The utility model discloses tensile strength is big, and the dust containing capacity is high, and the filter effect is good, and ventilative effectual and the cost of manufacture is more cheap.
Description
Technical field
The utility model belongs to filter cotton technical field, relates in particular to a kind of air filtration cotton.
Background technology
The cotton general employing of traditional air filtration two kinds of structures, one is common filter cotton, and its fiber pore size is basically identical; Another kind is that the filter cotton increasing form is presented in fiber aperture.It is little to there is tension intensity in these two kinds existing filtration Cottonopolis, and filter effect is general, and dust containing capacity is limited, and ventilative power is little, the problem that the large cost of grammes per square metre is high.If improvement tension intensity, generally also to adopt extra impregnation processing technology to filter cotton, solve the little problem of tension intensity in this way although adopt, improve production cost, reduce operating efficiency.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of air filtration cotton.
Its concrete technical scheme adopted is as follows:
A kind of air filtration is cotton, includes stratification of wind, air outlet layer, the first glass fiber mesh and the second glass fiber mesh; Described first glass fiber mesh is entering between stratification of wind and air outlet layer; Described air outlet layer is between the first glass fiber mesh and the second glass fiber mesh; Described enter stratification of wind by the 7D fiber of 40%, the 4D fiber of 30% and 30% 3D fiber form; Described air outlet layer by 30% 7D fiber, the 4D fiber of 40%, the 3D fiber of 20% and 10% 1.2D fiber form.
By adopting this technical scheme: formed with crude fibre the air filtration cotton evacuated and enter stratification of wind, formed the cotton air outlet layer of fine and close air filtration with fine fibre and superfine fibre.To utilize into stratification of wind grammes per square metre than characteristic that is little, Rong Chenduo, improve the overall dust containing capacity of filter cotton, reduce overall grammes per square metre ratio; Meanwhile, utilize the feltwork structure of air outlet layer, realize the filtration completely of more than 0.01 micron particle diameter dust, ensured the improvement of filter cotton strainability.Utilize the first glass fiber mesh and the second glass fiber mesh to enhance the tension intensity of filter cotton, thus process without the need to extra impregnation, reduce production cost.
Preferably, described in above-mentioned air filtration cotton, the first glass fiber mesh and the second glass fiber mesh are all 11 order glass fiber mesh, and the thickness of described first glass fiber mesh is 5 ~ 25 μm, and the thickness of described second glass fiber mesh is 15 ~ 35 μm.Described enter stratification of wind enter stratification of wind laying by 12 stratons and form; Described air outlet layer forms by 12 straton air outlet layers are stacking; Described enter the thickness of stratification of wind be 13 ~ 15mm, the thickness that each son enters stratification of wind is 1.08 ~ 1.25mm; The thickness of described air outlet layer is the thickness of each sub-air outlet layer of 8 ~ 10MM is 0.67 ~ 0.83MM.
Compared with prior art, the product tension intensity that the utility model provides is large, and dust containing capacity is high, good filtration effect, ventilative effective and cost of manufacture is more cheap.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1, eliminates son and enter stratification of wind and sub-air outlet layer in accompanying drawing;
In above-mentioned accompanying drawing each component names and component names corresponding relation as follows:
1, stratification of wind is entered; 2, air outlet layer; 3, the first glass fiber mesh; 4, the second glass fiber mesh.
Detailed description of the invention
Below in conjunction with instantiation, the utility model is further described.
Embodiment 1 of the present utility model as shown in Figure 1:
A kind of air filtration is cotton: include stratification of wind 1, air outlet layer 2, first glass fiber mesh 3 and the second glass fiber mesh 4; Described first glass fiber mesh 3 is entering between stratification of wind 1 and air outlet layer 2; Described air outlet layer 2 is between the first glass fiber mesh 3 and the second glass fiber mesh 4; Described enter stratification of wind 1 by the 7D fiber of 40%, the 4D fiber of 30% and 30% 3D fiber form; Described air outlet layer 2 by 30% 7D fiber, the 4D fiber of 40%, the 3D fiber of 20% and 10% 1.2D fiber form.Wherein, described first glass fiber mesh 3 and the second glass fiber mesh 4 are all 11 order glass fiber mesh, and the thickness of described first glass fiber mesh 3 is 5 ~ 25 μm, and the thickness of described second glass fiber mesh 4 is 15 ~ 35 μm.Described enter stratification of wind 1 enter stratification of wind 11 laying by 12 stratons and form; Described air outlet layer 2 forms by 12 straton air outlet layers 21 are stacking; Described enter the thickness of stratification of wind 1 be 13 ~ 15mm, the thickness that each son enters stratification of wind 11 is 1.08 ~ 1.25mm; The thickness of described air outlet layer 2 is the thickness of each sub-air outlet layer 21 of 8 ~ 10MM is 0.67 ~ 0.83MM.
Carry out test with the product of embodiment 1 and the like product on existing market to compare:
Its dust containing capacity of like product on existing market is 400g/ ㎡.And the dust containing capacity of the product of embodiment 1 reaches 500g ~ 550g/ ㎡.Its initial resistance of like product on existing market is 25pa ~ 30pa, and whole resistance is 400pa.And its initial resistance of the product of embodiment 1 20pa ~ 25pa, whole resistance is 450pa ~ 500pa.Obviously, the product of embodiment 1 has better dust containing capacity and more outstanding tension intensity.
