Problems solved by technology
Existing testing equipment for the Vicat softening temperature of plastic pipes usually includes a heating box and a test frame. The heating box is usually filled with heat-conducting oil, and a heating device is installed to heat the heat-conducting oil, and then the heat-conducting oil heats the plastic pipe. , but due to the large volume inside the box, the temperature of the heat transfer oil at different positions in the box is not uniform, and the accurate oil temperature for heating the plastic pipe cannot be obtained, thus affecting the accuracy of the test

The invention discloses plastic tube Vicat softening temperature test equipment. The plastic tube Vicat softening temperature test equipment comprises a heating box containing heat conduction oil andfurther comprises a test frame and a control device which are mounted on the heating box. A heating device and a stirring device are arranged in the heating box. Mounting holes are formed in the top of the heating box. The test frame comprises mounting plates erected on the mounting holes. Through holes enabling the ends of plastic tubes to penetrate through and extend into the heating box are formed in the mounting plates. The hole diameter of the through holes is matched with the tube diameter of the plastic tubes. Supporting plates used for supporting the bottom ends of the plastic tubes are fixedly connected to the positions below the mounting plates, extend into the heating box through the mounting holes, and are provided with positioning grooves matched with the bottom ends of the plastic tubes. Dial indicators are arranged above the mounting plates. Pressure measurement heads of the dial indicators can abut against the top ends of the plastic tubes. The plastic tube Vicat softening temperature test equipment can effectively improve the accuracy of a plastic tube Vicat softening temperature test.
Description
technical field [0001] The invention relates to the field of building material testing devices, in particular to Vicat softening temperature testing equipment for plastic pipes. Background technique [0002] With the development of cities and the construction of roads, in recent years, compared with traditional metal pipes, plastic pipes have the advantages of light weight, corrosion resistance, high compressive strength, good insulation, safety and sanitation, small water flow resistance, long service life, and easy installation. Convenience and other features have been favored by the pipeline engineering industry and occupy a very important position, forming an unstoppable development trend. At the same time, due to the disadvantages of poor heat resistance and easy aging of plastics, its application on a deeper and wider level is limited. The heat resistance of a plastic usually refers to its ability to maintain its physical and mechanical properties when the temperature...
