Description: Nail mechanical galvanizing is a kind of electric galvanized, hot galvanized iron, dacromet process different anticorrosion coating, its technological characteristics is: room temperature operation, form does not belong to Nail Making Machine manufacturers the electrochemical deposition, is a component of rotating barrel plating, load cylinder
The media parts of collisions, accounting screw machinery industry can transfer to form the coating; Coating structure for the level of spherical zinc powder particles to the mechanical force transfer collision deformation, become flat, saucer-shaped zinc to condensation of the grain layer overlay for coating, this
Structure of coating with metal zinc basic physical characteristics, the function of the coating effect is to provide basic parts of iron rust protection requirements of the anodic protection coating. Process characteristics are: high strength steel industrial parts do not produce hydrogen embrittlement of harm and small barrel plating parts
Heavy-duty coating instead of hot dip galvanizing technology has the competitive advantage of industrial applications.
1. Before the parts processing, oil removal, rust removal
Of common parts, according to surface treatment of the conventional method, but the high strength steel substrate for parts of rust removal, in addition to scale, especially pay attention to, because we can not longer using strongly acidic chemical materials containing hydrogen ions on parts surface rust removal and deoxidization skin, this place
Ignore certain hydrogen permeability influence on steel base parts, therefore, should use nail mechanical method to solve, such as sand blasting, vibration finishing and shot blasting process, etc.
2. The flash replacement copper plating
Replacement copper layer thickness requirements, but to completely cover parts surface of substrate, its role is: improve the bonding strength, is conducive to the uniformity of coating surface condition, stop the process wire nail machine manufacturers to produce hydrogen infiltration of matrix. Another role found, because the copper Same layer has good conductivity, the thickness of zinc plating galvanized nail machinery parts with zinc impregnation parts salt fog box comparing experiment examination, reach 11 cycles in salt spray test, found that due to the salt fog water flushing, edges and corners of the batch of zinc impregnation parts
Quantity appear red rust, and mechanical galvanized nail edges while is dew matrix, but the batch six pieces of all does not produce red rust: this is due to the small displacement copper layer resistance, electronic conductive, ensures normal electrochemical cathode is the iron substrate, so the Replacement of nail mechanical zinc plating copper layer structure of electrochemical anti-corrosion ability is especially important.
3. Mechanical galvanized nail sedimentary transition layer
The process is for replacement of copper layer, implementation step is quantitative mechanical galvanized nail special initiator and a small amount of crossing the zinc powder to join within the cross tube rolling, rolling 3-5 min can be formed to make the original parts in silver copper layer into the basic compound.
The galvanized layer. The merits of the quality of the galvanized layer will affect the subsequent upset cross the toughness and cross layer binding force.
4. The nail machine galvanized deposits
Quantitative in batches to join heavy zinc initiator, cross the layer Nail machine manufacturer thickness requirements rhyme zinc powder is available in 15 cm, 30 min set into the process, to fulfill the requirements of industrial components anticorrosive galvanized layer thickness.
5. Water polishing
Mechanical galvanized nail surface of powder in the mirror bright cross layer, water polishing process is mechanical galvanized nail initiator and zinc powder. Barrel plating continue to roll, make parts to achieve uniform brightness of the surface of the silver plating surface, generally need to turn the 5-10 in,
Although the coating to reach has a bright luster, but the surface is smooth and brightness is superior to hot dip galvanized layer. Water polishing plating barrel rotation time has a great value, exceeds the maximum of the particular zinc coating will have a certain degree of cutting.
6. Parts surface chromium passivation
Nail mechanical galvanizing layer, especially in the initial conditions, in the humid air, easy in a white corrosion coating on the surface of the object, must through the transparent chromium passivation, chrome yellow blunt, make the form chromium passivation film to prevent corrosion, produce white. 7. Acceptance testing
Nail galvanized thickness and coating quality of mechanical industry, depends on the process operation, process formulation and process of qualitative and quantitative specification control: so the coating quality of testing that is particularly important, qualified inspection results to nail ZhiDaoZhi mechanical galvanizing technology on no With the correct parts batch quantity production.
