Product Description

I. Product Definition

Introducing the QDPP Integrated Sewage Treatment Equipment, a testament to cutting-edge engineering by Shandong Zhongqiao Enlightenment Environmental Protection Equipment Co, Ltd. This innovative marvel is crafted from advanced high-molecular materials, representing the pinnacle of efficiency and modernity. Sculpted into a seamless, single-piece tank, it exemplifies the fusion of innovative design and renowned Western technological advancements. This groundbreaking series is expertly tailored to address the distinctive sewage conditions and discharge standards of rural China. With a versatile array of models including Zhong Qiao Tank Horizontal Tank A/B, Vertical Tank A/B, and Hollow Tank, this equipment offers solutions that are both adaptive and robust.

II. Raw Materials

Leveraging the robust properties of high-modulus polypropylene, the QDPP equipment redefines performance in buried drainage and wastewater treatment scenarios. This exceptional material boasts an elastic modulus of ≥1500 MPa, surpassing HDPE's 800 MPa, and significantly amplifying the product's ring stiffness, a true reflection of its unparalleled structural strength and durability.
Our premium polypropylene is a non-toxic, odorless, and tasteless polymer celebrated for its lightweight nature and superior crystalline structure. With a minimal density of just 0.90-0.91 g/cm³, it is among the lightest of plastics. Its exceptional hydrophobic stability-with an absorption rate of a mere 0.01%-combined with a molecular weight between 80,000 to 150,000, ensures superior molding capabilities and a lustrous finish that exudes quality.

Polypropylene's extraordinary chemical stability equips it to withstand a wide spectrum of chemical agents. While resilient against many, it is vulnerable to concentrated sulfuric and nitric acids. It may soften when exposed to certain hydrocarbons, but its enhanced crystallinity ensures superior chemical resilience, making it the material of choice for corrosion-resistant chemical equipment and components.
This non-toxic, odorless polymer is renowned for its low density and exceptional mechanical properties. It boasts superior strength, rigidity, hardness, and thermal resistance compared to low-density polyethylene, maintaining performance even at temperatures around 100°C. Its impressive dielectric properties and high-frequency insulation remain unaffected by humidity, making it a versatile choice for a vast range of applications.
Its formidable resistance to common acids, bases, and organic solvents renders polypropylene an ideal choice for food utensils and other applications demanding robust chemical resilience.
PPH, a high molecular weight homopolypropylene, showcases a low melt flow rate and a refined crystalline structure due to β-modification. Its outstanding chemical resistance, high-temperature durability, remarkable creep resistance, and exceptional impact resistance at low temperatures make it indispensable for rigorous industrial applications.



II. Characteristics



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 diverse sectors, including wastewater management,
air quality control, cutting-edge lithium battery technology, the chemical industry, metallurgy, electroplating,
chemical fibers, dyeing, environmental protection, petroleum processing, electronics, pharmaceuticals, food production, oil industries, light manufacturing, acid generation, acid cleaning, and
battery material advancement.

IV. Structural Appearance
Main Equipment Color: Our equipment predominantly features an elegant light gray, with customization options available to align with specific client preferences.
Equipment Structure: Choose from a durable solid wall structure or an innovative hollow structure to precisely meet your requirements.



V. Production Process
The QDPP equipment is produced through a sophisticated manufacturing process, merging one-time forming with advanced multiple winding techniques. Wall thickness ranges from 10-80 mm, ensuring adaptability to diverse application needs. The process incorporates winding a base layer for full crystallization, followed by surface reheating before additional layers are applied. The number and thickness of these layers are meticulously tailored to meet specific joint and performance standards.

VI. Welding Process

Experience the epitome of welding excellence with our premium imported automatic extrusion welding machines. These cutting-edge machines deliver substantial welds in the most critical stress areas of the tank, achieving remarkable efficiency. Our ingenious process seamlessly integrates new PPH pellets, identical to the tank material, at the weld seams through thermal fusion. This creates an exceptionally robust union between the tank bottom and body, significantly enhancing durability and performance.



Key Features and Advantages:

1. Our leading-edge mechanization and automation processes ensure superior product quality, consistently surpassing industry standards with exceptional reliability and consistency.
2. We expertly design weld seams to align with the product's stress dynamics, optimizing their strength and robustness.
3. The outstanding product integrity we provide ensures welds become a seamless part of the tank, delivering extraordinary corrosion resistance and a leak-proof performance that lasts.
4. Experience reduced flash and impeccably smooth seams that are not only functionally superior but also visually appealing, enhancing the product's aesthetic value.
5. Our PPH pellets are meticulously infused with UV absorbers, effectively preventing aging and greatly extending the service life of your equipment.


Precision Internal Welding

Our internal welding utilizes cutting-edge automatic long-arm extrusion welding technology, a pivotal step in our production process. By using new PPH pellets, identical to the tank material, we thermally fuse them at the internal weld seams. This process reinforces the bond between the tank bottom and body, incorporating the principles of external welding while using specialized equipment for unparalleled results.


Distinctive Features:
1. Our highly mechanized and automated processes consistently deliver superior product quality, setting innovative benchmarks for excellence.
2. Weld seams are meticulously engineered in line with the product's distinct stress characteristics, ensuring optimal structural integrity and resilience.
