Coagulants, such as alum (aluminum sulfate) and ferric chloride, are also employed in sewage treatment. These chemicals assist in the removal of suspended solids, colloidal particles, and turbidity from wastewater. When added to the treatment process, coagulants promote the aggregation of small particles into larger flocs, which can be more easily removed through sedimentation. This process is particularly important in primary treatment phases, where physical separation of solids occurs.

When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well. Galvanized wire, also known as hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.

Stainless steel wire rope is widely used in engineering cranes. It is generally made of many high strength steel wires. It first consists of a single wire wound together to form a strand, and then some of the strands are wound into a rope core, and then the outer strands composed of other strands are wound around the rope core to form a wire rope.
- Nemator roller cage is connected by nemator connecting clasp with longitudinal tension bar fixed on the support, and the connection between longitudinal tension bar and support is selected. The 2.5mm cold-drawn galvanized steel wire is wound 2 times and then tightened and fixed. The bracket is set on the column and the cross side of the protective fence with a span of 3m. Other spans are only set on the upper part of the column, and the bracket and the protective fence are connected with the bracket hoop.

However, in the actual production process, the wire may be affected by other factors that may cause the wire to lose its conductive properties. For example, if the thickness of the galvanized layer is too thick or the surface is not uniform, the current density on the surface of the wire will be uneven, which will reduce the electrical conductivity of the wire. Similarly, if the wire is stretched too much during wire drawing, it may cause the wire to break or the surface to deform, thus affecting its electrical conductivity.
- The coating on the surface of the welding core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.

2, performance characteristics. Zinc coating is thick, fine crystallization, uniform and no pores, good corrosion resistance; Is pure, the zinc plating layer in acid, alkali corrosion slower, such as fog Eng effectively protect tight sand-fixation matrix, the galvanized layer formed after chromate passivation, color white, army green, beautiful and easy, have certain adornment sex, because the galvanized layer has good ductility, and therefore can be rushed, rolling, cold bending and forming and not damage the coating.

There are still some differences between the welding mesh and the wire mesh and the steel mesh. This mesh is mainly a welding mesh made of high quality low carbon steel wire straightened and cut, and then welded with electric welding equipment. It can be said that because of the characteristics of fast production and convenient transportation, it has been applied to many industries. The application of welding mesh in the industry, because the mesh has strong corrosion resistance and uniform mesh. It has become a special grid for floor heating in the building industry and has been applied in many fields.
- In white iron, its carbon and iron together into iron carbide, crack appears white, very strong and brittle quality, for the material of malleable steel. The alloy grade consists of various alloying elements with different compositions and structures. Because alloying elements in iron ore can make copper through the material thickening degree of strengthening, hardness, impact force, strength resistance, closing rate, elongation, so alloying iron in the exercise of high quality iron, is the primary supplementary element.
- The material of the electric welding net is black wire, galvanized wire and wire drawing. The mesh is 1 inch, 2/1 inch, 3/1 inch, 4/1 inch, 4/3 inch, 8/5 inch, etc. Different materials, different mesh, used in different places. Therefore, electric welding net is an indispensable building material in the construction industry.

When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
- Technical product wire, choose a wire special processing, no broken end, zinc amount uniform bright, general quotation slightly expensive. Galvanized silk also contains sprinkling: one plate per volume weight of about 100kg-1000 kg, mainly suitable for industry, agriculture, animal husbandry. Strong corrosion ability, solid coating and other characteristics.
- Hexagonal net weaving methods: positive twist, reverse twist, two-way twisting, first editing after plating, first plating after editing, and then divided into hot dip galvanized hexagonal net, electric galvanized hexagonal net, PVC plastic coated hexagonal net, stainless steel hexagonal net, etc.
