(Packaging technology, package materials, underwriting products) At a construction company, a salesman from my office took out a bag of green powder, added water to mix and brush on the wall, and spent 4 hours on a wet silk cloth for 30 times without powder shedding; 450 hours of boiling water (corresponding to 5000 hours of cold water immersion) The walls are still green; soaked in boiling lye 4 . . Hours, the green will not fade; cool down to 1% °C and then warm up to 10. °C, the green color remains unchanged. As a result, a contract for 500,000 yuan was signed on the spot. According to the appraisal of the Chinese Academy of Sciences, this coating is not only a domestic initiative, but also has reached the same level in the 1980s.
