Abstract

Disclosed is a silica felt, which is a glass fiber silica felt article. The utility model is characterized in that the waste silk of the glass fiber is machined through the processes of short cutting, opening and airlaying, the glass fiber gridding cloth is clamped between the two layers of the silica felt, and the silica felt is produced through the process of needling. The utility model has the advantages of no need of various adhesives, heat insulation, mildew and rot resistance, acid base resistance, acoustic insulation and filtration, electrical insulation, simple preparing process, high rate of finished products, abundant source of raw material, etc.

Description

Silica felt

The utility model is a kind of novel felt in the fiberglass products.

The glass fibre felt product of having produced at present all is a continuous glass fibre, felt product by continuous glass fibre production, or the short long fibre bundle of 50mm that is cut into, be deposited on the formed strip uniformly then, and apply the weak point that extraordinary bonding agent forms and cut felt, or adopt the centrifugal glass fibre of centrifugal method processing to add bonding agent.These glass mat scope of applications are little, the production cost height, and main is to produce a large amount of waste silks during continuous glass fibre is produced, and causes a large amount of raw material resources wastes, has caused massive losses to society.Cut felt and centrifugal felt owing to having adopted reasons such as bonding agent by the weak point of finished product continuous yarn production, make its good physical property and chemical stability not be fully used and bring into play.

The purpose of this utility model is exactly in order to make full use of the good heat insulation temperature tolerance of continuous glass fibre material, chemical stability, electric insulating quality, and sound insulation strainability, and the cotton felt of a kind of glass fibre novel silicon of design.

The cotton felted terxture of silicon described in the utility model, be to make it become the filament shape through machining process continuous glass fibre waste silk bundle, and through becoming the cotton felt of filament silicon after the air-laid process, sandwich the netted glass fibre knitmesh of one deck with between the silicon cotton wool felt of air lay two-layer, and make the cotton felt of two-layer filament silicon be three-dimensional state through acupuncture to combine with netted glass fibre knitmesh, thereby improved the tensile property of the cotton felt of novel silicon greatly, cleavability energy and easy to use.

Because the utility model accompanies knitmesh in the middle of two-layer felt, and through make behind the needling process between the fiber three-dimensional state and and medium between had good binding, overcome employing bonding agent felt, reduce the performance of glass fibre, therefore the cotton felt of this silicon need not the wrapper material that surface treatment just can be used as underground piping, the wrapping of steam-refrigerated pipeline, fields such as insulation decoration in the attic and filtration, sound insulation, dust suction can be prolonged service life of malthoid greatly by the malthoid base material of its substitute paper production.

The social benefit of the utility model maximum also is to make full use of the waste silk of the 30%-40% that is produced in the existing continuous glass fibre production, thereby has saved the raw material resources and the spent a large amount of energy of melt raw material, can obtain good economic benefit.

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing is the sectional schematic diagram of the cotton felt of novel silicon.

The cotton felt of filament silicon is through machining process with continuous glass fibre waste silk bundle as shown in drawings, make it become the filament shape, promptly overcome the profile defective of the smooth cylinder of fiber surface, make it that very dark young line (texturing) be arranged, have stronger cohesive force between fiber thereby make.The glass fibre of this filament shape is after the process air-laid process.Just become the felt product of different-thickness and width, the felt product of this moment has lower intensity and bigger extension.

With reference to accompanying drawing, wherein 1 is glass fibre knitmesh, and it plays the tension booster action in the centre.The 2nd, the glass filament of in-plane, after the air lay most filament this shape exist.The 3rd, through the glass filament after the acupuncture, it plays the connection effect at thickness direction, and connects by knitmesh and another piece, in fact the cotton of the silicon after acupuncture felt at three-dimensional state in conjunction with as a whole.

Implement the utility model, only need to obtain the glass fibre silicon cotton felted terxture of different-thickness, fabric width and different qualities by newly-designed Process configuration processing, required auxiliary equipment both can have been made also available homemade same category of device by oneself and substituted, its raw material sources is abundant, manufacture craft is simple, production cost is low, so have good development prospect.

Claims

The cotton felt of a kind of novel silicon is made of the cotton felt of filament silicon, it is characterized in that: accompany the netted glass fibre knitmesh of one deck in the cotton felt of two-layer filament silicon, and make the cotton felt of two-layer filament silicon be three-dimensional state with netted glass fibre knitmesh through acupuncture to combine.
