Embodiment Construction

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely intended to illustrate the invention and are not intended to limit the invention.

[0038] It should be noted that when the element is referred to as "fixed to" or "set to" another element, it can be directly on the other element or indirectly on the other element. When one element is called "connected to" another element, it can be directly connected to another element or indirectly connected to the other element.

[0039] It is to be understood that the term "length", "width", "upper", "lower", "front", "post", "right", "vertical", "level", "top" The orientation or position relationship of "bottom" "inside", "outside", etc. is based on the orientation...

Abstract

The invention provides a test method and a test board for the compatibility of a chemical medium and plastic, and the test method comprises the steps of test board preparation, bottom thrust test and top burst test. Whether the chemical medium to be tested and the plastic to be tested are compatible or not is judged by comparing the roll degrees of the screw columns in the bottom thrust benchmark test and the bottom thrust compatibility test, and then the screw columns are subjected to top burst benchmark test and top burst compatibility test. Whether the chemical medium to be tested and the plastic to be tested are compatible or not is judged by comparing the deformation degrees of the screw columns in the top bursting benchmark test and the top bursting thrust compatibility test, so that the comparison and screening of the plastic material on the contacted chemical medium material are achieved, and the preferable use is achieved.

Description

Technical field [0001] The present invention belongs to the field of chemical media and plastic compatibility detection, and more specifically, the test method involving a chemical medium and plastic compatibility and a test plate. Background technique [0002] Screw columns, also known as BOSS columns, is a common structure in plastic products, as well as one of the most problems in the application of plastic products. When the screw post is processed by rust-proof, decontamination, lubrication, the screw is exposed to acid and oil. If the chemical medium is used to be in contam with the plastic material, or the plastic material itself does not resist this chemical medium, the surface Chemical media long-term contact screws can cause environmental stress cracking. The screw column roots and tops are prone to stress concentration due to the presence of a sharp corner, and the two parts are also the most susceptible to the environmental and chemical media to cause breaks or cracks...
