The replacement of hot-dip galvanizing process with anti-corrosion plating of nail making machines has a competitive advantage in industrial applications.
1. Parts pretreatment, degreasing, rust removal
For ordinary parts, it can be treated according to the conventional method of surface treatment, but the descaling and de-oxidizing scale of high-strength steel matrix parts, especially attention should be paid to, because the surface of the parts cannot be descaled and deoxidized for a long time by using strong acidic chemical materials containing hydrogen ions, so Iron Nail Making Machine that the treatment will have a certain hydrogen leakage effect on the steel base of the parts, so it should be solved by nail making machinery: such as sand blasting, vibration light decoration, shot blasting process, etc.
2. Flash plating replacement copper
There is no thickness requirement for the replacement copper layer, but it must completely cover the surface of the part substrate, and its role is: to improve the adhesion of the coating, to facilitate the uniformity of the surface condition of the coating, and to block the infiltration of hydrogen into the matrix generated by the process. Another role found that because the copper layer has good electrical conductivity, the same zinc plating thickness of the nail-making mechanical galvanized parts and galvanizing parts are in the salt spray box for test assessment and comparison, when the salt spray test reaches 11 cycles, it is found that due to the erosion of the salt wire nail making machine spray water flow, the batch of parts in the corners of the zinc-infiltration parts appears red rust, and although the nail-making machinery galvanizing edges have seen the exposed matrix, but the batch of six pieces do not produce red rust: this is due to the small resistance of the replacement copper layer, the electronic conductivity is smooth, ensuring the normal electrochemical cathode state of the iron matrix, so, This replacement copper layer is particularly important for the electrochemical corrosion resistance of the galvanized coating structure of the nail making machinery.
3. Nail making mechanical galvanizing deposition transition bottom layer
This process is for the replacement of the copper layer, the implementation step is a quantitative nail-making mechanical galvanizing special initiator and a small amount of galvanizing powder added to the rolling cylinder, rolling 3-5 minutes can form the original parts of the basic copper layer into a silver-gray composite galvanizing layer. The quality of the galvanized layer will affect the toughness and adhesion of the subsequent thickened ferrous layer.
4. Mechanical galvanizing deposition of nails
Quantitative batch addition of sinking zinc initiator, the thickness of the layer requires that the zinc powder can be determined in 15cm-30min to achieve the thickness of the anti-corrosion galvanizing layer required by industrial parts.
5. Water polishing
The surface of the nail-making mechanical galvanizing powder is a non-mirror semi-bright crossing layer, and the water polishing process is the initiator of the mechanical galvanizing of the nail-making machinery and the zinc powder. The plating cylinder continues to rotate, so that the surface of the parts plating to achieve a uniform and bright silvery white surface, generally need to rotate 5-10in, although the plating layer can not reach the mirror luster of the plating, but the smooth surface, brightness is better than the hot-dip galvanized layer. The rotation time of the water-polished plating cylinder has an extreme value, and the zinc plating layer will have a certain nail manufacturing machine degree of cutting failure when the specific maximum value is exceeded.
6. Chrome passivation on the surface of the part
Nail mechanical galvanizing layer, especially under the initial conditions, in humid air, easy to produce white corrosion on the surface of the coating, must be through transparent chromium passivation, yellow chrome blunt, so that the formation of chromium passivation film to prevent the generation of white corrosion.
7. Inspection and acceptance
Nail making machinery industrial galvanizing thickness, plating quality, depending on the process operation, process formula and process qualitative, quantitative specification control: so the quality of the coating testing and identification is particularly important, qualified inspection results will guide the nail mechanical galvanizing process for the correct production of different parts batch size.
