The feature applied in example can be combined with each other.It is also understood that term used in the embodiment of the present invention is specific in order to describe
Specific embodiment, rather than limiting the scope of protection of the present invention.The test of actual conditions is not specified in the following example
Method, usually according to normal condition, or according to condition proposed by each manufacturer.
When embodiment provides numberical range, it should be appreciated that except non-present invention is otherwise noted, two ends of each numberical range
Any one numerical value can be selected between point and two endpoints.Unless otherwise defined, the present invention used in all technologies and
The grasp and record of the invention of scientific term and those skilled in the art to the prior art, can also use and this hair
Any method, equipment and the material of the similar or equivalent prior art of bright method as described in the examples, equipment, material is realized
The present invention.
When detecting the condom prepared with some new materials using traditional detection method, due to the property of material itself
The presence of needle outlet can not be usually effectively detected in matter, and by taking polyurethane material as an example, polyurethane material is a kind of dielectric material,
Its dielectric constant is very low.There are glass transition temperatures for polyurethane material, when temperature is lower than glass transition temperature, polyurethane
In glassy state, sub-chain motion is frozen, and the polar group orientation on structural unit is restrained by segment, and alignment capability is low, dielectric
Constant is small, poor insulativity, and when temperature is higher than glass transition temperature, polyurethane is in elastomeric state, and segment mobility is big, pole
Property group orientation by segment restrain it is smaller, dielectric constant be greater than glassy state, good insulating is in elastomeric state.To polyurethane condom into
Row heating, can improve its dielectric constant, increase the insulating properties of polyurethane condom, and pin hole is examined when improving polyurethane condom electric-examination
Extracting rate.
As shown in Figure 1, the present invention provides a kind of detection method of condom, the detection method includes at least following step
