Introducing the QDPP Integrated Sewage Treatment Equipment, an exceptional feat of engineering excellence brought to you by Shandong Zhongqiao Enlightenment Environmental Protection Equipment Co, Ltd. Crafted with precision using cutting-edge high-molecular materials, this equipment represents the pinnacle of innovation and efficiency. Expertly molded into a seamless, single-piece tank, our visionary R&D team has surpassed boundaries by integrating and refining renowned Western technologies. This forward-thinking series is meticulously designed to cater to rural China's distinctive sewage conditions and discharge standards, offering versatile models such as Zhong Qiao Tank Horizontal Tank A/B, Vertical Tank A/B, and Hollow Tank.

Empowered by the robust strength of high-modulus polypropylene, the QDPP equipment is engineered for peak performance in subterranean drainage and wastewater treatment applications. This remarkable material, boasting an impressive elastic modulus of ≥1500 MPa, far exceeds HDPE's 800 MPa, significantly enhancing the product's ring stiffness. This stands as a testament to its unmatched structural integrity and durability.

Our polypropylene is a non-toxic, odorless, and tasteless polymer, celebrated for its lightweight nature and superior crystalline structure. With an exceptionally low density of only 0.90-0.91 g/cm³, it is one of the lightest plastics available. Its extraordinary stability in water, with an absorption rate of a mere 0.01%, coupled with a molecular weight ranging between 80,000 to 150,000, ensures superior molding capabilities and a lustrous, appealing finish.

Polypropylene's exceptional chemical stability renders it resilient against a broad spectrum of chemical agents. Although it withstands many, it is vulnerable to erosion by concentrated sulfuric and nitric acids. It may soften in the presence of certain hydrocarbons, but its heightened crystallinity ensures improved chemical stability, making it an ideal choice for corrosion-resistant chemical equipment and components.

This non-toxic, odor-free polymer is distinguished for its low density and outstanding mechanical properties. It excels in strength, rigidity, hardness, and thermal resistance compared to low-density polyethylene, maintaining its functionality at temperatures around 100°C. Its impressive dielectric properties and high-frequency insulation are unaffected by humidity, positioning it as a versatile choice for numerous applications across industries.

Its resilience against common acids, bases, and organic solvents makes polypropylene an exceptional material of choice for food utensils and other applications demanding robust chemical resistance.

PPH, a high molecular weight homopolypropylene, features a low melt flow rate and refined crystalline structure through β-modification. With its superior chemical resistance, remarkable high-temperature endurance, impressive creep resistance, and exceptional low-temperature impact resistance, it is indispensable for demanding industrial applications.

1. Safety

   The tank is manufactured using a spiral extrusion winding-one-time forming technology. The tank is formed directly from granular raw materials through molds, achieving a seamless, one-piece structure.

2. Durability

   The raw materials include UV-resistant and anti-aging additives, addressing the issue of short outdoor service life for plastic equipment and significantly extending its lifespan.

3. Economic Efficiency

   The tank can have a thickness of over 80 mm, with a tapered cross-section. The thickness can be increased in areas with greater stress at the lower part of the tank, optimizing the use of materials where needed.

4. Corrosion Resistance

   It exhibits excellent resistance to various acids and bases and can store most organic and inorganic acids, bases, salts, and some organic solvents (see the corrosion data sheet for details).

5. Flexible and Convenient Installation

   Lightweight, easy to install and maintain, non-toxic, non-scaling, and non-contaminating. It is user-friendly, customizable according to customer needs, and allows for flexible overall installation.

6. Wide Application Range

   Perfectly suited for deployment across a wide variety of sectors including wastewater management, air quality control, the advancing lithium battery technologies, the chemical industry, metallurgy, electroplating, chemical fibers, dyeing, environmental conservation, petroleum processing, electronics, pharmaceuticals, food production, oil industries, light manufacturing, acid creation, acid cleaning, and battery material development.

Main Equipment Color: Our equipment predominantly flaunts a modern light gray, with customization options available to meet specific client preferences.

Equipment Structure: Select between a robust solid wall structure or an innovative hollow structure to precisely meet your specific needs.

The QDPP equipment is subject to a sophisticated production process, showcasing one-time forming combined with advanced multiple winding techniques. Wall thickness ranges from 10-80 mm, ensuring adaptability to diverse application requirements. The process involves winding a base layer, ensuring full crystallization, then reheating the surface before applying additional layers. The number and thickness of these layers are meticulously crafted to meet specific joint and performance criteria.

Discover the zenith of welding excellence with our state-of-the-art imported automatic extrusion welding machines. These cutting-edge machines deliver robust welds precisely where the tank endures the most stress, ensuring remarkable efficiency. Our groundbreaking process meticulously thermally fuses new PPH pellets, matching the tank's material perfectly, at the weld seams. This meticulous integration results in an incredibly solid and unified bond between the tank's bottom and body, significantly boosting durability and performance.

• Our pioneering mechanization and automation processes assure a consistently superior product quality that not only meets but surpasses industry standards, offering unmatched reliability you can depend on.
• Every weld seam is crafted with precision, tailored to align with the product's stress dynamics, optimizing their integrity and robustness for unparalleled durability.
• The extraordinary integrity of our products ensures that welds become an inseparable part of the tank, providing exceptional resistance to corrosion and a leak-proof performance that endures over time.
• Revel in reduced flash and impeccably smooth seams that enhance functionality while offering a visually striking aesthetic, elevating your product's appeal.
• Our PPH pellets are expertly infused with UV absorbers, offering robust protection against aging and dramatically prolonging the lifespan of your equipment.

Our internal welding is powered by cutting-edge automatic long-arm extrusion welding technology, a pivotal component of our production process. By utilizing new PPH pellets identical to the tank material, we ensure a seamless thermal fusion at the internal weld seams. This strengthens the union between the tank bottom and body, reflecting the principles of our external welding with the use of specialized equipment for outstanding results.,
