Abstract
The utility model discloses a kind of composite fluid filter felt, comprise flannelette napped fabric layer, PTFE coating layer and base cloth layer, described PTFE coating layer is set to two-layer, and two-layer PTFE coating layer is bonded in respectively upper surface and the lower surface of base cloth layer, wherein the bonding flannelette napped fabric layer in the upper surface of one deck PTFE coating layer.Compared with prior art, the utility model can first filter the large particulate matter in liquid by flannelette napped fabric layer, then filters through the essence of PTFE overlay film, and PTFE overlay film has the feature of antiacid alkali resistant, anti-various organic solvents, has strengthened service life of the present utility model.
Description
Technical field
The utility model relates to filter felt technical field, particularly a kind of composite fluid filter felt.
Background technology
At present, in the production of some corrosive liquids, need to use filter felt and filter, but more existing filter felt strainabilities are poor, and service life is short, brings huge challenge to production cost.
Summary of the invention
The purpose of this utility model is the composite fluid filter felt that a kind of good filtration effect, long service life will be provided.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of composite fluid filter felt, comprise flannelette napped fabric layer, PTFE coating layer and base cloth layer, described PTFE coating layer is set to two-layer, and two-layer PTFE coating layer is bonded in respectively upper surface and the lower surface of base cloth layer, wherein the bonding flannelette napped fabric layer in the upper surface of one deck PTFE coating layer.
Compared with prior art, the utility model can first filter the large particulate matter in liquid by flannelette napped fabric layer, then filters through the essence of PTFE overlay film, and PTFE overlay film has the feature of antiacid alkali resistant, anti-various organic solvents, has strengthened service life of the present utility model.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, is used for explaining the utility model in illustrative examples and the explanation of this utility model, but not as to restriction of the present utility model.
A kind of composite fluid filter felt as shown in Figure 1, comprise flannelette napped fabric layer 1, PTFE coating layer 2 and base cloth layer 3, described PTFE coating layer 2 is set to two-layer, and two-layer PTFE coating layer 2 is bonded in respectively upper surface and the lower surface of base cloth layer 3, wherein the bonding flannelette napped fabric layer 1 in the upper surface of one deck PTFE coating layer 2.
Operation principle of the present utility model: first filter the large particulate matter in liquid by flannelette napped fabric layer 1, then filter through the essence of PTFE overlay film 2, PTFE overlay film 2 has the feature of antiacid alkali resistant, anti-various organic solvents, has strengthened service life of the present utility model.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model, within all falling into protection domain of the present utility model.
