PVC square pipes for aquaculture water lines are widely used in large-scale aquaculture due to their corrosion resistance, lightweight and easy installation, low cost, low risk of water accumulation and pollution, and stable and easy-to-fix structure. Their square shape effectively saves space and prevents rolling. They are primarily used for precise water supply during the aquaculture process. Specific application areas can be categorized as follows: 1. PVC Square Pipes for Aquaculture Water Lines in Livestock and Poultry Farming (Core Application Scenario) Livestock and poultry farming places high demands on the stability, hygiene, and ease of maintenance of drinking water systems. PVC square pipes for aquaculture water lines are the mainstream choice for intensive farms, primarily for automatic drinking water systems, covering the following specific applications:

PVC soft door curtain equipment, the surface is not smooth, and has pitting/particles during production. Symptoms: The curtain surface is rough, with small bumps or white particles distributed throughout. In severe cases, it feels rough. Core causes: Raw material problems: PVC resin powder agglomerates due to moisture (moisture content > 0.3%), uneven dispersion of additives such as plasticizers and stabilizers, or impurities (such as dust or plastic debris) mixed into the raw materials.

Core Causes: 1. Insufficient raw material drying: This easily leads to bubble formation during extrusion; uneven mixing of moisture and melt results in silver streaks. 2. Localized overheating of the extruder barrel: Excessive temperature causes degradation of the ABS molecular chains, producing small volatile molecules that form surface pitting. 3. Impurities or excessive moisture in recycled material: Failure to re-dry recycled material or the presence of dust after pulverization exacerbates defects.

Affordable: Suitable for temporary use when you're short on cash. Durable: Highly cold-resistant, they maintain their flexibility even at -70°C, resisting deformation or breakage. Fireproof: Non-flammable and highly flame-retardant, they're ideal for use in flammable environments like chemical plants and printing plants. Insect-Repellent: The orange-yellow soft door curtains emit special light waves to repel insects. Soundproof: They're highly wear-resistant, corrosion-resistant, and moisture-resistant. Environmentally Friendly: Made from domestically sourced, environmentally friendly materials, they're non-toxic and harmless, ensuring a pleasant environment.

Seedling tray equipment is mainly used for the automated production of disposable plastic seedling trays, vegetable seedling trays, succulent seedling trays, rice seedling trays, and fruit and vegetable seedling trays. It is a core forming equipment for modern agricultural seedling cultivation and landscaping. It is compatible with raw materials such as PVC, PS, PP, and ABS, and can produce seedling trays of various specifications, including multi-hole, thickened, deep-hole, and shallow-hole types.
