A diameter of 0.12~the 0.13mm of organizine of fine groove plain weave net, the thickness of the fine groove plain weave net for 0.194mm~
0.216mm。
The present invention is realized to be more preferable, may further be：The braiding mesh number in tram direction is in the fine groove plain weave net
710 mesh/25.4mm~730 mesh/25.4mm, the braiding mesh number in its organizine direction is 82 mesh/25.4mm~85 mesh/25.4mm.
The present invention is realized to be more preferable, may further be：The a diameter of 0.125mm of organizine of the fine groove plain weave net, its
The a diameter of 0.043mm of tram, its organizine direction braiding mesh number be 84 mesh/25.4mm, its tram direction braiding mesh number be 720 mesh/
25.4mm, its net thickness are 0.211mm.
Beneficial effects of the present invention：Optimized based on the weaving manner of fine groove plain weave net, select and pass through special heat
The super-duplex stainless steel material of processing, compared to more general stainless steel wire, the intensity of its stainless wire mesh add 20% with
On, it is achieved thereby that the arrangement of direction of warp and weft more crypto set, due to material reason so that fine groove plain weave in the present invention
The resistance to corrosion of net is also obviously improved, the organizine density increase by more than 6% of finished product mesh grid so that fine groove in the present invention
The netted interception angle of plain weave net increases more than 2 °, and net structure angle more they tends to equilateral triangle, improves nominal hole
Footpath envelope shape, effectively increases filtering precision；Tram direction density is also increased in the range of more than 3.5%, 50.8mm
The sum of tram diameter improves 14%, so that tram has been locked in the deformation during knitmesh, makes finished product web frame double to stablize.
Brief description of the drawings
Fig. 1 illustrates the positive structure diagram of fine groove plain weave net in the present invention；
Fig. 2 illustrates the overlooking the structure diagram of fine groove plain weave net in the present invention.
In figure, 1 is tram；2 be organizine.
Embodiment
Elaborate below in conjunction with the accompanying drawings to the present invention.
