Jinlong special fabric (environmentally friendly developed by Hubei Jinlong New Materials Co., Ltd.)Breeding pool clothAs an example, the anti-corrosion design highlights are significant, providing a safe, stable, and efficient solution for aquaculture through material innovation, structural optimization, and functional integration. The core design highlights and effects are as follows:

1、 Material selection: Anti corrosion barrier of polymer composite materials

1. PVC/EPDM rubber substrate

Using high-quality PVC or EPDM rubber as the core material, these two materials have natural chemical corrosion resistance and can effectively resist common acidic substances (such as organic acids produced by organic matter decomposition) and salt erosion in aquaculture environments. Experimental data shows that its service life can reach 8-10 years, far exceeding the 3-5 years of traditional PE fabric, significantly reducing long-term replacement costs.

2. Non toxic and environmentally friendly formula

Through SGS international safety certification, we ensure that there is no plasticizer precipitation in the materials, eliminating chemical hazards to farmed organisms (such as fish and shrimp) from the source. In projects such as Hanjiang Sturgeon Valley, the use of this fabric significantly reduced the deformity and mortality rates of farmed organisms, verifying its biological safety.

3. Addition of UV resistant additives

For long-term exposure scenarios, anti UV additives are added to ensure that the fabric does not crack or fade after more than 5 years of outdoor use, adapts to extreme weather conditions of -20 ℃ to 40 ℃, and ensures the durability of anti-corrosion performance.

2、 Structural design: multi-layer composite and modular anti-seepage

1. Double sided PVC coating process

Through internationally leading coating technology, a dense protective film is formed on the surface of the substrate, effectively blocking rainwater infiltration and sand and dust intrusion, while preventing corrosive substances in groundwater from reverse osmosis, protecting the stability of the aquaculture pond structure.

2. Modular splicing design

The fabric supports customized sizes and shapes, achieving seamless splicing through heat sealing or high-frequency welding processes, avoiding leakage and corrosion problems caused by gaps in traditional soil ponds. At the shrimp farming base in Lianyungang, Jiangsu, modular design ensures that the salinity stability error of the water is controlled within 0.5 ‰, and the survival rate is increased from 65% to 88%.

3. Tear resistant reinforcing rib

Built in 7 reinforcing ribs, each evenly distributed with 3 rope fabrics, combined with 26 galvanized eye circles (stainless steel material) and a multifunctional rope system (7 waist ropes, 4 corner ropes, etc.), enhance the overall tensile strength of the fabric and prevent the invasion of corrosive media caused by external tearing.

3、 Function integration: intelligent monitoring and disease prevention and control

1. Compatibility of embedded sensors

The fabric can be embedded with water quality sensors and meteorological monitoring equipment to collect real-time data on pH, dissolved oxygen, temperature, etc., and automatically adjust through intelligent system linkage with devices such as aerators and feeders. For example, in factory farming, after AI cameras recognize the behavior of fish schools, the multi-layered three-dimensional structure supported by fabric increases the yield per unit area by 40%, while the feed conversion rate increases by 15%, reducing the corrosive substances produced by the decomposition of residual feed.

2. Anti algae and antibacterial surface treatment

The smooth surface design of the fabric suppresses the growth of algae and reduces the transmission of disease vectors. Combined with intelligent monitoring systems, disease risks can be predicted up to 3 days in advance, reducing the probability of large-scale infections. In the shrimp breeding base in Huzhou, Zhejiang, during the typhoon, the cloth was able to withstand a 150 mm rainstorm. When the surrounding traditional earthen ponds were washed down, the breeding ponds using the cloth were safe and sound, directly saving more than 200000 yuan of economic losses.

3. Anti seepage and recycling water utilization

The anti-seepage properties of the fabric prevent pathogenic bacteria from infiltrating and spreading through groundwater, while supporting a circulating water system to reduce the risk of groundwater pollution. In high-density shrimp ponds in Malaysia, the single pond yield reached 1.2 tons/batch, and the investment return cycle was shortened to 18 months, verifying the direct improvement of aquaculture efficiency by its anti-corrosion design.

4、 Application scenarios and effect verification

1. Extreme environmental adaptability

In projects such as Hanjiang Sturgeon Valley, fabrics are adapted to low temperature (winter) and high temperature (summer) environments, maintaining stable physical properties and reducing material aging and corrosion caused by temperature fluctuations.

2. High density aquaculture support

In high-density aquaculture scenarios such as loaches and eels, the smoothness of the fabric surface reduces friction damage to the fish body and significantly improves survival rates. At the same time, its tear resistance prevents the fish from being scratched by rough pool walls, reducing the risk of secondary infection.

3. Long term cost advantage

The service life of the fabric can reach 8-10 years, with a 60% reduction in maintenance frequency. Compared to traditional materials such as PE fabric, it needs to be replaced every 3-5 years, resulting in lower long-term operating costs.
