aluminum screen frames

Now it is more used in the binding of the construction industry. Compared with ordinary iron wire, it is softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. More kinds, can be selected according to different uses, making annealing wire device is simple, improve the utilization rate of the device. The material properties of annealed wire can meet different processing requirements.

The service condition and service life of electro galvanized iron wire or component are closely related to the thickness of electroplated coating. The more strict the conditions of use and the longer the service life, the thicker the layer of galvanized iron wire required. Different products, according to the specific environment (temperature, humidity, rainfall, atmospheric composition, etc.) to determine the expected service life of the coating thickness, blind thickening will cause all kinds of waste. But if the thickness is insufficient, it will not reach the expected service life requirements. Different manufacturers, according to their own equipment conditions, in the case of determining the plating, the first preparation of a more complete and reasonable process flow, clear plating parameters, control plating solution concentration, standard operation.

1. Eliminate caked zinc residue on zinc liquid surface

The screen is made into a box-like container, with stone filled with cages, can be used to protect and support seawall, hillside, road and bridge, reservoir and other civil engineering, flood control and flood resistance is a good material.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, The softness is also very uniform, the color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry, etc.

This method is generally the use of hot rolled laminated plate as raw material, the annealed steel plate is first sent to the pickling workshop, with sulfuric acid or hydrochloric acid to remove the surface of the steel sheet oxygen hot galvanizing method. After pickling, the steel plate immediately enters the tank to soak and wait for galvanized, which can prevent the reoxidation of the steel plate. After pickling, water cleaning, squeeze dry, drying, into the zinc pot, the temperature has been maintained at 445-465℃.

Now hexagonal net is used in a large number of Bridges, piers and bridge buttress inclined plane protection, bridge buttress inclined plane there are many kinds, people according to the inclination of the inclined plane to choose the right hexagonal net, when the inclined plane gentle, people generally use gabion slope protection system, and in the case of steep slope, people will use gabion mesh gravity protection wall.

Welding mesh is widely used in industry, agriculture, breeding, construction, transportation, mining and other aspects. Such as machine shields, animal fences, flower fences, window fences, access fences, poultry cages, egg baskets and home office food baskets, paper baskets and decorative. We can make it according to the special requirements of customers. Welding mesh is made of high quality low carbon steel wire row welding, and then cold plating (electroplating), hot plating, PVC plastic coated surface passivation, plasticizing treatment, smooth mesh, uniform mesh, solid solder joint, local machining stable performance, corrosion resistance, corrosion resistance. Features: Stainless steel mesh selection of high quality stainless steel wire row welding, more acid, alkali resistance, solid welding, beautiful, widely used and so on.

Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.

4. Keep the rinse water clean after pickling the steel wire

In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.
