To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the amount of surface-active substances brought in to Z. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh box, the inside of the filler are selected stones, these stones are not easy to wear, and between the stones and stones will retain some gaps, so it is very good to meet the drainage requirements.

Stainless steel material refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion of steel, also known as stainless acid-resistant steel. In practical application, the steel that is resistant to weak corrosive medium is often called stainless steel, and the steel that is resistant to chemical medium corrosion is called acid resistant steel. And galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in construction, handicrafts, silk mesh, highway fence, product packaging and daily civilian and other fields.

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 customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided 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.

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.

The technical term “galvanized” means that metal has been specially treated with zinc. Essentially, the wire is covered with a very thin layer of zinc. It is this thin layer of zinc that gives galvanized wire its many properties. Galvanizing can be done by dipping wire into a pool of zinc or by electroplating. Are you familiar with galvanized wire mesh? Do you know what to pay attention to in the process of use?
