preferably are integral.Owing to reduced the number of independent component, these elements particularly can move under influence of shear force under the external force influence mutually, therefore thisly be configured as final total additional integraty and stability is provided.As Fig. 3, Fig. 4 embodiment has also guaranteed to act on power on the barrier system outside face and can walk around absorbed layer and pass on the isolation layer.
In the general Fig. 5 embodiment similar to Fig. 2, barrier system comprises a continuous grid 50 that stops.But the sheeting 10 of Fig. 5 comprises a continuous grid 50 that stops, it comprises thinner layer or the structure that is superimposed upon on the respective shapes supporting member 70.Supporting member 70 can by with stop grid 50 identical materials, make with absorbed layer 20 identical materials or the material different with these two adjacent elements.Configuration as shown in Figure 5 allows that it proves more cheap to stopping that grid adopts thin material, and still can provide the desirable degree that stops for being placed between object on the sheeting or material and the absorbed layer by supporting member 70.
Fig. 6 has described another presently preferred embodiment of sheeting 10 of the present invention.Fig. 6 embodiment is general similar to Fig. 5 embodiment, but difference is: be used for the thin supporting member of grid 50 and the absorbed layer 20 of stopping and make integral body and one, and taked the shape of the profile region 25 of absorbed layer 20.Profile region 25 has an aspect in the sheeting plane, and it is basically similar in appearance to the shape that stops grid 50.Though can utilize diversified forming technology process to make the profile region of absorbed layer, at present preferred technological process is to utilize the profile shaped structure to make the absorbed layer of fibrous a, cellulose base, for example at the following technological process of announcing in the US Patent of transferring the possession of of entrusting together, introduce here as a reference: 4,514,345 of Johnson etc., 5,098,522 of Smurkoski etc., 4 of Trokhan, 528,239, and Trokhan 5,245,025.
