Abstract
Bobbins is stretched the utility model discloses a kind of high-temperature-resistant, tensile, including base material, opposite end is serrated on base material, the opposite end being serrated on base material when base material winds to form cylinder to form joint portion for edge fit is engaged, and the two of joint portion faces out and be sequentially provided with Teflon glass coating cloth, fep film.The utility model has tensile break strength high, resistance to certain high temperature, the performance without compression deformation and good permeability.Its long service life, scrap (bridge) interface smooth-going, substantially increases the security in glass fabric production process.
Description
Technical field
The utility model is related to the bobbins in alkali-free glass fibre production process, and in particular to a kind of high-temperature-resistant, tensile is stretched
Bobbins.
Background technology
Alkali-free glass fibre is a kind of Inorganic Non-metallic Materials of excellent performance, and species is various, and advantage is good insulating, resistance to
Hot strong, corrosion resistance is good, high mechanical strength.It is with silicate powder as raw material through high temperature melting, wire drawing, doff, weave cotton cloth
It is manufactured into etc. technique, to twenties meters microns, every bundle fiber precursor is all by hundreds of for a diameter of several microns of its monofilament
Even thousands of monofilament compositions.Glass fibre, and glass fabric is typically used as the reinforcing material in composite, and be electrically insulated material
The national economy every field such as material and heat-insulating material, circuit base plate.
During glass fibre is produced, glass fibre raw yarn need to be wound on the wire-drawing machine head that runs at high speed " around
Silk is wound on silk cylinder ", then is dried together with " drying oven " that bobbins sends into 140 °C or so is interior, finally doffed
Precursor is moved back into solution from bobbins on machine and is plied to finished product yarn.In above-mentioned technical process, bobbins will undergo rotation at a high speed, high
Temperature baking, the impact of the adverse circumstances such as chemical attack of yarn size, therefore, bobbins must have enough fracture strengths, resistance to
The need for hot, dimensional stability, gas permeability etc. are to meet Reusability.
Existing bobbins has three major types, and one kind is made up of high-quality wood-fibred paper, because of low intensity, can only recycle number
It is secondary, and easily there is squib, the production even generation of casualty accident are interrupted, and paper is made up of wood pulp, expends substantial amounts of natural resources,
High cost.It is made up of polymer composite fabric folder rubber layer for second, complex process is easily aging, and incision easily takes off yarn,
Interrupt glass strand and cause the generation of " STOP " accident, the size residue after meeting absorption solidification is used for multiple times and connection glass is glued
Precursor, causes to move back that solution is bad, and service life is limited, and the third is after being made into cloth by conventional glass fiber yarn, then impregnates painting
Layer Teflon emulsion, forms at overlap edge through HTHP bonding, although than the first, second product has very this product
Many advantages, but also there is bobbins fracture strength not enough, there is the problem of seam at scrap (bridge), so as to influence service life.
The content of the invention
The utility model is regarding to the issue above, there is provided a kind of high-temperature-resistant, tensile stretches bobbins, by by base material relative two
End is designed as being engaged the zigzag of edge fit, edge fit is engaged the joint portion to be formed covering using adhesive linkage so as to be made around
Silk cylinder, it has tensile break strength high, resistance to certain high temperature, the performance without compression deformation and good permeability.Long service life, scrap (bridge)
Interface is smoothed out, the characteristics of substantially increase production security.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of high-temperature-resistant, tensile stretch around
Silk cylinder, it is characterised in that including base material, opposite end is serrated on base material, in saw on base material when base material winds to form cylinder
The opposite end of dentation to form joint portion for edge fit is engaged, and the two of joint portion faces out and be sequentially provided with Teflon glass coating
Cloth, fep film.
As the preferred of such scheme, the glass fabric that described base material is knitted to form for high intensity raw yarn, the glass
The base material wrapped up by Teflon emulsion coating is formed after fiber cloth dip-coating Teflon emulsion.
As the preferred of such scheme, a diameter of 6 microns of raw yarn.
The beneficial effects of the utility model are：The utility model has tensile break strength high, resistance to certain high temperature, becomes without contracting
The performance of shape and good permeability.Its long service life, scrap (bridge) interface smooth-going, in substantially increasing glass fabric production process
Security.
Brief description of the drawings
Fig. 1 is expanded schematic diagram of the present utility model；
Fig. 2 is the schematic diagram of joint portion when Fig. 1 winds to form cylinder.
Specific embodiment
With reference to embodiment, specific embodiment of the present utility model is further described.
As shown in Figure 1-2, a kind of high-temperature-resistant, tensile stretches bobbins, including base material 1, and opposite end is serrated on base material,
The opposite end being serrated on base material when base material winds to form cylinder to form joint portion 2, the two of joint portion for edge fit is engaged
Face out and be sequentially provided with Teflon glass coating cloth, fep film, described Teflon glass coating cloth bonding is covered institute by fep film
The joint portion stated.
Wherein, adhesive linkage is covered in joint portion two sides through high temperature hot pressing bonding.
Described base material is the glass fabric that high intensity raw yarn is knitted to form, the glass fabric dip-coating Teflon emulsion
The base material wrapped up by Teflon emulsion coating is formed afterwards.
A diameter of 6 microns of raw yarn.
For a person skilled in the art, the technical scheme described in foregoing embodiments can still be repaiied
Change, or equivalent is carried out to which part technical characteristic, all within spirit of the present utility model and principle, that is made is any
Modification, equivalent, improvement etc., should be included within protection domain of the present utility model.
