Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.

Galvanized hexagonal mesh features: easy to use; Save transportation costs. It can be reduced into small rolls, and involved in moisture-proof paper packaging, occupying little space. Coating thickness uniformity, corrosion resistance is stronger; Simple construction, no special technology; Strong resistance to natural damage and corrosion resistance and the ability to resist adverse climate impact; Can withstand a wide range of deformation and still not collapse. Play the role of fixed heat preservation and insulation.

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.

The rubber strip is typically made from durable and flexible materials such as silicone or EPDM rubber. These materials are resistant to wear and tear, making them long-lasting and effective at sealing out unwanted elements. The strip is attached to the bottom of the door using adhesive or screws, creating a barrier that blocks out drafts and noise.

Water-activated adhesives are very popular for packing tape. When the adhesive is used on cardboard, the bond it creates is so strong that the tape cannot be removed without damaging the cardboard. As a result, it is the perfect tamper-evident packaging. No one can open a box sealed with water-activated tape without leaving obvious evidence. Water-based is the cheapest of all adhesives.

At its core, a control box is a hub of management for electrical equipment tasked with housing control gear and ensuring the reliable distribution of electricity to machinery, equipment, or systems.
