Aquaculture Membrane (Impermeable Membrane/棚膜)

Product Overview

Aquaculture membrane is a specialized functional membrane developed specifically for aquaculture applications. It is divided into two main categories: impermeable membranes and greenhouse cover membranes, comprehensively meeting the full range of usage requirements in both freshwater and marine aquaculture. Impermeable membranes are primarily used for lining the bottoms and slopes of aquaculture ponds, with the core function of isolating the cultured water from the natural soil, preventing pond leakage, and maintaining a stable aquaculture environment. Greenhouse cover membranes, on the other hand, are employed to construct the frame structures above aquaculture ponds, enabling precise temperature control within the greenhouse, extending the growth cycle of farmed organisms, while also blocking external air pollutants and debris from entering the cultured water, thereby reducing the incidence of diseases, minimizing losses during winter and summer periods, and helping farmers enhance their overall economic returns. During production, carbon black can be added to achieve UV resistance and weather durability, or flame retardants can be incorporated to improve fire resistance, ensuring adaptability to diverse regional conditions and farming practices.

Product Classification and Functional Description

Based on their specific functions, aquaculture membranes are categorized into impermeable membranes and greenhouse cover membranes. Each type has distinct application scenarios and core functionalities, and they can be used in combination to build a comprehensive aquaculture protection system.
The first category is the aquaculture impermeable membrane, which is mainly laid at the bottom and along the slopes of freshwater or marine aquaculture ponds, serving as the core material for leak prevention. Its primary role is to completely isolate the cultured water from the underlying natural soil, preventing seepage through soil pores and avoiding the infiltration of impurities and harmful substances from the soil into the water, thus stabilizing pond water levels and quality from the source. This type of membrane is suitable for fish, shrimp, crab ponds, lotus root ponds, ecological aquaculture ponds, and other types of aquaculture water bodies, effectively addressing common issues associated with traditional earthen ponds, such as leakage, slope erosion caused by water flow, and unstable water quality due to soil influence.
The second category is the aquaculture greenhouse cover membrane, primarily installed on the overhead frame structure above aquaculture ponds, serving as a key component for environmental regulation. Its core function lies in leveraging the membrane’s light-transmitting and heat-insulating properties to enable controllable temperature adjustments inside the greenhouse—raising indoor temperatures in winter to prevent frost damage to farmed organisms, and providing shade and insulation in summer to avoid overheating of the water, thereby extending the optimal growth period of farmed species and reducing losses during winter and summer. At the same time, the greenhouse membrane fully blocks external air pollutants, floating debris, bird droppings, and other contaminants from entering the cultured water, cutting off disease transmission routes, lowering the incidence of aquaculture-related illnesses, and reducing medication costs and losses for farmers.

Core Technical Parameters

The core performance parameters of this aquaculture impermeable membrane are as follows; all figures represent standard values verified through actual production testing, reliably satisfying the needs of various aquaculture settings:
1. Permeability coefficient: <1×10⁻¹² cm/s. This parameter indicates an exceptionally high level of impermeability, completely eliminating water leakage and ensuring no permeation even after prolonged use;
2. Membrane thickness: 0.3–1.0 mm. Depending on specific aquaculture requirements, users can select membranes of appropriate thickness—thicker membranes offer superior puncture resistance, aging resistance, and longer service life.
Performance characteristics of the greenhouse cover membrane can be tailored according to custom needs, allowing adjustment of light transmittance, thermal insulation, and UV resistance levels to suit different regional climates and farmed species.

Industry Pain Points Addressed

This aquaculture membrane specifically tackles several longstanding challenges inherent in traditional aquaculture practices:
1. Pond leakage: Traditional earthen ponds often suffer from frequent water leaks, requiring constant replenishment, wasting resources and destabilizing water levels, hindering organism growth. With a permeability coefficient below 1×10⁻¹² cm/s, this impermeable membrane eliminates leakage entirely, stabilizes water levels, and reduces water-replenishment costs;
2. Unstable water quality: Impurities and harmful substances from the soil frequently seep into the water, causing fluctuating water quality and compromising organism health. This impermeable membrane provides complete isolation between water and soil, preventing soil contaminants from entering the water, stabilizing water quality, and cutting down on water-quality adjustment expenses;
3. Slope erosion: Long-term water erosion of earthen pond slopes often leads to collapses and soil loss, necessitating regular maintenance. Laying this impermeable membrane on slopes helps resist erosion, prevent collapses, and lower maintenance costs;
4. Airborne contamination: Open-air aquaculture ponds are prone to pollution from airborne contaminants, floating debris, and bird droppings, resulting in frequent outbreaks of disease. This greenhouse cover membrane effectively blocks external air pollutants from entering the water, severing disease transmission pathways, reducing illness rates, and improving overall farm productivity;
5. Temperature fluctuations: In open-air farming, water temperatures are heavily influenced by external weather conditions—too cold in winter, too hot in summer—leading to frost damage or heatstroke among farmed organisms and substantial losses during seasonal transitions. This greenhouse cover membrane efficiently regulates indoor temperatures, mitigating the impact of external temperature changes on the water, extending the growth cycle of farmed species, and reducing losses during winter and summer.

Core Value of the Product

The core value this aquaculture membrane brings to farmers is reflected in the following aspects:
1. Reduced farming costs: By preventing water leakage with impermeable membranes, farmers cut down on water-replenishment expenses; by blocking pollution with greenhouse cover membranes, they lower disease incidence and medication costs; and by minimizing slope collapses and water-quality fluctuations, they reduce maintenance expenses, ultimately lowering overall farming costs;
2. Increased farming income: Stabilizing the aquaculture environment boosts organism growth rates and survival rates; temperature regulation extends the growing season, enabling off-season farming and higher product prices; and reducing losses during winter and summer increases total yield, enhancing farmers’ economic returns;
3. Versatility across diverse scenarios: Offering customizable formulations and specifications, this membrane adapts to freshwater, marine, varying climatic zones, and different farmed species, ensuring suitability for both small-scale operations and large-scale farms;
4. Long-term reliability: With weather-resistant and UV-protected properties, the membrane maintains durability even under prolonged outdoor exposure, offering extended service life and lower long-term costs, delivering superior value for money.
