Abstract
The invention relates to a strain gauge water-proof sealing method and a structure thereof. A strain gauge is adhered on the surface of a test point of a tested structure; a measuring lead wire is welded on a wiring terminal of the strain gauge; and an SB-type water-proof sealant, an aluminum foil tape and waterproof paint are covered on the upper part of the strain gauge sequentially so that the strain gauge and the peripheral area thereof are covered completely. The method and the structure can shorten the sealing operation time of the strain gauge greatly, wherein the operation time for a single test point is not more than 5 minutes; because the multi-seal of the water-proof paint, the aluminum foil tape and the SB-type water-proof sealant, the water-proof sealing effect can be ensured for a long time; and the water-proof sealing effect can last at least more than half a year in an seawater environment with high corrosiveness.
Description
Technical field
The present invention relates to the detection technique field, especially the waterproof sealing method of foil gauge.
Background technology
In fields such as boats and ships and oceanographic engineerings, in order to examine underwater intensity of structure and stability, often need being carried out stress-strain test by geodesic structure, foil gauge need be fixed on tested body structure surface during test and realize water-tight, need to keep good insulation performance between foil gauge, measurement lead and the structured material, resistance need be greater than 100M Ω.Encapsulating method commonly used adopts thin crown cap of soldering or glue to cover two kinds of bondings usually, the method of the thin crown cap realization of soldering sealing is disclosed as patent of invention 03137103.5 " foil gauge deep-sea insulating method and device ", but this method is of limited application, remove and the heavy industry trouble, so the general method that adopts glue to cover bonding more.Concrete method of operating is to adopt instant drying adhesive that foil gauge is firmly sticked on tested body structure surface earlier, foil gauge is connected upward measurement lead, coat 703 silicon rubber at the jointing place then, owing to be the liquid state before 703 adhesive curings, and need 24 hours set time, in solidification process, most 703 glue have all trickled, and generally need through just reaching the effect of basic sealing for 5～6 times repeatedly after the gluing, and the running time is very long, especially under the more urgent situation of time ratio, sealing effectiveness is poor.This method can only satisfy the requirement of simple waterproof of short time, and after long-time the immersion, 703 glue cause water-tight to lose efficacy easily from the measured object surface isolation in the stronger seawater of corrosivity.
Summary of the invention
The applicant exists the shortcoming that can not well effectively seal foil gauge in the test experiments under water at above-mentioned having now, a kind of strain gauge water-proof sealing method and structure thereof are provided, thereby can carry out the sealing of foil gauge fast and effectively, shorten the running time greatly, improve sealing effectiveness.
The technical solution adopted in the present invention is as follows:
A kind of strain gauge water-proof sealing method comprises following steps:
The first step: the tested body structure surface of polishing;
Second step: adopt clean-out system to clean the polishing surface;
The 3rd step: foil gauge is firmly sticked on tested body structure surface after the polished and cleaned with instant drying adhesive water;
The 4th step: the connection terminal that will measure lead and foil gauge firmly welds;
The 5th step: SB type waterproof gasket cement evenly is covered in the foil gauge surface fully;
The 6th step: be covered in SB type waterproof gasket cement surface fully with aluminum foil and adhesive tape;
The 7th step: at sealing area and and coating oil enamelled coating on every side.
Prepared according to the method described above strain gauge water-proof sealing structure, be pasted with foil gauge by the test point surface of geodesic structure, measure wire bonds on the connection terminal of foil gauge, be coated with SB type waterproof gasket cement, aluminum foil and adhesive tape and waterproof paint on foil gauge top successively, cover foil gauge and neighboring area thereof fully.
Adopt the hermetically-sealed construction of strain gauge water-proof sealing method of the present invention not only can shorten the seal operation time of foil gauge greatly, running time for single test point is no more than 5 minutes, and because waterproof paint, aluminium foil and SB type waterproof gasket cement multi-sealed, can guarantee long waterproof sealing effect, in the briny environment of highly corrosive, at least effectively water-tight is more than half a year.Waterproof sealing structure of the present invention can guarantee that insulation resistance reaches more than the 100M Ω, also can be used for the waterproof sealing of other electronic devices and components or sensor simultaneously.

Embodiment
Strain gauge water-proof sealing method of the present invention comprises following concrete steps:
The first step: carried out detail sanding by geodesic structure 1 surperficial zone to be tested, grinding off the oxide film on surface, and carry out polishing, making the surface smooth substantially;
Second step: to repeatedly being cleaned, remove degreasing and dust by geodesic structure 1 surface finish polishing area with acetone or other clean-out systems;
The 3rd step: with instant drying adhesive water with foil gauge 2 firmly stick on after the polished and cleaned by geodesic structure 1 surface;
The 4th step: the connection terminal that will measure lead 6 and foil gauge 2 firmly welds;
The 5th step: SB type waterproof gasket cement 3 is sticked on foil gauge 2 surfaces, and separate paper is pressed pressure with pointing pad on, evenly covers foil gauge 2 and connection terminal and partly measures around the lead 6 up to SB type waterproof gasket cement 3; The manufacturer of SB type waterproof gasket cement is a Japanese republicanism company, is the commercially available prod, and its form is for having plastic paste, can not trickle and set time rapid, have cohesive preferably with the metal surface;
The 6th step: with an aluminum foil and adhesive tape 4 that is a bit larger tham SB glue zone stick on above the SB glue and around, assurance covers aluminum foil and adhesive tape inside fully with SB glue zone;
The 7th step: with sealing area and and apply 1～2 layer of anti-seawater paint 5 on every side, guaranteeing can rust corrosion in seawater by geodesic structure 1.
According to above-mentioned strain gauge water-proof sealing method, strain gauge water-proof sealing structure of the present invention as shown in Figure 1 and Figure 2, be pasted with foil gauge 2 by the test point surface of geodesic structure 1, measuring lead 6 is welded on the connection terminal of foil gauge 2, be coated with SB type waterproof gasket cement 3, aluminum foil and adhesive tape 4 and anti-seawater paint 5 on foil gauge 2 tops successively, cover foil gauge 2 and neighboring area thereof fully.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
