Describe in detail
Fig. 1 schematically illustrates the knitting wool carpet of a part of artificial turf.This carpet has the very near wire harness in many intervals 11, and this wire harness is made up of thin bar of the flat bending of U-shaped or strand 12, and this strand constitutes the blade of pedaline.This wire harness is fixed on egative film or the end liner spare 14.This egative film by woven cloth or similarly fibrous material constitute, this fibrous material is with the plastics of stable wind resistance rain composition such as polypropylene fibre or nylon fiber for example.This special cloth must be flexible, perhaps can change with its composition.
Schematically illustrate as Fig. 1, this wire harness is embedded in the fiber that forms egative film or passes this fiber.For wire harness and egative film are combined, scribble suitable adhesive linkage 16.This adhesive linkage can form with the adhesive of viscoelastic polyurethane condensation material or other outdoor that is suitable for, and this adhesive still has elasticity or flexibility.
Carpet is placed on the flexible buffering heelpiece 18.This heelpiece is made of quite thick molded panel or pad, and this pad is molded with the open particle polypropylene that has expanded of resilient micropore.The thickness of this pad is in the scope of about 12.7～50.8mm (1/2～2 inch), and its preferred density is about 24.0～48.1kg/m
3(1.5～3 pounds/foot
3) between.The thickness of this pad depends on that the certain effects of requirement can also change at 6.35mm (1/4 inch) in up to the scope of 304.8mm (12 inches).
Carpet is laid on the elastic buffer heelpiece 18, uses then and sandblast 20 or the similar top of grains of sand shape material processed strand or blade from high pressure nozzle 21 ejection.Thisly sandblast that the upper part of each strand splits into many shred 23 (see figure 6)s in the strand with making.These shreds are past to be extended laterally, thereby twines and weave in, forms intensive pad 24.
The power that sandblasts, the time span that depends on the inswept carpet surface that sandblasts is a speed, not only can divide blade, but also forces the sand of ejection to drop between the strand, and sand is deposited on the surface of carpet egative film.The sand bed 25 of Xing Chenging can remain on the egative film of carpet thus, should be held in place by the intensive shred pad intermeshing or that interweave that forms on the blade upper end by sand herein.
As an example, the height of blade on carpet surface is about 15.9mm (5/8) inch, and this is suitable for for the golf meadow, can make about 20%～30% the length on this height top split into shred.In this example, the about 1.6mm of strand (1/16 inch promptly about 0.07 inch) is wide, and about 0.051mm (0.002 inch) is thick, makes its cross section be about rectangle, and they bend at double place, form two blades, and assembles the wire harness into about 9～11 strands.Every like this wire harness constitutes 18～22 blades.The part on each blade top about 20% is divided into about four shreds.Therefore each wire harness has that many bottom of these shreds still is connected in blade body to about 70～80 shreds, and then stretch out to transverse direction its upper end, and twines with the shred of adjacent strand.The about 0.51mm of this shred (0.02 inch) is wide, is about 1.91mm～3.18mm (0.075～0.125 inch).
After the step that sandblasts, carpet is further handled in spraying water with high pressure of available high-pressure nozzle 28 ejections, and the pressure of this water spray for example is about 6.9 * 10
5～10.4 * 10
5(100～150 pounds/inch of Pascals
2), the effect that this has been sprayed water and has impacted further makes the shred that has divided separate, but the shred on the same strand is separated, the shred of the shred of a strand and adjacent strand is further twisted, bending and weave in, thereby make the pad that forms by the shred that interweaves more intensive.So just form more intensive and more uniform pad surface.
Brush can also be carried out with for example rotary brush 29 in this pad surface, is for further processing, and this brush is placed on the pad surface, can get the pad surface brush more even.Injection water or can one after the other carry out with the processing of brush brush, or carry out simultaneously, schematically illustrate as Fig. 5.
Meaningfully, the power that sandblasts can absorb by the elastic buffering pad below carpet fully, thereby prevents strand by backfin, or permanent deformation takes place, or by this reality of defeating.Be that strand sandblasts and still can remain on its stand up position after handling and maybe can return its stand up position in the end thereon.This stand up position is partly kept by the sand bed 25 of deposition.Simultaneously, strand and pad 24 make sand bed 25 fix in position.
The sand bed that is full of can fix in position, thereby the carpet that interweaves can roll, and is transported to the place, opens at this place again and is with sand bed to use.Can also be in the place of athletic competition field or at any workshop or the building site processing of sandblasting, in these places, with husky and spray water handle and the brush processing more convenient.Therefore the carpet after handling can no longer roll, and can directly be layered on the sport surface when needing, and sand still remains on its position, is using the place no longer to need other sand to carry out filling.
As mentioned above, concrete knitting wool carpet backing and installation system can change.Yet about 7600 deniers of its fiber number of the artificial turf that the example of the carpet that the golf meadow is used comprises, density is about 1.42kg/m
2(42 oz/yd
2), the about 15.9mm of fiber height (5/8 inch), adding thickness is the heelpiece of 12.7～50.8mm (1/2～2 inch).
Equally, the example of golf course passage ground carpet comprises about 7600 deniers' of fiber number artificial turf, the about 1.42～1.86kg/m of its density
2(42～55 oz/yd
2), the about 40.6～50.8mm of fiber height (8/5～2 inch) adds the thick heelpiece of 25.4mm (1 inch) at least.
The standard of weaving of another example of artificial turf is: fiber number is in 3600～10000 Denier ranges, with 13～22 pins/76.2 millimeter (13～22 pins/3 inch), 3/16 spacing (gage) and the about 1.15～2.20kg/m of density
2(34～65 oz/yd
2) material.
Can on market, buy the feed particles polypropylene material and be molded as the heelpiece that requires density.As an example, can be with the polypropylene GRANULES that has expanded of BASF, its trade mark is that NEOPOLENP buys, this trade mark is the registration mark of BASF.This material has 20.8,30.4,44.9kg/m
3(1.3,1.9,2.8 pounds/foot
3) three kinds of density can use, according to the reference that BASF provides, its trade mark is EPERNPP, model is PP45, PP30 and LBS20.When in suitable flat plate mold, just being molded into the density of required thickness at 24.0～48.1kg/m during at molded time known to the skilled and these granular materials of molding pressure condition lower mould
3(1.5～3 pounds/foot
3) the final heelpiece of scope.The flat plate pad that is molded into has the open structure of micropore.The concrete density of selecting can change according to concrete sports events.The density that for example has been found that the satisfaction that is used as the golf meadow is at about 37.8kg/m
3(2.36 pounds/foot
3) scope in.
The concrete grammar handled of being used to sandblast relates to the blaster of buying on the market and sandblasting under condition of high voltage.Pressure is preferably in 6.9 * 10
5～8.3 * 10
5(100～120 pounds/inch of Pascals
2) scope in, but pressure can change slightly, for example can be low to moderate about 5.5 * 10
5(80 pounds/inch of Pascals
2).Make the inswept to and fro carpet surface of nozzle, the sand drift of ejaculation is just sequentially beaten on the sub-fraction carpet.As if angle with respect to the injection sand drift on carpet plane can change, but preferred angle is about 70～80 °, and this angle can obtain very big effect in the shortest time.Distance between nozzle and the strand can change, and the equipment operator can select optimum distance by the splitting action of visualization injection stream.For example this distance can be in the scope of 101.6～127mm (4～5 inches), and this depends on the translational speed of the inswept carpet of nozzle.
Last artificial turf is specially adapted to golf course, for example is applicable to ground, meadow, inlet ground, ball seat ground and passage ground.This turf ground also can be used for tennis court, football field or association football pitch and with other sports ground on meadow.The example of these sports grounds is hockey field, meadow, croquet field, Grass bowling balls field, children's play area and baseball field etc.Very relevantly imitated sensation, effect or the resilience that produces by natural meadow ground motion place with the artificial turf ground that methods described herein are produced.The desired natural meadow of golf course and similar court ground has very relevantly been simulated on the last surface that interweaves.This turf can also be used on the ridge surface, in the garden or the deck, in these places, artificial turf can form heat insulation fluid-tight overburden.
Shown in Fig. 7 and 9, artificial turf can be used in the ball seat position of golf course, promptly is used in the zone of sportsman with the ball seat fulcrum ball, so that bat in this zone.Can be in these zones forming many slits 30 on the egative film of artificial turf carpet and on the heelpiece, so that receive the standard ball seat that inserts with hand.Slit 30 is dimensioned to and can inserts ball seat 3L with connecting airtight and make things convenient for the sportsman to find concrete slit location, can add color mark 32, for example adds suitable ink or paint mark on artificial turf ground.Fig. 7 illustrates has the artificial turf that shred forms pad, and Fig. 8 illustrates and do not have the turf of surface cushion shape.In both cases, this slit all can receive the ball seat of golf.
