Rust inhibitor(WS B-100d)

This product is mainly composed of organic phosphine copolymer, film former, surfactant, metal pre-filming agent and other compounds. It can chelate with iron ions in water and form a thin and dense anti-corrosion film on the surface of carbon steel. It has the advantages of fast film formation, fine and uniform film quality, strong stability, low toxicity and no pollution. An ideal cathode type p

Product Detail

◇ Features and uses:

It is worth noting that the conventional pre-filming agents of other companies are generally alkaline pre-filming (or passivation), while the alkaline (or passivated) pre-film will pitting the copper (or carbon steel) material in the pipeline. This is the place to pay attention to, and the company's WS B-100d agent is a neutral pre-film type agent, which can protect metal materials, is non-toxic and safe to use.

This product is mainly used to form an anti-corrosion film on the surface of the heat exchanger metal of the open circulating cooling water system. It has excellent effects on the corrosion protection of water-cooled equipment in water pipelines. For example: the new equipment circulating cooling water system or system maintenance, cleaning of the heat exchange equipment and the pre-film of the pipeline, so that the metal surface forms a protective film to prevent corrosion of carbon steel, copper alloy, stainless steel and other materials during operation.

◇ Appearance:

Light yellow liquid

◇ How to use:

The dosage is 200-400 mg/L, the pre-filming time is 48-72 hours in the cold state, and the hot state is 24-48 hours. Another addition of scale inhibitor and dispersant 100 mg / L, pH 6-7 is the best.

◇ Powdered solid anti-rust corrosion inhibitor WS B-100d compared with a brand of liquid pre-filming agent (or passivating agent):

Contrast content	Powder anti-rust pre-film corrosion inhibitor WS B-100d	Other liquid pre-filming agents (or passivating agents)
Characteristics	The company's B-100 agent is a neutral agent with fast film formation, fine and uniform film quality, good chemical stability, high efficiency and reliable protection of equipment metal, and no damage to steel, copper and rubber.	Other companies are alkaline pre-films (or passivators) that, if not handled properly, will be highly corrosive to metal pipes and can easily damage equipment.
effect	An anti-corrosion film is formed on the surface of the heat exchanger metal of the open circulating cooling water system. It has excellent effects on the corrosion protection of water-cooled equipment in water pipelines.	The effect is general and extremely destructive to the pipeline. For example, chemical passivation is caused by the direct action of an oxidant such as concentrated HNO3 on a metal to form an oxide film on the surface, or by adding an easily passivated metal such as Cr or Ni.
Adaptation	Applicable to a wide range of water quality, strong adaptability to water quality is not affected by harmful ions such as copper and iron in the water, mainly used for pre-filming of heat exchange gas equipment and pipelines after the new device of the circulating cooling water system is started or after system maintenance. The metal surface forms a protective film to prevent corrosion of carbon steel, copper alloy, stainless steel and other materials during operation.	The effect is general and extremely destructive to the pipeline. For example, chemical passivation is caused by the direct action of an oxidant such as concentrated HNO3 on a metal to form an oxide film on the surface, or by adding an easily passivated metal such as Cr or Ni....
The cost	The general dosage is 200 ppm (that is, 200 g of one ton of water), the cost of use is greatly reduced, and it can be added after the dissolution is completed.	The dosing concentration is at least 1000 mg/L (that is, 1 kg of water per ton), which is particularly expensive to use. If the amount is not enough, directly corrode the pipeline! ! !
Environmental safety	It is non-toxic, safe and convenient to operate, and does not affect the environment and the health of operators.	It is toxic and does not meet environmental protection standards, causing secondary pollution to the environment to be harmful to the health of operators.
