The process of coagulation typically involves several stages, starting with the addition of the coagulant to the water. This addition is usually followed by rapid mixing to ensure that the coagulant is evenly distributed and can interact with impurities. After the initial mixing, the water undergoes flocculation, a gentle stirring process that allows the newly formed flocs to gather and grow larger. Finally, the water goes through sedimentation, where the flocs, being heavier than water, gradually settle at the bottom of the treatment tank, leaving clearer water above.

- The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.

Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

Hexagonal guardrail net custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, is prone to fracture, lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail net and extend the service life of the product.

Galvanized hexagonal mesh is a kind of galvanized metal wire mesh, the mesh shape is hexagonal.
- Steel mesh benefits: Compared with traditional handmade steel mesh, steel mesh has better elasticity and even spacing. When pouring concrete, the steel mesh is not easy to bend, and the thickness of concrete protective layer is easy to control and even. In bridge deck surfacing, measure the protective layer of steel mesh. The pass rate is 95 percent.
- In fact, although galvanized hook net is a useful material for iron products, but fundamentally speaking, modern hook net through continuous transformation and improvement, even if it seems to be not useful products, also have a role in its use, here we can turn our attention to people abandoned galvanized hook net.
- Selection of cage size tips
- Plastic spraying is often referred to as electrostatic powder spraying. It is the use of electrostatic emitter to make plastic powder charged, adsorbed on the surface of the iron plate, and then baked at 180~220℃ to melt the powder and adhere to the metal surface. Plastic spraying products are mostly used in indoor boxes, and the paint film appears flat or matte. Spray powder mainly acrylic powder, polyester powder and so on.

Hot dip galvanizing is to remove oil from the workpiece, pickling, dipping, drying after dipping into the dissolved zinc solution for a certain time, can be brought out. Hot dip galvanizing is an effective way to prevent corrosion of metal. It is mainly used for metal structure facilities in various industries. It is to immerse the steel parts after rust removal into the melting zinc liquid at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anti-corrosion. The galvanized layer is more firm.

With the development of mining industry, pig iron classification in Our country has been very extensive, to meet the needs of the machinery industry. Generally speaking, iron wire factory produces galvanized iron wire iron can be divided into two categories, is directly from the iron ore through iron tracing exercise out of the metal, the primary components of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, the elements such as carbon, silicon, manganese and so on are mixed in, so that the refined data is called – like general pig iron, also for the initial grade of the material.
- Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.

Use of stainless steel welding mesh:
- Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.
