Abstract

The invention provides an atomization testing device. The atomization testing device comprises an atomizing cup which is an open-mouthed cylinder container, wherein the bottom of the atomizing cup isused for placing a to-be-measured sample; a sample compacting ring placed at the bottom of the atomizing cup and used for fixing the to-be-measured sample; a first filter screen arranged on the samplecompacting ring and contacted and separated with the sample compacting ring; a second filter screen arranged over the first filter screen and keeping a certain distance with the first filter screen;and an aluminium foil arranged at a port of the atomizing cup and used for covering the port of the atomizing cup, wherein the surface of the aluminium foil faces to the bottom of the atomizing cup; wherein a mesh size of the first filter screen is greater than the mesh size of the second filter screen. The atomization testing device can be used for increasing the accuracy of the atomization testresults.

Description

technical field [0001] The present application relates to the technical field of automobile testing, in particular to an atomization testing device and method. Background technique [0002] Many polymer materials are used in automotive interior parts, and polymer materials are easily degraded into small molecules when heated, and form fog in the car window. This process is called atomization. Atomization will reduce the visibility of the window glass, and at the same time, substances harmful to the human body will be produced during the atomization process. Therefore, in the inspection of automobiles, it is necessary to conduct atomization tests on polymer materials in interior parts. [0003] When performing atomization tests on some lightweight foam fabric samples, the lightweight samples tend to float due to the convection of hot and cold air during the heating process. In addition, during the heating process, the lightweight foam fabric will produce flocs that can fl...
