This includes the Zhong Qiao Tank Horizontal Tank A/B, Vertical Tank A/B, and the innovative Hollow Tank, each setting a new standard of brilliance and ingenuity.
II. Superior Raw Materials
Our steadfast devotion to excellence shines through in our choice of high-modulus polypropylene as the foundation for our underground drainage and wastewater innovations. Boasting an impressive elastic modulus of ≥1500 MPa, far surpassing HDPE's 800 MPa, it guarantees remarkable ring stiffness and structural integrity, pivotal for high-performance applications.
Polypropylene distinguishes itself as a non-toxic, odor-free marvel with a highly crystalline structure and a feather-light density of 0.90-0.91 g/cm³. Its water resistance is exemplary, with only 0.01% absorption. Furthermore, showcasing molecular weights between 80,000 to 150,000, polypropylene offers exceptional moldability and a refined finish, making it the premier choice for an array of applications.
Polypropylene's chemical resilience is exceptional, allowing it to withstand a wide range of substances, with caution needed only around concentrated sulfuric and nitric acids. While some hydrocarbons may interact, its superior crystallinity enhances its chemical resistance, making it the ideal choice for crafting durable, corrosion-resistant components for various applications.
Being toxin and odor-free, polypropylene outperforms low-density polyethylene in strength, stiffness, and heat resistance, excelling at temperatures up to 100°C. It possesses outstanding dielectric properties and high-frequency insulation unaffected by moisture, rendering it adaptable for a broad spectrum of industrial and commercial purposes.
Offering remarkable resistance to common acids, bases, and organic solvents, polypropylene is perfectly suited for applications like food-grade utensils, where safety and longevity are paramount concerns.
PPH, recognized for its high molecular weight and low melt flow homopolypropylene characteristics, is further enhanced by β-modification, creating a finely crystalline structure that boosts its chemical and thermal endurance, creep resistance, and impact resilience at low temperatures, making it ideal for demanding environments.
