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℃.
The characteristics of these cages are small, light, easy to carry and easy to clean. For small animal cage, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violence”, otherwise the cage in the “destruction” will occur under the welding or plastic crack.
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.
The external environment has great influence on the preservation of galvanized wire mesh. In the rainy season, it is necessary to pay attention to the air humidity of the workshop, warehouse and other departments. It is recommended to use a humidifier. Usually, the moisture absorption of book paper is larger than that of powder paper, and the pH value is higher. Generally speaking, in the normal environment of storage wire, storage time of two years is not corroded wire phenomenon. However, it should be noted that in the process of handling the iron wire, it should be handled gently to avoid the position of the coiling coil, which will cause the smooth pulling of the wire and affect the production.
Different from the general zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach the former 6-8 times, so in the service life also has a great advantage, ordinary products three or five years began to corrosion and the latter will take longer to change. Stainless steel barbed rope is in the material aspect of protection, so the durability is also better, these two products are long in the service life, but in the price is high.
3. Put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and it is an important measure to stabilize the PH value in a numerical range. At the same time, it is convenient for the filter to filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.
Spray powder mainly acrylic powder, polyester powder and so on. Dipping is a kind of plastic coating process, that is, the plastic coating on the matrix, generally metal, such as: daily use of clothes hangers, pliers handles, scissors on the rubber sleeve, various handrails, etc. Plastic immersion is to heat the metal to spray plastic powder evenly on the metal to form a plastic film, or heat immersion liquid into the metal to cool it and then plastic coating on the metal surface.
Even so, when they come out, they will uncover the mess, even though they know they will be punished, but only in a cage.) If you have time to refer to some foreign dog books, also strongly advocate cage training as a puppy. Before starting cage training, the cage is padded with a water bottle, some fun toys and bones to chew on. The cage door must be opened. Order the dog into the cage, then lure it into its new den with tasty cookies.
Heavy hexagonal mesh is made of steel wire woven into hexagonal mesh by special machinery. This kind of mesh, after cutting and assembling, can be made into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, assembly, etc.
