One of the standout contributions of PQC 2020 was the emphasis on diversity in algorithm design. The conference showcased several candidates for standardization that leverage different mathematical problems. These include lattice-based cryptography, code-based cryptography, multivariate quadratic equations, and hash-based signatures. Each of these approaches offers unique advantages and weaknesses, which are crucial for establishing a secure post-quantum cryptographic landscape.

- Galvanized wire coating is galvanized, aluminum plated, coated with nylon or plastic, etc. Zinc is divided into thin coating of steel wire after plating and thick coating of galvanized steel wire after drawing. The mechanical properties of thick coating are reduced compared with smooth steel wire rope, which should be used in severe corrosion environment. It is more resistant to corrosion, wear and heat than galvanized wire rope, using the first plating and then drawing method of production. Coated nylon or plastic wire rope is divided into two kinds of coated rope and coated stock after the rope.

Post time: 12-01-23 - Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.
- Twisting hexagon mesh production factory is the selection of low carbon steel silk woven, mesh structure he has corrosion resistance, high strength and ductility and so on. The diameter of steel wire can reach 2.0mm-4.0mm. The surface of steel wire is usually used for hot-dip galvanized maintenance. The thickness of galvanized maintenance layer can be made according to the needs of customers.
- 5. The bird cage should be sprayed with transparent wood environmental protection paint every 1-2 years. This protects the cage’s skeleton from the effects of weathering.
- The diameter of the wire is generally 0.3mm – 3mm, after the wire is not very strong, need to annealing, annealing this step is very important, can ensure the production of galvanized welding net, with good elasticity and toughness. After welding, the welding mesh becomes black wire welding mesh and can not be put on the market, because its corrosion resistance is poor and the service life is short, so it needs to be galvanized or dipped plastic treatment.
- B. When the thickness of the plating is greater than 4 mm, the zinc adhesion should not be less than 610g/m, that is, the average thickness of the zinc layer should not be less than 86 microns.
- 2. Preheating: Put the steel wire into the preheating furnace to increase its temperature in order to better react with the molten zinc liquid.

1. Eliminate caked zinc residue on zinc liquid surface

Hot dip galvanizing of steel plate is also called hot dip galvanizing. Zinc ingots are melted in the tropics and some auxiliary materials are added in hot dip galvanizing. The steel grid parts are then soaked in a galvanizing tank and a galvanizing layer is attached to the steel plate. The strength of hot dip galvanizing depends on its corrosion resistance, and the adhesion and hardness of galvanized sheet are better. The amount of galvanized steel plate after galvanizing. So this is the general amount of zinc.
- 2. Breeding small animals such as chickens, ducks and geese, enclosure protection for fruit trees and gardens, and protection for medium-sized breeding, it is recommended that you choose products with a wire diameter of 2.3mm-2.5mm.

Stainless steel is short for rust acid steel, air, steam, water and other weak corrosion medium or stainless steel is called stainless steel; And the chemical corrosion resistance medium (acid, alkali, salt and other chemical etching) corrosion of steel called acid steel.

Post time: 09-05-23 - U nail price selection of galvanized iron wire, hot dip galvanized iron wire and black iron wire and other high-quality wire, welded, PVC or PE, PP powder after curing coated its surface, with strong adhesion, good corrosion resistance, bright color and so on.

The more turns thorn rope, at the same time will shorten some use the length, but its tensile strength is improved and barbed wire manufacturer production products general laps for the 3 ring, very few customers to use the product requires 5 laps, this time both in processing fees and use the length is calculated need extra.
- Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is to use the lead screw above the zinc pot, the length of the distance to the ceramic sinking roller. Thick wire diameter zinc dipping time should be long, fine wire diameter zinc dipping time should be short, zinc dipping length is in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire, is an aspect of maintaining the uniformity of zinc layer.

In moist air, a dense basic zinc carbonate film forms on the surface of zinc. Zinc coating belongs to the anodic coating, it is mainly used to prevent the corrosion of steel, its protective performance and the thickness of the coating is very important. The protective and decorative properties of zinc coating can be improved significantly after passivation treatment, dyeing or coating with light protection agent.

Blade barbed rope is a new product of safety protection supplies, and other barbed rope is different with very sharp blade, its production process is the stainless steel sheet stamping forming. The blade barbed wire protective net is a new kind of protective net. The blade barbed wire produced by our factory is made of corrosion-resistant hot-dip galvanized steel plate or stainless steel plate.
