A test strip is a material used to measure the concentration of a chemical or some characteristic of a liquid. Test strips are most often used to test a liquid's pH level, but some types of test strips serve other purposes, such as detecting the presence of a contaminant. A test strip is usually a piece of a paper that contains an indicator.
A clamp and testing device for waterborne paint peel performance testing
This application discloses a fixture and testing device for testing the peel performance of waterproof coatings, relating to the field of test fixture technology. It includes a base and a clamping assembly. The base includes a bottom plate and side plates located on both sides of the bottom plate, forming a mounting cavity. Multiple roller sets for movable test samples are arranged within the mounting cavity. The clamping assembly is located above the roller sets and includes a driving component and two clamping components symmetrically arranged within the mounting cavity. The driving component can drive at least one clamping component to move towards or away from the other clamping component. This application utilizes multiple roller sets to move large-sized substrates of the test samples, solving the problem of inconvenient movement of large-sized substrates. Simultaneously, the clamping assembly located above the roller sets clamps the large-sized substrates of the test samples, facilitating peel testing of test strips on the large-sized substrates, thus improving the convenience of peel testing on large-sized test substrates.
