Normal temperature iron phosphating liquid is a transparent, green liquid that dissolves easily in water. As a sand solution, it cleans and at the same time phosphates iron surfaces quickly and effectively and prepares them perfectly for painting.
Currently, the pretreatment commonly used in the market is sand blasting technology and phosphating liquid mainly suitable for steel. The phosphating liquid includes tank preparation liquid and replenishing liquid. The pre-treatment stage of the sandblasting process refers to the treatment that should be carried out on the surface of the workpiece before it is sprayed and sprayed with a protective layer. The quality of pre-treatment in the sandblasting process affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating. If the pre-treatment is not done well, the rust will continue to spread under the coating, causing the coating to be damaged. The layers fall off in sheets. For phosphating treatment on the surface of steel, the traditionally used phosphating liquid has high temperature, high energy consumption, long processing time, and high cost. Especially for large workpieces such as machine tools, automobile chassis and parts, if high-temperature phosphating is used , it is indeed difficult for some small and medium-sized enterprises. However, even if room-temperature phosphating liquids are used, most of them require a certain temperature and have slow fusion speed and harsh operating environment. During use, toxic gases or sediments will be produced, affecting environmental quality. In recent years, there have been reports on the market for room-temperature phosphating solutions. However, during use, the treatment time is too long, and the acidic substances corrode the steel surface greatly. If it is not serious, it will affect the quality of phosphating. Our normal temperature iron phosphating liquid has a simple composition, no toxic and harmful gases, and strong production suitability, making it more suitable for operations in cold weather in the north.
