Posted on 2015-10-26 Dacromet technology originated in the seventies of the 20th century, the United States, China in the 1980s introduced Dacromet technology, and through the digestion and absorption, and gradually realize the process equipment and, Dacromet fluid of localization. In 2002, the State Administration of quality supervision, inspection and Quarantine issued the national standard "GB/T18684-2002 zinc chromium coating technology conditions".
Dacromet technology has attracted more and more attention of researchers and enterprises related to its superior characteristics.Dacromet coating characteristics:
1, friendly environmentDacromet the way closed cycle, in Dacromet coating and curing process of evaporation of water vapor and a small amount of organic matter are within the scope prescribed by the state, there is no traditional electroplating process in the production of large quantities of pollutants and waste water. Therefore, Dacromet in some way up that may be referred to as a "green" technology.
2, high corrosion resistanceDacromet coating antirust effect is 7-10 times higher than that of traditional electro galvanized, hot-dip galvanized or paint coating method and standard of Dacromet coating in resistance to salt fog test more than 1200 hours after has not yet appeared red rust, visible strong corrosion.
3, high heat resistanceCompared with the traditional galvanized layer of passivation film in higher than 70 DEG C is dehydrated cracking phenomenon, Dacromet coating in high temperature of 500 DEG C can still maintain stable performance, corrosion resistance is excellent.
4, no hydrogen embrittlementDacromet coating without the acid pickling and curing at high temperatures, from the process determines the no hydrogen embrittlement phenomenon, suitable for high strength parts and a spring member.
5, high permeability,adhesionDacromet by means of dipping treatment, is not restricted by the shape of a workpiece; the good adhesion is reflected not only in the matrix, and other additional coating also has a strong adhesion.
Changzhou Junhe Technology Stock Co.,Ltd. is a commitment to manufacturing with fine chemicals, special equipment and service system resolve scheme provides the private high-tech enterprises. Committed to Dacromet and Dacromet technology research, has own Dacromet coating production lines and advanced Dacromet equipment, Dacromet coating equipment, Dacromet coating machine and quality of Dacromet coating liquid.
