Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example (b): as shown in fig. 1-4, the coated glass fiber woven filter material of the utility model comprises a base fabric layer 1, wherein a polytetrafluoroethylene impregnation treatment layer 2 covers the surface of the base fabric layer 1, polytetrafluoroethylene coatings 3 cover the bottom surface of the base fabric layer 1 and the surface of the polytetrafluoroethylene impregnation treatment layer 2, the base fabric layer 1 comprises a glass fiber base layer 10, a dust facing layer 5 covers the surface of the glass fiber base layer 10, a gas purification layer 4 is arranged on the bottom surface of the glass fiber base layer 10, and an antistatic material covers the surface of the polytetrafluoroethylene coating 3.

Wherein, it is fibrous material to meet dust layer 5 and air-purifying layer 4, through meeting dust layer 5 and air-purifying layer 4, can further purify dust in the environment.

Wherein, a tear-resistant warp knitted fabric 6 is woven between the glass fiber base layer 10 and the air purifying layer 4.

Wherein, the outside parcel of base cloth layer 1 has bordure 7, a pair of fixture block 8 is installed to one side of borduring 7, a pair of draw-in groove 9 has been seted up to the opposite side of borduring 7, through fixture block 8 and draw-in groove 9, convenient to use person installs a plurality of filter materials, and then improves the filter area of filter material.
