Embodiment
The utility model is that THERMAL IMAGING NONDESTRUCTIVE TESTING technology is used in Disposable paper cup quality testing, thermal infrared imager 5 is to survey infrared energy (heat) by noncontact, and be converted into electric signal, and then on display Heat of Formation image and temperature value, and a kind of checkout equipment that can calculate temperature value.Infrared energy is the invisible energy of a kind of naked eyes, and its wavelength is very long, cannot be detected by naked eyes.It is the part in electromagnetic wave spectrum, and the mankind are perceived as heat by it.Different from visible ray, in infrared field, the object of every temperature more than absolute zero can both distribute heat.Even the very cold object in surface, can launch infrared energy equally as ice cube.The temperature of object is higher, and the infrared energy of its institute's radiation is just stronger.Thermal infrared imager 5 can help us to see the situation that naked eyes cannot be seen.When there is defect in interior of articles, it will change the heat conduction of object, body surface Temperature Distribution is changed, thermal infrared imager 5 can be Temperature Distribution thermal map by the body surface heat precise quantification detecting, and from thermograph, can accurately identify the abnormal conditions that may exist with object analysis.Due to technology innovation in recent years, the hardware performance of thermal infrared imager improves constantly, and environmental suitability is stronger, with better function, operation use is more convenient, can meet the user demand of different user under different occasions.Due to picked-up be that the infrared energy of body surface need not contact testee, can not disturb tested temperature field, therefore Infrared Thermography Technology is very suitable for measuring the object of motion, dangerous object (as high voltage cable) and unapproachable object yet.
Infra-red thermal imaging instrument 5 basic functional principle, according to Planck law, wavelength is certain, measure infrared energy E and just can calculate temperature value T, temperature is different with radiance, can form the different distributions of infrared radiation, instrument processor can calculate the temperature value of each measuring point reality in detail, and demonstrates and the corresponding two-dimentional colored thermography of body surface heat distribution with the temperature scale of different colours.Use this method, just can realize target is carried out to remote hot state imaging and thermometric, and the state of testee is analyzed to judgement.
If make to form in target to be measured hot-fluid communication process, because defect part in target is with there is no the pyroconductivity of defect part different, theoretical according to heat-conduction equation, this species diversity will cause in target defective part and there is no each self-corresponding surface temperature of defect part different, that is corresponding infrared intensity is different.If the thermograph of object every bit is got off, form field pattern picture, just can obviously find out the rejected region that it is inner.The every bit of the infrared image of thermal infrared imager picked-up is corresponding certain temperature all, and can according to the depth of color, judge the height of temperature, and same color represents that temperature is identical.
It is uniform that hot-fluid injects; to flawless object; it is uniform substantially that the temperature field of front and back distributes; if interior of articles exists defect, in fault location Temperature Distribution, will change, for the defect of thermal insulation; positive detection mode; fault location is " focus " because of heat build-up, and when the back side is detected, fault location is low warm spot; And for the defect of thermal conductivity, during positive detection, the temperature of fault location is low warm spot, the temperature that the back side detects fault location is " focus ".Visible, adopt infrared detection technology, can detect visually material surface and superficial defects and scope.
