II. Raw Materials
Engineered with premium high-modulus polypropylene, this exceptional material is the epitome of excellence for subterranean drainage, sewage, and wastewater management. Boasting an impressive elastic modulus of ≥1500 MPa, it far surpasses the mere 800 MPa of traditional HDPE. This superior elastic modulus translates directly to enhanced ring stiffness, ensuring unmatched durability and performance.
Polypropylene stands as a paragon of purity and performance-a non-toxic, odorless, tasteless, and highly crystalline polymer in pristine white. Its feather-light density of merely (0.90-0.91 g/cm³) positions it among the lightest and most versatile plastics. With water stability and an absorption rate as low as 0.01%, complemented by a molecular weight ranging from 80,000 to 150,000, it offers excellent molding prowess and a lustrous finish.
Renowned for its outstanding chemical stability, polypropylene resists a plethora of chemical reagents. While it may yield to concentrated sulfuric and nitric acids, its resilience remains unchallenged against various other corrosive substances. Enhanced crystallinity fortifies its chemical stability further, making it an ideal choice for crafting robust, corrosion-resistant chemical equipment.
This non-toxic, odorless polypropylene boasts superior strength, stiffness, and heat endurance, eclipsing low-density polyethylene. Usable at temperatures up to 100°C, it also offers remarkable dielectric properties and high-frequency insulation, unfazed by humidity, solidifying its status as a premium material.
Withstanding the tests of common acids, bases, and organic solvents, polypropylene emerges as the perfect material for safe and reliable food utensils, ensuring hygiene and quality.
PPH represents a pinnacle of innovation-a high molecular weight, low melt flow rate homopolypropylene that, through advanced β-modification, achieves a refined crystalline structure. This grants it superb chemical and high-temperature resistance, excellent creep resistance, and outstanding low-temperature impact resilience.
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 |
Ideal for a myriad of industries, including wastewater treatment,
air pollution control, pioneering lithium battery new energy, chemical, metallurgy, electroplating,
chemical fiber, dyeing, environmental protection, petroleum, electronics, pharmaceuticals, food, oils, light industry, acid production, acid washing, and
innovative battery materials.
IV. Structural Appearance
Main Equipment Color: While a sophisticated light gray is the standard, we offer custom color options to suit your specific preferences.
Equipment Structure: Choose between a solid wall structure for added robustness or a hollow structure for versatile applications.
V. Production Process
The QDPP Integrated Sewage Treatment Equipment employs a cutting-edge one-time forming and multi-layer winding production process. Wall thickness varies from 10-80 mm, meticulously tailored to your requirements. This complex process involves winding the foundational layer, allowing complete cooling and crystallization, before effectively releasing internal stresses. A reheating step prepares for additional layer windings, ensuring precision thickness and joint integrity for unparalleled durability.
VI. Welding Process
Our cutting-edge external welding process sets the benchmark for precision and strength, utilizing imported automatic extrusion welding machines. This advanced technique allows us to achieve robust welds in the critical stress zones of the tank in a single operation. By employing premium PPH pellets, identical to the original tank material, these are thermally fused at the weld seams, establishing a seamless and enduring bond with the tank's base and body.
Characteristics:
1. Our system is highly mechanized and automated, ensuring that every unit exudes consistent and exceptional product quality.
2. The weld seams are meticulously engineered, tailored to the product's stress characteristics, thus maximizing their structural integrity and durability.
3. Boasting superior product integrity, the welds merge flawlessly with the tank, offering outstanding resistance to corrosion and ensuring a leak-proof experience.
4. With minimal flash, the seams are remarkably smooth, providing a clean and visually appealing finish.
5. Enhanced with UV absorbers, our PPH pellets are designed to resist aging effectively and significantly prolong the service life of the tank.
Internal Welding
Our internal welding process employs the sophisticated automatic long-arm extrusion welding technology, a pivotal step in our operation. Premium PPH pellets, sharing the same composition as the tank material, are thermally bonded at the internal seams, seamlessly integrating with the tank's base and body. While the fundamental principle mirrors that of external welding, the equipment we utilize is uniquely tailored for this phase.
Characteristics:
1. Our highly mechanized and automated system guarantees stable, high-quality products with every production run.
2. Seam designs, specifically catered to the product's stress characteristics, ensure maximum integrity and strength.
3. Delivering outstanding product integrity, the welds become an integral part of the tank, providing excellent corrosion resistance and leak-proof performance.
4. The reduction of flash results in smooth, aesthetically pleasing seams that enhance the overall appearance.
5. With the addition of UV absorbers to the PPH pellets, the material is fortified against aging, thereby extending the tank's longevity.
