Polyurea: Taking Action in Disaster Resistance and Relief

Issuing time:2025-02-18 15:13

Henan experienced a "once-in-a-century" heavy rainstorm, and this disaster has gripped the hearts of people across the nation. The continuous torrential rains have flooded roads, subways, and other public facilities in many parts of Henan, leaving people stranded. Numerous rescue equipment and tools have been mobilized nationwide to participate in the emergency response. Among them, speedboats and rescue boats, known as "boats of life," have played a crucial role in flood rescue operations. As highly efficient and practical tools for flood control and rescue activities, they have fully demonstrated their agility, flexibility, and effectiveness in flood relief efforts.

Fiberglass speedboats and rescue boats possess strength comparable to steel, excellent stability, and are suitable for use in high winds, rough waves, and strong currents. They offer high safety and are most commonly used in harsh disaster rescue conditions. Aluminum alloy speedboats and rescue boats, on the other hand, are characterized by their low density, lightweight, portability, durability, and ease of launching. They are more frequently used after floodwaters have stabilized.

However, whether made of fiberglass or aluminum alloy, if no protective measures are applied, the hulls can suffer damage and thinning due to frequent friction and environmental erosion. Damage caused by sharp or hard objects during rescue operations can significantly shorten the lifespan of these lifeboats and rescue vessels.

How can this problem be solved? Polyurea high-performance safety coatings are the best choice! They exhibit excellent adhesion to both fiberglass and metal substrates and are lightweight, adding no extra weight to the hull. By forming a dense protective layer on the hull's surface, polyurea coatings provide effective protection with their superior physical properties. They are not only waterproof and corrosion-resistant but, most importantly, wear-resistant and impact-resistant, preventing damage caused by complex environments during rescue operations.

Even during non-rescue periods, this "protective layer" eliminates the need for additional anti-corrosion measures and significantly enhances the hull's aging resistance, reducing the maintenance costs of rescue vessels.

In addition to the two types of hulls mentioned above, rubber inflatable motorboats are more practical during search and rescue operations, especially when rescuing a small number of people in villages or remote areas. These boats are highly flexible, easy to transport, and can be inflated and used on demand. They also provide excellent impact resistance and cushioning. However, their biggest drawback is their fragility—they are prone to wear, scratches, damage, punctures, UV degradation, and chemical corrosion. Once the hull is cracked, the boat cannot be used until repaired, and metal parts require additional anti-corrosion treatments.

Polyurea high-performance safety coatings are aging-resistant, corrosion-resistant, and exhibit excellent thermal stability. They also possess outstanding impact strength, flexibility, and wear resistance. When sprayed onto hulls, they address the shortcomings of speedboats and rescue vessels, enhancing their performance and improving rescue effectiveness! Additionally, when applied using professional equipment, polyurea gels in just 10 seconds and cures rapidly. It can be sprayed onto any curved surface without sagging, ensuring no impact on the shipbuilding schedule.

While we cannot intervene in natural disasters, we can strive to improve rescue capabilities and the safety standards of rescue equipment, making our rescue operations more efficient and safer! Currently, Aierjiajia's high-performance polyurea safety coatings have been applied to numerous vessels. Having withstood the test of harsh environments time and again, they have proven their exceptional performance! It is believed that in the near future, polyurea high-performance safety coatings will become the standard coating for all types of rescue vessels, leveraging their unique technical advantages!
