I. Product Definition
The QDPP Integrated Sewage Treatment Equipment from Shandong Zhongqiao Enlightenment Environmental Protection Equipment Co, Ltd. embodies a pinnacle of innovation. Expertly crafted with cutting-edge high-molecular materials, this equipment is a testament to endurance and excellence. Its seamless, single-piece tank design epitomizes strength and reliability. Our avant-garde R&D team has not only overcome challenging design barriers but has elevated Western technological concepts to uniquely address the sewage treatment necessities of rural China. This has resulted in a versatile suite of integrated solutions, including the Zhong Qiao Tank Horizontal Tank A/B, Vertical Tank A/B, and the revolutionary Hollow Tank, all of which stand as benchmarks of innovation and quality.
II. Superior Raw Materials
Our choice of high-modulus polypropylene as the foundation of our subterranean drainage and wastewater solutions is a testament to our unwavering commitment to excellence. With an elastic modulus that soars to ≥1500 MPa, it surpasses the 800 MPa of HDPE, ensuring outstanding ring stiffness and robust structural integrity, crucial for demanding applications.
Renowned for its non-toxic and odorless attributes, polypropylene's highly crystalline structure and ultra-light density of 0.90-0.91 g/cm³ contribute to its exceptional stability in water, demonstrated by a minuscule absorption rate of just 0.01%. Its molecular weights, ranging from 80,000 to 150,000, guarantee excellent molding capabilities and a polished, appealing finish, making it an ideal choice for diverse applications.
Exhibiting exceptional chemical stability, polypropylene resists a wide array of chemical agents, although care is advised with concentrated sulfuric and nitric acids. While it interacts with certain hydrocarbons, its heightened crystallinity enhances its chemical resilience, establishing it as a prime material for manufacturing robust, corrosion-proof components across a variety of applications.
Polypropylene, being non-toxic and odor-free, offers superior strength, stiffness, and heat resistance compared to low-density polyethylene, performing optimally at temperatures near 100°C. It boasts excellent dielectric properties and maintains high-frequency insulation independent of moisture, making it a versatile material for a multitude of industrial and commercial applications.
With broad resistance to common acids, bases, and organic solvents, polypropylene is exceptional for applications involving food-grade utensils where safety and durability are key priorities.
PPH, a high molecular weight, low melt flow homopolypropylene, benefits significantly from β-modification, resulting in a finely crystalline structure that enhances its chemical and temperature endurance, as well as creep resistance and impact resilience at low temperatures. This makes it ideal for rigorous environments.
