Abstract
The cotton felted terxture of glass fibre silicon, be to adopt glass fibre waste silk (or precursor) to cut through too short, disperse air lay, technology such as acupuncture and the felt product that satisfies needs such as all kinds of insulations, waterproof, anti-mildew and rot, heat-resisting, acid and alkali-resistance, sound insulation, filtration, electric insulation made.Its processing technology is simple, the yield rate height, and cost is low, and product-use is extensive, and the raw material source is abundant and solved the waste silk outlet, has good economic benefit and social benefit.
Description
The present invention is a kind of new processing method and the cotton felt material of being made by this method of novel silicon in the fiberglass products processing.
The cotton felted terxture of the glass fibre silicon of having produced at present, all be that the centrifugal spray of continuous glass fibre is cotton, or it is long that the continuous glass fibre bundle is cut into 50mm, uniform settlement is on formed strip then, and apply extraordinary bonding agent and form the short felt of cutting, and the waste silk of generation 30-40% in the continuous glass fibre production, and also produce a large amount of leftover bits and pieces in the production of articles, these waste silks and leftover bits and pieces not only cause the waste of a large amount of raw material resourceses and the energy, and become the burden of factory, caused very big loss to the wealth of society.
The present invention adopts advanced air lay new technology, so length to fibre bundle, the thickness of fiber does not all have fastidious, it is nearly 100% that row yielding reaches, and the purpose of invention is to make the cotton felt of the novel silicon with multiple premium properties in order to develop the waste silk and the leftover bits and pieces in the production of articles that are produced in the existing continuous glass fibre production.
The cotton felted terxture of silicon of the present invention mainly is to make it be dispersed into the filament shape through machining process in the bundle fiber waste silk.Be about to continuous glass fibre waste silk (also available precursor) through chopping machine, reel behind air lay unit and the needing machine and pack, promptly can be made into the cotton felt of glass fibre silicon of all size, its technological process is as follows:
As Fig. 1 is the manufacture craft procedure chart of the cotton felted terxture of silicon, the first step, raw material waste silk feeding chopping machine, be cut into the staple fibre bundle of fixed length by chopping machine, the staple fibre Shu Zidong that downcuts slips into second step process, it is the air lay unit, in the air lay unit, fibre bundle is through disperseing, operations such as shredding, after air lay becomes cotton shape glass kinetodesma felt, this operation requires to carry out the single face thorn according to difference when entering third part, the goods acupuncture of two-sided thorn and two-layer folder base cloth just can be used for various needed occasions through the packing of reeling again.
Fig. 2 introduces the local photography of the section enlarged drawing (amplifying 20 times) that the continuous glass fibre weak point is cut felt, and its fiber exists with pencil, and this kind weak point is cut felt many shortcomings that are difficult to overcome.Fig. 3 is that local macrophotography (amplifying 20 times) this kind fiber of the cotton felt of novel tape base cloth silicon of technology making of the present invention exists with the filament shape, and the surface is texturing, with the three-dimensional state weave in, purposes is widely arranged between the filament so have good characteristic by the cotton felted terxture of the made glass fibre silicon of the present invention.Fiberglass products itself has insulation, characteristic such as high temperature resistant, corrosion-resistant, and defective such as the present invention has overcome continuous glass fibre bundle smooth surface, and the silk sense is strong, thereby make its product have more good adsorption, the performances such as filtration, insulation of gathering dust.Fluffy in addition, the filament shape glass fibre that disperses, make it be three-dimensional state through needling process and have good binding, it is poor to medium osmosis to have overcome continuous glass fibre, both are in conjunction with bad, cause the low weakness of goods cleavability energy, make itself and all kinds of medium have good binding, the reduction and the process equipment that adopt product properties behind the bonding agent felt have been overcome again, the increase of cost, and this product-novel silicon cotton felt need not surface treatment and just can be used for doing laminated product, the base material of asphalt water-proof coiled material etc., the anticorrosioning wrapping material of underground piping, the separate layer of building such as concrete-bridge and highway, the base material of PVC coiled material also can be widely used in steam simultaneously, the wrapping of refrigeration piping, the insulation on roof, fields such as upholster.Improved the service life that leakproof, anticorrosion, anti-performance such as go rotten have prolonged malthoid greatly by the malthoid base material of its substitute paper production.
The social benefit of maximum of the present invention also is the waste silk of the 30-40% that the existing continuous glass fibre production of absolutely utilization is produced, thereby saved raw material resources greatly and consumed useless a large amount of energy with the fusion raw material, remove the problem that continuous glass production factory waste silk becomes to suffer from, can obtain good economic benefit and social benefit.
The present invention only needs the adjusting process parameter can obtain the cotton felted terxture of glass fibre silicon of different-thickness amplitude and different characteristics.And its raw material sources is abundant, and manufacture craft is simple, and production cost is low, so implementary value is arranged very much.
Claims (3)
1, the cotton felted terxture of a kind of air lay new technology processed glass fiber silicon is characterized in that:
A, the continuous glass fibre waste silk is cut through too short, air lay makes smooth fibre bundle become the strong filament shape glass wool of the feel of wool, also can sandwich continuous glass fibre or continuous glass fibre fabric, make the cotton felted terxture of glass fibre silicon of Different Weight, different fabric widths again through acupuncture at last.
B, through the cotton felted terxture of the filament shape silicon after the acupuncture have good three-dimensional structure and with the adsorptivity of medium.
2, processing technology according to claim 1 is characterized in that having utilized to greatest extent the waste silk that is produced in the present continuous glass fibre production.
3,, can be widely used in aspects such as insulation, waterproof, anti-pollution, anti-mildew and rot, heat-resisting, acid and alkali-resistance, sound insulation, filtration, electric insulation according to the cotton felted terxture of the silicon of the described new technology of claim 1 processing.
