I. Product Definition
Delve into the world of advanced engineering with the QDPP Integrated Sewage Treatment Equipment, a pinnacle of modern technology by Shandong Zhongqiao Enlightenment Environmental Protection Equipment Co, Ltd. Expertly crafted using cutting-edge high-molecular materials, this equipment stands as a testament to durability and superior performance, thanks to its innovative seamless tank construction. Our inspired R&D team has adeptly tailored Western technologies to meet the distinct sewage treatment demands of rural China. This groundbreaking effort has resulted in a comprehensive suite of integrated solutions, including the Zhong Qiao Tank Horizontal Tank A/B, Vertical Tank A/B, and the revolutionary Hollow Tank, each a beacon of outstanding ingenuity and excellence.
II. Superior Raw Materials
In our pursuit of excellence, we have meticulously selected high-modulus polypropylene as the fundamental material for our underground drainage and wastewater solutions. With an impressive elastic modulus of ≥1500 MPa, significantly surpassing HDPE's 800 MPa, it guarantees exceptional ring stiffness and robust structural integrity, vital for superior performance in demanding applications.
Polypropylene is distinguished by its non-toxic, odorless qualities, featuring a highly crystalline structure and an ultra-light density of 0.90-0.91 g/cm³. Its exemplary water stability is highlighted by an absorption rate of just 0.01%. Furthermore, with molecular weights between 80,000 to 150,000, polypropylene excels in molding and offers a refined, attractive finish, making it the material of choice for diverse applications.
Renowned for its chemical stability, polypropylene can endure exposure to a broad spectrum of chemicals, although caution is needed with concentrated sulfuric and nitric acids. Despite its interactions with certain hydrocarbons, its enhanced crystallinity bolsters its chemical resistance, making it ideal for crafting robust, corrosion-resistant components across numerous applications.
As a non-toxic, odor-free material, polypropylene outshines low-density polyethylene with superior strength, stiffness, and heat resistance, performing exceptionally up to 100°C. Its outstanding dielectric properties and high-frequency insulation remain unaffected by moisture, making it a highly versatile material for a multitude of industrial and commercial applications.
Exhibiting excellent resistance to common acids, bases, and organic solvents, polypropylene is well-suited for food-grade utensil applications, where safety and durability are critical.
PPH, a high molecular weight, low melt flow homopolypropylene, benefits from β-modification, resulting in a finely crystalline structure that greatly enhances its chemical and temperature endurance, along with improved creep resistance and impact resilience even at low temperatures, making it perfect for rigorous environments.
