A research team at Pennsylvania State University has developed a new type of liquid paint, which can save at least 50% water by spraying it on ordinary ceramic toilets According to research in the British journal Nature sustainable development, the coating needs to be sprayed in two steps The first step is to spray a molecular modified polymer on the inner wall of the toilet for "bottoming", and the dried polymer will grow molecules like hair, but the diameter is only about 1 million of the human hair; then use the second coating to inject a layer of lubricating film into the surface of these "hair" to form a very "slippery" and waterproof surface Research shows that after two-step spraying, when only a small amount of water is used to wash the artificial excrement, the latter will slide down completely, without any adhesion, and the toilet's antibacterial and deodorizing functions will be enhanced The researchers said it took less than five minutes for the entire spray process, and the second coating needed to be reapplied after 500 flushes This method can save 90% water in laboratory test and at least 50% water when used in the traditional toilet without modification.
