Description
Technical field
The invention belongs to flood control field of harnessing the river, be specifically related to a kind of composite water absorbing expanding bag.
Background technology
Existing flood control expanding bag is all the independent structure be not connected of interior outer bag, easily make inner bag turn to or cuddle up in a heap to squeeze in a corner of outer bag in processing, handling process, thus expanded granular when causing using in bag is because inner bag can not launch completely and be compressed on an angle, need manually to go again to stir, also extend Bulking Time during expanding bag chance water, have a strong impact on the efficiency of flood control of harnessing the river.The expanded granular water suction of existing its inside of Flood control bag simultaneously can only expand about 50 times, as expansion rate is low, poor water retention property, because particle is not homodisperse in bag, but squeeze in a corner, water suction is scattered, and when causing absorbing water, Bulking Time lengthens, and general needs about 10 minutes could complete distending.
Summary of the invention
The object of the invention is to provide a kind of composite water absorbing expanding bag for solving the problems of the technologies described above.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
A kind of composite water absorbing expanding bag, comprise outer bag and inner bag, also comprise the polymer water uptake expansion agent particle be loaded in inner bag, at least part of bag of described inner bag and outer bag are connected the anti-bias transfer part, location being formed and position relative to outer bag for internal bag.
Anti-bias transfer part, location is set and can ensures relative between inner bag with outer bag can not displacement, ensure that inner bag is in the open and flat state opened always.
As preferably, described outer bag is gunnysack or Polywoven Bag, and described inner bag is spunlace non-woven cloth bag, and described outer bag is provided with rib.
Bag is arranged rib to can be used for increasing bag intensity, ensure that bag can not burst, longer service life.
As preferably, described rib is encrypt the encryption reinforcing rib of arranging and being formed at this position by the litzendraht wire of outer bag.
Rib directly encrypts the position litzendraht wire density increase of braiding i.e. outer bag at rib by litzendraht wire, and the more additional reinforcing rib of its intensity is higher, processes more convenient simultaneously.
As preferably, described outer bag edge is provided with joining edge, and anti-bias transfer part, described location is be located at inner bag gulde edge inner bag limit laminating stitching with the joining edge of outer bag.
As preferably, described inner bag gulde edge is the local segment or all on inner bag limit, inner bag gulde edge place.
As preferably, described inner bag gulde edge is located on three inner bag limits adjacent successively on inner bag or relative two inner bag limits.
As preferably, the outer bag locking limit that described joining edge comprises outer bag gulde edge and formed by outer bag gulde edge outer end reflexed, the inner bag locking limit that described inner bag gulde edge comprises inner bag gulde edge and formed by inner bag gulde edge outer end reflexed, described inner bag gulde edge and joining edge are double-deck limit, and inner bag gulde edge is located between two-layered suture limit.
Greatly strengthen outer bag and inner bag in the intensity of seal location by the cooperation on gulde edge and locking limit, prevent quick-fried bag, done flood control results high, extend application life.
As preferably, described polymer water uptake expansion agent particle is high-molecular polythene water absorbing resin particle.
High-molecular polythene water-absorbing resin it there is the high absorbent function of the heavy hundreds of of absorptance self to several thousand times of water, and water retention property is excellent, becomes hydrogel once imbibition, even if pressurization is also difficult to water to separate.
As preferably, one or two inner bag face of described inner bag is furnished with one deck viscous force and is less than polymer water uptake expansion agent particulate water absorbent and expands the thin adhesive layer of the expansion tension produced, described polymer water uptake expansion agent particle is distributed on described thin adhesive layer.
As preferably, an inner bag face of described inner bag is furnished with one deck thin adhesive layer.
In bag, arranging of thin adhesive layer ensures that polymer water uptake expansion agent particle can scatter always equably, and during use, bag can be opened by even inflation rapidly, shortens Bulking Time, cloth one deck thin adhesive layer, thus ensures that water can infiltrate in bag quickly as much as possible.
In sum, the present invention has following beneficial effect:
1, the application substantially increases the expansion efficiency of expanding bag by the setting of anti-bias transfer part, location, thin adhesive layer and high-molecular polythene water absorbing resin particle, generally can complete bag at two to four minutes evenly fully to expand, the setting of the dual lock seaming of bag simultaneously and rib also can improve the intensity of bag greatly, extends the application life of bag.
2, the application's structure is simple, easy to process, and cost is low.
