Problems solved by technology

[0003] At present, the products of foreign multi-color irreversible temperature-indicating coatings are mainly represented by the multi-color-changing irreversible temperature-indicating coatings produced by Rolls-Royce.
There are currently 8 varieties of SW-M multi-color irreversible temperature-indicating paint series in China, but there are disadvantages such as large temperature error, long response time, and unobvious color difference.
Moreover, most of the existing domestic multi-color irreversible temperature-indicating coatings were developed from the late 1970s to the early 1980s. Due to changes in raw materials, the quality of the products was unstable, and some products could no longer be produced. Compared with foreign countries, the domestic multi-color There is a big gap in the performance of irreversible temperature display coatings
