Quality control (QC) and quality assurance (QA) are fundamental components of the API manufacturing process. All steps of manufacturing must meet stringent regulatory requirements set by authorities such as the FDA or EMA. QC involves rigorous testing of raw materials and the intermediate and final products to ensure they meet predefined standards. These tests often include chemical analysis, microbiological testing, and stability studies. QA, on the other hand, encompasses the overall system of procedures and protocols that ensure consistent production quality, including documentation practices, employee training, and validation of equipment.

First, the concept is different
- Third, positive and negative twisting barbed rope appearance is beautiful
- According to the habit often according to the basic galvanized hardware before plating treatment method, as long as it does not contact with water can keep 5~7 years or so without rust, of course, if it is a salt water test, it will not be over 4 hours. Hot dip zinc is to use zinc tin solution to cover the hardware, and the rust prevention time is about five times that of traditional galvanizing. The general outdoor construction is to use hot dip zinc, and the salt water test can do about 36 hours.
- The principle of hot dip galvanizing is simply that clean iron parts are immersed in a zinc bath through Flux wetting, so that the steel reacts with molten zinc to produce an alloyed skin film.

Hot dip galvanized hexagonal net is made of low carbon steel wire by mechanized braided welding and then by hot dip zinc treatment. The net color is white and shiny, thick zinc layer, uniform mesh, flat mesh surface, solder joint tension resistance, high corrosion resistance. The surface of the steel wire is usually protected by hot-dip galvanizing, and the thickness of the galvanized protective layer can be made according to the requirements of customers. Hot-dip galvanizing hexagonal net is another kind of twisting mesh corresponding to the galvanizing hexagonal net.

That said, it can always deform by pulling hard without changing its integrity, so cold drawing has usually reached a limit, which is not a problem, because without this property it increases hardness, which is the desired effect. Cold wire drawing encountered more rain, when the climate is wet, easy oxidation and rust. Therefore, in the storage process should pay attention to avoid rust.

There are three ways to twist the barbed rope: positive twist, reverse twist, positive and negative twist.
- Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is the length of the distance between the lead screw on the zinc pot and 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 in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire galvanized, is an aspect of maintaining the uniformity of zinc layer.
- The use of bundled galvanized wire with the development of industry and agriculture also expanded accordingly. Therefore, galvanized wire products in the industry, such as chemical equipment, oil processing, Marine exploration, transport, electricity, shipbuilding, metal structure, etc.), agriculture (such as sprinkler irrigation, dim room, building (such as water and gas transport, wire casing, scaffolding, house, etc.), Bridges, shipping, etc., has been widely use in recent years. Because galvanized wire goods have beautiful surface, good corrosion resistance and other characteristics, its use scale is more and more extensive.

There are two kinds of use, namely slope protection hook mesh, coal hook mesh, mining hook mesh, coal mine support network, roadway support network. The height of the outer rail of the pavement or seat belt should not be less than 1.10 m. The net distance between balustrade members shall not be greater than 140 mm, and horizontal rail shall not be used. Hook mesh planning is necessary to be safe and reliable, anchor should be installed on the basis of the railings, its strength should meet the requirements of the standard.

- Correction is the hot galvanized wire or cold galvanized wire secondary treatment, the surface after correction is smooth and shiny, and the tensile strength is stronger, so that it is not easy to break. Now it is usually used for screen industry will be changed, which can improve the quality. In addition, clothes rack, communication, high voltage line will be changed to prevent breakage.

- At present, it is recognized that the best surface treatment method for rust prevention is to make dacron rust. Generally, auto parts have been used this method for rust prevention. The salt water test generally lasts more than 96 hours. But if the hardware is used in very poor conditions, there are also people who use “asphalt” which is tar to do the surface treatment.

Widely used in practice, iron wire also has certain harm, simple rust and corrosion, so we can generally use galvanized method to prevent product corrosion. Together in addition to this method, metal commonly used treatment methods and phosphating treatment, oxidation treatment, etc. Metal phosphating treatment: iron and steel products to remove oil, rust, into the specific composition of the salt solution soak, you can form a layer of water soluble salt film on the surface of the metal, this process is called phosphating treatment.

The purchase of blade barbed rope also needs to consider the higher manual installation cost in the later period. Generally, customers only ask the price of blade barbed rope, and sometimes the installation cost is not taken into account in the budget, which is very unreasonable. Because the installation cost is not cheaper than the rope itself, sometimes even the blade rope and column combined. The blade stabbing rope needs a lot of manpower and material resources for installation. In general, the installation cost is also a relatively large expenditure item in the stabbing rope project.

In order to orchard special electric galvanized shaft wire in alluvial surface to partially remove the surface film layer, surface impurity and other shortcomings can be found and solved according to the basic technology; Excessive foam is caused by soap and soapable surface active substances such as human fat into the tank. A moderate rate of foam production would be fine. The large amount of fine homogeneous particles in the tank can stabilize the foam layer, but the accumulation of too much solid particles will cause explosion.

The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

The bonding and anchoring function between cold wire drawing and cold rolled ribbed steel bar and concrete is outstanding. Therefore, when used in components, the phenomenon of cracking of component anchorage area and damage caused by steel wire slip is fundamentally eliminated, and the load-bearing ability and anti-cracking ability of component end are improved. In reinforced concrete structure, the crack width is smaller than that of circular steel bar or even that of hot rolled thread bar.
- The COMBINATION OF disSIMILAR METALS, such as steel and copper, tin, lead and other non-ferrous metals, during hot dip operation, the dissolution of this non-metal will cause the change of zinc film structure. Also like the combination of old and new steel, in pickling operation, the new material is easy to pickling over. In addition, such as part of the processed components, excessive pickling at the processing place is also.

Cold galvanized, generally speaking, do not need heating, galvanized amount is little, this galvanized parts are easy to fall off in wet environment. Hot dip galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal members are attached to a layer of zinc layer. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better.
