Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.

On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.

6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.

Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.

Under any application environment, users hope that the welding mesh has better strength, as long as it has improved in strength, it will make better use of the demand, but to make the strength of this product improve, also need to have many conditions, to see what kind of data manufacturers have in production, the strength of the product is the strength of the data, But a manufacturer does not meet the strength requirements in the data, and naturally, it cannot make the strength of the product improve after all, so this is the condition.

High-speed road guardrail net, hexagonal mesh of all kinds of guardrail net, the value of the high-speed road is more prominent, it is not only used in a variety of roads, in a variety of sports ball fields and landslides to take care of, but also to reach a very close utility.

Some customers just use ordinary fences, but the pictures provided to the barbed rope factory are really used in the barbed rope products of prison, maybe because the customers prefer the style, but such products are really a little overqualified to be installed in ordinary areas. Even if customers prefer such barbed rope products, the high price is also prohibitive. The price and quality of the prison application barbed rope is certainly not the level of the barbed rope we contact in daily life.

Stainless steel blade barbed rope production process is basically similar to galvanized blade barbed rope production process, usually according to the mold to determine the size of the blade.

The application range of positive and negative twisted barbed wire is also very wide. It is a good choice for purchasing barbed wire. So what are the advantages of positive and negative twisted barbed wire compared with other barbed wires? The following  barbed wire factory will introduce the positive and negative twisted wire in detail. Three advantages of rope

Now most people want to choose a few when choosing barbed wire material better thorn rope, but the special barbed wire the better, not right, it is important to choose which model is most suited to their own thorn rope,, although is very simple product, but in the use of these products are for specific situation is different, and has a different effect, Maybe now consumers do not have too much concept of blade barbed rope, in fact, such barbed rope products have a higher safety factor. In addition, there are also more and more barbed rope, dazzling reasons, here is an example to illustrate the choice of special barbed rope.

The size of the galvanized layer of galvanized iron wire is related to the anti-corrosion ability and application effect of galvanized wire. The thickness of the galvanized layer of the general standard galvanized wire products should be tested after the product is formed. There are three specific test methods. Weighing method and cross section microscopy method are destructive experimental methods, and magnetic method is a relatively rigorous non-destructive method, but the measurement steps and requirements are relatively high, so they are rarely used in specific applications. The first two methods are intuitive and common methods.
