8. Meet specific requirements: For those structures or equipment that need to be operated under specific environmental conditions or used for a long time, such as Marine engineering, chemical equipment, etc., high chlorination anticorrosive primer can provide customized protection solutions.

In short, the use of high chlorination anti-corrosion primer is to ensure that the coating structure or equipment can be effective and durable anti-corrosion protection under various environmental conditions, thereby extending its service life, reducing maintenance costs and improving overall performance.

 

4. Which surfaces are high chlorinated anti-corrosion primers suitable for?

High chlorinated anti-corrosion primers are mainly suitable for metal surfaces, especially those susceptible to corrosion. The following are some surfaces commonly used with highly chlorinated anti-corrosion primers:

1. Steel: including carbon steel, alloy steel, stainless steel, etc.

2. Iron: Commonly used in buildings, infrastructure and other structures.

3. Aluminum: Although aluminum itself has a certain corrosion resistance, it may still require additional corrosion protection in some application environments, such as Marine environments or chemical environments.

4. Other metals: such as zinc, copper, etc., although they themselves have a certain degree of corrosion resistance, but in some specific application environments may still need the additional protection of high chlorination anticorrosive primer.

5. Welding site: The metal surface after welding usually becomes more prone to corrosion, so the use of high chlorination anticorrosive primer can provide additional protection for the welding site.

6. Pre-treated surface: After the metal is pre-treated with grinding wheel, grinding or pickling, the use of high-chlorinated anti-corrosion primer can enhance its anti-corrosion performance.

In short, high chlorinated anti-corrosion primers are mainly suitable for those metal surfaces that are susceptible to corrosion to provide effective anti-corrosion protection and extend their service life. When selecting and using high chlorination anti-corrosion primer, it should be considered according to the specific metal type, application environment and performance requirements.

 

5. Do the construction temperature and humidity of high chlorination anticorrosive primer affect it?

Yes, the construction temperature and humidity of high chlorination anti-corrosion primer do have an impact on its coating effect. We need to consider what effect the construction temperature and humidity have on the high chlorination anticorrosive primer

First, construction temperature:

1. Drying time: The construction temperature below the recommended range may prolong the drying time of the primer, resulting in a prolonged construction period.

2. Curing effect: Low temperature construction may affect the curing effect of the primer, reducing the strength and durability of the coating.

3. Fluidity and coating property: Construction within the recommended temperature range can ensure that the primer has good fluidity and coating property, improving the uniformity and appearance of the coating.

Second, construction humidity:

1. Coating drying: High humidity may delay the drying process of the primer and increase the risk of coating damage, such as flow marks, bubbles or other coating defects.

2. Coating adhesion: Excessive humidity may affect the bonding between the primer and the substrate, reducing the adhesion of the coating.

3. Solvent volatilization: When the humidity is high, the solvent in the primer may not easily volatilize, resulting in high solvent content in the coating, affecting the performance and stability of the coating.

Therefore, before the construction of high chlorination anticorrosive primer, the temperature and humidity of the construction environment should be carefully considered and controlled. Usually, manufacturers will provide recommended construction conditions and restrictions in the product technical data sheet, and it is recommended to strictly follow these guidelines to ensure the best results for the coating process and coating properties. If construction is required under specific environmental conditions, special formulations or additional coating measures may need to be used to meet the requirements of the product.
