Advantages of Dacromet process and composition of Dacromet machinery and equipment
Dacromet is a new surface treatment technology, compared with traditional electroplating. What are the advantages of its manufacture? What are the components of Dacromet machinery and equipment? Want to master this problem? Then follow me to understand.
Advantages of Dacromet process
1. Strong corrosion resistance: the thickness of Dacromet process film is only 4-8 μ m. But the actual effect of antirust treatment is 7-10 times higher than that of traditional phosphating treatment, hot dip galvanizing or architectural coating. The standard parts and pipe joints solved by Dacromet process have no red rust after salt spray test for 1200h.
2. Hydrogen free ductility: Dacromet process determines that Dacromet has no alkali embrittlement, so Dacromet treatment is especially suitable for the coating of stress parts.
Composition of Dacromet machinery and equipment
The key parts of Dacromet machine and equipment are dip coating system software, suction filtration and dehydration system software, coating liquid circulation system mixing system software, coating liquid temperature adjustment system software (controlled by chiller), coating liquid purchasing equipment, product workpiece transportation system software (composed of electric hoist and double rail Longmen Bridge), pneumatic automatic control system, electrical equipment automatic control system, etc. 1. Temperature control dip coating tank: it is composed of inner cylinder, outer cylinder and heat insulation layer. A temperature regulating water jacket is set in the middle of immersion inner cylinder and heat insulation cylinder, and heat insulation material is added between heat insulation cylinder and outer cylinder to ensure that the temperature control of coating liquid in inner cylinder is within 20 ℃ ± 3℃。 The immersion tank is made of stainless steel plate. 2. Centrifugal drying mechanism: according to the high-speed operation of the centrifugal dehydrator, remove unnecessary coating liquid from the product workpiece, control the thickness of the coating to make the coating even and level. The centrifugal dehydrator has positive, overturning, unilateral and dual functions. The speed ratio of suction filtration, frequency of positive and negative sides of suction filtration and suction filtration time can be adjusted. In the design and manufacture, six speed ratios of 175r / min, 200R / min, 225r / min, 250r / min, 275r / min and 300r / min are set in the PLC program flow device in advance. The switch is used to operate the change on the stock disk of the control box, and the other gear is manual stepless speed change. In this way, the application of the design scheme is very convenient, stable and the actual operation time is short.
