Abstract

The present invention relates to a PVC pipe aging detecting device. The detecting device is characterized by comprising a detecting unit, a clamping assembly, a hydrogen chloride collecting cover, a vacuum pump, a current detecting component, a water tank and an amplifying circuit. One end of the vacuum pump is connected with the current detecting component by using a leather hose, and the other end of the vacuum pump is connected with the hydrogen chloride collecting cover by using the leather hose; the clamping component is arranged under the hydrogen chloride collecting cover; and the current detecting component is connected with the detecting unit through the amplifying circuit. According to the technical scheme of the present invention, the overall design is compact and ingenious, theaging degree of the PVC pipe can be quickly and accurately determined, and the work efficiency can be improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a PVC pipe aging detection device, and belongs to the technical field of structural components of the detection device. Background technique [0002] Since the industrialization of polyvinyl chloride (PVC) in the 1930s, it has been widely used in the production of various pipes, plates, wire sheaths, doors and windows, etc. due to its relatively low price, good physical and chemical properties. Therefore, in the past few decades of development, PVC has become one of the irreplaceable materials in national life. [0003] Although the structure of PVC itself is relatively stable, due to the unavoidable side reactions with other materials or the introduction of polar groups (the remaining part of organic matter after losing an atom or an atomic group) during production, the chain structure of PVC occurs. Change. If the PVC material is in some special environments such as high temperature and ...
