Dihydrogen phosphate, zinc phosphate solution is divided into four characteristics and advantages, they each have their own. Zinc nitrate, zinc phosphate dihydrogen phosphate cryogenic liquid applied to the surface treated steel products. Phosphate coating in a short time form a dense, rust resistance of phosphate coatings, and can significantly improve the adhesion substrate and coating. The biggest advantage is that the bath is extremely stable, zinc nitrate, phosphate short time, low processing temperature, zinc nitrate wholesale, without any heating equipment, uniform fine phosphate coating, wide operating range of technology, little sediment, are environmentally friendly dihydrogen phosphate, zinc phosphate solution type. Compared with the paint film, powder coating has many advantages, such as environmental pollution, film hard, good toughness, and the substrate with strong corrosion resistance higher. However, higher pre-treatment requirements, so the requirements for dusting workpiece requirements mentioned pre-treatment process and dusting systems, thus giving binding conditions for the use of powder. In order to be able to strengthen the metal surface converted into a solid powder adhesion and improved surface protective, whether steel or zinc, aluminum and its alloys before processing is necessary. In order to enhance the binding force of the powder and the substrate film, improve the protection, treatment may be different depending on the type of metal. The price of zinc nitrate, zinc nitrate, three-level three-level chemical industry provided by the Jinan Chemical Co. Jinan three ping Chemical Co. (www.sanpinghuagong.com) strong, credible, in Jinan, Shandong chemical products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead three levels of chemical into the brilliant and you work for a better future!
