Dacromet, a new metal surface preservation material. This new metal preservative treatment technology was widely used abroad in the 1980s as an alternative to electroplating and thermal impregnation of zinc. It is highly characterized by non-pollution and superior preservative properties. The core technology of the project is the preparation of ultra-subsidized zinc aluminium powder, which was developed by our company in dacro with an innovative process to produce tablet zinc aluminium powder with a powder size of 10 x 10 x 0. 1um, reaching an internationally advanced level. The whole process is safe, non-polluted, non-noise, low-cost and can be used as an alternative to importing the same product, while significantly improving the corrosive properties of coating materials, with extensive applications for metal preservation in areas such as automobiles, machinery, electricity, bridges and marine engineering. Our company's method of manufacturing dacro has been patented (02144967. 8)...
