Abstract
The utility model provides a glass fiber reinforced base strain gauge, which comprises a glass fiber reinforced base (1) and a metal foil (2). The utility model is characterized in that a mucilage layer (4) is arranged between the glass fiber reinforced base (1) and the metal foil (2). The mucilage layer (4) not only strengthens the glass fiber reinforced base (1), but also enables the peeling strength of the strain gauge to be greatly improved, at the same time, the anti-humid hot property, the creeping resistance, the zero restoring ability and the reliability of the strain gauge are also obviously improved, thereby the utility model is suitable for the occasions which require medium temperature and higher sensor accuracy.
Description
Technical field
The utility model relates to a kind of strain ga(u)ge, particularly a kind of paper tinsel formula glass fabric substrates strain ga(u)ge.
Background technology
At present, known foil resistance strain gauge be by the electronic isolation material as substrate, xerox etching technique with photoetching and on the metal foil of compacting by rolling, form sensitive grid, form the weldering end in the sensitive grid rear end and make.The base material of strainometer has paper, epoxies, phenolic, polyesters, acetals, polyimide, glass fabric impregnation, sheet metal etc.What the foil resistance strain gauge of these types of substrates all adopted is the process that the liquid glue no-load solidify to form the strainometer substrate, and the structure that forms product is one deck substrate and layer of metal paper tinsel, or one deck substrate and layer of metal paper tinsel and sealant.In test and using, these strainometers exist obviously that peel strength is low, the heat resistance poor performance, creep disperses and return deficiency such as zero instability, can't satisfy accurate LOAD CELLS, the weighing apparatus needs with sensor, force transducer, Industry Control, stress analysis.Tracing it to its cause, is owing to make the process defectiveness of product on the one hand, is because the existing structure of strainometer causes on the other hand.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, to propose a kind of fiberglass reinforced substrate strainometer by improving the structure of paper tinsel formula glass fabric substrates strain ga(u)ge.
The technical scheme that realizes above-mentioned purpose is: the fiberglass reinforced substrate strainometer, comprise glass fabric substrates, metal forming, and it is characterized in that an adhesive-layer is arranged between glass fabric substrates and metal forming.
Above-mentioned adhesive-layer has not only strengthened glass fabric substrates, and the peel strength of strainometer is greatly improved, the heat resistance performance of strainometer, creep, return zero, stability also is significantly improved.
Description of drawings:
Fig. 1 is the structure section synoptic diagram of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. glass fabric substrates, 2. metal forming, 3. sealant, 4. adhesive-layer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment illustrated in figures 1 and 2 is a kind of product with protective layer on essential structure of the present utility model basis.Essential structure as the utility model fiberglass reinforced substrate strainometer is made up of glass fabric substrates 1, metal forming 2 and adhesive-layer 4, and adhesive-layer 4 is with glass fabric substrates 1 and metal forming 2 secure fit.In the present embodiment, an adhesive-layer 4 is also arranged between metal forming 2 and the sealant 3.
In the process of making above-mentioned strainometer, at first select for use epoxy resin and non-woven glass fibre cloth to carry out impregnation, glass fabric impregnation thin plate is made in curing through lamination, it is glass fabric substrates 1, its thickness range is 20～40 μ m, then with epoxy resin or phenolic aldehyde-epoxy resin as bonding agent, metal forming 2 and glass fabric substrates 1 are bonded together, carry out lamination once more, the thickness of adhesive-layer 4 is 2～5 μ m.The thickness range of strainometer sensitive grid is 2.5～5 μ m, about 24.5～50 μ m of whole strainometer thickness.
The utility model fiberglass reinforced substrate strainometer can increase sealant 3 by customer requirements, and an adhesive-layer 4 is also arranged between metal forming 2 and the sealant 3, and the strainometer general thickness after the sealing can reach 46.5～75 μ m.
The heat resistance performance of the said goods, creep, return zero, strainometer that stability is better than existing in the market phenolic, acetals, other every indexs also all satisfy GB/T13992-92 " strain ga(u)ge " GB A level product requirement, are particularly useful for the occasion that middle temperature, sensor accuracy are had relatively high expectations.
Claims (3)
1. a fiberglass reinforced substrate strainometer comprises glass fabric substrates (1), metal forming (2), it is characterized in that: between glass fabric substrates (1) and metal forming (2) adhesive-layer (4) is arranged.
2. according to the described fiberglass reinforced substrate strainometer of claim 1, it is characterized in that: the thickness range of described glass fabric substrates (1) is 20～40 μ m, and the thickness of adhesive-layer (4) is 2～5 μ m, about 24.5～50 μ m of whole strainometer thickness.
3. according to claim 1 or 2 described fiberglass reinforced substrate strainometers, it is characterized in that: a sealant (3) is arranged on metal forming (2), between metal forming (2) and the sealant (3) adhesive-layer (4) is arranged also.
