Abstract
The utility model provides a tester for the surface tension of liquid materials, which comprises a light source, a high-temperature furnace, a vacuum pump and a camera. The utility model is characterized in that the light source is a laser light source, and a dedicated light filter is arranged between the recorded object and the camera. The camera which is used as a high-definition digital camera is connected with a computer. The utility model has the beneficial technical effects that the parallelism of the light source is ensured, the interference of ambient light is efficiently eliminated and the measuring continuity and the accuracy of analyzed results are ensured.
Description
Technical field
The utility model relates to a kind of testing apparatus, especially relates to a kind of liquid material surface tension apparatus.
Background technology
Existing liquid material surface tension apparatus owing to adopt sheet natural light or incandescent lamp bulb as light source, can't be avoided the interference of non-parallel light source such as surround lighting to the determination data reliability, and it is not high that it measures precision; Simultaneously, existing liquid material surface tension apparatus adopts traditional camera record specimen shape, the film limited amount owing to once pack in traditional camera inside, at short notice high frequency, finish the shooting of up to a hundred photos continuously, therefore the capillary continuous change procedure of liquid material can not be truly, at length write down, thereby analysis and research can't be finished the material surface tension change law.
Summary of the invention
The utility model provides a kind of can eliminate ambient light interference, the capillary analyzer of continuous coverage liquid material, its technical solution is: a kind of liquid material surface tension apparatus, comprise light source, high temperature furnace, vacuum pump and camera, it is characterized in that: described light source is a LASER Light Source, and is provided with dedicated optical filter between object that is recorded and camera.Described camera is the HD digital camera, and is connected with computing machine.
Useful technique effect of the present utility model is: adopt laser to guarantee the collimation of light source as light source; Adopt dedicated optical filter to eliminate the interference of surround lighting effectively; Adopt the HD digital camera to guarantee continuity of measurement and precision of analysis.
Description of drawings
Accompanying drawing is a structural drawing of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of liquid material surface tension apparatus comprises light source 1, high temperature furnace 2, vacuum pump 3 and camera 5, it is characterized in that: described light source 1 is LASER Light Source, and is provided with dedicated optical filter 4 between object that is recorded and camera 5.Described camera 5 is the HD digital camera, and is connected with computing machine 6.
Use laser as light source 1, guaranteed the collimation of light source 1; Between object that is write down and camera 5, dedicated optical filter 4 is set, filters other light source except that laser, eliminated the interference of surround lighting; Adopt the HD digital camera, improve image quality, guaranteed continuity of measurement and precision of analysis.
The profile that drips the shape melted material in the high temperature furnace 2 is taken record by camera 5, and is directly inputted to computing machine 6, with the Flame Image Process and the calculation procedure that have write, calculates the surface tension of liquid material.
