Abstract
The utility model discloses an improved glass fiber filter felt which comprises woven fabrics and is characterized in that the periphery of the woven fabrics is covered with a silicane coupling agent layer, a water-proofing agent layer is coated on the periphery of the silicane coupling agent layer, thickness of the woven fabrics is bigger than that of the silicane coupling agent layer, thickness of the silicane coupling agent layer is bigger than that of the water-proofing agent layer, and the woven fabrics are woven by alkali-free glass fiber and superfine polytetrafluoroethylene yarn in a composite mode. The improved glass fiber filter felt has the advantages of being good in heat stability, good in resistance performance to chemical corrosion gas, good in inoxidizability, high in filter accuracy, superior in temperature endurance, and strong in tensile strength. By means of the adoption of surface filtration, dust stripping performance is good, dust is easily removed, dust removing frequency of a dust remover is reduced, and service life of filter materials are prolonged.
Description
Technical field
The utility model relates to the fibre field, relates in particular to a kind of improved glass fibre filter felt.
Background technology
At present, in some occasions that the filtrating smoke dust temperature is higher, smoke components has more complicated, filtering material such as uses such as iron-smelter, garbage burning factory, blast furnace gas length, the temperature of particle is higher, to filtering material heat endurance, chemically-resistant gas attack and filtering accuracy have relatively high expectations.The filtering material that now uses, the heat endurance of product, chemically-resistant gas attack, filtering accuracy are relatively poor, and resistance to elevated temperatures is poor, and service life is short, draws thus common filtering material and is difficult to satisfy its requirement.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this utility model provides a kind of improved glass fibre filter felt.
The technical solution adopted in the utility model is:
A kind of improved glass fibre filter felt comprises woven fabric, and the periphery of described woven fabric is coated with the silane coupling agent layer, and described silane coupling agent layer periphery is coated with the waterproofing agent layer.
The thickness of described woven fabric is greater than the thickness of silane coupling agent layer, and the thickness of described silane coupling agent layer is greater than the thickness of waterproofing agent layer.
Described woven fabric is by alkali-free glass fibre and compound being made into of ultra-fine polytetrafluoroethylene (PTFE) yarn.
The utility model has the advantages that: Heat stability is good, the chemically-resistant gas attack is good, good in oxidation resistance, filtering accuracy is high, temperature tolerance is superior, and hot strength is high, adopts surface filtration, and the stripping performance of dust is good, easy-to-clean ash, the deashing frequency of reduction deduster, the service life of having improved filtrate.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, woven fabric, 2, the silane coupling agent layer, 3, the waterproofing agent layer.
The specific embodiment
As shown in Figure 1, a kind of improved glass fibre filter felt of the present utility model, comprise woven fabric 1, the periphery of described woven fabric 1 is coated with silane coupling agent layer 2, described silane coupling agent layer 2 periphery are coated with waterproofing agent layer 3, the thickness of described woven fabric 1 is greater than the thickness of silane coupling agent layer 2, the thickness of described silane coupling agent layer 2 is greater than the thickness of waterproofing agent layer 3, and described woven fabric 1 is by alkali-free glass fibre and compound being made into of ultra-fine polytetrafluoroethylene (PTFE) yarn, Heat stability is good, the chemically-resistant gas attack is good, good in oxidation resistance, filtering accuracy is high, and temperature tolerance is superior, hot strength is high, adopt surface filtration, the stripping performance of dust is good, easy-to-clean ash, reduce the deashing frequency of deduster, the service life of having improved filtrate.
