Moreover, self-drilling screws offer exceptional pull-out resistance, meaning they stay put under various stresses, including wind uplift, a common concern in roofing projects

Post time: 23-09-22- Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives shall be used to obtain a coating that meets the requirements of this standard. Luminescence treatment should be carried out after luminescence plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied to activate 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
In order to remove the photosynovium and oxide remaining on the surface of galvanized iron wire after drawing or heat treatment, it is necessary to do the surface treatment of galvanized steel wire before plating. The common surface of low carbon steel wire is the light synovium or oxide of animal or vegetable oil; Medium and high carbon steel in addition to contain animal or vegetable oil components.
- Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. If it is a hexagonal metal galvanized layer of metal wire, the wire diameter is 0.3mm to 2.0mm metal wire, if it is a PVC coated metal wire braided hexagonal net, the use of 0.8mm to 2.6mm PVC(metal) wire. Twisted into a hexagonal shape, the outer frame edge of the line can be made into a unilateral, bilateral, movable silk.
When the coating of large galvanized wire is blistered in the process of galvanizing, the bath temperature should be checked first. If the bath temperature is not low, and then strengthen the removal of oil before plating, to prevent the base metal in acid corrosion. If you pay attention to these problems, the bubbling phenomenon still exists, it should pay attention to the dosage and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, to reduce the content of additives, observe whether the bubbling phenomenon is improved. If there is no improvement, check whether the additive has been stored for too long or whether it contains too many impurities.
In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting. In the debugging of zinc wire dipping distance, keep the original speed unchanged, according to the time of dipping zinc, the diameter of steel wire, and then estimate the dipping distance. By adjusting the zinc immersion distance, the zinc immersion time of steel wire of various specifications is shortened by 5s on average compared with that before debugging, so that the zinc consumption per ton of steel wire is reduced from 61kg to 59.4kg.
Some customers do not understand the range of application of different styles of barbed rope, so there is a big difference.
- 1, we should pay attention to the welding mesh moisture-proof: if it is just the general outdoor air humidity, do not bother. If the weather is foggy, use dry cotton cloth to wipe the bead on the welding mesh; If it rains, you should dry the water when the rain stops. Try to maintain and prolong the life of the welding mesh.
- Post-plating (passivation, hot melting, sealing and dehydrogenation, etc.) for the purpose of enhancing protective properties, decoration and other special purposes. After galvanized, chromate passivation or other conversion treatment is generally required to form the corresponding type of conversion film, which is one of the key processes to ensure the quality of post-plating.
- Carbon spring steel wire current national and occupational recommendation specifications are divided into two types: one is cold deformation steel wire, also known as cold tension spring steel wire. Cold drawn carbon spring steel wire is first quenched by lead to obtain soxhlet arrangement, and then the surface phosphating, with a large surface reduction rate drawn to the finished scale, the steel wire arrangement is fibrous, has high tensile strength and elastic limit, good winding and change function.
For mountainous or hilly areas where the ground is more undulating set up stakes. You need to set a stake at the beginning and the end, and then determine the position. In the middle of the ups and downs, to increase the stakes according to the complexity of the ups and downs of the terrain, we need to be able to see 3 stakes at the same time, so that the installation is. It’s a straight line.
The use of packaging galvanized wire with the development of industry and agriculture is also expanded accordingly. Therefore, galvanized silk commodities have been widely used in industry (such as chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding, etc.), agriculture (such as irrigation, heating houses), construction (such as water and gas transportation, wire casing, scaffolding, houses, etc.), Bridges, transportation, etc., in recent years. Because galvanized silk products have beautiful surface, good corrosion resistance and other characteristics, its use is more and more extensive.

- 3. The transport, storage and use of the binder of galvanized wire mesh should adopt safety and fire prevention methods according to the relevant regulations, so as to be safer.
Post time: 20-10-22- Because they are afraid of the rain, so there is no need to say more, and the surface of the packaging is more afraid of the sun, so it is not recommended to prevent the outdoor blade thorn rope will cause the woven bag to become ineffective, resulting in the internal blade thorn rope exposed to affect the later use.
