Description
Technical field
The present invention relates to a kind of manufacture method of atmospheric corrosion monitoring sensor, the atmospheric corrosion monitoring for belonging to material is led
Domain.
Background technology
The corrosion of material in an atmosphere is the important way of material damage, and the atmospheric corrosion of observation and research material is material
Research and the important topic of application.It is conventional method by that can cut down Buddhist nun's battery-type sensors to detect material atmospheric corrosion.It
General principle be by detect two kinds of different metal materials under thin liquid film state because material potential difference and caused by it is micro-
Electric current and the corrosion for detecting material.
In order to obtain measurable electric current, the general manufacture method that can cut down Buddhist nun's battery sensor is by the more of two kinds of materials
Piece thin plate is interlaced to be arranged under the overlay, and is separated among thin plate with very thin insulating materials, forms an assembly, and again by assembly
Facade（Directly in sheet plane）It is polished flat and exposes two kinds of metallic matrixes, forms the sensitive surface of sensor.When have dewfall,
Rain, snow etc. will produce an observable corrosion between two kinds of metal materials when producing thin liquid film in sensitive surface because of corrosion
Electric current.This method manufacture can cut down Buddhist nun's battery sensor because to obtain as far as possible sensitive detectable electric current, it is necessary to ensure two kinds
The spacing of sheet metal is as far as possible small, mutually insulated；Want multi-disc metal to be mutually staggered simultaneously, manufacture and acquire a certain degree of difficulty.
Have the gap of certain depth because sheet metal is closely spaced, between piece, insulating cement penetrate into it is difficult, in sensor use often because
Liquid in sensitive surface penetrate between sheet metal cause thin slice occur self-corrosion and caused by the change of sensor construction and broken
Bad, sensor corrosion current value changes very greatly, often up to 10% with the extension of usage time；The service life of sensor（With electric current
Change 20% is failure foundation）Only 1-2, at least half a year.
The content of the invention
It is an object of the invention to provide a kind of simplicity can reliably cut down Buddhist nun's battery sensor manufacture method, ensure manufacturing process
In convenience and controllable, reduce during use and sensor self-corrosion breakoff phenomenon occur.
A kind of manufacture method of atmospheric corrosion monitoring sensor, comprises the following steps：By two different kinds of wire
Or line is wound around on the cylinder of surface insulation side by side, two kinds of mutually insulateds between wire or line, every kind of wire or
The outer surface of line individually makes electrical contact with atmospheric environment, and two kinds of wires or line are drawn into formation respectively with wire can cut down Buddhist nun's battery biography
Sensor.
In the wire or line of two kinds of different materials, at least one is the wire or line that surface carries insulated paint；Two kinds
The wire of different materials or the diameter of line are identical or essentially identical.The material of wire or line can from metals such as iron, copper, aluminium or
Selected in alloy.
After two different kinds of wire or line wound side by side is scribbled on surface on the cylinder of uncured insulating cement,
Wire or line outer surface re-coating insulating cement after winding, it is by being ground that metal surface is exposed after adhesive curing.
Described cylinder is lucite or plastic cylinder；It may also be metallic conductor of the surface through insulation processing, institute
It is curable resin or glue to state insulating cement, such as epoxy resin.
The specific manufacturing process of the present invention：The cylinder of surface insulation is selected, its surface is applied into one layer of insulating cement；Select simultaneously
Two kinds of diameters essentially identical wire or line are selected, wherein at least one is the insulated conductor that surface carries insulated paint；By two kinds
Wire or line individual layer are closely wound in periphery side by side；Wire or line outer surface after winding applies one layer of insulation
Glue, the space between tinsel is full of；After adhesive curing of insulating, it is ground since insulating cement outer surface, exposes two kinds of gold
Belong to matrix, now insulated between two kinds of metals and have certain spacing, two kinds of wires or line are drawn into formation respectively with wire can
Cut down Buddhist nun's battery sensor.
The advantages of the inventive method：Material is easy to get in manufacturing process, by controlling magnet wire insulation thickness degree, grinding depth
Two kinds of intermetallic spacing distances are easily controlled etc. factor, method is workable；It is deep due to insulating cement need not be penetrated into
Metal slit in, sensor metal be not present because corrode in metal slit and caused by damage, the reliability of sensor and resistance to
Long property greatly improves.
Below by the drawings and specific embodiments, the present invention will be further described, but is not meant to protect the present invention
Protect the limitation of scope.
Brief description of the drawings
