Introduction

Deep sea detection equipment plays a crucial role in marine scientific research, resource exploration and environmental monitoring. However, extreme conditions in deep-sea environments, such as high pressure, low temperature, high salinity and corrosiveness, put extremely high requirements on the material and performance of the equipment. To ensure the long-term and stable operation of the equipment in a deep-sea environment, it is crucial to select the right materials and catalysts. This paper will explore the durability of the reactive low-odor amine catalyst ZR-70 in deep-sea detection equipment, analyze its performance parameters, application advantages and performance in actual use.

2. Environmental challenges of deep-sea detection equipment

2.1 High voltage environment

The pressure in a deep-sea environment increases sharply with the increase of depth. For every 10 meters of water depth, the pressure increases by about 1 atmosphere. In the deep sea thousands of meters, the pressure can reach hundreds of atmospheric pressures, which puts high demands on the sealing properties of the equipment and the strength of the material.

2.2 Low temperature environment

The deep sea temperature is usually between 0-4°C, and the low temperature environment will affect the mechanical properties of the material and the rate of chemical reactions, resulting in a degradation of equipment performance.

2.3 High salinity environment

Seawater contains a lot of salt, and a high salinity environment will accelerate the corrosion of metal materials and affect the long-term durability of the equipment.

2.4 Corrosive environment

There are a variety of corrosive substances in the deep-sea environment, such as hydrogen sulfide, carbon dioxide, etc., which will accelerate the corrosion and aging of materials.

3. Application of ZR-70 in deep-sea detection equipment

3.1 Catalyst selection criteria

In deep-sea detection equipment, the following factors need to be considered when selecting catalysts:

Catalytic Efficiency: It can maintain efficient catalytic activity under low temperature and high pressure environments.
Chemical stability: It is not easy to decompose or fail under high salinity and corrosive environments.
Environmentality: Low volatility and low toxicity, reducing pollution to the marine environment.
Durability: Maintain stable performance during long-term use, reducing maintenance and replacement frequency.

3.2 Application advantages of ZR-70

ZR-70 performed well in the above standards, and its high-efficiency catalytic, low odor, environmental protection and stability make it an ideal catalyst choice in deep-sea detection equipment.

3.3 Practical Application Cases

3.3.1 Sealing materials for deep-sea detectors

In the sealing material of the deep-sea detector, ZR-70 is used as a catalyst for the preparation of polyurethane foam. Polyurethane foam has good sealing and pressure resistance, and the low temperature catalytic activity of ZR-70 ensures that the foam isRapid curing in deep-sea low temperature environments, while its low volatility reduces the release of harmful gases in the foam and protects the health of operators.

3.3.2 Paints for deep-sea detectors

ZR-70 is used in the preparation of deep-sea detector coatings, and the coatings must have good corrosion resistance and adhesion. The efficient catalytic action of ZR-70 ensures rapid curing of the coating in low temperature and high pressure environments. At the same time, its chemical stability makes the coating difficult to decompose during long-term use, extending the service life of the equipment.

3.3.3 Adhesives for deep-sea detectors

The selection of adhesive is crucial during the assembly of deep-sea detectors. ZR-70 is used as a catalyst for the preparation of epoxy resin adhesives, ensuring rapid curing and high-strength bonding of the adhesive in deep-sea environments. At the same time, its low odor properties reduce the release of harmful gases during the use of the adhesive.
