3. Moisture and Termite Resistance Gyproc PVC false ceilings are exceptionally resistant to moisture, making them suitable for areas prone to humidity, such as bathrooms and kitchens. This characteristic helps prevent mold and mildew growth, ensuring a healthier indoor environment. Moreover, their termite resistance offers longevity and peace of mind, particularly in regions where pest infestations are common.

The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.

3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag

The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.
- Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by the customer, ensure that the metal wire can achieve the role of rust and corrosion prevention, and meet the service life required by the customer. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound with an inward end to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test. This item is determined according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
- Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.
- Hexagonal net structure can be used for slope support, excavation, rock surface net mine support form, slope vegetation (green color), railway road isolation block, it can be made into a cage, cushion, used for rivers, flood DAMS and seawall erosion protection and reservoir, river closed cage. Driving and directing river, river flood disaster is a major erosion of water river damage, resulting in flooding, resulting in a great deal of loss and property subjected to the amount of water and soil dissipation. Because of this, in dealing with these problems, the application of a lifestyle grid structure becomes a solution plan that has the potential to protect the bank forever.
- Widely used in mining, petroleum, chemical industry, construction, mechanical accessories, protective net, packaging net, barbecue net, barbecue oven net, sintering furnace net, hardware products with net, hardware products with net, arts and crafts with net, vibrating screen net, net basket, food machinery with net, barbecue with net, wall net, grain with net, highway, railway, infrastructure with net.
- We have to carefully choose a good cage for the parrot, so that it has a comfortable home.
- Because of the pre-tension given to the packaging and binding of galvanized wire, it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, no fracture, strong elasticity, ordinary steel lines and rebar are difficult to compare. The use of advanced galvanized finishing process, therefore, the use of hot-dip galvanized steel wire construction, not only good corrosion resistance, but also beautiful and generous. The product has the characteristics of smooth surface, high dimensional accuracy, good uniformity of zinc layer and strong adhesion.

Galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire is widely used. Electroplating temperature should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.
- Galvanized hexagonal mesh uses: building wall fixed, heat preservation, heat insulation; Power plant piping, boiler heating; Anti-freezing, residential protection, landscaping protection; Raise chicken and duck, isolate chicken and duck house, play the role of protecting poultry; Protect and support seawalls, hillsides, roads and Bridges and other waterworks.
- Great attention should be paid to pickling of large rolls of galvanized wire. Acid is highly corrosive. Therefore, when adding acid, the acid must be poured into the water, and it is along the wall of the cylinder, and not thrown down at once, so as not to cause splashing. Remember the order of acid pouring, acid into water rather than water into acid, water into acid will cause splashing and boiling, when pouring acid must wear protective glasses, beside must ensure that there are no non-professional people watching, so as not to cause some acid splashing danger.

Post time: 16-02-23 - Galvanized wire can be seen as iron wrapped in carbon, when extinguished, the surface is comparable to shallow carbon can contact with oxygen, produce carbon dioxide gas, will wrap it in iron (this is a molten state) radiation in. The more carbon there is in the galvanized wire, the more likely it is to spark. The iron-encased carbon is like dynamite in a dynamite bag, blowing the iron away from time to time.
- 3, whether positive and negative twist, whether bilateral silk is needed.

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.

3. Quality test report

Compared with the traditional barbed and twisted barbed rope, the raw material cost is relatively high because of the relatively complex process.
- 2: plastic spraying blade barbed rope characteristics of beautiful color, according to the use of the environment to choose the color, so that it and the surrounding environment. Paint color including grass green, dark green, black, red, white and so on.
